科冶金工程目錄1簡史2性能特點(diǎn)3分類4性能要求5生產(chǎn)工藝?酸洗?冷沖壓?退火?絕緣涂層簡史播報(bào)編輯1900年哈德菲爾德（R.A.Hadfield）報(bào)道，硅含量2.5%～5.5%的鐵硅合金具有比鐵更高的磁性。1903年開始生產(chǎn)熱軋片。1934年戈斯（GossN P）發(fā)展（110）[001]冷軋取向，沿鋼板軋制方向磁性明顯提高，適用于制作變壓器，1935年美國阿姆科（Armco）鋼公司開始生產(chǎn)，隨后又生產(chǎn)冷軋無取向。1949年阿姆科制成0.05mm和0.1mm厚的冷軋取向薄帶，用于軍事工業(yè)。60年代初美國開始大量生產(chǎn)硅含量<0.5%的低碳電工鋼。60年代末，某些國家陸續(xù)停止生產(chǎn)熱軋。1968年，日本新日鐵鋼公司開發(fā)并生產(chǎn)了高磁感取向（Hi-B鋼）。70年代中期，日本又陸續(xù)開發(fā)了幾個(gè)取向、無取向和低碳電工鋼新牌號。1986年日本鋼管公司生產(chǎn)出硅含量為6.5%的高產(chǎn)品。中國1954年生產(chǎn)熱軋，1959年制成并生產(chǎn)了冷軋取向薄帶，1979年生產(chǎn)冷軋取向和無取向。世界電工鋼年產(chǎn)量在600萬t以上，占鋼材總產(chǎn)量的0.9%～1.3%。日本、前蘇聯(lián)和美國年產(chǎn)量都超過100萬t，其中取向約占25%，低碳低硅電工鋼約占65%。性能特點(diǎn)播報(bào)編輯以鐵芯損耗(簡稱鐵損)和磁感應(yīng)強(qiáng)度(簡稱磁感)作為產(chǎn)品磁性保證值。鐵損低可節(jié)省大量電能，延長電機(jī)和變壓器工作運(yùn)轉(zhuǎn)時(shí)間和簡化冷卻系統(tǒng)。由于鐵損造成的電量損失占全年發(fā)電量的2.5%～4.5%，其中變壓器鐵損約占50%，1～100kW小型電機(jī)約占30%，日光燈鎮(zhèn)流器約占15%。磁感高，鐵芯的激磁電流降低，也節(jié)省電能。磁感高可使設(shè)計(jì)的最大磁感(Bm)高、鐵芯體積小、重量輕，節(jié)省、導(dǎo)線、絕緣材料和結(jié)構(gòu)材料等，既使電機(jī)和變壓器損耗和制造成本降低，又便于組裝和運(yùn)輸。由帶齒圓形沖片疊成鐵芯的電機(jī)在運(yùn)轉(zhuǎn)狀態(tài)下工作。要求板為磁各向同性，用無取向制造。由條片疊成鐵芯或由條帶卷繞成鐵芯的變壓器在靜止?fàn)顟B(tài)下工作，用磁各向異性大的冷軋取向制造。此外，要求具有好的沖剪性，表面光滑平整和厚度均勻，好的絕緣膜和磁時(shí)效小。分類播報(bào)編輯按制造工藝和用途電工鋼分為熱軋、冷軋電工鋼和特殊用途三大類，其硅含量、規(guī)格和主要用途見表1。表1
