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.

電工鋼硅鋼片根據(jù)生產(chǎn)方式可分為熱軋電工鋼和冷軋電工鋼。熱軋硅鋼片因其性能落后近年已經(jīng)逐步淘汰。根據(jù)晶體取向聚集程度將硅鋼分為無取向和取向是為廣泛接受的方法。冷軋無取向硅鋼是指0.5％~4.0％(Si＋Al)的合金，冷軋至0.65mm、湖北十堰同城0.5mm和0.35mm后經(jīng)退火涂層后制成。相比取向硅鋼，其晶?？棙?gòu)類型較為漫散，各個方向上具有較為均勻的磁性能，而且磁各向異性較低，主要用作各類型電機(jī)和發(fā)電機(jī)的鐵芯疊片。冷軋產(chǎn)品厚度精度，尺寸公差等級，表面光滑度都達(dá)到較高水平，從而提高了產(chǎn)品疊片系數(shù)和材料的磁性能。冷軋無取向硅鋼生產(chǎn)工藝流程圖如圖1所示。
