Digital innovation is all around the steel The development of innovations in metallurgical technologies and plant engineering always leave certain questions unanswered. For example: How high is the mechanical load on the electrodes in electric arc furnaces during operation, i.e. during the power-on phase. What is known and can be observed during operation is that the electrodes are pushed towards the outside of the furnace. Such movements are caused by magnetic forces acting on the electrodes between the three phases of the current. It is also well known that such magnetic forces result in torques that can either fasten or loosen the threads of the electrodes and, in the worst case, the electrodes may break or even fall off. However, it has not been known so far, how these forces act in detail, what is their magnitude and the time dependency. The computation of the magnetic forces is complicated and has not been performed realistically to date. Now a realistic computation of the magnetic forces on electrodes and the steel bath in the EAF has been developed for the first time by German engineers who are presenting it in this issue.

Dipl.-Ing. Arnt Hannewald

The steel sector is keenly aware that today’s hot topics in business are Industry 4.0 and digitalization. In this scenario, German plant making company Schuler has developed Pipe ID 4.0 – a real-time process control system for large diameter spiral-welded pipe plants.

This comprehensive tool features a track and trace system, overall equipment efficiency monitoring, condition monitoring, smart diagnostics and power monitoring. The production data acquired includes all planned and unplanned downtimes including their causes, fault messages, target/actual production and the quality of the parts. In this way, the system operators gain a basis for calculating the overall equipment efficiency. Permanent logging of parameters also enables a cycle-accurate response in real time, where necessary; condition monitoring allows checking the system at regular intervals for damage and wear, and thanks to smart diagnostics, fault analysis is accelerated significantly. Even the coil storage area is managed in the database, which means that the coil data is assigned to the produced pipe. Mobile devices like tablets or smartphones can also be used for monitoring and evaluation.

The steel sector has reached the digital era, no doubt. Digitalization is part of almost every new investment project that MPT has been reporting about recently. Enjoy reading the news and technical articles in this issue.

Global steel demand continues its broad recovery The World Steel Association (worldsteel) released its April 2018 Short Range Outlook (SRO). worldsteel forecasts global steel demand will reach 1,616.1 million t in 2018, an increase of 1.8% over 2017. In 2019, it is forecast that global steel demand will grow by 0.7% to reach 1,626.7 million t.

Commenting on the outlook, Mr T.V. Narendran, Chairman of the worldsteel Economics Committee said, “In the next couple of years the global economic situation is expected to remain favourable with high confidence and strengthening recovery of investment levels in advanced economies. Benefitting from this, steel demand in both developed and developing economies is expected to show sustained growth momentum with risks relatively limited. However, possible adverse impact from rising trade tensions and the probable US and EU interest rate movements could erode this current momentum.�

Steel demand is benefitting from favourable global economic momentum, but facing risks from rising global trade tensions.

Upside and downside risks to this forecast are mostly balanced. In 2018, high confidence, strong investment levels and a recovery in commodity prices are generating a virtuous cycle for steel demand globally both in developed and developing economies. The slight deceleration in 2019 will be due to further deceleration in China and weakened investment momentum due to higher interest rates.

On the downside, possible escalation of trade tensions, rising inflationary pressure and tightening of US and EU monetary policies may cause financial market volatilities and trouble highly indebted emerging economies.

China will return to deceleration trend In 2017, the mild government stimulus measures provided some boost to construction activity, but investment World Steel Association (worldsteel), Brussels, Belgium Contact: www.worldsteel.org E-mail: steel@worldsteel.org

continued to decelerate and steel demand showed only a moderate increase despite the stimulus.

In 2018 and 2019 GDP growth is expected to decelerate mildly, but as the government continues to focus on shifting the growth driver toward consumption, investment is likely to further decelerate. Steel demand in 2018 is expected to stay flat. In 2019, it is expected to contract by 2.0% with a further slowdown in construction activity. In manufacturing, the machinery sector is expected to maintain positive growth on the back of a strong global economy while automotive and home appliances are expected to decelerate.

High corporate and local government debt continues to raise concern but a hard landing for the Chinese economy is unlikely in the short run.

Developed economies’ outlook remains robust Steel demand in the developed world is expected to increase by 1.8% in 2018 and decelerate to 1.1% in 2019.

The outlook for steel demand in the USA remains robust on the back of the strong economic fundamentals – strong consumption and investment due to high confidence, rising income and low interest rates. The manufacturing sector is being supported by a low dollar and increasing investment while rising housing prices and steady non-residential sector growth point to a healthy construction sector. Though the recent tax reform is further expected to boost steel demand through its positive impact on investment, there is some concern over a possible overheating of the economy. The announced infrastructure plan is unlikely to affect steel demand in the short term.

The EU economy has developed strong momentum with broadening recovery across countries. Prompted by robust domestic and external demand, investments are expected to remain a major growth driver while low inflation, wage and real income growth will support private consumption. Steel demand will be supported by a pickup in non-residential construction and strong manufacturing activities.

INTERNATIONAL INDUSTRY NEWS The automotive sector in both the EU and the US is expected to moderate due to saturation effect and rising interest rates, while the machinery sector is expected to benefit from rising investment. An expected monetary tightening in the US and the EU is responsible for the forecasted deceleration of steel demand growth in 2019.

Steel demand in Japan has been benefitting from an improving investment sentiment and government stimulus, but the scope of growth will continue to be limited by structural factors such as an aging population.

Despite improved consumer sentiment, steel demand growth in South Korea will be constrained by high consumer debts, weakening construction and a depressed shipbuilding sector.

Developing economies ride the recovery momentum, yet to gain further strength

Steel demand in emerging and developing economies (excl. China) is expected to increase by 4.9% and 4.5% in 2018 and 2019 respectively.

Recovery in oil and commodity prices has improved the outlook for MENA countries. Provided geopolitical stability can be achieved, steel demand outlook for the region could further improve as a result of reconstruction activities The mild recovery in Russia and Brazil is expected to continue. Recovery in Russia will be supported by credit expansion, easing monetary policy and improving consumer and business confidence. In early 2017 Brazil started to come out of its deep recession, but uncertainty remains as to the sustainability of this recovery momentum. Furthermore, recovery of construction activities has been slow. In other Latin American countries, recovery is also underway and growth in the region could accel-

erate if reforms are implemented, but the forthcoming elections lead to uncertainty.

Turkish steel demand showed strength in 2017, backed by supportive government measures. While slightly decelerating due to subsiding special economic stimulus, steel demand in Turkey is expected to show stable growth in 2018/19.

The Indian economy is stabilising from the impact of currency reform and the implementation of goods and service tax (GST). Steel demand is expected to accelerate gradually, mainly driven by public investment. Stronger growth is held back by still weak private investment.

Steel demand in ASEAN-5 countries dipped in 2017 due to slow construction activity and destocking. In 2018/19 however, steel demand is expected to regain the growth momentum backed by infrastructure investment.

We have always supported technology upgrade projects aimed at improving the quality of life not only for EVRAZ employees, but for all citizens of Nizhny Tagil. That is why this project got high-priority status in Sverdlovsk region,” - Governor of the Sverdlovsk Region Evgeniy Kuyvashev noted at the ceremony.

“We have built the new blast furnace at a record pace - in 18 months,” marked Managing Director of EVRAZ NTMK and EVRAZ KGOK Aleksey Kushnarev. “All labor-intensive operations of the furnace are automated. A powerful aspiration system entraps emissions during tapping.”

The new blast furnace of EVRAZ NTMK is the “cleanest” one in the Russian metallurgical industry. At hot metal tapping, emissions are trapped and impurities are removed in bag filters, to minimize atmospheric pollution. The degree of air purification has increased 2.5 times as compared to the operating furnaces.

The new blast furnace No. 7 at NTMK is again one of the ironmaking units with the highest productivity worldwide

performance of the entire blast furnace process at the plant both in terms of increased production and the reduction of costs. The number and duration of interim repairs will reduce; coke consumption will decrease by 5 kg/t as compared to the indicators of blast furnace No. 6.

Paul Wurth technologies in use in the new blast furnace In 2016, EVRAZ Group of Russia has decided to build this new blast furnace for developing and balancing their hot metal and steel capacities at EVRAZ NTMK, Nizhny Tagil. At hearth diameters of 9.8 m and inner volumes of 2,200 m³, with 22 tuyeres and 2 tapholes, each unit can produce 2.5 million tons of hot metal per year. Thus, the EVRAZ NTMK blast furnaces are some of the ironmaking units with the highest productivity worldwide. The new ironmaking plant configuration will allow full steel production even during periodical repairs of the one or other of the blast furnaces.

As per contracts concluded with EVRAZ NTMK, Paul Wurth has designed and supplied technology and

key equipment which will ensure reproducible operations and support a long campaign for No. 7 blast furnace.

This includes a parallel hopper Bell Less Top® charging system, tuyere stocks, the hearth refractory lining with a ceramic cup and two sets of fully hydraulic tapping machinery. As shown at NTMK’s No. 6 and No. 5 furnaces since 2004, vertical copper stave coolers in the highheat loaded bosh, belly and stack area will repeat their successful application in an evaporative cooling system. The BF top gas cleaning plant with axial cyclone and annular gap scrubber as well as Paul Wurth’s combined de-dusting system for stockhouse and casthouse ensure a minimum of environmental impact and a maximum of possible material return to the main process route.

With the aim of a record 18-month construction period, EVRAZ NTMK strictly followed a very tight overall project schedule which had to be matched by the systems and equipment suppliers. Paul Wurth’s international project team made it possible to fully satisfy the customer’s expectations in this regard.

Higher availability of the converter thanks to the AOD torque support developed by SMS group

Italian stainless steel company Acciaierie Valbruna S.p.A., Italy, was faced with the challenge of increasing maintenance efforts at the steelmaking plant at its steel works in Vicenza. Steel plant operators were observing uncontrolled vibrations of the gear unit and the AOD converter vessel during operation. The company decided to analyse the problem in more detail. SMS group was asked to examine the plant and develop a solu-

tion for a revamp. The targets were to increase converter availability and safety.

The 70-t AOD converter was monitored during operation using special sensors (accelerometers) which were connected to a measuring and data recording system. The measurements were performed in the presence of a specialist consultant from the University of Padua (Italy). According to the measurements and analyses, considerable destructive forces were acting on the gear unit, the bearings and foundation of the AOD converter during operation.

To overcome this problem, Acciaierie Valbruna awarded SMS group the order for the supply of a new torque support

for the converter vessel. Together with the Italian group company SMS INNSE S.p.A., SMS group supplied the torque support as a compact electro-hydraulic unit. The scope of supply also included the engineering and the supervision of installation. Both cold and hot commissioning were performed in close cooperation with the customer.

The consultant from the University of Padua made sure that the same method and the same components had been used for both measuring processes and subsequently confirmed the results. The target values under production conditions were achieved after a very short commissioning period.

Acciaierie Valbruna is fully satisfied with the results, especially in view of the increasing availability and higher production reliability of the AOD converter.

In addition, the maintenance effort for the gear unit will be drastically reduced.

The aim of the revamp – which was to minimize the destructive forces acting on the gear unit, the bearings and foundation during AOD converter operation – was fully achieved in every respect. What’s more, installing the new electro-hydraulic torque support has resulted in a substantial reduction in uncontrolled vibrations of the gear unit and the converter vessel.

Acciaierie Valbruna has three production locations – two in Italy, in Vicenza and Bolzano respectively, and one in Fort Wayne in the USA – as well as warehousing facilities at 40 sites around the globe. The company’s product range comprises around 700 different grades of special and stainless steel.

Magnetic forces on electrodes and steel bath in the EAF The computation of the magnetic forces on EAF electrodes and the steel bath is complicated and has not been performed realistically to date. Simulations have to be based on a proper geometrical model and need to consider that the current density in WKH KLJK FXUUHQW V\VWHP DQG LQ WKH VWHHO EDWK LV H[WUHPHO\ LQKRPRJHQHRXV )RU WKH ƂUVW time a realistic computation of the magnetic forces is presented in this article, applying the Finite Network Method computation system.

The Finite Network Method (FNM) computation system is a novel analytic tool for the simulation of electromagnetic phenomena of high current systems like those of electric arc furnaces. The FNM theory was created by Prof. A. Farschtschi and has been developed into a program system by BSE since 2015 [1 – 3].

FNM is the only appropriate tool for the magnetic field and force calculation of arc furnaces. The high current systems of EAF are subject to significant current displacement effects (skin and proximity effect) caused by eddy currents. Only if these effects are considered, can the magnetic field and the magnetic forces be computed realistically. Technically speaking, FNM generally solves the very complicated eddy current problem for arbitrary conductor geometries.

It is well known that the magnetic forces that act on the electrodes of EAF also result in torques that either fasten or loosen the threads of the electrodes.

This depends on the direction of the rotating field that is created by the three phase electric system. If the rotation is in the wrong direction, the electrodes may break easily or even fall off.

What is also known and can be observed during operation at every EAF is the impact of the forces on the electrodes. Electrode arms No. 1 and 3 are pushed outside (lateral movement) and the centre arm is pushed backward towards the transformer wall (pitch movement). The forces acting

FNM computed high current system of EAF No. 1 at Badische Stahlwerke GmbH, Germany (colours: current density, logarithmic scale)

between the three phases all repel each other because of different current directions. Conductors with equal current direction are pulled together. This attraction can be observed at the high current cable bundles of each phase.

What is not known is how the forces act in detail, i.e. their magnitude, direction and time dependency. The purpose of this article is to fill this gap and to describe these details by means of an exemplary FNM computation.

The system modelled here has been highly discretized in order to produce very accurate results for the forces. The FNM simulation results in the current density distribution of the high current system, i.e. a current density per volume element. A magnetic force is

acting on each volume element of the model that leads a current density.

Magnetic forces acting on the electrodes The FNM model has got the following parameters (sinusoidal conditions): ▪ current phase 1 (front): 59.5 kA ▪ current phase 2 (middle): 70.5 kA ▪ current phase 3 (back): 61.1 kA ▪ electrode diameter: 610 mm (24”) ▪ furnace inner diameter: 6.4 m (21’) Whether the currents are symmetrical or not has no qualitative influence on the computation result, i.e. on the directions of the magnetic forces. To indicate how the forces act on the electrodes, each one has been divided into eight equal volume

parts. This is important for comparability of the force magnitudes of each part.

It is interesting that the force is not constant in magnitude and direction over the length of an electrode.

The magnetic forces on the electrodes have got the following characteristic properties: ▪ The forces have got a static and a variable part. This is valid in the whole system.

▪ The static part has got a constant direction for given conditions.

▪ The variable part is rotating on an ellipse (for steady sinusoidal conditions) with double grid frequency.

▪ The force vector has got a maximum and a minimum magnitude which is defined by the constant part and the ellipse.

▪ Torques originating from the inhomogeneous current density distribution also exist. These try to rotate the electrodes around their vertical axes.

▪ The force ellipses along an electrode vertical axis do not lie in equal planes and have different sizes. This means that the forces along an electrode push in (slightly) different directions with different magnitudes.

▪ The force on the electrode tip volume part is directed upwards (the magnitude is between 200 and 470 N in this example).

The total forces on each complete electrode (below the holder) are computed assuming that the electrode is one long piece. The scale of current density has been changed to linear in order to indicate the large inhomogeneity of current density distribution inside the electrodes. The maximum and minimum force magnitudes of this example are: ▪ on electrode 1: 382 – 3,894 N ▪ on electrode 2: 296 – 4,796 N ▪ on electrode 3: 434 – 3,761 N

Magnetic forces on different volume parts of the electrodes (current density scale max. value: 1.3 A/mm²)

Total magnetic forces on complete electrodes, top view (linear scale of current density)

Magnetic forces acting on the steel bath Sometimes it is said that the steel bath rotates depending on the rotating field of the electrodes. It is known that the arcs rotate with double grid frequency at the tips of the electrodes

and that the magnetic forces push the arcs outside (deflection), causing the typical tip shape. The forces acting on the arcs are very similar to those acting on the electrodes.

It is also known that the arcs exert a pinch force on the steel bath, depressing it. A similar force acts in the volume part of the electrode tips and pushes these upwards. But what is the direction of magnetic forces on volume elements inside the steel bath? The computation result is that the magnetic forces in the steel act in a vertical direction and thus promote a vertical bath movement that supports the heat-induced movement. No horizontally acting magnetic force of significant magnitude can be found. This result matches the experience that high current short arcs (high forces) result in a better bath homogenization than low current long arcs (lower forces).

The forces have a significant magnitude only if the current density is high enough. The magnitude of the force on the highlighted surface volume element area (see figure) is 45 to 361 N. The centre area between the electrodes experiences the largest forces because here the electrode currents meet in the bath star point where i1 + i2 + i3 = 0 instantaneously. Compared to the electrodes, these forces are smaller by a factor of about 10 (one order of magnitude). The force on the same bath area but one layer (22 cm or 8.6”) deeper is already very small because there the current density is already very small: The magnitude of the force is 3.3 to 33 N. Due to the current displacement effects at grid frequency current flow in the steel bath is happening significantly only in the surface volume. The difference in current density between the two bath layers is already of an order of magnitude. Maximum value of the current density scale is 1 A/mm².

Current density in the surface of the bath

Conclusion BSE applies the FNM system for the optimized design of EAF high current systems. One important part of the design is the knowledge of the magnetic forces that appear during operational and short circuit conditions. FNM is the only analytic tool to date that allows realistic electromagnetic computations at EAF. MPT International 3 / 2018

The investment is also setting new standards in environmental protection. The centerpiece of the plant – an 60-t electric arc furnace which melts down ultra-pure scrap combined with various alloy metals into special steels – will be operated with electricity generated from renewable only. In addition, an efficient heat recovery system ensures that the heat generated during the process is used within the plant, as well as being fed into the public district heating network. In terms of cooling the production facilities, using closed circuits allows the volume of cooling water to be reduced by up to 90 percent.

The new steelmaking complex will comprise one melting hall and two casting halls. Robots will be used for the ingot casting operations.

The relevant development work and qualifying our employees in robotics, sensor technology, and data analysis takes place at our own digitalization competence center located directly on the site of the plant,” explains

The site preparations for construction of the new production facility, on an existing plot adjacent to the work’s premises which is around 50,000 m², have been underway since autumn 2017. This includes leveling the construction site, supplying the power in the form of two substations, and constructing access roads and assembly areas. The first contracts for hall construction and plant engineering are scheduled to be awarded this summer. Installation of the equipment is planned from 2019 onwards. The three-year construction phase will itself create up to 1,000 temporary jobs at the site.

After start of production in 2021, the fully digitalized plant will annually produce around 205,000 tons of sophisticated high-performance steels, especially for the international aviation and automotive industries as well as for the oil & gas sector, while at the same time securing more than 3,000 highly skilled jobs in the region over the long term.

ber 2017 as part of Tata Steel’s strategic investment in “Delivering our Future”.

A transfer bar cooling system has been installed which will increase the annual capacity of the site by around 5% and ensure steel can be quickly brought to the exact temperature required for the final product before it is rolled at the finishing mill stands.

Explaining why the transfer bar cooling system was needed, Mark Davies, Works Manager Hot Rolled Products, said: “The system is designed to cool steel to very specific temperatures, depending on what it is to be used for, rather than waiting for it to cool naturally. This fine temperature control also allows us to more tightly control the mechanical properties and surface quality of steel used in specific and demanding applications.”

Port Talbot produces high-quality steel which is processed at Tata Steel’s steel mills around the UK for manufacturers in Britain, mainland Europe and other countries around the world. Jon Ferriman, Tata Steel’s Director of Strip Products UK, said: “This investment has created a stronger, more efficient and more reliable platform from which we can meet the needs of our customers. We took the opportunity of a planned maintenance shutdown to upgrade several plant areas to further improve production of high-value steels and their delivery to customers.”

This is also true for the company’s latest innovation, Pipe ID 4.0 – a comprehensive process control system for the manufacturing of large pipes in real time featuring a track and trace system, overall equipment efficiency (OEE) monitoring, condition monitoring, smart diagnostics and power monitoring.

Schuler has already implemented machine monitoring in other production lines, e.g. for the manufacturing of railway wheels. The production data acquired includes all planned and unplanned downtimes including their causes, fault messages, target/actual production and the quality of the parts. In this way, the system operators gain a basis for calculating the OEE. Permanent logging of parameters also enables a cycle-accurate response

PIPE MAKING in real time, where necessary; condition monitoring allows checking the system at regular intervals for damage and wear, and thanks to smart diagnostics, fault analysis is accelerated significantly.

With large pipes, product data acquisition is of particular importance when it comes to inspecting the high grade steel pipes (X100) in accordance with the API 5L standard regarding dimension or welding quality by means of ultrasonics, hydrostatic testing and X-rays. Schuler upgraded the analog X-Ray system to a digital version, so it can be easily integrated into Pipe ID 4.0.

It includes a server station that stores the results of these tests as well as all of the other machine parameters.

With network label printers or paint marking and barcode scanners, all of the pipes in the plant can be traced and tracked, and their quality e.g. regarding close tolerances ensured. Even the coil storage area is managed in the database, which means that the coil data is assigned to the produced pipe. Mobile devices like tablets or smartphones can also be used for monitoring and evaluation.

Fiber optical network with ERP interface The server station also forms the backbone for the fiber optical network every

machine is connected to by managed industrial switches. This enables an overview of the workflow process including a quick status of the single machines and big pictures of the stations under work and with fault, the production time of single pipes and a fault report.

An interface to the customer ERP network is integrated.

Up to 50 operator terminals all over the plant grant access to information about the actual working time, the number of pipes per time unit, the production rates, the status of the plant and error messages of the working stations – like the offline welding station, the hydrostatic testing machine, the cross seam welding and repair stand, the inspection stand or the pipe end beveling machine. This reduces operation effort as well as costs for maintenance and repair.

Additionally, with its new robots for tab plate welding and cutting, final pipe measuring, grinding and pipe stenciling, Schuler developed a fully automatic system which can be used for both pipe ends. The minimum cycle time for dia– meters ranging from 20” to 88” is approximately five minutes. Short coil and diameter changing times, a high flexibility and low downtimes further increase the degree of automation that Schuler’s spiral pipe plants dispose of.

maintain tight flatness and thickness tolerances but also ensure a good quality surface. The compact design minimizes the out-of-tolerance strip thickness. The project was completed on schedule within 21 months.

Compact mill design for minimum off-gauge and maximum yield Primetals Technologies supplied the complete process equipment, electrics and automation from a single source, and was also responsible for supervising the installation and start-up of the plant. The cold rolling mill has a maximum roll separating force of 18,000 kN, and allows to produce strips with an entry thickness ranging from 0.7 to 2.0 mm down to exit thicknesses between 0.3 and 1.0 mm. The strip width ranges from 900 to 1,650 mm. The maximum coil weight is 32 metric tons.

The scope of supply from Primetals Technologies included the roll force cylinders – with integrated high resolu-

tion position transducers, low friction seal and guiding rod assembly – which form the key element in achieving precise thickness control. The cylinders and other core components were manufactured in the company’s own workshops, and thoroughly tested before delivery. The production of perfectly flats strips is ensured by advanced work roll bending, multizone cooling of the work rolls and continuous flatness measurements, combined with special technology packages, such as automatic flatness control. For strip blow-off, a special air-nozzle arrangement is used. The design ensures efficient blow-off at all rolling speeds thus contributing to a high surface quality of the rolled strip. The surface quality is further improved by using a Coil Eccentricity Compensator (CECO) model. CECO stabilizes the strip tension and ensures a consistent strip thickness by compensating for any eccentricities in the coil which may have been caused by the clamped head ends of the strips.

BTU Bridle Technology has received an order from SES Engineering covering the design, construction and supply of three Umlauf Bridles for a revamp of a push-pull pickle line at the Columbus, Mississippi (USA) site of SDI Flat Roll Group. SDI expects from the pickling line revamp in Columbus/Mississippi, for which SES acts as general contractor, above all a solution capable of producing very high strip tension in the line. Therefore SES chose the Umlauf Bridle technology from BTU. Thanks to their special design, Umlauf Bridles of the latest 3.0 generation are able to apply

much higher forces onto strip in processing lines than conventional bridle roll units. What is more, Umlauf Bridles distribute the strip tension extremely uniformly across the complete width of the strip. The bridles build up a strip tension high enough to ensure that also thick-gage and high-strength strip will leave the pickle line leveled.

The first of the three Umlauf Bridles will be arranged directly behind the pay-off reel. There it will immediately bite the very first centimeters of the head of the up to 13 mm thick and up to 1,880 mm wide strips and guide them into the stretch-leveler. (The stretch-leveler will be supplied by SES.) In connection with the second Umlauf Bridle arranged behind the leveler, strip tensions of up to 1,250 kN can be reached during stretch-leveling. A very intensive scale breaking ef-

fect will result from the thus achieved elongation rates of 0.5 to 1.0 percent.

This will make it possible to operate the line at speeds of up to 150 m/min. As the strip is actively pulled through the leveler by the Umlauf Bridle, no roller drive equipment is required in the leveler. This reduces investment and maintenance costs and prevents roller slipping.

The second Umlauf Bridle pushes the leveled strip into the pickling tank, and the third one will be arranged at the run-out to bite the head of the pickled strip and guide it into the recoiler. At the same time, it creates the strip tension needed to produce exactly wound coils.

Daniel Cullen, Senior Sales Manager of SES Engineering, explains the reasons for choosing the Umlauf Bridle technology: “The most important aspect for us was to find a technology that would be able to reach very high strip tension and allow us to control that strip tension in a very precise way. Apart from that, the simplicity of the Umlauf principle convinced us: we will be able to set the right strip tension exactly where in the line we need it – without any conventional bridle rolls, driven rollers in the leveler or an additional braking unit. Moreover, in future stretch-leveling will require less strain energy as there is no bending of strip in the Umlauf Bridles.”

According to Michael Umlauf, Commercial Manager of BTU Bridle Technology, by moving the strip exclusively in a linear way the Umlauf Bridles are superior to bridle rolls in several respects: “Using Umlauf Bridles in connection with stretch-levelers means that leveling is performed primarily by stretching and only to a minor degree by bending. Actually, up to 90 per-

STRIP PROCESSING cent of the leveling work comes from the stretching effect.�

The pickle line is scheduled to come back on stream after the revamp in January 2019.

The Umlauf principle Umlauf Bridles consist of two crawler-type units covered with an elastic coating. One unit is arranged above and one below the strip. They guide and transport the strip linearly, i.e. without any deflec-

strip head. This significantly increases the usable coil length, in other words the yield. In certain strip processing lines this may lead to a plus of 20 meters per coil.

Umlauf Bridles can be rotated very precisely through their vertical axis, for example, in order to reduce strip camber during leveling or adjust the strip position during side trimming. At cut-tolength lines, they position the strip edge perfectly perpendicular to the shear.

The advantages of this solution: perfectly rectangular cut-to-length strip.

winding of the strip and wind the strip with the correct tension. As Umlauf Bridles can be rotated through their vertical axis, the position of the strip in the recoiler can be adjusted within a tolerance of Âą 1 mm. Moreover, Umlauf Bridles are able to apply virtually any required tension onto the strip.

As Umlauf Bridles are able to apply very high tension in a precisely controlled way, it is possible to adjust the tensile and compressive forces as re-

tion, at different positions within strip processing lines. Thanks to their extreme compactness, they can be arranged at virtually any position in the line.

By applying the force over an area – and not concentrated in one point – any local concentrations of forces or relative movements between the crawler unit and the strip surface are prevented.

Therefore, the risk of surface damage is ruled out, making this technology highly suitable for delicate strip surfaces.

A single Bridle unit may be used to apply large forces to the strip, for example, in order to pull it through side trimmers, slitting shears or levelers. This aspect is of particular interest especially when processing thick strips. The unit may also be installed to decouple the strip tension of a line section from upstream processes or even reduce the strip tension to “zero�. By this means, an Umlauf Bridle makes it possible, for example, to measure the flatness of the strip without any interfering effects.

As the Umlauf Bridles are arranged within the strip processing line, they build up strip tension before the coiler bites the

Last but not least: perfectly wound coils Umlauf Bridles ensure high-precision strip steering and high strip tension to produce straight-edged, tightly wound coils. An exactly wound coil is an indicator of good quality.

The most critical aspects in strip coiling is to achieve straight-edged

quired within wide ranges. The extremely uniform distribution of the linear tensile forces also make for a better rolling result. Also, Umlauf Bridles perform other important functions along strip production and processing lines: They provide high process safety, increase the plant throughput and simplify the plant layout.

/QNBDRR ×THCR ENQ CDL@MCHMF LDS@KVNQJHMF applications FLUIDS TECHNOLOGY Manufacturing process fluids used in metalworking operations are challenged by the need to be high performing, compatible, and versatile. Quaker Chemical Corporation addresses these concerns in drawing and forming, hydroforming, and tube and pipe applications.

One such solution is the Quakerdraw® product line which encompasses a range of metal forming lubricants consisting of emulsifiables, neat oils, and solution synthetic fluids with a number of key benefits: superior lubrication to increase die and punch life; excellent corrosion protection; high film strength additives to reduce scratching and galling on parts and dies; easy to clean with solvent or alkaline cleaners. The products are compatible with typical waste water treatment processes and highly versatile in applications for light, medium, or heavy forming, roll forming, cold heading and hydroforming.

In instances where chlorinated paraffins are an issue, Quaker’s latest reformulated fluids offer the heavy duty performance without the chlorine content. These drawing and forming fluids can replace chlorinated forming lubricants on all metal types. To develop and test lubricant performance, Quaker utilizes the twist compression test, which simulates lubricant starvation conditions and tests boundary and extreme pressure lubrication regimes.

For tube and pipe applications, Quaker applies its “frontto-back” approach including not only a range of process fluids for the front end of pipe manufacturing, but also protective coatings to finish at the back end, coupled with the expertise to implement customized solutions for specific customer needs.

$MDQFX DEÖBHDMS SNQPTD CQHUDR ENQ LHWHMF TMHSR MATERIAL PROCESSING Permanent-magnet synchronous motors, which are also known as torque or high-torque motors, are rapidly becoming established as the standard solution for more and more applications – and now also in mixing technology from Eirich.

Mixing drives with asynchronous motors come with restrictions. Usually, the rotational speed of the motor is not the same as that of the mixing tool. In terms of its basic layout, a torque motor is the same as a conventional asynchronous motor. The key difference is in the design of the rotor. Instead of the armature found in an asynchronous motor, which is subject to slip, in torque motors rotors loaded with permanent magnets are used. This enables an increase in the size of the magnetic field by around

20%. The design of the rotor with permanent magnets and the resulting geometry lead to an increase in drive torque, which in turn allows the motor to be used as a direct drive.

There is virtually no wear at all in the motor, partly also because there are no radial belt forces. Further advantages of the torque drive result from the way in which the torque motor works and from the fact that it is operated with a frequency inverter as standard. Thanks to the high torque, which remains constant throughout the entire operating range of the motor, the torque drive with frequency inverter makes it possible to optimally adjust the rotating speed of the mixing tool to the requirements within a mixing process. Together with a high overload torque, the torque drive also enables the tool to start up under high loads.
