（1）使(shi)用合理(li)的(de)夾緊方法和(he)固定裝置

目的均勻(yun)加熱(re)和冷卻工件(jian)(jian)以減(jian)少(shao)不(bu)均勻(yun)的熱(re)應力(li)和不(bu)均勻(yun)的組織應力(li)以減(jian)少(shao)變形。夾緊方(fang)法可(ke)以改(gai)變。圓盤部(bu)件(jian)(jian)垂(chui)直于油面，軸部(bu)件(jian)(jian)垂(chui)直安裝。使用(yong)補償墊(dian)圈(quan)和支(zhi)撐墊(dian)圈(quan)。 ，花鍵(jian)孔部(bu)件(jian)(jian)可(ke)使用(yong)滲碳芯軸，疊加墊(dian)圈(quan)等(deng)。

（2）加工

當熱處(chu)(chu)(chu)(chu)理(li)(li)(li)是工(gong)(gong)(gong)件加工(gong)(gong)(gong)過程的(de)最后一(yi)步(bu)時，熱處(chu)(chu)(chu)(chu)理(li)(li)(li)變(bian)形的(de)允許(xu)值應(ying)(ying)滿足圖紙上指定(ding)的(de)工(gong)(gong)(gong)件尺寸，變(bian)形變(bian)量(liang)(liang)應(ying)(ying)根據前(qian)一(yi)加工(gong)(gong)(gong)的(de)尺寸確定(ding)。因此(ci)，根據工(gong)(gong)(gong)件的(de)變(bian)形，應(ying)(ying)在熱處(chu)(chu)(chu)(chu)理(li)(li)(li)之前(qian)進行尺寸的(de)預校正，以(yi)使熱處(chu)(chu)(chu)(chu)理(li)(li)(li)變(bian)形在合格(ge)范圍內(nei)。當熱處(chu)(chu)(chu)(chu)理(li)(li)(li)是中間過程時，應(ying)(ying)將熱處(chu)(chu)(chu)(chu)理(li)(li)(li)前(qian)的(de)加工(gong)(gong)(gong)余(yu)量(liang)(liang)視為(wei)加工(gong)(gong)(gong)余(yu)量(liang)(liang)和熱處(chu)(chu)(chu)(chu)理(li)(li)(li)變(bian)形的(de)總和。通(tong)常，加工(gong)(gong)(gong)余(yu)量(liang)(liang)容易確定(ding)，并且由于許(xu)多(duo)影響(xiang)因素而使熱處(chu)(chu)(chu)(chu)理(li)(li)(li)更加復(fu)雜(za)，因此(ci)留(liu)有(you)足夠的(de)加工(gong)(gong)(gong)余(yu)量(liang)(liang)用于加工(gong)(gong)(gong)，其余(yu)的(de)可(ke)以(yi)用作熱處(chu)(chu)(chu)(chu)理(li)(li)(li)容許(xu)變(bian)形變(bian)量(liang)(liang)。熱處(chu)(chu)(chu)(chu)理(li)(li)(li)后的(de)加工(gong)(gong)(gong)后，根據工(gong)(gong)(gong)件的(de)變(bian)形規律，采用抗變(bian)形和收縮端預擴孔，以(yi)提(ti)高淬火后的(de)變(bian)形合格(ge)率。

（3）使用適(shi)當(dang)的媒體

鋼熱處理廠家在(zai)確保相(xiang)同(tong)的(de)(de)(de)(de)硬度(du)要求的(de)(de)(de)(de)前提下(xia)，嘗(chang)試使用油性(xing)介(jie)質(zhi)(zhi)。實驗和(he)實踐證明，在(zai)沒有其他條件的(de)(de)(de)(de)前提下(xia)，油性(xing)介(jie)質(zhi)(zhi)的(de)(de)(de)(de)冷卻速度(du)較慢，而水(shui)(shui)性(xing)介(jie)質(zhi)(zhi)的(de)(de)(de)(de)冷卻速度(du)則(ze)相(xiang)對較快。而且，與油性(xing)介(jie)質(zhi)(zhi)相(xiang)比(bi)，水(shui)(shui)溫(wen)變化對水(shui)(shui)性(xing)介(jie)質(zhi)(zhi)的(de)(de)(de)(de)冷卻特性(xing)影響更大(da)。在(zai)相(xiang)同(tong)的(de)(de)(de)(de)熱處(chu)理條件下(xia)，與水(shui)(shui)性(xing)介(jie)質(zhi)(zhi)相(xiang)比(bi)，淬火后(hou)油性(xing)介(jie)質(zhi)(zhi)的(de)(de)(de)(de)變形量相(xiang)對較小。

鋼熱處理廠家可(ke)以改善(shan)工件(jian)(jian)的(de)機(ji)械性(xing)能，并提高工件(jian)(jian)的(de)強(qiang)度(du)和硬(ying)度(du)，但(dan)不(bu)可(ke)避免地產(chan)生變(bian)形(xing)效(xiao)果。現(xian)階段，我們必須重(zhong)視中國(guo)熱處(chu)理技術和設備的(de)改進，不(bu)斷學(xue)習國(guo)外先(xian)進技術，提高熱處(chu)理工件(jian)(jian)的(de)質量(liang)和合格率，為中國(guo)熱處(chu)理行業做出貢獻。
