（1）使用(yong)合理的夾緊方法和固定裝置

目的均(jun)勻(yun)加熱和冷(leng)卻工件(jian)(jian)以減(jian)少不均(jun)勻(yun)的熱應力和不均(jun)勻(yun)的組織應力以減(jian)少變形。夾緊方法可以改變。圓盤部件(jian)(jian)垂直(zhi)于油面，軸部件(jian)(jian)垂直(zhi)安裝。使用補(bu)償墊圈和支撐墊圈。 ，花(hua)鍵孔部件(jian)(jian)可使用滲碳芯軸，疊加墊圈等。

（2）加工

當(dang)熱(re)處(chu)理是工(gong)(gong)(gong)(gong)件加(jia)工(gong)(gong)(gong)(gong)過程的(de)(de)(de)最(zui)后(hou)一步時(shi)(shi)，熱(re)處(chu)理變(bian)(bian)形(xing)的(de)(de)(de)允許(xu)值應(ying)滿足(zu)圖紙上指定(ding)(ding)的(de)(de)(de)工(gong)(gong)(gong)(gong)件尺寸(cun)，變(bian)(bian)形(xing)變(bian)(bian)量應(ying)根(gen)據前(qian)一加(jia)工(gong)(gong)(gong)(gong)的(de)(de)(de)尺寸(cun)確(que)定(ding)(ding)。因(yin)此(ci)，根(gen)據工(gong)(gong)(gong)(gong)件的(de)(de)(de)變(bian)(bian)形(xing)，應(ying)在熱(re)處(chu)理之前(qian)進行尺寸(cun)的(de)(de)(de)預校正，以使熱(re)處(chu)理變(bian)(bian)形(xing)在合格范圍內。當(dang)熱(re)處(chu)理是中間過程時(shi)(shi)，應(ying)將熱(re)處(chu)理前(qian)的(de)(de)(de)加(jia)工(gong)(gong)(gong)(gong)余(yu)(yu)量視(shi)為加(jia)工(gong)(gong)(gong)(gong)余(yu)(yu)量和熱(re)處(chu)理變(bian)(bian)形(xing)的(de)(de)(de)總和。通常，加(jia)工(gong)(gong)(gong)(gong)余(yu)(yu)量容(rong)易確(que)定(ding)(ding)，并且由于許(xu)多影響因(yin)素而使熱(re)處(chu)理更加(jia)復雜，因(yin)此(ci)留有足(zu)夠的(de)(de)(de)加(jia)工(gong)(gong)(gong)(gong)余(yu)(yu)量用(yong)(yong)于加(jia)工(gong)(gong)(gong)(gong)，其余(yu)(yu)的(de)(de)(de)可以用(yong)(yong)作(zuo)熱(re)處(chu)理容(rong)許(xu)變(bian)(bian)形(xing)變(bian)(bian)量。熱(re)處(chu)理后(hou)的(de)(de)(de)加(jia)工(gong)(gong)(gong)(gong)后(hou)，根(gen)據工(gong)(gong)(gong)(gong)件的(de)(de)(de)變(bian)(bian)形(xing)規律，采用(yong)(yong)抗變(bian)(bian)形(xing)和收縮(suo)端預擴孔，以提高淬火(huo)后(hou)的(de)(de)(de)變(bian)(bian)形(xing)合格率。

（3）使用適(shi)當的媒體

鋼熱處理廠家在(zai)確保相同(tong)的(de)(de)硬(ying)度(du)要(yao)求的(de)(de)前(qian)提(ti)下，嘗試(shi)使(shi)用(yong)油(you)性(xing)介質(zhi)(zhi)。實(shi)驗和實(shi)踐證明，在(zai)沒有(you)其他(ta)條(tiao)件的(de)(de)前(qian)提(ti)下，油(you)性(xing)介質(zhi)(zhi)的(de)(de)冷(leng)卻(que)速度(du)較(jiao)慢(man)，而(er)水性(xing)介質(zhi)(zhi)的(de)(de)冷(leng)卻(que)速度(du)則相對較(jiao)快(kuai)。而(er)且，與(yu)油(you)性(xing)介質(zhi)(zhi)相比(bi)，水溫變化對水性(xing)介質(zhi)(zhi)的(de)(de)冷(leng)卻(que)特(te)性(xing)影響更大。在(zai)相同(tong)的(de)(de)熱處理條(tiao)件下，與(yu)水性(xing)介質(zhi)(zhi)相比(bi)，淬火后油(you)性(xing)介質(zhi)(zhi)的(de)(de)變形(xing)量(liang)相對較(jiao)小(xiao)。

鋼熱處理廠家可以(yi)改(gai)善工(gong)件(jian)的機械(xie)性能，并提(ti)高工(gong)件(jian)的強度和硬度，但(dan)不可避免地產生變形效果(guo)。現(xian)階段，我(wo)們必須重視(shi)中國熱(re)處理(li)(li)技(ji)術和設(she)備的改(gai)進(jin)，不斷學(xue)習國外先進(jin)技(ji)術，提(ti)高熱(re)處理(li)(li)工(gong)件(jian)的質量和合(he)格率，為中國熱(re)處理(li)(li)行業做出貢獻。
