Nationwide Tandem Rolling Mill Advances Reported

The articles summarize a wave of developments in the continuous rolling mill sector since May 2026, led by patent breakthroughs from Shougang Zhixin and China First Heavy Industries and progress in projects run by Taiyuan Steel and MCC Jingcheng. Key innovations include Shougang Zhixin’s patent to reduce residual oil and iron on cold-rolled strips, and a May 2026 patent for a forging tooling system for continuous rolling mill support rolls that cuts costs and improves reliability; Shenke Co. is advancing rolling-motor components, including sliding bearings compatible with multiple mills. On the performance side, Wuhan Ganye unveiled an eighteen-roll, six-stand cold rolling process that enhances magnetic properties of grain-oriented silicon steel, while MCC Jingcheng’s domestically developed high-speed pickling and rolling unit reached 1800 m/min in trials, signaling China’s entry into the 1800 m/min high-speed era. The overarching focus remains domestic substitution of high-end equipment, plus improved production efficiency through new materials and processes. Collectively, these advances aim to push the industry toward greater self-reliance and higher output, with multiple achievements already implemented or nearing critical milestones.
