电工钢硅钢片 电工钢板通常是以铁芯损耗和磁感应强度作为产品磁性保证值[1] [2] 。对电工钢板性能的要求如下：铁芯损耗（PT）低铁芯损耗是指铁芯在≥50Hz交变磁场下磁化时所消耗的无效电能，简称铁损，也称交变损耗，其单位为W/kg。这种由于磁通变化受到各种阻碍而消耗的无效电能，通过铁芯发热既损失掉电能，又引起电机和变压器的温升。电工钢的铁损（PT）包括磁滞损耗、山东东营本地涡流损耗（Pe）和反常损耗（Pa）三部分。电工钢板铁损低，既可节省大量电能，又可延长电机和变压器工作运转时间，并简化冷却装置。由于电工钢板的铁损所造成的电量损失占各国全年发电量的2.5％~4.5％，因此各国生产电工钢板总是千方百计设法降低铁损，并以铁损作为考核产品磁性的重要指标，按产品的铁损值作为划分产品牌号的依据。冷轧取向电工钢：冷轧取向电工钢是电工钢中的高端产品，与冷轧无取向电工钢相比，磁性具有强烈的方向性；在易磁化的轧制方向上具有优越的高磁导率与低损耗特性。取向钢带在轧制方向的铁损仅为横向的1/3，磁导率之比为6：1。用途：冷轧取向硅钢带主要的用途是用于变压器制造。

As an important indicator of quality, each country divides the grade by the iron loss value. The lower the iron loss, the higher the grade and the higher the quality.B. High magnetic induction strength. Under the same magnetic field, the silicon steel sheet with high magnetic sensitivity can be obtained. The volume and weight of the iron core of the motor or transformer made by it are relatively small, which can save silicon steel sheet, copper wire and insulating materials, etc.C. High stacking coefficient. The surface of the silicon steel sheet is smooth, flat and uniform in thickness, which improves the stacking coefficient of the iron core.D. Good punching property. This is more important for manufacturing small and micro motor iron cores.E. The surface has good adhesion and weldability to the insulating film.
