前不久，由攀鋼(gang)研制的大功率電爐用(yong)高(gao)性能Cr20Ni80電熱合(he)金(jin)線材(cai)產(chan)品(pin)試(shi)(shi)用(yong)周期超過一年，使用(yong)壽命高(gao)出國(guo)內同行業(ye)平(ping)(ping)均水(shui)平(ping)(ping)40%以上，其他綜合(he)指標(biao)也獲(huo)得試(shi)(shi)用(yong)客(ke)戶好評。經客(ke)戶論證，成功獲(huo)得可參與招標(biao)的合(he)格(ge)供貨(huo)商資格(ge)。

據悉(xi)，Cr20Ni80電(dian)熱(re)合金具有熔點高(gao)(gao)、電(dian)阻率高(gao)(gao)、電(dian)阻溫(wen)(wen)度(du)系數小、高(gao)(gao)中(zhong)低溫(wen)(wen)抗氧化性能好(hao)等(deng)特(te)(te)點，多用(yong)于(yu)生產電(dian)熱(re)元(yuan)(yuan)件、高(gao)(gao)中(zhong)溫(wen)(wen)電(dian)阻元(yuan)(yuan)件、應力測量元(yuan)(yuan)件和特(te)(te)殊元(yuan)(yuan)件等(deng)，是電(dian)氣領域重要的基礎材料。

我國是(shi)電(dian)(dian)熱(re)合(he)(he)金(jin)的(de)主(zhu)要消(xiao)耗國，國內(nei)電(dian)(dian)熱(re)合(he)(he)金(jin)生產企業(ye)(ye)(ye)(ye)以中小型民(min)營企業(ye)(ye)(ye)(ye)為主(zhu)。與(yu)進口產品(pin)(pin)相比，國產電(dian)(dian)熱(re)合(he)(he)金(jin)產品(pin)(pin)在質量、性(xing)(xing)能(neng)及(ji)使用壽命上均存在較大差距。基于國內(nei)產業(ye)(ye)(ye)(ye)升(sheng)級與(yu)進口替代的(de)強烈需求，攀鋼科研(yan)人員從材(cai)料(liao)設計出發，系統研(yan)究合(he)(he)金(jin)成(cheng)分(fen)、冶煉(lian)工(gong)(gong)(gong)藝、加工(gong)(gong)(gong)工(gong)(gong)(gong)藝及(ji)熱(re)處理工(gong)(gong)(gong)藝等(deng)因素對Cr20Ni80電(dian)(dian)熱(re)合(he)(he)金(jin)性(xing)(xing)能(neng)的(de)影響(xiang)規律，深(shen)度優(you)化Cr20Ni80電(dian)(dian)熱(re)合(he)(he)金(jin)成(cheng)分(fen)及(ji)全(quan)流程(cheng)生產工(gong)(gong)(gong)藝。經多輪次(ci)實驗(yan)(yan)(yan)室(shi)小錠型試(shi)驗(yan)(yan)(yan)驗(yan)(yan)(yan)證(zheng)和(he)數(shu)值模擬驗(yan)(yan)(yan)證(zheng)后，通過工(gong)(gong)(gong)業(ye)(ye)(ye)(ye)試(shi)制，成(cheng)功打(da)通大功率電(dian)(dian)爐(lu)用高性(xing)(xing)能(neng)Cr20Ni80電(dian)(dian)熱(re)合(he)(he)金(jin)線材(cai)產品(pin)(pin)生產全(quan)流程(cheng)工(gong)(gong)(gong)藝，首次(ci)完(wan)成(cheng)噸級成(cheng)品(pin)(pin)試(shi)制，產品(pin)(pin)質量達標，綜合(he)(he)性(xing)(xing)能(neng)達到(dao)國內(nei)領(ling)先水平。
