目前随着电工钢用户冲压设备的升级,冲压速度逐步提高,对电工钢产品的硬度和强度指标提出了更高的要求。与普通硬度级别的无取向硅钢相比,高硬度50BW600的Hv硬度提高15~20,达到125以上,同时对电磁性能指标也有较高要求。本钢通过化学成份和热轧及冷轧连退生产工艺的设计,经过小批量生产试验,满足用户要求。通过对工艺的严格控制,在大批量生产过程中,保证了产品的力学性能和电磁性的检验合格率。
With the current electrical steel users stamping equipment upgrades, stamping speed gradually increased, the electrical steel products hardness and strength indicators put forward higher requirements. Compared with ordinary hardness grade non-oriented silicon steel, Hv hardness of high hardness 50BW600 is increased by 15-20, reaching more than 125, meanwhile electromagnetic performance index is also higher. Bengang chemical composition and the hot-rolled and cold rolling back production process design, after small batch production test to meet user requirements. Through the strict control of the process, in the mass production process, to ensure the mechanical properties of products and electromagnetic test pass rate.
