電工鋼硅鋼片硅鋼是一種硅鐵合金。用硅鋼軋制的片材是電工領(lǐng)域中應(yīng)用廣的軟磁材料，因而硅鋼片又稱電工鋼片。硅鋼片廣泛用于電動(dòng)機(jī)、發(fā)電機(jī)、變壓器、扼流圈、電磁機(jī)構(gòu)、繼電器及測量儀表中電機(jī)工業(yè)大量使用厚度為0.35～0.50mm的硅鋼片,用于：中型旋轉(zhuǎn)機(jī)，壓縮電機(jī)，通用馬達(dá)，小型精密電機(jī)，電動(dòng)汽車，壓縮機(jī)，通用電機(jī)，電源變壓器，精密變壓器，節(jié)能電機(jī)，焊機(jī)變壓器，穩(wěn)壓器，磁性密封器，加速器用電磁鐵，汽車電機(jī)等；在電信高頻技術(shù)中常用0.05~0.20mm的薄帶鋼片,以便更有效地降低渦流損耗。熱軋硅鋼片厚度為0.35～0.50mm，密度為7.55～7.70g/cm3,多用于大、中、小型交、直流電動(dòng)機(jī)；冷軋無取向硅鋼片厚度為0.35～0.50mm，密度為7.65～7.75g/cm3，多用于大型交流發(fā)電機(jī)、電動(dòng)機(jī)，大、中、小型交、直流電動(dòng)機(jī)；冷軋取向硅鋼片厚度為0.23mm 0.27mm 0.3mm 0.35mm，密度為7.65g/cm3,多用于電力變壓器、油浸式變壓器，干式變壓器，電抗器、磁放大器等；冷軋取向薄帶厚度為0.05～0.20mm，多用于無線電高頻變壓器。

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.
