（1）使用合理(li)的夾(jia)緊方(fang)法和(he)固(gu)定裝(zhuang)置

目(mu)的(de)均(jun)勻加熱和冷卻(que)工件以減(jian)少(shao)不(bu)均(jun)勻的(de)熱應(ying)力(li)和不(bu)均(jun)勻的(de)組織應(ying)力(li)以減(jian)少(shao)變(bian)形(xing)。夾緊方(fang)法可以改(gai)變(bian)。圓盤(pan)部件垂直于油(you)面，軸部件垂直安(an)裝。使(shi)用(yong)補(bu)償墊(dian)(dian)圈(quan)和支撐墊(dian)(dian)圈(quan)。 ，花鍵孔部件可使(shi)用(yong)滲碳(tan)芯軸，疊加墊(dian)(dian)圈(quan)等(deng)。

（2）加工

當熱(re)(re)(re)處(chu)理(li)是工(gong)(gong)(gong)(gong)(gong)件加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)過程的(de)(de)最后一步時(shi)，熱(re)(re)(re)處(chu)理(li)變(bian)(bian)(bian)(bian)(bian)形(xing)(xing)(xing)的(de)(de)允許(xu)值應滿足圖紙上(shang)指(zhi)定的(de)(de)工(gong)(gong)(gong)(gong)(gong)件尺寸，變(bian)(bian)(bian)(bian)(bian)形(xing)(xing)(xing)變(bian)(bian)(bian)(bian)(bian)量應根據前一加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)的(de)(de)尺寸確(que)定。因此(ci)，根據工(gong)(gong)(gong)(gong)(gong)件的(de)(de)變(bian)(bian)(bian)(bian)(bian)形(xing)(xing)(xing)，應在熱(re)(re)(re)處(chu)理(li)之前進行尺寸的(de)(de)預校正，以使熱(re)(re)(re)處(chu)理(li)變(bian)(bian)(bian)(bian)(bian)形(xing)(xing)(xing)在合格范圍內。當熱(re)(re)(re)處(chu)理(li)是中間過程時(shi)，應將熱(re)(re)(re)處(chu)理(li)前的(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)余(yu)量視為加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)余(yu)量和熱(re)(re)(re)處(chu)理(li)變(bian)(bian)(bian)(bian)(bian)形(xing)(xing)(xing)的(de)(de)總和。通常，加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)余(yu)量容(rong)易(yi)確(que)定，并(bing)且由于(yu)許(xu)多影(ying)響因素(su)而使熱(re)(re)(re)處(chu)理(li)更加(jia)(jia)復雜，因此(ci)留有足夠的(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)余(yu)量用于(yu)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)，其余(yu)的(de)(de)可以用作熱(re)(re)(re)處(chu)理(li)容(rong)許(xu)變(bian)(bian)(bian)(bian)(bian)形(xing)(xing)(xing)變(bian)(bian)(bian)(bian)(bian)量。熱(re)(re)(re)處(chu)理(li)后的(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)后，根據工(gong)(gong)(gong)(gong)(gong)件的(de)(de)變(bian)(bian)(bian)(bian)(bian)形(xing)(xing)(xing)規律，采用抗變(bian)(bian)(bian)(bian)(bian)形(xing)(xing)(xing)和收縮端預擴孔，以提高(gao)淬(cui)火后的(de)(de)變(bian)(bian)(bian)(bian)(bian)形(xing)(xing)(xing)合格率。

（3）使用適當(dang)的媒(mei)體

鋼熱處理廠家在確保相(xiang)(xiang)同的(de)(de)硬度要(yao)求的(de)(de)前提(ti)下，嘗試使用油(you)(you)性介(jie)質(zhi)。實驗和實踐證明，在沒有其他條件的(de)(de)前提(ti)下，油(you)(you)性介(jie)質(zhi)的(de)(de)冷卻速度較(jiao)慢，而(er)水(shui)性介(jie)質(zhi)的(de)(de)冷卻速度則相(xiang)(xiang)對(dui)較(jiao)快。而(er)且，與油(you)(you)性介(jie)質(zhi)相(xiang)(xiang)比(bi)，水(shui)溫變化對(dui)水(shui)性介(jie)質(zhi)的(de)(de)冷卻特性影響更(geng)大(da)。在相(xiang)(xiang)同的(de)(de)熱處(chu)理(li)條件下，與水(shui)性介(jie)質(zhi)相(xiang)(xiang)比(bi)，淬(cui)火后油(you)(you)性介(jie)質(zhi)的(de)(de)變形量相(xiang)(xiang)對(dui)較(jiao)小(xiao)。

鋼熱處理廠家可以改善(shan)工件的(de)(de)機(ji)械性能，并提高(gao)工件的(de)(de)強度(du)和(he)(he)(he)硬度(du)，但不(bu)可避免地產(chan)生變形效果。現(xian)階段，我們必須重視中國(guo)熱(re)(re)處(chu)理(li)技術和(he)(he)(he)設(she)備(bei)的(de)(de)改進(jin)，不(bu)斷(duan)學習國(guo)外先進(jin)技術，提高(gao)熱(re)(re)處(chu)理(li)工件的(de)(de)質量和(he)(he)(he)合格(ge)率，為中國(guo)熱(re)(re)處(chu)理(li)行業做出(chu)貢獻。
