（1）使用合理的夾緊方法和固定裝置

目的(de)均勻加(jia)熱(re)和冷卻工件以減少不均勻的(de)熱(re)應力和不均勻的(de)組織應力以減少變形。夾緊方法可以改(gai)變。圓盤部件垂直于油面，軸(zhou)部件垂直安裝。使用補(bu)償墊(dian)(dian)圈(quan)和支撐(cheng)墊(dian)(dian)圈(quan)。 ，花鍵孔部件可使用滲碳芯軸(zhou)，疊加(jia)墊(dian)(dian)圈(quan)等。

（2）加工

當熱(re)(re)(re)(re)(re)處(chu)(chu)(chu)理(li)(li)(li)是(shi)工(gong)(gong)(gong)(gong)件加(jia)(jia)工(gong)(gong)(gong)(gong)過程(cheng)的(de)最后一(yi)(yi)步時(shi)，熱(re)(re)(re)(re)(re)處(chu)(chu)(chu)理(li)(li)(li)變(bian)形(xing)的(de)允許(xu)(xu)值應(ying)(ying)滿足圖紙上指定的(de)工(gong)(gong)(gong)(gong)件尺寸(cun)，變(bian)形(xing)變(bian)量(liang)(liang)(liang)應(ying)(ying)根據(ju)前(qian)一(yi)(yi)加(jia)(jia)工(gong)(gong)(gong)(gong)的(de)尺寸(cun)確(que)定。因(yin)此，根據(ju)工(gong)(gong)(gong)(gong)件的(de)變(bian)形(xing)，應(ying)(ying)在(zai)熱(re)(re)(re)(re)(re)處(chu)(chu)(chu)理(li)(li)(li)之前(qian)進行尺寸(cun)的(de)預(yu)校(xiao)正，以使熱(re)(re)(re)(re)(re)處(chu)(chu)(chu)理(li)(li)(li)變(bian)形(xing)在(zai)合(he)格范圍內。當熱(re)(re)(re)(re)(re)處(chu)(chu)(chu)理(li)(li)(li)是(shi)中(zhong)間過程(cheng)時(shi)，應(ying)(ying)將熱(re)(re)(re)(re)(re)處(chu)(chu)(chu)理(li)(li)(li)前(qian)的(de)加(jia)(jia)工(gong)(gong)(gong)(gong)余(yu)(yu)量(liang)(liang)(liang)視為加(jia)(jia)工(gong)(gong)(gong)(gong)余(yu)(yu)量(liang)(liang)(liang)和熱(re)(re)(re)(re)(re)處(chu)(chu)(chu)理(li)(li)(li)變(bian)形(xing)的(de)總和。通常，加(jia)(jia)工(gong)(gong)(gong)(gong)余(yu)(yu)量(liang)(liang)(liang)容易確(que)定，并且由于許(xu)(xu)多影(ying)響因(yin)素而使熱(re)(re)(re)(re)(re)處(chu)(chu)(chu)理(li)(li)(li)更加(jia)(jia)復雜，因(yin)此留有足夠的(de)加(jia)(jia)工(gong)(gong)(gong)(gong)余(yu)(yu)量(liang)(liang)(liang)用于加(jia)(jia)工(gong)(gong)(gong)(gong)，其余(yu)(yu)的(de)可以用作(zuo)熱(re)(re)(re)(re)(re)處(chu)(chu)(chu)理(li)(li)(li)容許(xu)(xu)變(bian)形(xing)變(bian)量(liang)(liang)(liang)。熱(re)(re)(re)(re)(re)處(chu)(chu)(chu)理(li)(li)(li)后的(de)加(jia)(jia)工(gong)(gong)(gong)(gong)后，根據(ju)工(gong)(gong)(gong)(gong)件的(de)變(bian)形(xing)規律，采用抗變(bian)形(xing)和收縮端預(yu)擴孔，以提高淬火后的(de)變(bian)形(xing)合(he)格率(lv)。

（3）使(shi)用(yong)適當的媒體

鋼熱處理廠家在確保相(xiang)同的(de)硬度要求的(de)前(qian)提下，嘗(chang)試使用油(you)性(xing)(xing)介質。實驗和實踐證明，在沒有(you)其(qi)他條件的(de)前(qian)提下，油(you)性(xing)(xing)介質的(de)冷卻速度較(jiao)慢(man)，而水(shui)性(xing)(xing)介質的(de)冷卻速度則相(xiang)對(dui)較(jiao)快。而且，與油(you)性(xing)(xing)介質相(xiang)比(bi)，水(shui)溫(wen)變化對(dui)水(shui)性(xing)(xing)介質的(de)冷卻特性(xing)(xing)影響更大。在相(xiang)同的(de)熱處理條件下，與水(shui)性(xing)(xing)介質相(xiang)比(bi)，淬(cui)火后油(you)性(xing)(xing)介質的(de)變形(xing)量相(xiang)對(dui)較(jiao)小。

鋼熱處理廠家可以(yi)改善工(gong)件的(de)機械性(xing)能(neng)，并(bing)提高工(gong)件的(de)強度(du)和(he)硬度(du)，但不可避(bi)免地(di)產生變形效果。現階段(duan)，我們必須重視(shi)中國(guo)熱處(chu)理(li)技術(shu)(shu)和(he)設(she)備(bei)的(de)改進(jin)，不斷學習國(guo)外(wai)先進(jin)技術(shu)(shu)，提高熱處(chu)理(li)工(gong)件的(de)質量(liang)和(he)合格(ge)率，為中國(guo)熱處(chu)理(li)行業做出貢獻。
