Capacity Hits New High! Stable Mass Production of "Triple-size" Non-oriented Silicon Steel Achieved

2026 08/14

Recently, WISCO Limited under Baosteel achieved a major production breakthrough on the No.4 Steel No.2 Hot Rolling Line. The hot charging rate of triple-size non-oriented silicon steel has steadily exceeded 90% for three consecutive months, marking the official transition from trial production to stable mass supply.

As a high-end oversized non-oriented silicon steel product, triple-size silicon steel features larger length and width with higher requirements for rolling temperature and shape precision. It effectively improves downstream cutting efficiency and core performance, meeting the manufacturing demands of high-end motors and new energy equipment.

To solve production bottlenecks including quality fluctuation and low hot charging rate, a cross-department technical team optimized key rolling processes and greatly improved production stability.

Supported by digital intelligent manufacturing systems, the whole-process production management has been enhanced. Integrated steelmaking and rolling models realize real-time data tracking and rapid abnormal disposal, overcoming difficulties in heat loss control, quality uniformity and logistics scheduling.

In the next stage, WISCO Limited will further implement lean production, upgrade high-end silicon steel rolling technologies, and empower the high-quality development of new energy and high-end equipment industrial chains with superior electrical steel products.
