高速冲床用高硬度50BW600产品硬度和强度指标与普通产品相比,硬度指标要达到125Hv以上,抗拉强度要达到415MPa以上,同时要求具有优良的电磁性能,铁损值要求小于4.2W/kg。热轧工艺对产品的组织和性能具有重要影响,在合理的化学成份设计和冷轧工艺基础上,通过不同热轧工艺方案的试验,得到最佳的热轧工艺参数,保证产品的力学性能和电磁均达到最佳。 High-speed punch with high hardness 50BW600 product hardness and strength indicators compared with ordinary products, the hardness index to reach more than 125Hv, tensile strength to reach more than 415MPa, while requiring excellent electromagnetic properties, iron loss requirements of less than 4.2W / kg. The hot rolling process has an important influence on the microstructure and properties of the product. Based on reasonable chemical composition design and cold rolling process, the optimal hot rolling process parameters are obtained through experiments of different hot rolling process schemes to ensure the mechanical properties and Electromagnetic to achieve the best.
