在(zai)不(bu)銹鋼(gang)(gang)(gang)無縫管的(de)生產(chan)過程(cheng)中，不(bu)同生浙江不(bu)銹鋼(gang)(gang)(gang)管廠家產(chan)工藝生產(chan)的(de)產(chan)品質量(liang)存在(zai)差異。不(bu)銹鋼(gang)(gang)(gang)無縫管的(de)常見生產(chan)工藝有哪(na)些(xie)？

1.熱(re)(re)軋(ya)(ya)：圓管(guan)(guan)(guan)(guan)(guan)(guan)(guan)坯(pi)(pi)(pi)(pi)-加(jia)(jia)熱(re)(re)-穿(chuan)(chuan)(chuan)孔(kong)-三輥(gun)(gun)交叉(cha)(cha)軋(ya)(ya)制(zhi)、連(lian)續(xu)軋(ya)(ya)制(zhi)或(huo)(huo)(huo)擠壓(ya)-剝管(guan)(guan)(guan)(guan)(guan)(guan)(guan)-定(ding)徑(jing)(或(huo)(huo)(huo)減徑(jing))-冷卻(que)-矯(jiao)直(zhi)(zhi)-水(shui)壓(ya)試(shi)驗(yan)(yan)(yan)(yan)(或(huo)(huo)(huo)探(tan)(tan)傷(shang))-標記-入庫-軋(ya)(ya)制(zhi)無縫鋼(gang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)的(de)(de)原料(liao)為圓管(guan)(guan)(guan)(guan)(guan)(guan)(guan)坯(pi)(pi)(pi)(pi)，圓管(guan)(guan)(guan)(guan)(guan)(guan)(guan)坯(pi)(pi)(pi)(pi)經切割機(ji)(ji)(ji)切割成(cheng)(cheng)約1米長的(de)(de)坯(pi)(pi)(pi)(pi)體，坯(pi)(pi)(pi)(pi)體經傳送帶(dai)送至(zhi)熔化(hua)爐(lu)加(jia)(jia)熱(re)(re)。鋼(gang)坯(pi)(pi)(pi)(pi)被(bei)(bei)送入熔爐(lu)，在大(da)約1200攝氏度的(de)(de)溫度下加(jia)(jia)熱(re)(re)。燃料(liao)是氫或(huo)(huo)(huo)乙炔(gui)。爐(lu)內(nei)溫度控制(zhi)是一(yi)個關鍵問題(ti)。圓管(guan)(guan)(guan)(guan)(guan)(guan)(guan)坯(pi)(pi)(pi)(pi)出爐(lu)后(hou)(hou)，必須通(tong)過(guo)壓(ya)力穿(chuan)(chuan)(chuan)孔(kong)機(ji)(ji)(ji)使其變空。普通(tong)穿(chuan)(chuan)(chuan)孔(kong)機(ji)(ji)(ji)為錐形輥(gun)(gun)穿(chuan)(chuan)(chuan)孔(kong)機(ji)(ji)(ji)，生產(chan)效率高，產(chan)品質量好，擴徑(jing)大(da)，能(neng)穿(chuan)(chuan)(chuan)透各種鋼(gang)種。穿(chuan)(chuan)(chuan)孔(kong)后(hou)(hou)，圓管(guan)(guan)(guan)(guan)(guan)(guan)(guan)坯(pi)(pi)(pi)(pi)通(tong)過(guo)三輥(gun)(gun)連(lian)續(xu)交叉(cha)(cha)軋(ya)(ya)制(zhi)、連(lian)續(xu)軋(ya)(ya)制(zhi)或(huo)(huo)(huo)擠壓(ya)。擠出后(hou)(hou)，取下管(guan)(guan)(guan)(guan)(guan)(guan)(guan)道并(bing)(bing)設定(ding)直(zhi)(zhi)徑(jing)。定(ding)徑(jing)機(ji)(ji)(ji)通(tong)過(guo)錐形鉆(zhan)頭高速旋轉成(cheng)(cheng)鋼(gang)坯(pi)(pi)(pi)(pi)進行(xing)沖孔(kong)，形成(cheng)(cheng)鋼(gang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)。鋼(gang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)的(de)(de)內(nei)徑(jing)由定(ding)徑(jing)機(ji)(ji)(ji)鉆(zhan)頭的(de)(de)外徑(jing)長度決定(ding)。鋼(gang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)定(ding)型后(hou)(hou)，進入冷卻(que)塔中，并(bing)(bing)通(tong)過(guo)噴水(shui)冷卻(que)。冷卻(que)后(hou)(hou)，鋼(gang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)將(jiang)被(bei)(bei)拉直(zhi)(zhi)。矯(jiao)直(zhi)(zhi)后(hou)(hou)，鋼(gang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)由傳送帶(dai)送至(zhi)金屬探(tan)(tan)傷(shang)儀(或(huo)(huo)(huo)水(shui)壓(ya)試(shi)驗(yan)(yan)(yan)(yan))進行(xing)內(nei)部探(tan)(tan)傷(shang)。如(ru)果鋼(gang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)有裂紋、氣泡和其他問題(ti)，它(ta)們(men)將(jiang)被(bei)(bei)檢測到。質量檢驗(yan)(yan)(yan)(yan)后(hou)(hou)，鋼(gang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)必須嚴格手工挑選。鋼(gang)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)質量檢驗(yan)(yan)(yan)(yan)合格后(hou)(hou)，對序號、規格和生產(chan)批號進行(xing)噴漆。用起重機(ji)(ji)(ji)吊進倉庫。

2.冷拉(la)(軋(ya)制(zhi))無(wu)縫鋼(gang)管(guan)：圓管(guan)坯(pi)-加熱(re)(re)-穿孔-鐓(dui)頭-退火-酸(suan)洗(xi)-涂油(you)(鍍銅)-多道(dao)二次冷拉(la)(冷軋(ya))-鋼(gang)坯(pi)-熱(re)(re)處(chu)理(li)-矯(jiao)直-水(shui)(shui)壓試驗(yan)(探傷(shang))-標記-入(ru)庫。冷拉(la)(軋(ya)制(zhi))無(wu)縫鋼(gang)管(guan)的(de)軋(ya)制(zhi)方(fang)法比(bi)熱(re)(re)軋(ya)(擠壓)無(wu)縫鋼(gang)管(guan)更復(fu)雜。他們生產過(guo)程(cheng)的(de)前三個步(bu)驟基本(ben)相(xiang)同(tong)。不(bu)同(tong)之(zhi)處(chu)在于從第四步(bu)開始(shi)，在圓管(guan)坯(pi)清空后(hou)，開始(shi)圓管(guan)坯(pi)并退火。退火后(hou)，應使用(yong)特殊的(de)酸(suan)性液體進(jin)行酸(suan)洗(xi)。酸(suan)洗(xi)后(hou)，涂上(shang)油(you)。接溫(wen)州不(bu)銹鋼(gang)管(guan)著是多道(dao)二次冷拉(la)(冷軋(ya))和管(guan)坯(pi)，以及特殊熱(re)(re)處(chu)理(li)。熱(re)(re)處(chu)理(li)后(hou)，必須將(jiang)其拉(la)直。矯(jiao)直后(hou)，鋼(gang)管(guan)由傳送帶送至金屬(shu)探傷(shang)儀(或水(shui)(shui)壓試驗(yan))進(jin)行內部探傷(shang)。如果鋼(gang)管(guan)有裂紋、氣泡和其他問題，它們將(jiang)被檢(jian)測(ce)到。質量檢(jian)驗(yan)后(hou)，鋼(gang)管(guan)必須嚴格手工(gong)挑選(xuan)。鋼(gang)管(guan)質量檢(jian)驗(yan)合格后(hou)，對(dui)序號(hao)、規格和生產批號(hao)進(jin)行噴(pen)漆。用(yong)起重機(ji)吊進(jin)倉庫。

在不銹鋼無(wu)縫(feng)鋼管的生產過程中，選擇合適的生產工(gong)藝是非(fei)常重要的。
