（1）使用合(he)理的夾(jia)緊方法和固定裝置

目的(de)均勻(yun)加熱和(he)冷卻工件(jian)以(yi)減少(shao)不(bu)均勻(yun)的(de)熱應力和(he)不(bu)均勻(yun)的(de)組織應力以(yi)減少(shao)變形(xing)。夾緊方法可(ke)以(yi)改變。圓(yuan)盤部(bu)件(jian)垂直于(yu)油面，軸(zhou)部(bu)件(jian)垂直安裝(zhuang)。使用補償墊(dian)(dian)圈(quan)和(he)支(zhi)撐墊(dian)(dian)圈(quan)。 ，花鍵孔部(bu)件(jian)可(ke)使用滲(shen)碳芯軸(zhou)，疊加墊(dian)(dian)圈(quan)等(deng)。

（2）加工

當熱(re)(re)(re)(re)處(chu)(chu)理(li)(li)(li)(li)是(shi)工(gong)(gong)(gong)(gong)件(jian)加(jia)(jia)工(gong)(gong)(gong)(gong)過(guo)程的(de)(de)(de)(de)最后一步時，熱(re)(re)(re)(re)處(chu)(chu)理(li)(li)(li)(li)變(bian)(bian)(bian)(bian)(bian)形(xing)(xing)的(de)(de)(de)(de)允許值應(ying)滿(man)足(zu)圖(tu)紙上(shang)指定(ding)(ding)的(de)(de)(de)(de)工(gong)(gong)(gong)(gong)件(jian)尺(chi)寸(cun)，變(bian)(bian)(bian)(bian)(bian)形(xing)(xing)變(bian)(bian)(bian)(bian)(bian)量(liang)應(ying)根據前(qian)一加(jia)(jia)工(gong)(gong)(gong)(gong)的(de)(de)(de)(de)尺(chi)寸(cun)確(que)定(ding)(ding)。因(yin)此，根據工(gong)(gong)(gong)(gong)件(jian)的(de)(de)(de)(de)變(bian)(bian)(bian)(bian)(bian)形(xing)(xing)，應(ying)在熱(re)(re)(re)(re)處(chu)(chu)理(li)(li)(li)(li)之(zhi)前(qian)進行尺(chi)寸(cun)的(de)(de)(de)(de)預校(xiao)正，以使熱(re)(re)(re)(re)處(chu)(chu)理(li)(li)(li)(li)變(bian)(bian)(bian)(bian)(bian)形(xing)(xing)在合格范圍(wei)內。當熱(re)(re)(re)(re)處(chu)(chu)理(li)(li)(li)(li)是(shi)中間(jian)過(guo)程時，應(ying)將熱(re)(re)(re)(re)處(chu)(chu)理(li)(li)(li)(li)前(qian)的(de)(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)余量(liang)視為(wei)加(jia)(jia)工(gong)(gong)(gong)(gong)余量(liang)和熱(re)(re)(re)(re)處(chu)(chu)理(li)(li)(li)(li)變(bian)(bian)(bian)(bian)(bian)形(xing)(xing)的(de)(de)(de)(de)總和。通常，加(jia)(jia)工(gong)(gong)(gong)(gong)余量(liang)容易(yi)確(que)定(ding)(ding)，并且由(you)于許多(duo)影響因(yin)素(su)而使熱(re)(re)(re)(re)處(chu)(chu)理(li)(li)(li)(li)更(geng)加(jia)(jia)復雜，因(yin)此留有足(zu)夠的(de)(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)余量(liang)用(yong)于加(jia)(jia)工(gong)(gong)(gong)(gong)，其余的(de)(de)(de)(de)可(ke)以用(yong)作(zuo)熱(re)(re)(re)(re)處(chu)(chu)理(li)(li)(li)(li)容許變(bian)(bian)(bian)(bian)(bian)形(xing)(xing)變(bian)(bian)(bian)(bian)(bian)量(liang)。熱(re)(re)(re)(re)處(chu)(chu)理(li)(li)(li)(li)后的(de)(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)后，根據工(gong)(gong)(gong)(gong)件(jian)的(de)(de)(de)(de)變(bian)(bian)(bian)(bian)(bian)形(xing)(xing)規律(lv)，采用(yong)抗(kang)變(bian)(bian)(bian)(bian)(bian)形(xing)(xing)和收縮(suo)端預擴(kuo)孔，以提(ti)高淬(cui)火后的(de)(de)(de)(de)變(bian)(bian)(bian)(bian)(bian)形(xing)(xing)合格率。

（3）使用適(shi)當的媒(mei)體

鋼熱處理廠家在(zai)確保(bao)相(xiang)同的硬度要(yao)求的前提下，嘗試(shi)使(shi)用(yong)油性(xing)介質。實(shi)驗和實(shi)踐證明(ming)，在(zai)沒有(you)其他條件(jian)的前提下，油性(xing)介質的冷卻速(su)度較慢，而水(shui)(shui)(shui)性(xing)介質的冷卻速(su)度則(ze)相(xiang)對較快。而且(qie)，與(yu)油性(xing)介質相(xiang)比(bi)，水(shui)(shui)(shui)溫(wen)變化對水(shui)(shui)(shui)性(xing)介質的冷卻特性(xing)影響更大。在(zai)相(xiang)同的熱(re)處理條件(jian)下，與(yu)水(shui)(shui)(shui)性(xing)介質相(xiang)比(bi)，淬火后油性(xing)介質的變形量相(xiang)對較小。

鋼熱處理廠家可(ke)以改(gai)(gai)善工(gong)件(jian)的機(ji)械性能，并提高工(gong)件(jian)的強度和(he)(he)硬度，但(dan)不(bu)可(ke)避(bi)免地產生變(bian)形效果。現階(jie)段(duan)，我(wo)們(men)必(bi)須重視中(zhong)(zhong)國熱(re)(re)處理技(ji)術和(he)(he)設備的改(gai)(gai)進(jin)，不(bu)斷學習國外(wai)先進(jin)技(ji)術，提高熱(re)(re)處理工(gong)件(jian)的質量和(he)(he)合(he)格率，為中(zhong)(zhong)國熱(re)(re)處理行業做出貢獻(xian)。
