國外變(bian)壓器用(yong)電(dian)工(gong)鋼(gang)(gang)(gang)(gang)的(de)專業(ye)(ye)深(shen)加工(gong)產業(ye)(ye)鏈早在幾十年前就已經形成，并發(fa)展的(de)非常完(wan)善，電(dian)工(gong)鋼(gang)(gang)(gang)(gang)加工(gong)均由(you)專業(ye)(ye)的(de)深(shen)加工(gong)企業(ye)(ye)完(wan)成。但在我(wo)國，很多年來變(bian)壓器用(yong)電(dian)工(gong)鋼(gang)(gang)(gang)(gang)的(de)深(shen)加工(gong)一直沒有形成專業(ye)(ye)的(de)產業(ye)(ye)鏈，電(dian)工(gong)鋼(gang)(gang)(gang)(gang)的(de)深(shen)加工(gong)基本都(dou)是由(you)變(bian)壓器制造(zao)廠家去做(zuo)，這樣也導致了變(bian)壓器用(yong)電(dian)工(gong)鋼(gang)(gang)(gang)(gang)的(de)深(shen)加工(gong)技術發(fa)展比較緩慢(man)。

       直到近十幾(ji)年(nian)，越來越多的(de)(de)變壓器(qi)(qi)制造商將電(dian)(dian)工(gong)(gong)鋼(gang)(gang)加(jia)工(gong)(gong)交(jiao)由專(zhuan)業(ye)(ye)(ye)(ye)的(de)(de)深(shen)加(jia)工(gong)(gong)變壓鐵(tie)心企業(ye)(ye)(ye)(ye)來完(wan)成(cheng)，這樣才促進變壓器(qi)(qi)用(yong)電(dian)(dian)工(gong)(gong)鋼(gang)(gang)專(zhuan)業(ye)(ye)(ye)(ye)深(shen)加(jia)工(gong)(gong)產業(ye)(ye)(ye)(ye)鏈逐漸形(xing)成(cheng)。專(zhuan)業(ye)(ye)(ye)(ye)深(shen)加(jia)工(gong)(gong)產業(ye)(ye)(ye)(ye)鏈的(de)(de)形(xing)成(cheng)也推(tui)進了(le)電(dian)(dian)工(gong)(gong)鋼(gang)(gang)深(shen)加(jia)工(gong)(gong)技術的(de)(de)發展，同時也促進了(le)我國電(dian)(dian)工(gong)(gong)裝備制造業(ye)(ye)(ye)(ye)的(de)(de)發展，尤其近幾(ji)年(nian)，硅(gui)鋼(gang)(gang)縱剪(jian)線(xian)、硅(gui)鋼(gang)(gang)片(pian)橫(heng)剪(jian)線(xian)的(de)(de)技術進步非常快(kuai)，思瑞品牌系列硅(gui)鋼(gang)(gang)片(pian)橫(heng)剪(jian)線(xian)迎頭趕上，快(kuai)速崛起，在行業(ye)(ye)(ye)(ye)內(nei)(nei)形(xing)成(cheng)一定的(de)(de)市場規(gui)模。據不完(wan)全(quan)(quan)統計，2020年(nian)全(quan)(quan)國生(sheng)產變壓器(qi)(qi)用(yong)電(dian)(dian)工(gong)(gong)鋼(gang)(gang)原卷約為180萬噸，其中近一半是由專(zhuan)業(ye)(ye)(ye)(ye)深(shen)加(jia)工(gong)(gong)企業(ye)(ye)(ye)(ye)加(jia)工(gong)(gong)成(cheng)變壓器(qi)(qi)鐵(tie)心成(cheng)品。但目前在國內(nei)(nei)眾多專(zhuan)業(ye)(ye)(ye)(ye)化(hua)深(shen)加(jia)工(gong)(gong)企業(ye)(ye)(ye)(ye)中只有(you)極(ji)少數企業(ye)(ye)(ye)(ye)做(zuo)的(de)(de)比較完(wan)善，他們在如何將電(dian)(dian)工(gong)(gong)鋼(gang)(gang)材(cai)料本身性能發揮到最大(da)(da)方面做(zuo)了(le)很大(da)(da)的(de)(de)努(nu)力，效果也比較好。其可以實現從電(dian)(dian)工(gong)(gong)鋼(gang)(gang)原材(cai)料入庫(ku)開始直至鐵(tie)心成(cheng)品疊裝完(wan)成(cheng)的(de)(de)全(quan)(quan)流(liu)程自動化(hua)，過程中電(dian)(dian)工(gong)(gong)鋼(gang)(gang)全(quan)(quan)部(bu)采用(yong)“軟接觸”，全(quan)(quan)程無(wu)行車吊運、無(wu)人員(yuan)參與(yu)直接生(sheng)產、無(wu)人員(yuan)觸碰電(dian)(dian)工(gong)(gong)鋼(gang)(gang)，隨著《GB∕T 32288-2020 電(dian)力變(bian)壓(ya)(ya)器(qi)用(yong)電(dian)工(gong)(gong)鋼(gang)鐵(tie)(tie)(tie)心》正式實施，該標準代替《GB∕T 32288-2015 電(dian)力變(bian)壓(ya)(ya)器(qi)用(yong)電(dian)工(gong)(gong)鋼(gang)鐵(tie)(tie)(tie)心》，規定(ding)了(le)電(dian)力變(bian)壓(ya)(ya)器(qi)用(yong)電(dian)工(gong)(gong)鋼(gang)鐵(tie)(tie)(tie)芯的(de)型號表示方(fang)法，技術要(yao)求(qiu)、試驗方(fang)法、檢(jian)驗規則，標志(zhi)、包裝(zhuang)和(he)檢(jian)驗存(cun)儲。對于電(dian)力變(bian)壓(ya)(ya)器(qi)用(yong)電(dian)工(gong)(gong)鋼(gang)疊鐵(tie)(tie)(tie)芯提出更高的(de)要(yao)求(qiu)，同時也對電(dian)工(gong)(gong)裝(zhuang)備(bei)(bei)(bei)制造業(ye)中硅鋼(gang)縱(zong)剪(jian)設備(bei)(bei)(bei)、橫(heng)剪(jian)設備(bei)(bei)(bei)、鐵(tie)(tie)(tie)心自動疊裝(zhuang)設備(bei)(bei)(bei)提出了(le)更高的(de)要(yao)求(qiu)。
