Reversing Cold Rolling Mills for Flexible Steel Production

Innovative Features of the Steel Reversing Cold Rolling Mill

The steel reversing cold rolling mill is a versatile solution designed to meet the challenges of small to medium-sized production capacities and special steel grades. In the steel industry, achieving high-quality production with flexibility and efficiency is crucial. The reversing cold mill addresses these challenges by offering a compact design and advanced features that ensure stable operation and uncompromising strip quality.

In reversing cold mills, the tension reels are strategically placed at both ends of a single or two-mill-stand arrangement. This configuration allows for quick changes in rolling parameters for each coil, making it ideal for smaller-lot production of various product types, including high-grade silicon steel. The compact size and simple design facilitate easy access to equipment and machinery for maintenance purposes, while operation can be stopped and restarted flexibly. The advanced features of reversing cold mills from Primetals Technologies, based on the UC-MILL principle, ensure stable operation and uncompromising strip quality to meet strict tolerance requirements. Additionally, the HYPER UC-MILL technology can be applied to reversing cold mills for thinner high-strength material.

Single-Stand Reversing Cold Mill

A single-stand cold rolling mill is capable of producing 100,000 to 400,000 tons annually, depending on the product mix. Rolling schedules can be carried out with an even or odd number of passes to maximize mill availability and performance. The UC-MILL, equipped with work roll bending, intermediate roll bending, intermediate roll shifting, and all-straight-roll application, ensures enhanced flatness control. Strip flatness measuring equipment mounted at one or both ends of the mill, combined with multi-zone work roll cooling, meets the highest demands for flatness.

Two-Stand Reversing Cold Mill

Two-stand reversing cold mills developed by Primetals Technologies combine the flexibility of single-stand reversing mills with the capacity of conventional coil-to-coil tandem mills at substantially reduced investment costs. 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 of 300,000 tons annually of thin-gauge products or approximately 600,000 tons of thicker-gauge products.
