硅钢片中由于硅元素的加入使铁素体的硬度显著提高,因而脆性大大增加。但硅含量小于3.3%的冷轧硅钢片在酸洗、轧制等加工过程中是没有困难的。此外,碳元素是影响硅钢片磁性的最有害元素之一,必须尽力脱去。为了得到合格的产品,一般认为在成品退火前碳含量应小于0.015%;如果要得到更高牌号的产品,则碳含量应在0.01%以下。冷轧厂生产流 Silicon steel sheet due to the addition of silicon to ferrite hardness significantly increased, so greatly increased brittleness. But the silicon content of less than 3.3% of the cold-rolled silicon steel pickling, rolling and other processing is not difficult. In addition, carbon is one of the most detrimental elements that affect the magnetic properties of silicon steel and must be removed as much as possible. In order to get a qualified product, it is generally believed that the carbon content should be less than 0.015% before the finished product is annealed; if it is to obtain a higher grade product, the carbon content should be below 0.01%.
