前不久，由攀鋼研制的大(da)功率電爐用(yong)(yong)高性能Cr20Ni80電熱合金線(xian)材產品試用(yong)(yong)周期超過一(yi)年，使用(yong)(yong)壽命(ming)高出國內(nei)同行業平均水平40%以(yi)上，其他綜合指標也(ye)獲得(de)(de)試用(yong)(yong)客戶(hu)好評。經客戶(hu)論證，成功獲得(de)(de)可參(can)與招標的合格(ge)供貨商資格(ge)。

據悉，Cr20Ni80電(dian)熱合(he)金具有熔點(dian)(dian)高(gao)、電(dian)阻率(lv)高(gao)、電(dian)阻溫(wen)(wen)度系數小、高(gao)中低溫(wen)(wen)抗氧化性能好等(deng)特點(dian)(dian)，多用于生產(chan)電(dian)熱元(yuan)件、高(gao)中溫(wen)(wen)電(dian)阻元(yuan)件、應力測量元(yuan)件和特殊(shu)元(yuan)件等(deng)，是電(dian)氣領域重(zhong)要的基礎材料。

我國(guo)是電熱(re)合(he)金(jin)的主要消耗(hao)國(guo)，國(guo)內電熱(re)合(he)金(jin)生產(chan)(chan)(chan)企業以中(zhong)小型民營(ying)企業為主。與進(jin)口產(chan)(chan)(chan)品(pin)相比，國(guo)產(chan)(chan)(chan)電熱(re)合(he)金(jin)產(chan)(chan)(chan)品(pin)在質(zhi)量(liang)、性(xing)能及使用壽命(ming)上均(jun)存在較大差距。基(ji)于國(guo)內產(chan)(chan)(chan)業升級(ji)與進(jin)口替代(dai)的強烈需(xu)求，攀鋼科研人員從材料(liao)設計出發(fa)，系統研究合(he)金(jin)成(cheng)分、冶煉工(gong)(gong)(gong)藝(yi)、加工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)及熱(re)處理工(gong)(gong)(gong)藝(yi)等因素對(dui)Cr20Ni80電熱(re)合(he)金(jin)性(xing)能的影響(xiang)規律，深度優化(hua)Cr20Ni80電熱(re)合(he)金(jin)成(cheng)分及全(quan)(quan)流(liu)程生產(chan)(chan)(chan)工(gong)(gong)(gong)藝(yi)。經多輪次實(shi)驗(yan)(yan)(yan)室小錠(ding)型試驗(yan)(yan)(yan)驗(yan)(yan)(yan)證和數值模(mo)擬驗(yan)(yan)(yan)證后，通(tong)過工(gong)(gong)(gong)業試制(zhi)(zhi)，成(cheng)功(gong)打通(tong)大功(gong)率電爐用高性(xing)能Cr20Ni80電熱(re)合(he)金(jin)線材產(chan)(chan)(chan)品(pin)生產(chan)(chan)(chan)全(quan)(quan)流(liu)程工(gong)(gong)(gong)藝(yi)，首次完成(cheng)噸級(ji)成(cheng)品(pin)試制(zhi)(zhi)，產(chan)(chan)(chan)品(pin)質(zhi)量(liang)達(da)標(biao)，綜合(he)性(xing)能達(da)到國(guo)內領先水平(ping)。
