自由(you)鍛件鐓粗工序作用(yong)是什么？

鍛(duan)件鐓粗處理是自由鍛(duan)造常用(yong)的生(sheng)(sheng)產(chan)工(gong)(gong)藝之(zhi)一，主(zhu)要是在(zai)外(wai)力作(zuo)用(yong)下，減少鍛(duan)件皮料(liao)高度，增(zeng)大(da)橫截面(mian)積(ji)的鍛(duan)造工(gong)(gong)序(xu)，鍛(duan)件鐓粗處理可(ke)獲(huo)得橫截面(mian)積(ji)較(jiao)大(da)且高度較(jiao)小的鍛(duan)件，可(ke)用(yong)于沖(chong)孔前準(zhun)備(bei)工(gong)(gong)序(xu)，增(zeng)大(da)鍛(duan)件坯料(liao)橫截面(mian)積(ji)以便于沖(chong)孔等操作(zuo)。鍛(duan)件廠鐓粗工(gong)(gong)序(xu)是鍛(duan)造生(sheng)(sheng)產(chan)工(gong)(gong)藝的一種，是在(zai)外(wai)力作(zuo)用(yong)下，使鍛(duan)件的坯料(liao)高度減小，橫截面(mian)增(zeng)大(da)的鍛(duan)造工(gong)(gong)序(xu)。

鐓粗的作用：

1、獲(huo)得橫截面較(jiao)大(da)而(er)且(qie)高度較(jiao)小(xiao)的鍛件；

2、用(yong)作沖(chong)孔(kong)前的準備工序，增大(da)鍛件的坯(pi)料橫截面積以(yi)便(bian)于沖(chong)孔(kong)；

3、反復鐓(dui)拔法，鐓(dui)粗與拔長相(xiang)結(jie)合，可提高(gao)鍛造比(bi)，同時擊(ji)碎合金(jin)工(gong)具鋼中的塊狀碳化物(wu)，并使其分布均勻以提高(gao)鍛件的使用性能；

4、提(ti)高鍛件的橫向力學性能(neng)以減小力學性能(neng)的異(yi)向性。

以下內容(rong)由本公(gong)司(si)為您(nin)提(ti)供，今天(tian)我們來(lai)分享(xiang)鍛件定(ding)制(zhi)加工的內容(rong)，希望對(dui)大家有(you)所幫(bang)助：

不銹鋼(gang)鍛件(jian)在鍛造加(jia)熱(re)(re)過程減少(shao)氧化的(de)措施有：在保證鍛件(jian)質量的(de)前提(ti)下(xia)，盡量采(cai)用快(kuai)速(su)加(jia)熱(re)(re)，縮短(duan)(duan)加(jia)熱(re)(re)時間，尤(you)其是縮短(duan)(duan)高溫下(xia)停留的(de)時間；在燃料完全燃燒的(de)條件(jian)下(xia)，盡可能減少(shao)空氣過剩(sheng)量，以(yi)免爐(lu)內剩(sheng)余氧氣過多，注意(yi)減少(shao)燃料中(zhong)的(de)水分；爐(lu)內應(ying)保持(chi)不大的(de)正壓力，防(fang)止冷(leng)空氣的(de)吸入(ru)；采(cai)用少(shao)無氧化加(jia)熱(re)(re)方法。

燃(ran)料(liao)爐(lu)(lu)的(de)爐(lu)(lu)氣(qi)(qi)(qi)性質可(ke)(ke)(ke)分為氧(yang)化(hua)性爐(lu)(lu)氣(qi)(qi)(qi)、還原性爐(lu)(lu)氣(qi)(qi)(qi)和中(zhong)(zhong)性爐(lu)(lu)氣(qi)(qi)(qi)。爐(lu)(lu)氣(qi)(qi)(qi)性質決定于燃(ran)料(liao)燃(ran)燒時的(de)空氣(qi)(qi)(qi)供給在強氧(yang)化(hua)性爐(lu)(lu)氣(qi)(qi)(qi)中(zhong)(zhong)，爐(lu)(lu)氣(qi)(qi)(qi)可(ke)(ke)(ke)能完全由氧(yang)化(hua)性氣(qi)(qi)(qi)體，這(zhe)將(jiang)使(shi)金屬(shu)產生較厚的(de)氧(yang)化(hua)皮。在還原性爐(lu)(lu)氣(qi)(qi)(qi)中(zhong)(zhong)，含(han)有足夠量的(de)還原性氣(qi)(qi)(qi)體，如CO、H2等，它可(ke)(ke)(ke)以使(shi)金屬(shu)不氧(yang)化(hua)或很少氧(yang)化(hua)。普通電阻爐(lu)(lu)在空氣(qi)(qi)(qi)介質中(zhong)(zhong)加(jia)熱，屬(shu)于氧(yang)化(hua)性爐(lu)(lu)氣(qi)(qi)(qi)。

加熱(re)溫(wen)度是影響金屬氧(yang)(yang)化速度主要(yao)的因素。溫(wen)度越(yue)高，金屬和氣體原(yuan)子擴散速度越(yue)大(da)，則氧(yang)(yang)化越(yue)劇烈(lie)，生(sheng)成(cheng)的氧(yang)(yang)化皮越(yue)厚。實際(ji)觀(guan)察表明(ming)，在200-500℃時(shi)，鋼(gang)料表面(mian)僅能生(sheng)成(cheng)很薄的一層氧(yang)(yang)化膜，當溫(wen)度升至600-700℃時(shi)，便開始有顯著氧(yang)(yang)化，并生(sheng)成(cheng)氧(yang)(yang)化皮，超(chao)過(guo)850-900℃，鋼(gang)的氧(yang)(yang)化速度急劇升高，氧(yang)(yang)化會(hui)急劇增(zeng)加，坯料的氧(yang)(yang)化層較厚。

坯(pi)料在氧化(hua)性氣(qi)氛中的(de)加熱時間越長，氧的(de)擴散坩越大，形成的(de)氧化(hua)皮(pi)越厚。特(te)別是(shi)加熱到高溫階段(duan)，加熱時間的(de)影響更加顯著。
