（1）使(shi)用(yong)合理的夾緊方法和固定(ding)裝置

目的均(jun)勻(yun)加熱和(he)冷卻工件(jian)以減少不均(jun)勻(yun)的熱應力(li)(li)和(he)不均(jun)勻(yun)的組織(zhi)應力(li)(li)以減少變(bian)(bian)形。夾緊方法(fa)可(ke)以改變(bian)(bian)。圓盤(pan)部件(jian)垂(chui)直(zhi)于油面，軸部件(jian)垂(chui)直(zhi)安(an)裝(zhuang)。使用(yong)(yong)補償墊(dian)圈(quan)和(he)支撐墊(dian)圈(quan)。 ，花鍵孔部件(jian)可(ke)使用(yong)(yong)滲碳芯軸，疊加墊(dian)圈(quan)等。

（2）加工

當熱(re)(re)(re)(re)(re)(re)處(chu)(chu)(chu)(chu)理(li)(li)(li)是(shi)工(gong)件加(jia)工(gong)過程的(de)(de)最后(hou)一(yi)步時，熱(re)(re)(re)(re)(re)(re)處(chu)(chu)(chu)(chu)理(li)(li)(li)變(bian)(bian)形(xing)(xing)的(de)(de)允許值應(ying)(ying)滿足圖紙上指(zhi)定的(de)(de)工(gong)件尺寸，變(bian)(bian)形(xing)(xing)變(bian)(bian)量(liang)(liang)應(ying)(ying)根據(ju)(ju)前一(yi)加(jia)工(gong)的(de)(de)尺寸確定。因(yin)此(ci)，根據(ju)(ju)工(gong)件的(de)(de)變(bian)(bian)形(xing)(xing)，應(ying)(ying)在(zai)熱(re)(re)(re)(re)(re)(re)處(chu)(chu)(chu)(chu)理(li)(li)(li)之前進行尺寸的(de)(de)預校正，以(yi)使(shi)熱(re)(re)(re)(re)(re)(re)處(chu)(chu)(chu)(chu)理(li)(li)(li)變(bian)(bian)形(xing)(xing)在(zai)合(he)格范圍(wei)內。當熱(re)(re)(re)(re)(re)(re)處(chu)(chu)(chu)(chu)理(li)(li)(li)是(shi)中間過程時，應(ying)(ying)將熱(re)(re)(re)(re)(re)(re)處(chu)(chu)(chu)(chu)理(li)(li)(li)前的(de)(de)加(jia)工(gong)余(yu)量(liang)(liang)視為(wei)加(jia)工(gong)余(yu)量(liang)(liang)和熱(re)(re)(re)(re)(re)(re)處(chu)(chu)(chu)(chu)理(li)(li)(li)變(bian)(bian)形(xing)(xing)的(de)(de)總和。通(tong)常，加(jia)工(gong)余(yu)量(liang)(liang)容易(yi)確定，并且由于許多影響因(yin)素而使(shi)熱(re)(re)(re)(re)(re)(re)處(chu)(chu)(chu)(chu)理(li)(li)(li)更加(jia)復雜，因(yin)此(ci)留有足夠的(de)(de)加(jia)工(gong)余(yu)量(liang)(liang)用(yong)于加(jia)工(gong)，其余(yu)的(de)(de)可以(yi)用(yong)作熱(re)(re)(re)(re)(re)(re)處(chu)(chu)(chu)(chu)理(li)(li)(li)容許變(bian)(bian)形(xing)(xing)變(bian)(bian)量(liang)(liang)。熱(re)(re)(re)(re)(re)(re)處(chu)(chu)(chu)(chu)理(li)(li)(li)后(hou)的(de)(de)加(jia)工(gong)后(hou)，根據(ju)(ju)工(gong)件的(de)(de)變(bian)(bian)形(xing)(xing)規律，采用(yong)抗變(bian)(bian)形(xing)(xing)和收縮(suo)端預擴(kuo)孔，以(yi)提(ti)高淬火后(hou)的(de)(de)變(bian)(bian)形(xing)(xing)合(he)格率。

（3）使用適當的媒體

鋼熱處理廠家在(zai)(zai)確保(bao)相同的(de)硬度要求的(de)前提下(xia)，嘗(chang)試使用油性(xing)介質(zhi)(zhi)。實驗和實踐(jian)證明，在(zai)(zai)沒有其他條(tiao)件的(de)前提下(xia)，油性(xing)介質(zhi)(zhi)的(de)冷(leng)卻(que)速(su)度較(jiao)慢，而水(shui)(shui)(shui)性(xing)介質(zhi)(zhi)的(de)冷(leng)卻(que)速(su)度則(ze)相對較(jiao)快。而且，與(yu)油性(xing)介質(zhi)(zhi)相比，水(shui)(shui)(shui)溫變(bian)(bian)化對水(shui)(shui)(shui)性(xing)介質(zhi)(zhi)的(de)冷(leng)卻(que)特性(xing)影響更大。在(zai)(zai)相同的(de)熱(re)處(chu)理條(tiao)件下(xia)，與(yu)水(shui)(shui)(shui)性(xing)介質(zhi)(zhi)相比，淬火(huo)后(hou)油性(xing)介質(zhi)(zhi)的(de)變(bian)(bian)形量相對較(jiao)小。

鋼熱處理廠家可以改善工(gong)件(jian)(jian)(jian)的機械(xie)性能，并提(ti)高工(gong)件(jian)(jian)(jian)的強(qiang)度和(he)(he)硬度，但不可避免(mian)地(di)產生變(bian)形(xing)效果。現階(jie)段，我們必(bi)須重(zhong)視(shi)中(zhong)(zhong)國(guo)熱(re)處(chu)理技術和(he)(he)設(she)備的改進(jin)，不斷學習國(guo)外先進(jin)技術，提(ti)高熱(re)處(chu)理工(gong)件(jian)(jian)(jian)的質量和(he)(he)合格率，為中(zhong)(zhong)國(guo)熱(re)處(chu)理行業做(zuo)出貢獻(xian)。
