鍛造鍛件時退火(huo)的種類？

再(zai)結(jie)(jie)晶退(tui)(tui)火：再(zai)結(jie)(jie)晶退(tui)(tui)火又稱為中(zhong)間退(tui)(tui)火。它是指將冷塑性(xing)變形(xing)加(jia)工的鍛件(jian)加(jia)熱(re)到(dao)再(zai)結(jie)(jie)晶溫(wen)度以上，保持適當時(shi)間，通(tong)過再(zai)結(jie)(jie)晶使冷塑性(xing)變形(xing)過程中(zhong)產生的晶體學缺陷基本消失，重新形(xing)成均勻的等軸晶粒，以消除形(xing)變強化(hua)效(xiao)應和殘留應力的退(tui)(tui)火工藝。

再結晶(jing)退火(huo)就是(shi)利用材(cai)料冷塑性變形后(hou)，加(jia)(jia)熱時的再結晶(jing)現象，使被拉長(chang)、壓扁或(huo)破碎(sui)的晶(jing)粒變為(wei)均勻的等軸(zhou)晶(jing)粒，來達到消(xiao)除(chu)加(jia)(jia)工硬(ying)化，恢(hui)復塑變能(neng)力(li)，以(yi)利于進一步變形加(jia)(jia)工的目的。

均勻化退火(huo)：又(you)稱為擴散(san)退火(huo)。以減少鍛件化學成(cheng)分和組織的不均勻性程度為主要(yao)目的，將其加(jia)熱到高溫(wen)并長時間(jian)保持，然后緩慢冷卻(que)的退火(huo)工藝(yi)。

均勻(yun)化(hua)(hua)(hua)退(tui)火的加熱溫度(du)，一(yi)般(ban)選(xuan)在鋼的熔點以(yi)下100~2OO℃，通常(chang)為1050~1150℃，保(bao)溫時間(jian)一(yi)般(ban)為10~15h，以(yi)保(bao)證擴(kuo)散充分(fen)進(jin)行(xing)，達到消除或減少化(hua)(hua)(hua)學成分(fen)或組(zu)織(zhi)不均勻(yun)的目的。由于(yu)均勻(yun)化(hua)(hua)(hua)退(tui)火的加熱溫度(du)高、時間(jian)長，晶粒必(bi)然粗(cu)大。為此，必(bi)須(xu)再進(jin)行(xing)一(yi)次完(wan)全退(tui)火或正火，使(shi)組(zu)織(zhi)重新(xin)細化(hua)(hua)(hua)。

鍛造鍛件(jian)時熱(re)傳遞的基(ji)礎知識

熱(re)傳(chuan)遞(di)(di)是物(wu)(wu)體(ti)相互之間(jian)(jian)或同一(yi)物(wu)(wu)體(ti)內(nei)部熱(re)能(neng)的傳(chuan)遞(di)(di)。溫度(du)差(cha)是熱(re)傳(chuan)遞(di)(di)的必(bi)要條件(jian)。物(wu)(wu)體(ti)間(jian)(jian)或物(wu)(wu)體(ti)內(nei)部各部分(fen)之間(jian)(jian)只要存(cun)在著溫度(du)差(cha)，就(jiu)必(bi)然會產(chan)生熱(re)試的傳(chuan)遞(di)(di)。

熱處理(li)操作(zuo)中的加熱、保(bao)溫和冷卻的過程(cheng)，都(dou)是熱量傳遞的過程(cheng)。為了準確地控制加熱和冷卻的速度，控制保(bao)溫時間(jian)及減少在此過程(cheng)中的熱量損失，有必(bi)要學(xue)習傳熱學(xue)基礎知識。

熱傳遞(di)(di)是一種(zhong)復雜的(de)物理現象。熱傳遞(di)(di)的(de)基本方式有三種(zhong)：傳導、對(dui)流(liu)和輻射。

鍛模是如何維修？

在(zai)設(she)備(bei)上(shang)維修(xiu)。鍛模(mo)在(zai)使(shi)用中(zhong)發現(xian)有局部(bu)損壞時，在(zai)有安(an)全支撐的(de)條件下，可直(zhi)接在(zai)設(she)備(bei)上(shang)修(xiu)理(li)。如(ru)模(mo)膛的(de)凸臺、急轉彎處(chu)、凸圓角和模(mo)口處(chu)極易產生(sheng)堆(dui)塌(ta)。一旦出現(xian)粘模(mo)現(xian)象，就表明有堆(dui)塌(ta)產生(sheng)，應(ying)立即(ji)停(ting)鍛修(xiu)理(li)。一般可用砂輪在(zai)設(she)備(bei)上(shang)就地修(xiu)理(li)。

對大(da)型鍛模(mo)(mo)的(de)較深、較長的(de)裂紋(wen)，可(ke)采用(yong)(yong)機(ji)加(jia)工(gong)清(qing)除裂紋(wen)后， 仍應預熱(re)補焊(han)，補焊(han)中要保持溫(wen)度在400℃左(zuo)右，分區分層焊(han)接，每焊(han)一層后用(yong)(yong)風鎬打實和去除焊(han)渣。如深度較大(da)，離模(mo)(mo)膛和分模(mo)(mo)面50mm以(yi)內的(de)部(bu)分用(yong)(yong)模(mo)(mo)具(ju)鋼(gang)焊(han)條焊(han)接，軸承鍛件(jian)機(ji)加(jia)工(gong)廠家，中間部(bu)分可(ke)用(yong)(yong)一般結構鋼(gang)焊(han)條焊(han)接，焊(han)完后立即入爐(lu)進(jin)行消(xiao)(xiao)除應力退火(huo)，溫(wen)度不(bu)高于鍛模(mo)(mo)熱(re)處理回火(huo)溫(wen)度，所需時間為每30mm用(yong)(yong)lh。消(xiao)(xiao)除應力后用(yong)(yong)機(ji)加(jia)工(gong)方法修復(fu)。

對損(sun)壞特別嚴(yan)重的(de)模具，不能(neng)(neng)用(yong)以上方法修復(fu)時，只(zhi)能(neng)(neng)采用(yong)翻新或報廢。
