1.1、熱軋不銹鋼無縫管一般在自動軋管機(jī)組上生產(chǎn)。實(shí)心管坯經(jīng)檢查并***表面缺點(diǎn)，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。再送至自動軋管機(jī)上繼續(xù)軋制。***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)熱軋無縫鋼管是較先進(jìn)的方法。 </p> <p> <br /> </p> <p> 1.2、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，鋼管在變斷面圓孔槽和不動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。 </p> <p> <br /> </p> <p> 1.3、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，使擠壓件從較小的?？字袛D出。此法可生產(chǎn)直徑較小的鋼管。 </p> <p> <br /> </p> <p> 此類鋼管可以分為不銹鋼無縫鋼管和不銹鋼焊接鋼管（有縫管）兩大類，按照制造工藝的不同可以 </p> <p> <br /> </p><div

很多客戶在挑選材料的時(shí)候都面臨非常多的問題，看著市面上參差不齊的價(jià)格以及相關(guān)問題都得不到**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> 一、以304材質(zhì)為例：在挑選鋼管時(shí)必須確定材質(zhì)達(dá)標(biāo)。 </p> <p> <br /> </p> <p> 1. 從價(jià)格上分析，若304材質(zhì)不銹鋼管甚至低于市場上301材質(zhì)的普遍價(jià)格，要仔細(xì)辨別，很可能是其他材質(zhì)冒充； </p> <p> <br /> </p> <p> 2. 認(rèn)明管面上是否打鋼印材質(zhì)“304”字樣，并要索取廠家質(zhì)量證明書作為憑證； </p> <p> <br /> </p> <p> 3. 可用酸性試劑測試，30秒后材質(zhì)304不變色，201變黑色； </p> <p> <br /> </p> <p> 4. 大批量購買可抽取樣品送至國家**檢測中心進(jìn)行成分化驗(yàn)檢測。 </p> <p> <br /> </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img
