本发明是关于硅钢片的制造法。如果采用本发明方法,就可以得到铁损(在10000高斯,50赫兹的值)为2.3瓦特/公斤以下的电磁用冷轧硅钢片。本发明是熔炼含碳量约为0.03~0.06%的未镇静钢水,为了使钢水的含碳量下降到约0.02%以下,将其进行真空脱碳处理,为了脱氧首先加入铝,接着添加硅,然后将钢水铸成
The present invention relates to a method of manufacturing a silicon steel sheet. According to the method of the present invention, a cold-rolled silicon steel sheet for electromagnetic use having an iron loss (at 10,000 gauss and a value of 50 Hz) of 2.3 W / kg or less can be obtained. In the present invention, unaltered molten steel having a carbon content of about 0.03 to 0.06% is melted. In order to reduce the carbon content of the molten steel to about 0.02% or less, the molten steel is subjected to vacuum decarburization to first add aluminum for deoxidation followed by addition of silicon, Then cast the molten steel
