（1）使用合理的夾(jia)緊方法和固定(ding)裝置

目的均(jun)勻加熱和冷卻工件(jian)以(yi)減少不均(jun)勻的熱應(ying)力和不均(jun)勻的組織應(ying)力以(yi)減少變形(xing)。夾緊方法可以(yi)改變。圓盤部件(jian)垂直(zhi)于油(you)面，軸部件(jian)垂直(zhi)安裝(zhuang)。使用補償墊圈(quan)和支撐墊圈(quan)。 ，花鍵孔部件(jian)可使用滲碳芯軸，疊(die)加墊圈(quan)等(deng)。

（2）加工

當(dang)(dang)熱(re)(re)(re)處(chu)理(li)是工(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)件加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)過(guo)程的(de)(de)最(zui)后一步時，熱(re)(re)(re)處(chu)理(li)變(bian)(bian)形(xing)(xing)(xing)的(de)(de)允(yun)許值應滿足圖紙上指定(ding)的(de)(de)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)件尺(chi)寸，變(bian)(bian)形(xing)(xing)(xing)變(bian)(bian)量應根(gen)據(ju)前(qian)一加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)的(de)(de)尺(chi)寸確(que)定(ding)。因(yin)此，根(gen)據(ju)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)件的(de)(de)變(bian)(bian)形(xing)(xing)(xing)，應在熱(re)(re)(re)處(chu)理(li)之(zhi)前(qian)進行(xing)尺(chi)寸的(de)(de)預(yu)校(xiao)正，以(yi)使(shi)熱(re)(re)(re)處(chu)理(li)變(bian)(bian)形(xing)(xing)(xing)在合(he)格(ge)范圍內。當(dang)(dang)熱(re)(re)(re)處(chu)理(li)是中間過(guo)程時，應將熱(re)(re)(re)處(chu)理(li)前(qian)的(de)(de)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)余(yu)量視(shi)為加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)余(yu)量和熱(re)(re)(re)處(chu)理(li)變(bian)(bian)形(xing)(xing)(xing)的(de)(de)總和。通常，加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)余(yu)量容易確(que)定(ding)，并且由(you)于(yu)許多影響因(yin)素(su)而使(shi)熱(re)(re)(re)處(chu)理(li)更加(jia)復雜，因(yin)此留有(you)足夠(gou)的(de)(de)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)余(yu)量用于(yu)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)，其余(yu)的(de)(de)可(ke)以(yi)用作熱(re)(re)(re)處(chu)理(li)容許變(bian)(bian)形(xing)(xing)(xing)變(bian)(bian)量。熱(re)(re)(re)處(chu)理(li)后的(de)(de)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)后，根(gen)據(ju)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)件的(de)(de)變(bian)(bian)形(xing)(xing)(xing)規律，采用抗變(bian)(bian)形(xing)(xing)(xing)和收(shou)縮端(duan)預(yu)擴孔，以(yi)提(ti)高淬火后的(de)(de)變(bian)(bian)形(xing)(xing)(xing)合(he)格(ge)率。

（3）使(shi)用(yong)適當的媒體

鋼熱處理廠家在確保(bao)相(xiang)同(tong)的硬(ying)度(du)(du)要求的前提下(xia)，嘗試使(shi)用油(you)性(xing)(xing)(xing)介(jie)(jie)質。實(shi)驗和實(shi)踐(jian)證明(ming)，在沒有其他條件(jian)的前提下(xia)，油(you)性(xing)(xing)(xing)介(jie)(jie)質的冷卻速(su)度(du)(du)較(jiao)慢，而水(shui)(shui)性(xing)(xing)(xing)介(jie)(jie)質的冷卻速(su)度(du)(du)則相(xiang)對較(jiao)快。而且，與油(you)性(xing)(xing)(xing)介(jie)(jie)質相(xiang)比(bi)，水(shui)(shui)溫(wen)變化(hua)對水(shui)(shui)性(xing)(xing)(xing)介(jie)(jie)質的冷卻特性(xing)(xing)(xing)影響更大。在相(xiang)同(tong)的熱(re)處理(li)條件(jian)下(xia)，與水(shui)(shui)性(xing)(xing)(xing)介(jie)(jie)質相(xiang)比(bi)，淬火后油(you)性(xing)(xing)(xing)介(jie)(jie)質的變形量相(xiang)對較(jiao)小。

鋼熱處理廠家可(ke)以改(gai)善工件的(de)(de)機械性能，并提高工件的(de)(de)強度和(he)硬度，但不可(ke)避(bi)免地產生變形效果。現階段，我們必(bi)須重視中國(guo)熱處(chu)理(li)(li)技(ji)(ji)術和(he)設(she)備的(de)(de)改(gai)進，不斷(duan)學(xue)習國(guo)外先(xian)進技(ji)(ji)術，提高熱處(chu)理(li)(li)工件的(de)(de)質量和(he)合格率(lv)，為中國(guo)熱處(chu)理(li)(li)行業做出貢獻。
