以下內容由本公司為您提(ti)供(gong)，今天我們來分享(xiang)碳(tan)鋼鍛件的(de)內容，希望對大(da)家有所幫助：

鍛造鍛件(jian)時熱傳遞的基(ji)礎知識(shi)

熱傳(chuan)遞(di)是物體相互之間(jian)或同一(yi)物體內部(bu)(bu)熱能(neng)的(de)傳(chuan)遞(di)。溫度差(cha)(cha)是熱傳(chuan)遞(di)的(de)必(bi)要條(tiao)件。物體間(jian)或物體內部(bu)(bu)各部(bu)(bu)分之間(jian)只要存(cun)在著(zhu)溫度差(cha)(cha)，就(jiu)必(bi)然會產生熱試的(de)傳(chuan)遞(di)。

熱(re)(re)處(chu)理(li)操作中的加(jia)熱(re)(re)、保(bao)(bao)溫(wen)(wen)和冷(leng)卻的過(guo)程(cheng)(cheng)，都是熱(re)(re)量傳遞的過(guo)程(cheng)(cheng)。為了準(zhun)確(que)地控制加(jia)熱(re)(re)和冷(leng)卻的速度(du)，控制保(bao)(bao)溫(wen)(wen)時間及減少在此(ci)過(guo)程(cheng)(cheng)中的熱(re)(re)量損失，有必要學習(xi)傳熱(re)(re)學基礎(chu)知識。

熱(re)(re)傳(chuan)遞是一種復雜(za)的(de)物(wu)理(li)現象。熱(re)(re)傳(chuan)遞的(de)基本方式有三種：傳(chuan)導(dao)、對流(liu)和輻射(she)。

大家好(hao)本(ben)期小編給大家帶來新的內容(rong)，希望對(dui)大家有所(suo)幫助：碳鋼鍛件

大型鍛(duan)件的缺陷有(you)很多種(zhong)，但是常(chang)見的并對工件安全(quan)性造(zao)成(cheng)嚴重威脅的則主要有(you)以下幾(ji)種(zhong):裂紋、白點、縮孔、氣泡、夾(jia)雜(za)物等(deng)。

裂紋內含物多有空(kong)氣存在，空(kong)氣的(de)聲(sheng)阻數量(liang)級約(yue)為102，而(er)金(jin)屬(shu)材(cai)料的(de)聲(sheng)阻抗(kang)數量(liang)級約(yue)為106，可(ke)見空(kong)氣和金(jin)屬(shu)材(cai)料的(de)聲(sheng)學特性(xing)相差(cha)很(hen)大。由前述(shu)結論可(ke)知，裂紋與基體材(cai)料的(de)邊界是“軟(ruan)”邊界。

白點(dian)一般認(ren)為(wei)是由于工件熱處理過程中(zhong)氫逸散不充分(fen)，殘留在基(ji)體(ti)中(zhong)而(er)形(xing)成的(de)(de)。由于氫氣的(de)(de)聲學(xue)特(te)性(xing)阻(zu)(zu)抗(kang)約為(wei)1. 15 & 102，遠遠小(xiao)于金屬材料的(de)(de)聲學(xue)阻(zu)(zu)抗(kang)。因此，由前述結論可知(zhi)，白點(dian)缺陷與基(ji)體(ti)材料的(de)(de)邊界(jie)屬于“軟”邊界(jie)。

縮孔與氣(qi)泡這2種(zhong)缺陷的內含物(wu)均為氣(qi)體(ti)(ti)，氣(qi)體(ti)(ti)的聲特性(xing)阻(zu)抗數量級(ji)為102，遠小(xiao)于(yu)金(jin)屬(shu)材(cai)料的聲特性(xing)阻(zu)抗，所以這種(zhong)缺陷與基體(ti)(ti)材(cai)料邊界亦(yi)屬(shu)于(yu)“軟”邊界。

非金(jin)(jin)屬(shu)夾雜物(wu)(wu)主(zhu)(zhu)要(yao)是(shi)指鋼(gang)(gang)中(zhong)的(de)(de)(de)鐵及其他元素與(yu)氧、硫、氮等作用(yong)形成的(de)(de)(de)化合(he)物(wu)(wu)，陜西(xi)碳(tan)鋼(gang)(gang)鍛件，以及在(zai)煉鋼(gang)(gang)和澆(jiao)注過程中(zhong)混入鋼(gang)(gang)中(zhong)的(de)(de)(de)耐火材料(liao)碎(sui)片(pian)。由于這些碎(sui)片(pian)的(de)(de)(de)成分(fen)主(zhu)(zhu)要(yao)是(shi)S IA l Fe等的(de)(de)(de)氧化物(wu)(wu)，故(gu)可(ke)說鋼(gang)(gang)中(zhong)的(de)(de)(de)非金(jin)(jin)屬(shu)夾雜物(wu)(wu)是(shi)氣體(ti)在(zai)鋼(gang)(gang)中(zhong)存在(zai)的(de)(de)(de)一種形式。這類(lei)材料(liao)的(de)(de)(de)聲特性阻(zu)抗(kang)小(xiao)于金(jin)(jin)屬(shu)基體(ti)的(de)(de)(de)聲特性阻(zu)抗(kang)，所(suo)以這類(lei)缺陷與(yu)基體(ti)材料(liao)的(de)(de)(de)邊界可(ke)被認為(wei)是(shi)“軟”邊界。

大家(jia)(jia)好(hao)本期小編給大家(jia)(jia)帶來新的內容，希(xi)望對(dui)大家(jia)(jia)有所幫助：碳鋼鍛件

為了對鍛件熱處理(li)的(de)質(zhi)量進(jin)行(xing)控制，車間應(ying)采用(yong)一(yi)套配(pei)套的(de)措施，其中包(bao)括打(da)熱處理(li)爐批(pi)號(hao)、抽(chou)查硬(ying)度、定(ding)期(qi)檢查爐溫校(xiao)核儀表等等。作為參考，下面列舉了若干(gan)基本(ben)項目：

1)加熱爐的(de)結構要(yao)合理。爐膛尺寸、爐溫及(ji)爐膛內溫度的(de)均勻性能滿足(zu)熱處理的(de)需要(yao)；

2)淬火(huo)(huo)槽尺寸要足夠大。保證實現快速、均勻的冷卻。為了(le)控(kong)制(zhi)淬火(huo)(huo)液(ye)的溫度，還應配有熱(re)交(jiao)換(huan)器；

3)電(dian)位(wei)計(ji)要定期(qi)校核。加熱(re)爐應配備控制溫度和記錄溫度的電(dian)位(wei)計(ji)，由專人檢(jian)查記錄；

4)檢查(cha)和抽查(cha)硬(ying)度(du)。硬(ying)度(du)檢查(cha)是(shi)熱處(chu)理的(de)不可(ke)分割(ge)的(de)一(yi)(yi)部分，許多鋼號在(zai)回火(huo)過程(cheng)中，往往中途抽取一(yi)(yi)個鍛件進行硬(ying)度(du)檢查(cha)，以確定是(shi)否需要調整溫度(du)；

5)溫度(du)均勻性的檢查。爐溫均勻性的檢查應在正(zheng)常工作條件下進行，每半(ban)年一次；

6)根據(ju)化學(xue)成分調整熱處(chu)理制度。某些高溫合金或合金鋼(gang)，成分的微小變(bian)(bian)化都要求對(dui)時效或回火的佳溫度作相應(ying)改變(bian)(bian)；

7)作好記錄。必須使熱(re)處(chu)理爐的記錄與鍛(duan)件(jian)的熱(re)處(chu)理爐批(pi)號相對應(ying)。熱(re)處(chu)理爐批(pi)號好是打在鍛(duan)件(jian)上熔煉爐號的旁邊；
