（1）使用合理(li)的(de)夾緊方法(fa)和固定裝置

目的均(jun)(jun)(jun)勻(yun)加熱和冷卻(que)工件(jian)(jian)以(yi)減少不(bu)均(jun)(jun)(jun)勻(yun)的熱應力和不(bu)均(jun)(jun)(jun)勻(yun)的組織應力以(yi)減少變形。夾緊方法可(ke)以(yi)改變。圓盤(pan)部件(jian)(jian)垂直于油(you)面，軸(zhou)部件(jian)(jian)垂直安裝(zhuang)。使用補償墊圈(quan)和支撐墊圈(quan)。 ，花鍵孔(kong)部件(jian)(jian)可(ke)使用滲碳芯軸(zhou)，疊加墊圈(quan)等。

（2）加工

當熱(re)處(chu)(chu)(chu)理(li)(li)是工(gong)(gong)件加(jia)工(gong)(gong)過程的(de)最后一步時(shi)，熱(re)處(chu)(chu)(chu)理(li)(li)變(bian)(bian)(bian)(bian)(bian)(bian)形(xing)(xing)的(de)允許值(zhi)應滿足(zu)(zu)圖紙上指定(ding)的(de)工(gong)(gong)件尺(chi)寸(cun)，變(bian)(bian)(bian)(bian)(bian)(bian)形(xing)(xing)變(bian)(bian)(bian)(bian)(bian)(bian)量(liang)應根據前一加(jia)工(gong)(gong)的(de)尺(chi)寸(cun)確(que)定(ding)。因(yin)此(ci)，根據工(gong)(gong)件的(de)變(bian)(bian)(bian)(bian)(bian)(bian)形(xing)(xing)，應在(zai)熱(re)處(chu)(chu)(chu)理(li)(li)之(zhi)前進行尺(chi)寸(cun)的(de)預校正(zheng)，以使(shi)熱(re)處(chu)(chu)(chu)理(li)(li)變(bian)(bian)(bian)(bian)(bian)(bian)形(xing)(xing)在(zai)合格范圍內。當熱(re)處(chu)(chu)(chu)理(li)(li)是中間過程時(shi)，應將熱(re)處(chu)(chu)(chu)理(li)(li)前的(de)加(jia)工(gong)(gong)余(yu)(yu)量(liang)視為加(jia)工(gong)(gong)余(yu)(yu)量(liang)和(he)熱(re)處(chu)(chu)(chu)理(li)(li)變(bian)(bian)(bian)(bian)(bian)(bian)形(xing)(xing)的(de)總和(he)。通常，加(jia)工(gong)(gong)余(yu)(yu)量(liang)容(rong)易(yi)確(que)定(ding)，并且(qie)由于許多影響因(yin)素而使(shi)熱(re)處(chu)(chu)(chu)理(li)(li)更加(jia)復雜，因(yin)此(ci)留(liu)有足(zu)(zu)夠的(de)加(jia)工(gong)(gong)余(yu)(yu)量(liang)用于加(jia)工(gong)(gong)，其余(yu)(yu)的(de)可以用作熱(re)處(chu)(chu)(chu)理(li)(li)容(rong)許變(bian)(bian)(bian)(bian)(bian)(bian)形(xing)(xing)變(bian)(bian)(bian)(bian)(bian)(bian)量(liang)。熱(re)處(chu)(chu)(chu)理(li)(li)后的(de)加(jia)工(gong)(gong)后，根據工(gong)(gong)件的(de)變(bian)(bian)(bian)(bian)(bian)(bian)形(xing)(xing)規律，采用抗變(bian)(bian)(bian)(bian)(bian)(bian)形(xing)(xing)和(he)收縮(suo)端預擴孔，以提高淬火(huo)后的(de)變(bian)(bian)(bian)(bian)(bian)(bian)形(xing)(xing)合格率。

（3）使用適當的媒體

鋼熱處理廠家在(zai)確保相(xiang)(xiang)同的(de)(de)(de)硬(ying)度要求的(de)(de)(de)前(qian)提下，嘗試使用油(you)(you)性(xing)(xing)介(jie)質(zhi)(zhi)。實驗(yan)和實踐證明，在(zai)沒(mei)有其他(ta)條件的(de)(de)(de)前(qian)提下，油(you)(you)性(xing)(xing)介(jie)質(zhi)(zhi)的(de)(de)(de)冷(leng)卻速度較慢，而水性(xing)(xing)介(jie)質(zhi)(zhi)的(de)(de)(de)冷(leng)卻速度則(ze)相(xiang)(xiang)對(dui)較快。而且(qie)，與(yu)油(you)(you)性(xing)(xing)介(jie)質(zhi)(zhi)相(xiang)(xiang)比，水溫變化對(dui)水性(xing)(xing)介(jie)質(zhi)(zhi)的(de)(de)(de)冷(leng)卻特性(xing)(xing)影響更大。在(zai)相(xiang)(xiang)同的(de)(de)(de)熱處理條件下，與(yu)水性(xing)(xing)介(jie)質(zhi)(zhi)相(xiang)(xiang)比，淬火(huo)后油(you)(you)性(xing)(xing)介(jie)質(zhi)(zhi)的(de)(de)(de)變形量相(xiang)(xiang)對(dui)較小。

鋼熱處理廠家可(ke)以改善工(gong)(gong)件(jian)(jian)的機械性能，并提高(gao)(gao)工(gong)(gong)件(jian)(jian)的強(qiang)度和(he)硬(ying)度，但不可(ke)避免地產生變形效果(guo)。現階段(duan)，我們必須重視中國熱(re)處(chu)理(li)技(ji)術和(he)設(she)備(bei)的改進，不斷(duan)學習國外先進技(ji)術，提高(gao)(gao)熱(re)處(chu)理(li)工(gong)(gong)件(jian)(jian)的質(zhi)量和(he)合格率，為(wei)中國熱(re)處(chu)理(li)行業做(zuo)出貢獻。
