以下內容由本(ben)公司為您(nin)提供，今天(tian)(tian)我們來(lai)分(fen)享鍛件加工廠的(de)內容，天(tian)(tian)津鍛件加工廠，希望對(dui)大家有(you)所幫助：

鍛造(zao)鍛件時熱傳遞的基礎知識

一、傳(chuan)導傳(chuan)熱 

熱(re)(re)(re)量直(zhi)接由物體(ti)的(de)(de)一部分(fen)傳(chuan)(chuan)(chuan)(chuan)至另一部分(fen)，或由一物體(ti)直(zhi)接傳(chuan)(chuan)(chuan)(chuan)至與(yu)其接觸(chu)的(de)(de)另一物體(ti)，而(er)物體(ti)的(de)(de)質點沒有移(yi)動(dong)（指宏觀的(de)(de)物質移(yi)動(dong)）的(de)(de)傳(chuan)(chuan)(chuan)(chuan)熱(re)(re)(re)現象，稱為傳(chuan)(chuan)(chuan)(chuan)導(dao)傳(chuan)(chuan)(chuan)(chuan)熱(re)(re)(re)。例如，熱(re)(re)(re)處(chu)理爐(lu)中(zhong)(zhong)的(de)(de)熱(re)(re)(re)量由爐(lu)墻(qiang)內表面(mian)直(zhi)接通過爐(lu)墻(qiang)傳(chuan)(chuan)(chuan)(chuan)至爐(lu)墻(qiang)外表面(mian)；工(gong)件(jian)(jian)在(zai)(zai)爐(lu)底板(ban)上加熱(re)(re)(re)，爐(lu)底板(ban)的(de)(de)熱(re)(re)(re)量直(zhi)接傳(chuan)(chuan)(chuan)(chuan)給工(gong)件(jian)(jian)而(er)將工(gong)件(jian)(jian)加熱(re)(re)(re)。在(zai)(zai)這種傳(chuan)(chuan)(chuan)(chuan)熱(re)(re)(re)方(fang)(fang)式中(zhong)(zhong)，爐(lu)墻(qiang)、爐(lu)底板(ban)和(he)工(gong)件(jian)(jian)的(de)(de)質點并沒有移(yi)動(dong)，僅熱(re)(re)(re)量發生了(le)轉(zhuan)移(yi)，成于傳(chuan)(chuan)(chuan)(chuan)導(dao)傳(chuan)(chuan)(chuan)(chuan)熱(re)(re)(re)。 傳(chuan)(chuan)(chuan)(chuan)導(dao)傳(chuan)(chuan)(chuan)(chuan)熱(re)(re)(re)方(fang)(fang)式在(zai)(zai)固(gu)體(ti)、液體(ti)和(he)氣體(ti)中(zhong)(zhong)都存在(zai)(zai)，尤(you)其在(zai)(zai)固(gu)體(ti)中(zhong)(zhong)明顯，而(er)流體(ti)(液體(ti)或氣體(ti)）的(de)(de)傳(chuan)(chuan)(chuan)(chuan)導(dao)能力一般(ban)較弱(ruo)，有的(de)(de)常忽(hu)略不計。

二、對流傳熱

流(liu)體中不同(tong)部分(fen)(fen)的(de)相對(dui)(dui)位(wei)移(yi)，使(shi)不同(tong)部分(fen)(fen)的(de)質點相互混(hun)合，或者流(liu)體質點與(yu)固體表面碰撞而進行(xing)的(de)熱交換現象，稱為對(dui)(dui)流(liu)傳(chuan)(chuan)熱。對(dui)(dui)流(liu)傳(chuan)(chuan)熱只(zhi)有(you)在流(liu)體運(yun)動(dong)(dong)時(shi)才能發(fa)生(sheng)。鹽(yan)浴爐中利用電(dian)磁力使(shi)熔融鹽(yan)液與(yu)工件(jian)相對(dui)(dui)流(liu)動(dong)(dong)、在回火爐中熱風循(xun)環流(liu)經鍛件(jian)表面時(shi)的(de)傳(chuan)(chuan)熱過(guo)程都是對(dui)(dui)流(liu)傳(chuan)(chuan)熱。

山西鍛件(jian)廠鋼的形變熱處理有哪(na)些？

變(bian)形(xing)在相(xiang)變(bian)中(zhong)進行的形(xing)變(bian)熱處理等溫形(xing)變(bian)淬(cui)火(huo)。

通(tong)常于奧氏體(ti)(ti)(ti)發生分解的(de)珠光體(ti)(ti)(ti)或(huo)貝氏體(ti)(ti)(ti)相變過程中進行變形。適用于進行等溫淬火的(de)小型鍛件。

連續冷(leng)卻(que)(que)形變(bian)熱(re)處理：在奧氏(shi)體連續冷(leng)卻(que)(que)轉變(bian)中進行變(bian)形。應用范圍同等溫形變(bian)淬(cui)火。

變(bian)形(xing)在相變(bian)后進行的形(xing)變(bian)熱(re)處理。

珠光體溫形變：將退火鋼(gang)如熱到700~750℃進(jin)行變形，然(ran)后慢(man)速(su)冷卻(que)到600℃左右出爐。適用于軸承毛坯及其(qi)它球化組織要求較高的鍛(duan)件(jian)。

馬氏(shi)體(ti)形變(bian)時(shi)效(xiao)：使低碳鋼淬成(cheng)馬氏(shi)體(ti)（冋火馬氏(shi)沐、貝(bei)氏(shi)體(ti))，在室溫下變(bian)形，然后(hou)進行時(shi)效(xiao)（200℃左右)。適用于制(zhi)造超(chao)高(gao)強(qiang)度中、小鍛件。

如以鍛造變(bian)(bian)(bian)形(xing)(xing)(xing)(xing)溫(wen)度高(gao)(gao)低區分(fen)，上述形(xing)(xing)(xing)(xing)變(bian)(bian)(bian)熱處(chu)(chu)理又可歸納為三類：與(yu)熱鍛相(xiang)(xiang)結含的(de)形(xing)(xing)(xing)(xing)變(bian)(bian)(bian)熱處(chu)(chu)理，如高(gao)(gao)溫(wen)形(xing)(xing)(xing)(xing)變(bian)(bian)(bian)淬(cui)火(huo)(huo)、高(gao)(gao)溫(wen)形(xing)(xing)(xing)(xing)變(bian)(bian)(bian)正火(huo)(huo)、高(gao)(gao)溫(wen)形(xing)(xing)(xing)(xing)變(bian)(bian)(bian)等(deng)溫(wen)淬(cui)火(huo)(huo)、連續冷卻形(xing)(xing)(xing)(xing)變(bian)(bian)(bian)處(chu)(chu)理等(deng)；與(yu)溫(wen)鍛相(xiang)(xiang)結合的(de)形(xing)(xing)(xing)(xing)變(bian)(bian)(bian)熱處(chu)(chu)理，如低溫(wen)形(xing)(xing)(xing)(xing)變(bian)(bian)(bian)淬(cui)火(huo)(huo)、低溫(wen)形(xing)(xing)(xing)(xing)變(bian)(bian)(bian)等(deng)溫(wen)淬(cui)火(huo)(huo)、等(deng)溫(wen)形(xing)(xing)(xing)(xing)變(bian)(bian)(bian)淬(cui)火(huo)(huo)、珠光休(xiu)溫(wen)形(xing)(xing)(xing)(xing)變(bian)(bian)(bian)等(deng)；與(yu)冷鍛相(xiang)(xiang)結合的(de)形(xing)(xing)(xing)(xing)變(bian)(bian)(bian)熱處(chu)(chu)理，如馬氏體(ti)形(xing)(xing)(xing)(xing)變(bian)(bian)(bian)時效(xiao)等(deng)。
