Faced with fierce market competition in the silicon‑steel industry recently, Baosteel Silicon Steel Division has targeted production bottlenecks of high‑end 0.23 mm grain‑oriented silicon steel for technical research. By optimizing roll‑change procedures and innovating operation modes, it has achieved dual improvements in production capacity and efficiency.
The 0.23 mm grain‑oriented silicon steel features sophisticated craftsmanship and high production difficulty. Time‑consuming roll change and unstable rolling have long‑standing pain points. Based on on‑site production conditions, the RCM work area held special discussions to optimize operation workflows and establish standardized, high‑efficiency working specifications. To address operators’ concerns over speed increase, the team carried out training including simulation practice and experience sharing to overcome technical weaknesses. The rolling line saw over 20 % rise in rolling speed, unlocking full production potential with stable product quality.
In February this year, the daily output of 0.23 mm grain‑oriented silicon steel hit a new phased high. Roll‑change time kept decreasing, saving 2 minutes per roll change, which greatly boosted production benefits and market competitiveness.
A number of young backbones emerged during the technical campaign. New recruit Zhang Wenqiang dedicated himself to roll‑change operations and repeatedly set new job records. His fastest operation reached 60 % of the average duration, breaking post records five times in total. He drove the whole team to pursue higher efficiency and fostered a positive atmosphere for mutual improvement.
Going forward, the Silicon Steel Division will keep optimizing production processes and prioritizing technological innovation to advance the high‑quality development of high‑end grain‑oriented silicon steel.
