（1）使(shi)用合理的夾緊方法和固(gu)定裝置

目的(de)均勻加(jia)熱和冷卻工件(jian)(jian)以(yi)減(jian)少不均勻的(de)熱應(ying)力和不均勻的(de)組織應(ying)力以(yi)減(jian)少變形。夾緊方法可以(yi)改變。圓(yuan)盤(pan)部(bu)件(jian)(jian)垂直于油面，軸部(bu)件(jian)(jian)垂直安裝。使用補償墊(dian)(dian)圈和支(zhi)撐墊(dian)(dian)圈。 ，花鍵孔部(bu)件(jian)(jian)可使用滲碳(tan)芯軸，疊(die)加(jia)墊(dian)(dian)圈等。

（2）加工

當(dang)熱(re)(re)(re)(re)(re)處(chu)理(li)(li)(li)是工(gong)(gong)(gong)件(jian)加(jia)(jia)工(gong)(gong)(gong)過程(cheng)的(de)(de)(de)最后(hou)(hou)一(yi)步時(shi)，熱(re)(re)(re)(re)(re)處(chu)理(li)(li)(li)變(bian)(bian)形(xing)(xing)(xing)的(de)(de)(de)允(yun)許值應(ying)滿足圖紙上指(zhi)定(ding)的(de)(de)(de)工(gong)(gong)(gong)件(jian)尺(chi)寸(cun)，變(bian)(bian)形(xing)(xing)(xing)變(bian)(bian)量應(ying)根據(ju)前一(yi)加(jia)(jia)工(gong)(gong)(gong)的(de)(de)(de)尺(chi)寸(cun)確定(ding)。因(yin)此，根據(ju)工(gong)(gong)(gong)件(jian)的(de)(de)(de)變(bian)(bian)形(xing)(xing)(xing)，應(ying)在熱(re)(re)(re)(re)(re)處(chu)理(li)(li)(li)之前進行(xing)尺(chi)寸(cun)的(de)(de)(de)預校(xiao)正(zheng)，以使熱(re)(re)(re)(re)(re)處(chu)理(li)(li)(li)變(bian)(bian)形(xing)(xing)(xing)在合(he)(he)格(ge)范圍內(nei)。當(dang)熱(re)(re)(re)(re)(re)處(chu)理(li)(li)(li)是中間過程(cheng)時(shi)，應(ying)將熱(re)(re)(re)(re)(re)處(chu)理(li)(li)(li)前的(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)余量視為加(jia)(jia)工(gong)(gong)(gong)余量和熱(re)(re)(re)(re)(re)處(chu)理(li)(li)(li)變(bian)(bian)形(xing)(xing)(xing)的(de)(de)(de)總和。通(tong)常(chang)，加(jia)(jia)工(gong)(gong)(gong)余量容易確定(ding)，并且由于許多影響因(yin)素而使熱(re)(re)(re)(re)(re)處(chu)理(li)(li)(li)更加(jia)(jia)復雜，因(yin)此留有足夠(gou)的(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)余量用(yong)(yong)于加(jia)(jia)工(gong)(gong)(gong)，其余的(de)(de)(de)可以用(yong)(yong)作熱(re)(re)(re)(re)(re)處(chu)理(li)(li)(li)容許變(bian)(bian)形(xing)(xing)(xing)變(bian)(bian)量。熱(re)(re)(re)(re)(re)處(chu)理(li)(li)(li)后(hou)(hou)的(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)后(hou)(hou)，根據(ju)工(gong)(gong)(gong)件(jian)的(de)(de)(de)變(bian)(bian)形(xing)(xing)(xing)規律，采用(yong)(yong)抗變(bian)(bian)形(xing)(xing)(xing)和收縮端預擴孔，以提高淬火(huo)后(hou)(hou)的(de)(de)(de)變(bian)(bian)形(xing)(xing)(xing)合(he)(he)格(ge)率(lv)。

（3）使用適當的媒體

鋼熱處理廠家在(zai)確保相(xiang)同(tong)(tong)的(de)(de)硬(ying)度要求的(de)(de)前提下(xia)，嘗(chang)試使(shi)用油(you)性(xing)(xing)介(jie)質(zhi)(zhi)。實驗(yan)和實踐(jian)證明，在(zai)沒有(you)其他條(tiao)件(jian)的(de)(de)前提下(xia)，油(you)性(xing)(xing)介(jie)質(zhi)(zhi)的(de)(de)冷卻(que)(que)速度較慢，而(er)水性(xing)(xing)介(jie)質(zhi)(zhi)的(de)(de)冷卻(que)(que)速度則相(xiang)對較快。而(er)且(qie)，與(yu)油(you)性(xing)(xing)介(jie)質(zhi)(zhi)相(xiang)比(bi)，水溫變化對水性(xing)(xing)介(jie)質(zhi)(zhi)的(de)(de)冷卻(que)(que)特性(xing)(xing)影響更(geng)大。在(zai)相(xiang)同(tong)(tong)的(de)(de)熱處理條(tiao)件(jian)下(xia)，與(yu)水性(xing)(xing)介(jie)質(zhi)(zhi)相(xiang)比(bi)，淬火后油(you)性(xing)(xing)介(jie)質(zhi)(zhi)的(de)(de)變形量相(xiang)對較小。

鋼熱處理廠家可以改善工(gong)件(jian)(jian)(jian)的(de)機械性能(neng)，并提高工(gong)件(jian)(jian)(jian)的(de)強度(du)和(he)硬(ying)度(du)，但不可避免(mian)地產生變形效果(guo)。現階段，我們必須重視中國熱處(chu)(chu)(chu)理(li)技術(shu)和(he)設(she)備的(de)改進(jin)，不斷(duan)學習國外先進(jin)技術(shu)，提高熱處(chu)(chu)(chu)理(li)工(gong)件(jian)(jian)(jian)的(de)質量(liang)和(he)合格率，為中國熱處(chu)(chu)(chu)理(li)行業(ye)做出(chu)貢(gong)獻。
