（1）使用合理的夾緊方法(fa)和固定(ding)裝置(zhi)

目的均勻(yun)加(jia)熱和冷(leng)卻工(gong)件(jian)(jian)以(yi)減少不均勻(yun)的熱應力(li)和不均勻(yun)的組織應力(li)以(yi)減少變形。夾緊(jin)方法可(ke)以(yi)改變。圓(yuan)盤部件(jian)(jian)垂(chui)(chui)直于油面，軸部件(jian)(jian)垂(chui)(chui)直安裝。使(shi)用補償墊圈(quan)(quan)和支撐(cheng)墊圈(quan)(quan)。 ，花(hua)鍵孔(kong)部件(jian)(jian)可(ke)使(shi)用滲碳芯軸，疊(die)加(jia)墊圈(quan)(quan)等。

（2）加工

當熱(re)處(chu)(chu)理(li)(li)(li)是(shi)工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)過程(cheng)的(de)最后一步(bu)時，熱(re)處(chu)(chu)理(li)(li)(li)變(bian)(bian)(bian)形的(de)允許值應(ying)滿足圖紙(zhi)上指定(ding)的(de)工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)尺(chi)寸，變(bian)(bian)(bian)形變(bian)(bian)(bian)量(liang)應(ying)根據前(qian)(qian)一加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)的(de)尺(chi)寸確(que)定(ding)。因此，根據工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)的(de)變(bian)(bian)(bian)形，應(ying)在熱(re)處(chu)(chu)理(li)(li)(li)之前(qian)(qian)進行尺(chi)寸的(de)預校(xiao)正，以(yi)使(shi)熱(re)處(chu)(chu)理(li)(li)(li)變(bian)(bian)(bian)形在合格(ge)范(fan)圍內(nei)。當熱(re)處(chu)(chu)理(li)(li)(li)是(shi)中間過程(cheng)時，應(ying)將熱(re)處(chu)(chu)理(li)(li)(li)前(qian)(qian)的(de)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)余(yu)量(liang)視(shi)為加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)余(yu)量(liang)和(he)熱(re)處(chu)(chu)理(li)(li)(li)變(bian)(bian)(bian)形的(de)總和(he)。通常，加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)余(yu)量(liang)容易確(que)定(ding)，并且(qie)由于許多影響因素而使(shi)熱(re)處(chu)(chu)理(li)(li)(li)更加(jia)(jia)復雜(za)，因此留有足夠的(de)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)余(yu)量(liang)用(yong)于加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)，其余(yu)的(de)可以(yi)用(yong)作熱(re)處(chu)(chu)理(li)(li)(li)容許變(bian)(bian)(bian)形變(bian)(bian)(bian)量(liang)。熱(re)處(chu)(chu)理(li)(li)(li)后的(de)加(jia)(jia)工(gong)(gong)(gong)(gong)(gong)(gong)后，根據工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)的(de)變(bian)(bian)(bian)形規律，采用(yong)抗(kang)變(bian)(bian)(bian)形和(he)收(shou)縮端預擴孔，以(yi)提(ti)高淬火(huo)后的(de)變(bian)(bian)(bian)形合格(ge)率。

（3）使用適當的(de)媒體

鋼熱處理廠家在(zai)(zai)確保相同(tong)的(de)(de)(de)硬度要求的(de)(de)(de)前提下，嘗試使用油性(xing)(xing)介質(zhi)(zhi)。實(shi)驗和實(shi)踐證明，在(zai)(zai)沒有其(qi)他條(tiao)件(jian)的(de)(de)(de)前提下，油性(xing)(xing)介質(zhi)(zhi)的(de)(de)(de)冷(leng)卻(que)速度較(jiao)慢(man)，而水(shui)性(xing)(xing)介質(zhi)(zhi)的(de)(de)(de)冷(leng)卻(que)速度則相對較(jiao)快(kuai)。而且，與油性(xing)(xing)介質(zhi)(zhi)相比，水(shui)溫變(bian)化(hua)對水(shui)性(xing)(xing)介質(zhi)(zhi)的(de)(de)(de)冷(leng)卻(que)特(te)性(xing)(xing)影響更大。在(zai)(zai)相同(tong)的(de)(de)(de)熱處(chu)理條(tiao)件(jian)下，與水(shui)性(xing)(xing)介質(zhi)(zhi)相比，淬火后(hou)油性(xing)(xing)介質(zhi)(zhi)的(de)(de)(de)變(bian)形量相對較(jiao)小。

鋼熱處理廠家可以改善工件的機械性(xing)能，并(bing)提高(gao)工件的強度和(he)硬(ying)度，但(dan)不可避(bi)免地產生變形效(xiao)果(guo)。現階段，我們必須(xu)重視中國(guo)熱處理(li)技術(shu)和(he)設備的改進(jin)，不斷學習國(guo)外先進(jin)技術(shu)，提高(gao)熱處理(li)工件的質量和(he)合格率，為中國(guo)熱處理(li)行業(ye)做出(chu)貢(gong)獻。
