前不久，由攀鋼研制的大功(gong)率(lv)電爐(lu)用(yong)(yong)高性能Cr20Ni80電熱合金(jin)線材產品試用(yong)(yong)周期超過一年，使用(yong)(yong)壽命(ming)高出國(guo)內同行業(ye)平均水平40%以(yi)上，其他綜(zong)合指標(biao)(biao)也獲得試用(yong)(yong)客戶好評(ping)。經客戶論證，成(cheng)功(gong)獲得可(ke)參與招標(biao)(biao)的合格供貨商資(zi)格。

據悉，Cr20Ni80電(dian)(dian)熱合金具有熔點(dian)高、電(dian)(dian)阻(zu)率(lv)高、電(dian)(dian)阻(zu)溫(wen)度系數小、高中低溫(wen)抗氧化性(xing)能好等特點(dian)，多用(yong)于(yu)生產(chan)電(dian)(dian)熱元(yuan)(yuan)件(jian)(jian)、高中溫(wen)電(dian)(dian)阻(zu)元(yuan)(yuan)件(jian)(jian)、應力測(ce)量元(yuan)(yuan)件(jian)(jian)和(he)特殊元(yuan)(yuan)件(jian)(jian)等，是電(dian)(dian)氣(qi)領(ling)域重(zhong)要的基(ji)礎材料。

我國(guo)(guo)(guo)是電(dian)(dian)熱(re)合(he)金(jin)(jin)的主要消耗國(guo)(guo)(guo)，國(guo)(guo)(guo)內(nei)(nei)電(dian)(dian)熱(re)合(he)金(jin)(jin)生(sheng)(sheng)產(chan)(chan)(chan)企業(ye)以中小型(xing)民營企業(ye)為主。與進(jin)口(kou)產(chan)(chan)(chan)品(pin)相比，國(guo)(guo)(guo)產(chan)(chan)(chan)電(dian)(dian)熱(re)合(he)金(jin)(jin)產(chan)(chan)(chan)品(pin)在質量、性能(neng)(neng)(neng)及使用壽命上均存(cun)在較大差距。基于國(guo)(guo)(guo)內(nei)(nei)產(chan)(chan)(chan)業(ye)升級與進(jin)口(kou)替代的強烈(lie)需求，攀(pan)鋼科研人員從材(cai)料設計出發，系統研究合(he)金(jin)(jin)成(cheng)分、冶(ye)煉工(gong)(gong)藝、加工(gong)(gong)工(gong)(gong)藝及熱(re)處理工(gong)(gong)藝等因素對Cr20Ni80電(dian)(dian)熱(re)合(he)金(jin)(jin)性能(neng)(neng)(neng)的影響規律，深(shen)度優化(hua)Cr20Ni80電(dian)(dian)熱(re)合(he)金(jin)(jin)成(cheng)分及全流(liu)程生(sheng)(sheng)產(chan)(chan)(chan)工(gong)(gong)藝。經(jing)多輪次(ci)實驗(yan)室(shi)小錠型(xing)試(shi)(shi)驗(yan)驗(yan)證(zheng)和數(shu)值(zhi)模擬驗(yan)證(zheng)后，通過工(gong)(gong)業(ye)試(shi)(shi)制(zhi)，成(cheng)功打通大功率電(dian)(dian)爐用高性能(neng)(neng)(neng)Cr20Ni80電(dian)(dian)熱(re)合(he)金(jin)(jin)線材(cai)產(chan)(chan)(chan)品(pin)生(sheng)(sheng)產(chan)(chan)(chan)全流(liu)程工(gong)(gong)藝，首次(ci)完成(cheng)噸級成(cheng)品(pin)試(shi)(shi)制(zhi)，產(chan)(chan)(chan)品(pin)質量達(da)標，綜合(he)性能(neng)(neng)(neng)達(da)到國(guo)(guo)(guo)內(nei)(nei)領先水平。
