（1）使用合理的夾緊(jin)方(fang)法和固定裝置

目的均勻(yun)(yun)加熱(re)和冷卻工件(jian)以減少(shao)不(bu)均勻(yun)(yun)的熱(re)應力(li)(li)和不(bu)均勻(yun)(yun)的組織應力(li)(li)以減少(shao)變(bian)形(xing)。夾緊方法可以改變(bian)。圓(yuan)盤部件(jian)垂直于油面，軸部件(jian)垂直安裝。使(shi)用(yong)補償墊圈(quan)和支(zhi)撐墊圈(quan)。 ，花鍵孔(kong)部件(jian)可使(shi)用(yong)滲碳芯軸，疊加墊圈(quan)等。

（2）加工

當(dang)熱(re)處(chu)(chu)(chu)理(li)(li)(li)是工(gong)(gong)(gong)(gong)(gong)件(jian)加(jia)工(gong)(gong)(gong)(gong)(gong)過程的(de)(de)最(zui)后(hou)一步時(shi)，熱(re)處(chu)(chu)(chu)理(li)(li)(li)變(bian)(bian)形的(de)(de)允許(xu)值應(ying)滿足圖紙上指定(ding)的(de)(de)工(gong)(gong)(gong)(gong)(gong)件(jian)尺(chi)寸(cun)，變(bian)(bian)形變(bian)(bian)量應(ying)根(gen)(gen)據前(qian)一加(jia)工(gong)(gong)(gong)(gong)(gong)的(de)(de)尺(chi)寸(cun)確(que)定(ding)。因此，根(gen)(gen)據工(gong)(gong)(gong)(gong)(gong)件(jian)的(de)(de)變(bian)(bian)形，應(ying)在熱(re)處(chu)(chu)(chu)理(li)(li)(li)之前(qian)進行尺(chi)寸(cun)的(de)(de)預(yu)校(xiao)正(zheng)，以(yi)使熱(re)處(chu)(chu)(chu)理(li)(li)(li)變(bian)(bian)形在合格范(fan)圍內(nei)。當(dang)熱(re)處(chu)(chu)(chu)理(li)(li)(li)是中間(jian)過程時(shi)，應(ying)將熱(re)處(chu)(chu)(chu)理(li)(li)(li)前(qian)的(de)(de)加(jia)工(gong)(gong)(gong)(gong)(gong)余量視為加(jia)工(gong)(gong)(gong)(gong)(gong)余量和(he)熱(re)處(chu)(chu)(chu)理(li)(li)(li)變(bian)(bian)形的(de)(de)總和(he)。通(tong)常，加(jia)工(gong)(gong)(gong)(gong)(gong)余量容易確(que)定(ding)，并且由于許(xu)多影響因素而使熱(re)處(chu)(chu)(chu)理(li)(li)(li)更加(jia)復雜，因此留(liu)有足夠的(de)(de)加(jia)工(gong)(gong)(gong)(gong)(gong)余量用(yong)于加(jia)工(gong)(gong)(gong)(gong)(gong)，其余的(de)(de)可(ke)以(yi)用(yong)作熱(re)處(chu)(chu)(chu)理(li)(li)(li)容許(xu)變(bian)(bian)形變(bian)(bian)量。熱(re)處(chu)(chu)(chu)理(li)(li)(li)后(hou)的(de)(de)加(jia)工(gong)(gong)(gong)(gong)(gong)后(hou)，根(gen)(gen)據工(gong)(gong)(gong)(gong)(gong)件(jian)的(de)(de)變(bian)(bian)形規律，采用(yong)抗變(bian)(bian)形和(he)收縮端預(yu)擴(kuo)孔，以(yi)提高淬火(huo)后(hou)的(de)(de)變(bian)(bian)形合格率。

（3）使用(yong)適當的(de)媒(mei)體

鋼熱處理廠家在確保相(xiang)同(tong)的(de)(de)硬度要求(qiu)的(de)(de)前(qian)提下，嘗試使(shi)用油性(xing)介(jie)質(zhi)(zhi)(zhi)。實驗和實踐證明(ming)，在沒有其他條件(jian)的(de)(de)前(qian)提下，油性(xing)介(jie)質(zhi)(zhi)(zhi)的(de)(de)冷(leng)卻速(su)度較慢，而水(shui)(shui)(shui)性(xing)介(jie)質(zhi)(zhi)(zhi)的(de)(de)冷(leng)卻速(su)度則相(xiang)對較快。而且，與油性(xing)介(jie)質(zhi)(zhi)(zhi)相(xiang)比，水(shui)(shui)(shui)溫變化對水(shui)(shui)(shui)性(xing)介(jie)質(zhi)(zhi)(zhi)的(de)(de)冷(leng)卻特性(xing)影響更大。在相(xiang)同(tong)的(de)(de)熱(re)處理條件(jian)下，與水(shui)(shui)(shui)性(xing)介(jie)質(zhi)(zhi)(zhi)相(xiang)比，淬(cui)火后油性(xing)介(jie)質(zhi)(zhi)(zhi)的(de)(de)變形量相(xiang)對較小。

鋼熱處理廠家可(ke)以改善工件(jian)(jian)的(de)機械性能(neng)，并提高工件(jian)(jian)的(de)強度(du)和(he)硬度(du)，但不可(ke)避(bi)免地(di)產(chan)生變形效(xiao)果。現階(jie)段(duan)，我們必須(xu)重視(shi)中國(guo)熱(re)處(chu)理(li)(li)技(ji)術(shu)(shu)和(he)設(she)備的(de)改進，不斷(duan)學習國(guo)外先(xian)進技(ji)術(shu)(shu)，提高熱(re)處(chu)理(li)(li)工件(jian)(jian)的(de)質量和(he)合格率，為中國(guo)熱(re)處(chu)理(li)(li)行業做(zuo)出貢獻。
