Asia Foundry Association Established 亚洲铸造业联合会在曼谷正式成立

O

n Sep. 18, 2019, the first day of Metal+Metallurgy Thailand, 12 foundry organizations of Asian countries and regions were getting together in the City of Angels-Bangkok to attend the founding conference of Asia Foundry Association, signing the Constitution of Asia Foundry Association and witnessing this important moment which was a milestone for the Asian foundry industry. From this moment on, the Asia Foundry Association has announced its formal establishment.

Asia has a vast territory, a large population and abundant resources. The development prospect of the foundry industry is broad. This is our advantage. However, we also have disadvantages because of the different cultural backgrounds and language barriers among Asian countries and regions. In Asia, there are large foundry nations, such as China, India, Japan, and South Korea, but there are also countries and regions with few foundry industries, such as Laos and Myanmar. Of course, there are more countries like Vietnam, Thailand, Indonesia, and Malaysia where the foundry industry is booming. The development level of the foundry industry varies from country to country, and the demand is very different. Building a common communication platform has become an urgent need for the development of the foundry industry in Asia. In 2010, Asia Foundry Forum was successfully held under the active preparations of foundry organizations of seven countries and regions in Asia. It has been held for five consecutive years and has become an important platform for the communication of the Asian foundry industry. Today, Asia Foundry Association has been established on the basis of Asia Foundry Forum. The founding numbers has reached 12, and their casting production account for 65% of the world total. In the future, with the sustainable development of the Asian foundry industry, our members will grow large and be prosperous.

Thank you for all your support. As the first president of the Asia Foundry Association, I am honored and also aware of the great responsibility. Thank you for your trust in setting up the Secretariat at China Foundry Association. Hereby, on behalf of China Foundry Association, I will lead the team of Asia Foundry Association’s Secretariat to serve the development of the Asian foundry industry, promote exchanges and cooperation, and strengthen talent education and training to improve the overall level of foundry technology, management, safety and environmental protection, and promote the sustainable development of the Asian foundry industry.

Thank you! ■

Taiyuan heavy machinery casts world's largest high-end steel part 世界最大高端铸钢件在太重诞生 The 35,000-ton multi-directional composite extruder manufactured by Taiyuan Heavy Machinery for Nanjing Develop is the largest pressing machine in the world. The main components are produced in Tianjin Binhai Lin’gang Base of Taiyuan Heavy Machinery, and four supporting castings are produced in Taiyuan. They are the largest castings in the world. On December 10, the lower beam of Nanjing Develop’s 350MN press was transported to Tianjin. The remaining three pieces were also transported in mid-March, mid-May and mid-June.

Four giant steel castings delivered by Taiyuan Heavy Machinery will be used in the multi-directional composite extrusion hydraulic die forging equipment for the contract signed between Taiyuan Heavy Machinery Binhai Forging Company and Nanjing Develop Advanced Manufacturing Co., Ltd. The main parts of the press are manufactured, machined and assembled by the Binhai Forging Company. Four parts of the upper and lower beams and double columns of the press machine are produced by the foundry company of Taiyuan Heavy Machinery. The column has a weight of 565 tons and an upper beam of 537 tons.

The total weight of the four components is over 2,000 tons. The production of the column and upper beam has exceeded the design limit of Taiyuan Heavy Machinery, especially the largesize column outline, complex structure, different wall thickness, poor manufacturability, are all challenges and brings safety risks toward the capabilities of steel melting, lifting, heat treatment, rough machining equipment and casting transportation.

To ensure the quality of the product, the material selection is the first step. The materials of the four large pieces of giant castings are selected in accordance with European standards: the yield strength and tensile strength performance values are much higher than the standard, the key parts of the castings require ultrasonic flaw detection to reach the third level of European standard. The weld sealing level for sand hole is required to reach the first-level of flaw detection, which is also a great challenge to the staff.

There are several major innovations in the product: continuous optimizing and establishing new processes and process parameters using software to make simulations of all kinds of casting, solidification, heat treatment and other processes; strictly controlling the chemical composition and gas content of materials, optimizing the refining process of molten steel, optimizing the normalizing heat treatment process, ensuring that the mechanical properties of the test parts meet the requirements of the drawings; the first scientifically safe crossover runner pouring and five hanging bags furnace pouring.

The casting of these complex structural parts of columns and upper beams is the first in China and has reached the leading level in the world foundry industry. ■

Construction of river-crossing immersed pipes construction completed 新兴铸管：首例过河沉管作业顺利完成 Recently, on the Xipi River of Anhui Province, the first case of a river-crossing immersed pipe construction of Lu'an Dushan Town Water Plant project was successfully completed with the active participation of Xinxing’s after-sales service team.

Before construction started, Shi Qiang, Xinxing’s sales manager, and Lu Chuanqing, Xinxing’s after-sales technician, arrived at the site in advance to check the topography of the site. They did preparations like constructing river bottom cofferdam and excavating the trench. The condition of on-site construction is very difficult, and some local people said it is impossible for the county. Continuous rainy days and turbulent water flow, coupled with the soft soil of the river bottom trench, posed great difficulties for the construction of the project, because the use of conventional tractor technology may lead to river collapse. It seemed like the Xipi River had turned into an insurmountable obstacle that had stopped Xinxing people.

Mountains multiply and streams double back. However, there is a way out. Limited by the on-site construction conditions, the after-sales technician Lu Chuanqing and others figured out a solution. After DI pipes were sealed, the resulting enclosed space helped the pipes floating on the surface of the river. The tech plan using this feature to construct the river-

The customer's requirements were very important to Xinxing, and the construction progress could not be stopped.

According to the tech plan, the sales service team of the Xinxing did their best to help the construction team on installing the pipes one by one. More than a 100-meter pipeline was placed along the Xipi riverbank.

Thirty meters from the riverbank, the rushing water flow adds difficulty to the construction, but the team wasn’t deterred.

The after-sales technician and the construction team calculated the distance of the traction, and successfully connected the pipeline to the other side of the river. Then the construction team members began to inject water from the end of the pipeline, draining the air in the pipeline, and using external force to ensure the pipeline was straight. The pipeline began to sink by the gravity of the water inside, and finally sank into the channel at the bottom of the river, and river-crossing immersed pipe construction was successfully completed.

The successful completion of the river-crossing immersed pipe construction reduced construction costs and saved time for the project. A company without on-site standing will be abandoned by the market. Xinxing’s after-sales service team with full responsibility and construction experience helped their clients solve problems. ■

Waupaca opens two facilities 沃帕卡建新厂 AFS Corporate Member Waupaca Foundry, a Hitachi Metals company, opened its manufacturing plant in Ironwood, Michigan. The facility will process castings produced in Waupaca, Wisconsin. The facility is expected to create 61 new jobs and an investment of $4.3 million and covers 50,000 sq. ft.

Opening a facility to handle cleaning and finishing of cast parts will allow us to meet customers’ expectations in quality and delivery of their parts,” Waupaca executive vice president John Wiesbrock said.

Waupaca expanded to Ironwood to find more workers.

“Like many employers across the nation Waupaca Foundry is finding ways to overcome low unemployment and a shortage of skilled workers,” Waupaca president, COO & CEO Mike Nikolai said.

The company also announced it is opening a machining operation adjacent to its gray iron foundry located on the east side of Waupaca, Wisconsin. The new machining plant will machine brake components for the commercial vehicle market produced at Waupaca Foundry.

The facility has 50,000 sq. ft. of manufacturing space and will initially employ 15 skilled workers. The decision to expand operations beyond raw castings was to support customer demand.

“Our global markets are changing and customers want a higher level of value-added services,” Wiesbrock said.

“A vertically integrated model such as this takes the waste out of the supply chain for customers.”

Wiesbrock added opening this facility fulfills corporate objectives established in 2016 to vertically integrate services.

Braking components machined in the new facility will be used by heavy duty truck manufacturers. These components are cast and machined on site in Waupaca rather than shipped to Tier 1 suppliers. However, Wiesbrock adds that opening the machining operation will not eliminate the need for other supply chain partners providing machining services. ■

Skuld wins thin-walled ductile iron grant Skuld公司获薄壁球墨铸铁科研基金

Skuld LLC (Columbus, Ohio) received a Small Business Innovative Research grant from the Department of Energy (DOE). The grant will be used to show going to 0.060-in. thick ductile iron can be done without negatively impacting automobile properties.

Skuld’s most recent trials reduced the weight of designs by 70% and material costs by 40%. This is of interest to the DOE due to increasing fuel efficiency standards.

By 2025, the corporate average fuel efficiency standards are supposed to rise to 54.5 mpg, up from 35.

“The average vehicle has 600 pounds of castings,” Skuld co-owner Sarah Jordan said. “Over half the castings are made of iron or steel. To have an affordable solution, the ability to go thinner in iron-based alloys is essential.” ■

World's longest stempost casting produced 世界最长船艏柱铸件铸造完成 On June 13, Ansteel Cast Steel Co. Ltd announced that the stempost parts produced for the world's largest container ship of 22,000 containers have been cast and welded at the Jiangnan Shipyard in Shanghai. The stempost also has set a world record: 15 meters long, 2.9 meters wide, and with a curved arc of 3 meters.

The stempost is the front-end component of the hull. Because it is located at the bow of the ship, it plays the role of cleaving through the waves and navigating, which is required to have sufficient rigidity and strength, as well as a good configuration.

The design and manufacturing team of the stempost castings calculated the reasonable anti-deformation by computer simulation of the stress shrinkage before casting, so the size of each rough part was accurate.

During heat treatment, the infrared ray level is used to correct the level of the casting. Multi anti-deformation support points are designed based on simulating of the deformation trend to ensure the levelness of the casting. CNC is used to ensure that the curved surface arc conforms to the hull, and the three-dimensional scribed line is to ensure the position of the inner ribs. In the post grinding, the casting is leveled by using special supporting iron, and the partial deformation adopts cold orthopedic modification to ensure the straightness during the subsequent heating air-gouging grinding. ■ 20

arth-moving equipment and associated tools are subject to a variety of wear mechanisms, and this proves to be a challenge with respect to qualifying the best material for general application.

Preference for quenched and tempered steels for ground engaging tools is often related to other performance criteria, e.g. fatigue, and notch or fracture toughness. Even in a loosesoil work site, occasional buried and unmovable obstacles produce impact-loading; quenched and tempered steels provide better fracture resistance.

In a study, a Mn-Si-Mo-V steel was formulated to minimize solidification shrinkage porosity with the goal of obtaining a high-strength and impact-resistant steel. Three chemistries, baseline, baseline plus 2 wt. % nickel (Ni) and baseline with 1.5 wt. % Ni but no vanadium (V), were produced keeping a manganese to carbon ratio of 5-1 (Table 1).

Steels were heat treated to produce an average prior austenite grain size of 50-70 µm, a lath martensitic microstructure, and a Stage I tempered hardness of 525-560 HBW (53-55 HRC). Yield strength and ultimate tensile strength averaged 1482 MPa (215 ksi) and 1930 MPa (280 ksi).

于土方作业设备和相关工具受到各种磨损机 制的影响，因此一般应用中，确定适用的最 佳材料是个挑战。

与地面接触的工具的淬火和回火钢性能的选择通常与 其他性能标准相关，例如疲劳度、缺口或断裂韧性。 即使在松散的土壤施工，偶尔出现埋藏物或不可移除 的障碍物时，也会产生冲击力; 淬火和回火钢的抗断裂 性更好。 在一项研究中，为了获得高强度和抗冲击的钢， 定制Mn-Si-Mo-V合金钢，以最小化凝固收缩孔隙度。 研究3种化学成份：基础成份、基础成份+2 wt％镍 （Ni）、基础成份+1.5wt％镍（Ni）但不含钒（V） ，保持锰碳比为5-1（表1）。对钢进行热处理，平均 的原始奥氏体晶粒尺寸为50-70μm，呈现条状马氏体 微观结构，第一阶段的回火硬度为525-560HBW（5355HRC）。屈服强度和极限拉伸强度平均为 1482MPa（215ksi）和1930MPa（280ksi）。

Fig 2. Error bars represent the maximum and minimum values of the two-sample test average. The baseline heat showed the greatest variation with respect to distance from the chill.

vanadium showed the least dependence of tensile ductility with distance from the chill and varied between 11% to 7%.

Impact wear was simulated using a gouging abrasion test, and the alloys demonstrated a 27% to 46% reduction in wear relative to steels currently employed.

All three alloys produced the expected Stage I tempered martensitic microstructure, but the measured hardness was lower than expected for these steels. Most notably in Table 2 was a greater difference between calculated and measured hardness for the Ni-containing alloys. The addition of Ni lowers both the martensite start temperature and the rate of martensite transformation.

Plate martensites are more common when formed below 392F (200C), and as much as 20% plate martensite may be expected for the baseline +Ni steel. Metallographic results appear to corroborate the calculated kinetics. Measurement of prior austenite grain size was in reasonable agreement of the size calculated for the time and temperature that the steel was held prior to quenching (Table 2). The smaller measured grain size observed in the baseline heat is likely due to grain pinning by AlN or VN. In general, the tensile properties decreased with distance from the chill. In a study for cast Cr-Ni-Mo alloys using the same casting configuration, the tensile ductility was shown to

镍的添加可有效提高拉伸塑性和冲击韧性。不含钒 的合金表现出拉伸塑性与冷却间隔的依赖程度最低， 并且在11％-7％之间变化。通过气刨磨损试验模拟冲 击磨损，与目前使用的钢相比，合金钢的磨损降低27 ％-46％。 3种成份的合金都呈现了预期的第一阶段的回火马 氏体微观结构，但测量的硬度低于预期。最明显的 是，如表2所示，含镍（Ni）合金的试验硬度和实际 测量值之间存在较大差异。Ni的添加降低了马氏体的 初始温度和转化速率。 当低于392F（200℃）时，板状马氏体更易形成， 并且对于基础成份+ Ni合金钢，预期可以产生多达 20％的板状马氏体。金相结果似乎证实了计算的动力 学。原始奥氏体晶粒尺寸的测量值与在淬火之前根据 保温的时间和温度计算所得的尺寸一致（表2）。在 对基础成份合金钢热处理时观察到的较小的晶粒尺寸 可能是由于AlN或VN的晶粒钉扎导致。

be related to the maximum pore length measured on the fracture surface. Measurements of pore lengths on tensile fracture surfaces for the alloys reported here are being conducted and will be reported later.

A significant decrease in ultimate tensile strength also was observed when the elongation to failure was less than 4%.

At present there is no method to relate quantitative measurements of porosity as collected on random metallographic cross sections to the maximum shrinkage pore size that might exist in the gage section of a tensile bar.

However, it is reasonable to assume that material with a higher porosity coverage would exhibit lower tensile ductility. A comparison of the porosity coverage between the baseline and the baseline +Ni would support this claim. To obtain a tensile elongation greater than 9% in the baseline +Ni steel would require the area coverage of porosity to be less than 0.024% with a secondary dendrite arm spacing of less than 100µm. A more stringent requirement of lower area coverage would be necessary for the same steel with a greater secondary dendrite arm spacing since the pores would be

larger. This is observed for the baseline +Ni alloy where the same area coverage of 0.024% produced 6.5% elongation to failure with a secondary dendrite arm spacing of 375µm.

The variation in tensile properties with distance from the chill is more significant for the baseline alloy, and other mitigating factors might be contributing to the lower properties than just greater porosity. First, Type II (eutectic) MnS inclusions will lower tensile ductility and notch toughness. Second, the tensile fracture transitioned from a predominately ductile, microvoid coalescence to a brittle cleavage fracture.

Brittle fracture was also observed in the baseline +Ni heat but only in association with porosity, and the pore size was generally smaller in comparison to the baseline chemistry.

In recent work, the cleavage fracture observed close to shrinkage pores in cast HY80 and HY100 steel was associated with M7C3 carbide precipitates with plate-like morphologies.

The higher alloy content in these last regions to solidify could encourage coarse plate-like carbides. However, this fracture feature also was observed for both Charpy V-notch specimen and tensile specimen. In the study presented here, the cleavage like fracture was only observed during tensile testing. Furthermore, the carbide stability study conducted based upon the last 15% liquid does not predict M7C3 formation.

A “fish-eye” fracture feature was noted, and this would be indicative of hydrogen damage if the fracture was intergranular.

It’s been reported the occurrence of hydrogen induced intergranular or transgranular quasi-cleavage fracture largely depends on tramp element (P, Sb, Sn, As) segregation to grain boundaries and the subsequent loss of

枝晶臂间距的相同钢材，对低面积覆盖提出了更严格 的要求。在基础成份+Ni合金中观察到，对于相同的 0.024％的面积覆盖率，断裂伸长率为6.5％、二次枝 晶臂间距为375μm。 对于基础成份合金，其拉伸塑性随冷却间隔的变 化更为显著，而其他削弱因素不仅会产生较大的孔隙 率，还可能导致较差的拉伸延展性。首先，II型（共 晶）MnS夹杂物将降低拉伸塑性和缺口韧性。其次， 拉伸断裂从易延展的微孔集聚型转变为脆性解理断 裂。在基础成份+Ni金属液中也能观察到脆性断裂， 但仅与孔隙度相关；与 基线化合物相比，孔隙 通常较小。 在最近的研究中， 在HY80和HY100钢中 观察到收缩孔处的解理 断裂与具有板状形态的 M7C3碳化物沉淀物相 关。这些最后凝固的区 域中合金含量较高，可 能会助长粗大的片状碳 化物形成。。然而，在 夏比V型缺口试样和拉 伸试样中也观察到这种 断裂特征。在本研究 中，仅在拉伸测试时观 察到解理断裂。此外， 基于最后的15％液相 中进行的碳化物稳定性 研究不能预测M7C3的 形成。 观察到“鱼眼”断 裂特征，如果断裂是 晶粒间的，这表明是

grain boundary cohesive strength. Hydrogen embrittlement is typically studied in Ni-Cr-Mo type steels used in energy production. These steels are usually tempered above 572F (300C), which lowers the soluble carbon in ferrite to that being in equilibrium with cementite (Stage III tempering) or with the alloy carbide formed during secondary hardening. These elevated tempering temperatures also promote tramp element segregation to grain boundaries. Intergranular fracture is also a common fracture mode observed for both tempered martensite embrittlement in plain carbon steels and temper embrittlement in alloy steels in the presence of phosphorus.

Hydrogen induced quasi-cleavage fracture has been reported for the HY-class of steels when the effects of tramp element segregation are mitigated. Quasi-cleavage fracture also has been reported in Stage I tempered steels for a SAE 10B22 steel tempered at 302F (150C). Both boron and carbon increase the cohesive strength of grain boundaries. This lesson was learned during the development of interstitial free steels where intergranular fracture was characteristic of cold work embrittlement. The benefits of Stage I tempering now can be recognized as contributing to grain boundary cohesive strength as a result of the higher carbon content in solution.

The role of shrinkage porosity is similar to blister formation where hydrogen gas accumulates and builds up pressure within a cavity. The pore also can act as an irreversible trap, which is an activation energy greater than 50 kJ/mol. If the hydrogen is not fully removed by baking, then upon austenitization the thermal energy will be sufficient to release the hydrogen back into solution near the pore with austenite having a higher solubility for hydrogen. The pores also may act as stress risers and enhance the sensitivity of the steel to hydrogen as has been shown for martensitic advanced high strength steel.

Hydrogen damage in steels show a strain rate dependence with more damage occurring at slower strain rates.

Charpy impact testing is not immune to hydrogen damage, as has been shown for line pipe steels. Hydrogen damage is manifested as a shift in the ductile to brittle transition temperature to higher temperatures. This shift in temperature is concentration dependent and the magnitude of the shift increases with hydrogen content. Thus, hydrogen induced cracking may be observed. It is thus reasonable to conclude air-melted steels with ultimate tensile strengths in excess 1,860 MPa (270 ksi) may be subject to hydrogen embrittlement and shrinkage porosity may require longer baking times to remove the hydrogen. Thus, the cleavage fracture associated with porosity in these ultra-high strength steels may be an indication of hydrogen damage.

The main difference between the baseline and the Ni-containing alloys can be described by the mode of solidification.

In two calculated phase diagrams using the baseline chemistry with manganese being the independent variable, and then using 1.77 wt.% Mn with the baseline chemistry to plot the phase diagram with Ni as the independent variable, only the baseline composition goes through the peritectic reaction.

Notch toughness as measured by absorbed energy during Charpy impact testing also shows a dependence upon dis26

含有氢元素引起的。据已发表的论文，因为氢残留引 起的晶间或穿晶的解理断裂很大程度上取决于有害元 素（P、Sb、Sn、As）偏析到晶界和随后的晶界凝 聚强度的下降。通常情况下，在发电设备中使用的 Ni-Cr-Mo型铸钢中研究氢脆化。这种钢材通常在高于 572°F（300℃）的温度回火，将铁素体中的可溶性碳 降低到与渗碳体（第3阶段回火）或二次硬化期间形 成的合金碳化物处于平衡状态。升高的回火温度也促 使杂质元素偏析到晶界。对于普通碳钢中的回火马氏 体脆化和在磷存在下合金钢中的回火脆化，沿晶断裂 也是常见的断裂模式。 本文研究了氢导致准解理断裂对H级钢的影响，并 在此基础上减轻了有害元素偏析的影响。。对于在 302°F（150℃）回火的SAE 10B22钢，在第一阶段的 回火钢中也有准解理断裂的报道。硼和碳都增强了晶 界的内聚强度。这些是在无间隙原子钢的研发过程中 总结出来的，其中沿晶断裂是冷加工脆化的特征。由 于溶液中碳含量较高，现在可以认为第一阶段的回火 有助于增强晶界凝聚强度。 缩孔的作用与气泡的形成类似，其中氢气在型腔内 积聚并形成压力。收缩孔也可以视为不可逆的陷阱， 其活化能量大于50kJ/mol。如果通过热处理没有完全 除去氢气，则在奥氏体化时，热能足以将氢释放回缩 孔附近的溶液中，奥氏体具有较高的氢溶解度。如马 氏体高级高强度钢所表现出来的，缩松孔也可以起到 压力冒口的作用并增强钢对氢的敏感性。 钢的氢损伤表现出应变率依赖性，在较慢的应变 速率下发生更多的损伤。夏比冲击试验不能免受氢 损伤，通过管线钢材已得到证实。氢损伤表现为韧性 转变为脆性过程中的温度升到较高。温度的这种变化 取决于浓度，并且偏移的幅度随着氢含量的增加而增 加。从而，可以观察到由于氢诱导产生的断裂。可以 合理地得出结论，具有超过1,860MPa（270ksi）的 极限拉伸强度的空气熔炼钢可能会发生氢脆化，并且 缩松可能需要更长的烘干时间来除去氢。因此，与这 些超高强钢中的孔隙相关的解理断裂可能是发生氢损 坏的迹象。 基础成份和含Ni合金的主要差异可以通过凝固模 式来表述。在两个计算的相图中，首先使用基础化 学反应，其中锰是独立变量，然后使用1.77wt.%的 Mn和基础化学反应来绘制相图，其中Ni作为独立变

tance relative to the chill. Impact energies greater than 20 J (15 ft-lb) were obtained only from steel closest to the chill.

Notch toughness increased with Ni content and overall the baseline +Ni alloy performed the best. Prior austenite grain size did not seem to be a factor, since the measured values for the three alloys were within the error of the measurement (±10%). The role of eutectic solidification of the MnS has not been accounted for, but the sulfur content of 80 ppm is relatively low and the Baseline tensile specimen closest to the chill had elongations to failure of 8% which is reasonable for a cast steel with an ultimate tensile strength of 1986 MPa (288 ksi).

The gouging wear data has been plotted with respect to hardness in Figure 4. The role of microstructure is depicted in Figure 4a and the best performers are the baseline +Ni and the austenitic steel. The same data is plotted in Figure 4b and the results are sorted by YS/UTS ratio. The tensile properties from the second row (away from the chill) were used to represent the steel produced in this study, since the wear test coupons were taken furthest from the chill. The most gouging wear resistant alloys tend to be those with low YS/UTS ratios. Thus, the major conclusion drawn from this study is that both high hardness for wear resistance in loose soil or sand can be combined with a low YS/UTS to produce good gouging wear resistance. The mechanism of this improvement is the rapid rate of work hardening, which is expected to decrease the depth of cutting in the wear scar and thus produce a smaller volume of material removal during each abrasive cut.

The role of Ni in the improved wear properties of the materials tested appears to be in lowering the yield strength to produce a lower YS/UTS ratio, i.e. greater work hardening as Ni is increased. The hardness of the counterbody was less than all three alloys tested from this study. As previously noted, a softer counterbody may produce more aggressive wear as a result of the rock sticking and rolling across the counterbody exposing fresh rock face to the steel being tested. The contribution of Mn-C solid solution defect pair to the work hardening of these Stage I tempered martensitic steels is still speculative, but the results obtained are better than quench and tempered steels with similar Ni contents. The higher wear rates for the baseline steel may be related to porosity and the presence of Type II sulfides.

Gouging wear resistance of quenched and tempered steel is improved by increasing the rate of work hardening as characterized by a low ratio (<0.8) of yield strength to ultimate tensile strength. The alloys formulated in this study would provide an excellent choice for a general application ground engaging tool providing both high hardness for resistance to 2-body wear as encountered in loose or sandy soils and resistance to gouging impact wear associated with rock breaking and crushing. The alloys studied have not been optimized, but provide a good starting point for formulating new steels with improved performance. ■ This article is an adaptation of paper 19-045 presented at the 2019 Metalcasting Congress in Atlanta.

量，只有基础成份可以通过包晶反应。 在夏比冲击试验中，通过吸收的能量测试的缺口韧 性也显示出对于冷却间隔的依赖性。仅从最接近冷却 的钢中获得大于20J（15ft-lb）的冲击能量。随着Ni 含量的增加，缺口韧性增加，总体而言，基础成份+ Ni合金表现最佳。之前的奥氏体晶粒尺寸似乎不是影 响因素，因为三种合金的测量值都在测量误差范围内 （±10％）。MnS共晶凝固的作用尚未得到解释，但 80ppm的硫含量相对较低，最接近冷却的基础成份的 拉伸试样的断裂伸长率为8％，这对于具有极限抗拉 强度为1986 MPa（288 ksi）的铸钢来说是合理的。 图4所示为气刨磨损数据与硬度的关系。图4a表明 了微观结构的作用，并且可以看出最佳性能是基线+ Ni和奥氏体钢。图4b中是相同的数据，但结果按YS/ UTS比率进行排序。第二行（远离冷却）的拉伸性能 适用于本研究中的钢，因为磨损试样来自距离冷却 最远的地方。气刨耐磨合金倾向于具有低YS/UTS比 率。因此，从这项研究中得出的主要结论是，松散土 质或砂子中的高硬度耐磨性可以与低YS/UTS结合以 产生良好的气刨耐磨性。这种改进作用原理是快速的 加工硬化速度可能会减少磨痕的切削深度，从而在每 次磨削过程中，需要去除的材料量较小。 Ni在改善所测试材料的磨损性能中的作用似乎是降 低屈服强度，使YS/UTS比较小，即当Ni的含量增加 时，加工硬度更大。实验体的硬度低于本研究测试的 三种合金。如前所述，较软的实验体可能会产生更显 著的磨损，这是由于砂石在实验体上粘附并滚动，增 加了测试钢材对砂石的接触和摩擦。Mn-C固溶体的 缺陷对第一阶段回火马氏体钢的加工硬化的影响仍然 是推测性的，但所得结果优于具有相似Ni含量的淬火 和回火钢。基础成份钢的较高磨损率可能与孔隙率和 II型硫化物的存在有关。 通过提高加工硬化速率改善淬火和回火钢的刨削耐 磨性，其特点是屈服强度与极限拉伸强度呈现低比率 （<0.8）。本研究中生产的合金是普遍适用的土方作 业设备的极好的选择，使松散或沙质土壤中的双体耐 磨硬度和对破碎和与破碎相关的抗刨磨冲击力的硬度 较强。本研究中的合金材料尚未经过优化，但对于生 产具有改进性能的新型钢材是一个好的开始。 ■ 本文根据美国铸造协会在亚特兰大举办的2019美国铸造大 会上发表的10-045论文改编。

Optimizing the Design Process Saves Precious Time in Mass Production Toyota Motor Corporation uses software to better diecast parts.

设计过程的优化帮助节省宝贵的批量生产时间

T

oday’s challenges of the automotive industry are short product development cycles along with resource efficiency and profitability. At the same time, desired or necessary design changes to products and components should still be feasible as late as possible in the development process to keep the required flexibility.

Especially for the mass production process of aluminum diecasting, used at Toyota Motor Corporation for various highly complex components, these changes lead to timeconsuming and cost-intensive modifications of the valuable production tools and process layout.

To overcome this conflict, the engineers of Toyota Motor Corporation strive to move from a sequential to a concurrent development cycle of product and process design as well as production planning. The objective is to meet the partly contrary requirements at the earliest stage possible to minimize costly changes and prototyping efforts.

Examples for aluminum diecast parts at Toyota include engine blocks and suspension towers.

The application of virtual methods, such as casting process simulation, is key to assessing feasibility and potential manufacturing restrictions in the very beginning of and along the whole development and design process.

The aim is to realize a robust and cost-efficient casting process that incorporates the different demands of Design, Process Engineering, and Production at the same time. Therefore, the Toyota engineers successfully integrated the methodology of autonomous engineering with MAGMASOFT into their design process. The efficient identification of significant influencing variables on casting quality and profitability is only possible through methodical process analysis and systematic test planning.

Optimization saves precious working hours.

通过优化节省极其宝贵的工作时间

MASOFT. In this case, avoiding misruns for a robust castability and reducing air entrapment for quality reasons were the most important objectives. In order to reduce the time for preparation and calculation, a simplified simulation model was used according to the MAGMA APPROACH. A systematic assessment and comparison of the virtual trials using MAGMASOFT scatter charts clearly revealed the best solutions for the de- fined wall thicknesses and ingate designs. The quantitative comparison of all variants using statistical methods provides reliable results without subjective influences.

In this way misruns could be completely avoided upfront, as the optimized results could easily be found in the areas of a better range for filling and a better range for quality.

The application of MAGMASOFT autonomous engineering saved precious time in comparison to the conventional simulation process, as many manual tasks like 3-D geometry model- ling and meshing could be avoided completely.

With the reference of this example, Toyota engineers proved that in addition to identifying a robust design and manufacturing solution, the required investment in working hours during design could be reduced by 50%. This helped to significantly reduce lead time in the development process as a whole.

For Toyota, the methodology of MAGMASOFT autonomous engineering today supports a more comprehensive understanding of processes, providing quantitative information at early stages of product and process development securing reliable decision making. ■

Vesuvius is one of the really big global players. What are your highlights for the foundries at this show?

Vesuvius is proud to be a leading supplier of technology solutions for foundries through our brand FOSECO. We continuously invest into Research & Development to develop ever more advanced solutions that allow our customers to improve their products or processes.

We showcase 14 new technologies at GIFA 2019 which is evidence of our strong commitment to Research & Development and of our close customer relationships in developing new applications and solutions.

To name just a few examples: • In feeding systems, we will feature the new, patented range of FEEDEX K feeders alongside SCK (sleeve construction kit) modular feeders for large castings.

• The new HOLLOTEX Shroud filtration system application for large, high value steel castings offers unparalleled levels of inclusion removal and reoxidation reduction.

• Automotive coatings offering the highest levels of internal casting cavity cleanliness will be featured together with our Intelligent Coating Unit coating control system.

• Finally, for aluminum foundries, FOSECO will be promoting the latest generation of SMARTT Melt Treatment Stations and ENERTEK ISO crucibles that offer enhanced insulation and reduced power consumption.

Customers that are visiting our booth will be able to find about these and many other advanced technologies in our portfolio.

Foundries are facing major challenges and the global economy seems to be weakening. How do you see the current situation and which markets have the best development potential?

Foundries face cyclicality from their end-markets and international competition has intensified. However, the past year has been positive for many foundries (ferrous and nonferrous) given the strong economic development globally.

But yes, the global economy is currently softening, particularly in automotive. This of course presents a challenge to foundries, but we do not yet consider this situation worrying.

For example, some geographies as well as some segments, such as mining and agriculture – which drive high casting volumes – continue to grow. Nonetheless, there is uncertainty how the economy will evolve in light of the ongoing global trade conflicts.

However, in such environments, casting innovation becomes even more important to help sustain the business and increase competitiveness. Our latest innovations provide differentiating solutions that bring value to our customers and help them withstand potential headwinds.

Additive manufacturing is also becoming an increasingly important topic at GIFA. To what extent have foundries already embraced and integrated 3D printing equipment, and what contribution does your company make in this context?

维苏威集团是全球知名企业，在此次铸造展的展示亮 点是什么？ 维苏威很荣幸能够通过我们的品牌福士科而成为铸 造企业技术解决方案的领先供应商。我们不断投入研 发，开发更先进的解决方案，使我们的客户能够改进他 们的产品或工艺。 我们在GIFA 2019展示了14项新技术，这证明了我们 对研发的坚定承诺以及我们在开发新应用和解决方案方 面的密切客户关系。 举几个例子： • 在补缩系统中，对于大型铸件，我们将采用新的 专利系列FEEDEX K冒口和SCK（套管结构套件） 模块化冒口。 • 新型HOLLOTEX护罩过滤系统适用于大型高价值 铸钢件，具备无与伦比的夹杂物去除和再氧化降 低能力。 • 我们的智能涂层单元涂层控制系统将提供具有最 高内部铸腔清洁度的汽车涂层。 • 最后，对于铝铸造厂，福士科将推出最新一代的 SMARTT熔液处理站和ENERTEK ISO坩埚，以增 强绝缘性、降低功耗。 铸造厂面临重大挑战，全球经济似乎正在走弱。您如 何看待当前的情况以及您认为哪些市场具有最佳的发 展潜力？ 铸造企业的终端市场面临周期性，而且国际竞争加 剧。然而，鉴于全球经济的强劲发展，过去一年对许多 铸造厂（黑色和有色金属）都是积极的。 但是确实，全球经济目前正在走弱，特别是汽车行 业。这当然对铸造厂提出了挑战，但我们不认为目前的 情况是令人担忧的。例如，一些地区以及一些行业，如 采矿和农业正在推动铸件产量的增长。尽管如此，鉴于 持续的全球贸易冲突，全球经济走向仍存在不确定性。 然而，在这样的环境中，铸造创新对于帮助维持企 业业务和提高竞争力变得更加重要。我们最新的创新技 术提供了差异化解决方案，为客户创造价值，帮助他们 抵御潜在的风险。 增材制造也成为GIFA越来越重要的主题。目前，铸造 厂已经在多大程度上接受并采用了3D打印设备，贵公 司在这方面做出了哪些贡献？ 我们密切关注增材制造技术的不断进步。事实上， 增材制造技术已经广泛应用于铸件生产中：尽管不适用

We are monitoring the continuous advancements in additive manufacturing. In fact, additive manufacturing is already widely used in casting production: while not for high volume castings it is used to create moulds and cores and also for rapid prototyping.

Foundries are evaluating the benefits of 3D printing versus traditional manufacturing. In our view, both production routes will coexist alongside each but for high-volume castings, traditional castings will likely remain the most cost competitive route in the near future.

In Vesuvius, we monitor the needs of this segment and drive projects that use 3D printing in the development of new casting consumable technologies.

In Europe, climate change and the right approach to addressing it are a hot topic. How does Vesuvius view the problem?

Climate change is a global phenomenon that affects all businesses and every individual. We at Vesuvius consider climate change as a real and very serious issue.

The metals industry is energy intensive which drives CO2 emissions and, as a result, there is increasing pressure to improve this CO2 footprint.

Most importantly, Vesuvius’ contribution to reducing emissions and achieving the goals set by the Paris agreement will come from our products and services. Our products help improve the sustainability footprint of our customers’ production processes by increasing yields, reducing scrap, lowering energy consumption and improving the quality of their end products.

At the same time internally, Vesuvius has been working to reduce our emissions of greenhouse gases and energy consumption for many years. In the last 5 years, we reached our goals of 10 percent improvement. We are in the process of defining our targets for the next 5 years and continue to optimize our operations, focusing on maximizing the utilization of raw materials and recycling. For example, FOSECO’s new ENERTEK ISO crucible is designed to save energy in induction furnaces.

However, given the global nature climate change, we must tackle it at a global level. All measures taken have to ensure that foundries in Europe can continue to compete with non-European suppliers, which potentially have lower environmental standards in their respective region. ■

于大批量铸件生产，但可用于生产模具和型芯，还可 用于快速成型。 铸造厂正在评估3D打印与传统制造技术相比的优 势。我们认为，这两种生产方式将并存，但对于大批 量铸件，传统工艺在近期仍是最具成本竞争力的生产 方式。 维苏威集团关注着这一细分市场的需求，并推动在 新的铸造耗材技术开发中使用3D打印的项目。 在欧洲，气候变化问题已成为热点话题。维苏威集 团如何看待这个问题呢？ 气候变化是一个全球化问题，影响所有的企业和个 人。维苏威集团认为气候变化是一个非常严峻的现实 问题。 金属行业是能源密集型行业，增加CO2的排放，因 此，减少CO2排放的压力越来越大。 最重要的是，维苏威集团对减排和实现《巴黎协 定》设定的目标的贡献将来自于我们的产品和服务。 我们的产品可提高产量、减少废品，降低能耗并提高 最终产品的质量，从而有助于提高客户生产过程的可 持续性。 同时，在公司内部，维苏威集团多年来一直在努力 减少温室气体排放量和能源消耗。在过去的五年中， 我们达到了10％的减排目标。我们正在确定未来五年 的目标，并将继续优化我们的运营，重点是最大限度 地利用原材料和回收利用原材料。例如，福士科的新 型ENERTEK ISO坩埚旨在节省感应电炉的能源消耗。 但是，鉴于全球的气候变化问题，我们必须在全球 范围内应对。采取的所有措施必须确保欧洲的铸造厂 可以继续与非欧洲供应商竞争，因为欧洲以外的供应 商在各自地区的环保标准可能较低。 ■

Norican is a strong combination of knowledgeable people, a global network and an owner team I already enjoy working with. Combine this with the exciting developments that are taking hold across the group from digital connected technologies to simple engineering innovations – ideas truly are currency at Norican, which is why I didn’t need much time to think when the Norican opportunity was presented to me.

席执行官，再之前是 GEA Process Engineering 的总

What excites you about joining Norican Group?

对于加入诺瑞肯集团，哪些地方让您感到兴奋？

The pure potential. As a company that comprises the four technologies of DISA, Italpresse Gauss, StrikoWestofen and Wheelabrator, Norican has the breadth and depth to solve industry challenges. Our equipment offer combines to cover everything from melting and casting to part preparation and finishing everything focused in metal. Adding to this, each of the technologies is an industry leader in its own right, so the opportunity to inspire customers with the potential performance gains offered by equipment from across the group, is truly exciting.

I was also impressed by the groupwide approach to innovation and data usage, exemplified by the creation of Norican Digital. As such I believe the company’s future is even more exciting than its past.

Finally for me, the key ingredient to success is people, and here the teams across Norican wear their passion for innovation with pride and are genuinely committed to customers. Group success is about teamwork, shared values and speed. With these qualities in abundance I believe we have what it takes to succeed for ourselves and for our customers.

What approach will you bring to the business to ensure we continue improving and delivering leading equipment and excellent services to customers?

I am a big believer in empowerment and avoiding bureaucracy to maximize business speed. Speed is a culture. You cannot buy more time – it’s the ultimate scarce resource. In a company the size of Norican, you need structure and process to manage operations, so my focus will be devoted on ensuring all of these processes are as effective, connected and seamless as possible for the benefit of customers.

In business I also pride myself on being competitively paranoid and never taking a customer or a market position for granted. That’s why I am determined this business will extend its reputation as a leader in innovation, to continue fueling customer growth.

Lastly, I think it’s very important to be professionally humble and constructively dissatisfied – and to use these traits to improve… always. ■

entonite and pulverized coal are always used as greensand moulding bonding agent and anti-sticking sand material in greensand moulding, and Zhuyuansu [1] is a kind of moulding material which can replace bentonite and pulverized coal; it is a patent technology. It has the advantages of small addition amount, stable process performance, good appearance quality of castings under the same process conditions, obvious reduction of sand dropping and sticking defects, yield-improving and cost-saving. In particular, it is worth mentioning that there is no pulverized coal in moulding sand, in the process of casting molten iron, no air pollution brought by combustion of pulverized coal, no MgO brought by combustion of pulverized coal, or no MgS generated by the combination of S and Mg in pulverized coal. In terms of nodular cast iron, magnesium compounds are reduced, which plays a key role in improving the surface decaying graphite of nodular cast iron.

For the exhaust manifold used at high and low temperature, the risk of cracks in the exhaust manifold is reduced due to the reduction of graphite layer in the surface layer.

Raising of the question Since the use of wet sand moulding, Hengtong Casting had been using pulverized coal as anti-sticking material for wet sand moulding.Under the conditions at that time, pulverized coal has played a proper role in anti-sticking sand of castings. Taking Hengtong Casting’s production of 3613 as an example, in 2017, 322,211 pieces of 3,613 castings were produced and 3,033 sand-dropping wastes were produced, which ranked the firs in waste analysis of the sand-dropping wastes of castings. In order to reduce the waste rate of castings and improve product quality, it was imperative to reduce the waste of sand dropping and sticking.

The market has more stringent requirements for the appearance quality of castings, and also has higher requirements for our casting production units. In addition, sand mixing process is the Company’s largest source of pollution, pulverized coal is light and black; bentonite is light and white, in the process of storage, handling, adding and sand mixing, dust is flying fuill of the whole workshop, which is obvious to all in our company. With the increasingly stringent environmental requirements of the country, it is difficult for pulverized coal and bentonite to meet the requirements of casting production.

Practical production shows that, instead of adding new sand, collapsible resin coated sand is used to replace new sand. Because the residual inert resin film on the surface of

一项专利技术。它的加入量少，工艺性能稳定，在工艺 相同的条件下铸件外观质量好，掉砂、粘砂缺陷明显减 少，提高了成品率，节约了成本。特别值得一提的是型 砂中没有煤粉，铁液在浇注过程中，没有煤粉的燃烧而 带来的空气污染，也没有煤粉的燃烧而带来的MgO， 也没有煤粉中的S与Mg结合而产生的MgS。对于球墨 铸铁而言，镁的化合物减少了，对改善球墨铸铁表层衰 退石墨起到了关键的作用。对高低温状态下使用的排气 歧管，由于表层片墨层的减少，降低了排气歧管裂纹产 生的风险。

一 问题的提出 亨通铸造使用湿砂型造型以来，一直使用煤粉作为 湿砂型防粘砂材料。在当时的条件下，煤粉对铸件防粘 砂起到了应有的作用,以亨通铸造生产3613为例，2017 年全年共生产3613铸件322211支，掉砂废品3033支， 在废品分析中铸件掉砂废品排名第一，为降低铸件废品 率，提升产品质量，降低掉砂、粘砂废品势在必行。 市场对铸件外观质量的要求更为严格，也对我们生产 铸件单位提出更高的要求。另外混砂工序是公司最大的 污染源，煤粉质轻色黑；膨润土质轻白色，在存储、搬 运、添加及型砂混制过程中灰尘飞扬，充斥整个车间， 这在我们公司有目共睹，随着国家对环境的要求越来越 严，煤粉和膨润土很难适应现在铸造生产的要求。 实际生产表明：不加入新砂，用溃散覆膜砂代替新 砂，由于溃散覆膜砂表层残留的惰性树脂膜具有憎水性 消弱了与水化膜的结合强度，影响到了型砂的性能， 随着旧砂中覆膜砂数量的增加，型砂的热湿拉强度和表 面耐磨性降低；导致废品率上升；如加入新砂，势必要

collapsible resin coated sand has hydrophobicity, it weakens the bonding strength with hydration film and affects the properties of moulded sand. With the increase of the number of resin coated sand in used sand, the hot-wet tensile strength and surface wear resistance of moulding sand decrease, which leads to the increase of waste rate; if new sand is added, it is necessary to increase the amount of bentonite and pulverized coal, a part of used sand should be discharged regularly to keep the sand balance in the sand treatment system, which increases the production cost, and increases the amount of solid waste discharged in the casting process and pollutes the environment. Therefore, after the new moulding material is added, the toughness and moulding property of the moulding sand should be improved, the hot and wet tensile strength of the moulding sand, the sand-entrainment resistance and the surface wear resistance and the fluidity of the moulding sand should be improved; and on the premise of not reducing the wet compressive strength of the moulding sand; and on the premise of not reducing the wet compressive strength of moulding sand, the adverse effects of the addition of resin coated sand core on the properties of clay sand are eliminated, and the anti-sticking properties of moulding sand are enhanced

Enterprises need a new kind of moulding material to improve the toughness and moulding ability of moulding sand, increase the hot-wet tensile strength, sand-entrainment resistance and surface abrasion resistance of moulding sand, and the fluidity of moulding sand after addition; and on the premise of not reducing the wet compressive strength of moulding sand, the adverse effect of adding resin coated sand core on the properties of clay sand is eliminated, and the anti-sticking property of moulding sand is enhanced.

Benefiting from the introduction of experts from casting association, a new kind of moulding material — Zhuyuansu powder, has been put into market application. The Zhuyuansual powder is a Zhuyuansual clay green sand mixture additives which is developed on the basis of high quality sodium bentonite, high carbon sand-sticking-proof material, alpha starch and other organic materials.

旧砂以保持砂处理系统的砂量平衡，提高了生产成 本，同时还增加了铸造过程固体废弃物的排放量， 污染了环境。因此新的铸型材料加入后要改善型砂 的韧性和起模性，提高型砂的热湿拉强度，抗夹砂 能力和表面耐磨性和型砂的流动性；在不降低型砂 湿压强度的前提下，消除覆膜砂砂芯加入对粘土砂 性能的不利影响，并增强型砂的抗粘砂性能。 二．铸元素粉特点、技术指标及使用方法对含大 量覆膜砂的型砂性能的影响 企业需要一种新的铸型材料，在加入后要改善型 砂的韧性和起模性，提高型砂的热湿拉强度，抗夹 砂能力和表面耐磨性和型砂的流动性；在不降低型 砂湿压强度的前提下，消除覆膜砂砂芯加入对粘土 砂性能的不利影响，并增强型砂的抗粘砂性能。 得益与铸协专家的介绍，一种新的造型材料---铸 膨润土、高碳防粘砂材料、α淀粉及其他有机物质为 基础开发出了铸元素粘土湿型砂混合添加料。

铸元素粉特点： 1. 加入量比一般膨润土、煤粉总和减少一半左右。 2. 型砂韧性好，提高起模强度。 3. 流动性好，便于充型紧实。 4. 保存性好，防止风干失去强度，特别是热砂。 5. 水分加入量减少15-20%，可防止气孔的产生。 6. 旧砂含泥量减少，降低新砂加入量。新砂加入量 减少60%，含10%以下的芯砂可完全不加，保持 用砂量的平衡。 7. 有效的解决了大量使用覆膜砂、三乙胺砂给型砂 造成的脆性。

Characteristics of Zhuyuansual powder: 1. The addition of bentonite and pulverized coal is reduced by about half as much as that of ordinary bentonite and pulverized coal.

2. Molding sand has good toughness and improves the starting strength.

3. Good liquidity, easy to fill and compact.

4. Good preservation to prevent air-drying loss of strength, especially hot sand.

5. The addition of moisture content is reduced by 15-20%, which can prevent formation of pores.

6. The mud content of old sand is decreased and the addition of new sand is lowered. The addition of new sand can be reduced by 60% and core sand with less than 10% can be totally eliminated, thus maintaining the balance of the amount of sand used.

7. It effectively solves the brittleness of moulding sand caused by the extensive use of resin coated sand and triethylamine sand.

8. The surface finish of the castings is improved, and the defects of sand washing and scarring are eliminated.

9. It has good reusability and can keep low addition for a long time.

10. Dust and flue gas pollution during casting is reduced.

11. The discharging device of sand mixer can be reduced by one.

12. The open-box sand after casting is easy to disperse, which can simplify the crushing equipment.

13. No spontaneous combustion of pulverized coal, which eliminates potential safety hazards.

14. The overall cost is decreased by 10-15%.

Model and technical indexes Zhuyuansu model and technical indexes are shown in Table 1.

Use method 1. The existing sand treatment bentonite silo is used to store the Zhuyuansual powder; the original pulverized coal silo is used to store the bentonite, and the bentonite is used as a standby to solve the fluctuation caused by the strength of the moulding sand of different products and to adjust the strength fluctuation.

2. The original sand mixing process remains unchanged.

8. 铸件表面光洁度提高，消除了铸件冲砂、结疤缺 陷。 9. 复用性好，可长时间保持低加入量。 10.减少粉尘和浇注时烟气的污染。 11.混砂机卸料装置可减少一个。 12.浇注后开箱的砂块显著容易散落，可简化破碎设 备。 13.不产生煤粉的自燃现象，消除了安全隐患。 14.综合成本下降10-15%。 三 型号及技术指标

铸元素型号及技术指标 见表1。

四 使用方法 1. 使用现有的砂处理膨润土仓存放铸元素粉；原来的 煤粉仓存放膨润土，膨润土作为备用，以解决不同 产品铸件，对型砂强度引起的波动，用来调剂强度 的波动。 2. 原混砂工艺不变。 铸元素粉在型砂浇注过程中的作用如下： 1）铁液的高温作用，铸元素粉的有机纤维质产生 大量还原性气体，防止铁液被氧化并可使铁液表面的 氧化铁还原，减少金属氧化物和型砂进行化学反应的 可能性。型腔中还原性气体主要来自铸元素粉热解生 成的挥发分。 2）铸元素粉受热后的矿物质等开始软化，具有可 塑性。如果由开始软化至固化之间温度范围比较宽和 时间比较长，则可缓冲石英颗粒在改变温度区间受热 而形成的膨胀应力，从而可以减少用砂型受热膨胀而 产生的铸件夹砂缺陷。

The role of Zhuyuansual powder in the casting process of moulding sand is as follows: 1) To the high temperature effect of molten iron, the organic fibre of Zhuyuansual powder produces a large amount of reducing gas, which prevents the molten iron from being oxidized and can reduce the iron oxide on the surface of molten iron, thus reducing the possibility of chemical reaction between metal oxides and moulding sand. The reducing gas in the mould cavity mainly comes from the volatile matter produced by the pyrolysis of the Zhuyuansual powder.

2) After heating, the minerals of Zhuyuansual powder begin to soften and have plasticity. If the temperature range from softening to solidification is wide and the time is long, the expansion stress of quartz particles caused by heating in the changing temperature range can be buffered, thus the sand inclusion defect of castings caused by thermal expansion of sand moulds can be reduced.

3) The Zhuyuansu powder produces colloid after heating, and the volume expansion part of the colloid plugs the pore between the sand grains on the surface of the sand mould, which makes the molten iron difficult to penetrate.

Performance comparison of moulding sand before and after test In order to prevent the fluctuation of moulding sand quality and the increase of casting waste, the original sand mixing process remains unchanged, as shown in Table 2 and Table 3.

Sand mixing process remains unchanged as shown in Table 2.

The properties of moulding sand before and after using Zhuyuansus are shown in Table 4.

From Table 1, Table 2 and Table 3, it can be seen that bentonite and pulverized coal in moulding sand can be replaced by Zhuyuansus, under the situation without adding new sand (our Company’s original sand mixing process did not add new sand), comparing the moulding sand mixed by clay used sand containing a large amount of resin coated sand core with the moulding sand mixed with used sand, bentonite and pulverized coal under the same technological conditions, the wet compressive strength, air permeability and compactness are similar, and the hot-wet tensile strength is obviously improved, and it can be seen that the adoption of Zhuyuansus and clay moulding sand mixed by clay sand and used sand with a large amount of resin coated sand core can eliminate the adverse effects of a large number of resin coated sand core on the properties of the sand.

ally implemented to replace bentonite and pulverized coal in moulding sand system. In order to ensure the normal production and avoid the large fluctuation of moulding sand performance to lead to the generaton of batches of waste, we adopt the method that adding Zhuyuansus on the basis of the original bentonite and pulverized coal green moulding clay used sand, in the working process, gradually replacing bentonite and pulverized coal in used sand by Zhuyuansus, and after a period of circulation, bentonite and pulverized coal in used sand are completely replaced by Zhuyuansus. The blending ratio and properties of moulding sand during the transition period are shown in Tables 4 and 5.

During the use of Zhuyuansual powder, the precondition of adjusting the addition of Zhuyuansual powder is that there is no big fluctuation in the test results of sand. According to the size of casting and the difference of drawing, the addition of Zhuyuansual powder and bentonite can be adjusted in time, and the produced castings shall be inspected in time, the appearance of casting and the waste products shall be inspected, so as to prevent the emergence of batch problems, resulting in waste of cost.

The properties of moulding sand in transition period is shown in Table 6.

after a certain period of circulation, which provides a basis for solving the problem of excessive graphite layer thickness of surface layer. Sodium bentonite and pulverized coal, and Zhuyuansual graphite layer are used to test the different parts for the same casting. Figure 7 sampling site.

Mechanisms of producing graphite layer: because of the contact between Mg and O in the air during the casting process of spheroidized molten iron, part of Mg will be oxidized to MgO. When molten iron is in contact with the mould wall, pulverized coal will burn. The combustion process of pulverized coal is also the oxidation process of Mg. Furthermore, S in pulverized coal will combine with Mg to form MgS, when the residual magnesium in the surface layer of molten iron is low enough not to ensure spheroidization, decaying graphite and graphite are produced, which is collectively called graphite layer.

In theory, graphite layer is unavoidable, but too thick graphite layer has a certain impact on product quality, especially in the exhaust manifold used under the alternating state of high and low temperature, cold and hot, graphite layer is the source of hot cracking. Figure14 is agraphite layer with a wall thickness of 4mm, and Figure 15 is a graphite layer allowed by Honeywell’s high nickel material. Therefore, each engine enterprise has certain regulations on the surface graphite of the exhaust manifold and turbine box. Generally, it is allowed to be between 0.2mm and 0.3mm, or even less than 0.15mm. It is very difficult to meet this requirement in technology. The oxidation

气歧管，涡轮箱的表层片墨都有一定的规定，一般 允许在0.2～0.3mm之间，甚至要求小于0.15mm。 达到这个要求工艺上是有很大难度的。在《汽车排 气系统用耐热材料的抗氧化性能研究》［2］一文中 对耐热材料的抗氧化性能做了详尽的研究，那么铸 造过程产生的表层氧化层（即片墨层）是高低温下 使用的排气歧管和涡轮箱的热裂源。使用铸元素后 有效的减少了片墨层的厚度，这是一个了不起的成 果。图14已经明显的能观察到片墨的存在，图15的 表层已经完全是氧化层而几乎看不到石墨。在使用 铸元素的金相图片中（图8、图10、图12）铸件表 层没有片墨，甚至看不到衰退石墨。表7检测结果

resistance of heat-resistant materials for automotive exhausting system is studied in detail in the paper of An Investigation on the Anti-oxidation Property of Heat-resisting Materials Used for Automotive Exhausting System [2], and then the surface oxide layer (i.e. graphite layer) produced during casting process is the hot crack source of exhaust manifold and turbine box used at high and low temperature. After use of Zhuyuansus, the thickness of the graphite layer is effectively reduced, which is a remarkable achievement. The presence of graphite has been clearly observed in Figure14, while the surface in Figure 15 is

completely oxidized and graphite is barely visible. In the metallographic pictures of Zhuyuansus (Figsure 8, 10 and 12), there is no graphite on the surface of the castings, and even no decaying graphite can be seen. The test results are shown in Table 7.

Cost saving, environmental improvement, reduction of solid waste discharge and rational utilization of storage space 1. The quantity reducing of added supplementary materials brought cost savings.

Taking Hengtong Casting sand mixing line as an example, 480 tons of moulding sand are mixed every day, the amount of pulverized coal that needs to be added is

本上效益显著，降低型砂成本。

2.废品的减少，带来效益的提高 使用铸元素粉前掉砂、多肉废品1.01%；使用铸 元素粉后掉砂、多肉废品为0.57%，提高了0.44% 带来效益的提高。按照年生产纲领100000支计算， 相当于减少4400支废品，每只扣除残值，可节约20 元，4400支可节约88000元。见表9。

3.降低了工人的劳动强度

45

480*0.6%=2.88 tons, and the amount of bentonite that needs to be added is 480*0.7%=3.36 tons. After Zhuyuansual powder is used, the addition is 480*0.7%=3.36 tons.

The cost-effectiveness of using Zhuyuansual powder to replace pulverized coal and bentonite is shown in table 8.

From the above table, it can be concluded that the replacement of pulverized coal and bentonite with Zhuyuansual powder has significant cost-effectiveness and reduces the cost of moulding sand.

2. Reduction of waste brought the improvement of benefit.

Before using Zhuyuansu powder, the sand dropping and fleshy Waste accounted for 1.01%; and after using Zhuyuansu powder the sand dropping and fleshy Waste accounted for 0.57%, improved by 0.44%, which brought the improvement of benefit. According to the annual production program of 100,000 units, it was equivalent to reducing 4,400 pieces of waste products, each deducting residual value, saving 20 yuan, and 4400

砂处理添加的辅料煤粉和膨润土在使用铸元素粉前 每天需添加6.2吨左右，在使用铸元素后每天只需添加 3.36吨左右的铸元素粉，1个月左右可减少2.88*25天 =72吨的加入量。

4.降低了固体废弃物的排放量，节约能源 使用铸元素粉前每天排放固体废弃物4吨，使用铸元 素粉后，砂处理整体粉尘减小，每天排放的固体废弃物 减少为2.4吨; 全月可减少1.6*25=40吨，降低了固体废 弃物的处理难度。 铸件外观粘砂少，清理过程产生的黑砂相应的减少， 可适当减少产品的抛丸时间，节约了部分动力消耗。

5.环境的改善

units can save 88,000 yuan. It is shown in Table 9.

铸元素粉与煤粉外观对比 （图16）：

3. Reduce the labor intensity of workers

铸元素粉外观为灰色，对环境的污染相对较小；

Before using Zhuyuansual powder, pulverized coal and bentonite as supplementary materials for sand treatment needed to be added about 6.2 tons per day, after using Zhuyuansual powder, it only needed to add about 3.36 tons of Zhuyuansual powder, and the addition amount can be reduced by 2.88*25 days = 72 tons per month or so.

煤粉外观为黑色，对环境的污染较大，高温下与

4. Reduce the discharge of solid waste and save energy Before using Zhuyuansual powder, four tons of solid waste are discharged every day , after using Zhuyuansual powder, the overall dust in sand treatment decreased, and the solid waste discharged per day decreased to 2.4 tons; and for the whole month, it can be reduced by 1.6*25=40 tons, which reduces the difficulty of solid waste treatment.

The castings appearance have less sticking sands, and the black sand produced in the cleaning process is reduced correspondingly, which can appropriately reduce the shot blasting time of the product and save part of the power consumption.

5. Improvement of the environment Appearance comparison between Zhuyuansual powder and pulverized coal (Figure 16): The appearance of Zhuyuansual powder is grey, and the pollution to environment is relatively small; The appearance of pulverized coal is black, which pollutes the environment greatly. The gas produced by the combination of pulverized coal and bentonite at high temperature is harmful to human body.

6. Reasonable utilization of storage space The original use of bentonite and pulverized coal requires a lot of space to store bentonite and pulverized coal respectively. After the use of cast elemental powder, it is only need half of the original storage space.

膨润土结合产生的气体对人体有害。

6.存储空间得到合理利用 原来使用膨润土和煤粉需要很大的空间分别存放 膨润土和煤粉，使用铸元素粉后，只需原有一半的 存储空间即可。

十.结论 综上所述，我公司作为生产铸铁的专业企业，湿 型造型为主要造型方式，旬阳日用型砂量达480余 吨，年产铸件100余万支，使用铸元素粉替代煤粉 和膨润土，从改善型砂性能、提高铸件质量、降低 生产成本、减少铸件废品率、净化工作环境等方面 都有显著效果。特别是使用大量溃散的覆膜砂，不 添加新砂的情况下，使用铸元素粉替代煤粉和膨润 土可有效改善型砂性能。片墨层的消除对于高低温 下使用的铸件更显意义重大。当然影响片墨层的因 素很多，需要方方面面都要有效的控制，才能生产 出优质的铸件。 需要说明一点，使用铸元素和膨润土+煤粉的可 行性比较，只能对同一产品，同样工艺使用前后做 对比试验，不同产品，不同工艺没有可比性。

Conclusion In summary, our Company, as a professional enterprise producing cast iron, takes green moulding as the main moulding method. The daily moulding sand volume in Xunyang is up to 480 tons, and the annual production of castings is more than 1 million pieces, With the use of castal element powder to replace pulverized coal and bentonite, significant results have been achieved in improving the properties of moulding sand, improving the quality of castings, reducing the production cost, reducing the waste rate of castings and purifying the working environment.

Especially when a large amount of collapsible resin coated sand is used and no new sand is added, the performance of moulding sand can be effectively improved by using Zhuyuansual powder to replace pulverized coal and bentonite. The elimination of graphite layer is of great significance to castings used at high and low temperatures. Of course, there are many factors affecting the graphite layer, which need effective control in all aspects to produce high quality castings. ■

Bürkert presents gas controls customized for a variety of casting plants Bürkert为不同的铸造厂定制气体控制系统 Industrial plants for producing steel for casting or for thermal processing technology place different requirements on their gas supply and rely on different automation concepts. Therefore, communication between components must always be tailored to the specific needs of the plant. Bürkert Fluid Control Systems is presenting a range of automation concepts for gas control based on its proven mass flow controllers (MFC). Possibilities range from data exchange through to “conventional” analogue standardized interfaces and digital networking using all common fieldbus protocols all the way to plug-and-play MFC assemblies, not to mention complete control cabinets including all components for gas control.

For smaller or simpler plants where only small amounts of data need to be transferred, the conventional analogue interface is the ideal choice. Start-up and maintenance are straightforward, and signals can be checked with the help of simple aids. These vendor-neutral devices operate independently of the controller and are extremely easy to replace. If diagnostic data, device state etc. are to be transmitted in addition to set-point and actual values, the mass flow controllers can communicate via digital interfaces, e.g. PROFINET, EtherNet/IP, PROFIBUS DP, Modbus TCP, EtherCAT, CANopen or RS485. Gateways and Bürkert’s proprietary büS network also allow the integration of other protocols - for gas-control functions that are fully compatible with Industry 4.0. Plug-and-play complete solutions, which can easily be connected to the higher-level controller for precise dosing and logging of gas volumes, can be realized with digital as well as analogue interfaces. The MFC assemblies and complete control cabinets are tailored to the application requirements. The entire fluid control layout is factory-tested, ensuring that installation and start-up can be completed easily and quickly on site.

In all automated gas-control solutions, the “Communicator” software simplifies the configuration, parameterization and diagnostics tasks. This practical EDIP tool (Efficient Device Integration Platform) is suitable for analogue and digital devices. It gives the user a complete overview of all cyclical process values as well as all acyclic diagnostic data.

Device configurations can be backed up and restored and the integrated, graphical programming environment makes it possible to create control functions for decentralized subsystems. Connections to a PC can also be established on the fly using a USB-CAN adapter. ■

在钢铁、铸造和热处理的生产过程中，根据要求不 同，使用不同的气体输送以及使用不同的自动控制系 统。因此，组件之间的通信必须始终根据工厂的特定需 求进行定制。Bürkert流体控制系统基于其成熟的质量 流量控制器（MFC），展示了一系列用于气体控制的 自动化概念。范围从数据交换到“传统”模拟标准化接 口和使用所有通用现场总线协议的数字网络，一直到即 插即用的MFC组件，还包括所有气体控制组件的总控 制柜。 对于只需要传输少量数据的小型或工艺简单的工 厂，传统的模拟接口是理想的选择。启动和维护非常 简单，可以借助简单的辅助工具检查信号。这些独立 于供应商的设备独立于控制器运行，非常容易更换。 如果除了设定点和实际值之外还要传输诊断数据，设 备状态等，则质量流量控制器可以通过数字接口进行 通信，例如，PROFINET，EtherNet/IP，PROFIBUS DP，Modbus TCP，EtherCAT，CANopen或RS485。 网关和Bürkert专有的büS网络还允许集成其他协议-用 于与工业4.0完全兼容的气体控制功能。即插即用的完 整解决方案可以通过数字和模拟接口实现，可以轻松连 接到更高级别的控制器，以实现精确计量和记录气体容 量。MFC组件和完整的控制柜根据应用要求量身定制。 整个流体控制布局经过工厂测试，确保可以在现场轻松 快速地完成安装和启动。 在所有自动化气体控制解决方案 中，“Communicator”软件简化了配置，参数设置 和诊断任务。这种实用的EDIP工具（高效设备集成平 台）适用于模拟和数字设备。它为用户提供了所有循环 过程值以及所有非循环诊断数据的完整概述。可以备份 和恢复设备配置，并且集成的图形编程环境可以为分散 的子系统创建控制功能。也可以使用USB-CAN适配器 即时建立与PC的连接。 ■

product news/产品新闻 railways sectors. Equipped with two DISA FLEX horizontal flask green sand molding lines and several DISA ARPA Jolt Squeeze molding machines, Nelcast’s flagship plant in Gudur produces 60,000 tons of ductile iron castings every year.

Nelcast was looking to find a better solution for managing the maintenance of its DISA FLEX 70 molding line with a goal to achieve best-in-class uptime and quality through an improved preventative and predictive maintenance. Rather than dedicate additional in-house resources, it wanted to partner with an expert to completely outsource regular servicing and spare parts support. Nelcast runs 24X6 and was looking for a partner who could not just commit resources but also take ownership of the task and approached DISA who they believed was uniquely qualified and committed.

DISA India proposed a service contract that would meet all of Nelcast’s needs. DISA would take complete ownership of the FLEX 70 molding line, from the sand plant and molding machine to the conveyer and dust collecting equipment. It would schedule and deliver all maintenance and make sure parts were changed at the right time as well as supporting in-house training, safety and process optimization.

Nelcast agreed and the new Service Contract – unique in the Indian market – was signed in November 2017.

DISA dedicated an experienced engineer to work full time in the Gudur plant to enhance equipment performance and availability and reduce downtime and lead time. Free of maintenance concerns, Nelcast could focus on managing its production.

Within a year, the DISA-managed line’s reliability increased sharply, and downtime dropped due to expert, regular maintenance and timely replacement of all necessary wear parts. With an objective measurement of performance and an incentive structure in the contract, the interests of Nelcast and DISA were perfectly aligned.

From improving mold hardness to reducing cycle time, DISA’s Service Contract enhanced every part of Nelcast’s process. Sand mixing and other delays were reduced or eliminated. With every part of the line and process working in harmony, maximum production increased from 84 to 93 molds per hour, quality improved and scrap dropped significantly.

With on-the-job DISA training, foundry staff learned optimum machine settings and efficient safe operation. A single point of contact and consistent monthly invoicing reduced administration for Nelcast and made maintenance costs predictable.

With better casting consistency, Nelcast rated DISA’s initiative as a “World Class” service offering and agreed a further Service Contract to manage its DISA FLEX 90 molding line in 2018. With growing demand from other clients, Service Contracts are now a standard part of DISA India’s Aftermarket offering. ■
