鍛(duan)造鍛(duan)件時熱傳遞的(de)基礎知識(shi)

輻射傳熱

由(you)鍛件表面(mian)直接向外界(jie)發射(she)(she)可見的和不可見的射(she)(she)線，在(zai)空(kong)間傳(chuan)(chuan)(chuan)(chuan)遞(di)熱(re)(re)(re)能(neng)的現象(xiang)稱為(wei)輻(fu)射(she)(she)傳(chuan)(chuan)(chuan)(chuan)熱(re)(re)(re)。輻(fu)射(she)(she)傳(chuan)(chuan)(chuan)(chuan)熱(re)(re)(re)與(yu)傳(chuan)(chuan)(chuan)(chuan)導傳(chuan)(chuan)(chuan)(chuan)熱(re)(re)(re)、對流傳(chuan)(chuan)(chuan)(chuan)熱(re)(re)(re)是(shi)(shi)有(you)本質區別的，它在(zai)傳(chuan)(chuan)(chuan)(chuan)遞(di)熱(re)(re)(re)能(neng)的過(guo)程(cheng)中，不需要相互(hu)接觸，也無(wu)需質點(dian)的移動，是(shi)(shi)一種非接觸傳(chuan)(chuan)(chuan)(chuan)遞(di)熱(re)(re)(re)能(neng)的方式(shi)，即使在(zai)真空(kong)中，輻(fu)射(she)(she)傳(chuan)(chuan)(chuan)(chuan)熱(re)(re)(re)也照常能(neng)進行(xing)。太陽通(tong)過(guo)茫(mang)(mang)茫(mang)(mang)宇宙空(kong)間向地球傳(chuan)(chuan)(chuan)(chuan)遞(di)熱(re)(re)(re)量(liang)，我們能(neng)感覺到燒紅工件所(suo)發出的熱(re)(re)(re)量(liang)，都是(shi)(shi)輻(fu)射(she)(she)傳(chuan)(chuan)(chuan)(chuan)熱(re)(re)(re)的典型實例。輻(fu)射(she)(she)傳(chuan)(chuan)(chuan)(chuan)熱(re)(re)(re)的另一特(te)點(dian)是(shi)(shi)在(zai)能(neng)量(liang)傳(chuan)(chuan)(chuan)(chuan)遞(di)的過(guo)程(cheng)中，伴隨著能(neng)量(liang)形(xing)式(shi)的變化。

例如，太陽(yang)內部(bu)(bu)熱(re)核反(fan)應產生巨(ju)大的(de)熱(re)能(neng)，部(bu)(bu)分熱(re)能(neng)轉變成輻(fu)射能(neng)，以電(dian)磁波的(de)形(xing)式向外發射，而地球吸收部(bu)(bu)分輻(fu)射能(neng)以后，又轉化成熱(re)能(neng)。

任何物(wu)(wu)體(ti)都不斷地向四周(zhou)著輻(fu)(fu)射(she)能(neng)，同時(shi)它們也(ye)吸(xi)收、反射(she)別(bie)的物(wu)(wu)體(ti)投(tou)來的輻(fu)(fu)射(she)能(neng)。兩個物(wu)(wu)體(ti)之(zhi)間的相(xiang)互(hu)輻(fu)(fu)射(she)，必然引(yin)起熱量從溫(wen)度較高的物(wu)(wu)體(ti)向溫(wen)度較低的物(wu)(wu)體(ti)轉移(yi)。輻(fu)(fu)射(she)傳熱在中(zhong)、高溫(wen)熱處理爐(lu)的熱交換(huan)中(zhong)起主(zhu)要(yao)作用(yong)。

大(da)家好本期(qi)小編給大(da)家帶來新的內容，希望(wang)對(dui)大(da)家有所幫助(zhu)：筒(tong)類鍛件(jian)加工

鋼鍛(duan)件在鍛(duan)造車(che)間內(nei)進(jin)(jin)行熱處理的(de)主要目的(de)是改善鍛(duan)件的(de)切削性(xing)能(neng)；鍛(duan)件加工后的(de)終熱處理則(ze)在熱處理車(che)間進(jin)(jin)行。對于有色金屬鍛(duan)件的(de)熱處理，大(da)部分是由鍛(duan)造車(che)間來完成的(de)。

保(bao)證熱(re)處理質量的(de)(de)(de)(de)一個重(zhong)要(yao)環節是(shi)(shi)鍛件(jian)加熱(re)溫(wen)(wen)度(du)(du)的(de)(de)(de)(de)均(jun)勻性。對于大多數低合(he)金(jin)鋼(gang)的(de)(de)(de)(de)淬(cui)火來(lai)說，奧氏(shi)體(ti)化(hua)的(de)(de)(de)(de)溫(wen)(wen)度(du)(du)精(jing)度(du)(du)控制在(zai)(zai)±15℃范圍內就可以(yi)了。但是(shi)(shi)，鎳基(ji)合(he)金(jin)特別是(shi)(shi)它在(zai)(zai)時效處理時的(de)(de)(de)(de)加熱(re)溫(wen)(wen)度(du)(du)精(jing)度(du)(du)，四川(chuan)筒類鍛件(jian)加工，則應達(da)到±5℃。對于高強度(du)(du)鋁合(he)金(jin)鍛件(jian)的(de)(de)(de)(de)熱(re)處理，也需要(yao)這樣高的(de)(de)(de)(de)溫(wen)(wen)度(du)(du)控制精(jing)度(du)(du)。為了保(bao)證達(da)到這樣高的(de)(de)(de)(de)精(jing)度(du)(du)，常采用所謂的(de)(de)(de)(de)“試(shi)(shi)塊熱(re)電偶”法。即用和(he)鍛件(jian)相同的(de)(de)(de)(de)材料作成試(shi)(shi)塊，試(shi)(shi)塊尺寸一般為 40*25*25(mm)，在(zai)(zai)其中插入(ru)熱(re)電偶，然后將(jiang)試(shi)(shi)塊置于鍛件(jian)中間(jian)以(yi)記錄爐子的(de)(de)(de)(de)溫(wen)(wen)度(du)(du)。

5.白點(dian)檢驗可(ke)(ke)在專(zhuan)門切下的試片上進行，也可(ke)(ke)在鍛件本體上用能保證檢驗可(ke)(ke)靠性的任一(yi)方法(fa)進行。
