（1）使用合理(li)的夾緊方法和固定裝(zhuang)置

目的均(jun)勻加(jia)熱和冷卻工件(jian)以減(jian)少不(bu)均(jun)勻的熱應力和不(bu)均(jun)勻的組織應力以減(jian)少變(bian)形。夾(jia)緊方法可(ke)以改變(bian)。圓盤部件(jian)垂直于(yu)油面，軸(zhou)部件(jian)垂直安裝。使(shi)用補償墊(dian)圈和支(zhi)撐墊(dian)圈。 ，花鍵孔(kong)部件(jian)可(ke)使(shi)用滲碳芯軸(zhou)，疊加(jia)墊(dian)圈等。

（2）加工

當熱(re)(re)(re)處(chu)理(li)(li)(li)是工(gong)(gong)件加(jia)(jia)工(gong)(gong)過程的(de)(de)最后(hou)(hou)一步時，熱(re)(re)(re)處(chu)理(li)(li)(li)變(bian)(bian)(bian)(bian)形的(de)(de)允許值應(ying)(ying)(ying)滿足圖紙上指定(ding)的(de)(de)工(gong)(gong)件尺(chi)寸(cun)(cun)，變(bian)(bian)(bian)(bian)形變(bian)(bian)(bian)(bian)量應(ying)(ying)(ying)根(gen)據前一加(jia)(jia)工(gong)(gong)的(de)(de)尺(chi)寸(cun)(cun)確(que)定(ding)。因此(ci)，根(gen)據工(gong)(gong)件的(de)(de)變(bian)(bian)(bian)(bian)形，應(ying)(ying)(ying)在熱(re)(re)(re)處(chu)理(li)(li)(li)之(zhi)前進行(xing)尺(chi)寸(cun)(cun)的(de)(de)預校正，以使(shi)(shi)熱(re)(re)(re)處(chu)理(li)(li)(li)變(bian)(bian)(bian)(bian)形在合格(ge)范圍(wei)內。當熱(re)(re)(re)處(chu)理(li)(li)(li)是中間(jian)過程時，應(ying)(ying)(ying)將熱(re)(re)(re)處(chu)理(li)(li)(li)前的(de)(de)加(jia)(jia)工(gong)(gong)余(yu)量視為(wei)加(jia)(jia)工(gong)(gong)余(yu)量和熱(re)(re)(re)處(chu)理(li)(li)(li)變(bian)(bian)(bian)(bian)形的(de)(de)總和。通常，加(jia)(jia)工(gong)(gong)余(yu)量容易確(que)定(ding)，并且由于許多影響因素而使(shi)(shi)熱(re)(re)(re)處(chu)理(li)(li)(li)更加(jia)(jia)復雜，因此(ci)留有足夠的(de)(de)加(jia)(jia)工(gong)(gong)余(yu)量用(yong)于加(jia)(jia)工(gong)(gong)，其(qi)余(yu)的(de)(de)可(ke)以用(yong)作熱(re)(re)(re)處(chu)理(li)(li)(li)容許變(bian)(bian)(bian)(bian)形變(bian)(bian)(bian)(bian)量。熱(re)(re)(re)處(chu)理(li)(li)(li)后(hou)(hou)的(de)(de)加(jia)(jia)工(gong)(gong)后(hou)(hou)，根(gen)據工(gong)(gong)件的(de)(de)變(bian)(bian)(bian)(bian)形規律(lv)，采用(yong)抗變(bian)(bian)(bian)(bian)形和收縮端(duan)預擴孔，以提(ti)高淬(cui)火后(hou)(hou)的(de)(de)變(bian)(bian)(bian)(bian)形合格(ge)率。

（3）使用適當的媒體

鋼熱處理廠家在確保相(xiang)(xiang)同的(de)(de)硬度(du)要求的(de)(de)前(qian)提下(xia)，嘗試使(shi)用油性介(jie)質(zhi)(zhi)(zhi)。實(shi)驗和實(shi)踐證(zheng)明，在沒有其他條件的(de)(de)前(qian)提下(xia)，油性介(jie)質(zhi)(zhi)(zhi)的(de)(de)冷(leng)卻(que)速度(du)較慢，而(er)水(shui)(shui)性介(jie)質(zhi)(zhi)(zhi)的(de)(de)冷(leng)卻(que)速度(du)則相(xiang)(xiang)對(dui)較快。而(er)且，與(yu)油性介(jie)質(zhi)(zhi)(zhi)相(xiang)(xiang)比，水(shui)(shui)溫變(bian)化對(dui)水(shui)(shui)性介(jie)質(zhi)(zhi)(zhi)的(de)(de)冷(leng)卻(que)特性影響(xiang)更(geng)大。在相(xiang)(xiang)同的(de)(de)熱處理(li)條件下(xia)，與(yu)水(shui)(shui)性介(jie)質(zhi)(zhi)(zhi)相(xiang)(xiang)比，淬火后油性介(jie)質(zhi)(zhi)(zhi)的(de)(de)變(bian)形量相(xiang)(xiang)對(dui)較小。

鋼熱處理廠家可(ke)(ke)以(yi)改(gai)善工(gong)件的機械性能，并提高工(gong)件的強度(du)和硬度(du)，但(dan)不(bu)可(ke)(ke)避免地產生變形效果(guo)。現(xian)階段，我(wo)們必須重視中國(guo)熱處(chu)(chu)理(li)技術(shu)和設備的改(gai)進，不(bu)斷學習國(guo)外(wai)先進技術(shu)，提高熱處(chu)(chu)理(li)工(gong)件的質(zhi)量和合格率(lv)，為中國(guo)熱處(chu)(chu)理(li)行(xing)業做(zuo)出貢獻。
