35號無縫管的生產過程
軋制無縫(feng)管(guan)(guan)(guan)的(de)原料(liao)(liao)是(shi)圓(yuan)(yuan)管(guan)(guan)(guan)坯(pi)(pi)，圓(yuan)(yuan)管(guan)(guan)(guan)胚要經(jing)過切割(ge)機(ji)的(de)切割(ge)加工成(cheng)長度(du)(du)(du)約(yue)為(wei)1米的(de)坯(pi)(pi)料(liao)(liao)，并經(jing)傳送(song)(song)帶送(song)(song)到熔(rong)爐(lu)內加熱(re)。鋼(gang)(gang)坯(pi)(pi)被送(song)(song)入熔(rong)爐(lu)內加熱(re)，溫度(du)(du)(du)大約(yue)為(wei)1200℃。燃料(liao)(liao)為(wei)氫氣(qi)或乙(yi)炔。爐(lu)內溫度(du)(du)(du)控制是(shi)關鍵性的(de)問題(ti).圓(yuan)(yuan)管(guan)(guan)(guan)坯(pi)(pi)出爐(lu)后(hou)(hou)要經(jing)過壓(ya)力穿(chuan)(chuan)(chuan)孔機(ji)進(jin)行穿(chuan)(chuan)(chuan)空(kong)。一般(ban)較(jiao)常見(jian)的(de)穿(chuan)(chuan)(chuan)孔機(ji)是(shi)錐形輥(gun)穿(chuan)(chuan)(chuan)孔機(ji)，這種穿(chuan)(chuan)(chuan)孔機(ji)生產(chan)效(xiao)率高(gao)，產(chan)品質量好，穿(chuan)(chuan)(chuan)孔擴徑(jing)(jing)(jing)量大，可穿(chuan)(chuan)(chuan)多種鋼(gang)(gang)種。穿(chuan)(chuan)(chuan)孔后(hou)(hou)，圓(yuan)(yuan)管(guan)(guan)(guan)坯(pi)(pi)就先后(hou)(hou)被三輥(gun)斜軋、連軋或擠(ji)壓(ya)。擠(ji)壓(ya)后(hou)(hou)要脫管(guan)(guan)(guan)定(ding)徑(jing)(jing)(jing)。定(ding)徑(jing)(jing)(jing)機(ji)通過錐形鉆頭高(gao)速(su)旋(xuan)轉入鋼(gang)(gang)胚打(da)孔，形成(cheng)鋼(gang)(gang)管(guan)(guan)(guan)。鋼(gang)(gang)管(guan)(guan)(guan)內徑(jing)(jing)(jing)由定(ding)徑(jing)(jing)(jing)機(ji)鉆頭的(de)外徑(jing)(jing)(jing)長度(du)(du)(du)來確(que)定(ding)。鋼(gang)(gang)管(guan)(guan)(guan)經(jing)定(ding)徑(jing)(jing)(jing)后(hou)(hou)，進(jin)入冷(leng)卻塔中(zhong)(zhong)，通過噴(pen)水(shui)冷(leng)卻，鋼(gang)(gang)管(guan)(guan)(guan)經(jing)冷(leng)卻后(hou)(hou)，就要被矯(jiao)(jiao)直。鋼(gang)(gang)管(guan)(guan)(guan)經(jing)矯(jiao)(jiao)直后(hou)(hou)由傳送(song)(song)帶送(song)(song)至金屬探(tan)傷(shang)機(ji)（或水(shui)壓(ya)實驗）進(jin)行內部探(tan)傷(shang)。若鋼(gang)(gang)管(guan)(guan)(guan)內部有裂紋，氣(qi)泡等問題(ti)，將(jiang)被探(tan)測出。鋼(gang)(gang)管(guan)(guan)(guan)質檢后(hou)(hou)還(huan)要通過嚴格的(de)手(shou)工挑選。鋼(gang)(gang)管(guan)(guan)(guan)質檢后(hou)(hou)，用油(you)漆噴(pen)上編號、規格、生產(chan)批號等。并由吊車吊入倉庫中(zhong)(zhong)。
