New DISAMATIC D5 completes foundry modernisation at LEDA 新款DISAMATIC D5完美成就了LEDA公司现代化铸造厂 High-end domestic stove and fireplace brand and foundry LEDA Werk GmbH & Co KG in Leer, Northern Germany, has commissioned a DISAMATIC D5 moulding line from DISA. It completes a programme of significant investment that saw LEDA’s foundry operations modernised from the ground up. It’s the first machine in the new DISAMATIC D5 range to be delivered to a customer.

Installation and commissioning were completed on schedule between December 2020 and January 2021, despite both the LEDA and DISA teams having to work around coronavirus lockdown and travel restrictions in Denmark and Germany.

About the foundry: highest quality in small series LEDA has been producing castings in Leer for nearly 150 years. Moulding equipment from DISA has long been a part of the LEDA success story, with the first DISAMATIC moulding machine beginning service in 1977.

The foundry mainly produces domestic fireplace and stove parts under its own brand, but also acts as a jobbing foundry covering a broad range of castings. Its strong commitment to the casting process even forms part of LEDA’s consumerfacing marketing, and the quality and standard of the casting process is a source of pride for the team in Leer.

That is why, over the last decade, LEDA has been in continuous modernisation mode, investing in new melting and sand mixing equipment, as well as replacing the smaller of its two moulding lines with a DISAMATIC D1 in 2019 and now the larger one with a DISAMATIC D5.

Folkmar Ukena, Managing Director at LEDA explains: “Efficient and high-quality casting production is key for us. We produce in small series, so we need moulding lines that deliver an extremely stable process despite multiple pattern changes per shift. DISAMATIC moulding lines deliver consistent, repeatable and high quality right from the first mould – exactly what we need.”

LEDA use the automatic core setter not just to place cores but also exothermic risers and filters.

德国北部利尔市的高端家用炉灶和壁炉制造商LEDA Werk GmbH & Co KG从迪砂采购了DISAMATIC D5造 型线。这是一个高明的决策，同时也是一项重大的投资计 划，使LEDA公司的铸造业务从一开始就实现了现代化。 这是首台交付给客户的全新DISAMATIC D5造型设备。 尽管LEDA团队和迪砂团队都不得不面对丹麦和德国的 新冠疫情引起的封锁和旅行限制，但安装和调试工作仍按 计划在2020年12月至2021年1月期间完成。

关于LEDA铸造厂：小批量、高品质 LEDA在利尔生产铸件已有近150年的历史。长期以 来，迪砂的成型设备一直是LEDA获得成功的一部分，第 一台DISAMATIC成型机于1977年投入使用。 该铸造厂主要生产自有品牌的家用壁炉和炉灶零件， 也包括更广泛的铸件生产、加工。公司对铸造工艺的坚 定承诺甚至构成LEDA以消费者为导向的营销组成，铸造 工艺的质量和标准是利尔团队的骄傲。 这就是为什么在过去十年中，LEDA持续进行着现代 化改造，投资于新的熔炼和混砂设备，并在2019年用 DISAMATIC D1替换了两条造型线中较小的一条，而现 在又用DISAMATIC D5替换了较大的一条。 Folkmar Ukena，LEDA营运总监说道：“高效和高 质量的铸件生产对我们来说至关重要。我们的生产规模 较小，所以我们需要造型线 提供非常稳定的工艺，即多 次更换型板。DISAMATIC 造型线从第一个铸型开始就 提供一致、可重复、高质量 的产品，这正是我们所需要 的。” 铸造厂经理Rochus Hiller 兴奋不已，他说：“通过这

INDUSTRY NEWS/行业新闻 LEDA Werk mainly produces domestic fireplace and stove parts like this one, but is also a jobbing foundry.

LEDA Werk主要生产家用壁炉和炉灶零 件，也是一家小批量的铸造厂。

Rochus Hiller, Foundry Manager, is thrilled: ”With this latest upgrade, we have now replaced all our vertical moulding machines with the latest D-series DISAMATICs and have future-proofed our processes.

The investment in new state-of-the-art equipment has enabled us to reduce our operating and maintenance costs, improve our energy costs and achieve high machine availability.”

次最新的升级改造，我们现在用最新的 D系列DISAMATIC造型机替换我们原有 的立式成型机，并使我们的工艺面向未 来。对最新最先进设备的投资使我们能 够降低运营和维护成本，降低能源消耗 并实现较高的机器利用率。”

About the new moulding line: efficiency in complexity LEDA’s DISAMATIC D5 is the latest in DISA’s flagship ‘D’ range of vertical moulding lines, which started with the D3 and its host of innovations which were then rolled out across the smaller and larger mould sizes with the D1 and D5 respectively.

The D5 replaces the old DISA 240 and 250 in the DISA range – and also at LEDA. The D5 range of three machines with mould sizes of 600 x 775mm, 600 x 850mm and 650 x 850mm achieves speeds of up 450 uncored moulds per hour.

Rochus Hiller comments on the upgrade: “The high degree of automation on the D1 and D5 offers us the features and settings to make more complex moulds efficiently. An example is adjustable squeeze distribution, a new feature we have not had before.”

Adjustable squeeze distribution ensures squeeze distances are optimised across the pattern, for swing plate and pressure plate, to adjust for asymmetric patterns or very deep pockets.

This achieves the most consistent and even moulds and the best mould surface. The result are castings with a great surface quality that require little extra finishing work or machining.

R. Hiller explains further: “Similarly, both the D1 and D5 have automatic core setters that enable us to produce more economical and save resources. We use the automatic core setter not just to place cores but also exothermic risers and filters. The efficiency gains we get through the higher level of automation and precision mean we maintain our competitive edge, but this also enables us to pass the benefits of more productive and sustainable production on to our customers.”

Sustainability is important to the team at LEDA, who had already introduced an energy management system across the foundry and are looking to reduce annual energy consumption continuously over time. The new moulding lines use less energy – directly and indirectly. Indirect energy savings are made through the avoidance of scrap and highly accurate castings that require minimal finishing work, but also through short cycle times, with less idle time between moulds required for core setting and other manual tasks.

And it’s not just energy that is being saved. For example, the new machines also use less hydraulic oil.

The new D5 at LEDA is a D5-Z which can produce up to 355 moulds per hour. This high speed, in addition to uncomplicated and fast pattern changes up to 30 times per day, gives LEDA the flexibility and responsiveness they need to 14

关于新造型线：高效率的实现复杂 造型 LEDA的DISAMATIC D5是迪砂旗舰“D”系列垂直造 型线中的最新款，该系列从D3开始，然后分别推出从较 小到较大模具的D1和D5。 D5取代了迪砂系列中原来的DISA 240和250，LEDA 也使用过。D5系列的三台机器的铸型尺寸分别为 600x775mm、600x850mm和650x850mm，可实现 速度为每小时处理450个无芯铸型。 Rochus Hiller针对此次升级表示：“D1和D5的高 度自动化为我们提供了高效制造更复杂模具的功能和设 置。例如可调节挤压分布，这是我们以前从未有过的新 功能。” 可调节的挤压分布可确保优化整个模具的挤压距离， 用于摆动板和压力板，以调整非对称模具或非常深的口 袋，以此实现最佳的一致性和均匀的模具，以及最好的 模具表面效果。结果是，铸件具有出色的表面质量，几 乎不需要额外的精加工或机加工。 R. Hiller进一步解释说：“同样，D1和D5都具有自动 下芯机，使我们能够更经济地生产并节省资源。我们使用 自动下芯机，不仅可以放置芯子，还可以放置发热冒口和 过滤器。我们通过更高水平的自动化和精度获得的效率提 升意味着我们保持了竞争优势，但这也使我们能够将更 具生产力和可持续性的生产优势传递给我们的客户。” 可持续性对LEDA的团队很重要，他们已经在整个铸 造工厂引入了能源管理系统，并希望随着时间的推移不 断降低每年的能源消耗。新造型线直接和间接使用更少 的能源。通过避免废料和需要最少精加工操作的高精度 铸件，以及通过较短的周期时间，减少下芯和其他手动 任务所需的模具之间的空闲时间，实现间接节能。节省 的不仅仅是能源，例如，新机器也使用较少的液压油。 LEDA采购的新D5是D5-Z，每小时最多可生产355个 模具。除了每天30多次的简单和快速换模具之外，高速 还为LEDA提供了他们所需的灵活性和响应能力，高效地 进行小批量生产，适合于一周5 天、每天2班次的操作。

利尔铸造车间：在充满挑战的环境中平稳转换

Pit stop in Leer: a smooth transition in challenging circumstances

被新的D5取代。尽管德国实施了本地封锁和旅行限制，

LEDA’s old DISA 250-C was replaced by the new D5 between the middle of December 2020 and the start of the new year. Despite a local lockdown and travel restrictions in Germany, a joint team comprising LEDA and DISA, plus transport and crane suppliers worked in shifts to deliver a smooth transition from old to new.

In the end, the meticulously planned changeover happened super-fast and exactly on schedule – despite the numerous challenges the pandemic brought – but not without nail-biting moments. Would the DISA team be allowed to travel into Germany from Denmark? Would hotels be open for them to stay in?

Right to the last moment, the old DISA 250-C was still working reliably. Therefore, after it had been running for LEDA for 20 years, the moulding line was taken back to DISA for reconditioning, so it could continue its service in a new home.

One key part of the old machine, however, stayed in Leer.

The DISA team was able to reuse the existing synchronized belt conveyor (SBC) and rebuild it on site to work with the new automatic mould conveyor (AMC).

The new D5 was designed to slot straight into the gap left by a DISA 240 or 250 with key dimensions retained to enable an easy transition to the new technology, not just at LEDA. LEDA’s new D5 produced its first mould on the 31th of December and started normal production on the 4th of January 2021.

R. Hiller on the milestone: “We are proud to welcome the second of our two new DISAMATIC moulding lines into the LEDA family. Both are at the heart of our production and will ensure the highest quality castings are delivered reliably and responsively for our customers.”

Ready for what’s next With LEDA’s strong focus on innovation, it was important to the team that any new equipment was digitally enabled and ready for Industry 4.0. The digital capabilities that come as standard with the two DISAMATICs mean LEDA can continue its digital journey seamlessly and is ready for the future.

F. Ukena concludes: “Digitalisation is an important tool in the continuous improvement of our products and processes. It’s therefore important to us to capture the digital state of the art when we buy any new equipment. DISA moulding lines are digitally enabled, allowing us to introduce digital tools in a way and at a pace that suits us.”

“For us, that means combining digitalisation with the incredible wealth of knowledge and experience we’ve got in our workforce. That’s the winning formula for staying ahead of the competition as a foundry in Germany.” ■ For more information on the new DISAMATIC D5, please visit: https://www.disagroup.com/en-us/d5

LEDA的旧DISA 250-C在2020年12月中旬至2021年初 但由LEDA、迪砂以及运输和起重机供应商组成的联合团 队轮班工作，实现了新旧设备的平稳过渡。 最终，精心设计的设备转换进行的非常快且准时—— 但是由于新冠疫情大流行带来了很多挑战，也有令人痛 苦的时刻。例如，是否允许迪砂团队从丹麦前往德国？ 酒店允许他们入住吗？ 直到最后一刻，旧的DISA 250-C仍在正常工作。LEDA 使用了20年后，该造型线被退回到迪砂进行翻新，以便 在新工厂继续服务。 然而，旧机器的一个关键部件留在了利尔。迪砂团队 能够重复使用现有的同步带式传输机(SBC)并在现场重 建，以与新的自动模具传输机(AMC)配合使用。 LEDA在2020年12月中旬到2021年初的这段时间里， 将旧的DISA 250-C替换为全新DISAMATIC D5垂直造型 线。新一代的D5造型线设计旨在直接填补DISA240或 250所留下的缺口，保留住关键尺寸，使客户能够轻松 过渡到新的技术，这不仅仅只是针对LEDA。 LEDA的这台全新D5造型线于2020年12月31日生产 了第一个铸型，在2021年1月4日就开始全面投入正常 生产。 R. Hiller发表了重要看法：“我们很自豪地欢迎我们的 第二条迪砂的全新DISAMATIC造型线进入LEDA家族。这 两条造型线都是我们生产的核心，随时能够确保为我们的 客户可靠和及时地交付最高质量的铸件。”

为下一步做好准备 LEDA非常注重创新，新设备实现数字化并为工业4.0 做好准备对其团队来说非常重要。两条DISAMATIC造型 线标配的数字化功能意味着LEDA可以无缝地继续其数字 化旅程，并为未来做好准备。 F. Ukena总结道：“数字化是持续改进我们的产品和 工艺的重要工具。因此，当我们购买任何新设备时，发 掘最先进的数字技术对我们来说很重要。迪砂造型线实 现了数字化，使我们能够以适合的方式和速度引入数字 化工具。” “对我们来说，这意味着将数字化与我们员工队伍中 的丰富知识和经验相结合。这是德国铸造企业在竞争中 保持领先地位的制胜法宝。”

any metallic components used in applications involving exposure to corrosive aqueous and atmospheric conditions suffer from degradation of the surface, such as corrosion and wear. These problems are especially widespread for castings used in the water supply industry, including pumps, butterfly valves, valve seats, faucets and flanges. To prevent corrosion on the surface of these components, water industries rely on coatings or specify cast stainless steel components. The oxide layer formed on the surface of stainlesssteel acts as a protective barrier between the environment and the sample surface.

Over the years, various techniques have been used to develop surface alloy coatings on steel to improve properties like corrosion and wear; however, these techniques are costly and often it is not feasible to use these coating methods on complex-shaped, hollow components—especially where there is no line of sight.

Because corrosion is a surface phenomenon, mainly the Fig 1. Butterfly valve molds for industrial casting (a,c): Bare and cleaned surface coated with zircon; (b,d): Multielement powder-coated mold surface using sodium polyacrylate.

surface of a component needs to be corrosion resistant. Thus, if the internal piece, or core, is made of a different material but the outside surface layer provides sufficient corrosion resistance, the component can perform at a level similar to a high corrosion-resistant component. This is also true for high wear-resistant applications in which a higher hardness coating will lead to high wear resistance even when the core is a softer material.

Cast surface alloying is a good solution to impart high local wear and corrosion resistance to cheaper and common industrial materials like mild steel. Some of the main characteristics of surface alloying during casting include: (1) the surface properties of materials and parts can be tailored to specific requirements (resistance against corrosion, wear, oxidation); (2) the alloyed layer is metallurgically bonded to the base metal; and (3) surface finish can be controlled, and machining allowance can be provided. Ni and Cr are frequently used alloying elements for improving the performance of wear-resistance, corrosion-resistance and thermal-resistance in iron-based components. Ni can dramatically improve the chemical stability of the iron alloys for increased corrosion resistance, and Cr leads to the formation of an oxide layer, which is highly protective against a corrosion reaction.

In the present study, targeted, multielement Ni, Cr, Fe-Mn, Fe-Si, and Mo enriched surface alloyed layers were developed and tested for a WCB steel butterfly valve on an industrial scale using the gravity sand casting process. A butterfly valve is a quarter-turn rotational motion valve, which is used to stop, regulate and start the flow. The alloying elements were picked for their presence in super duplex stainless steel components, which have very high corrosion resistance but are expensive.

具有足够的耐腐蚀性，则该部件可以在类似于高耐腐蚀 部件的环境下运行。对于高耐磨应用也是如此，即使芯 部是较软的材料，更高硬度的涂层也会具有高耐磨性。 铸件表面合金化是一种很好的解决方案，可以为低 碳钢等较便宜的普通工业材料赋予较高的局部磨损和 耐腐蚀性。铸造过程中表面合金化的一些主要特性包 括：(1)材料和零件的表面特性可以根据特定要求进行定 制（抗腐蚀、耐磨、抗氧化）；(2)合金层与母材冶金结 合；(3)表面光洁度可控，可提供加工余量。Ni和Cr是 常用的合金元素，用于提高铁基铸件的耐磨、耐腐蚀和 耐热性能。Ni可以显著提高铁合金的化学稳定性，以提 高耐腐蚀性，而Cr会导致形成氧化层，对腐蚀反应具有 很强的保护作用。 在本研究中，针对WCB钢蝶阀使用重力砂型铸造工 艺开发和测试了有针对性、Ni、Cr、Fe-Mn、Fe-Si和 Mo多元素富集的表面合金层。蝶阀是一种四分之一圈 旋转运动阀，用于停止、调节和启动流量。选择合金元 素是因为它们存在于超级双相不锈钢部件中，这些部件 具有非常高的耐腐蚀性，但价格昂贵。

All samples were in the as-cast condition.

(binder level ~1.2%) was used to ensure good gas permeability and surface finish during casting. The catalyst used was set to allow for an eight- to 10-minute work-strip time.

The sand and binder/catalyst chemicals were mixed in an industrial mixer and then dumped onto the pattern. The sand was manually smoothed, as well as with a strike-off bar, and allowed to set for 10 minutes. After the curing was complete and the mold halves were extracted from the pattern by flipping inversion of the pattern using a manipulator crane. The mold cavities were coated with a refractory wash to avoid any reaction between the molten metal and the sand. After applying binder and surface alloying elements on the mold and allowing the slurry to dry and harden, the molds were closed, and a zircon filter was placed in the down sprue of the mold.

Next, three samples were made using two different techniques. The first two samples were prepared by adding the Ni and Cr powders onto a wet refractory wash coating, and the third sample was made using a slurry containing Ni, Cr, Fe-Mn, Fe-Si, and Mo mixed with a sodium polyacrylate (NaPA) binder. Figure 2 shows a schematic representation of the sand mold before the WCB steel melt is poured. Once the mold surfaces were coated, they were sealed using a core and mold adhesive. The molds then were transported back to the industrial foundry for casting. Once the castings were poured, they were shaken out, shot blasted with steel shots, de-gated at the foundry and then transported back to the university lab for analysis.

The chemical composition of the WCB base alloy is presented in Table 1.

微观结构和相分析 表面合金铸态样品横截面的光学显微照片如图4所

Microstructural and Phase Analysis Optical micrographs of the cross-section of surface alloyed as-cast samples are shown in Fig. 4. A relatively uniform and continuous surface alloyed layer was observed in all samples.

Electro-etching of the surface alloyed layer was performed using an etchant made with 15% HCl and 85% Ethanol and passing a 2 Amp current using an electrode placed on the surface alloyed layer. The base metal (Fig. 6a) shows a ferrite and pearlite microstructure, which is typical of WCB steel.

Figure 6 (views b-d) demonstrates the cross-section macromorphology of the surface-alloyed layer, indicating a surface alloyed layer free of cracks or porosity. The interface layer between the base metal and the surface alloyed layer does not show the presence of cracks.

The microstructure at the interface of the surface alloyed layer and the base metal suggests a good metallurgical bond.

The microstructure in a typical surface alloyed layer (Fig. 6e) is composed of austenite (γ) phases in the shape of elongated islands dispersed in the ferritic (α) matrix and free of precipitates.

The EDS line scan results of surface alloyed sample BV3 (Fig. 7) shows the change in the gradient in compositions of various alloying elements from the substrate to the surface alloyed layer. Table 3 lists the composition of the surface-alloyed layer and the interface. Compared with the original composition of the WCB steel, significant increases in concentrations of nickel, chromium, Mo, Mn, and Si have been detected in a surface alloyed layer. The analyses were performed in regions ferrite (α phase) and austenite (γ phase) indicated in the micrographs (Fig. 6e). Chromium and molybdenum were observed in a higher percentage in the ferrite phase, since they are ferritizing elements, and nickel was present in a higher percentage in the austenite phase since it dissolves and stabilizes austenite.

The dissolution of alloying elements added to the slurry coated on molds leads to the formation of the surface alloyed layer. The weight percentages of Ni and Cr drop at the interface while that of Fe increases sharply as one moves from the surface

The base metal retains its α and pearlite phase microstructure, and the region immediately below the interface shows primarily an α phase with some pearlite.

XRD analysis of the surface alloyed layer of the surface alloyed sample BV3 confirmed the presence of ferrite, austenite and chromium oxide (Cr2O3) in the surface alloyed layer. The presence of Cr2O3 is known to improve the corrosion resistance of the alloy. This oxide can form in ambient conditions; however, heat treatment of the alloy leads to the acceleration of the formation of oxide.

Hardness Measurements

集表面合金层导致表面合金层硬度增加。其他研究人

The hardness of the surface alloyed layer and the base metal in the as-cast condition was measured using the Vicker’s microhardness test. The enrichment of the surface alloyed layer by alloying elements Ni, Cr, Mn, Si, and Mo led to an increase in the hardness of the surface alloyed layer. It has been previously reported by other researchers that the addition of Mo, Si, Cr throughout the section leads to an increase in the hardness, 0.2% proof stress, and tensile strength of the iron matrix.

The samples were tested in an as-cast condition, with each sample undergoing multiple measurements through the cross-section to ensure the average value is taken over the sample. The hardness measurements did not show any significant scatter within the surface alloyed layer, suggesting that the distribution of alloying elements in the surface alloyed layer is quite uniform.

表面合金化样品BV3的表面合金层的XRD分析结 果证实了表面合金层中存在铁素体、奥氏体和氧化铬 (Cr2O3)。已知Cr2O3的存在可以提高合金的耐腐蚀 性。这种氧化物可以在环境中形成；然而，合金的热 处理会加速氧化物的形成。

The corrosion resistance of iron-based alloys can be improved two ways: (1) improve its thermodynamic stability by adding some alloying elements with higher thermodynamic stability like Ni and Cr to the solid solution to increase its electrode potential and to decrease the anodic activation, and (2) promote the formation of stable passivation on the surface and improve its resistance on corrosion reaction by adding elements like Cr and Mo. Therefore, the large increases in the Ni and Cr content in the surface alloyed layers as a result of surface alloying can significantly improve its corrosion resistance.

In addition, the rise in austenite content in the microstructure of the alloyed layer will also improve the corrosion resistance. The fine microstructure as a result of relatively rapid solidification in the surface-alloyed layer can also decrease the corro-

Table 4 lists the corrosion rates of surface-alloyed butterfly valves samples and the base WCB steel. The heat-treated (normalized and tempered) surface alloyed sample shows a half corrosion rate compared to heat-treated (normalized and tempered) WCB steel. The base metal WCB steel has a higher pearlite content. Surface alloying and subsequent heat treatment transforms the microstructure to predominantly ferrite and austenite.

The as-cast microstructure of the surface alloyed layer showed the presence of intermetallic σ, which can be detrimental to the corrosion resistance of the surface alloyed layer.

The solution annealing treatment led to the dissolution of the intermetallic phase, as seen in Fig. 9, which is expected to improve the corrosion resistance of the surface alloyed layer.

Applications The novel cast surface alloying process in the study produced a surface alloyed layer enriched in several elements (including Ni Cr Mo Mn) on butterfly valve WCB steel sand castings. While the surface-alloyed WCB castings are slightly more expensive compared to WCB steel castings, they are much lower in cost than through section stainless steel (by as much as $10-$12 per lb.). The scalable and more economical techniques for coating sand molds and cores with a refractory wash containing metal and ferroalloy powder for surface alloying could include flowcoating, spray-coating, dipping and brush-coating.

This demonstrates the potential cost savings of using surface-alloyed WCB steels compared to through-section stainless steel components. It also demonstrates that surfacealloyed steel castings provide much more improved corrosion resistance, with only a marginal increase in the cost over plain WCB steel castings. This suggests several other potential applications of surface alloyed WCB castings in addition to butterfly valves, where corrosion and wear resistance higher than that of WCB steel are required. ■

高耐蚀性。由于表面合金层中相对快速凝固而产生的精 细微观结构也可以减少微电池效应引起的腐蚀。 表4列出了表面合金化蝶阀样品和基础WCB钢的腐蚀 速率。与热处理（正火和回火）WCB钢相比，热处理（ 正火和回火）表面合金样品显示出一半的腐蚀速率。母 材WCB钢珠光体含量较高。表面合金化和随后的热处理 将微观结构转变为主要是铁素体和奥氏体。 表面合金层的铸态显微组织显示存在金属间化合物 σ，这对表面合金层的耐腐蚀性是有害的。固溶退火处 理导致金属间相的溶解，如图9所示，这有望提高表面 合金层的耐腐蚀性。

应用 研究中的新型铸件表面合金化工艺在蝶阀WCB钢砂 铸件上产生了富含多种元素（包括Ni、Cr、Mo、Mn） 的表面合金层。虽然表面合金化WCB铸件比WCB钢铸 件稍贵，但它们的成本比通截面不锈钢低得多（每磅低 10-12美元）。用于表面合金化的含有金属和铁合金粉 末的耐火涂料涂覆在砂型和砂芯的技术包括流涂、喷 涂、浸涂和刷涂，这项技术可扩展，而且更经济。 这表明与全截面不锈钢部件相比，使用表面合金化 WCB钢具有潜在的成本节约优势。还表明，与普通 WCB 钢铸件相比，表面合金钢铸件具有更高的耐腐蚀 性能，成本仅略有增加。这表明除了蝶阀之外，表面合 金化WCB铸件还有其他几种潜在应用，这些应用需要有 比WCB钢更高的耐腐蚀性和耐磨性。 ■

Ask Chemicals Metallurgy Launches New Generation Of Inoculants 亚世科化学集团冶金分公司推出新一代孕育剂 Cut Inoculants With Tighter Tolerances And Higher Specificity The production of highly stressed castings places high demands on the inoculation technology and inoculants used.

With the new generation of cut inoculants, the company offers an improved solution characterized by tighter tolerances and higher specificity.

GERMALLOY C is used to improve the sphericity of the graphite and to optimize the mechanical properties of the casting. With OPTIGRAN C, casters achieve a finer, evenly distributed A-graphite in the gray iron.

Mold inoculation is the addition of inoculant as late as possible and hence also the inoculation method in which the fading effect is reduced to a minimum. This is particularly relevant for the production of thick-walled parts. In mold inoculation, the inoculant is introduced in the pouring basin or directly into the gating system of the mold. The dissolution therefore occurs under air exclusion directly in the iron over the entire pouring time. Casted inoculation blocks such as GERMALLOY C and OPTIGRAN C should be preferably used for mold inoculation, otherwise there is a risk of flowing in of non-dissolved inoculant grains with negative consequences for the cast structure.

While serial cast parts with normal wall thicknesses of 5 to 50 mm solidify in seconds up to a few minutes in casting production, the crystallization of thick-walled, heavy castings with wall thicknesses larger than 60 mm can take hours, depending on the casting temperature. A constant inoculation effect as offered by GERMALLOY C and OPTIGRAN C is important for a good casting result. The machined surfaces guarantee a good and uniform dissolution into casting.

Thanks to the close-tolerance manufacturing process, the inoculants have high dimensional, contour and weight accuracy and are therefore also suitable for robot-assisted handling and automatic insertion into the mold.

The dimensions of the inoculations are chosen in such a way that existing core markers can generally be used unchanged as placeholders for the inoculant inserts.

For larger requirements, it is also possible to deviate from the standard dimensions within certain limits. ■

更小公差，更高特性的切块孕育剂 高应力铸件的生产对孕育技术和所使用的孕育剂 提出了很高的要求。随着新一代的切割孕育剂，公司 提供了改进的解决方案，其特点是更小的公差和更高 的特性。 GERMALLOY C用于改善石墨的球形度和优化铸 件的力学性能。使用OPTIGRAN C，铸造厂可以在灰 铸铁中获得更精细、均匀分布的A型石墨。 型内孕育是尽可能晚地加入孕育剂，因此也是孕 育衰退降到最低的孕育方法。厚大零件的生产需要 特别注意这一点。在型内孕育中，孕育剂被放入浇口 杯或直接进入铸型的内浇口。因此，在整个浇注时 间内，孕育块在无空气接触下熔解。切块孕育块，如 GERMALLOY C和OPTIGRAN C，最好用于造型铸型 孕育，否则会有未溶解的孕育颗粒流入的风险，对铸 态组织结构造成负面后果。 而常规壁厚为5-50mm的系列铸件在铸造生产 中可在几秒钟至几分钟内凝固。GERMALLOY C和 OPTIGRAN C提供的持续孕育效果对良好的铸造效果 很重要。经过加工的表面保证了孕育块在铸件中良好 而均匀的熔解。 由于采用精密制造工艺，孕育剂具有较高的尺 寸、轮廓和重量精度，因此也适合机器人辅助操作和 自动插入型腔。 孕育块的尺寸是这样选择的：现有的砂芯标记位 置通常可以不变地用作孕育块的安放处。 对于较大孕育块的要求，也可能在一定范围内偏 离标准尺寸。 ■

product news/产品新闻 Fuji Electric’s intermediate frequency induction furnace was developed in 1963, and has gone through nearly 60 years history of intermediate frequency furnaces. IGBT series resonance intermediate frequency electric furnaces are developed based on the rapid development of its own semiconductor components IGBT and the advanced instantaneous control technology. Fuji Electric’s IGBT intermediate frequency induction heating furnace has the characteristics of energy saving, reliability and easy operation. It helps Fuji Electric IGBT intermediate frequency furnace to occupy nearly 70% of the Japanese market. It is widely praised by many customers in China, China Taiwan, South Korea, Southeast Asia and other regions.

Now, energy conservation, emission reduction and carbon reduction have become the development goals of the world.

The Chinese government has clearly set a long-term goal of carbon peak in 2030 and carbon neutrality by 2060.

The government has clearly pointed out at multiple levels that power devices, especially IGBTs, play an irreplaceable important role in the fields of energy saving and emission reduction, new energy, high-speed rail, as well as smart grids, and are the key “core” of a low-carbon economy. The development of IGBT technology is changing with each passing day. Fuji Electric began to produce the first generation of IGBTs in 1987 and now the seventh generation of IGBTs have come out, which are widely used in various fields of social development, making contributions to the development of the industry.

The advantages of Fuji’s intermediate frequency furnaces are:

1. Energy saving and fast melting speed Fuji’s proud IGBT power supply technology is different from the traditional thyristor power supply design in the intermediate frequency furnace industry, and it can meet the requirements of energy-saving, sensitive and high-efficiency.

The IGBT power supply can effectively improve the melting efficiency, thereby shortening the melting time and reducing energy consumption. Besides, Fuji intermediate frequency furnaces basically ensure that the coil height is equal to the rated metal level in the design to maximize the useful power and avoid the unnecessary loss caused by the “false coil” that only passes water but does not supply electricity; Fuji adopts a unique design with integrated coil, which is greatly increased, thereby improving the utilization efficiency; through techno-

一、节能、熔炼速度快 富士引以为傲的IGBT电源技术，区别于中频炉业内 传统的可控硅电源设计，更能实现节能且灵敏高效的要 求。IGBT电源的先进性可以有效的提高熔化效率，从 而缩短熔炼时间，降低能耗。其它如富士中频炉在设计 中基本保证线圈高度与额定金属液面持平，使有用功率 最大化，避免只通水不通电的“假线圈”带来的无谓损 耗；富士采用业内独有的一体型线圈设计，线圈密度大 大增加，从而提高了利用效率；通过技术革新，在安全 范围内尽量降低电流值，尽量避免热损等等。富士特有 的技术使得富士电机的中频感 应电炉在能耗方面处于领先水 平，每吨每小时耗电量比一般 高端电炉节能30~40度以上（ 变压器一次侧测量值），为用 户节省了用电开支。

二、稳定可靠 中频炉是集高压、高温、水 冷于一体的成套设备，风险性

product news/产品新闻 logical innovation, the current value is reduced as much as possible within a safe range, and the heat loss is avoided as much as possible. Fuji Electric’s unique technology makes its medium frequency induction furnace at a leading level in terms of energy consumption. The power consumption per ton per hour is 30-40 degrees more than that of ordinary high-end furnaces (measured on the primary side of the transformer), saving users electricity expenditure.

2. Stable and reliable Intermediate frequency furnace is a complete set of equipment that integrates high pressure, high temperature, and water cooling. The risk is high, so that safety is definitely the first priority for intermediate frequency furnace products. Fuji Electric has not only considered complete safety protection measures in all aspects, but even some environment elements other companies have ignored, Fuji Electric will not hesitate to respond. For example, Fuji Electric’s medium frequency induction furnace adopts world-class seismic design, and the maximum seismic rating has reached Level 7 on the Richter scale. In addition, it is also equipped with a sensitive anti-furnace leakage warning system. When the furnace lining has a risk of leakage, it can issue an early warning immediately to prevent major production accidents; when the electric furnace is tilted, it is equipped with anti-falling grid and pipeline protection device; it adopts parallel coil structure design, which enhances stability and prolongs the life of the furnace lining. The coil part adopts a dust-proof and moisture-proof coil design method, which is integrally formed, so there is no need to worry about condensation due to moisture and dust.

New Digital Tools Unlock Quick-Win Cost Savings For Blast Machine Operators 全新的数字化工具为抛丸设备操作员解锁快速致胜的节省成本技能 Wheelabrator has launched new digital tools that were developed specifically to help customers reduce cost around three key areas of the blast process: • abrasive consumption • energy use • maintenance and downtime The tools were built using Norican’s Monitizer software and NoriGate hardware, both already proven on equipment at sister companies DISA and StrikoWestofen, and are available for many existing and all new Wheelabrator machines.

Heinrich Dropmann, Senior Vice President Global Wheel at Wheelabrator, explains: “Digital technologies allow us to make the blast process more transparent than ever before and optimise it accordingly. We’ve been working with a select group of pilot customers to identify the applications that would make the biggest difference to their productivity and profitability and quickly zeroed in on these three.”

Tests showed that tackling abrasive consumption alone, using digital analysis and monitoring, can unlock €200-250 in annual savings per kilowatt blast power installed. For a typical hanger-type machine with four 11 kW blast wheels, this means up to €10,000 saved per year. Over the course of 20 years, savings generated by this one digital tool could pay for a new machine.

Heinrich continues: “The digital tools we’ve developed enable customers to really pinpoint the parameters that are driving abrasive consumption, energy use and wear in their specific operational setting – and then do something about it. They can very quickly get a much better handle on their blasting cost, without impacting the volume or quality of their outputs – or even improving them.”

The three tools can be deployed as standalone solutions or plugged into a wider Industry 4.0 system – be it from Norican, customer-built or from another supplier. The NoriGate data gateway is used to extract data from each machine – from the control system and from sensors – while the Monitizer software collects, visualises and analyses it in customizable dashboards.

Heinrich explains the Wheelabrator approach: “This is not about collecting data for the sake of it. As experts on the blast process, we can select the right data points to track, so we can combine them meaningfully and in a way that gives us insights into what’s running at optimum and what isn’t. It gives customers the data they need to continuously improve the process and save some money along the way.”

Reducing abrasive consumption – a significant cost factor Abrasive costs represent a major part of the overall running cost of a blast machine and the volume of abrasive going through the machine, relative to the blast result

维尔贝莱特推出了新型数字工具，专门用于帮助 客户降低抛丸工艺中三个关键领域的成本： • 丸料损耗 • 能源利用率 • 维护和停机时间 这些数字化工具使用诺瑞肯的Monitizer软件和 NoriGate硬件构建，这两者都已经在集团旗下姐妹 公司迪砂和史杰克西的设备上得到验证，并可用于 许多现有及所有新型维尔贝莱特设备。 维尔贝莱特全球抛丸高级副总裁Heinrich Dropmann说：“数字技术让我们能够使抛丸工艺比以往 任何时候都更加透明，并相应地对其进行优化。我 们一直在与一组精选的试点客户合作，以确定哪些 应用会对其生产力和盈利能力产生最大影响，并迅 速将注意力集中这三款应用上。” 测试表明，单独解决磨料损耗问题，使用数字分 析和监控，每千瓦抛丸功率，每年可以节省200250欧元。对于带有4个11kW抛丸设备的典型悬挂 式机器，这意味着每年最多可节省10,000欧元。在 20年的时间里，这个数字化工具节省的费用可以用 于购买新机器。 Heinrich 继续说道：“我们开发的数字工具使客 户能够真正确定在其特定运行环境中丸料损耗、能 源利用率和磨损的参数，然后采取相应措施。他们 可以非常迅速地更好地控制其抛丸成本，而不影响 其产量或质量。” 这三款工具可以作为独立的解决方案进行部署， 也可以插入到更广泛的工业4.0 系统中——无论是来 自诺瑞肯旗下品牌、客户自建还是来自其他供应商 的。NoriGate数据网关用于从每台设备（从控制系 统和传感器）提取数据，而 Monitizer软件则在可定 制的仪表板中收集、可视化和分析数据。 Heinrich继续说道：“这不是为了收集数据 而收集数据。作为抛丸工艺的专家，我们可以选择 正确的数据点进行跟踪，这样我们就可以将它们有 意义地结合起来，让我们洞悉哪些是以最佳状态运 行，哪些并没有以最佳状态运行。它为客户提供了 所需的数据，以不断改进工艺，并在此过程中节省 一些资金。”

product news/产品新闻 achieved, is a key determinant of wear inside the machine.

Using less abrasive to achieve the same blast result in the same time therefore is the holy grail of blast process optimisation.

And while modern blast machines have evolved considerably to improve this equation, real-time tracking and analysis of abrasive throughput and other process parameters can push this further. Yet again, this is not something that can easily be done without digital help.

Wheelabrator’s first new digital tool gives an accurate picture of abrasive use over time and relates it to other metrics, so root causes of high use can be identified quickly. Even complex or more subtle causes of increased abrasive throughput can be unpicked and resolved. The costs of monitoring and analysis are low compared to manual methods.

In numbers: For a hanger-type machine with four 11kW blast wheels, the tool helped reduce abrasive consumption (and spend!) by 17% and cycle time by 20%.

On a roller conveyor machine with six 15kW turbines, through-feed speed could be increased by 20% and abrasive spend reduced by 8%. Reducing or optimising abrasive consumption doesn’t just save money on abrasive, it also reduces energy use. Less wear means less maintenance and reduced spend on wear parts – by around 10%, according to Wheelabrator estimates.

减少丸料消耗——一个重要的成本因素

Saving energy – not as simple as it sounds

减少能源使用。维尔贝莱特预计，更少的磨损意味着维

Shot blast machines – wheel blast ones in particular – use a lot of energy due the power required to accelerate the abrasive. Bringing that energy consumption down while maintaining a stable blast process could unlock savings and support sustainability agendas.

However, most blast machine users do not and cannot currently record energy use of their machines alongside other process parameters to identify periods of high usage or unproductive time. Without this data, there is no way of improving a machine’s energy performance in a targeted way.

The second of the three digital tools from Wheelabrator does just that – it tracks the right parameters to strategically optimise standby and idle times, turbine rpms and more. This means operators and managers can instantly see if their machines are using unusually high amounts of energy, find the cause and tweak the process.

Over time, the running of the machine can be adapted for ever better energy efficiency without negatively affecting blast results or throughput (in fact, both may be improved as a side-effect of energy reduction efforts).

In numbers: Just by reducing idle time by 1 hour per day, the tool was able to unlock €14,000 annually in energy cost savings for a roller-conveyor machine with eight 45kW blast wheels. Doing the same on a less powerful pass-through monorail machine with eight 15kW blast wheels still achieved a saving of €4,000 per year. Both machines were operating in three shift 240 days per year.

护和磨损部件的支出减少约 10%。

丸料成本是抛丸机总体运行成本的主要部分，通 过抛丸机的丸料量相对于达到的抛丸效果，是决定抛丸 机内部磨损的关键因素。因此，使用较少的丸料在相同 的时间内达到同样的抛丸效果，是抛丸工艺优化的“圣 杯”。 虽然现代抛丸机的发展已经大大改进了这一方程式， 但对丸料产量和其他工艺参数的实时跟踪和分析，可以 进一步推动这一进程。然而，没有数字化的帮助，这不 是一件容易做到的事情。 维尔贝莱特的第一款新型数字工具，可以准确显示 丸料随时间推移的使用情况，并将其与其他指标联系起 来，因此可以快速确定高用量的根本原因。即使是复 杂或更微妙的原因导致丸料用量增加，也可以剖析和解 决。与手动操作相比，监测和分析的成本很低。 数据：对于带有4个11kW抛丸器的悬挂式机器，该 数字化工具帮助将磨料损耗（和花费）减少了17%，循 环时间减少了20%。在配备六个15kW涡轮机的滚筒输 送机上，通过进料速度可提高20%，磨料损耗减少8% 。减少或优化磨料损耗不仅可以节省磨料成本，还可以

节省能源——不像听起来那么简单 抛丸机（尤其是抛丸器）由于加速丸料所需的动力， 会消耗大量的能源。在保持稳定的抛丸工艺的同时降低 能源消耗，可以实现节约，并支持可持续发展议程。 然而，大多数抛丸机用户目前没有也不能将其设备的 能源使用情况与其他工艺参数一起记录下来，以确定高 使用率期间或非生产时间。没有这些数据，就无法有针 对性地提高设备的能源性能。 维尔贝莱特第二款数字工具中的第一款就可以实现这 一点——它跟踪正确的参数，以战略性地优化待机和闲 置时间、涡轮转速等等。这意味着操作人员和管理人员 可以立即看到其设备是否在使用异常高的能源，找到原 因并调整工艺。随着时间的推移，设备的运行可以适应 更高的能源效率，而不会对抛丸效果或产量产生负面影 响（事实上，这两者都可能可以作为节能工作的附带结 果而得到提升）。 数据：仅通过每天将闲置时间减少1小时，数字化 就能够为配备8个45kW抛丸机的滚筒输送机每年节省 14,000欧元的能源成本。在配备8个15kW抛丸机的功 率较小的直通式单轨设备上执行相同操作后，每年仍可 节省4,000欧元。两台机器实行每年240天，每天三班 的运行。

product news/产品新闻 Taming a violent beast – preventive maintenance Lastly, the inside of shot blast machines is a violent place. Wear comes with the territory. As with all equipment, keeping unplanned downtime to a minimum saves money and resources – as well as ensuring production targets and deadlines are met. Yet monitoring operating status and condition of a shot blast machine is still a manual, occasional process.

Here too, digital can help. By tracking things like turbine vibration levels, pressure differentials in filters and key performance metrics, Wheelabrator’s third digital tool can present a real-time picture of the machine condition and offer an early warning system for wear and drops in performance. This enables preventative maintenance at the optimum point, not too soon, not too late, preventing unscheduled downtime without overspending on parts.

In numbers: The tool helps prevent sudden or undetected parts failure, which causes expensive damage. For example, pre-empting blade breakage through early detection and timely, planned exchange cost €1,500 at a reference customer, whereas letting the blade break incurs costs of at least €4,500, depending on the extent of the damage. Blocked filters at one customer resulted in extra cost of €7,500 for clean-up and increased wear. An extreme example of a preventable fault are cracked filter cartridges, which allow fine dust to escape unnoticed and settle on surrounding machinery or even further afield.

On one occasion, ferrous dust damaged the paint on cars parked in an adjacent carpark. The cost for repainting exceeded €25,000.

It’s only the beginning The three tools were designed with quick payback for customers in mind, solving the most common issues and cost drivers machine owners are faced with. But these very specific applications are only the start of the journey.

NoriGate and the Monitizer platform are highly flexible, powerful and adaptable. What customers can do with the system can be evolved and expanded over time, with more tools and capabilities already in the pipeline, backed

by Norican’s commitment to digital innovation.

Heinrich concludes: “Customers who start collecting blast process data now, using one, two or all three of our new tools, are at the same time building up their digital database of historical data that can be analysed in new ways in future. So even if you want to take things slowly, you will have a wealth of data to learn from as new capabilities, like AI and automated process intervention, become available. It’s a highly sensible, pragmatic way of approaching all things digital. And if you’re ready for more straightaway, we invite you to get in touch, so we can show you what we’re working on!” ■ For more information on Monitizer please visit https://www.wheelabratorgroup. com/en-gb/equipment/digital-solutions/monitizer for more on Wheelabrator’s digital offering.

预防性维护 最后，抛丸机内部运行非常剧烈。磨损在所难免。与 所有设备一样，将计划外停机时间保持在最低限度，可 以节省资金和资源。然而，监测抛丸机的运行状态和条 件仍然是一个手动、偶发的过程。 在这方面，数字化也可以提供帮助。通过跟踪涡轮振 动水平、过滤器压差和关键性能指标，维尔贝莱特的第 三款数字工具可以实时呈现设备状况，并提供磨损和性 能下降早期预警系统。这样就可以在最佳时间点进行预 防性维护，不会太早，也不会太晚，防止计划外停机， 而不会在部件成本上超支。 数据：数字化工具有助于防止突发或未检测到的零件 故障，这会导致昂贵的损坏成本。例如，在推荐的客户 中，通过早期检测和及时、有计划的更换预防刀片破损 的成本为1,500欧元，而让刀片破损至少会产生4,500欧 元的成本，具体取决于损坏的程度。一位客户的过滤器 堵塞导致清理费用和损耗增加7,500欧元。可预防故障 的一个极端例子是破裂的过滤器滤芯，它会使细小的灰 尘在不被注意的情况下逸出并落在周围的机器上，甚至 更远的地方。有一次，铁粉尘损坏了停在相邻停车场的 汽车油漆。重新粉刷的费用超过了25,000欧元。

这仅仅只是开始... 这三款工具的设计考虑到了为客户提供快速的投资回 报，解决了设备所有者所面临的最常见问题和成本驱动 因素。但这些非常具体的应用只是旅程的开始。 NoriGate和Monitizer平台具有高度的灵活性，功 能强大，适应性强。在诺瑞肯对数字创新的承诺的支持 下，随着更多的工具和功能已经在开发之中，客户可以 利用该系统所做的事情可随着时间的推移而不断发展和 扩展。 Heinrich Dropmann总结道：“现在使用我们的一 款、两款或全部三款新型工具开始收集抛丸工艺数据的 客户，同时也在建立其历史数据的数字数据库，可以在 将来以新的方式进行分析。因此，即使您想慢慢来，随 着 AI 和自动化流程干预等新功能的出现，您也会有大 量的数据可供学习。数字化处理是一种非常明智、务 实的方式。如果您已经准备好马上开始，我们邀请您与 我们联系，这样我们就可以向您展示我们正在进行的工 作！”

product news/产品新闻 vehicles as well (e.g. AC compressors, steering systems …), the company is fully aware that projects for electromobility are important for the future, even though it is hard to say what the real share of electric vehicles in the following years will be.

Parts for independent heating have been in the company portfolio since 1996. In 2012, we started making prototypes of heat exchangers for electric independent heating for plug-in-hybrids and electric vehicles and went to serial production in 2015.

The Case Study A heat exchanger is made of two castings welded together by electron beam welding. Welding is made both by butt weld and overlap weld. For good heating efficiency, the heat-transmitting surface must be of perfect surface quality without any flow mark, etc. Finally, the whole assembly is leak tested by helium high pressure. To combine excellent inner quality with a perfect surface, a standard vacuum system is not enough.

Why the choice of fondarex as partner for vacuum?

That is the reason why KOVOLIS HEDVIKOV a.s. has decided to use the Fondarex HighVac Premium machines for this product. The measurement showed a considerable increase of vacuum level in the die, which was confirmed by CT scans, cuts, and finally by welding results. Transmitting surface quality has increased, and the problems with flow marks and small blisters disappear. Moreover, the Fondarex HighVac Premium machine offers very good process control and parameter check for process stability and repeatability. ■

零件的完全开发，包括有限元计算、原型制造和物理测 试，因此受到客户的赞赏。科沃利斯赫德维科夫公司 生产了大量用于内燃机车和电动汽车的零件（例如空调 压缩机、转向系统），但该公司充分意识到电动汽车项 目对未来很重要，尽管很难预测未来几年电动汽车的真 正份额是多少。 自1996年以来，独立的加热系统一直包含在公司产 品组合中。2012年，公司开始制造用于插电式混合动 力汽车和电动汽车的独立电加热热交换器的原型，并于 2015年开始批量生产。

案例研究 热交换器由两个铸件通过电子束焊接而成。焊接分为 对接焊和重叠焊接。为了获得良好的加热效率，传热表面 必须具有完美的表面质量，没有任何焊接流痕。最后，整 个组件通过氦高压进行泄漏测试。将卓越的内在品质与完 美的表面质量相结合，标准的真空系统是不够的。

为什么选择方达瑞作为真空系统合作伙伴？ 科沃利斯赫德维科夫公司决定采用方达瑞的HighVac Premium高真空系统。测量结果表明，模具中的 真空度显著增加，CT扫描、切割和焊接结果证实了这 一点。传输表面质量提高、流痕和小水泡问题消失。 此外，方达瑞HighVac Premium高压真空系统为工艺 稳定性和可重复性提供了非常好的过程控制和参数检 查。 ■
