（1）使用合理的夾緊方法(fa)和(he)固定裝置

目(mu)的均(jun)勻(yun)加熱和冷卻工(gong)件(jian)以減(jian)(jian)少不(bu)均(jun)勻(yun)的熱應(ying)力和不(bu)均(jun)勻(yun)的組織應(ying)力以減(jian)(jian)少變(bian)形。夾(jia)緊方法可(ke)以改變(bian)。圓盤(pan)部(bu)件(jian)垂(chui)直于油(you)面(mian)，軸部(bu)件(jian)垂(chui)直安裝。使用補償墊圈和支撐墊圈。 ，花鍵孔部(bu)件(jian)可(ke)使用滲碳芯軸，疊加墊圈等。

（2）加工

當熱(re)處(chu)(chu)(chu)(chu)理是工(gong)(gong)(gong)件(jian)加(jia)工(gong)(gong)(gong)過程的(de)(de)最后(hou)一步時，熱(re)處(chu)(chu)(chu)(chu)理變(bian)(bian)(bian)形(xing)(xing)的(de)(de)允許值應滿(man)足圖(tu)紙上(shang)指定的(de)(de)工(gong)(gong)(gong)件(jian)尺寸(cun)(cun)，變(bian)(bian)(bian)形(xing)(xing)變(bian)(bian)(bian)量應根(gen)據(ju)前一加(jia)工(gong)(gong)(gong)的(de)(de)尺寸(cun)(cun)確定。因(yin)(yin)此，根(gen)據(ju)工(gong)(gong)(gong)件(jian)的(de)(de)變(bian)(bian)(bian)形(xing)(xing)，應在熱(re)處(chu)(chu)(chu)(chu)理之前進行尺寸(cun)(cun)的(de)(de)預校正，以使熱(re)處(chu)(chu)(chu)(chu)理變(bian)(bian)(bian)形(xing)(xing)在合(he)格范圍內(nei)。當熱(re)處(chu)(chu)(chu)(chu)理是中(zhong)間(jian)過程時，應將熱(re)處(chu)(chu)(chu)(chu)理前的(de)(de)加(jia)工(gong)(gong)(gong)余(yu)量視為加(jia)工(gong)(gong)(gong)余(yu)量和(he)熱(re)處(chu)(chu)(chu)(chu)理變(bian)(bian)(bian)形(xing)(xing)的(de)(de)總和(he)。通常，加(jia)工(gong)(gong)(gong)余(yu)量容易(yi)確定，并且(qie)由(you)于許多影響因(yin)(yin)素而(er)使熱(re)處(chu)(chu)(chu)(chu)理更(geng)加(jia)復雜，因(yin)(yin)此留有足夠(gou)的(de)(de)加(jia)工(gong)(gong)(gong)余(yu)量用(yong)(yong)于加(jia)工(gong)(gong)(gong)，其余(yu)的(de)(de)可以用(yong)(yong)作熱(re)處(chu)(chu)(chu)(chu)理容許變(bian)(bian)(bian)形(xing)(xing)變(bian)(bian)(bian)量。熱(re)處(chu)(chu)(chu)(chu)理后(hou)的(de)(de)加(jia)工(gong)(gong)(gong)后(hou)，根(gen)據(ju)工(gong)(gong)(gong)件(jian)的(de)(de)變(bian)(bian)(bian)形(xing)(xing)規律，采用(yong)(yong)抗變(bian)(bian)(bian)形(xing)(xing)和(he)收縮(suo)端(duan)預擴孔，以提(ti)高淬(cui)火(huo)后(hou)的(de)(de)變(bian)(bian)(bian)形(xing)(xing)合(he)格率。

（3）使用適(shi)當的媒體(ti)

鋼熱處理廠家在確保相(xiang)(xiang)(xiang)同的(de)硬度要求的(de)前提(ti)下(xia)，嘗試使用油(you)(you)性(xing)(xing)介(jie)質(zhi)(zhi)。實驗和實踐證明，在沒有其他(ta)條件(jian)(jian)的(de)前提(ti)下(xia)，油(you)(you)性(xing)(xing)介(jie)質(zhi)(zhi)的(de)冷卻速(su)度較(jiao)慢，而水性(xing)(xing)介(jie)質(zhi)(zhi)的(de)冷卻速(su)度則(ze)相(xiang)(xiang)(xiang)對較(jiao)快。而且，與油(you)(you)性(xing)(xing)介(jie)質(zhi)(zhi)相(xiang)(xiang)(xiang)比，水溫變化(hua)對水性(xing)(xing)介(jie)質(zhi)(zhi)的(de)冷卻特性(xing)(xing)影(ying)響更大。在相(xiang)(xiang)(xiang)同的(de)熱處理條件(jian)(jian)下(xia)，與水性(xing)(xing)介(jie)質(zhi)(zhi)相(xiang)(xiang)(xiang)比，淬火后(hou)油(you)(you)性(xing)(xing)介(jie)質(zhi)(zhi)的(de)變形量(liang)相(xiang)(xiang)(xiang)對較(jiao)小。

鋼熱處理廠家可(ke)以改(gai)善工件(jian)的(de)機械性能，并(bing)提(ti)高工件(jian)的(de)強(qiang)度(du)和硬度(du)，但不(bu)可(ke)避免地產(chan)生變形效果。現階段，我(wo)們必(bi)須重視中國熱(re)處理技術和設備的(de)改(gai)進(jin)，不(bu)斷學習國外先(xian)進(jin)技術，提(ti)高熱(re)處理工件(jian)的(de)質(zhi)量和合(he)格(ge)率，為中國熱(re)處理行業做出貢獻。
