The afternoon of January 9th 1 09, hot dip galvanized by Xichang steel vanadium providing a substrate of ultra high strength steel with 1180 MPa in Anshan automobile, Thyssen Krupp Automobile Co. Ltd. (Chongqing) steel was successfully launched. After testing, the product has reached the quality level of the same products at home and abroad. This indicates that Pangang has made new breakthroughs in R & D and production of high strength steel for automobile, and has become one of the few enterprises that can produce ultra high strength steel in China.
Super high strength 1180 MPa car steel is mainly used for high grade automobile outer board, structural plate, and automobile anti-collision parts. Compared with ordinary high-strength steel, it has better ductility, welding performance and stamping performance. It is currently the first choice of "Star" material that meets the requirements of lightweight development and environmental protection in the automotive industry. The production process of this steel has high requirements, high equipment precision and high operation level. At present, only a few iron and steel enterprises in the world have dared to ask for it.
In recent years, in the face of fierce competition in steel market cars, Panzhihua in accordance with the strategic concept of "doing fine steel, automotive steel production base has a first-class technical level of equipment technology in Xichang vanadium steel construction investment, have developed a high strength steel with 590 MPa, 980 MPa grade car. In 2017, Panzhihua Iron and steel (Pangang) carried out the development of 1180 MPa super high strength automobile board.
Xichang steel vanadium from the steelmaking process of problem oriented, establish the quality checking mechanism, the effect of refining of ultra high strength 1180 MPa for automobile steel each link, the key control point for investigation and optimization, curing, formation of operating standards, make clear the temperature condition on the quality of molten iron, semi steel quality, technology path. In the rolling process, we fully excavate the equipment advantages of hot rolling and acid rolling line, summarize the experience of producing 590 MPa and 980 MPa grade high strength steel, and tackle every key technology that restricts the production of 1180 MPa automotive steel. At the beginning of December 2017, the difficult smelting steel smelting finally one-time success.
In December 12, 2017, the super high strength 1180 MPa chill products produced by Xichang steel and vanadium were sent to Chongqing, which laid a solid foundation for Angang Thyssen Krupp (Chongqing) Automotive Steel Co., Ltd. to produce hot dip galvanized, ultra-high strength, 1180 MPa automotive steel.
