二是微粒之間必須碰撞接觸，才能進(jìn)行傳導(dǎo)傳熱。因此當(dāng)固體內(nèi)存在大量孔隙時(shí)，傳導(dǎo)傳熱便大大削弱，加熱爐常用的隔熱材料就是根據(jù)這一原理制成的；（三)對(duì)流熱交換是由于流體作宏觀運(yùn)動(dòng)時(shí)，在接觸過程中實(shí)現(xiàn)熱能從高溫到低溫的轉(zhuǎn)移。故這種傳熱方式的媒介只能是液體（包括流動(dòng)的異型管鋼坯金屬熔體）和氣體。對(duì)流熱交換可以發(fā)生在流體與固體表面之間，也可以發(fā)生在流體內(nèi)部。不銹鋼異型管的作用:鉻,決定不銹鋼異型管性屬的元素只有一種，這就是鉻，每種不銹鋼都含有一定數(shù)量的鉻。鉻之所以成為決定不銹鋼性能的主要元素，根本的原因是向鋼中添加鉻作為合金元素以后，促使其內(nèi)部的矛盾運(yùn)動(dòng)向有利于抵抗腐蝕破壞的方面發(fā)展。在異型管等結(jié)構(gòu)鋼和工具鋼中，鉻能顯著提度、硬度和耐磨性，但同時(shí)降低塑性和韌性。鉻又能提高鋼的抗氧化性和耐腐蝕性，因而是不銹鋼、耐熱鋼的重要合金元素。 # 鎳是優(yōu)良的耐腐蝕材料，也是合金鋼的重要合金化元素。鎳在鋼中是形成奧氏體的元素，但低碳鎳鋼要獲得純奧氏體組織，含鎳量要達(dá)到24％；而只有含鎳27％時(shí)才使鋼在某些介質(zhì)中的耐腐蝕性能顯著改變。所以鎳不能單獨(dú)構(gòu)成不銹鋼，但是鎳與鉻同時(shí)存在于不銹鋼異型管中時(shí)，含鎳的不銹鋼卻具有許多可貴的性能。但由于鎳是較稀缺的資源，故應(yīng)盡量采用其他合金元素代用鎳鉻鋼。 ======================================================= 錳的作用不在于形成奧氏體，而是在于它降低鋼的臨界淬火速度，在冷卻時(shí)增加奧氏體的穩(wěn)定性，抑制奧氏體的分解，使高溫下形成的奧氏體得以保持到常溫。在提高鋼的耐腐蝕性能方面錳的作用不大，這是因?yàn)殄i對(duì)提高鐵基固溶體的電極電位的作用不大，形成的氧化膜的防護(hù)作用也很低。錳在不銹鋼異型管中穩(wěn)定奧氏體的作用約為鎳的二分之一，并且作用的程度比鎳還要大。

# 異型無縫鋼管按照生產(chǎn)方法不同可分為熱軋管、冷軋管、冷拔管、擠壓管，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)檢查并表面缺陷，截成所需長(zhǎng)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。

class="khcont4">異型管生銹處理辦法：（一）附著排氣中有害成分導(dǎo)致的生銹，在工場(chǎng)地帶，或市街地交通量繁多的環(huán)境下，不銹鋼異型管外表很簡(jiǎn)略遭到污染，有時(shí)也會(huì)出現(xiàn)小斑駁的生銹。這些情況大多是遭到轎車、冷暖氣機(jī)所排氣、或工廠排煙中所含有害成分影響下所導(dǎo)致的。此刻，污染較細(xì)微時(shí)，可用中性清潔劑或肥皂水，即可徹底清潔潔凈，但嚴(yán)峻時(shí)則不是簡(jiǎn)略能處理了。此情況下，則選用前項(xiàng)1中一樣的修理辦法才能鏟除潔凈。在這種環(huán)境中盡可能每年2-3次外表性的定時(shí)打掃作業(yè)，至少也肯定須要做一次定時(shí)清潔。（二）附著清潔液導(dǎo)致的生銹，若用中性清潔劑無法鏟除潔凈時(shí)，則運(yùn)用清潔液來鏟除。（三）外表保護(hù)膜導(dǎo)致的污染，運(yùn)用海綿、布沾上水溶性的中性清潔劑、或酒精來擦洗。假如依然無效時(shí)，則運(yùn)用減弱劑、輕油精來鏟除。清潔后再用清水將不銹鋼異型管徹底沖刷潔凈。（四）受異種金屬附著而生銹，因鐵粉等導(dǎo)致的“順便生銹”或景象不太嚴(yán)峻時(shí)，可用海綿或布、加上中性清潔劑或肥皂水，來擦洗即可很簡(jiǎn)略地鏟除銹。然后再用清水沖刷，留意不可讓洗液留在上面。這種程度的生銹鏟除，只需即時(shí)做鏟除作業(yè)不只保護(hù)簡(jiǎn)略，更有作用，而且鏟除費(fèi)用也很廉價(jià)。但不管它，不久后即構(gòu)成氫氧化鐵、氧化鐵、亞硫酸鐵等混合物，并出現(xiàn)荼褐色的嚴(yán)峻生銹狀況。此種情況下，可用市道銷售的不銹鋼用清潔液或15℅的稀釋等徹底的鏟除潔凈。但是也有不掉的銹，同時(shí)多少也會(huì)損害不銹鋼面，或損害不銹鋼，此刻則用砂紙或不銹鋼刷子，來研磨擦洗，然后再用清潔液清潔潔凈。（五）因附著鹽份而導(dǎo)致生銹，在海岸區(qū)域等正面受海風(fēng)吹擊，不銹鋼異型管也會(huì)在短期間內(nèi)，就發(fā)生紅銹。而且，比其它區(qū)域生銹的更快。海岸區(qū)域在運(yùn)用不銹鋼異型管時(shí)期望盡可能選用更具有耐蝕性的不銹鋼材質(zhì)，而且盡可能每年做3-4次的定時(shí)清潔。（六）因手垢或?qū)е碌纳P，若用中性清潔劑無法鏟除潔凈時(shí)，則用海綿、布、等沾上有機(jī)溶劑來擦洗。此種辦法，仍無法徹底鏟除時(shí)，再運(yùn)用不銹鋼用清潔液來鏟除。各種清潔辦法做清潔后，有必要再做一次清水沖刷。 # 異型管品種和用途：異型管的品種：凡斷面不是圓形的管材或雖是圓形但沿長(zhǎng)度方向的直徑或壁厚發(fā)生變化的管材統(tǒng)稱為異型管。異型管品種具有如下特點(diǎn)。（1）斷面形狀多樣，品種繁多，目前至少有上萬種之多，大的直徑1.06m，小的直徑僅3mm，應(yīng)用范圍也廣泛。（2）異型管中很大一部分為輕型薄壁管材，屬于經(jīng)濟(jì)斷面鋼材的一部分，可使金屬得到合理的應(yīng)用。用它制造機(jī)器零部件和散熱件可以少切削，這不僅簡(jiǎn)化了加工過程，而且提高經(jīng)濟(jì)效益和生產(chǎn)效率。（3）大多數(shù)異型管造型美觀，表面十分光潔且尺寸。（4）可以采用適當(dāng)?shù)姆椒ǎa(chǎn)各種周期斷面、變斷面和各種帶有縱筋或葉片的異型管材，用于工業(yè)各部門。 # 異型管的用途：從日常生活用品到、的制造、無線電通信、原子能電站和空間技術(shù)等方面都廣泛地使用異型管管材。異型管在自行車、摩托車、拖拉機(jī)、汽車和大型客車的機(jī)構(gòu)部分大量采用壁厚異型管，這種管材斷面系數(shù)大，抗彎、抗扭能力強(qiáng)，表面光潔。重量輕。在無軌電車用變截面管制造集電桿，以為這種異型管具有良好的韌性和性。 # 異型管在我們生活中經(jīng)常會(huì)用到，下面就來為大家介紹下異型鋼管的生產(chǎn)制造方法級(jí)用途。A生產(chǎn)制造方法：1.一般鍋爐管使用溫度在430℃以下，國(guó)產(chǎn)管主要用10號(hào)、20號(hào)碳結(jié)鋼熱軋管或冷拔管制造。2.高壓鍋爐管使用時(shí)經(jīng)常處于高溫和高壓條件，管子在高溫?zé)煔夂退魵獾淖饔孟?，?huì)發(fā)生氧化和腐蝕。要求鋼管具有高的持久強(qiáng)度，高的抗氧化腐蝕性能，并有良好的組織穩(wěn)定性。 B用途：1.一般異型鋼管主要用來制造水冷壁管、沸水管、過熱蒸汽管、機(jī)車鍋爐用的過熱蒸汽管，大、小煙管及拱磚管等。2.高壓異型鋼管主要用來制造高壓和超高壓鍋爐的過熱器管、再熱器管、導(dǎo)氣管、主蒸汽管等。 </div><div id="nrdrhsx" class=imgtipsbox>點(diǎn)擊查看萬盛達(dá)鋼鐵(寧德市柘榮縣分公司)的<a
