（1）使用合理的夾緊方法和固定裝置

目的均勻加熱和冷(leng)卻工(gong)件(jian)(jian)以減少不均勻的熱應(ying)力和不均勻的組(zu)織應(ying)力以減少變形(xing)。夾緊方法(fa)可以改變。圓盤部(bu)件(jian)(jian)垂直于(yu)油面，軸(zhou)部(bu)件(jian)(jian)垂直安裝(zhuang)。使用補償(chang)墊圈和支撐墊圈。 ，花鍵(jian)孔部(bu)件(jian)(jian)可使用滲(shen)碳芯軸(zhou)，疊加墊圈等。

（2）加工

當熱(re)(re)(re)(re)(re)處(chu)(chu)理(li)(li)(li)是(shi)工(gong)(gong)(gong)件(jian)加(jia)工(gong)(gong)(gong)過程(cheng)的(de)(de)(de)最后(hou)一步時，熱(re)(re)(re)(re)(re)處(chu)(chu)理(li)(li)(li)變(bian)(bian)(bian)形的(de)(de)(de)允許(xu)(xu)值(zhi)應滿(man)足圖(tu)紙上指定的(de)(de)(de)工(gong)(gong)(gong)件(jian)尺寸，變(bian)(bian)(bian)形變(bian)(bian)(bian)量(liang)應根據前一加(jia)工(gong)(gong)(gong)的(de)(de)(de)尺寸確(que)定。因(yin)此，根據工(gong)(gong)(gong)件(jian)的(de)(de)(de)變(bian)(bian)(bian)形，應在熱(re)(re)(re)(re)(re)處(chu)(chu)理(li)(li)(li)之前進行尺寸的(de)(de)(de)預校正，以(yi)使熱(re)(re)(re)(re)(re)處(chu)(chu)理(li)(li)(li)變(bian)(bian)(bian)形在合(he)格范圍內(nei)。當熱(re)(re)(re)(re)(re)處(chu)(chu)理(li)(li)(li)是(shi)中間過程(cheng)時，應將熱(re)(re)(re)(re)(re)處(chu)(chu)理(li)(li)(li)前的(de)(de)(de)加(jia)工(gong)(gong)(gong)余量(liang)視為加(jia)工(gong)(gong)(gong)余量(liang)和熱(re)(re)(re)(re)(re)處(chu)(chu)理(li)(li)(li)變(bian)(bian)(bian)形的(de)(de)(de)總和。通常(chang)，加(jia)工(gong)(gong)(gong)余量(liang)容易確(que)定，并且由于(yu)許(xu)(xu)多影(ying)響因(yin)素而使熱(re)(re)(re)(re)(re)處(chu)(chu)理(li)(li)(li)更加(jia)復(fu)雜，因(yin)此留有足夠(gou)的(de)(de)(de)加(jia)工(gong)(gong)(gong)余量(liang)用于(yu)加(jia)工(gong)(gong)(gong)，其余的(de)(de)(de)可以(yi)用作熱(re)(re)(re)(re)(re)處(chu)(chu)理(li)(li)(li)容許(xu)(xu)變(bian)(bian)(bian)形變(bian)(bian)(bian)量(liang)。熱(re)(re)(re)(re)(re)處(chu)(chu)理(li)(li)(li)后(hou)的(de)(de)(de)加(jia)工(gong)(gong)(gong)后(hou)，根據工(gong)(gong)(gong)件(jian)的(de)(de)(de)變(bian)(bian)(bian)形規(gui)律，采(cai)用抗(kang)變(bian)(bian)(bian)形和收縮端(duan)預擴(kuo)孔，以(yi)提高淬(cui)火后(hou)的(de)(de)(de)變(bian)(bian)(bian)形合(he)格率。

（3）使用(yong)適當的(de)媒(mei)體

鋼熱處理廠家在確保相(xiang)同的(de)(de)硬度(du)要求的(de)(de)前(qian)提(ti)(ti)下(xia)(xia)，嘗(chang)試使用油(you)性(xing)(xing)(xing)(xing)介質(zhi)(zhi)。實驗和實踐證明(ming)，在沒有(you)其他條件(jian)(jian)的(de)(de)前(qian)提(ti)(ti)下(xia)(xia)，油(you)性(xing)(xing)(xing)(xing)介質(zhi)(zhi)的(de)(de)冷卻速(su)度(du)較慢，而(er)水(shui)性(xing)(xing)(xing)(xing)介質(zhi)(zhi)的(de)(de)冷卻速(su)度(du)則相(xiang)對(dui)較快。而(er)且，與油(you)性(xing)(xing)(xing)(xing)介質(zhi)(zhi)相(xiang)比，水(shui)溫變化對(dui)水(shui)性(xing)(xing)(xing)(xing)介質(zhi)(zhi)的(de)(de)冷卻特性(xing)(xing)(xing)(xing)影響更(geng)大。在相(xiang)同的(de)(de)熱(re)處理(li)條件(jian)(jian)下(xia)(xia)，與水(shui)性(xing)(xing)(xing)(xing)介質(zhi)(zhi)相(xiang)比，淬火后油(you)性(xing)(xing)(xing)(xing)介質(zhi)(zhi)的(de)(de)變形量相(xiang)對(dui)較小。

鋼熱處理廠家可以改善工件(jian)的(de)機械(xie)性能，并(bing)提高(gao)(gao)工件(jian)的(de)強度和硬度，但(dan)不可避免地產生(sheng)變形效果。現階(jie)段，我們(men)必須重視中國(guo)熱處理(li)(li)技(ji)術(shu)和設備的(de)改進(jin)(jin)，不斷學習國(guo)外先進(jin)(jin)技(ji)術(shu)，提高(gao)(gao)熱處理(li)(li)工件(jian)的(de)質量和合格(ge)率，為中國(guo)熱處理(li)(li)行業(ye)做(zuo)出貢(gong)獻。
