3087無縫鋼管是(shi)用(yong)(yong)鋼(gang)錠或實(shi)心(xin)管(guan)坯(pi)經穿孔制成(cheng)毛管(guan),然(ran)后經熱軋(ya)、冷(leng)(leng)軋(ya)或冷(leng)(leng)撥制成(cheng),3087無(wu)縫(feng)鋼(gang)管(guan)屬鋼(gang)材中的(de)(de)(de)一種(zhong)(zhong)材質,屬優質碳(tan)素結構鋼(gang),大量(liang)的(de)(de)(de)模具生(sheng)產公司會用(yong)(yong)到(dao),做模具鋼(gang)使用(yong)(yong)。無(wu)縫(feng)鋼(gang)管(guan)用(yong)(yong)優質碳(tan)素鋼(gang)或合金鋼(gang)制成(cheng),有熱軋(ya)、冷(leng)(leng)軋(ya)(拔(ba))之分(fen)。焊(han)(han)接鋼(gang)管(guan)是(shi)由卷成(cheng)管(guan)形的(de)(de)(de)鋼(gang)板以對縫(feng)或螺(luo)旋縫(feng)焊(han)(han)接而(er)成(cheng),在制造方法上,又(you)分(fen)為低壓流體(ti)輸送用(yong)(yong)焊(han)(han)接鋼(gang)管(guan)、螺(luo)旋縫(feng)電(dian)(dian)焊(han)(han)鋼(gang)管(guan)、直接卷焊(han)(han)鋼(gang)管(guan)、電(dian)(dian)焊(han)(han)管(guan)等(deng)。無(wu)縫(feng)鋼(gang)管(guan)可(ke)用(yong)(yong)于(yu)各種(zhong)(zhong)液(ye)體(ti)、氣(qi)體(ti)管(guan)道(dao)(dao)等(deng)。焊(han)(han)接管(guan)道(dao)(dao)可(ke)用(yong)(yong)于(yu)輸水管(guan)道(dao)(dao)、煤氣(qi)管(guan)道(dao)(dao)、暖氣(qi)管(guan)道(dao)(dao)等(deng)。從口(kou)徑(jing)看,<φ76的(de)(de)(de),占(zhan)(zhan)35%,<φ159-650的(de)(de)(de),占(zhan)(zhan)25%。從品種(zhong)(zhong)看,一般用(yong)(yong)途管(guan)190萬噸(dun),占(zhan)(zhan)54%;石油管(guan)76萬噸(dun),占(zhan)(zhan)5.7%;液(ye)壓支(zhi)柱(zhu)、精密管(guan)15萬噸(dun),占(zhan)(zhan)4.3%;不(bu)銹管(guan)、軸(zhou)承管(guan)、汽(qi)車管(guan)共(gong)5萬噸(dun),占(zhan)(zhan)1.4%。
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。
