（1）使用合(he)理的夾緊(jin)方法和(he)固(gu)定裝置

目的均勻加(jia)熱和冷卻工件以減(jian)少不均勻的熱應力(li)和不均勻的組織應力(li)以減(jian)少變(bian)(bian)形。夾(jia)緊方(fang)法可以改變(bian)(bian)。圓盤部件垂(chui)(chui)直(zhi)于油面，軸部件垂(chui)(chui)直(zhi)安裝(zhuang)。使(shi)用(yong)(yong)補(bu)償墊(dian)圈(quan)和支撐墊(dian)圈(quan)。 ，花鍵孔(kong)部件可使(shi)用(yong)(yong)滲碳芯軸，疊加(jia)墊(dian)圈(quan)等。

（2）加工

當熱(re)(re)(re)(re)處(chu)(chu)(chu)理(li)(li)(li)(li)是工(gong)(gong)(gong)(gong)(gong)件加(jia)工(gong)(gong)(gong)(gong)(gong)過(guo)程(cheng)的(de)(de)(de)最后一(yi)步時，熱(re)(re)(re)(re)處(chu)(chu)(chu)理(li)(li)(li)(li)變(bian)(bian)形(xing)(xing)的(de)(de)(de)允許值應滿足圖紙上指定的(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)件尺寸，變(bian)(bian)形(xing)(xing)變(bian)(bian)量(liang)(liang)(liang)應根(gen)據前(qian)(qian)一(yi)加(jia)工(gong)(gong)(gong)(gong)(gong)的(de)(de)(de)尺寸確定。因(yin)此(ci)，根(gen)據工(gong)(gong)(gong)(gong)(gong)件的(de)(de)(de)變(bian)(bian)形(xing)(xing)，應在熱(re)(re)(re)(re)處(chu)(chu)(chu)理(li)(li)(li)(li)之前(qian)(qian)進行尺寸的(de)(de)(de)預校正，以(yi)使熱(re)(re)(re)(re)處(chu)(chu)(chu)理(li)(li)(li)(li)變(bian)(bian)形(xing)(xing)在合(he)格范圍內(nei)。當熱(re)(re)(re)(re)處(chu)(chu)(chu)理(li)(li)(li)(li)是中間過(guo)程(cheng)時，應將熱(re)(re)(re)(re)處(chu)(chu)(chu)理(li)(li)(li)(li)前(qian)(qian)的(de)(de)(de)加(jia)工(gong)(gong)(gong)(gong)(gong)余量(liang)(liang)(liang)視為(wei)加(jia)工(gong)(gong)(gong)(gong)(gong)余量(liang)(liang)(liang)和熱(re)(re)(re)(re)處(chu)(chu)(chu)理(li)(li)(li)(li)變(bian)(bian)形(xing)(xing)的(de)(de)(de)總和。通(tong)常，加(jia)工(gong)(gong)(gong)(gong)(gong)余量(liang)(liang)(liang)容易確定，并(bing)且由于許多影響因(yin)素而使熱(re)(re)(re)(re)處(chu)(chu)(chu)理(li)(li)(li)(li)更加(jia)復(fu)雜，因(yin)此(ci)留有足夠的(de)(de)(de)加(jia)工(gong)(gong)(gong)(gong)(gong)余量(liang)(liang)(liang)用(yong)(yong)于加(jia)工(gong)(gong)(gong)(gong)(gong)，其(qi)余的(de)(de)(de)可以(yi)用(yong)(yong)作(zuo)熱(re)(re)(re)(re)處(chu)(chu)(chu)理(li)(li)(li)(li)容許變(bian)(bian)形(xing)(xing)變(bian)(bian)量(liang)(liang)(liang)。熱(re)(re)(re)(re)處(chu)(chu)(chu)理(li)(li)(li)(li)后的(de)(de)(de)加(jia)工(gong)(gong)(gong)(gong)(gong)后，根(gen)據工(gong)(gong)(gong)(gong)(gong)件的(de)(de)(de)變(bian)(bian)形(xing)(xing)規律，采用(yong)(yong)抗變(bian)(bian)形(xing)(xing)和收縮(suo)端預擴(kuo)孔，以(yi)提(ti)高淬(cui)火后的(de)(de)(de)變(bian)(bian)形(xing)(xing)合(he)格率。

（3）使用適當的(de)媒體

鋼熱處理廠家在確保相同的(de)(de)硬度要求的(de)(de)前提下(xia)，嘗試使用油(you)(you)性(xing)(xing)介(jie)(jie)(jie)(jie)質(zhi)(zhi)。實驗(yan)和實踐(jian)證明，在沒有其他(ta)條件(jian)的(de)(de)前提下(xia)，油(you)(you)性(xing)(xing)介(jie)(jie)(jie)(jie)質(zhi)(zhi)的(de)(de)冷(leng)卻(que)速度較慢，而水性(xing)(xing)介(jie)(jie)(jie)(jie)質(zhi)(zhi)的(de)(de)冷(leng)卻(que)速度則相對較快。而且，與油(you)(you)性(xing)(xing)介(jie)(jie)(jie)(jie)質(zhi)(zhi)相比(bi)，水溫變化對水性(xing)(xing)介(jie)(jie)(jie)(jie)質(zhi)(zhi)的(de)(de)冷(leng)卻(que)特性(xing)(xing)影響更大。在相同的(de)(de)熱處理條件(jian)下(xia)，與水性(xing)(xing)介(jie)(jie)(jie)(jie)質(zhi)(zhi)相比(bi)，淬(cui)火(huo)后油(you)(you)性(xing)(xing)介(jie)(jie)(jie)(jie)質(zhi)(zhi)的(de)(de)變形(xing)量相對較小。

鋼熱處理廠家可以改(gai)善(shan)工(gong)件的(de)(de)機械(xie)性能，并(bing)提(ti)高工(gong)件的(de)(de)強度和(he)硬度，但不(bu)可避免地(di)產(chan)生(sheng)變(bian)形效(xiao)果(guo)。現階段，我們(men)必須(xu)重視中國(guo)熱(re)處(chu)理技術和(he)設(she)備的(de)(de)改(gai)進，不(bu)斷學習國(guo)外先進技術，提(ti)高熱(re)處(chu)理工(gong)件的(de)(de)質量(liang)和(he)合格率，為中國(guo)熱(re)處(chu)理行業做(zuo)出貢(gong)獻。
