（1）使用合理的夾緊方法和固定裝置(zhi)

目(mu)的(de)均勻加(jia)熱和冷(leng)卻(que)工(gong)件以(yi)(yi)減少不均勻的(de)熱應(ying)力和不均勻的(de)組織應(ying)力以(yi)(yi)減少變形。夾緊(jin)方(fang)法可(ke)以(yi)(yi)改變。圓(yuan)盤(pan)部件垂直(zhi)(zhi)于油面，軸(zhou)部件垂直(zhi)(zhi)安裝。使用補償墊(dian)圈和支(zhi)撐墊(dian)圈。 ，花鍵(jian)孔部件可(ke)使用滲(shen)碳芯軸(zhou)，疊加(jia)墊(dian)圈等。

（2）加工

當(dang)熱處(chu)理(li)(li)(li)(li)是(shi)工(gong)(gong)(gong)(gong)件加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)過程(cheng)(cheng)的(de)(de)最后(hou)一步(bu)時(shi)，熱處(chu)理(li)(li)(li)(li)變(bian)(bian)(bian)形(xing)(xing)的(de)(de)允(yun)許值應(ying)滿足圖(tu)紙上指定的(de)(de)工(gong)(gong)(gong)(gong)件尺(chi)寸，變(bian)(bian)(bian)形(xing)(xing)變(bian)(bian)(bian)量(liang)(liang)應(ying)根據(ju)前(qian)一加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)的(de)(de)尺(chi)寸確(que)定。因此(ci)，根據(ju)工(gong)(gong)(gong)(gong)件的(de)(de)變(bian)(bian)(bian)形(xing)(xing)，應(ying)在熱處(chu)理(li)(li)(li)(li)之(zhi)前(qian)進行尺(chi)寸的(de)(de)預(yu)校正，以使熱處(chu)理(li)(li)(li)(li)變(bian)(bian)(bian)形(xing)(xing)在合格范圍內。當(dang)熱處(chu)理(li)(li)(li)(li)是(shi)中間(jian)過程(cheng)(cheng)時(shi)，應(ying)將(jiang)熱處(chu)理(li)(li)(li)(li)前(qian)的(de)(de)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)余(yu)量(liang)(liang)視為加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)余(yu)量(liang)(liang)和熱處(chu)理(li)(li)(li)(li)變(bian)(bian)(bian)形(xing)(xing)的(de)(de)總和。通常，加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)余(yu)量(liang)(liang)容(rong)易確(que)定，并且由于許多(duo)影響(xiang)因素而使熱處(chu)理(li)(li)(li)(li)更加(jia)(jia)(jia)(jia)復雜，因此(ci)留有足夠的(de)(de)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)余(yu)量(liang)(liang)用(yong)于加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)，其余(yu)的(de)(de)可以用(yong)作熱處(chu)理(li)(li)(li)(li)容(rong)許變(bian)(bian)(bian)形(xing)(xing)變(bian)(bian)(bian)量(liang)(liang)。熱處(chu)理(li)(li)(li)(li)后(hou)的(de)(de)加(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)后(hou)，根據(ju)工(gong)(gong)(gong)(gong)件的(de)(de)變(bian)(bian)(bian)形(xing)(xing)規律(lv)，采用(yong)抗變(bian)(bian)(bian)形(xing)(xing)和收縮端預(yu)擴孔，以提高淬火后(hou)的(de)(de)變(bian)(bian)(bian)形(xing)(xing)合格率。

（3）使用適(shi)當的媒體

鋼熱處理廠家在(zai)確保相(xiang)(xiang)同(tong)的(de)(de)硬度(du)要(yao)求的(de)(de)前(qian)提(ti)(ti)下(xia)，嘗(chang)試使用油(you)(you)性(xing)介(jie)(jie)質(zhi)。實驗(yan)和實踐證明，在(zai)沒(mei)有其他(ta)條(tiao)件的(de)(de)前(qian)提(ti)(ti)下(xia)，油(you)(you)性(xing)介(jie)(jie)質(zhi)的(de)(de)冷卻速(su)度(du)較(jiao)慢(man)，而水(shui)性(xing)介(jie)(jie)質(zhi)的(de)(de)冷卻速(su)度(du)則相(xiang)(xiang)對(dui)(dui)較(jiao)快。而且，與(yu)油(you)(you)性(xing)介(jie)(jie)質(zhi)相(xiang)(xiang)比，水(shui)溫變化(hua)對(dui)(dui)水(shui)性(xing)介(jie)(jie)質(zhi)的(de)(de)冷卻特性(xing)影響更大。在(zai)相(xiang)(xiang)同(tong)的(de)(de)熱處理條(tiao)件下(xia)，與(yu)水(shui)性(xing)介(jie)(jie)質(zhi)相(xiang)(xiang)比，淬火后油(you)(you)性(xing)介(jie)(jie)質(zhi)的(de)(de)變形量相(xiang)(xiang)對(dui)(dui)較(jiao)小。

鋼熱處理廠家可以改(gai)善(shan)工件(jian)的(de)機械性能，并提(ti)高(gao)工件(jian)的(de)強度和(he)硬度，但不(bu)可避免地產(chan)生變形效果。現階段，我們必須重視中(zhong)國熱(re)處理技(ji)術和(he)設備(bei)的(de)改(gai)進，不(bu)斷學(xue)習國外先進技(ji)術，提(ti)高(gao)熱(re)處理工件(jian)的(de)質量和(he)合格率，為中(zhong)國熱(re)處理行(xing)業做出(chu)貢獻。
