鍛造鍛件時退火(huo)的目的和種(zhong)類？

退火是指(zhi)將鍛(duan)件加熱到適當溫度(du)，保持一定時間，然后(hou)級慢(man)冷卻的熱處理(li)工藝。

退火的(de)實質是將(jiang)鋼加熱奧氏(shi)體(ti)(ti)(ti)化后進行珠光體(ti)(ti)(ti)轉(zhuan)變。退火后的(de)組(zu)織，對(dui)(dui)亞共(gong)析(xi)鋼通常是鐵素體(ti)(ti)(ti)+片狀(zhuang)珠光體(ti)(ti)(ti)；而對(dui)(dui)共(gong)析(xi)鋼或過(guo)共(gong)析(xi)鋼則是粒狀(zhuang)珠光體(ti)(ti)(ti)。總之，退火組(zu)織是接衡狀(zhuang)態的(de)組(zu)織。

退火的(de)目(mu)的(de)主要有(you)以(yi)(yi)下幾點：降低(di)鋼(gang)的(de)硬度(du)，提高(gao)塑性，以(yi)(yi)利于(yu)切削加工及冷變形(xing)加工。細化品粒(li)，消除因鑄造、鍛造和(he)焊接(jie)后引(yin)起的(de)組(zu)織缺(que)陷(xian)，均勻鋼(gang)的(de)組(zu)織及成分(fen)，改善鋼(gang)的(de)性能或為(wei)以(yi)(yi)后的(de)熱處理作準備。消除鋼(gang)中的(de)內應力(li)，以(yi)(yi)防(fang)止變形(xing)和(he)開(kai)裂。

常用的退(tui)(tui)(tui)火方法有完(wan)全退(tui)(tui)(tui)火、球(qiu)化退(tui)(tui)(tui)火、去應力退(tui)(tui)(tui)火、再結晶退(tui)(tui)(tui)火和均勻化退(tui)(tui)(tui)火等幾種(zhong)。

上述內(nei)容(rong)，希望能(neng)給(gei)大家帶(dai)來(lai)幫助，如(ru)果還(huan)有其他問題，可以(yi)致電公司，我(wo)們會(hui)為(wei)大家答疑解惑。

軸鍛件有哪(na)些技術要求？

我們所說的(de)鍛(duan)件是一(yi)種利用鍛(duan)壓機械對金屬坯料施加(jia)一(yi)定的(de)壓力，使其產生塑性(xing)變形以獲得(de)具有一(yi)定的(de)機械性(xing)能、一(yi)定形狀(zhuang)以及(ji)尺寸鍛(duan)件的(de)一(yi)種加(jia)工(gong)方(fang)法(fa)，鍛(duan)壓（鍛(duan)造(zao)以及(ji)沖壓）的(de)兩大(da)組(zu)成部(bu)分之(zhi)一(yi)，通過鍛(duan)造(zao)是可以消除金屬在冶煉過程(cheng)中產生的(de)鑄(zhu)態(tai)疏松等的(de)缺陷，優化微(wei)觀組(zu)織結構，同(tong)時(shi)由于(yu)其保存了(le)完整的(de)金屬流線(xian)，軸鍛(duan)件的(de)機械性(xing)能一(yi)般是要優于(yu)同(tong)樣材料的(de)鑄(zhu)件。

以(yi)下內容由本公司為您提供，今天我們來分(fen)享鍛(duan)件加工的內容，希望(wang)對(dui)大家有(you)所(suo)幫助：

鍛(duan)造鍛(duan)件(jian)時(shi)退火的目的和(he)種類？

完全退火(huo)：完全退火(huo)又稱重結晶退火(huo)，它是將鍛(duan)件加熱完全奧(ao)氏體化后(hou)緩慢冷卻，獲得接(jie)衡(heng)狀(zhuang)態組織的熱處理工藝。

完全(quan)退(tui)火(huo)主(zhu)要(yao)用于(yu)亞共(gong)析(xi)(xi)鋼，一般是(shi)中(zhong)(zhong)碳鋼及低、中(zhong)(zhong)碳合金結構鋼的(de)鍛件(jian)、鑄件(jian)及熱軋(ya)型(xing)材(cai)，有時(shi)也(ye)用于(yu)它(ta)們的(de)焊接(jie)構件(jian)。完全(quan)退(tui)火(huo)不(bu)適用于(yu)過共(gong)析(xi)(xi)鋼，因為(wei)過共(gong)析(xi)(xi)鋼完全(quan)退(tui)火(huo)需(xu)加熱到以(yi)上，在緩慢冷卻(que)時(shi)，滲碳體會沿奧氏體晶界析(xi)(xi)出，呈網狀(zhuang)分(fen)布，導致材(cai)料脆性增大，給(gei)熱處理留下隱患。
