在资本主义国家中,日本生产硅钢片比较晚,到1924年才正式生产出热轧硅钢片,比英美等国大约晚20多年,产品质量也不高。直到1951年和1958年先后引进国外技术后,始生产出质量优良的硅钢片,但其硅钢片生产发展的速度却是资本主义国家中最快的。日本钢铁工业企业中能生产硅钢片的厂家为数不多。战前集中在八幡制铁(新日铁前身)、川崎制铁、中山制钢和富士制铁四家,主要生产热轧硅钢片;在产量上八幡制铁占50％以上,川崎制铁占40％,其余约占6％左右。战后钢铁企业经过分合改组有所变化,
In the capitalist countries, Japan produced silicon steel late, until 1924 was formally produced hot-rolled silicon steel sheet, about Britain and the United States and other countries about 20 years later, the product quality is not high. It was not until 1951 and 1958 that foreign technologies were successively introduced to produce high-quality silicon steel sheets. However, the production of silicon steel sheets was the fastest growing among the capitalist countries. One of the few steel-making companies in Japan’s steel industry is silicon steel. Prior to the war, the company focused on Yawata Iron (Nippon Steel predecessor), Kawasaki Steel, Zhongshan Steel and Fuji Steel, which mainly produced hot-rolled silicon steel sheets; Yawata Iron & Steel accounted for over 50% of the output, Kawasaki Steel Manufacturing 40%, the rest accounts for about 6%. After the post-war iron and steel enterprises changed by sub-group,
