3800mm Wide And Thick Plate Production Line, Hot Test Success!

At 8:58 am on December 16, 2024, the 3800mm roughing mill of West China Special Steel Wide and Thick plate began rolling. After finishing rolling, straightening, cooling and other processes, the first qualified steel plate was born! The whole production process is stable, the steel plate size accuracy is high, the plate shape is straight, and the surface quality is good, which indicates that the thermal load test has been a complete success!

Since the start of the project on December 15, 2023, the company's leaders have attached great importance to the project, the project command department has been carefully organized and scientifically deployed, and the construction units and factory employees have overcome difficulties and worked together to promote the rapid progress of the project in terms of quality and quantity. The hot test plan is thorough and complete, the prenatal training of the operators is comprehensive and meticulous, and the wide and thick plate project is forced to meet the hot test conditions on schedule, and a hot test is successful.

The 3800mm wide and thick plate production line of Huaxi Special Steel adopts two-stand high-stiffness four-high rolling mill, and the basic automation and process automation system adopts the world-leading PRIMETALS technology to ensure the thickness and width accuracy of the products. The strong pre-straightener and the hot straightener create conditions for the production of wide and thick plates with good flatness; Online ultrasonic automatic flaw detection equipment to ensure that the internal quality of products is good. Designed annual output of 2 million tons, the variety covers high-rise building structural steel, welding structural steel, bridge structural steel, weather resistant structural steel, ship and ocean engineering structural steel, boiler and pressure vessel steel, pipeline steel plate, automobile girder steel plate, high strength wear-resistant steel plate for construction machinery, etc. The product specifications are: thickness 6mm ~ 200mm; Width 1600 ~ 3650mm; The length ranges from 6000mm to 18000mm.

The success of the hot test marks that Huaxi Special Steel has practiced the group's strategy of developing steel varieties, improved the product structure of Huaxi Special Steel, realized the complete industrial chain of iron, steel and materials, and enhanced the core competitiveness of the enterprise in the market, which is another milestone in the history of Huaxi Special Steel!
