前(qian)不久，由攀鋼研制(zhi)的大(da)功(gong)(gong)率電(dian)(dian)爐用(yong)高(gao)(gao)性能(neng)Cr20Ni80電(dian)(dian)熱合金線(xian)材(cai)產(chan)品試用(yong)周(zhou)期超過一年，使(shi)用(yong)壽(shou)命高(gao)(gao)出(chu)國(guo)內同(tong)行業(ye)平均(jun)水平40%以上，其他綜合指標也(ye)獲得(de)(de)試用(yong)客(ke)戶好(hao)評。經(jing)客(ke)戶論證，成功(gong)(gong)獲得(de)(de)可(ke)參與招標的合格供貨(huo)商資(zi)格。

據悉，Cr20Ni80電(dian)熱合金具有熔點高(gao)(gao)、電(dian)阻率高(gao)(gao)、電(dian)阻溫度系數小(xiao)、高(gao)(gao)中(zhong)低溫抗氧(yang)化(hua)性(xing)能(neng)好等(deng)特點，多(duo)用于(yu)生產(chan)電(dian)熱元(yuan)件、高(gao)(gao)中(zhong)溫電(dian)阻元(yuan)件、應(ying)力測量(liang)元(yuan)件和特殊元(yuan)件等(deng)，是電(dian)氣領域(yu)重要(yao)的基礎材(cai)料(liao)。

我國(guo)是(shi)電(dian)(dian)(dian)(dian)熱(re)(re)合金(jin)(jin)(jin)的(de)主(zhu)要消(xiao)耗國(guo)，國(guo)內電(dian)(dian)(dian)(dian)熱(re)(re)合金(jin)(jin)(jin)生產(chan)(chan)企業(ye)以中(zhong)小型民營企業(ye)為主(zhu)。與(yu)(yu)進口(kou)產(chan)(chan)品(pin)相比(bi)，國(guo)產(chan)(chan)電(dian)(dian)(dian)(dian)熱(re)(re)合金(jin)(jin)(jin)產(chan)(chan)品(pin)在(zai)質(zhi)量(liang)、性能(neng)及(ji)使用壽命上(shang)均存在(zai)較大(da)差(cha)距。基于國(guo)內產(chan)(chan)業(ye)升級(ji)與(yu)(yu)進口(kou)替代(dai)的(de)強烈需求(qiu)，攀鋼科研人員從(cong)材料(liao)設計出發，系統研究合金(jin)(jin)(jin)成分、冶煉工(gong)(gong)(gong)藝(yi)、加工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)及(ji)熱(re)(re)處理工(gong)(gong)(gong)藝(yi)等因素對(dui)Cr20Ni80電(dian)(dian)(dian)(dian)熱(re)(re)合金(jin)(jin)(jin)性能(neng)的(de)影響(xiang)規(gui)律，深(shen)度(du)優化Cr20Ni80電(dian)(dian)(dian)(dian)熱(re)(re)合金(jin)(jin)(jin)成分及(ji)全流程生產(chan)(chan)工(gong)(gong)(gong)藝(yi)。經多輪次實驗(yan)室(shi)小錠型試驗(yan)驗(yan)證和數(shu)值(zhi)模擬驗(yan)證后，通(tong)(tong)過工(gong)(gong)(gong)業(ye)試制，成功打通(tong)(tong)大(da)功率電(dian)(dian)(dian)(dian)爐用高性能(neng)Cr20Ni80電(dian)(dian)(dian)(dian)熱(re)(re)合金(jin)(jin)(jin)線材產(chan)(chan)品(pin)生產(chan)(chan)全流程工(gong)(gong)(gong)藝(yi)，首次完成噸級(ji)成品(pin)試制，產(chan)(chan)品(pin)質(zhi)量(liang)達(da)標，綜合性能(neng)達(da)到國(guo)內領(ling)先水平。
