前不久，由(you)攀(pan)鋼(gang)研制的大功率電(dian)爐用高(gao)性能Cr20Ni80電(dian)熱合金線材產品試用周期超過一(yi)年，使用壽命高(gao)出國內同(tong)行業(ye)平(ping)均水平(ping)40%以上，其他綜合指(zhi)標也獲(huo)得試用客(ke)戶(hu)好評。經(jing)客(ke)戶(hu)論(lun)證，成功獲(huo)得可參與(yu)招標的合格供貨(huo)商資(zi)格。

據悉(xi)，Cr20Ni80電(dian)(dian)(dian)(dian)熱合金具(ju)有熔點(dian)高(gao)、電(dian)(dian)(dian)(dian)阻率高(gao)、電(dian)(dian)(dian)(dian)阻溫度系(xi)數(shu)小、高(gao)中低溫抗氧(yang)化性能(neng)好等特(te)點(dian)，多用(yong)于生產電(dian)(dian)(dian)(dian)熱元件(jian)、高(gao)中溫電(dian)(dian)(dian)(dian)阻元件(jian)、應力測量元件(jian)和(he)特(te)殊元件(jian)等，是(shi)電(dian)(dian)(dian)(dian)氣領域重(zhong)要的基礎材(cai)料(liao)。

我國(guo)是電(dian)熱(re)(re)(re)(re)合金(jin)的主(zhu)要(yao)消耗國(guo)，國(guo)內電(dian)熱(re)(re)(re)(re)合金(jin)生產(chan)(chan)(chan)企業以中小型(xing)民(min)營企業為主(zhu)。與(yu)進口產(chan)(chan)(chan)品(pin)相比，國(guo)產(chan)(chan)(chan)電(dian)熱(re)(re)(re)(re)合金(jin)產(chan)(chan)(chan)品(pin)在(zai)質(zhi)量、性能及(ji)使(shi)用壽(shou)命(ming)上均存在(zai)較(jiao)大差距。基于(yu)國(guo)內產(chan)(chan)(chan)業升級與(yu)進口替代的強烈(lie)需求，攀鋼科研人員(yuan)從材(cai)料設(she)計(ji)出發，系(xi)統研究合金(jin)成(cheng)分(fen)、冶煉工藝、加工工藝及(ji)熱(re)(re)(re)(re)處(chu)理工藝等因素對Cr20Ni80電(dian)熱(re)(re)(re)(re)合金(jin)性能的影(ying)響規律，深度優化Cr20Ni80電(dian)熱(re)(re)(re)(re)合金(jin)成(cheng)分(fen)及(ji)全流程生產(chan)(chan)(chan)工藝。經多輪次實驗(yan)室(shi)小錠(ding)型(xing)試(shi)(shi)驗(yan)驗(yan)證和數值模(mo)擬驗(yan)證后(hou)，通(tong)過工業試(shi)(shi)制(zhi)，成(cheng)功打(da)通(tong)大功率(lv)電(dian)爐用高性能Cr20Ni80電(dian)熱(re)(re)(re)(re)合金(jin)線材(cai)產(chan)(chan)(chan)品(pin)生產(chan)(chan)(chan)全流程工藝，首次完成(cheng)噸級成(cheng)品(pin)試(shi)(shi)制(zhi)，產(chan)(chan)(chan)品(pin)質(zhi)量達標，綜合性能達到國(guo)內領先(xian)水平。
