1、熱軋無縫管一般在自動(dòng)軋管機(jī)組上生產(chǎn)。實(shí)心管坯經(jīng)檢查并清理表面缺陷，截成所需長度，在管坯穿孔端端面上定心，然后送往加熱爐加熱，在穿孔機(jī)上穿孔。在穿孔同時(shí)不斷旋轉(zhuǎn)和前進(jìn)，在軋輥和頂頭的作用下，管坯內(nèi)部逐漸形成空腔，稱毛管。再送至自動(dòng)軋管機(jī)上繼續(xù)軋制。之后經(jīng)均整機(jī)均整壁厚，經(jīng)定徑機(jī)定徑，達(dá)到規(guī)格要求。利用連續(xù)式軋管機(jī)組生產(chǎn)熱軋無縫管是較先進(jìn)的方法。 2、若欲獲得尺寸更小和質(zhì)量更好的無縫管，必須采用冷軋、冷拔或者兩者聯(lián)合的方法。冷軋通常在二輥式軋機(jī)上進(jìn)行，圓管在變斷面圓孔槽和不動(dòng)的錐形頂頭所組成的環(huán)形孔型中軋制。冷拔通常在0.5～100T的單鏈?zhǔn)交螂p鏈?zhǔn)嚼浒螜C(jī)上進(jìn)行。 3、擠壓法即將加熱好的管坯放在密閉的擠壓圓筒內(nèi)，穿孔棒與擠壓桿一起運(yùn)動(dòng)，使擠壓件從較小的?？字袛D出。此法可生產(chǎn)直徑較小的圓管。</p><p

1、中厚板機(jī)組：主要生產(chǎn)寬厚板，用于直縫埋弧焊管的生產(chǎn)，直縫埋弧焊管質(zhì)量可靠，普遍應(yīng)用于油氣高壓輸送主干線上。 2、爐卷軋機(jī)：爐卷軋機(jī)包括一架往復(fù)式粗軋機(jī)及一架4輥往復(fù)精軋機(jī)。在精軋機(jī)兩邊的輸送線上安裝了兩臺熱卷軋機(jī)。輸出輥道通常包括一套層流冷卻系統(tǒng)和一個(gè)卷取站。在爐卷軋機(jī)上，不銹鋼沖壓彎頭管件整個(gè)長度上的熱機(jī)械歷史明顯變化，尤其是在微不銹鋼沖壓彎頭管件生產(chǎn)中，將強(qiáng)烈影響精軋機(jī)上產(chǎn)生的再結(jié)晶程度、晶粒長大及析出，并且導(dǎo)致整個(gè)不銹鋼沖壓彎頭管件長度上較終顯微組織和性能的劇烈變化 3、半連續(xù)軋機(jī)：包括1機(jī)架爐卷軋機(jī)及5機(jī)架精軋機(jī)。在半連續(xù)軋機(jī)上，管件在精軋道次所經(jīng)歷的熱軋從管件的一端到另一端實(shí)質(zhì)上是恒定的。在精軋機(jī)上道次間的時(shí)間通常少于3s。直到現(xiàn)在，熱鍍鋅無縫管依然是鋼材防腐蝕方法中較普遍、較有效的工藝措施。佛山熱軋無縫管生產(chǎn)廠家</p><p
