（1）使(shi)用合理的夾緊方法和固定裝置

目的(de)均(jun)(jun)勻加熱(re)和冷卻工(gong)件(jian)以(yi)減少(shao)不均(jun)(jun)勻的(de)熱(re)應力和不均(jun)(jun)勻的(de)組(zu)織應力以(yi)減少(shao)變形(xing)。夾緊(jin)方法(fa)可以(yi)改(gai)變。圓(yuan)盤部件(jian)垂(chui)直(zhi)于(yu)油面，軸部件(jian)垂(chui)直(zhi)安裝。使用補(bu)償墊圈(quan)和支撐墊圈(quan)。 ，花鍵孔部件(jian)可使用滲碳芯軸，疊加墊圈(quan)等(deng)。

（2）加工

當熱(re)(re)處(chu)理(li)(li)(li)(li)是工(gong)(gong)(gong)(gong)件(jian)(jian)加(jia)(jia)工(gong)(gong)(gong)(gong)過(guo)(guo)程(cheng)的最后一(yi)步(bu)時(shi)，熱(re)(re)處(chu)理(li)(li)(li)(li)變(bian)(bian)(bian)形(xing)(xing)的允許(xu)值應滿(man)足(zu)圖紙上(shang)指定的工(gong)(gong)(gong)(gong)件(jian)(jian)尺寸(cun)，變(bian)(bian)(bian)形(xing)(xing)變(bian)(bian)(bian)量(liang)(liang)應根據(ju)前(qian)一(yi)加(jia)(jia)工(gong)(gong)(gong)(gong)的尺寸(cun)確定。因(yin)此，根據(ju)工(gong)(gong)(gong)(gong)件(jian)(jian)的變(bian)(bian)(bian)形(xing)(xing)，應在熱(re)(re)處(chu)理(li)(li)(li)(li)之前(qian)進(jin)行尺寸(cun)的預校(xiao)正(zheng)，以(yi)使熱(re)(re)處(chu)理(li)(li)(li)(li)變(bian)(bian)(bian)形(xing)(xing)在合格(ge)范圍(wei)內。當熱(re)(re)處(chu)理(li)(li)(li)(li)是中(zhong)間(jian)過(guo)(guo)程(cheng)時(shi)，應將熱(re)(re)處(chu)理(li)(li)(li)(li)前(qian)的加(jia)(jia)工(gong)(gong)(gong)(gong)余量(liang)(liang)視(shi)為加(jia)(jia)工(gong)(gong)(gong)(gong)余量(liang)(liang)和(he)熱(re)(re)處(chu)理(li)(li)(li)(li)變(bian)(bian)(bian)形(xing)(xing)的總和(he)。通常，加(jia)(jia)工(gong)(gong)(gong)(gong)余量(liang)(liang)容易確定，并且(qie)由于許(xu)多影響(xiang)因(yin)素而(er)使熱(re)(re)處(chu)理(li)(li)(li)(li)更(geng)加(jia)(jia)復雜，因(yin)此留有足(zu)夠的加(jia)(jia)工(gong)(gong)(gong)(gong)余量(liang)(liang)用(yong)于加(jia)(jia)工(gong)(gong)(gong)(gong)，其余的可以(yi)用(yong)作(zuo)熱(re)(re)處(chu)理(li)(li)(li)(li)容許(xu)變(bian)(bian)(bian)形(xing)(xing)變(bian)(bian)(bian)量(liang)(liang)。熱(re)(re)處(chu)理(li)(li)(li)(li)后的加(jia)(jia)工(gong)(gong)(gong)(gong)后，根據(ju)工(gong)(gong)(gong)(gong)件(jian)(jian)的變(bian)(bian)(bian)形(xing)(xing)規(gui)律(lv)，采用(yong)抗變(bian)(bian)(bian)形(xing)(xing)和(he)收縮端(duan)預擴孔，以(yi)提高淬(cui)火(huo)后的變(bian)(bian)(bian)形(xing)(xing)合格(ge)率。

（3）使用適當的媒體

鋼熱處理廠家在(zai)(zai)確保相同的(de)(de)(de)硬(ying)度要(yao)求(qiu)的(de)(de)(de)前(qian)提下(xia)(xia)，嘗試(shi)使用油性介(jie)(jie)(jie)質(zhi)。實驗(yan)和實踐證(zheng)明(ming)，在(zai)(zai)沒(mei)有其他條(tiao)件(jian)的(de)(de)(de)前(qian)提下(xia)(xia)，油性介(jie)(jie)(jie)質(zhi)的(de)(de)(de)冷(leng)卻(que)(que)速(su)度較(jiao)慢，而(er)水(shui)性介(jie)(jie)(jie)質(zhi)的(de)(de)(de)冷(leng)卻(que)(que)速(su)度則(ze)相對較(jiao)快。而(er)且，與油性介(jie)(jie)(jie)質(zhi)相比(bi)，水(shui)溫變化(hua)對水(shui)性介(jie)(jie)(jie)質(zhi)的(de)(de)(de)冷(leng)卻(que)(que)特性影響更大。在(zai)(zai)相同的(de)(de)(de)熱處理(li)條(tiao)件(jian)下(xia)(xia)，與水(shui)性介(jie)(jie)(jie)質(zhi)相比(bi)，淬(cui)火后油性介(jie)(jie)(jie)質(zhi)的(de)(de)(de)變形量相對較(jiao)小(xiao)。

鋼熱處理廠家可(ke)以(yi)改善工(gong)件的機械性能，并提高工(gong)件的強度(du)(du)和(he)硬度(du)(du)，但不(bu)可(ke)避免(mian)地產生變形效果(guo)。現階(jie)段，我們必須(xu)重視中國(guo)熱處(chu)(chu)理技術和(he)設備的改進(jin)，不(bu)斷學習國(guo)外先進(jin)技術，提高熱處(chu)(chu)理工(gong)件的質(zhi)量和(he)合格(ge)率，為中國(guo)熱處(chu)(chu)理行(xing)業做(zuo)出(chu)貢獻。
