摘要
承钢采用铁水预处理(脱硫)→转炉提钒→转炉冶炼→RH精炼→连铸→轧制工艺,成功研发了无取向电工钢CGW800。试制的CGW800钢碳含量≤0.006 0%、氮含量<0.004 0%,热轧后的金相组织为铁素体和少量渗碳体,晶粒度5.5级,获得了较粗大、均匀的晶粒,钢板的成分和力学性能达到了标准要求。
In Cheng Steel, the CGW800 nonoriented electrical steel is successfully developed with process of hot metal pre - treating, vanadium extracting with converter, smelting with converter, RH refining, con- tinuous casting and rolling. In the steel, the carbon content is not higher than 0. 006 0% , nitrogen less than 0. 004 0% , the metallographic structure after hot rolling is ferrite and a little amount of cementite, grain size is 5.5 degree, relative large and even grain got. The composition and mechanical properties of the steel plate all meet standard.
