This mill, equipped with dual work rolls and advanced automation systems, is set to boost efficiency and precision. The start of production is slated for Spring 2026, marking a significant stride in the company's pursuit of steel strip excellence.ArticleWaelzholz Brasmetal, a leading producer of cold-rolled steel strip based in Germany, is embarking on a journey towards even greater excellence in steel strip production. To achieve this goal, the company has once again chosen Danieli, renowned for its cutting-edge technology in the steel industry.In an expansion project at their São Paulo, Brazil facility, Waelzholz Brasmetal is set to introduce a state-of-the-art four-high reversing mill. This mill is poised to revolutionize the production of high-performance steel strip, meeting the demands of a wide range of specialized steel grades.The capabilities of this cold rolling mill are truly remarkable. It will process a diverse mix of special steel grades, starting from an initial thickness of 6.0 mm and reducing it to a minimum finish thickness of just 0.25 mm. The mill can handle strip widths of up to 670 mm, demonstrating its versatility.One standout feature of the Danieli four-high reversing mill is the inclusion of dual work rolls, a design aimed at optimizing the rolling process. It comprises one set of work rolls with substantial diameters, efficiently handling heavy-gauge incoming thicknesses and standard products. Simultaneously, another set of work rolls with smaller diameters is reserved for special products, ensuring minimum exit thicknesses for high-strength materials.The mill is meticulously designed with independently driven work rolls, known as a twin-drive system. Additionally, it incorporates a unique set of high-torque drive spindles, enabling both sets of rolls to operate seamlessly.The electrics and automation for this project are in the capable hands of Danieli Automation. They will provide the HiPAC real-time automation system, optimized for Industry 4.0 readiness. This will be seamlessly integrated with the customer's proprietary process data management system, enabling intelligent data analysis.The production for this cutting-edge four-high reversing mill is scheduled to commence in Spring 2026. It marks a significant step forward in Waelzholz Brasmetal's commitment to pushing the boundaries of steel strip production.This decision follows the successful installation of a similar cold rolling mill at the Waelzholz plant in Taicang, China, in 2020, demonstrating the company's dedication to staying at the forefront of steel technology.ConclusionWaelzholz Brasmetal's investment in advanced technology with Danieli signifies its dedication to achieving new heights in cold-rolled steel strip production. The forthcoming four-high reversing mill promises unmatched versatility, precision, and efficiency, catering to a spectrum of specialized steel grades. This move aligns with the company's commitment to innovation and excellence in the steel industry.
