鍛造鍛件時熱(re)傳(chuan)遞的基礎知識

輻射傳熱

由(you)鍛件(jian)表面直接向(xiang)外界發射(she)(she)(she)可(ke)見(jian)(jian)的(de)(de)(de)和不可(ke)見(jian)(jian)的(de)(de)(de)射(she)(she)(she)線，在(zai)空間(jian)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)熱能(neng)的(de)(de)(de)現象(xiang)稱為輻射(she)(she)(she)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)熱。輻射(she)(she)(she)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)熱與傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)導傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)熱、對流傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)熱是(shi)有本質(zhi)(zhi)區別的(de)(de)(de)，它在(zai)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)熱能(neng)的(de)(de)(de)過程(cheng)中(zhong)，不需要相互接觸(chu)，也無需質(zhi)(zhi)點的(de)(de)(de)移動，是(shi)一(yi)種非接觸(chu)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)熱能(neng)的(de)(de)(de)方式，即使在(zai)真空中(zhong)，輻射(she)(she)(she)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)熱也照常能(neng)進行。太(tai)陽(yang)通過茫茫宇宙空間(jian)向(xiang)地球傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)熱量(liang)，我(wo)們能(neng)感覺(jue)到(dao)燒紅工件(jian)所(suo)發出的(de)(de)(de)熱量(liang)，都是(shi)輻射(she)(she)(she)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)熱的(de)(de)(de)典型實例。輻射(she)(she)(she)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)熱的(de)(de)(de)另一(yi)特點是(shi)在(zai)能(neng)量(liang)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)的(de)(de)(de)過程(cheng)中(zhong)，伴(ban)隨著(zhu)能(neng)量(liang)形式的(de)(de)(de)變(bian)化。

例如，太陽內部熱核反應產生巨(ju)大(da)的熱能(neng)，部分熱能(neng)轉變成輻射能(neng)，以電磁波(bo)的形式(shi)向外發(fa)射，而地球吸收(shou)部分輻射能(neng)以后，又轉化成熱能(neng)。

任何物(wu)(wu)體(ti)(ti)(ti)(ti)都不(bu)斷地向四周著輻(fu)(fu)射(she)(she)能，同時它(ta)們也吸收、反射(she)(she)別的(de)物(wu)(wu)體(ti)(ti)(ti)(ti)投(tou)來(lai)的(de)輻(fu)(fu)射(she)(she)能。兩個物(wu)(wu)體(ti)(ti)(ti)(ti)之間(jian)的(de)相互輻(fu)(fu)射(she)(she)，必然引起熱(re)(re)量從溫度較高的(de)物(wu)(wu)體(ti)(ti)(ti)(ti)向溫度較低的(de)物(wu)(wu)體(ti)(ti)(ti)(ti)轉(zhuan)移。輻(fu)(fu)射(she)(she)傳熱(re)(re)在中、高溫熱(re)(re)處理爐的(de)熱(re)(re)交換(huan)中起主要(yao)作用(yong)。

山(shan)西(xi)鍛件廠鋼的(de)形(xing)變(bian)熱處理有哪些？

變(bian)(bian)形(xing)在相變(bian)(bian)中進行的形(xing)變(bian)(bian)熱(re)處理等(deng)溫形(xing)變(bian)(bian)淬火。

通(tong)常于奧氏(shi)體(ti)發生分(fen)解的珠光體(ti)或(huo)貝氏(shi)體(ti)相變過(guo)程中進(jin)行(xing)變形(xing)。適(shi)用(yong)于進(jin)行(xing)等溫淬(cui)火(huo)的小型鍛件。

連續(xu)冷卻形變(bian)熱(re)處(chu)理：在(zai)奧氏體連續(xu)冷卻轉(zhuan)變(bian)中進行變(bian)形。應用范圍(wei)同等溫形變(bian)淬(cui)火。

變(bian)形在相變(bian)后進行(xing)的形變(bian)熱處理。

珠光體溫形(xing)(xing)變：將退火鋼如熱到700~750℃進行變形(xing)(xing)，然后慢速冷(leng)卻到600℃左右出(chu)爐(lu)。適用(yong)于軸承毛坯及(ji)其它球化組織(zhi)要求較(jiao)高的鍛(duan)件。

馬氏(shi)(shi)體形(xing)變時效：使低碳鋼(gang)淬成馬氏(shi)(shi)體（冋火(huo)馬氏(shi)(shi)沐、貝氏(shi)(shi)體)，在室溫下變形(xing)，然(ran)后進(jin)行時效（200℃左右)。適用于制(zhi)造超高強度(du)中(zhong)、小鍛件。

如(ru)以鍛(duan)(duan)造變(bian)形(xing)(xing)溫(wen)(wen)度高低(di)區分，上述形(xing)(xing)變(bian)熱處(chu)(chu)理(li)(li)又(you)可歸納為(wei)三類：與熱鍛(duan)(duan)相結(jie)含的形(xing)(xing)變(bian)熱處(chu)(chu)理(li)(li)，如(ru)高溫(wen)(wen)形(xing)(xing)變(bian)淬火、高溫(wen)(wen)形(xing)(xing)變(bian)正(zheng)火、高溫(wen)(wen)形(xing)(xing)變(bian)等溫(wen)(wen)淬火、連續冷卻形(xing)(xing)變(bian)處(chu)(chu)理(li)(li)等；與溫(wen)(wen)鍛(duan)(duan)相結(jie)合的形(xing)(xing)變(bian)熱處(chu)(chu)理(li)(li)，如(ru)低(di)溫(wen)(wen)形(xing)(xing)變(bian)淬火、低(di)溫(wen)(wen)形(xing)(xing)變(bian)等溫(wen)(wen)淬火、等溫(wen)(wen)形(xing)(xing)變(bian)淬火、珠光休溫(wen)(wen)形(xing)(xing)變(bian)等；與冷鍛(duan)(duan)相結(jie)合的形(xing)(xing)變(bian)熱處(chu)(chu)理(li)(li)，如(ru)馬氏體形(xing)(xing)變(bian)時效等。

不(bu)銹鋼鍛件冷成型加(jia)工常見問題及處理措(cuo)施(shi)

①因待成型(xing)加(jia)工(gong)(gong)坯料(liao)(liao)表面存在(zai)臟污、劃傷(shang)(shang)、凹坑、麻點或重皮等(deng)缺陷(xian)，在(zai)冷加(jia)工(gong)(gong)成型(xing)過程中，這些缺陷(xian)隨著坯料(liao)(liao)的(de)(de)加(jia)工(gong)(gong)變(bian)形而被(bei)放大，直接導致鍛件(jian)臟污、銹(xiu)蝕、模具(ju)劃傷(shang)(shang)、產(chan)品局部開裂等(deng)現象，大大降低(di)成品率。因此，在(zai)成型(xing)加(jia)工(gong)(gong)之前，首(shou)先要仔細檢查坯料(liao)(liao)的(de)(de)表面狀況，S31603鍛件(jian)定制廠家(jia)，保證其(qi)干(gan)凈清潔、無表面缺陷(xian)后(hou)，再進行加(jia)工(gong)(gong)生產(chan)。

②因成型模(mo)具、工(gong)(gong)作平臺臟(zang)污，其表(biao)面(mian)所黏附的金屬(shu)碎屑未能(neng)及時清除(chu)，而(er)導致加(jia)工(gong)(gong)后工(gong)(gong)件表(biao)面(mian)臟(zang)污、銹(xiu)蝕及表(biao)面(mian)出現凹坑、劃傷(shang)現象(xiang)。為避免(mian)這種現象(xiang)，要定期(qi)對加(jia)工(gong)(gong)模(mo)具進行修磨和(he)清理，保(bao)證其工(gong)(gong)作面(mian)的光潔無瑕，同時還(huan)要保(bao)持(chi)加(jia)工(gong)(gong)設備及加(jia)工(gong)(gong)車間的整潔。
