前不久(jiu)，由攀鋼(gang)研制的大功率電爐(lu)用高性能Cr20Ni80電熱合(he)(he)金線材產品試用周期超過一年，使用壽命高出國(guo)內(nei)同行業平均水平40%以上，其他(ta)綜合(he)(he)指標也獲(huo)得試用客戶(hu)好評。經客戶(hu)論(lun)證，成功獲(huo)得可參與招標的合(he)(he)格供貨商資格。

據悉(xi)，Cr20Ni80電(dian)熱合(he)金(jin)具有熔點(dian)高(gao)、電(dian)阻率高(gao)、電(dian)阻溫(wen)度系數小、高(gao)中(zhong)低(di)溫(wen)抗氧(yang)化(hua)性能好等特點(dian)，多(duo)用于(yu)生產電(dian)熱元(yuan)件(jian)、高(gao)中(zhong)溫(wen)電(dian)阻元(yuan)件(jian)、應(ying)力測量元(yuan)件(jian)和(he)特殊元(yuan)件(jian)等，是電(dian)氣(qi)領域重(zhong)要的基礎(chu)材料(liao)。

我(wo)國(guo)(guo)是(shi)電(dian)(dian)熱(re)合(he)金(jin)的(de)主(zhu)要消耗國(guo)(guo)，國(guo)(guo)內電(dian)(dian)熱(re)合(he)金(jin)生產企(qi)業以中(zhong)小型民營企(qi)業為主(zhu)。與進口產品相比，國(guo)(guo)產電(dian)(dian)熱(re)合(he)金(jin)產品在(zai)質量(liang)、性(xing)能(neng)(neng)及(ji)使(shi)用(yong)壽命上(shang)均存(cun)在(zai)較(jiao)大(da)差(cha)距。基于國(guo)(guo)內產業升(sheng)級與進口替代(dai)的(de)強烈需求(qiu)，攀(pan)鋼科研(yan)人員從(cong)材料設計出發，系統研(yan)究合(he)金(jin)成(cheng)分、冶煉(lian)工(gong)(gong)(gong)藝(yi)、加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)及(ji)熱(re)處理工(gong)(gong)(gong)藝(yi)等因素對Cr20Ni80電(dian)(dian)熱(re)合(he)金(jin)性(xing)能(neng)(neng)的(de)影(ying)響規律，深(shen)度(du)優化(hua)Cr20Ni80電(dian)(dian)熱(re)合(he)金(jin)成(cheng)分及(ji)全(quan)流(liu)程(cheng)生產工(gong)(gong)(gong)藝(yi)。經多輪次(ci)(ci)實(shi)驗(yan)室小錠型試(shi)驗(yan)驗(yan)證和(he)數(shu)值模擬驗(yan)證后，通過工(gong)(gong)(gong)業試(shi)制，成(cheng)功打通大(da)功率電(dian)(dian)爐用(yong)高(gao)性(xing)能(neng)(neng)Cr20Ni80電(dian)(dian)熱(re)合(he)金(jin)線材產品生產全(quan)流(liu)程(cheng)工(gong)(gong)(gong)藝(yi)，首次(ci)(ci)完成(cheng)噸級成(cheng)品試(shi)制，產品質量(liang)達標，綜合(he)性(xing)能(neng)(neng)達到(dao)國(guo)(guo)內領先水平。
