（1）使用合理的夾緊方法(fa)和固(gu)定裝置

目的均勻(yun)(yun)加熱和(he)(he)冷卻工件以(yi)減少不(bu)均勻(yun)(yun)的熱應力和(he)(he)不(bu)均勻(yun)(yun)的組織應力以(yi)減少變(bian)形(xing)。夾緊方法可以(yi)改變(bian)。圓盤(pan)部件垂(chui)直于(yu)油面，軸(zhou)部件垂(chui)直安裝(zhuang)。使(shi)用補償墊(dian)圈(quan)和(he)(he)支(zhi)撐墊(dian)圈(quan)。 ，花鍵孔部件可使(shi)用滲(shen)碳(tan)芯軸(zhou)，疊(die)加墊(dian)圈(quan)等。

（2）加工

當(dang)熱(re)處理(li)(li)(li)是(shi)工(gong)(gong)(gong)件加(jia)工(gong)(gong)(gong)過程(cheng)(cheng)的(de)(de)(de)最后一步時(shi)，熱(re)處理(li)(li)(li)變(bian)(bian)(bian)(bian)形(xing)的(de)(de)(de)允許值應(ying)滿足圖紙上指定(ding)的(de)(de)(de)工(gong)(gong)(gong)件尺(chi)(chi)寸(cun)，變(bian)(bian)(bian)(bian)形(xing)變(bian)(bian)(bian)(bian)量(liang)(liang)(liang)應(ying)根(gen)據(ju)(ju)前一加(jia)工(gong)(gong)(gong)的(de)(de)(de)尺(chi)(chi)寸(cun)確定(ding)。因(yin)此，根(gen)據(ju)(ju)工(gong)(gong)(gong)件的(de)(de)(de)變(bian)(bian)(bian)(bian)形(xing)，應(ying)在熱(re)處理(li)(li)(li)之前進(jin)行尺(chi)(chi)寸(cun)的(de)(de)(de)預校正，以使(shi)熱(re)處理(li)(li)(li)變(bian)(bian)(bian)(bian)形(xing)在合(he)格(ge)范圍內(nei)。當(dang)熱(re)處理(li)(li)(li)是(shi)中間過程(cheng)(cheng)時(shi)，應(ying)將(jiang)熱(re)處理(li)(li)(li)前的(de)(de)(de)加(jia)工(gong)(gong)(gong)余量(liang)(liang)(liang)視為加(jia)工(gong)(gong)(gong)余量(liang)(liang)(liang)和熱(re)處理(li)(li)(li)變(bian)(bian)(bian)(bian)形(xing)的(de)(de)(de)總和。通常，加(jia)工(gong)(gong)(gong)余量(liang)(liang)(liang)容(rong)易確定(ding)，并且由于(yu)許多影響因(yin)素(su)而使(shi)熱(re)處理(li)(li)(li)更加(jia)復(fu)雜，因(yin)此留有足夠的(de)(de)(de)加(jia)工(gong)(gong)(gong)余量(liang)(liang)(liang)用于(yu)加(jia)工(gong)(gong)(gong)，其(qi)余的(de)(de)(de)可以用作熱(re)處理(li)(li)(li)容(rong)許變(bian)(bian)(bian)(bian)形(xing)變(bian)(bian)(bian)(bian)量(liang)(liang)(liang)。熱(re)處理(li)(li)(li)后的(de)(de)(de)加(jia)工(gong)(gong)(gong)后，根(gen)據(ju)(ju)工(gong)(gong)(gong)件的(de)(de)(de)變(bian)(bian)(bian)(bian)形(xing)規律，采用抗變(bian)(bian)(bian)(bian)形(xing)和收縮端預擴孔，以提高淬火后的(de)(de)(de)變(bian)(bian)(bian)(bian)形(xing)合(he)格(ge)率。

（3）使用適當(dang)的(de)媒體

鋼熱處理廠家在確保相同(tong)的(de)硬度(du)(du)要求的(de)前提(ti)下，嘗試使用(yong)油(you)性(xing)(xing)介(jie)質(zhi)。實驗和實踐證明，在沒有其(qi)他(ta)條件的(de)前提(ti)下，油(you)性(xing)(xing)介(jie)質(zhi)的(de)冷(leng)卻速(su)度(du)(du)較慢，而水(shui)性(xing)(xing)介(jie)質(zhi)的(de)冷(leng)卻速(su)度(du)(du)則相對較快。而且，與油(you)性(xing)(xing)介(jie)質(zhi)相比(bi)，水(shui)溫變(bian)化對水(shui)性(xing)(xing)介(jie)質(zhi)的(de)冷(leng)卻特性(xing)(xing)影響(xiang)更(geng)大。在相同(tong)的(de)熱處理(li)條件下，與水(shui)性(xing)(xing)介(jie)質(zhi)相比(bi)，淬火后油(you)性(xing)(xing)介(jie)質(zhi)的(de)變(bian)形量相對較小。

鋼熱處理廠家可以改(gai)善工(gong)(gong)件(jian)(jian)的機械性能，并提高工(gong)(gong)件(jian)(jian)的強(qiang)度和硬(ying)度，但不可避免地產生變(bian)形(xing)效果。現階(jie)段，我們必須重視中國(guo)熱處理技術(shu)和設備的改(gai)進，不斷(duan)學習國(guo)外先進技術(shu)，提高熱處理工(gong)(gong)件(jian)(jian)的質(zhi)量和合格率，為中國(guo)熱處理行業(ye)做出貢獻。
