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.

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。
