日前，中南(nan)(nan)鋼鐵中南(nan)(nan)股份成功簽訂(ding)一批出口阿(a)爾(er)及利亞的(de)LNG（液化天(tian)然氣）低溫(wen)鋼筋訂(ding)單，實(shi)現了低溫(wen)鋼筋出口零的(de)突破。目前產品已完(wan)成生產和檢測(ce)，正等(deng)待船舶(bo)信息以(yi)完(wan)成交(jiao)貨。

  天然氣作(zuo)為(wei)(wei)(wei)一(yi)種清潔能源(yuan)，在(zai)優化(hua)能源(yuan)消費結(jie)構(gou)、控(kong)制溫(wen)(wen)(wen)(wen)室(shi)氣體排放、改善大氣環(huan)(huan)境等方面發(fa)揮重要作(zuo)用(yong)。低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)鋼(gang)(gang)筋(jin)作(zuo)為(wei)(wei)(wei)LNG儲罐的(de)主要結(jie)構(gou)材料，在(zai)-165℃超(chao)低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)下(xia)具有高(gao)(gao)強度、良好韌性(xing)(xing)及耐腐蝕性(xing)(xing)、足夠的(de)抗脆性(xing)(xing)開裂和止裂能。低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)鋼(gang)(gang)筋(jin)生(sheng)產難度大，低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)性(xing)(xing)能檢(jian)(jian)測(ce)也是一(yi)個(ge)難題，需(xu)在(zai)-165℃下(xia)檢(jian)(jian)測(ce)鋼(gang)(gang)筋(jin)的(de)低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)拉伸(shen)性(xing)(xing)能。中南(nan)股(gu)份(fen)于(yu)2015年(nian)(nian)(nian)開始研(yan)(yan)究(jiu)低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)鋼(gang)(gang)筋(jin)，2016年(nian)(nian)(nian)牽頭開展(zhan)廣東(dong)省應(ying)用(yong)型科(ke)技研(yan)(yan)發(fa)專項資金(jin)項目“超(chao)低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)環(huan)(huan)境友好型高(gao)(gao)強鋼(gang)(gang)筋(jin)關鍵技術研(yan)(yan)究(jiu)及產業化(hua)”。經過(guo)多年(nian)(nian)(nian)努力(li)，中南(nan)股(gu)份(fen)現已成為(wei)(wei)(wei)國(guo)(guo)內低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)鋼(gang)(gang)筋(jin)生(sheng)產廠家“三駕(jia)馬車”之一(yi)。2022年(nian)(nian)(nian)3月，中南(nan)股(gu)份(fen)檢(jian)(jian)測(ce)中心獲(huo)得(de)LNG低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)鋼(gang)(gang)筋(jin)低(di)(di)(di)(di)溫(wen)(wen)(wen)(wen)拉伸(shen)檢(jian)(jian)測(ce)能力(li)CMA（中國(guo)(guo)檢(jian)(jian)測(ce)機(ji)構(gou)和實驗(yan)室(shi)強制認(ren)(ren)證）資質認(ren)(ren)定證書，成為(wei)(wei)(wei)全國(guo)(guo)極(ji)少數(shu)具備(bei)此項檢(jian)(jian)測(ce)能力(li)認(ren)(ren)定的(de)實驗(yan)室(shi)。

  中南股份LNG儲罐(guan)用低(di)溫(wen)(wen)鋼筋已廣泛(fan)應(ying)用到國內能源龍頭企業(ye)的LNG儲罐(guan)建設項目(mu)，取得良(liang)好成效(xiao)，并創造(zao)兩個(ge)第一：應(ying)用到全(quan)球(qiu)容積(ji)最(zui)大的27萬立(li)方米(mi)LNG儲罐(guan)，實現產業(ye)化并推廣應(ying)用了目(mu)前最(zui)大規格直徑28毫米(mi)低(di)溫(wen)(wen)鋼筋。

  中南股(gu)份成功(gong)簽(qian)訂首筆LNG儲(chu)罐用低溫鋼(gang)筋出口訂單(dan)，表明該(gai)產品已得到國外(wai)項目認可，對提高產品國際競爭力有(you)積極作用。
