1974年,我国从日本引进冷轧硅钢生产专利技术,在武钢建立了我国第一家冷轧硅钢片厂。1978年正式投产,从而结束了我国不能生产冷轧硅钢片的历史。武钢自1978年10月开始生产硅钢至今已经27个年头了,截至2004年底共生产硅钢440.2万吨,其中取向硅钢130.8万吨,无取向硅钢309.4万吨,所生产的一般取向硅钢最高牌号不仅达到了30Q130水平,而且达到了30Q120和27Q120水平,HiB钢最高牌号达到了30QG105的水平,无取向硅钢最高牌号达到35W230水平。品种规格由引进时的4个品种32个牌号规格,跃升到20个品种、122个牌号规格,满足了国内电器产品对不同类型铁芯的需求。
In 1974, our country imported the patent technology of cold-rolled silicon steel from Japan and established our first cold-rolled silicon steel sheet factory in WISCO. 1978 officially put into operation, thus ending our history can not produce cold-rolled silicon steel. Since its introduction in October 1978, WISCO has been producing silicon steel for 27 years now. By the end of 2004, a total of 4,402,000 tons of silicon steel were produced, including 1,380,000 tons of oriented silicon steel and 3.094 million tons of non-oriented silicon steel. The highest grades of general-oriented silicon steel produced not only reached 30Q130 level, and reached the level of 30Q120 and 27Q120, HiB steel highest grade reached 30QG105 level, the highest grade of non-oriented silicon steel reached 35W230 level. Variety specifications from the introduction of 4 varieties of 32 brands specifications, jumped to 20 varieties, 122 brands specifications to meet the domestic electrical products for different types of core needs.
