（1）使用合理的夾緊(jin)方法和固定(ding)裝置(zhi)

目的均勻(yun)加熱和(he)冷卻工件(jian)以(yi)減少不均勻(yun)的熱應力(li)(li)和(he)不均勻(yun)的組(zu)織應力(li)(li)以(yi)減少變形。夾(jia)緊方(fang)法(fa)可以(yi)改變。圓盤部件(jian)垂直于(yu)油面(mian)，軸(zhou)部件(jian)垂直安(an)裝。使用(yong)補償(chang)墊圈(quan)(quan)(quan)和(he)支撐墊圈(quan)(quan)(quan)。 ，花鍵(jian)孔部件(jian)可使用(yong)滲碳(tan)芯軸(zhou)，疊(die)加墊圈(quan)(quan)(quan)等。

（2）加工

當(dang)(dang)熱(re)(re)(re)處(chu)(chu)理(li)(li)是(shi)工(gong)(gong)(gong)件(jian)(jian)加(jia)(jia)(jia)工(gong)(gong)(gong)過(guo)程的(de)(de)(de)最后一步時，熱(re)(re)(re)處(chu)(chu)理(li)(li)變(bian)(bian)形(xing)(xing)(xing)的(de)(de)(de)允(yun)許(xu)值應滿足圖(tu)紙上指定(ding)的(de)(de)(de)工(gong)(gong)(gong)件(jian)(jian)尺寸(cun)，變(bian)(bian)形(xing)(xing)(xing)變(bian)(bian)量(liang)應根據前一加(jia)(jia)(jia)工(gong)(gong)(gong)的(de)(de)(de)尺寸(cun)確定(ding)。因(yin)此，根據工(gong)(gong)(gong)件(jian)(jian)的(de)(de)(de)變(bian)(bian)形(xing)(xing)(xing)，應在(zai)熱(re)(re)(re)處(chu)(chu)理(li)(li)之(zhi)前進行尺寸(cun)的(de)(de)(de)預校正，以使(shi)熱(re)(re)(re)處(chu)(chu)理(li)(li)變(bian)(bian)形(xing)(xing)(xing)在(zai)合(he)格范圍內。當(dang)(dang)熱(re)(re)(re)處(chu)(chu)理(li)(li)是(shi)中間過(guo)程時，應將(jiang)熱(re)(re)(re)處(chu)(chu)理(li)(li)前的(de)(de)(de)加(jia)(jia)(jia)工(gong)(gong)(gong)余(yu)量(liang)視為加(jia)(jia)(jia)工(gong)(gong)(gong)余(yu)量(liang)和熱(re)(re)(re)處(chu)(chu)理(li)(li)變(bian)(bian)形(xing)(xing)(xing)的(de)(de)(de)總和。通常，加(jia)(jia)(jia)工(gong)(gong)(gong)余(yu)量(liang)容易確定(ding)，并且(qie)由于(yu)(yu)許(xu)多影(ying)響因(yin)素而(er)使(shi)熱(re)(re)(re)處(chu)(chu)理(li)(li)更加(jia)(jia)(jia)復(fu)雜，因(yin)此留有足夠(gou)的(de)(de)(de)加(jia)(jia)(jia)工(gong)(gong)(gong)余(yu)量(liang)用(yong)于(yu)(yu)加(jia)(jia)(jia)工(gong)(gong)(gong)，其余(yu)的(de)(de)(de)可以用(yong)作熱(re)(re)(re)處(chu)(chu)理(li)(li)容許(xu)變(bian)(bian)形(xing)(xing)(xing)變(bian)(bian)量(liang)。熱(re)(re)(re)處(chu)(chu)理(li)(li)后的(de)(de)(de)加(jia)(jia)(jia)工(gong)(gong)(gong)后，根據工(gong)(gong)(gong)件(jian)(jian)的(de)(de)(de)變(bian)(bian)形(xing)(xing)(xing)規律(lv)，采用(yong)抗變(bian)(bian)形(xing)(xing)(xing)和收(shou)縮端(duan)預擴孔，以提高淬火后的(de)(de)(de)變(bian)(bian)形(xing)(xing)(xing)合(he)格率。

（3）使用(yong)適當的媒體

鋼熱處理廠家在(zai)確保相(xiang)(xiang)同的(de)硬度要求的(de)前提(ti)下，嘗試使用油(you)性(xing)(xing)介質(zhi)。實(shi)驗和(he)實(shi)踐證明，在(zai)沒有其(qi)他(ta)條件(jian)的(de)前提(ti)下，油(you)性(xing)(xing)介質(zhi)的(de)冷(leng)卻速(su)度較慢，而(er)水性(xing)(xing)介質(zhi)的(de)冷(leng)卻速(su)度則相(xiang)(xiang)對(dui)(dui)較快。而(er)且，與油(you)性(xing)(xing)介質(zhi)相(xiang)(xiang)比，水溫變化對(dui)(dui)水性(xing)(xing)介質(zhi)的(de)冷(leng)卻特性(xing)(xing)影響更大。在(zai)相(xiang)(xiang)同的(de)熱(re)處理條件(jian)下，與水性(xing)(xing)介質(zhi)相(xiang)(xiang)比，淬火后油(you)性(xing)(xing)介質(zhi)的(de)變形量相(xiang)(xiang)對(dui)(dui)較小(xiao)。

鋼熱處理廠家可以(yi)改善(shan)工件(jian)的(de)(de)機械性能，并提(ti)高工件(jian)的(de)(de)強度和(he)硬度，但不可避(bi)免地產生變(bian)形效果。現階段(duan)，我們(men)必須重視中國(guo)熱處(chu)理技(ji)(ji)術(shu)和(he)設備的(de)(de)改進，不斷(duan)學習國(guo)外先進技(ji)(ji)術(shu)，提(ti)高熱處(chu)理工件(jian)的(de)(de)質量和(he)合格(ge)率(lv)，為中國(guo)熱處(chu)理行(xing)業(ye)做(zuo)出貢獻。
