前不(bu)久，由攀鋼研制(zhi)的(de)大功率電爐用(yong)(yong)高(gao)性(xing)能Cr20Ni80電熱(re)合金線(xian)材產品試(shi)用(yong)(yong)周期超(chao)過一年，使用(yong)(yong)壽(shou)命高(gao)出(chu)國(guo)內同(tong)行業平均水平40%以上，其他綜合指標(biao)也獲(huo)得試(shi)用(yong)(yong)客戶(hu)好評。經客戶(hu)論證，成功獲(huo)得可參與招標(biao)的(de)合格供貨(huo)商(shang)資(zi)格。

據悉，Cr20Ni80電(dian)熱合(he)金具有熔(rong)點(dian)高、電(dian)阻率高、電(dian)阻溫(wen)度系數小(xiao)、高中低溫(wen)抗氧化性能好等特點(dian)，多用于生(sheng)產(chan)電(dian)熱元(yuan)件、高中溫(wen)電(dian)阻元(yuan)件、應力(li)測量元(yuan)件和特殊元(yuan)件等，是電(dian)氣領域重要的基(ji)礎(chu)材料(liao)。

我國(guo)(guo)是電熱(re)合(he)(he)金(jin)的(de)(de)主(zhu)要(yao)消耗國(guo)(guo)，國(guo)(guo)內電熱(re)合(he)(he)金(jin)生(sheng)產(chan)(chan)(chan)企(qi)業以中小(xiao)型民營企(qi)業為主(zhu)。與進(jin)口產(chan)(chan)(chan)品(pin)(pin)相比，國(guo)(guo)產(chan)(chan)(chan)電熱(re)合(he)(he)金(jin)產(chan)(chan)(chan)品(pin)(pin)在質量、性(xing)能及使(shi)用(yong)壽命上均存在較大差距。基于國(guo)(guo)內產(chan)(chan)(chan)業升級(ji)與進(jin)口替代的(de)(de)強烈需求(qiu)，攀鋼科研人員(yuan)從(cong)材料設計出發，系統研究(jiu)合(he)(he)金(jin)成(cheng)(cheng)分、冶煉工(gong)(gong)藝、加工(gong)(gong)工(gong)(gong)藝及熱(re)處理工(gong)(gong)藝等因素(su)對Cr20Ni80電熱(re)合(he)(he)金(jin)性(xing)能的(de)(de)影響規律，深度優化Cr20Ni80電熱(re)合(he)(he)金(jin)成(cheng)(cheng)分及全流(liu)程生(sheng)產(chan)(chan)(chan)工(gong)(gong)藝。經多輪次(ci)實驗(yan)室(shi)小(xiao)錠型試驗(yan)驗(yan)證(zheng)和數值模擬驗(yan)證(zheng)后，通過工(gong)(gong)業試制，成(cheng)(cheng)功(gong)打通大功(gong)率(lv)電爐用(yong)高(gao)性(xing)能Cr20Ni80電熱(re)合(he)(he)金(jin)線材產(chan)(chan)(chan)品(pin)(pin)生(sheng)產(chan)(chan)(chan)全流(liu)程工(gong)(gong)藝，首次(ci)完成(cheng)(cheng)噸(dun)級(ji)成(cheng)(cheng)品(pin)(pin)試制，產(chan)(chan)(chan)品(pin)(pin)質量達標，綜合(he)(he)性(xing)能達到國(guo)(guo)內領先水平。
