前不久(jiu)，由(you)攀鋼研制的大功率電爐用高性能(neng)Cr20Ni80電熱合金線材產品試(shi)用周期(qi)超過(guo)一年，使用壽命高出國內同行業平(ping)均(jun)水平(ping)40%以上，其(qi)他綜(zong)合指標也獲(huo)得試(shi)用客戶(hu)好評。經客戶(hu)論證，成功獲(huo)得可參(can)與(yu)招標的合格供貨(huo)商資(zi)格。

據悉，Cr20Ni80電(dian)(dian)(dian)熱(re)合金具有熔點(dian)(dian)高、電(dian)(dian)(dian)阻(zu)率(lv)高、電(dian)(dian)(dian)阻(zu)溫(wen)度系數小、高中低(di)溫(wen)抗氧化性(xing)能好等特點(dian)(dian)，多用于生產(chan)電(dian)(dian)(dian)熱(re)元(yuan)件(jian)(jian)、高中溫(wen)電(dian)(dian)(dian)阻(zu)元(yuan)件(jian)(jian)、應力測量(liang)元(yuan)件(jian)(jian)和特殊元(yuan)件(jian)(jian)等，是電(dian)(dian)(dian)氣領域重要的(de)基礎材料。

我國(guo)(guo)是電熱合(he)金(jin)的主(zhu)要消耗國(guo)(guo)，國(guo)(guo)內(nei)(nei)電熱合(he)金(jin)生產(chan)(chan)(chan)(chan)企業(ye)(ye)以中小(xiao)型民(min)營企業(ye)(ye)為(wei)主(zhu)。與進口(kou)產(chan)(chan)(chan)(chan)品(pin)(pin)相比，國(guo)(guo)產(chan)(chan)(chan)(chan)電熱合(he)金(jin)產(chan)(chan)(chan)(chan)品(pin)(pin)在(zai)質(zhi)量、性能(neng)(neng)(neng)及(ji)(ji)使用(yong)壽命(ming)上均存在(zai)較大差(cha)距。基于國(guo)(guo)內(nei)(nei)產(chan)(chan)(chan)(chan)業(ye)(ye)升級(ji)與進口(kou)替代(dai)的強烈(lie)需(xu)求，攀鋼科研人員從材料設計出發，系(xi)統研究合(he)金(jin)成分、冶煉工(gong)(gong)藝、加(jia)工(gong)(gong)工(gong)(gong)藝及(ji)(ji)熱處理工(gong)(gong)藝等(deng)因素(su)對Cr20Ni80電熱合(he)金(jin)性能(neng)(neng)(neng)的影響規律，深度優(you)化Cr20Ni80電熱合(he)金(jin)成分及(ji)(ji)全流程生產(chan)(chan)(chan)(chan)工(gong)(gong)藝。經多輪次實驗室小(xiao)錠型試(shi)驗驗證和數(shu)值模擬驗證后，通過(guo)工(gong)(gong)業(ye)(ye)試(shi)制(zhi)(zhi)，成功打通大功率電爐用(yong)高性能(neng)(neng)(neng)Cr20Ni80電熱合(he)金(jin)線(xian)材產(chan)(chan)(chan)(chan)品(pin)(pin)生產(chan)(chan)(chan)(chan)全流程工(gong)(gong)藝，首(shou)次完成噸級(ji)成品(pin)(pin)試(shi)制(zhi)(zhi)，產(chan)(chan)(chan)(chan)品(pin)(pin)質(zhi)量達標，綜(zong)合(he)性能(neng)(neng)(neng)達到國(guo)(guo)內(nei)(nei)領先水平。
