On July 21, the 2300 production line of Bensteel Group successfully rolled 2190mm ultra-wide hot-rolled plates, setting a new record for the width of domestic hot-rolled coils. This product can meet the needs of large-diameter straight seam welding key pipeline projects, filling the domestic technical gap, and marking a leap in Bensteel Group's high-end steel manufacturing capabilities.

The plate width of traditional hot rolling units is usually concentrated in 1500-2000mm, while the width of 2190mm is close to the design limit of the equipment. Since the beginning of this year, Bengang Group has closely followed market trends, deeply integrated customer needs, and made every effort to provide targeted R&D and application solutions. After rolling 2175mm and 2180mm hot-rolled plates in May and June this year, the plate hot rolling plant has dug deep into its innovation potential and carried out technical breakthroughs in the millimeter battle.

During the rolling process of 2190mm ultra-wide hot-rolled plates, the plant accurately calculated the model, adjusted the rolling process, and correctly selected the roll type, so that the plate shape, coil shape and performance uniformity of the products reached the top level in the industry, and now has the conditions for mass production.

It is understood that the ultra-wide hot-rolled plates with a width of 2180-2190mm can directly replace some medium and thick plates, reducing the welding joints of new energy equipment by more than 30%, and significantly improving the structural strength and production efficiency. Based on its excellent engineering performance, the 2190mm ultra-wide hot-rolled plates produced by Bengang Group will be applied on a large scale in key areas such as shipbuilding and bridge construction. This technological innovation reflects the strategic support role of Bengang Group in the field of high-end material research and development, and fully demonstrates the responsibility and commitment of central enterprises in breaking through the "stuck neck" technical difficulties and serving national strategies.

The successful rolling of 2190mm ultra-wide hot-rolled plates has further broadened the specification range of Bengang's products, enhanced the market competitiveness and brand influence of "Bengang Manufacturing", and activated the "chain reaction" of the industrial chain's transformation towards low-carbon and high-efficiency.
