鍛件的預成形坯：

在實際生(sheng)產中，預(yu)成形坯形狀選擇是(shi)極為(wei)重要的(de)，大體上分(fen)為(wei)兩類：

1）近似形狀，預成(cheng)形坯與(yu)終鍛件形狀相(xiang)近，類似熱(re)復壓的情況。

2）簡(jian)單形(xing)(xing)狀，預成形(xing)(xing)坯形(xing)(xing)狀較(jiao)簡(jian)單，與鍛(duan)件形(xing)(xing)狀差別較(jiao)大。一般是(shi)鍛(duan)件形(xing)(xing)狀的一種簡(jian)化(hua)。這種情況預成形(xing)(xing)坯鍛(duan)造(zao)時，不僅只是(shi)高向鐓粗變(bian)形(xing)(xing)或壓(ya)實，而(er)且(qie)通過較(jiao)大的塑性流動充滿模(mo)具(ju)型腔(qiang)。

對(dui)于(yu)形(xing)(xing)狀較復(fu)雜鍛件的預(yu)成形(xing)(xing)坯(pi)(pi)，可以對(dui)其不同部位及(ji)性(xing)能要求(qiu)，分別進行設計(ji)，以保證致密成形(xing)(xing)，不銹鋼(gang)筒類鍛件廠家，而不產(chan)生裂紋。如果采取近似形(xing)(xing)狀預(yu)成形(xing)(xing)坯(pi)(pi)，鍛造時只是簡單的軸(zhou)向(xiang)壓實(shi)，由于(yu)沒(mei)有水平方(fang)向(xiang)的塑性(xing)流動，不能滿足力學性(xing)能要求(qiu)。

為此必須重新考慮預成形坯的(de)(de)形狀(zhuang)。如(ru)果預成形坯內孔與芯(xin)軸之(zhi)間(jian)(jian)變(bian)形時過早的(de)(de)接觸，就會由于摩擦作用，產(chan)生(sheng)拉應變(bian)，導致法蘭頸(jing)的(de)(de)頂部(bu)產(chan)生(sheng)開(kai)裂(lie)。為此要求預成形坯內孔與芯(xin)軸之(zhi)間(jian)(jian)留(liu)有(you)一定間(jian)(jian)隙，以(yi)避(bi)免內表(biao)面過早接觸芯(xin)軸，需要選(xuan)擇合適的(de)(de)預成形坯內孔徑(jing)尺(chi)寸。

以下內容由(you)本公司(si)為您提供，今天我們來分享不(bu)銹鋼筒類鍛件(jian)的內容，希望對(dui)大家(jia)有所幫助(zhu)：

鍛圓的加工過程：

圓(yuan)鋼是(shi)指(zhi)截(jie)面為圓(yuan)形(xing)的(de)(de)實心長條鋼材。其規(gui)格以直徑的(de)(de)毫米(mi)數表示(shi)，如“ 50”即(ji)表示(shi)直徑為 50毫米(mi)的(de)(de)圓(yuan)鋼。

圓鋼與(yu)其(qi)它鋼筋(jin)的區別：

1 外型(xing)不一樣(yang)，圓鋼(gang)外型(xing)光園(yuan)，無(wu)紋無(wu)肋(lei)，其(qi)它鋼(gang)筋(jin)表面外型(xing)有刻紋或有肋(lei).這樣(yang)就造成圓鋼(gang)與(yu)混凝土的(de)粘結力小，而其(qi)它鋼(gang)筋(jin)與(yu)混凝土的(de)粘結力大.

2 成份不(bu)一樣，不(bu)銹鋼(gang)筒類鍛件價格(ge)，圓(yuan)鋼(gang)(一級(ji)鋼(gang))屬于普通低碳鋼(gang)，其它(ta)鋼(gang)筋多為合金(jin)鋼(gang).

3 強(qiang)度不一樣(yang).圓(yuan)鋼(gang)強(qiang)度低，其(qi)它(ta)鋼(gang)強(qiang)度高，即直徑大小相同(tong)的圓(yuan)鋼(gang)與其(qi)它(ta)鋼(gang)筋(jin)相比，圓(yuan)鋼(gang)所(suo)能承受的拉(la)力要比其(qi)它(ta)鋼(gang)筋(jin)小。

以下內容由本公(gong)司為您提(ti)供，今天我們來分(fen)享不銹鋼筒類(lei)鍛件的內容，希望對大家有所(suo)幫助：

鍛件的下(xia)料(liao)：直徑(jing)>40mm的棒(bang)料(liao)多(duo)用圓盤鋸切割(ge)，小直徑(jing)棒(bang)材可用砂輪切割(ge)。當要求較高時可用車床(chuang)下(xia)料(liao)。馬氏體原材料(liao)表面若有劃痕(hen)等缺陷(xian)，需用車床(chuang)剝皮或用無心磨磨去(qu)。

鍛件的加熱：鍛前加熱可(ke)以(yi)用電(dian)爐，也可(ke)以(yi)用火焰爐。生產(chan)中(zhong)多用火焰爐。對于奧氏(shi)體(ti)不(bu)銹(xiu)鋼，爐氣(qi)(qi)應保持中(zhong)性或微(wei)氧(yang)化性，以(yi)免(mian)產(chan)生滲碳造(zao)成晶(jing)間腐蝕；對于馬氏(shi)體(ti)不(bu)銹(xiu)鋼，不(bu)可(ke)以(yi)采(cai)用過分氧(yang)化氣(qi)(qi)氛，以(yi)免(mian)引起嚴重脫碳。

在700~800℃以下(xia)(xia)，不(bu)銹鋼(gang)的熱(re)(re)導(dao)率比較(jiao)小，因此(ci)不(bu)銹鋼(gang)鍛(duan)件鍛(duan)造(zao)需要(yao)的加(jia)熱(re)(re)時間(jian)較(jiao)長。鐵素體(ti)不(bu)銹鋼(gang)加(jia)熱(re)(re)到高溫時晶粒(li)長大傾向嚴(yan)重(zhong)，造(zao)成(cheng)較(jiao)大脆性，馬氏體(ti)不(bu)銹鋼(gang)在高溫下(xia)(xia)氧化(hua)、脫碳特別嚴(yan)重(zhong)，它們都(dou)要(yao)求(qiu)盡(jin)量縮短在高溫下(xia)(xia)的加(jia)熱(re)(re)時間(jian)。所以這(zhe)兩(liang)類鋼(gang)，以及直徑或厚(hou)度超(chao)過100mm的奧氏體(ti)不(bu)銹鋼(gang)，一般采用兩(liang)階段加(jia)熱(re)(re)：先(xian)緩慢加(jia)熱(re)(re)到850℃，然后快(kuai)速(su)加(jia)熱(re)(re)到始鍛(duan)溫度。

對于(yu)直(zhi)接投入(ru)高(gao)溫(wen)爐(lu)中加(jia)熱(re)(re)的毛(mao)坯，從入(ru)爐(lu)算(suan)起，加(jia)熱(re)(re)時間按2mm/min計算(suan)；對于(yu)分成兩段加(jia)熱(re)(re)的毛(mao)坯，預熱(re)(re)階(jie)段時間按2mm/min計算(suan)，后一階(jie)段加(jia)熱(re)(re)時間按3mm/min計算(suan)。

對于精(jing)密鍛件或小余量的(de)(de)重要(yao)鍛件，加(jia)熱前應在(zai)毛坯表面涂一層玻璃潤滑(hua)劑，然后再加(jia)熱。玻璃潤滑(hua)劑的(de)(de)配置一般按57%的(de)(de)玻璃、3%的(de)(de)黏土和40%的(de)(de)水。含(han)鎳(nie)量較高(gao)的(de)(de)不(bu)銹鋼必須采用不(bu)含(han)硫的(de)(de)燃料(liao)加(jia)熱，因(yin)硫滲入鋼中與鎳(nie)形成低熔點硫化物及共晶(jing)體分布在(zai)晶(jing)界上(shang)，高(gao)溫鍛造時會產生晶(jing)間(jian)裂紋。
