Abstract: The inclusion, structure and texture of 0.5 mm cold rolled sheet of non-orientation silicon steel-0.003C 1.46Si,0.38Al have been tested and analyzed. The analyzed results showed that difference in anisotropy of iron loss of sample was 7.56%～11.01%.Reasonably increasing finishing rolling temperature of non-orientation silicon steel 50W470 is available to increase density of texture component and prolonging continuous annealing time of cold rolling sheet is available to enough grow of directional grain, thus the anisotropy of iron loss reduces.

摘要： 对成分(％)为0．003C、1．46Si、0．38Al的0．5 mm冷轧无取向硅钢板进行夹杂物、组织和织构的测定与分析。分析结果表明,试样铁损各向异性为7．56％-11．01％;合理提高无取向硅钢50W470热轧时的终轧温度,有利于提高织构组分密度;同时延长冷轧板的连续退火时间,以利于位向晶粒充分长大,从而减少铁损的各向异性。
