熱軋（擠壓無(wú)縫鋼管）：圓管坯→加熱→穿孔→三輥斜軋、連軋或擠壓→脫管→定徑（或減徑）→冷卻→矯直→水壓試驗(yàn)（或探傷）→標(biāo)記→入庫(kù) </p> <p> <br /> </p> <p> 軋制無(wú)縫管的原料是圓管坯，圓管胚要經(jīng)過(guò)切割機(jī)的切割加工成長(zhǎng)度約為1米的坯料，并經(jīng)傳送帶送到熔爐內(nèi)加熱。鋼坯被送入熔爐內(nèi)加熱，溫度大約為1200攝氏度。燃料為氫氣或乙炔。爐內(nèi)溫度控制是關(guān)鍵性的問(wèn)題.圓管坯出爐后要經(jīng)過(guò)壓力穿孔機(jī)進(jìn)行穿空。一般較常見(jiàn)的穿孔機(jī)是錐形輥穿孔機(jī)，這種穿孔機(jī)生產(chǎn)效率高，產(chǎn)品質(zhì)量好，穿孔擴(kuò)徑量大，可穿多種鋼種。穿孔后，圓管坯就先后被三輥斜軋、連軋或擠壓。擠壓后要脫管定徑。定徑機(jī)通過(guò)錐形鉆頭高速旋轉(zhuǎn)入鋼胚打孔，形成鋼管。鋼管內(nèi)徑由定徑機(jī)鉆頭的外徑長(zhǎng)度來(lái)確定。鋼管經(jīng)定徑后，進(jìn)入冷卻塔中，通過(guò)噴水冷卻，鋼管經(jīng)冷卻后，就要被矯直。鋼管經(jīng)矯直后由傳送帶送至金屬探傷機(jī)（或水壓實(shí)驗(yàn)）進(jìn)行內(nèi)部探傷。若鋼管內(nèi)部有裂紋，氣泡等問(wèn)題，將被探測(cè)出。鋼管質(zhì)檢后還要通過(guò)嚴(yán)格的手工挑選。鋼管質(zhì)檢后，云南2520不銹鋼無(wú)縫管廠家直供，用油漆噴上編號(hào)、規(guī)格，云南2520不銹鋼無(wú)縫管廠家直供，云南2520不銹鋼無(wú)縫管廠家直供、生產(chǎn)批號(hào)等。并由吊車(chē)吊入倉(cāng)庫(kù)中。

很多客戶在挑選材料的時(shí)候都面臨非常多的問(wèn)題，看著市面上參差不齊的價(jià)格以及相關(guān)問(wèn)題都得不到**終的解決辦法，江蘇進(jìn)百洪再這里給大家分享一些技巧，以至于再后期挑選成品的時(shí)候提高產(chǎn)品性價(jià)比； </p> <p> <br /> </p> <p> 二、軋制管中經(jīng)常會(huì)出現(xiàn)內(nèi)重皮、麻點(diǎn)、和軋制青線，一般情況下這些無(wú)法避免，也基本不影響使用，但在選購(gòu)時(shí)一定要選擇盡量少的，特別是檢查內(nèi)表面。 </p> <p> 三、選購(gòu)時(shí)應(yīng)選擇經(jīng)質(zhì)量技術(shù)監(jiān)督局評(píng)定的***產(chǎn)品。在客戶中有長(zhǎng)時(shí)間使用見(jiàn)證和良好口碑是**直接有效的選購(gòu)方法。 </p> <p> 四、觀看外表面和管內(nèi)壁的顏色是否光亮平滑、厚度是否均勻或有粗糙現(xiàn)象。一般焊管此項(xiàng)基本不用檢查，而不銹鋼無(wú)縫管是采用冷拔或熱軋方式生產(chǎn)的，在生產(chǎn)過(guò)程中操作不當(dāng)容易產(chǎn)生厚度不均勻、管面有裂紋等現(xiàn)象，而表面粗糙一般是無(wú)縫管未進(jìn)行拋光處理，若對(duì)外觀無(wú)特別要求不影響使用。 </p> <p> 五、在挑選不銹鋼無(wú)縫管之前需考慮到不銹鋼管的用途以及使用環(huán)境。如：裝潢用一般使用焊管，流體輸送一般用無(wú)縫管，醫(yī)療或廚房要使用衛(wèi)生級(jí)不銹鋼管，承壓使用厚壁管；一般室內(nèi)采用200系列材質(zhì)即可，室外需使用304等材質(zhì)，而在酸堿性地方或沿海地區(qū)一般要使用316以上材質(zhì)。 </p> <p>
