目前,世界硅钢片的年总产量,已超过500万吨。国外除苏联、西德仍保留热轧硅钢片外,其它国家已很少生产热轧硅钢片了。在我国,虽然还在大量生产和使用热轧硅钢片,但是冷轧电机钢片的生产也有很大发展。目前可以大量提供质量好的DW系列冷轧无取向钢带(片),它相当于新日铁的HILITCORE(包括H9至H23)和HOMECORE(包括H30至H60)等品种。下面就国产冷轧电机钢片的种类、特点、牌号和性能、主要用途以及优点作一简单介绍,仅供选用材料时参考。
At present, the annual output of silicon steel in the world has exceeded 5 million tons. Foreign countries except the Soviet Union, West Germany still keep hot-rolled silicon steel sheet, other countries have rarely produced hot-rolled silicon steel sheet. In our country, although the hot-rolled silicon steel sheets are still being mass-produced and used, the production of cold-rolled steel sheets has also been greatly developed. At present, DW series cold-rolled non-oriented steel strips (sheets) of good quality can be provided in large quantity, which is equivalent to the varieties of HILITCORE (including H9 to H23) and HOMECORE (including H30 to H60) of Nippon Steel. Below the domestic cold-rolled electrical steel sheet types, characteristics, grades and performance, the main purpose and advantages for a brief introduction, only for reference material selection.
