The leading performance of hot rolled sheet for the new generation of railway wagons in Pangang

Recently, Panzhihua Iron and Steel Co., Ltd. relied on independent innovation to successfully complete the research on the development of high-strength and atmospheric corrosion resistant hot-rolled steel sheets for 450 MPa class railway trucks, and officially transferred them into production and use. The research results use Pangang's original vanadium-nitrogen alloy process and a number of patented proprietary technologies to produce high-strength hot-rolled weathering sheets for a new generation of railway wagons, namely high-strength and atmospheric corrosion-resistant hot-rolled steel sheets for 450 MPa class railway wagons. . After testing, the comprehensive physical performance index of production is at the domestic leading level, which lays a solid foundation for the high-speed railway passenger transportation and heavy cargo transportation in China.
High-strength hot-rolled weathering panels for the new generation of railway wagons in Pangang are the result of integrated innovation. First, the vanadium-nitrogen alloy that can only be commercialized by American Vanadium Company and China Panzhihua Iron and Steel Co., Ltd. is used to improve its strength. Secondly, the technical route controlled by calcium treatment and hot rolling process is adopted, which breaks through the smelting and low-carbon of low-carbon and low-sulfur steel. The “bottleneck” of nitrogen steel smelting, nitrogen strengthening optimization and tissue control technology has formed a complete set of steel plates with high strength, high toughness, high plasticity, obvious yield point and excellent weldability and corrosion resistance. technology. Third, a utility model patent, an invention patent and a proprietary technology that is applying for invention patents formed during the research period have been promoted and applied in the production of other products of Panzhihua Iron and Steel Co., Ltd., and achieved remarkable economic benefits and society. benefit. At present, the 450 MPa Q450NQR1 hot-rolled weathering board produced by Panzhihua Iron & Steel Co., Ltd. has passed the certification of the Ministry of Railways, and the products have been well received by users.

Sheet Metal Stamping

A sheet metal stamping operation is one in which sheet metal is cut and formed into a desired shape or profile. Although a sheet metal stamping process may utilize numerous types of special machines, three basic items are essential: the sheet metal from which the part is to be made; the stamping press; and the stamping die.

With the exception of a specialized sheet metal stamping process commonly referred to as hot stamping, most sheet metal stamping operations involve cold forming. This essentially means that no heat is intentionally introduced into the die or the sheet material. However, keep in mind that although stamping is a cold-forming process, heat is generated. Cutting or forming sheet metal creates friction between the die and the metal-much like the friction and heat that occur when you rub your hands together.
