摘要/Abstract

摘要： 采用30 kg真空感应炉-50 mm铸坯-热轧2.0~2.3 mm板-冷轧0.5 mm薄板流程的模拟CSP工艺生产0.005%C、0.42%Si和0.002%C、0.98%Si的无取向电工钢。结果表明，两种电工钢的热轧板经900 ℃ 5 min常化处理后，铁损P.s0分别由原有的7.01 W/kg和7.34 W/kg降至6.49 W/kg和5.96 W/kg,冷轧板经820～910 ℃ 退火后随退火温度的提高铁损降低至5.15 W/kg。

Abstract: Two non-oriented electrical steels 0.005C-0.42Si and 0.002C-0.98Si were produced by the simulated CSP (compact strip production process):30 kg vacuum induction furnace-50 mm cast slab-2.0~2.3 mm hot rolled plate - 0.5 mm cold rolled sheet process. Results showed that after normalizing at 900 ℃ for 5min,the iron lose P.sso of two e- lectrical steels reduced respectively from original7.01 W/kg and7.34 W/kg to6.49 W/kg and 5.96 W/kg,and after 820～910 ℃ annealing,with increasing annealing temperature the iron lose of cold rolled sheet decreased to 5.15 W/kg.
