电工钢硅钢片硅钢是一种硅铁合金。用硅钢轧制的片材是电工领域中应用广的软磁材料，因而硅钢片又称电工钢片。硅钢片广泛用于电动机、发电机、变压器、扼流圈、电磁机构、继电器及测量仪表中电机工业大量使用厚度为0.35～0.50mm的硅钢片,用于：中型旋转机，压缩电机，通用马达，小型精密电机，电动汽车，压缩机，通用电机，电源变压器，精密变压器，节能电机，焊机变压器，稳压器，磁性密封器，加速器用电磁铁，汽车电机等；在电信高频技术中常用0.05~0.20mm的薄带钢片,以便更有效地降低涡流损耗。热轧硅钢片厚度为0.35～0.50mm，密度为7.55～7.70g/cm3,多用于大、中、小型交、直流电动机；冷轧无取向硅钢片厚度为0.35～0.50mm，密度为7.65～7.75g/cm3，多用于大型交流发电机、电动机，大、中、小型交、直流电动机；冷轧取向硅钢片厚度为0.23mm 0.27mm 0.3mm 0.35mm，密度为7.65g/cm3,多用于电力变压器、油浸式变压器，干式变压器，电抗器、磁放大器等；冷轧取向薄带厚度为0.05～0.20mm，多用于无线电高频变压器。

电工钢硅钢片硅钢以铁芯损耗(简称铁损)和磁感应强度(简称磁感)作为产品磁性保证值。硅钢铁损低可节省大量电能，延长电机和变压器工作运转时间和简化冷却系统。由于硅钢铁损造成的电量损失占全年发电量的2.5％～4.5％，其中变压器铁损约占50％，1～100kW小型电机约占30％，日光灯镇流器约占15％。硅钢磁感高，铁芯的激磁电流降低，也节省电能。硅钢磁感高可使设计的 磁感(Bm)高、本地铁芯体积小、本地重量轻，节省硅钢、本地导线、本地绝缘材料和结构材料等，既使电机和变压器损耗和制造成本降低，又便于组装和运输。由带齿圆形冲片叠成铁芯的电机在运转状态下工作。要求硅钢板为磁各向同性，用无取向硅钢制造。由条片叠成铁芯或由条带卷绕成铁芯的变压器在静止状态下工作，用磁各向异性大的冷轧取向硅钢制造。此外，要求硅钢具有好的冲剪性，表面光滑平整和厚度均匀，好的绝缘膜和磁时效小。

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.
