（1）使(shi)用(yong)合(he)理的夾緊(jin)方法和固定裝(zhuang)置

目的(de)均勻(yun)(yun)(yun)加(jia)(jia)熱和冷卻工件以(yi)減(jian)少不均勻(yun)(yun)(yun)的(de)熱應力(li)和不均勻(yun)(yun)(yun)的(de)組織應力(li)以(yi)減(jian)少變(bian)形(xing)。夾(jia)緊(jin)方法可以(yi)改變(bian)。圓(yuan)盤部件垂直(zhi)于油面，軸部件垂直(zhi)安(an)裝。使用補償墊圈(quan)和支撐墊圈(quan)。 ，花(hua)鍵孔部件可使用滲碳芯(xin)軸，疊加(jia)(jia)墊圈(quan)等(deng)。

（2）加工

當熱(re)(re)處(chu)理(li)(li)是工(gong)(gong)件(jian)加(jia)工(gong)(gong)過(guo)程的(de)(de)(de)(de)最后一(yi)步時，熱(re)(re)處(chu)理(li)(li)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)形(xing)(xing)的(de)(de)(de)(de)允許(xu)值應(ying)滿足圖紙上指(zhi)定(ding)(ding)的(de)(de)(de)(de)工(gong)(gong)件(jian)尺寸(cun)(cun)(cun)，變(bian)(bian)(bian)(bian)(bian)(bian)(bian)形(xing)(xing)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)量(liang)應(ying)根(gen)據前(qian)一(yi)加(jia)工(gong)(gong)的(de)(de)(de)(de)尺寸(cun)(cun)(cun)確(que)定(ding)(ding)。因此(ci)，根(gen)據工(gong)(gong)件(jian)的(de)(de)(de)(de)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)形(xing)(xing)，應(ying)在熱(re)(re)處(chu)理(li)(li)之前(qian)進行尺寸(cun)(cun)(cun)的(de)(de)(de)(de)預校正，以使熱(re)(re)處(chu)理(li)(li)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)形(xing)(xing)在合(he)格范(fan)圍內。當熱(re)(re)處(chu)理(li)(li)是中間(jian)過(guo)程時，應(ying)將熱(re)(re)處(chu)理(li)(li)前(qian)的(de)(de)(de)(de)加(jia)工(gong)(gong)余量(liang)視為加(jia)工(gong)(gong)余量(liang)和(he)(he)熱(re)(re)處(chu)理(li)(li)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)形(xing)(xing)的(de)(de)(de)(de)總和(he)(he)。通常，加(jia)工(gong)(gong)余量(liang)容易確(que)定(ding)(ding)，并(bing)且由于許(xu)多影響因素而使熱(re)(re)處(chu)理(li)(li)更加(jia)復雜，因此(ci)留有足夠(gou)的(de)(de)(de)(de)加(jia)工(gong)(gong)余量(liang)用于加(jia)工(gong)(gong)，其余的(de)(de)(de)(de)可(ke)以用作熱(re)(re)處(chu)理(li)(li)容許(xu)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)形(xing)(xing)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)量(liang)。熱(re)(re)處(chu)理(li)(li)后的(de)(de)(de)(de)加(jia)工(gong)(gong)后，根(gen)據工(gong)(gong)件(jian)的(de)(de)(de)(de)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)形(xing)(xing)規律，采用抗變(bian)(bian)(bian)(bian)(bian)(bian)(bian)形(xing)(xing)和(he)(he)收縮(suo)端預擴孔，以提高(gao)淬火后的(de)(de)(de)(de)變(bian)(bian)(bian)(bian)(bian)(bian)(bian)形(xing)(xing)合(he)格率(lv)。

（3）使(shi)用適當(dang)的媒體

鋼熱處理廠家在確(que)保相同的(de)(de)(de)硬(ying)度(du)要(yao)求(qiu)的(de)(de)(de)前提(ti)下，嘗試(shi)使(shi)用(yong)油性(xing)(xing)介(jie)(jie)質(zhi)。實驗和實踐證(zheng)明，在沒有其他(ta)條件(jian)的(de)(de)(de)前提(ti)下，油性(xing)(xing)介(jie)(jie)質(zhi)的(de)(de)(de)冷(leng)卻速(su)度(du)較慢(man)，而(er)水(shui)性(xing)(xing)介(jie)(jie)質(zhi)的(de)(de)(de)冷(leng)卻速(su)度(du)則相對較快(kuai)。而(er)且，與(yu)油性(xing)(xing)介(jie)(jie)質(zhi)相比，水(shui)溫變(bian)化對水(shui)性(xing)(xing)介(jie)(jie)質(zhi)的(de)(de)(de)冷(leng)卻特性(xing)(xing)影響更(geng)大。在相同的(de)(de)(de)熱處理條件(jian)下，與(yu)水(shui)性(xing)(xing)介(jie)(jie)質(zhi)相比，淬火(huo)后油性(xing)(xing)介(jie)(jie)質(zhi)的(de)(de)(de)變(bian)形量相對較小。

鋼熱處理廠家可(ke)以改善工件(jian)的(de)機械(xie)性能(neng)，并提(ti)高(gao)工件(jian)的(de)強度(du)和硬度(du)，但不可(ke)避免地產生變形效(xiao)果。現階(jie)段，我(wo)們(men)必須重視中國(guo)熱(re)處(chu)理技術和設(she)備的(de)改進，不斷(duan)學(xue)習國(guo)外先進技術，提(ti)高(gao)熱(re)處(chu)理工件(jian)的(de)質(zhi)量和合(he)格(ge)率(lv)，為中國(guo)熱(re)處(chu)理行(xing)業做出貢獻。
