（1）使用合理的夾緊方法和(he)固(gu)定裝置

目(mu)的(de)均(jun)勻(yun)(yun)加熱和冷(leng)卻工件(jian)以(yi)減少不(bu)均(jun)勻(yun)(yun)的(de)熱應力和不(bu)均(jun)勻(yun)(yun)的(de)組織應力以(yi)減少變(bian)形。夾緊方法可(ke)以(yi)改變(bian)。圓(yuan)盤部件(jian)垂(chui)直(zhi)于油(you)面，軸(zhou)部件(jian)垂(chui)直(zhi)安裝。使(shi)用(yong)補(bu)償墊圈和支撐(cheng)墊圈。 ，花鍵孔(kong)部件(jian)可(ke)使(shi)用(yong)滲碳(tan)芯軸(zhou)，疊(die)加墊圈等(deng)。

（2）加工

當熱(re)處(chu)(chu)理(li)(li)是(shi)工(gong)(gong)(gong)(gong)件(jian)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)過程的(de)(de)(de)(de)最后(hou)一(yi)步時，熱(re)處(chu)(chu)理(li)(li)變(bian)(bian)(bian)(bian)形的(de)(de)(de)(de)允許值(zhi)應滿足(zu)圖紙上指定的(de)(de)(de)(de)工(gong)(gong)(gong)(gong)件(jian)尺寸，變(bian)(bian)(bian)(bian)形變(bian)(bian)(bian)(bian)量應根(gen)據前一(yi)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)的(de)(de)(de)(de)尺寸確定。因(yin)此(ci)，根(gen)據工(gong)(gong)(gong)(gong)件(jian)的(de)(de)(de)(de)變(bian)(bian)(bian)(bian)形，應在熱(re)處(chu)(chu)理(li)(li)之前進行尺寸的(de)(de)(de)(de)預校正，以使熱(re)處(chu)(chu)理(li)(li)變(bian)(bian)(bian)(bian)形在合格范圍內。當熱(re)處(chu)(chu)理(li)(li)是(shi)中間過程時，應將熱(re)處(chu)(chu)理(li)(li)前的(de)(de)(de)(de)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)余量視為加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)余量和(he)熱(re)處(chu)(chu)理(li)(li)變(bian)(bian)(bian)(bian)形的(de)(de)(de)(de)總和(he)。通常(chang)，加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)余量容易確定，并且由于(yu)(yu)許多影響因(yin)素而使熱(re)處(chu)(chu)理(li)(li)更(geng)加(jia)(jia)(jia)復雜，因(yin)此(ci)留(liu)有(you)足(zu)夠(gou)的(de)(de)(de)(de)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)余量用(yong)(yong)(yong)于(yu)(yu)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)，其余的(de)(de)(de)(de)可以用(yong)(yong)(yong)作熱(re)處(chu)(chu)理(li)(li)容許變(bian)(bian)(bian)(bian)形變(bian)(bian)(bian)(bian)量。熱(re)處(chu)(chu)理(li)(li)后(hou)的(de)(de)(de)(de)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)后(hou)，根(gen)據工(gong)(gong)(gong)(gong)件(jian)的(de)(de)(de)(de)變(bian)(bian)(bian)(bian)形規律，采(cai)用(yong)(yong)(yong)抗(kang)變(bian)(bian)(bian)(bian)形和(he)收縮端預擴孔(kong)，以提高淬火后(hou)的(de)(de)(de)(de)變(bian)(bian)(bian)(bian)形合格率。

（3）使用適當的媒體

鋼熱處理廠家在確保相(xiang)(xiang)同的(de)(de)(de)硬度要(yao)求(qiu)的(de)(de)(de)前(qian)提下，嘗試使用油(you)性(xing)(xing)介質。實驗(yan)和實踐(jian)證明(ming)，在沒有其(qi)他(ta)條(tiao)件的(de)(de)(de)前(qian)提下，油(you)性(xing)(xing)介質的(de)(de)(de)冷卻(que)速度較慢，而水性(xing)(xing)介質的(de)(de)(de)冷卻(que)速度則相(xiang)(xiang)對較快。而且，與油(you)性(xing)(xing)介質相(xiang)(xiang)比(bi)，水溫變(bian)化對水性(xing)(xing)介質的(de)(de)(de)冷卻(que)特性(xing)(xing)影響(xiang)更(geng)大(da)。在相(xiang)(xiang)同的(de)(de)(de)熱(re)處理(li)條(tiao)件下，與水性(xing)(xing)介質相(xiang)(xiang)比(bi)，淬火后油(you)性(xing)(xing)介質的(de)(de)(de)變(bian)形量相(xiang)(xiang)對較小。

鋼熱處理廠家可以改(gai)(gai)善(shan)工(gong)件(jian)(jian)的機(ji)械性能(neng)，并提(ti)高工(gong)件(jian)(jian)的強(qiang)度和(he)硬度，但不可避(bi)免地產生變形(xing)效果。現階段，我們必須(xu)重(zhong)視(shi)中(zhong)國(guo)(guo)熱(re)處(chu)(chu)(chu)理技(ji)術和(he)設備的改(gai)(gai)進，不斷學習國(guo)(guo)外先進技(ji)術，提(ti)高熱(re)處(chu)(chu)(chu)理工(gong)件(jian)(jian)的質(zhi)量和(he)合格率，為(wei)中(zhong)國(guo)(guo)熱(re)處(chu)(chu)(chu)理行業做(zuo)出貢(gong)獻(xian)。
