本专利是制造晶粒取向硅钢的一种改进工艺。电磁硅钢如同市场上大多数商品一样,是按质论价的。即使同一炉号的钢卷也是逐卷分级,按级销售的。某一铁心损失的钢卷,同另一个具有较差铁心损失的钢卷相比,在所有其他因素都相同的条件下,通常是定为较差的等级,并由此确定较低的销售价格。 This patent is an improved process for manufacturing grain-oriented silicon steel. Electromagnetic silicon steel, like most products on the market, is based on the quality of the price. Even if the same number of coil is also graded by volume, according to the level of sales. A coil lost in one core is usually rated poorer when all other factors are the same compared to another coil with a lower core loss and the lower sales price .
