日前，中南鋼(gang)鐵中南股份成(cheng)功簽訂一(yi)批出口(kou)阿爾及利(li)亞的LNG（液化天然氣）低溫鋼(gang)筋(jin)訂單(dan)，實現了低溫鋼(gang)筋(jin)出口(kou)零的突破(po)。目前產(chan)品已(yi)完成(cheng)生(sheng)產(chan)和檢測(ce)，正等待船舶(bo)信息(xi)以完成(cheng)交貨。

  天然氣作為一(yi)種(zhong)清(qing)潔能(neng)源(yuan)，在(zai)優(you)化(hua)(hua)能(neng)源(yuan)消費(fei)結(jie)構、控制溫(wen)(wen)(wen)(wen)(wen)室(shi)(shi)氣體排放、改善大氣環境等(deng)方面發(fa)揮(hui)重要作用(yong)。低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)(wen)鋼(gang)筋(jin)作為LNG儲罐的主要結(jie)構材(cai)料(liao)，在(zai)-165℃超低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)(wen)下具(ju)有高(gao)強(qiang)度(du)、良(liang)好韌性(xing)及耐(nai)腐蝕(shi)性(xing)、足夠的抗(kang)脆性(xing)開(kai)裂和止裂能(neng)。低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)(wen)鋼(gang)筋(jin)生產難(nan)度(du)大，低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)(wen)性(xing)能(neng)檢(jian)(jian)測也(ye)是一(yi)個難(nan)題(ti)，需在(zai)-165℃下檢(jian)(jian)測鋼(gang)筋(jin)的低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)(wen)拉(la)伸(shen)性(xing)能(neng)。中南股(gu)份于2015年(nian)開(kai)始研(yan)究低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)(wen)鋼(gang)筋(jin)，2016年(nian)牽頭開(kai)展廣(guang)東省應用(yong)型科技研(yan)發(fa)專項(xiang)資金項(xiang)目“超低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)(wen)環境友(you)好型高(gao)強(qiang)鋼(gang)筋(jin)關鍵(jian)技術研(yan)究及產業化(hua)(hua)”。經過多年(nian)努力(li)，中南股(gu)份現已成為國(guo)內低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)(wen)鋼(gang)筋(jin)生產廠家(jia)“三駕馬車”之一(yi)。2022年(nian)3月，中南股(gu)份檢(jian)(jian)測中心獲得LNG低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)(wen)鋼(gang)筋(jin)低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)(wen)拉(la)伸(shen)檢(jian)(jian)測能(neng)力(li)CMA（中國(guo)檢(jian)(jian)測機構和實(shi)驗室(shi)(shi)強(qiang)制認證）資質認定證書，成為全國(guo)極少數具(ju)備此(ci)項(xiang)檢(jian)(jian)測能(neng)力(li)認定的實(shi)驗室(shi)(shi)。

  中南股份(fen)LNG儲罐用低溫鋼筋已廣泛應(ying)用到國(guo)內能源龍頭企業的LNG儲罐建設項(xiang)目(mu)，取(qu)得良(liang)好成效，并創造兩個第(di)一：應(ying)用到全(quan)球(qiu)容(rong)積最大的27萬立方米(mi)LNG儲罐，實現產業化(hua)并推廣應(ying)用了目(mu)前最大規格直(zhi)徑28毫米(mi)低溫鋼筋。

  中南股份成(cheng)功簽訂(ding)首(shou)筆LNG儲(chu)罐(guan)用(yong)(yong)低溫鋼筋出口訂(ding)單，表明該產(chan)品(pin)已得(de)到國(guo)外項目認可，對提高產(chan)品(pin)國(guo)際競爭(zheng)力有積極作用(yong)(yong)。
