（1）使用合(he)理的夾緊方法和(he)固定(ding)裝置

目(mu)的(de)均勻加熱(re)和(he)冷卻工件以減少不均勻的(de)熱(re)應力和(he)不均勻的(de)組織應力以減少變(bian)形。夾緊方法可以改變(bian)。圓(yuan)盤(pan)部(bu)件垂(chui)直于油面，軸(zhou)部(bu)件垂(chui)直安裝(zhuang)。使用(yong)補償墊(dian)(dian)圈和(he)支撐墊(dian)(dian)圈。 ，花鍵孔部(bu)件可使用(yong)滲碳(tan)芯(xin)軸(zhou)，疊加墊(dian)(dian)圈等。

（2）加工

當熱(re)(re)處(chu)(chu)(chu)理(li)是工(gong)(gong)(gong)(gong)件加工(gong)(gong)(gong)(gong)過(guo)程的(de)(de)最后一步時，熱(re)(re)處(chu)(chu)(chu)理(li)變形(xing)(xing)(xing)的(de)(de)允許值應滿足圖(tu)紙上(shang)指定的(de)(de)工(gong)(gong)(gong)(gong)件尺寸，變形(xing)(xing)(xing)變量應根(gen)據前(qian)(qian)一加工(gong)(gong)(gong)(gong)的(de)(de)尺寸確定。因(yin)此(ci)，根(gen)據工(gong)(gong)(gong)(gong)件的(de)(de)變形(xing)(xing)(xing)，應在熱(re)(re)處(chu)(chu)(chu)理(li)之前(qian)(qian)進行尺寸的(de)(de)預校(xiao)正，以(yi)使熱(re)(re)處(chu)(chu)(chu)理(li)變形(xing)(xing)(xing)在合格范圍內(nei)。當熱(re)(re)處(chu)(chu)(chu)理(li)是中(zhong)間過(guo)程時，應將熱(re)(re)處(chu)(chu)(chu)理(li)前(qian)(qian)的(de)(de)加工(gong)(gong)(gong)(gong)余(yu)(yu)量視為加工(gong)(gong)(gong)(gong)余(yu)(yu)量和熱(re)(re)處(chu)(chu)(chu)理(li)變形(xing)(xing)(xing)的(de)(de)總和。通常，加工(gong)(gong)(gong)(gong)余(yu)(yu)量容(rong)易確定，并且由(you)于許多影(ying)響因(yin)素而使熱(re)(re)處(chu)(chu)(chu)理(li)更(geng)加復雜，因(yin)此(ci)留有足夠的(de)(de)加工(gong)(gong)(gong)(gong)余(yu)(yu)量用(yong)于加工(gong)(gong)(gong)(gong)，其余(yu)(yu)的(de)(de)可以(yi)用(yong)作熱(re)(re)處(chu)(chu)(chu)理(li)容(rong)許變形(xing)(xing)(xing)變量。熱(re)(re)處(chu)(chu)(chu)理(li)后的(de)(de)加工(gong)(gong)(gong)(gong)后，根(gen)據工(gong)(gong)(gong)(gong)件的(de)(de)變形(xing)(xing)(xing)規律，采用(yong)抗(kang)變形(xing)(xing)(xing)和收縮端預擴孔，以(yi)提高淬火后的(de)(de)變形(xing)(xing)(xing)合格率(lv)。

（3）使(shi)用(yong)適當的媒體

鋼熱處理廠家在(zai)(zai)確保相同的(de)硬度要求的(de)前提下(xia)，嘗試使用油性(xing)(xing)介(jie)(jie)質(zhi)(zhi)(zhi)(zhi)(zhi)。實(shi)驗和實(shi)踐證明，在(zai)(zai)沒有其他條件(jian)的(de)前提下(xia)，油性(xing)(xing)介(jie)(jie)質(zhi)(zhi)(zhi)(zhi)(zhi)的(de)冷(leng)卻速(su)度較慢，而水性(xing)(xing)介(jie)(jie)質(zhi)(zhi)(zhi)(zhi)(zhi)的(de)冷(leng)卻速(su)度則(ze)相對較快(kuai)。而且，與油性(xing)(xing)介(jie)(jie)質(zhi)(zhi)(zhi)(zhi)(zhi)相比(bi)，水溫(wen)變(bian)化對水性(xing)(xing)介(jie)(jie)質(zhi)(zhi)(zhi)(zhi)(zhi)的(de)冷(leng)卻特(te)性(xing)(xing)影響更大。在(zai)(zai)相同的(de)熱處理條件(jian)下(xia)，與水性(xing)(xing)介(jie)(jie)質(zhi)(zhi)(zhi)(zhi)(zhi)相比(bi)，淬火(huo)后油性(xing)(xing)介(jie)(jie)質(zhi)(zhi)(zhi)(zhi)(zhi)的(de)變(bian)形量相對較小。

鋼熱處理廠家可以改善工件(jian)的機械(xie)性能(neng)，并提高(gao)工件(jian)的強度和(he)(he)硬度，但不(bu)(bu)可避免地產生變形效果(guo)。現階段，我們必須重視中國熱處(chu)(chu)理(li)技(ji)術(shu)和(he)(he)設備的改進，不(bu)(bu)斷學習國外先進技(ji)術(shu)，提高(gao)熱處(chu)(chu)理(li)工件(jian)的質量和(he)(he)合格(ge)率，為中國熱處(chu)(chu)理(li)行(xing)業做(zuo)出貢(gong)獻。
