　　真(zhen)空(kong)(kong)燒(shao)結(jie)(jie)爐(lu)主要是用(yong)(yong)來處(chu)理(li)(li)(li)金屬(shu)材(cai)(cai)(cai)料(liao)(liao)(liao)的(de)(de)。很多(duo)金屬(shu)材(cai)(cai)(cai)料(liao)(liao)(liao)都(dou)是通過高(gao)溫(wen)(wen)(wen)(wen)來加(jia)工(gong)或作其他生產(chan)。那么，是否有(you)(you)某一(yi)類(lei)金屬(shu)材(cai)(cai)(cai)料(liao)(liao)(liao)不(bu)能在真(zhen)空(kong)(kong)爐(lu)中(zhong)熱處(chu)理(li)(li)(li)呢? 　　從(cong)理(li)(li)(li)論(lun)上(shang)講，金屬(shu)材(cai)(cai)(cai)料(liao)(liao)(liao)都(dou)可(ke)以在真(zhen)空(kong)(kong)燒(shao)結(jie)(jie)爐(lu)中(zhong)熱處(chu)理(li)(li)(li)。但(dan)因技術(shu)要求、加(jia)工(gong)成(cheng)本(ben)、工(gong)藝實現(xian)(xian)的(de)(de)難易程(cheng)度(du)等原因，下(xia)(xia)列(lie)材(cai)(cai)(cai)料(liao)(liao)(liao)(工(gong)件(jian))不(bu)宜在真(zhen)空(kong)(kong)爐(lu)中(zhong)熱處(chu)理(li)(li)(li)。 　　1.高(gao)溫(wen)(wen)(wen)(wen)對N元素敏(min)感，易形成(cheng)有(you)(you)害效(xiao)果(guo)的(de)(de)材(cai)(cai)(cai)料(liao)(liao)(liao)。真(zhen)空(kong)(kong)爐(lu)為(wei)防止合金元素高(gao)溫(wen)(wen)(wen)(wen)時揮發，通常在高(gao)溫(wen)(wen)(wen)(wen)下(xia)(xia)充高(gao)純氮氣保持分壓(ya)(ya)，冷卻時一(yi)般采用(yong)(yong)充氮冷卻。故該類(lei)材(cai)(cai)(cai)料(liao)(liao)(liao)不(bu)宜用(yong)(yong)真(zhen)空(kong)(kong)爐(lu)處(chu)理(li)(li)(li)。 　　2.碳(tan)(tan)素鋼。從(cong)成(cheng)本(ben)角度(du)考慮，碳(tan)(tan)鋼價格較低，成(cheng)品件(jian)價格較低，用(yong)(yong)真(zhen)空(kong)(kong)燒(shao)結(jie)(jie)爐(lu)處(chu)理(li)(li)(li)實屬(shu)浪費(fei)，除非高(gao)利潤(run)工(gong)件(jian)或者工(gong)件(jian)已(yi)經(jing)沒有(you)(you)加(jia)工(gong)余量，對表面(mian)質(zhi)量要求苛(ke)刻時的(de)(de)權宜之計。 　　3.某些使用(yong)(yong)特殊工(gong)藝的(de)(de)材(cai)(cai)(cai)料(liao)(liao)(liao)(工(gong)件(jian))。比如(ru)為(wei)獲(huo)取(qu)好的(de)(de)機械性能，有(you)(you)些工(gong)件(jian)要求獲(huo)得貝氏體，一(yi)般用(yong)(yong)等溫(wen)(wen)(wen)(wen)淬火(huo)來實現(xian)(xian)，真(zhen)空(kong)(kong)燒(shao)結(jie)(jie)爐(lu)很難實現(xian)(xian);再如(ru)T10鋼，要求高(gao)硬度(du)、低變形，一(yi)般用(yong)(yong)水(shui)淬油冷工(gong)藝實現(xian)(xian)，真(zhen)空(kong)(kong)爐(lu)雖然可(ke)以用(yong)(yong)高(gao)壓(ya)(ya)氣淬獲(huo)得高(gao)硬度(du)，但(dan)因在Ms點以下(xia)(xia)溫(wen)(wen)(wen)(wen)度(du)冷速(su)較快，變形較大。 　　好了(le)，總結(jie)(jie)的(de)(de)以上(shang)三種(zhong)材(cai)(cai)(cai)料(liao)(liao)(liao)就是不(bu)宜在真(zhen)空(kong)(kong)燒(shao)結(jie)(jie)爐(lu)中(zhong)處(chu)理(li)(li)(li)的(de)(de)金屬(shu)材(cai)(cai)(cai)料(liao)(liao)(liao)了(le)。
