軸鍛件有哪(na)些(xie)技術要求？

我(wo)們所說的(de)(de)鍛(duan)(duan)(duan)件(jian)是一種利用鍛(duan)(duan)(duan)壓機械對金(jin)屬(shu)坯(pi)料施(shi)加一定(ding)的(de)(de)壓力，使其產(chan)生塑性(xing)變形以(yi)獲得具有一定(ding)的(de)(de)機械性(xing)能、一定(ding)形狀以(yi)及尺(chi)寸鍛(duan)(duan)(duan)件(jian)的(de)(de)一種加工方(fang)法，鍛(duan)(duan)(duan)壓（鍛(duan)(duan)(duan)造(zao)以(yi)及沖壓）的(de)(de)兩大組(zu)成部分之一，通過(guo)鍛(duan)(duan)(duan)造(zao)是可以(yi)消除金(jin)屬(shu)在冶(ye)煉(lian)過(guo)程中產(chan)生的(de)(de)鑄(zhu)態疏松等(deng)的(de)(de)缺陷，優化微(wei)觀組(zu)織結構，同時由于其保存了(le)完整的(de)(de)金(jin)屬(shu)流(liu)線，軸(zhou)鍛(duan)(duan)(duan)件(jian)的(de)(de)機械性(xing)能一般是要優于同樣材料的(de)(de)鑄(zhu)件(jian)。

提高筒(tong)類鍛件表面質量的措施？

筒(tong)類鍛(duan)件(jian)是(shi)壓力容器中重要的(de)(de)組(zu)成部(bu)分(fen)，筒(tong)節質(zhi)量的(de)(de)好(hao)壞(huai)直接關(guan)系到整臺反應器的(de)(de)好(hao)壞(huai)。由(you)于筒(tong)節大部(bu)分(fen)都需(xu)要鐓粗沖孔、芯棒(bang)拔長(chang)、擴孔等工序(xu) ，所(suo)以(yi)在生(sheng)產過程中容易出(chu)現飛邊(bian)、折傷、橢(tuo)圓等質(zhi)量問題而導(dao)致鍛(duan)件(jian)報廢。本(ben)文結(jie)合筒(tong)類鍛(duan)件(jian)的(de)(de)生(sheng)產工序(xu)分(fen)析總(zong)結(jie)了筒(tong)類鍛(duan)件(jian)的(de)(de)幾種質(zhi)量問題，針對這幾種質(zhi)量問題提出(chu)了解決(jue)方案以(yi)及預防措施。

筒(tong)類鍛件的幾種質量問題

通(tong)過長(chang)期的生產跟蹤，筒類鍛件容易出現以下幾種質(zhi)量問題：

(1) 內外(wai)表面出現凹坑(keng)、折(zhe)傷；

(2) 端面長短不齊、壁厚不均勻；

(3) 筒(tong)節端面出現折傷以及(ji)飛(fei)邊(bian)開裂(lie)、飛(fei)邊(bian)折疊(die)進入筒(tong)身內(nei)部(bu)；

(4) 出成品后橢圓(yuan)度較(jiao)大。

鍛造鍛件時退(tui)火的(de)種類？

再(zai)(zai)(zai)結晶退火：再(zai)(zai)(zai)結晶退火又稱為中間(jian)退火。它是指(zhi)將冷塑性(xing)變形(xing)加工的(de)鍛件加熱到再(zai)(zai)(zai)結晶溫度以上，保持適當時間(jian)，通過再(zai)(zai)(zai)結晶使冷塑性(xing)變形(xing)過程中產生的(de)晶體學缺陷基(ji)本消失，重新形(xing)成(cheng)均勻的(de)等軸晶粒，以消除形(xing)變強(qiang)化效(xiao)應(ying)和殘留應(ying)力(li)的(de)退火工藝(yi)。

再(zai)結晶(jing)退火(huo)就(jiu)是利用材(cai)料冷塑性變(bian)形后(hou)，四川鍛件(jian)鍛造(zao)廠家，加(jia)熱時的再(zai)結晶(jing)現象，使被拉長、壓(ya)扁或破碎的晶(jing)粒變(bian)為均勻的等軸晶(jing)粒，來(lai)達到消除加(jia)工硬化，恢(hui)復塑變(bian)能力，以利于進一(yi)步變(bian)形加(jia)工的目的。

均(jun)勻化(hua)退火：又稱為擴散退火。以(yi)減少(shao)鍛(duan)件化(hua)學成(cheng)分(fen)和組織的(de)不均(jun)勻性程度為主(zhu)要目的(de)，將其(qi)加熱到(dao)高溫并長時間保持，然后緩(huan)慢冷卻的(de)退火工藝。

均勻(yun)化(hua)(hua)退(tui)火(huo)(huo)的(de)加熱溫度，一(yi)般(ban)選在鋼的(de)熔點(dian)以(yi)下(xia)100~2OO℃，通常為1050~1150℃，保溫時間一(yi)般(ban)為10~15h，以(yi)保證擴散充分(fen)進行(xing)，達到消除或減少(shao)化(hua)(hua)學(xue)成(cheng)分(fen)或組織不均勻(yun)的(de)目的(de)。由于均勻(yun)化(hua)(hua)退(tui)火(huo)(huo)的(de)加熱溫度高(gao)、時間長，晶粒(li)必(bi)然粗(cu)大(da)。為此，必(bi)須再進行(xing)一(yi)次完全退(tui)火(huo)(huo)或正火(huo)(huo)，使組織重新細化(hua)(hua)。
