無縫鋼管定制加工-無縫鋼管(guan)供應
大(da)部分(fen)流(liu)體(ti)(ti)行業都會使用(yong)無(wu)縫(feng)(feng)(feng)鋼(gang)(gang)管(guan)(guan),無(wu)縫(feng)(feng)(feng)鋼(gang)(gang)管(guan)(guan)的(de)(de)(de)(de)機(ji)(ji)械性能是(shi)(shi)比(bi)較(jiao)強的(de)(de)(de)(de),而(er)且鋼(gang)(gang)管(guan)(guan)的(de)(de)(de)(de)壁比(bi)較(jiao)厚。無(wu)縫(feng)(feng)(feng)鋼(gang)(gang)管(guan)(guan)可(ke)以(yi)(yi)用(yong)來制作各種(zhong)(zhong)各樣(yang)的(de)(de)(de)(de)機(ji)(ji)械零件(jian)和汽車傳動軸,結構用(yong)無(wu)縫(feng)(feng)(feng)鋼(gang)(gang)管(guan)(guan),也可(ke)以(yi)(yi)在自行車的(de)(de)(de)(de)車架上使用(yong),是(shi)(shi)一(yi)(yi)種(zhong)(zhong)可(ke)以(yi)(yi)用(yong)于建筑行業和機(ji)(ji)械行業的(de)(de)(de)(de)材料。無(wu)縫(feng)(feng)(feng)鋼(gang)(gang)管(guan)(guan)就是(shi)(shi)一(yi)(yi)種(zhong)(zhong)沒有縫(feng)(feng)(feng)隙的(de)(de)(de)(de)鋼(gang)(gang)管(guan)(guan)。無(wu)縫(feng)(feng)(feng)鋼(gang)(gang)管(guan)(guan)一(yi)(yi)般是(shi)(shi)沒有中空(kong)截(jie)面和周邊縫(feng)(feng)(feng)隙的(de)(de)(de)(de),是(shi)(shi)一(yi)(yi)種(zhong)(zhong)長(chang)度比(bi)較(jiao)長(chang)的(de)(de)(de)(de)鋼(gang)(gang)材,這種(zhong)(zhong)鋼(gang)(gang)材主要用(yong)于運(yun)輸液體(ti)(ti),是(shi)(shi)一(yi)(yi)種(zhong)(zhong)運(yun)輸流(liu)體(ti)(ti)的(de)(de)(de)(de)管(guan)(guan)道(dao)。
無(wu)(wu)縫(feng)鋼(gang)管(guan)是用(yong)鋼(gang)錠(ding)或(huo)(huo)實心管(guan)坯經穿(chuan)孔制成毛管(guan),然后經熱軋、冷軋或(huo)(huo)冷撥制成。無(wu)(wu)縫(feng)鋼(gang)管(guan)在我(wo)國(guo)鋼(gang)管(guan)業(ye)中具有重(zhong)要的(de)地位。據不完全統(tong)計(ji),我(wo)國(guo)現有無(wu)(wu)縫(feng)管(guan)生產企業(ye)約240多家,無(wu)(wu)縫(feng)鋼(gang)管(guan)機組約250多套,年產能(neng)力約450多萬噸。從口徑看,>Φ76的(de),占35%,>Φ159-650的(de),占25%。
從(cong)品種看,一般用途管(guan)(guan)(guan)(guan)190萬(wan)噸(dun),占(zhan)54%;石(shi)油管(guan)(guan)(guan)(guan)76萬(wan)噸(dun),占(zhan)5。7%;液(ye)壓支柱、精密管(guan)(guan)(guan)(guan)15萬(wan)噸(dun),占(zhan)4。3%;不銹管(guan)(guan)(guan)(guan)、軸(zhou)承管(guan)(guan)(guan)(guan)、汽車管(guan)(guan)(guan)(guan)共5萬(wan)噸(dun),占(zhan)1。4%。軋(ya)制無縫管(guan)(guan)(guan)(guan)的原料是(shi)圓(yuan)管(guan)(guan)(guan)(guan)坯(pi),圓(yuan)管(guan)(guan)(guan)(guan)胚(pei)要經過切割(ge)機的切割(ge)加工(gong)成長度約為(wei)1米(mi)的坯(pi)料,并經傳送(song)帶(dai)送(song)到熔爐內(nei)加熱。
鋼坯被送入熔爐(lu)內(nei)加熱(re),溫度大(da)約為1200攝(she)氏度。爐(lu)內(nei)溫度控制是關鍵性的問題。圓管坯出(chu)爐(lu)后(hou)(hou)要經過壓力穿(chuan)(chuan)孔(kong)機進行(xing)穿(chuan)(chuan)空。一般較常(chang)見的穿(chuan)(chuan)孔(kong)機是錐形(xing)輥穿(chuan)(chuan)孔(kong)機,這種穿(chuan)(chuan)孔(kong)機生產效率高,產品質量好(hao),穿(chuan)(chuan)孔(kong)擴徑量大(da),可穿(chuan)(chuan)多種鋼種。穿(chuan)(chuan)孔(kong)后(hou)(hou),圓管坯就(jiu)先后(hou)(hou)被三輥斜(xie)軋、連(lian)軋或擠壓。
擠壓后要脫管(guan)定徑。定徑機(ji)通過(guo)錐形鉆頭高速旋轉入鋼胚打孔,形成鋼管(guan)。鋼管(guan)內徑由(you)定徑機(ji)鉆頭的外徑長(chang)度來確定。
