　　3087無縫鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)(guan)的原料(liao)是圓管(guan)(guan)(guan)(guan)(guan)(guan)坯(pi)(pi)，圓管(guan)(guan)(guan)(guan)(guan)(guan)胚(pei)要經(jing)過(guo)(guo)切割機(ji)的切割加工成長度(du)約(yue)為1米的坯(pi)(pi)料(liao)，并(bing)經(jing)傳送帶(dai)送到熔爐內(nei)(nei)加熱(re)。鋼(gang)(gang)坯(pi)(pi)被(bei)送入(ru)熔爐內(nei)(nei)加熱(re)，溫度(du)大約(yue)為1200℃。燃料(liao)為氫氣或乙炔(gui)。爐內(nei)(nei)溫度(du)控制是關(guan)鍵(jian)性(xing)的問(wen)題(ti).圓管(guan)(guan)(guan)(guan)(guan)(guan)坯(pi)(pi)出(chu)(chu)爐后(hou)(hou)要經(jing)過(guo)(guo)壓力(li)穿(chuan)(chuan)孔機(ji)進(jin)行穿(chuan)(chuan)空。一般較常見的穿(chuan)(chuan)孔機(ji)是錐形輥(gun)穿(chuan)(chuan)孔機(ji)，這種穿(chuan)(chuan)孔機(ji)生產(chan)效率高，產(chan)品質量好，穿(chuan)(chuan)孔擴徑量大，可穿(chuan)(chuan)多種鋼(gang)(gang)種。穿(chuan)(chuan)孔后(hou)(hou)，圓管(guan)(guan)(guan)(guan)(guan)(guan)坯(pi)(pi)就(jiu)先后(hou)(hou)被(bei)三輥(gun)斜(xie)軋(ya)、連軋(ya)或擠(ji)壓。擠(ji)壓后(hou)(hou)要脫管(guan)(guan)(guan)(guan)(guan)(guan)定(ding)徑。定(ding)徑機(ji)通(tong)過(guo)(guo)錐形鉆頭高速(su)旋(xuan)轉入(ru)鋼(gang)(gang)胚(pei)打孔，形成鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)(guan)。鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)(guan)內(nei)(nei)徑由(you)定(ding)徑機(ji)鉆頭的外徑長度(du)來確(que)定(ding)。鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)(guan)經(jing)定(ding)徑后(hou)(hou)，進(jin)入(ru)冷卻塔中，通(tong)過(guo)(guo)噴水冷卻，鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)(guan)經(jing)冷卻后(hou)(hou)，就(jiu)要被(bei)矯(jiao)直。鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)(guan)經(jing)矯(jiao)直后(hou)(hou)由(you)傳送帶(dai)送至金(jin)屬探(tan)傷(shang)機(ji)(或水壓實驗)進(jin)行內(nei)(nei)部探(tan)傷(shang)。若鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)(guan)內(nei)(nei)部有裂紋(wen)，氣泡等問(wen)題(ti)，將(jiang)被(bei)探(tan)測出(chu)(chu)。鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)(guan)質檢后(hou)(hou)還要通(tong)過(guo)(guo)嚴格(ge)的手工挑選。鋼(gang)(gang)管(guan)(guan)(guan)(guan)(guan)(guan)質檢后(hou)(hou)，用油漆噴上編號、規格(ge)、生產(chan)批號等。并(bing)由(you)吊(diao)車吊(diao)入(ru)倉庫中。
