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_(1.5/50)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。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 P1.5/50 of two electrical steels reduced respectively from original 7. 01 W/kg and 7.34 W/kg to 6. 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.
