In order to promote the application of hot-rolled H-beam products in the automotive industry, at the end of November last year, Maanshan invited six automakers, two sellers and the China Automobile Association Special Vehicle Association, including the China CIMC Vehicle Group, to provide automotive girders for Maanshan Iron and Steel Co., Ltd. The hot-rolled H-beam product development project was exchanged and reached a consensus to form a preliminary intention for the cooperation between the supply and demand side in the development of hot-rolled H-beam steel girder trial steel, and proposed the hot-rolled H-beam type and specification "recommendation table" for automobile girder. . At the end of March this year, Magang's development of automobile girders, special-purpose vehicle production plants and special-purpose vehicle associations officially selected the varieties and specifications of the developed automobile girder trial steels, and proposed to develop finished product supply manufacturers for trial use as soon as possible.
The large H-beam production line of the No. 3 Steel Rolling Plant of Maanshan Iron and Steel Co., Ltd. undertook the development and production of this product. In order to ensure the high strength performance and surface quality of the MGL finished product after rolling, the production technicians of the No. 3 Steel Rolling Mill of Maanshan Iron and Steel Co., Ltd. conducted repeated demonstrations and operation drills on the entire production process, and ensured hot rolling under careful development plan. The H-beam steel girder trial steel was developed successfully.
It is reported that the hot-rolled H-beam automotive beam test steel developed by Maanshan Iron & Steel Co., Ltd. will carry out technical feasibility demonstration through relevant domestic institutions, and provide technology for further promotion and application of hot-rolled H-beams for automobile girder and the development of "Hot-rolled H-beam steel girder industry standards".
