（1）使用合(he)理(li)的夾緊(jin)方法和固定裝置(zhi)

目的均(jun)(jun)勻加熱和(he)冷(leng)卻工件(jian)以減(jian)少(shao)不均(jun)(jun)勻的熱應(ying)力和(he)不均(jun)(jun)勻的組織應(ying)力以減(jian)少(shao)變形(xing)。夾緊方法可(ke)以改變。圓(yuan)盤(pan)部件(jian)垂直于油(you)面，軸(zhou)部件(jian)垂直安裝。使用補償墊圈(quan)和(he)支撐墊圈(quan)。 ，花鍵(jian)孔部件(jian)可(ke)使用滲(shen)碳芯(xin)軸(zhou)，疊加墊圈(quan)等(deng)。

（2）加工

當(dang)熱(re)(re)(re)處(chu)(chu)理(li)(li)是工(gong)(gong)(gong)(gong)件加(jia)(jia)工(gong)(gong)(gong)(gong)過程的(de)(de)(de)最后一步(bu)時(shi)，熱(re)(re)(re)處(chu)(chu)理(li)(li)變(bian)(bian)形(xing)(xing)(xing)的(de)(de)(de)允許值應滿足圖紙上指定的(de)(de)(de)工(gong)(gong)(gong)(gong)件尺寸，變(bian)(bian)形(xing)(xing)(xing)變(bian)(bian)量(liang)(liang)(liang)(liang)應根(gen)據(ju)前(qian)一加(jia)(jia)工(gong)(gong)(gong)(gong)的(de)(de)(de)尺寸確定。因(yin)此(ci)(ci)，根(gen)據(ju)工(gong)(gong)(gong)(gong)件的(de)(de)(de)變(bian)(bian)形(xing)(xing)(xing)，應在熱(re)(re)(re)處(chu)(chu)理(li)(li)之前(qian)進行(xing)尺寸的(de)(de)(de)預校正，以(yi)使熱(re)(re)(re)處(chu)(chu)理(li)(li)變(bian)(bian)形(xing)(xing)(xing)在合(he)格范圍內。當(dang)熱(re)(re)(re)處(chu)(chu)理(li)(li)是中間過程時(shi)，應將(jiang)熱(re)(re)(re)處(chu)(chu)理(li)(li)前(qian)的(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)余(yu)量(liang)(liang)(liang)(liang)視為加(jia)(jia)工(gong)(gong)(gong)(gong)余(yu)量(liang)(liang)(liang)(liang)和熱(re)(re)(re)處(chu)(chu)理(li)(li)變(bian)(bian)形(xing)(xing)(xing)的(de)(de)(de)總和。通常，加(jia)(jia)工(gong)(gong)(gong)(gong)余(yu)量(liang)(liang)(liang)(liang)容(rong)易確定，并且由于許多影響因(yin)素而使熱(re)(re)(re)處(chu)(chu)理(li)(li)更(geng)加(jia)(jia)復(fu)雜，因(yin)此(ci)(ci)留有(you)足夠的(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)余(yu)量(liang)(liang)(liang)(liang)用(yong)于加(jia)(jia)工(gong)(gong)(gong)(gong)，其余(yu)的(de)(de)(de)可(ke)以(yi)用(yong)作熱(re)(re)(re)處(chu)(chu)理(li)(li)容(rong)許變(bian)(bian)形(xing)(xing)(xing)變(bian)(bian)量(liang)(liang)(liang)(liang)。熱(re)(re)(re)處(chu)(chu)理(li)(li)后的(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)后，根(gen)據(ju)工(gong)(gong)(gong)(gong)件的(de)(de)(de)變(bian)(bian)形(xing)(xing)(xing)規律，采用(yong)抗變(bian)(bian)形(xing)(xing)(xing)和收縮端預擴孔，以(yi)提高淬火后的(de)(de)(de)變(bian)(bian)形(xing)(xing)(xing)合(he)格率。

（3）使(shi)用適當的媒體

鋼熱處理廠家在(zai)確(que)保相(xiang)(xiang)同(tong)(tong)的硬度(du)要求(qiu)的前(qian)提下，嘗試使(shi)用油(you)性(xing)(xing)(xing)介(jie)質(zhi)(zhi)(zhi)(zhi)(zhi)。實驗和實踐證明，在(zai)沒有其他條件的前(qian)提下，油(you)性(xing)(xing)(xing)介(jie)質(zhi)(zhi)(zhi)(zhi)(zhi)的冷(leng)(leng)卻(que)速度(du)較(jiao)慢(man)，而水(shui)(shui)性(xing)(xing)(xing)介(jie)質(zhi)(zhi)(zhi)(zhi)(zhi)的冷(leng)(leng)卻(que)速度(du)則相(xiang)(xiang)對(dui)較(jiao)快(kuai)。而且，與(yu)(yu)油(you)性(xing)(xing)(xing)介(jie)質(zhi)(zhi)(zhi)(zhi)(zhi)相(xiang)(xiang)比(bi)，水(shui)(shui)溫變(bian)化對(dui)水(shui)(shui)性(xing)(xing)(xing)介(jie)質(zhi)(zhi)(zhi)(zhi)(zhi)的冷(leng)(leng)卻(que)特性(xing)(xing)(xing)影響更大。在(zai)相(xiang)(xiang)同(tong)(tong)的熱處理條件下，與(yu)(yu)水(shui)(shui)性(xing)(xing)(xing)介(jie)質(zhi)(zhi)(zhi)(zhi)(zhi)相(xiang)(xiang)比(bi)，淬火(huo)后(hou)油(you)性(xing)(xing)(xing)介(jie)質(zhi)(zhi)(zhi)(zhi)(zhi)的變(bian)形量相(xiang)(xiang)對(dui)較(jiao)小(xiao)。

鋼熱處理廠家可以改善工件的機械性能，并(bing)提(ti)(ti)高(gao)工件的強度和硬(ying)度，但不可避(bi)免地產生(sheng)變(bian)形效果。現(xian)階段，我們必須重(zhong)視(shi)中(zhong)國(guo)熱處(chu)理技術(shu)和設備的改進，不斷學(xue)習國(guo)外先進技術(shu)，提(ti)(ti)高(gao)熱處(chu)理工件的質量和合格率(lv)，為中(zhong)國(guo)熱處(chu)理行業(ye)做出(chu)貢獻。
