硅钢片是电力和电讯制造工业不可缺少的重要磁性材料。目前,世界上能生产硅钢片的国家有二十多个。几个主要工业国家硅钢片的产量约占钢材总产量1％左右。年产10万吨以上硅钢片的国家有中国、苏联、美国、西德、英国、法国、日本、意大利、比利时和西班牙。随着科学技术的发展,对硅钢片的要求也越加严苛。冷轧硅钢片以其表面质量和冲制加工性能好、磁感高、铁损低,节约电能效果好等特点,在工业发达国家得到了很快
Silicon steel sheet is an indispensable important magnetic material in power and telecom manufacturing industry. At present, there are more than 20 countries in the world producing silicon steel sheets. The output of silicon steel in several major industrial countries accounts for about 1% of the total steel output. Countries with an annual output of 100,000 tons of silicon steel are China, the Soviet Union, the United States, West Germany, Britain, France, Japan, Italy, Belgium and Spain. With the development of science and technology, the demand for silicon steel is also more stringent. Cold-rolled silicon steel sheet with its surface quality and punching processing performance, high magnetic induction, low iron loss, energy saving effect is good, etc., in industrialized countries have been very fast
