German cold-rolled steel strip producer Waelzholz has ordered a new four-high reversing mill to increase the production of high-performance steel strip as part of its expansion project at Waelzholz Brasmetal in São Paulo, Brazil. The new cold-rolling mill will roll a wide mix of special steel grades from an entry thickness of 6.0mm down to a minimum finish thickness of 0.25mm, at a maximum strip width of 670mm.
A notable special feature of the Danieli four-high reversing mill stand is the dual work rolls, which will achieve efficient rolling performance. One set of work rolls with large diameters will cope with heavy-gauge incoming thicknesses and standard products, while another set of work rolls with small diameters will be reserved for special products, to achieve minimum exit thicknesses on high-strength materials.
The mill will be equipped with twin-drive work rolls and high-torque drive spindles. Electrical systems and automation supplied by Danieli Automation will include the HiPAC real-time automation system. A new, intelligent data analysis system, ready for Industry 4.0, will be connected to the existing process data management system.
Production at the new four-high reversing mill is planned to start in spring 2026.
