在(zai)不(bu)(bu)銹(xiu)(xiu)鋼(gang)無縫管的(de)生(sheng)(sheng)產(chan)過程中(zhong),不(bu)(bu)同生(sheng)(sheng)產(chan)工(gong)藝生(sheng)(sheng)產(chan)的(de)產(chan)品質量存在(zai)差異。不(bu)(bu)銹(xiu)(xiu)鋼(gang)無縫管的(de)常見(jian)生(sheng)(sheng)產(chan)工(gong)藝有哪些(xie)?
浙江(jiang)不銹(xiu)鋼(gang)(gang)管(guan)(guan)(guan)(guan)廠(chang)家1.熱(re)(re)軋:圓管(guan)(guan)(guan)(guan)坯(pi)-加(jia)(jia)熱(re)(re)-穿(chuan)(chuan)孔(kong)(kong)-三輥(gun)交叉軋制(zhi)(zhi)、連續(xu)軋制(zhi)(zhi)或擠壓(ya)-剝管(guan)(guan)(guan)(guan)-定(ding)徑(jing)(jing)(jing)(或減徑(jing)(jing)(jing))-冷(leng)卻(que)-矯直-水(shui)壓(ya)試驗(yan)(或探(tan)傷)-標記-入庫(ku)-軋制(zhi)(zhi)無縫(feng)鋼(gang)(gang)管(guan)(guan)(guan)(guan)的原(yuan)料(liao)為圓管(guan)(guan)(guan)(guan)坯(pi),圓管(guan)(guan)(guan)(guan)坯(pi)經切(qie)割機(ji)切(qie)割成(cheng)約(yue)1米長的坯(pi)體,坯(pi)體經傳(chuan)送(song)帶送(song)至熔(rong)化爐(lu)(lu)(lu)加(jia)(jia)熱(re)(re)。鋼(gang)(gang)坯(pi)被送(song)入熔(rong)爐(lu)(lu)(lu),在大(da)約(yue)1200攝氏度(du)的溫度(du)下加(jia)(jia)熱(re)(re)。燃料(liao)是氫或乙(yi)炔。爐(lu)(lu)(lu)內溫度(du)控制(zhi)(zhi)是一個關鍵問題。圓管(guan)(guan)(guan)(guan)坯(pi)出爐(lu)(lu)(lu)后(hou),必(bi)須(xu)通過(guo)壓(ya)力穿(chuan)(chuan)孔(kong)(kong)機(ji)使其變空。普通穿(chuan)(chuan)孔(kong)(kong)機(ji)為錐形輥(gun)穿(chuan)(chuan)孔(kong)(kong)機(ji),生(sheng)產效率高(gao),產品質(zhi)量(liang)好,擴徑(jing)(jing)(jing)大(da),能穿(chuan)(chuan)透各種鋼(gang)(gang)種。穿(chuan)(chuan)孔(kong)(kong)后(hou),圓管(guan)(guan)(guan)(guan)坯(pi)通過(guo)三輥(gun)連續(xu)交叉軋制(zhi)(zhi)、連續(xu)軋制(zhi)(zhi)或擠壓(ya)。擠出后(hou),取下管(guan)(guan)(guan)(guan)道并設定(ding)直徑(jing)(jing)(jing)。定(ding)徑(jing)(jing)(jing)機(ji)通過(guo)錐形鉆頭高(gao)速(su)旋轉(zhuan)成(cheng)鋼(gang)(gang)坯(pi)進行沖孔(kong)(kong),形成(cheng)鋼(gang)(gang)管(guan)(guan)(guan)(guan)。鋼(gang)(gang)管(guan)(guan)(guan)(guan)的內徑(jing)(jing)(jing)由(you)定(ding)徑(jing)(jing)(jing)機(ji)鉆頭的外徑(jing)(jing)(jing)長度(du)決定(ding)。鋼(gang)(gang)管(guan)(guan)(guan)(guan)定(ding)型后(hou),進入冷(leng)卻(que)塔中,并用噴水(shui)冷(leng)卻(que)。冷(leng)卻(que)后(hou),鋼(gang)(gang)管(guan)(guan)(guan)(guan)將被拉(la)直。矯直后(hou),鋼(gang)(gang)管(guan)(guan)(guan)(guan)由(you)傳(chuan)送(song)帶送(song)至金屬探(tan)傷儀(或水(shui)壓(ya)試驗(yan))進行內部探(tan)傷。如果鋼(gang)(gang)管(guan)(guan)(guan)(guan)有裂紋、氣泡和其他問題,它們(men)將被檢(jian)測到。質(zhi)量(liang)檢(jian)驗(yan)后(hou),鋼(gang)(gang)管(guan)(guan)(guan)(guan)必(bi)須(xu)嚴格(ge)(ge)手工(gong)挑(tiao)選。鋼(gang)(gang)管(guan)(guan)(guan)(guan)質(zhi)量(liang)檢(jian)驗(yan)合格(ge)(ge)后(hou),對序號(hao)、規格(ge)(ge)和生(sheng)產批號(hao)進行噴漆。用起重機(ji)吊進倉庫(ku)。
2.冷(leng)拉(la)(軋(ya)制(zhi))無(wu)(wu)縫(feng)(feng)鋼(gang)(gang)管(guan)(guan):圓(yuan)管(guan)(guan)坯-加熱(re)-穿孔-鐓頭-退火-酸洗-涂(tu)油(you)(鍍銅)-多道二次冷(leng)拉(la)(冷(leng)軋(ya))-鋼(gang)(gang)坯-熱(re)處理-矯直(zhi)-水(shui)壓試(shi)驗(yan)(探(tan)傷(shang))-標(biao)記-入(ru)庫。冷(leng)拉(la)(軋(ya)制(zhi))無(wu)(wu)縫(feng)(feng)鋼(gang)(gang)管(guan)(guan)的(de)軋(ya)制(zhi)方法比熱(re)軋(ya)(擠壓)無(wu)(wu)縫(feng)(feng)鋼(gang)(gang)管(guan)(guan)更復雜(za)。他(ta)(ta)們(men)生產過程的(de)前三個步(bu)驟基本(ben)相同。不(bu)同之處在于從第四步(bu)開(kai)始,在圓(yuan)管(guan)(guan)坯清空后(hou)(hou),開(kai)始圓(yuan)管(guan)(guan)坯并退火。退火后(hou)(hou),應使(shi)用特(te)殊的(de)酸性(xing)液體進(jin)(jin)行酸洗。酸洗后(hou)(hou),涂(tu)上(shang)油(you)。接著是多道二次冷(leng)拉(la)(冷(leng)軋(ya))和管(guan)(guan)坯,以及特(te)殊熱(re)處理。熱(re)處理后(hou)(hou),必須將(jiang)其(qi)拉(la)直(zhi)。矯直(zhi)后(hou)(hou),鋼(gang)(gang)管(guan)(guan)由傳送帶送至金屬探(tan)傷(shang)儀(或水(shui)壓試(shi)驗(yan))進(jin)(jin)行內(nei)部探(tan)傷(shang)。如果(guo)鋼(gang)(gang)管(guan)(guan)有裂(lie)紋、氣泡和其(qi)他(ta)(ta)問題,它們(men)將(jiang)被檢(jian)(jian)測(ce)到。質(zhi)量檢(jian)(jian)驗(yan)后(hou)(hou),鋼(gang)(gang)管(guan)(guan)必須嚴格(ge)(ge)手工挑選。鋼(gang)(gang)管(guan)(guan)質(zhi)量檢(jian)(jian)驗(yan)合格(ge)(ge)后(hou)(hou),對序號、規格(ge)(ge)和生產批(pi)號進(jin)(jin)行噴漆。用起重機(ji)吊進(jin)(jin)倉庫。
