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B27G120表示公稱厚度為0.27mm普通取向電工鋼，鐵損的保證值P17/50不大于1.20W/kg；B30P105表示公稱厚度為0.30mm高磁感取向電工鋼，鐵損的保證值P17/50不大于1.05W/kg；B27R090表示公稱厚度為0.27mm磁疇細(xì)化高磁感取向電工鋼，鐵損的保證值P17/50不大于0.90W/kg；電工鋼主要分為晶粒取向電工鋼和晶粒無取向電工鋼兩大類。取向電工鋼易磁化晶粒方向沿軋制方向分布，軋制方向具有高磁感、黑龍江大慶同城低鐵損及低磁致伸縮等優(yōu)良特性，同時(shí)還可通過磁疇細(xì)化的技術(shù)處理，獲得更低鐵損的性能，廣泛應(yīng)用于變壓器行業(yè)領(lǐng)域。

電工鋼硅鋼片近20年來，我國硅鋼產(chǎn)業(yè)取得了長足的進(jìn)步，這其中以首鋼、黑龍江大慶當(dāng)?shù)匚滗摵蛯氫摓榇?。得益于我國鋼鐵行業(yè)全流程的技術(shù)進(jìn)步，這些企業(yè)在控制無取向硅鋼整體質(zhì)量穩(wěn)定性和取向硅鋼方面已經(jīng)具有較高技術(shù)實(shí)力。2014年我國硅鋼生產(chǎn)達(dá)到823萬噸，高端產(chǎn)品有20~30萬噸的進(jìn)口量，2015年，我國共生產(chǎn)電工鋼約836萬噸，進(jìn)口量進(jìn)一步下降到14萬噸。但是，與日本相比我國在高端電工鋼領(lǐng)域仍有不小的差距，這集中體現(xiàn)在高磁感無取向硅鋼、黑龍江大慶當(dāng)?shù)爻丸F損Hi-B取向硅鋼和高硅鋼等產(chǎn)品上。例如，新日鐵公司(現(xiàn)新日鐵住金)能夠?qū)崿F(xiàn)0.15~0.35mm系列厚度規(guī)格極低鐵損Hi-B取向電工鋼的穩(wěn)定供貨，引領(lǐng)取向硅鋼工藝發(fā)展。在特殊用途硅鋼方面，日本鋼管公司(現(xiàn)JFE)通過氣相沉積法(CVD)滲硅的方式實(shí)現(xiàn)了高硅鋼薄帶的供貨。隨著我國裝備制造業(yè)的產(chǎn)業(yè)升級，高端硅鋼產(chǎn)品的需求會越來越迫切。我國與日韓等鋼鐵強(qiáng)國在這一領(lǐng)域的競爭將會更加激烈，這就要求我國相關(guān)科研人員通過革命性創(chuàng)新進(jìn)行下一代硅鋼生產(chǎn)技術(shù)的研發(fā)，引領(lǐng)世界電工鋼技術(shù)的發(fā)展。低鐵損、黑龍江大慶當(dāng)?shù)馗叽鸥须姍C(jī)用無取向硅鋼、黑龍江大慶當(dāng)?shù)乇∫?guī)格超低鐵損高磁感取向硅鋼和中高頻節(jié)能電器用高硅鋼是電工鋼產(chǎn)業(yè)的發(fā)展方向。
