Hegang Shigang rolled out the largest special steel bar in China
News from our newspaper On June 13, Hegang Shigang rolled out the largest domestic special steel bar with a diameter of 400 mm. The successful rolling of this product has refreshed the current domestic bar rolling specification record and further enhanced the market competitiveness of HBIS in the field of special steel bars.
After inspection, the product’s surface quality, chemical composition, low magnification structure, external dimensions, and other performance indicators meet the standard requirements. The product has now been shipped to customers and will be used in the field of gas machinery manufacturing.
Hegang Shigang closely follows the technological development of the steel industry, aims at high-end manufacturing and the industry’s most cutting-edge materials, strengthens technological research, has the courage to challenge cutting-edge technical problems, and cultivates high-end products in the industry.
The customers of the 400 mm diameter super-sized bar rolled this time are the leading domestic gas machinery manufacturing enterprises. In the early stage, Hegang Shigang gave full play to the role of EVI (pre-supplier intervention), and deeply understood the customer’s requirements for the performance of raw materials.
Gangshigang’s vertical continuous caster and the largest domestic large-bar line blanking machine have the advantages of equipment, providing them with better materials and more personalized services, and helping customers develop new products.
Hegang Shigang concentrated its advantageous resources and carefully planned the processes of molten steel smelting, continuous casting, heating, and rolling. In order to ensure the successful rolling of this batch of products for the first time, the rolling mill conducted a full feasibility analysis on the 1350 billet rolling mill to roll 400mm bars in the early stage of production, and quickly completed the rolling pass, roll matching, and rolling procedures. and other process design.
At the same time, the R&D, technical, and equipment personnel worked out the production plan in coordination and conducted thorough training for the employees in the production link one by one, extensively solicited operational opinions, and optimized and refined the production plan. During the production process, they overcame technical bottlenecks such as material torsion and bending during the rolling of super-large bars, helping the product to be successfully rolled off the production line.
