前(qian)不(bu)久，由攀鋼研制(zhi)的大功(gong)率電爐用(yong)高性能(neng)Cr20Ni80電熱合(he)金線材產品試用(yong)周期超(chao)過(guo)一年，使用(yong)壽命高出國內同行業(ye)平均(jun)水平40%以上，其他綜合(he)指標也獲(huo)得試用(yong)客(ke)戶好評(ping)。經客(ke)戶論證(zheng)，成功(gong)獲(huo)得可(ke)參與招標的合(he)格供貨商資格。

據(ju)悉(xi)，Cr20Ni80電(dian)(dian)熱合金具有熔點(dian)高、電(dian)(dian)阻率(lv)高、電(dian)(dian)阻溫度系數(shu)小、高中低(di)溫抗氧化性能(neng)好等特點(dian)，多(duo)用(yong)于生產(chan)電(dian)(dian)熱元件、高中溫電(dian)(dian)阻元件、應力測量元件和特殊元件等，是電(dian)(dian)氣領域(yu)重(zhong)要的基礎材料。

我(wo)國是電(dian)熱合(he)(he)金(jin)的(de)主(zhu)(zhu)要消(xiao)耗國，國內電(dian)熱合(he)(he)金(jin)生產(chan)企業(ye)(ye)以中小型民營企業(ye)(ye)為(wei)主(zhu)(zhu)。與進口(kou)產(chan)品(pin)(pin)相比，國產(chan)電(dian)熱合(he)(he)金(jin)產(chan)品(pin)(pin)在質量(liang)、性(xing)能(neng)(neng)及使用(yong)壽(shou)命(ming)上(shang)均存在較大差距。基于國內產(chan)業(ye)(ye)升級(ji)與進口(kou)替代的(de)強烈需求，攀鋼(gang)科研人員從(cong)材(cai)料設計出發，系統研究合(he)(he)金(jin)成(cheng)(cheng)分(fen)、冶煉(lian)工(gong)(gong)(gong)藝、加工(gong)(gong)(gong)工(gong)(gong)(gong)藝及熱處理工(gong)(gong)(gong)藝等因素對Cr20Ni80電(dian)熱合(he)(he)金(jin)性(xing)能(neng)(neng)的(de)影響規律，深度優化Cr20Ni80電(dian)熱合(he)(he)金(jin)成(cheng)(cheng)分(fen)及全流(liu)程(cheng)生產(chan)工(gong)(gong)(gong)藝。經多輪次(ci)實驗(yan)室小錠型試驗(yan)驗(yan)證和(he)數值模擬驗(yan)證后，通過工(gong)(gong)(gong)業(ye)(ye)試制，成(cheng)(cheng)功打通大功率電(dian)爐(lu)用(yong)高性(xing)能(neng)(neng)Cr20Ni80電(dian)熱合(he)(he)金(jin)線材(cai)產(chan)品(pin)(pin)生產(chan)全流(liu)程(cheng)工(gong)(gong)(gong)藝，首次(ci)完(wan)成(cheng)(cheng)噸級(ji)成(cheng)(cheng)品(pin)(pin)試制，產(chan)品(pin)(pin)質量(liang)達標，綜合(he)(he)性(xing)能(neng)(neng)達到國內領先(xian)水(shui)平。
