“十三五”期間我國電工鋼產業發展碩果累累

      我(wo)(wo)國(guo)電(dian)(dian)(dian)工(gong)鋼(gang)產(chan)業(ye)在生產(chan)規(gui)模、技術進步(bu)、進出口數量等方面均取(qu)得了(le)不錯的成績(ji),為國(guo)家經濟建(jian)設(she)做出了(le)巨大貢(gong)獻,助力了(le)多個重點工(gong)程建(jian)設(she),如昌(chang)吉(ji)—古泉±1100千伏特高(gao)壓直流輸電(dian)(dian)(dian)工(gong)程,北京(jing)正負電(dian)(dian)(dian)子對撞機(ji)工(gong)程,神六(liu)、神七載人飛船工(gong)程等。”在采訪(fang)中(zhong),陳(chen)卓特別興奮(fen)地向《中(zhong)國(guo)冶(ye)金(jin)報》記者介紹了(le)我(wo)(wo)國(guo)電(dian)(dian)(dian)工(gong)鋼(gang)產(chan)業(ye)在“十三五”期間取(qu)得的成就,言語中(zhong)流露出自豪之情。


       一是(shi)生產(chan)規模持續擴大。從產(chan)能(neng)來看(kan),在“十(shi)三五”期(qi)(qi)間,我(wo)(wo)國(guo)電(dian)工(gong)鋼(gang)產(chan)能(neng)連續5年(nian)突破千萬(wan)(wan)(wan)噸(dun)。2020年(nian),我(wo)(wo)國(guo)電(dian)工(gong)鋼(gang)產(chan)能(neng)已達到1276萬(wan)(wan)(wan)噸(dun),是(shi)1978年(nian)剛投(tou)產(chan)時的181倍,其中(zhong)無取向(xiang)電(dian)工(gong)鋼(gang)產(chan)能(neng)為(wei)1096萬(wan)(wan)(wan)噸(dun),比“十(shi)二五”期(qi)(qi)間的平均(jun)(jun)值(zhi)增(zeng)長了19.78%,取向(xiang)電(dian)工(gong)鋼(gang)產(chan)能(neng)為(wei)180萬(wan)(wan)(wan)噸(dun),比“十(shi)二五”期(qi)(qi)間的平均(jun)(jun)值(zhi)增(zeng)長了125%。根據(ju)2019年(nian)全(quan)球產(chan)能(neng)數據(ju),我(wo)(wo)國(guo)電(dian)工(gong)鋼(gang)產(chan)能(neng)約占全(quan)球電(dian)工(gong)鋼(gang)總產(chan)能(neng)的65.16%。


      從(cong)產量(liang)(liang)來看,我(wo)國電(dian)工鋼(gang)產量(liang)(liang)在“十(shi)(shi)三五”期(qi)間(jian)(jian)連續(xu)4年突破千萬(wan)噸(dun)。2020年,我(wo)國電(dian)工鋼(gang)產量(liang)(liang)已(yi)達到(dao)1118.11萬(wan)噸(dun)。在“十(shi)(shi)三五”期(qi)間(jian)(jian),我(wo)國共生(sheng)產無取向(xiang)電(dian)工鋼(gang)約(yue)(yue)4433.52萬(wan)噸(dun),與(yu)“十(shi)(shi)二五”期(qi)間(jian)(jian)相比增長(chang)(chang)36.56%;生(sheng)產取向(xiang)電(dian)工鋼(gang)約(yue)(yue)645.28萬(wan)噸(dun),與(yu)“十(shi)(shi)二五”期(qi)間(jian)(jian)相比增長(chang)(chang)39.42%。無取向(xiang)電(dian)工鋼(gang)產能平均(jun)利用率為82.55%,取向(xiang)電(dian)工鋼(gang)產能平均(jun)利用率為82.22%,均(jun)在合(he)理區間(jian)(jian)。根據2019年全(quan)球(qiu)(qiu)產量(liang)(liang)數據,我(wo)國電(dian)工鋼(gang)產量(liang)(liang)約(yue)(yue)占(zhan)全(quan)球(qiu)(qiu)電(dian)工鋼(gang)總產量(liang)(liang)的(de)68.54%。


      二(er)(er)是品(pin)種結構不斷(duan)優(you)化,技術不斷(duan)進步。在“十三(san)五”期間(jian),我國(guo)共生產(chan)高(gao)端電(dian)(dian)工(gong)(gong)鋼(gang)(gang)1273.8萬(wan)噸,與(yu)“十二(er)(er)五”期間(jian)相比(bi)增長90.28%。其(qi)中,高(gao)牌(pai)(pai)號(高(gao)效(xiao))無(wu)(wu)取(qu)(qu)向(xiang)電(dian)(dian)工(gong)(gong)鋼(gang)(gang)生產(chan)約830.14萬(wan)噸、增長114.9%;高(gao)磁(ci)感取(qu)(qu)向(xiang)電(dian)(dian)工(gong)(gong)鋼(gang)(gang)(HiB)生產(chan)約443.66萬(wan)噸、增長56.68%。“十三(san)五”期末,即2020年,我國(guo)高(gao)牌(pai)(pai)號無(wu)(wu)取(qu)(qu)向(xiang)電(dian)(dian)工(gong)(gong)鋼(gang)(gang)產(chan)量(liang)為200.29萬(wan)噸,占無(wu)(wu)取(qu)(qu)向(xiang)電(dian)(dian)工(gong)(gong)鋼(gang)(gang)總(zong)產(chan)量(liang)的20.85%;高(gao)磁(ci)感取(qu)(qu)向(xiang)電(dian)(dian)工(gong)(gong)鋼(gang)(gang)(HiB)產(chan)量(liang)為92.51萬(wan)噸,占取(qu)(qu)向(xiang)電(dian)(dian)工(gong)(gong)鋼(gang)(gang)總(zong)產(chan)量(liang)的58.69%。“十三(san)五”期末(2020年)與(yu)“十二(er)(er)五”期末(2015年)相比(bi),高(gao)牌(pai)(pai)號無(wu)(wu)取(qu)(qu)向(xiang)電(dian)(dian)工(gong)(gong)鋼(gang)(gang)、高(gao)磁(ci)感取(qu)(qu)向(xiang)電(dian)(dian)工(gong)(gong)鋼(gang)(gang)(HiB)產(chan)量(liang)分別增長78.48%、11.92%。


      “目前,我(wo)國(guo)電工鋼生(sheng)產(chan)能力已實現了從低端到(dao)中端、再(zai)到(dao)高端產(chan)品(pin)(pin)(pin)的全覆蓋,且產(chan)品(pin)(pin)(pin)表面質量、板形(xing)尺寸精度、產(chan)品(pin)(pin)(pin)包裝等均可與國(guo)外同類產(chan)品(pin)(pin)(pin)相媲美。”陳卓告訴《中國(guo)冶金報》記者。


      三是從凈進(jin)(jin)口(kou)(kou)國成(cheng)為凈出口(kou)(kou)國。在“十三五”期間(jian)(jian)(jian),我國共進(jin)(jin)口(kou)(kou)電(dian)(dian)工鋼215萬(wan)噸(dun),與(yu)(yu)“十二(er)五”期間(jian)(jian)(jian)相(xiang)比(bi)下(xia)(xia)降36.40%。其中,進(jin)(jin)口(kou)(kou)無取向電(dian)(dian)工鋼197.18萬(wan)噸(dun),與(yu)(yu)“十二(er)五”期間(jian)(jian)(jian)相(xiang)比(bi)下(xia)(xia)降20.97%;進(jin)(jin)口(kou)(kou)取向電(dian)(dian)工鋼17.82萬(wan)噸(dun),與(yu)(yu)“十二(er)五”期間(jian)(jian)(jian)相(xiang)比(bi)下(xia)(xia)降81.47%。

在(zai)“十(shi)三(san)五”期間(jian),我國(guo)共出(chu)口(kou)電工(gong)鋼243.41萬噸(dun),與(yu)“十(shi)二(er)五”期間(jian)相比增長60.59%。其中,出(chu)口(kou)無取(qu)(qu)向(xiang)電工(gong)鋼153.7萬噸(dun),與(yu)“十(shi)二(er)五”期間(jian)相比增長24.10%;出(chu)口(kou)取(qu)(qu)向(xiang)電工(gong)鋼89.71萬噸(dun),與(yu)“十(shi)二(er)五”期間(jian)相比增長223.63%。



     “其中(zhong),2017年(nian),我國從電工鋼凈(jing)進口國成為凈(jing)出口國,完全擺(bai)脫了長(chang)期依賴進口的(de)局(ju)面。”陳卓(zhuo)說道。


      此外(wai),在申(shen)(shen)請專(zhuan)(zhuan)(zhuan)利(li)(li)方面,陳卓介紹,我國電工鋼(gang)在“十二五”期間(jian)(jian)申(shen)(shen)請發明(ming)(ming)(ming)(ming)專(zhuan)(zhuan)(zhuan)利(li)(li)466件、實(shi)用(yong)新型(xing)(xing)專(zhuan)(zhuan)(zhuan)利(li)(li)44件,在“十三(san)五”期間(jian)(jian)申(shen)(shen)請發明(ming)(ming)(ming)(ming)專(zhuan)(zhuan)(zhuan)利(li)(li)367件、實(shi)用(yong)新型(xing)(xing)專(zhuan)(zhuan)(zhuan)利(li)(li)54件,10年累計申(shen)(shen)請發明(ming)(ming)(ming)(ming)專(zhuan)(zhuan)(zhuan)利(li)(li)833件、實(shi)用(yong)新型(xing)(xing)專(zhuan)(zhuan)(zhuan)利(li)(li)98件,為電工鋼(gang)產業技術(shu)進步(bu)、創(chuang)新發展發揮了重要作用(yong)。“其中,有些發明(ming)(ming)(ming)(ming)專(zhuan)(zhuan)(zhuan)利(li)(li)和實(shi)用(yong)專(zhuan)(zhuan)(zhuan)利(li)(li)技術(shu)已走在世界前(qian)列。”(來源:中國冶(ye)金報(bao))
