1.不銹鋼封頭的鑄造

不銹鋼封頭在700℃以(yi)(yi)下(xia)(xia)鍛(duan)(duan)(duan)造，氧(yang)化皮(pi)形(xing)(xing)(xing)(xing)成(cheng)少(shao)，而且(qie)表(biao)(biao)面(mian)無脫(tuo)碳現象(xiang)。因此，只(zhi)要變形(xing)(xing)(xing)(xing)能在成(cheng)形(xing)(xing)(xing)(xing)能范圍(wei)內(nei)，冷鍛(duan)(duan)(duan)容易(yi)得(de)(de)(de)到(dao)(dao)很(hen)(hen)(hen)好的(de)(de)(de)尺寸(cun)精(jing)度(du)(du)(du)和表(biao)(biao)面(mian)光潔(jie)度(du)(du)(du)。只(zhi)要控(kong)制(zhi)好溫度(du)(du)(du)和潤滑冷卻，700℃以(yi)(yi)下(xia)(xia)的(de)(de)(de)溫螺紋(wen)管件，對(dui)焊(han)管件，不銹鋼管件鍛(duan)(duan)(duan)也可(ke)以(yi)(yi)獲(huo)(huo)得(de)(de)(de)很(hen)(hen)(hen)好的(de)(de)(de)精(jing)度(du)(du)(du)。熱(re)鍛(duan)(duan)(duan)時(shi)，由于變形(xing)(xing)(xing)(xing)能和變形(xing)(xing)(xing)(xing)阻(zu)(zu)力都很(hen)(hen)(hen)小，可(ke)以(yi)(yi)鍛(duan)(duan)(duan)造形(xing)(xing)(xing)(xing)狀復雜(za)的(de)(de)(de)大鍛(duan)(duan)(duan)件。要得(de)(de)(de)到(dao)(dao)高(gao)尺寸(cun)精(jing)度(du)(du)(du)的(de)(de)(de)鍛(duan)(duan)(duan)件，可(ke)在900-1000℃溫度(du)(du)(du)域內(nei)用熱(re)鍛(duan)(duan)(duan)加(jia)工(gong)。在700℃以(yi)(yi)下(xia)(xia)鍛(duan)(duan)(duan)造，氧(yang)化皮(pi)形(xing)(xing)(xing)(xing)成(cheng)少(shao)，而且(qie)表(biao)(biao)面(mian)無脫(tuo)碳現象(xiang)。因此，只(zhi)要變形(xing)(xing)(xing)(xing)能在成(cheng)形(xing)(xing)(xing)(xing)能范圍(wei)內(nei)，冷鍛(duan)(duan)(duan)容易(yi)得(de)(de)(de)到(dao)(dao)很(hen)(hen)(hen)好的(de)(de)(de)尺寸(cun)精(jing)度(du)(du)(du)和表(biao)(biao)面(mian)光潔(jie)度(du)(du)(du)。只(zhi)要控(kong)制(zhi)好溫度(du)(du)(du)和潤滑冷卻，700℃以(yi)(yi)下(xia)(xia)的(de)(de)(de)溫螺紋(wen)管件，對(dui)焊(han)管件，不銹鋼管件鍛(duan)(duan)(duan)也可(ke)以(yi)(yi)獲(huo)(huo)得(de)(de)(de)很(hen)(hen)(hen)好的(de)(de)(de)精(jing)度(du)(du)(du)。熱(re)鍛(duan)(duan)(duan)時(shi)，由于變形(xing)(xing)(xing)(xing)能和變形(xing)(xing)(xing)(xing)阻(zu)(zu)力都很(hen)(hen)(hen)小，可(ke)以(yi)(yi)鍛(duan)(duan)(duan)造形(xing)(xing)(xing)(xing)狀復雜(za)的(de)(de)(de)大鍛(duan)(duan)(duan)件。要得(de)(de)(de)到(dao)(dao)高(gao)尺寸(cun)精(jing)度(du)(du)(du)的(de)(de)(de)鍛(duan)(duan)(duan)件，可(ke)在900-1000℃溫度(du)(du)(du)域內(nei)用熱(re)鍛(duan)(duan)(duan)加(jia)工(gong)。

2.不銹鋼封頭的應用

不(bu)銹鋼封頭(tou)(tou)應用(yong)(yong)范圍：石油、電子、化工、輕紡、食(shi)品、機(ji)械、建筑、壓力(li)容器等行業。不(bu)銹鋼封頭(tou)(tou)是管(guan)道安(an)裝中常用(yong)(yong)的一種(zhong)連接用(yong)(yong)管(guan)件，連接兩根公稱通(tong)徑相同或者(zhe)不(bu)同的管(guan)子，使管(guan)路做角度(du)轉彎。
