CSP流程生产全工艺无取向电工钢

为了简化传统无取向电工钢的生产工艺,降低消耗,提高无取向电工钢的磁学性能,通过氧气顶吹转炉(BOF)-RH真空处理-LF精炼炉-薄板坯连铸连轧(CSP)-酸洗连轧-连续退火流程,成功开发了全工艺冷轧无取向电工钢50W800并实现了批量化生产。研制的50W800铁损P_1.5/50<4.6W·kg^-1,磁感应强度B₅₀>1.71T,板形和表面质量良好,涂层具有优良的耐蚀性能和绝缘性能,能够满足电机行业的使用要求。

Development of full-processed non-oriented electrical steel in a CSP line

In order to meet energy conservation, consumption reduction and high quality, the full-processed non-oriented electrical steel 50W800 was successfully developed and produced in batch by a production flow of BOF steel-making, RH degassing, ladle furnace (LF) refining, compact strip production (CSP) line, cold rolling and continuous annealing. By testing, the magnetic properties of 50W800 are excellent:the iron-loss (P_1.5/50 is less than 4.6 W·kg^-1, the magnetic induction (B₅₀) is more than 1.71 T, the flatness and surface quality of products are fine, and the coating has the satisfied properties of insulation and corrosion resistance. The products are suitable for the motor manufacture industry.
