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、河南周口當(dāng)?shù)匚滗摵蛯氫摓榇怼５靡嬗谖覈撹F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、河南周口當(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(jí)，高端硅鋼產(chǎn)品的需求會(huì)越來越迫切。我國與日韓等鋼鐵強(qiáng)國在這一領(lǐng)域的競(jìng)爭(zhēng)將會(huì)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、河南周口當(dāng)?shù)馗叽鸥须姍C(jī)用無取向硅鋼、河南周口當(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。

電工鋼硅鋼片半有機(jī)無鉻薄涂層K H4 C-5 EC-5-P C-6涂層通常以磷酸鹽無機(jī)成分為主，添加少量有機(jī)成分，不含有鉻元素，杜絕了用戶退火、河南周口本地發(fā)藍(lán)和使用過程中發(fā)生六價(jià)鉻含量超標(biāo)的可能性，性、河南周口本地環(huán)保性 。性能基本接近A 涂層，絕緣性好，沖片性好，在中性氣氛或弱還原性爐子氣氛中，可承受的應(yīng)力退火溫度一般可達(dá)800℃，在退火時(shí)，層間電阻會(huì)有一定降低。半有機(jī)無鉻厚涂層M --- C-5 EC-5-P C-6涂層基本情況和 K 涂層類似，膜厚增加，絕緣性更好，耐蝕性更好，沖片性也更好，焊接性略差。

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.
