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.

電工鋼硅鋼片絕緣涂層特性7.2.1 絕緣涂層狀態(tài)產(chǎn)品通常以兩面涂敷絕緣涂層狀態(tài)交貨，涂層種類見表 2。絕緣涂層應可耐受絕緣漆、貴州遵義當?shù)刈儔浩饔?、貴州遵義附近機械油等介質(zhì)的侵蝕。本文件規(guī)定的絕緣涂層與國內(nèi)外相關技術規(guī)范規(guī)定絕緣涂層的近似對照可參見附錄 A(資料性附錄)，無取向電工鋼絕緣涂層的特性見附錄 B(資料性附錄)。絕緣涂層的厚度、貴州遵義附近自粘接涂層的剝離強度等技術要求如有特殊要求應在訂貨時協(xié)商，并在合同中注明。7.2.2 絕緣涂層附著性根據(jù)附錄 C（無取向電工鋼絕緣涂層附著性檢測和評級方法），產(chǎn)品的絕緣涂層的附著性級別按照附著性由高至低分為 A、貴州遵義附近B、貴州遵義附近C、貴州遵義附近D 四個級別。供貨時，產(chǎn)品涂層的附著性級別 應達到C 級。在剪切過程和供方規(guī)定的熱處理條件下進行熱處理時，涂層不得有大面積脫落，但是在剪切邊緣位置，涂層的輕微碎裂則允許存在。7.2.3 涂層絕緣電阻涂層絕緣電阻分為表面絕緣電阻和層間電阻，表面絕緣電阻單位為Ω·cm2/面，層間電阻單位為Ω·cm2/片，理論上，層間電阻是表面絕緣電阻的 2 倍。根據(jù)需方要求，經(jīng)供需雙方協(xié)商，可進行涂層絕緣電阻的檢測，并在合同中注明涂層表面絕緣電阻或?qū)娱g電阻的小值
