環形(xing)鍛(duan)(duan)(duan)件(jian)是鍛(duan)(duan)(duan)造(zao)(zao)(zao)(zao)行業(ye)中的(de)(de)(de)(de)產(chan)物(wu)，鍛(duan)(duan)(duan)件(jian)的(de)(de)(de)(de)一(yi)種(zhong)類(lei)型(xing)。是金屬坯料(不含(han)板(ban)材)施加外(wai)力(li)，通(tong)過塑(su)(su)性(xing)變形(xing)塑(su)(su)造(zao)(zao)(zao)(zao)的(de)(de)(de)(de)要(yao)求變成合適的(de)(de)(de)(de)壓(ya)縮(suo)力(li)的(de)(de)(de)(de)環形(xing)物(wu)件(jian)。這種(zhong)力(li)量典型(xing)的(de)(de)(de)(de)通(tong)過使用鐵錘或壓(ya)力(li)來實現。鍛(duan)(duan)(duan)件(jian)過程(cheng)建造(zao)(zao)(zao)(zao)了精致的(de)(de)(de)(de)顆粒結構(gou)，并改進了金屬的(de)(de)(de)(de)物(wu)理屬性(xing)。環形(xing)鍛(duan)(duan)(duan)件(jian)在日常生(sheng)活中隨處(chu)可見，是一(yi)種(zhong)工(gong)(gong)業(ye)制品(pin)。環形(xing)鍛(duan)(duan)(duan)件(jian)在我國已有(you)數(shu)千年的(de)(de)(de)(de)歷史。機器鍛(duan)(duan)(duan)造(zao)(zao)(zao)(zao)是在各(ge)種(zhong)鍛(duan)(duan)(duan)造(zao)(zao)(zao)(zao)設備(bei)上采用鍛(duan)(duan)(duan)造(zao)(zao)(zao)(zao)工(gong)(gong)具進行的(de)(de)(de)(de)。機器鍛(duan)(duan)(duan)造(zao)(zao)(zao)(zao)按(an)所用設備(bei)和工(gong)(gong)具的(de)(de)(de)(de)不同，可分(fen)為自(zi)由(you)鍛(duan)(duan)(duan)造(zao)(zao)(zao)(zao)、模(mo)(mo)型(xing)鍛(duan)(duan)(duan)造(zao)(zao)(zao)(zao)、胎模(mo)(mo)鍛(duan)(duan)(duan)造(zao)(zao)(zao)(zao)和特種(zhong)鍛(duan)(duan)(duan)造(zao)(zao)(zao)(zao)四類(lei)。

根(gen)據(ju)擴(kuo)(kuo)孔(kong)機上型槽形式不(bu)同，輾擴(kuo)(kuo)工藝可分為(wei)開式輾擴(kuo)(kuo)和閉式輾擴(kuo)(kuo)兩種。

(1)開式輾擴(kuo)。開式輾擴(kuo)采用(yong)平輥，主要用(yong)于(yu)大(da)型矩形(xing)斷面的環形(xing)件(jian)擴(kuo)孔(kong)。其優點是用(yong)同一對軋輥可輾擴(kuo)不同尺(chi)寸的圓環。為了避免由不均(jun)勻變形(xing)引起(qi)的增寬，可在擴(kuo)孔(kong)機上增加兩對自由轉動的錐形(xing)鍛，使坯料在高(gao)度上獲得(de)的尺(chi)寸，此種情況也可稱為半開式輾擴(kuo)。

(2)閉式(shi)輾擴。閉式(shi)輾擴軋輥(gun)型槽按工件(jian)斷面形(xing)(xing)狀要求設計，可用于各種(zhong)斷面的環形(xing)(xing)件(jian)擴孔成形(xing)(xing)。

鍛造工藝不當會使鍛件產生(sheng)缺陷嗎？

鍛(duan)件的缺陷(xian)(xian)包(bao)括表面(mian)缺陷(xian)(xian)和內(nei)部缺陷(xian)(xian)。有的鍛(duan)件缺陷(xian)(xian)會(hui)影(ying)響后(hou)續工(gong)序的加工(gong)質(zhi)量，有的則(ze)嚴重影(ying)響鍛(duan)件的性(xing)能，降低所制成品件的使(shi)用壽(shou)命，甚(shen)至危及安全。因此，為提高鍛(duan)件質(zhi)量，避免鍛(duan)件缺陷(xian)(xian)的產生(sheng)，應(ying)(ying)采取相(xiang)應(ying)(ying)的工(gong)藝對策(ce)，同時還應(ying)(ying)加強生(sheng)產全過(guo)程的質(zhi)量控制。

鍛造(zao)工(gong)藝(yi)過(guo)(guo)(guo)程對鍛件質量的(de)(de)影響鍛造(zao)工(gong)藝(yi)過(guo)(guo)(guo)程一般由以(yi)下工(gong)序(xu)組成，即下料(liao)、加(jia)熱(re)、成形、鍛后(hou)冷(leng)卻、酸洗及鍛后(hou)熱(re)處理。鍛造(zao)過(guo)(guo)(guo)程中(zhong)如果(guo)工(gong)藝(yi)不當(dang)將可能產生(sheng)(sheng)一系列(lie)的(de)(de)鍛件缺(que)陷(xian)。加(jia)熱(re)工(gong)藝(yi)包括裝(zhuang)爐(lu)溫(wen)(wen)度、加(jia)熱(re)溫(wen)(wen)度、加(jia)熱(re)速度、保(bao)(bao)溫(wen)(wen)時間、爐(lu)氣成分(fen)等。如果(guo)加(jia)熱(re)不當(dang)，忻州鍛件加(jia)工(gong)，例如加(jia)熱(re)溫(wen)(wen)度過(guo)(guo)(guo)高(gao)和(he)加(jia)熱(re)時間過(guo)(guo)(guo)長(chang)，將會(hui)引(yin)起脫碳、過(guo)(guo)(guo)熱(re)、過(guo)(guo)(guo)燒等缺(que)陷(xian)。對于斷面(mian)尺寸(cun)大及導熱(re)性差、塑性低的(de)(de)坯(pi)料(liao)，若加(jia)熱(re)速度太(tai)快，保(bao)(bao)溫(wen)(wen)時間太(tai)短，往往使(shi)溫(wen)(wen)度分(fen)布不均勻，引(yin)起熱(re)應(ying)力，并(bing)使(shi)坯(pi)料(liao)發生(sheng)(sheng)開裂。

山西鍛件廠的余熱利用有什么意義？

機(ji)械零件大(da)量采用(yong)碳素結構(gou)鋼和低合金結構(gou)鋼，其鍛(duan)件被常用(yong)的(de)熱(re)處理工藝(yi)為(wei)正火、等溫(wen)正火、退火和調質。

調質能耗：采(cai)用連續(xu)(xu)式電阻(zu)爐，淬火溫(wen)度840℃~860℃，每(mei)kg鍛件實(shi)際(ji)耗電約(yue)為(wei)0.6kWh.采(cai)用連續(xu)(xu)式電阻(zu)同火爐，回火溫(wen)度550℃~650℃，每(mei)kg鍛件實(shi)際(ji)耗電約(yue)0.4kWh。

正火能耗(hao)：采用連續式電阻(zu)爐，S30408鍛件加工，正火溫(wen)度930℃~960℃，每kg鍛件實際耗(hao)電為0.5kWh。

等溫(wen)正(zheng)火(huo)能耗(hao)：采用連(lian)續式電阻等溫(wen)正(zheng)火(huo)爐，軸承鍛件機加(jia)工(gong)廠家，加(jia)熱溫(wen)度(du)(du)為(wei)920℃~940℃，快速冷卻，等溫(wen)溫(wen)度(du)(du)600℃~650℃，每kg鍛件實際能耗(hao)約為(wei)0.8kWh。 

以上數據是(shi)統計(ji)連(lian)續式電阻(zu)爐(lu)全(quan)年的實(shi)際(ji)(ji)(ji)平均值，例如實(shi)際(ji)(ji)(ji)測(ce)量連(lian)續式鑄鏈(lian)電阻(zu)淬火爐(lu)24h生(sheng)產(chan)的單位電耗約0.5kWh/kg，但是(shi)，由于在全(quan)年生(sheng)產(chan)過程(cheng)中，故(gu)障停爐(lu)等各種(zhong)原因反(fan)復升溫，其(qi)每千克(ke)鍛件實(shi)際(ji)(ji)(ji)耗電為0.6kWh。

以(yi)上數(shu)據僅(jin)供參(can)考，因為鍛件熱處理能耗(hao)(hao)大(da)小由(you)爐(lu)型、裝(zhuang)載方(fang)(fang)式(shi)(shi)、鋼種和(he)生產方(fang)(fang)式(shi)(shi)決定，其中周(zhou)期加熱爐(lu)比連(lian)續加熱爐(lu)能耗(hao)(hao)大(da)，例(li)如(ru)連(lian)續式(shi)(shi)網(wang)帶(dai)電(dian)阻(zu)(zu)(zu)爐(lu)或連(lian)續式(shi)(shi)鑄鏈電(dian)阻(zu)(zu)(zu)爐(lu)能耗(hao)(hao)損失較小，而臺車式(shi)(shi)電(dian)阻(zu)(zu)(zu)爐(lu)能耗(hao)(hao)損失就較大(da)。

由以上(shang)分(fen)析(xi)可知，鍛件(jian)在(zai)熱(re)處理過程(cheng)中要消耗很多能源(yuan)，因此國外工(gong)(gong)業發達國家均高度(du)重視鍛件(jian)的余熱(re)利用，大量采用鍛件(jian)余熱(re)熱(re)處理工(gong)(gong)藝，國內使用也(ye)較多，但尚不普及。
