ADVERTISEMENTS: For obtaining extremely narrow thickness tolerances and good strip flatness, six-high roll mill is preferred because of the facility of positioning the intermediate rolls and also the facility for positive/negative bending of both the and intermediate rolls. For automation of such a mill, the electrical and hydraulic screw down equipment has to be

All data concerning Rolls can be directly retrieved both from the Roll Grinders and the Rolling Mill. Moreover, the system can collect data about grinding wheels, chocks and bearings. Thanks to this powerful database, the Roll Shop Manager will be able to view historic data, make performance statistics and create personalized reports.
Oct 01, 2003· Only by offering solutions, which are well integrated with the automation platform, the full improvement potential can be realized. ABB's latest development based on its new IndustrialIT automation platform and its advanced technology solutions for cold rolling mills lead the way into the future of rolling mill automation. REFERENCES ABB (2002).
Sep 26, 2020· The parameters considered during the manufacturing and during the regular use of rolls in cold rolling in the past researches and the effect of these parameters to increase the life of a roll.
Steel rolled in two-stand reversing cold mills is suitable for a wide range of applications, offering the best possible performance in terms of quality and productivity. A two-stand reversing cold mill can deliver capacities between 300,000 t/a of thin-gauge products
Technology and equipment for Cold Rolling Mills Tenova I2S is a recognized leader in technologies and innovative design and supply of cold rolling mills. Since 1974, Tenova I2S has specialized in providing customers the highest quality solutions in a broad range of mill types for production of stainless steel, carbon steel, specialty steels and
hot-rolled strip in the finishing mill of an ESP line. Referred to as “ultra-thin rolling control,” the system is essentially an adapted control concept that has been successfully applied many times in tandem cold mills. When rolling below a certain strip thickness, the control mode is switched from speed control
SMS group offers various cold roll mill technologies for copper, steel and aluminum like tandem cold mill, 18 HS mill, reversing mill, skin pass mill, single stand cold mill

dem Cold Rolling Mill of Arcelor Eisenhütten-stadt GmbH, ABB replaced the drive and automation equipment as well as the process control computer for production management and presetting. In addition to new technological controls for roll gap, bending systems, thickness, tension and flatness, the rolling mill received a new basic
The cold mill pilgering process uses ring dies and a tapered mandrel to reduce tube cross sections by up to 90 percent. Because the process relies on large number of small forming steps, the result is tube or pipe that has nearly homogenous material characteristics. It is suitable for every metal.
Tandem cold rolling process is a nonlinear complex system with external and internal uncertainties and significant disturbances. The improvement in the quality of the final output depends on the control strategy of centerline thickness and interstand tension. This focuses on interstand tension control problem in 5-stand tandem cold rolling mills.
Ensuring that the CRM plant was commissioned within a record period of 24 months, it has a capacity now to produce 10 MT per year cold rolled coils. On average 350 coils are manufactured per day. The consistent cold rolled quality has enabled JSW to produce steel at a very competitive p for the automotive and process industries.
Jul 19, 2017· However, most of the cold rolling mills are 6-high UCM rolling mills or 4-high CVC rolling mills. Given that the 4-high CVC mill has roll shifting function, it can use the K-WRS technology to realize similar function of the 6-high UCMW mill . However, the edge drop control capacity of the 6-high UCM rolling mill is obviously insufficient
Thanks to its broad range of cold rolling mills for strip widths from 60 to 2,100 mm, ANDRITZ Metals has been one of the preferred cold rolling technology suppliers for decades. The supply focuses on 2-high rolling mills, high-capacity 4-high reduction rolling mills, and inline skin pass mill stands.
