以下(xia)內容(rong)由(you)本公司(si)為您提(ti)供，今天(tian)我們來(lai)分享筒類鍛件定制的內容(rong)，希望對(dui)大(da)家(jia)有所幫助：

不銹鋼鍛(duan)件出現裂紋缺陷的原因？

表面裂(lie)紋是因鍛(duan)(duan)造溫度(du)過(guo)(guo)(guo)高或錘擊速度(du)過(guo)(guo)(guo)快，使坯(pi)料(liao)發生(sheng)過(guo)(guo)(guo)燒(shao)或過(guo)(guo)(guo)熱而引起的，裂(lie)口較寬，斷口凹凸不平，組織粗大(da)呈(cheng)暗灰色。低倍組織中裂(lie)紋端為鋸(ju)齒形，與流線無(wu)關。高倍觀察裂(lie)紋沿晶界伸展，再結(jie)晶完全，無(wu)夾雜及(ji)其他冶金缺陷(xian)。鍛(duan)(duan)造溫度(du)過(guo)(guo)(guo)低，錘擊過(guo)(guo)(guo)重(zhong)時(shi)，在坯(pi)料(liao)側(ce)表面與錘擊方向呈(cheng)三角形裂(lie)紋，斷口平齊有(you)金屬光澤。高倍觀察，裂(lie)紋穿(chuan)晶并有(you)加(jia)工硬(ying)化現象(xiang)。

內部(bu)(bu)裂(lie)紋一(yi)(yi)種(zhong)是(shi)在(zai)自由(you)(you)鍛(duan)時(shi)發生(sheng)(sheng)的。在(zai)圓截面坯料拔(ba)長、滾圓時(shi)，由(you)(you)于(yu)(yu)送進量太(tai)大(da)，壓下量太(tai)小，寧(ning)夏筒類鍛(duan)件定制(zhi)，金(jin)屬(shu)橫(heng)向流動激烈而產生(sheng)(sheng)橫(heng)向拉應(ying)力，愈接近心部(bu)(bu)拉應(ying)力愈大(da)，引起內部(bu)(bu)縱向裂(lie)紋。另一(yi)(yi)種(zhong)內部(bu)(bu)裂(lie)紋則是(shi)由(you)(you)合金(jin)內部(bu)(bu)過(guo)分粗大(da)的金(jin)屬(shu)間化合物或夾雜物在(zai)鍛(duan)造時(shi)阻(zu)礙著金(jin)屬(shu)的規則流動，在(zai)其(qi)周圍引起的微裂(lie)紋。通常此種(zhong)裂(lie)紋都要(yao)在(zai)不(bu)銹鋼(gang)鍛(duan)件加工后才能表露出(chu)來。前一(yi)(yi)種(zhong)縱向裂(lie)紋的防(fang)止方(fang)法是(shi)在(zai)圓坯料拔(ba)長時(shi)，先打四方(fang)后打八方(fang)后滾圓，每次(ci)壓下量要(yao)大(da)于(yu)(yu)20%。后一(yi)(yi)種(zhong)裂(lie)紋的防(fang)止方(fang)法是(shi)要(yao)對鍛(duan)造毛坯嚴格檢查，控制(zhi)組織不(bu)合格的坯料進入車問。

以下內容由本公司為您(nin)提供，今(jin)天(tian)我們來分享筒類鍛件(jian)定制的內容，希望對大家有所(suo)幫(bang)助：

金屬鍛(duan)造溫度范圍怎(zen)么確(que)定？

金(jin)屬的鍛(duan)造溫度(du)范圍是指開始(shi)鍛(duan)造溫度(du)（始(shi)鍛(duan)溫度(du)）與結束鍛(duan)造溫度(du)（終鍛(duan)溫度(du)）之(zhi)間的一段溫度(du)區間。

確定鍛(duan)造溫度(du)范圍(wei)的原則：要求在鍛(duan)造溫度(du)范圍(wei)內(nei)金(jin)屬具有良好的塑性和較低(di)的變形抗力；能(neng)夠獲得鍛(duan)件(jian)；溫度(du)范圍(wei)盡可能(neng)寬(kuan)，以便(bian)減少加熱次(ci)數(shu)，提(ti)高生產率。

金屬鍛造溫度根據下列因素(su)確定。

合金(jin)的相(xiang)(xiang)圖  相(xiang)(xiang)圖是表示合金(jin)的成(cheng)分在不同(tong)溫(wen)度范圍(wei)區間所具有的組(zu)織(zhi)狀態(tai)(tai)。因(yin)此可根(gen)據金(jin)屬的組(zu)織(zhi)形(xing)(xing)態(tai)(tai)來確定其鍛造溫(wen)度范圍(wei)。一般(ban)單(dan)相(xiang)(xiang)組(zu)織(zhi)比多(duo)相(xiang)(xiang)組(zu)織(zhi)塑(su)性好，變形(xing)(xing)抗(kang)力低。多(duo)相(xiang)(xiang)組(zu)織(zhi)變形(xing)(xing)不均勻，塑(su)性低.變形(xing)(xing)抗(kang)力高。鍛造時盡可能使合金(jin)處于單(dan)相(xiang)(xiang)組(zu)織(zhi)狀態(tai)(tai)，筒類鍛件定制加工，以提高塑(su)性和有利(li)于成(cheng)形(xing)(xing)。

III級鍛件(jian)(jian)要同冶(ye)煉號、同爐熱處理的鍛件(jian)(jian)組成一(yi)批、每批抽檢一(yi)件(jian)(jian)做(zuo)拉伸和沖擊，并且逐件(jian)(jian)做(zuo)超(chao)聲檢驗；

IV級(ji)鍛件(jian)要逐(zhu)件(jian)檢驗(yan)拉(la)伸和(he)沖(chong)擊(ji)，并且逐(zhu)件(jian)做超聲檢驗(yan)。
