前不久，由攀鋼研制的(de)大功率電爐用(yong)高性能Cr20Ni80電熱合(he)金(jin)線材產品試用(yong)周期超(chao)過一年，使用(yong)壽命高出(chu)國(guo)內同行(xing)業平均水平40%以上，其他綜合(he)指標也獲得試用(yong)客戶好評。經客戶論證(zheng)，成功獲得可參與招標的(de)合(he)格供貨商資格。

據悉(xi)，Cr20Ni80電(dian)(dian)熱合金具有(you)熔點高(gao)、電(dian)(dian)阻(zu)(zu)率高(gao)、電(dian)(dian)阻(zu)(zu)溫(wen)度系數小、高(gao)中低溫(wen)抗氧化性(xing)能好等特點，多用于(yu)生產電(dian)(dian)熱元件、高(gao)中溫(wen)電(dian)(dian)阻(zu)(zu)元件、應力測(ce)量元件和特殊元件等，是電(dian)(dian)氣領域重(zhong)要的(de)基(ji)礎(chu)材料。

我國(guo)是電熱(re)(re)(re)合(he)(he)金(jin)的主(zhu)(zhu)要消(xiao)耗國(guo)，國(guo)內(nei)電熱(re)(re)(re)合(he)(he)金(jin)生(sheng)產企(qi)業(ye)以中(zhong)小型民營企(qi)業(ye)為(wei)主(zhu)(zhu)。與進口(kou)產品(pin)(pin)相比，國(guo)產電熱(re)(re)(re)合(he)(he)金(jin)產品(pin)(pin)在(zai)(zai)質量、性能(neng)及(ji)使用(yong)壽(shou)命上均(jun)存在(zai)(zai)較大差距。基于(yu)國(guo)內(nei)產業(ye)升(sheng)級與進口(kou)替(ti)代的強烈需求，攀鋼(gang)科研(yan)人(ren)員從材(cai)料設計出發，系統研(yan)究(jiu)合(he)(he)金(jin)成(cheng)分(fen)、冶煉(lian)工(gong)(gong)(gong)藝(yi)(yi)、加工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)(yi)及(ji)熱(re)(re)(re)處理工(gong)(gong)(gong)藝(yi)(yi)等(deng)因素對(dui)Cr20Ni80電熱(re)(re)(re)合(he)(he)金(jin)性能(neng)的影響(xiang)規(gui)律，深度(du)優化(hua)Cr20Ni80電熱(re)(re)(re)合(he)(he)金(jin)成(cheng)分(fen)及(ji)全流(liu)程生(sheng)產工(gong)(gong)(gong)藝(yi)(yi)。經多輪次實驗(yan)室(shi)小錠型試(shi)驗(yan)驗(yan)證和數值模擬驗(yan)證后，通過工(gong)(gong)(gong)業(ye)試(shi)制(zhi)，成(cheng)功(gong)打通大功(gong)率電爐用(yong)高性能(neng)Cr20Ni80電熱(re)(re)(re)合(he)(he)金(jin)線材(cai)產品(pin)(pin)生(sheng)產全流(liu)程工(gong)(gong)(gong)藝(yi)(yi)，首次完成(cheng)噸級成(cheng)品(pin)(pin)試(shi)制(zhi)，產品(pin)(pin)質量達(da)標，綜(zong)合(he)(he)性能(neng)達(da)到國(guo)內(nei)領(ling)先水(shui)平。
