电工钢是中国国民经济建设中十分重要的原材料产品。由于国内产量有限,加上中国生产技术、产品研发起步较晚,电工钢的整体水平与国外比还有一定的差距,造成几十年来中国的冷轧电工钢,特别是高磁感、低铁损、薄规格的高级别的冷轧电工钢要用大量的外汇从国外进口。近年来这一格?
Electrical steel is a very important raw material product in China’s national economic construction. Due to the limited domestic output, coupled with the Chinese production technology, product development started late, the overall level of electrical steel and there is still a certain gap between foreign ratio, resulting in China’s decades of cold-rolled electrical steel, especially high magnetic induction, low iron Loss, thin-gauge, high-grade, cold-rolled electrical steel is imported from abroad with large amounts of foreign exchange. In recent years this grid?
