【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。
【Abstract】 In Cheng Steel,the CGW800 non- oriented electrical steel is successfully developed with process of hot metal pre- treating,vanadium extracting with converter,smelting with converter,RH refining,continuous casting and rolling. In the steel,the carbon content is not higher than 0. 006 0%,nitrogen less than0. 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 pr…
