硅钢片是电力工业的关键材料,据不完全统计发电量每增加一百度电,必须相应增加一公斤硅钢片用以制造电机及变压器,故它是用量最大的一种软磁材料,按重量计,占磁性材料的90～95％,占电工材料的40～60％。在钢铁业中,硅钢片生产迅速发展,在先进工业国中其产量约占钢材总产量的1％左右(美国0.9％,苏联1.2％,西德0.8％,日、英、法1.1％)。从本世纪初开 Silicon steel sheet is the key material for the power industry. According to incomplete statistics, for every 100-kilowatt increase in power generation, a kilogram of silicon steel sheet must be added to make a motor and a transformer. Therefore, it is the largest amount of soft magnetic material, , Accounting for 90 to 95% of magnetic materials, accounting for 40 to 60% of electrical materials. In the iron and steel industry, the production of silicon steel sheet has been developing rapidly. Its output in the advanced industrial countries accounts for about 1% of the total steel output (0.9% in the United States, 1.2% in the Soviet Union, 0.8% in West Germany, and 1.1% in Japan, Britain and France). From the beginning of this century
