日前，中(zhong)南鋼鐵中(zhong)南股份成(cheng)功簽訂一批出口阿爾及利亞(ya)的LNG（液化天(tian)然氣）低溫鋼筋訂單，實(shi)現了低溫鋼筋出口零的突破。目前產品已(yi)完(wan)成(cheng)生(sheng)產和檢測(ce)，正等待船(chuan)舶信息以完(wan)成(cheng)交(jiao)貨(huo)。

  天然氣作為一(yi)種清潔(jie)能源，在優化(hua)能源消費結(jie)(jie)構(gou)、控制溫(wen)(wen)(wen)(wen)(wen)(wen)室氣體排放(fang)、改善大氣環境(jing)等方面(mian)發(fa)揮重要作用(yong)。低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)(wen)(wen)鋼(gang)(gang)筋(jin)(jin)作為LNG儲罐的(de)主要結(jie)(jie)構(gou)材料，在-165℃超低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)(wen)(wen)下(xia)具有高(gao)強(qiang)度(du)、良好(hao)韌(ren)性及耐腐蝕(shi)性、足夠的(de)抗脆性開裂(lie)和止裂(lie)能。低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)(wen)(wen)鋼(gang)(gang)筋(jin)(jin)生(sheng)產難(nan)度(du)大，低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)(wen)(wen)性能檢(jian)(jian)測(ce)也是一(yi)個難(nan)題，需在-165℃下(xia)檢(jian)(jian)測(ce)鋼(gang)(gang)筋(jin)(jin)的(de)低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)(wen)(wen)拉(la)伸性能。中南股份于2015年(nian)(nian)開始研(yan)究低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)(wen)(wen)鋼(gang)(gang)筋(jin)(jin)，2016年(nian)(nian)牽頭開展(zhan)廣東省應用(yong)型(xing)科技研(yan)發(fa)專(zhuan)項資金項目“超低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)(wen)(wen)環境(jing)友好(hao)型(xing)高(gao)強(qiang)鋼(gang)(gang)筋(jin)(jin)關鍵技術(shu)研(yan)究及產業(ye)化(hua)”。經(jing)過多年(nian)(nian)努力，中南股份現已成為國內低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)(wen)(wen)鋼(gang)(gang)筋(jin)(jin)生(sheng)產廠家(jia)“三駕(jia)馬車(che)”之一(yi)。2022年(nian)(nian)3月，中南股份檢(jian)(jian)測(ce)中心獲得(de)LNG低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)(wen)(wen)鋼(gang)(gang)筋(jin)(jin)低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)(wen)(wen)拉(la)伸檢(jian)(jian)測(ce)能力CMA（中國檢(jian)(jian)測(ce)機(ji)構(gou)和實驗室強(qiang)制認(ren)證）資質認(ren)定證書，成為全國極(ji)少數具備此(ci)項檢(jian)(jian)測(ce)能力認(ren)定的(de)實驗室。

  中(zhong)南股份LNG儲(chu)罐用低溫鋼(gang)(gang)筋(jin)已廣泛應(ying)用到國(guo)內(nei)能源龍頭企業(ye)(ye)的LNG儲(chu)罐建設項(xiang)目，取得良好成效(xiao)，并創造兩個第(di)一：應(ying)用到全(quan)球容積最(zui)大(da)(da)的27萬立(li)方米(mi)LNG儲(chu)罐，實現(xian)產(chan)業(ye)(ye)化并推廣應(ying)用了目前(qian)最(zui)大(da)(da)規格直(zhi)徑28毫米(mi)低溫鋼(gang)(gang)筋(jin)。

  中南股份成功(gong)簽訂(ding)首筆LNG儲罐用低溫鋼筋出口訂(ding)單，表明(ming)該產品(pin)已得(de)到國外項(xiang)目認可，對(dui)提高產品(pin)國際競爭力有(you)積極作(zuo)用。
