In a remarkable display of innovation and technical prowess, Benxi Steel Group has successfully rolled a 2190mm ultra-wide hot-rolled steel plate on its 2300 hot-rolling production line, setting a new national record in China. This achievement not only fills a technological gap in the domestic market but also highlights the growing capabilities of advanced steel mill equipment and rolling mill technology.

Pushing the Limits of Rolling Mill Technology

Traditional hot-rolling mills typically produce steel plates with widths between 1500mm and 2000mm. Pushing beyond the 2100mm mark requires extreme precision, robust steel mill MRO (Maintenance, Repair, and Operations), and innovative process adjustments.

Benxi Steel’s engineers optimized the rolling models, adjusted technical parameters, and selected specialized roller types to ensure superior shape, coil consistency, and performance uniformity. The successful production of the 2190mm plate demonstrates how modern rolling mills can operate at the outer limits of their design—with the right expertise and support.

Applications Across Key Industries

This ultra-wide hot-rolled plate can directly replace some medium-thick plates in applications such as:

• Large-diameter longitudinal welded pipes for major pipeline projects

• Shipbuilding

• Bridge construction

• New energy equipment

By reducing weld seams by more than 30%, these plates enhance structural integrity, improve production efficiency, and support lighter, stronger designs.

The Role of High-Performance Steel Mill Equipment and MRO

Achieving such milestones isn’t just about the rolling mill itself. It also depends on high-quality steel mill equipment, consistent steel mill MRO, and a proactive approach to technological upgrades. Benxi Steel’s success underscores the importance of:

• Precision machinery

• Regular maintenance

• Innovative roll design and replacement parts

• Real-time monitoring and process control

Strengthening the Chain: From Production to Application

This breakthrough enhances Benxi Steel’s product range and reinforces its competitive edge in the global market. It also activates a “chain reaction” toward low-carbon, high-value transformation across the steel industry.
