前(qian)不久,由攀鋼研制的(de)大(da)功率(lv)電(dian)爐(lu)用(yong)高性(xing)能Cr20Ni80電(dian)熱合(he)金線材產品試用(yong)周期超過一年,使(shi)用(yong)壽(shou)命高出國內同行業平均水(shui)平40%以上,其(qi)他綜合(he)指標也獲(huo)得(de)試用(yong)客戶(hu)(hu)好評。經客戶(hu)(hu)論證,成功獲(huo)得(de)可參與招標的(de)合(he)格(ge)(ge)供貨商資格(ge)(ge)。


據(ju)悉,Cr20Ni80電(dian)熱合金具有熔點(dian)高(gao)、電(dian)阻率高(gao)、電(dian)阻溫(wen)度系數小(xiao)、高(gao)中低溫(wen)抗(kang)氧(yang)化性能好等(deng)特(te)點(dian),多用于(yu)生產電(dian)熱元(yuan)件(jian)(jian)、高(gao)中溫(wen)電(dian)阻元(yuan)件(jian)(jian)、應力測(ce)量元(yuan)件(jian)(jian)和特(te)殊元(yuan)件(jian)(jian)等(deng),是電(dian)氣領域重(zhong)要(yao)的基礎材料。


我國(guo)(guo)是電(dian)熱合(he)金的主要(yao)消耗(hao)國(guo)(guo),國(guo)(guo)內(nei)(nei)電(dian)熱合(he)金生產(chan)(chan)(chan)企業(ye)以中小型(xing)民營企業(ye)為主。與(yu)進(jin)口產(chan)(chan)(chan)品(pin)(pin)(pin)相(xiang)比,國(guo)(guo)產(chan)(chan)(chan)電(dian)熱合(he)金產(chan)(chan)(chan)品(pin)(pin)(pin)在(zai)質量、性能(neng)(neng)(neng)及(ji)使用(yong)壽命上均存在(zai)較大(da)差距。基于(yu)國(guo)(guo)內(nei)(nei)產(chan)(chan)(chan)業(ye)升級(ji)與(yu)進(jin)口替代的強(qiang)烈需求,攀鋼科研(yan)人(ren)員從材料設計出發,系統研(yan)究合(he)金成(cheng)(cheng)分、冶煉工藝(yi)、加工工藝(yi)及(ji)熱處理(li)工藝(yi)等因(yin)素對Cr20Ni80電(dian)熱合(he)金性能(neng)(neng)(neng)的影響規律,深(shen)度(du)優(you)化Cr20Ni80電(dian)熱合(he)金成(cheng)(cheng)分及(ji)全流(liu)(liu)程生產(chan)(chan)(chan)工藝(yi)。經多(duo)輪次實(shi)驗室小錠型(xing)試(shi)驗驗證和數值(zhi)模擬驗證后(hou),通過工業(ye)試(shi)制,成(cheng)(cheng)功打通大(da)功率電(dian)爐用(yong)高(gao)性能(neng)(neng)(neng)Cr20Ni80電(dian)熱合(he)金線材產(chan)(chan)(chan)品(pin)(pin)(pin)生產(chan)(chan)(chan)全流(liu)(liu)程工藝(yi),首次完(wan)成(cheng)(cheng)噸(dun)級(ji)成(cheng)(cheng)品(pin)(pin)(pin)試(shi)制,產(chan)(chan)(chan)品(pin)(pin)(pin)質量達標,綜合(he)性能(neng)(neng)(neng)達到(dao)國(guo)(guo)內(nei)(nei)領(ling)先水平。
