試著(zhu)解釋如(ru)下：1、滲氮(dan)爐(lu)的(de)基本爐(lu)氣(qi)(qi)(qi)(qi)(qi)(qi)為氨氣(qi)(qi)(qi)(qi)(qi)(qi)＋氮(dan)氣(qi)(qi)(qi)(qi)(qi)(qi)＋氫(qing)氣(qi)(qi)(qi)(qi)(qi)(qi),其中(zhong)(zhong)(zhong)(zhong)(zhong)氫(qing)氣(qi)(qi)(qi)(qi)(qi)(qi)和氨氣(qi)(qi)(qi)(qi)(qi)(qi)都是可燃氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti),與空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)混合至一定(ding)比例范圍時(shi),遇(yu)明(ming)火（含火星(xing)）或者達到(dao)著(zhu)火溫度(du)（510℃以上(shang)）即可燃燒,在(zai)密(mi)封(feng)容(rong)器中(zhong)(zhong)(zhong)(zhong)(zhong)表現(xian)(xian)(xian)為爆炸,敞(chang)口(kou)容(rong)器中(zhong)(zhong)(zhong)(zhong)(zhong)表現(xian)(xian)(xian)為爆燃。2、此時(shi)爐(lu)溫已在(zai)200℃以下,打開爐(lu)蓋(gai),盡管有(you)空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)進入,在(zai)沒有(you)明(ming)火點(dian)燃的(de)情況下,本應該不會發生氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)燃燒（爆燃）現(xian)(xian)(xian)象(xiang)。3、當然,這(zhe)其中(zhong)(zhong)(zhong)(zhong)(zhong)有(you)一個問題(ti),即氫(qing)氣(qi)(qi)(qi)(qi)(qi)(qi)是強還(huan)(huan)原(yuan)性氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti),隨爐(lu)冷卻過程中(zhong)(zhong)(zhong)(zhong)(zhong)它會將散(san)落在(zai)爐(lu)罐(guan)內的(de)呈微(wei)粒（灰塵）狀態的(de)鐵氮(dan)化物還(huan)(huan)原(yuan)成(cheng)鐵粉(fen)(fen).我們知道微(wei)小的(de)還(huan)(huan)原(yuan)鐵粉(fen)(fen)遇(yu)空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)會強烈(lie)氧(yang)化而發熱,溫度(du)急劇升高而成(cheng)為火星(xing),另(ling)外氮(dan)碳(tan)共(gong)滲過程中(zhong)(zhong)(zhong)(zhong)(zhong)可能(neng)沉積的(de)活性炭粉(fen)(fen)遇(yu)空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)也會氧(yang)化成(cheng)為火星(xing).火星(xing)點(dian)燃“氫(qing)氣(qi)(qi)(qi)(qi)(qi)(qi)（氨氣(qi)(qi)(qi)(qi)(qi)(qi)）－空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)”混合氣(qi)(qi)(qi)(qi)(qi)(qi),于(yu)是出現(xian)(xian)(xian)爆燃現(xian)(xian)(xian)。

箱式氣體滲(shen)(shen)碳(tan)氮化熱(re)(re)處(chu)理自動(dong)(dong)生產(chan)(chan)線是(shi)(shi)(shi)成套機組(zu)。該生產(chan)(chan)線由(you)加熱(re)(re)爐(lu)(lu)、清(qing)洗(xi)機、回火(huo)爐(lu)(lu)、推(tui)拉車(che)、備料臺(tai)等(deng)組(zu)成，控制系統及主(zhu)要執行元(yuan)件(jian)采用(yong)(yong)國外先進國家(jia)進口(kou)原件(jian)，可實(shi)現(xian)全自動(dong)(dong)或手動(dong)(dong)操(cao)作，既適用(yong)(yong)于單品種(zhong)大批量生產(chan)(chan)，也(ye)適用(yong)(yong)于多品種(zhong)小批量生產(chan)(chan)，操(cao)作簡便，運轉成本低，可實(shi)現(xian)產(chan)(chan)品的(de)滲(shen)(shen)碳(tan)、碳(tan)氮共滲(shen)(shen)、光亮淬火(huo)、退(tui)火(huo)、正(zheng)火(huo)等(deng)熱(re)(re)處(chu)理工藝。的(de)布置是(shi)(shi)(shi)指爐(lu)(lu)底(di)和爐(lu)(lu)壁的(de)布線情(qing)況，2-1-1是(shi)(shi)(shi)指爐(lu)(lu)底(di)兩(liang)(liang)組(zu)，兩(liang)(liang)邊各一(yi)組(zu)，去了這(zhe)些可以根(gen)據爐(lu)(lu)子(zi)的(de)情(qing)況及需要溫(wen)(wen)度做出調整不是(shi)(shi)(shi)硬性規定(ding)，多一(yi)組(zu)兩(liang)(liang)組(zu)也(ye)行，只要溫(wen)(wen)控得當就行。那數字是(shi)(shi)(shi)指的(de)生產(chan)(chan)線中滲(shen)(shen)碳(tan)爐(lu)(lu)與其它配套設備比例的(de)問題，2-1-1是(shi)(shi)(shi)指兩(liang)(liang)臺(tai)滲(shen)(shen)碳(tan)爐(lu)(lu)共用(yong)(yong)一(yi)臺(tai)回火(huo)爐(lu)(lu)和一(yi)個清(qing)洗(xi)機。因(yin)為滲(shen)(shen)碳(tan)的(de)實(shi)際較長(chang)回火(huo)和清(qing)洗(xi)的(de)時(shi)間較短，如果滲(shen)(shen)碳(tan)爐(lu)(lu)錯開時(shi)間裝(zhuang)料那么清(qing)洗(xi)和回火(huo)就會分時(shi)進行。如何配置主(zhu)要看實(shi)際的(de)生產(chan)(chan)情(qing)況。

其設備的(de)(de)特(te)點：(1)、氣(qi)(qi)(qi)(qi)體(ti)(ti)氮(dan)(dan)化(hua)爐(lu)(lu)處理溫(wen)度低(di)，時間短，工件(jian)(jian)變(bian)形小。(2)、氣(qi)(qi)(qi)(qi)體(ti)(ti)氮(dan)(dan)化(hua)爐(lu)(lu)不(bu)受(shou)鋼種限(xian)制，碳鋼、低(di)合金鋼、工模具(ju)(ju)鋼、不(bu)銹鋼、鑄鐵及鐵基(ji)粉未冶(ye)金材料(liao)均可(ke)進行(xing)軟(ruan)氮(dan)(dan)化(hua)處理。氣(qi)(qi)(qi)(qi)體(ti)(ti)氮(dan)(dan)化(hua)爐(lu)(lu)工件(jian)(jian)經軟(ruan)氮(dan)(dan)化(hua)后的(de)(de)表面硬度與(yu)氮(dan)(dan)化(hua)工藝及材料(liao)有(you)關。(3)、能顯著地(di)提(ti)高(gao)工件(jian)(jian)的(de)(de)疲勞(lao)強(qiang)度、耐(nai)磨性(xing)(xing)和(he)耐(nai)腐蝕(shi)性(xing)(xing)。氣(qi)(qi)(qi)(qi)體(ti)(ti)氮(dan)(dan)化(hua)爐(lu)(lu)在干摩擦條件(jian)(jian)下還具(ju)(ju)有(you)抗(kang)(kang)擦傷和(he)抗(kang)(kang)咬合等性(xing)(xing)能。(4)、氣(qi)(qi)(qi)(qi)體(ti)(ti)氮(dan)(dan)化(hua)爐(lu)(lu)由于軟(ruan)氮(dan)(dan)化(hua)層不(bu)存在脆(cui)性(xing)(xing)相，故氮(dan)(dan)化(hua)層因而(er)具(ju)(ju)有(you)一定的(de)(de)韌性(xing)(xing)，不(bu)容(rong)易剝落。因此，目(mu)前氣(qi)(qi)(qi)(qi)體(ti)(ti)氮(dan)(dan)化(hua)爐(lu)(lu)生產(chan)中軟(ruan)氮(dan)(dan)化(hua)已廣泛(fan)應用于模具(ju)(ju)、量(liang)具(ju)(ju)、刀具(ju)(ju)(如(ru)：高(gao)速(su)鋼刀具(ju)(ju))等、曲軸、齒輪、氣(qi)(qi)(qi)(qi)缸套、機械(xie)結構件(jian)(jian)等耐(nai)磨工件(jian)(jian)的(de)(de)處理。
