　　真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)熔煉(lian)爐(lu)(lu)(lu)采(cai)用耐(nai)熱(re)(re)鋼制造的(de)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)罐(guan)放(fang)入(ru)電(dian)(dian)阻爐(lu)(lu)(lu)中，根據(ju)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)熱(re)(re)處理工藝(yi)的(de)需要(yao)，配接適當的(de)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)系(xi)統，即成(cheng)(cheng)(cheng)為(wei)筒單(dan)的(de)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)熱(re)(re)處理爐(lu)(lu)(lu)。是由電(dian)(dian)阻爐(lu)(lu)(lu)，真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)罐(guan)硬和真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)泵真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)悶門(men)、真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)計(ji)等構成(cheng)(cheng)(cheng)的(de)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)系(xi)統。其熱(re)(re)源在(zai)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)的(de)外部(bu)，也就是電(dian)(dian)熱(re)(re)元件設置在(zai)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)罐(guan)的(de)外部(bu)，工件放(fang)在(zai)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)罐(guan)的(de)內部(bu)，靠間(jian)接加(jia)熱(re)(re)。 　　真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)熔煉(lian)爐(lu)(lu)(lu)有以下幾(ji)種(zhong)結構： 　　1.鐘罩式結構 　　這種(zhong)結構的(de)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)缺座落在(zai)爐(lu)(lu)(lu)底(di)上，整個爐(lu)(lu)(lu)底(di)和真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)罐(guan)可(ke)以借助(zhu)于電(dian)(dian)動(dong)或液壓傳動(dong)升(sheng)降(jiang)，以完成(cheng)(cheng)(cheng)裝出料操作(zuo)并(bing)能(neng)縮(suo)短冷卻(que)時(shi)間(jian)。也可(ke)以采(cai)取(qu)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)罐(guan)和爐(lu)(lu)(lu)底(di)固定(ding)不動(dong)，罩式爐(lu)(lu)(lu)體(ti)升(sheng)降(jiang)的(de)方(fang)法(fa)來完成(cheng)(cheng)(cheng)進出料操作(zuo)等，但(dan)是爐(lu)(lu)(lu)體(ti)升(sheng)降(jiang)較為(wei)復雜。采(cai)用哪一種(zhong)方(fang)法(fa)，要(yao)根據(ju)現場實際情況而(er)定(ding)。 　　2.雙真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)結構 　　這種(zhong)結構不僅真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)罐(guan)內部(bu)被(bei)抽成(cheng)(cheng)(cheng)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)，而(er)且真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)罐(guan)外部(bu)的(de)爐(lu)(lu)(lu)體(ti)部(bu)分(fen)也被(bei)抽成(cheng)(cheng)(cheng)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)。這樣，就可(ke)以減少真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)鑲承受的(de)壓力，避免真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)罐(guan)外壁(bi)氧化(hua)和變形，延(yan)長了真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)罐(guan)的(de)使用壽命。 　　在(zai)使用時(shi)還要(yao)注意，真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)罐(guan)是真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)甩帶爐(lu)(lu)(lu)的(de)關鍵性(xing)部(bu)件。由于真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)罐(guan)須在(zai)高(gao)(gao)溫(wen)和一個大氣壓的(de)外壓條(tiao)件下工作(zuo)，所以，真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)罐(guan)的(de)材料應具備(bei)良好的(de)熱(re)(re)穩定(ding)性(xing)和耐(nai)氧化(hua)性(xing)，間(jian)接性(xing)能(neng)要(yao)好，焊縫不易(yi)產生氣孔、開(kai)裂，保證(zheng)高(gao)(gao)溫(wen)氣密性(xing)。材料成(cheng)(cheng)(cheng)分(fen)中的(de)元素蒸氣壓要(yao)低，防止合金元素在(zai)高(gao)(gao)溫(wen)、高(gao)(gao)真(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)(kong)下揮發(fa)。
