日(ri)前，鞍鋼獨家(jia)中標國家(jia)重(zhong)點工程(cheng)——中俄原油管道二(er)線(xian)工程(cheng)（又稱漠(mo)大復線(xian)）全部4個標段的(de)X65M熱軋(ya)卷板(ban)和(he)熱軋(ya)平(ping)板(ban)，總計25萬噸(dun)。這為中俄戰略協作(zuo)伙伴(ban)關系建立(li)20周年添上喜慶的(de)一筆(bi)。
中俄原(yuan)油管(guan)道(dao)(dao)工(gong)程是(shi)我國(guo)(guo)正在(zai)(zai)構建(jian)的(de)東北、西北、西南和海(hai)上四大能源戰略通(tong)道(dao)(dao)之一。中俄原(yuan)油管(guan)道(dao)(dao)二(er)線(xian)工(gong)程是(shi)近(jin)三(san)年(nian)國(guo)(guo)內最(zui)大管(guan)道(dao)(dao)工(gong)程，始(shi)于(yu)漠河縣，止于(yu)大慶市，全長941.8公里，全線(xian)采用(yong)X65M螺旋縫埋弧(hu)焊鋼(gang)管(guan)和直縫埋弧(hu)焊鋼(gang)管(guan)。計劃2017年(nian)建(jian)成投產，建(jian)成后將(jiang)成為我國(guo)(guo)北方(fang)重要(yao)的(de)油氣戰略通(tong)道(dao)(dao)。工(gong)程地處高寒(han)地區，最(zui)低(di)氣溫達零下58.2攝氏(shi)度(du)，其工(gong)程技術難度(du)大、要(yao)求(qiu)高。特別是(shi)對管(guan)道(dao)(dao)原(yuan)材料即制管(guan)用(yong)卷板(ban)(ban)和平板(ban)(ban)的(de)要(yao)求(qiu)，低(di)溫韌性要(yao)求(qiu)遠遠高于(yu)常規管(guan)線(xian)鋼(gang)，其落錘試驗(yan)溫度(du)為零下25攝氏(shi)度(du)，低(di)溫韌脆轉變(bian)溫度(du)要(yao)求(qiu)在(zai)(zai)零下40攝氏(shi)度(du)以下。
管(guan)(guan)(guan)線(xian)(xian)(xian)(xian)(xian)鋼(gang)(gang)是(shi)鞍鋼(gang)(gang)的(de)戰略品(pin)(pin)牌產(chan)品(pin)(pin)，已具備X80鋼(gang)(gang)級(ji)以(yi)下管(guan)(guan)(guan)線(xian)(xian)(xian)(xian)(xian)鋼(gang)(gang)產(chan)品(pin)(pin)品(pin)(pin)種(zhong)和規格的(de)全覆蓋(gai)，可滿(man)足(zu)國內外管(guan)(guan)(guan)線(xian)(xian)(xian)(xian)(xian)工程各種(zhong)鋼(gang)(gang)材需求。在西氣東輸、陜京二(er)線(xian)(xian)(xian)(xian)(xian)、川氣東送、中俄原油管(guan)(guan)(guan)道一線(xian)(xian)(xian)(xian)(xian)、沿海LNG管(guan)(guan)(guan)線(xian)(xian)(xian)(xian)(xian)、南海荔灣管(guan)(guan)(guan)線(xian)(xian)(xian)(xian)(xian)等(deng)國家重點工程中，鞍鋼(gang)(gang)管(guan)(guan)(guan)線(xian)(xian)(xian)(xian)(xian)鋼(gang)(gang)均作(zuo)出過重要貢(gong)獻。面對中俄原油管(guan)(guan)(guan)道二(er)線(xian)(xian)(xian)(xian)(xian)工程對產(chan)品(pin)(pin)的(de)苛(ke)刻要求，鞍鋼(gang)(gang)也(ye)是(shi)以(yi)實力說話，最終(zhong)以(yi)完(wan)善的(de)產(chan)品(pin)(pin)設計方案和產(chan)品(pin)(pin)試(shi)制生產(chan)計劃順利中標(biao)。
目前，鞍(an)鋼(gang)針對漠大(da)復(fu)線(xian)(xian)工(gong)程(cheng)用卷(juan)板和平板的試制(zhi)工(gong)作，已分(fen)別在(zai)鞍(an)鋼(gang)股份熱軋帶鋼(gang)廠2150ASP生(sheng)產(chan)(chan)線(xian)(xian)、中厚板廠4300毫(hao)(hao)米生(sheng)產(chan)(chan)線(xian)(xian)、鲅(ba)魚圈分(fen)公(gong)司 5500毫(hao)(hao)米生(sheng)產(chan)(chan)線(xian)(xian)等三條生(sheng)產(chan)(chan)線(xian)(xian)有序開展，待試制(zhi)產(chan)(chan)品檢驗合格后將(jiang)進行(xing)制(zhi)管(guan)試制(zhi)，保證供貨質量，讓中俄原(yuan)油管(guan)道二線(xian)(xian)工(gong)程(cheng)成為(wei)鞍(an)鋼(gang)管(guan)線(xian)(xian)鋼(gang)的又一精品工(gong)程(cheng)。
