目前工业发达国家正逐步以冷轧硅钢片取代热轧硅钢片。但在我国的硅钢片生产中,热轧硅钢片仍占很大比重,特别是电机硅钢片,冷轧的仅占7％左右。由于兴建冷轧硅钢片厂需要大量投资,而且供给合格的热轧卷板坯料也不易解决,因此,在一定时期 At present, industrialized countries are gradually replacing cold-rolled silicon steel sheets with cold-rolled silicon steel sheets. However, in our country’s silicon steel sheet production, hot-rolled silicon steel sheet still accounts for a large proportion, especially the motor silicon sheet, cold-rolled only about 7%. As the construction of cold-rolled silicon steel sheet plant requires a lot of investment, but also supply qualified hot-rolled coil blank is not easy to solve, therefore, in a certain period
