熱軋（擠壓無縫鋼管）：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 </p> <p> <br /> </p> <p> 軋制無縫管的原料是圓管坯，圓管胚要經(jīng)過切割機(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，山西904L不銹鋼無縫管廠家電話地址。燃料為氫氣或乙炔。爐內(nèi)溫度控制是關(guān)鍵性的問題.圓管坯出爐后要經(jīng)過壓力穿孔機(jī)進(jìn)行穿空。一般較常見的穿孔機(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)度來確定。鋼管經(jīng)定徑后，進(jìn)入冷卻塔中，通過噴水冷卻，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，氣泡等問題，將被探測(cè)出，山西904L不銹鋼無縫管廠家電話地址，山西904L不銹鋼無縫管廠家電話地址。鋼管質(zhì)檢后還要通過嚴(yán)格的手工挑選。鋼管質(zhì)檢后，用油漆噴上編號(hào)、規(guī)格、生產(chǎn)批號(hào)等。并由吊車吊入倉庫中。

鉻的作用也是有益的，鉻除對(duì)奧氏體不銹鋼耐蝕性有重要影響外，還能提高該類鋼的抗氧化?？沽蚧涂谷邴}腐蝕等性能。鎳的影響1鎳對(duì)組織的影響鎳是強(qiáng)烈穩(wěn)定奧氏體且擴(kuò)大奧氏體相區(qū)的元素，為了獲得單一的奧氏體組織，當(dāng)鋼中含有低鎳含量約為8%。這便是18-8鉻鎳奧氏體不銹鋼的基本分，奧氏體不銹鋼中，隨著鎳含量的增加，殘余的鐵素體可完全消除，并降低σ相形成的傾向；同時(shí)馬氏體轉(zhuǎn)烴溫度降低，甚至可不出現(xiàn)λ→M相變，但是鎳含量的增加會(huì)降低碳在奧氏體不銹鋼中的溶解度，從而使碳化物析出傾向增強(qiáng)。2鎳對(duì)性能的影響鎳對(duì)奧氏體不銹鋼特別是對(duì)鉻鎳奧氏體不銹鋼力學(xué)性能的影響，主要是由鎳對(duì)奧氏體穩(wěn)定性的影響來決定，在鋼中可能發(fā)生馬氏體轉(zhuǎn)變的鎳含量范圍內(nèi)，隨著鎳含量的增加，鋼的強(qiáng)度降低而塑性提高，具有穩(wěn)定奧氏體組織的鉻鎳奧氏體不銹鋼韌性（包括極低溫韌性）非常優(yōu)良，因而可作為低溫鋼使用，這是眾所周知的，對(duì)于具有穩(wěn)定奧氏體組織的鉻錳奧氏體不銹鋼，鎳的加入可進(jìn)一步改善其韌性。鎳還可降低奧氏體不銹鋼的冷加工硬化傾向，這主要是由于奧氏體穩(wěn)定性增大，減少以至消除了冷加工過程中的馬氏體轉(zhuǎn)變，同時(shí)對(duì)奧氏體本身的冷加工硬化作用不太明顯。山西904L不銹鋼無縫管廠家電話地址</p><p
