日前，鞍鋼獨家(jia)中(zhong)標國家(jia)重(zhong)點工程——中(zhong)俄原油管道二線工程（又稱漠(mo)大復線）全(quan)部4個(ge)標段的(de)X65M熱軋卷(juan)板(ban)和熱軋平板(ban)，總計25萬噸。這為中(zhong)俄戰略協(xie)作伙伴(ban)關系(xi)建(jian)立20周(zhou)年添上喜慶的(de)一筆。
中(zhong)俄(e)原(yuan)油管(guan)(guan)道(dao)(dao)工(gong)程是我(wo)國(guo)正在(zai)構建(jian)的(de)(de)東北、西北、西南(nan)和(he)海上四(si)大(da)能源(yuan)戰略通(tong)道(dao)(dao)之一。中(zhong)俄(e)原(yuan)油管(guan)(guan)道(dao)(dao)二線工(gong)程是近三(san)年(nian)國(guo)內(nei)最大(da)管(guan)(guan)道(dao)(dao)工(gong)程，始(shi)于漠河縣，止于大(da)慶市，全長941.8公里，全線采用X65M螺旋縫埋弧焊鋼管(guan)(guan)和(he)直縫埋弧焊鋼管(guan)(guan)。計劃(hua)2017年(nian)建(jian)成投產(chan)，建(jian)成后將成為(wei)我(wo)國(guo)北方重要的(de)(de)油氣(qi)戰略通(tong)道(dao)(dao)。工(gong)程地處(chu)高(gao)(gao)寒(han)地區，最低(di)(di)氣(qi)溫(wen)達(da)零下58.2攝(she)氏度(du)，其(qi)工(gong)程技(ji)術難度(du)大(da)、要求(qiu)高(gao)(gao)。特別是對管(guan)(guan)道(dao)(dao)原(yuan)材料即制管(guan)(guan)用卷板和(he)平板的(de)(de)要求(qiu)，低(di)(di)溫(wen)韌(ren)(ren)性要求(qiu)遠遠高(gao)(gao)于常規(gui)管(guan)(guan)線鋼，其(qi)落錘試驗溫(wen)度(du)為(wei)零下25攝(she)氏度(du)，低(di)(di)溫(wen)韌(ren)(ren)脆轉(zhuan)變溫(wen)度(du)要求(qiu)在(zai)零下40攝(she)氏度(du)以(yi)下。
管(guan)(guan)(guan)線鋼(gang)是鞍(an)鋼(gang)的(de)戰略品(pin)(pin)(pin)牌(pai)產(chan)品(pin)(pin)(pin)，已具備X80鋼(gang)級以(yi)下管(guan)(guan)(guan)線鋼(gang)產(chan)品(pin)(pin)(pin)品(pin)(pin)(pin)種和規格(ge)的(de)全覆蓋，可滿足(zu)國內外管(guan)(guan)(guan)線工(gong)(gong)程各種鋼(gang)材需求。在西氣東輸、陜(shan)京二線、川氣東送、中(zhong)俄原油管(guan)(guan)(guan)道一線、沿(yan)海LNG管(guan)(guan)(guan)線、南海荔灣管(guan)(guan)(guan)線等(deng)國家重(zhong)點工(gong)(gong)程中(zhong)，鞍(an)鋼(gang)管(guan)(guan)(guan)線鋼(gang)均作(zuo)出過重(zhong)要(yao)貢(gong)獻。面對中(zhong)俄原油管(guan)(guan)(guan)道二線工(gong)(gong)程對產(chan)品(pin)(pin)(pin)的(de)苛刻要(yao)求，鞍(an)鋼(gang)也是以(yi)實(shi)力(li)說話(hua)，最終以(yi)完善的(de)產(chan)品(pin)(pin)(pin)設計方案和產(chan)品(pin)(pin)(pin)試制生產(chan)計劃順利中(zhong)標。
目(mu)前(qian)，鞍(an)鋼針對漠大復線(xian)工(gong)程用卷(juan)板和平板的試(shi)制(zhi)(zhi)(zhi)工(gong)作，已分(fen)別(bie)在鞍(an)鋼股份(fen)熱軋帶鋼廠2150ASP生(sheng)產線(xian)、中(zhong)(zhong)厚板廠4300毫(hao)米生(sheng)產線(xian)、鲅魚圈(quan)分(fen)公司(si) 5500毫(hao)米生(sheng)產線(xian)等三條生(sheng)產線(xian)有序開(kai)展，待(dai)試(shi)制(zhi)(zhi)(zhi)產品檢(jian)驗合(he)格后將(jiang)進(jin)行制(zhi)(zhi)(zhi)管(guan)試(shi)制(zhi)(zhi)(zhi)，保證供貨質量，讓中(zhong)(zhong)俄原油管(guan)道(dao)二線(xian)工(gong)程成(cheng)為鞍(an)鋼管(guan)線(xian)鋼的又一精品工(gong)程。
