Application Innovation (Ultra-Small Diameter Rolls Boost High-Strength Steel Production)

In December 2025, the ultra-small diameter work roll technology at Benxi Iron and Steel Plate Cold Rolling General Plant achieved stable application, supporting a breakthrough in GPa-grade high-strength steel rolling. By optimizing roll configuration and processes, the technology reduces rolling force and roll consumption, solves problems such as difficult shape control and fast roll wear in high-strength steel rolling, and enhances the competitiveness of automotive sheet products.
