采用氮化硅铁和高纯氮气作为含3%Si的取向硅钢抑制剂的氮源,在1340℃的热轧温度下,借助OM和TEM观察和分析,研究两种不同的正火工艺对钢板中抑制剂析出的种类、大小、数量、均匀程度的影响。结果表明:在热轧态后对钢板进行正火处理有利于抑制剂的析出,从而可以利用氮气取代氮化硅铁作为氮源来生产取向硅钢。 Using nitrogen ferrosilicon and high-purity nitrogen as the nitrogen source of 3% Si-oriented silicon steel inhibitor, with the aid of OM and TEM observation and analysis at 1340 ℃ hot rolling temperature, the effects of two different normalizing processes on the steel sheet Inhibitor precipitation in the type, size, quantity, uniformity of the impact. The results show that the normalizing of the steel plate after hot rolling is favorable for the precipitation of inhibitor, so that the silicon steel can be produced by using nitrogen instead of ferrosilicon nitride as nitrogen source.
