class="khcont5">異型管在我們生活中經(jīng)常會用到，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，國產(chǎn)管主要用10號、20號碳結(jié)鋼熱軋管或冷拔管制造。2.高壓鍋爐管使用時經(jīng)常處于高溫和高壓條件，管子在高溫?zé)煔夂退魵獾淖饔孟拢瑫l(fā)生氧化和腐蝕。要求鋼管具有高的持久強度，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。據(jù)統(tǒng)計，2012年全球燃燒化石能源生345億噸二氧化碳，而其中煤炭燃燒產(chǎn)生的二氧化碳多。廉價的天然氣已經(jīng)減少了美國對煤炭的需求量，但是在其他，需求還在上升。在接下來的20多年時間里，上將有數(shù)百萬人口次用上電，按照當(dāng)前的趨勢發(fā)展下去，這些電大部分將來源于煤炭。即使取代煤炭的呼聲再高，煤炭也不可能被取代，至少不可能被馬上取代。異型管結(jié)疤的產(chǎn)生，主要有以下點原因：一、在軋制過程中，由于外界金屬物落在軋件表面上，并被帶入孔型內(nèi)，壓入軋件表面，在異型管表面形成結(jié)疤。這種結(jié)疤是不生根的，無規(guī)律性；二、軋槽刻痕不良，在軋件表面上形成較高的凸塊，再軋時異型管產(chǎn)生周期性的結(jié)疤；三、原料表面處理不當(dāng)，留有尖銳的棱邊或深寬比較大的凹坑，經(jīng)軋制后形成結(jié)疤；四、軋制過程中，軋件在成品孔前某一孔型因故損壞或輥環(huán)破缺，當(dāng)軋件通過該孔型后，表面形成凸塊，在后面的軋制過程中，凸塊被壓入基體并隨軋件延伸，終在異型管成品表面上，產(chǎn)生周期性的生根結(jié)疤；五、軋件在孔型內(nèi)打滑，使金屬堆積于變形區(qū)周圍的表面上，在軋時造成結(jié)疤；六、異型管坯表面有較大的冷濺、翻皮、結(jié)疤等缺陷，當(dāng)用鋼錠一火軋成材時，則在成品表面上產(chǎn)生結(jié)疤。鋼管縮管機在使用前要明確了解縮管機的原理、注意事項和使用方法，才能更好的使用縮管機，下面我們就一起了解下。1、鋼管縮管機原理：通過機械傳動，帶動鋼管旋轉(zhuǎn)，并在鋼管的一端用火焰加熱,當(dāng)達(dá)到一定溫度時，用成型模對加熱的鋼管頭部進(jìn)行趕制，直至達(dá)到所要求的形狀為止。2、鋼管縮管機構(gòu)造：用槽鋼焊一個地盤，動力端裝有電機、減速機、卡頭（卡管子用，可用車床卡盤代替）。另一端安裝支撐座（可打開的），支撐座上外端固定一個加熱環(huán)（8-10個噴嘴，用氣焊靠搶嘴焊在一個銅管環(huán)上）。外邊是一個活動的支架，上面安裝一個合金模具。3、鋼管縮管機使用方法：將管子固定在縮管機上，打開加熱器（環(huán)）。待溫度達(dá)到后，推動合金模具，管頭形狀即達(dá)到要求。整個過程約15分鐘。三角管是用鋼材做原材料所生產(chǎn)的三角形（三邊形鋼管）也稱異型鋼管，其中還有八角管、菱形管、橢圓管，六角管等形狀。三角管是除了圓管以外的其他截面形狀的鋼管的總稱，有焊接異型管和無縫異型管,因為材質(zhì)的關(guān)系,不銹鋼異型管一般為304以上材質(zhì)為多,200、201材質(zhì)硬度強風(fēng)，成型難度加大。三角管廣泛用于各種結(jié)構(gòu)件、工具和機械零部件。和圓管相比，不銹鋼異型管一般都有較大的慣性矩和截面模數(shù)，有較大的抗彎抗扭能力，可以大大減輕結(jié)構(gòu)重量，節(jié)約鋼材。

class="khcont">淺析固渣護(hù)爐的具體操作步驟：傳統(tǒng)轉(zhuǎn)爐主要的護(hù)爐方法以補爐、噴補及濺渣護(hù)爐為主。護(hù)爐成本較高，護(hù)爐效果不佳，無法確保轉(zhuǎn)爐爐型的穩(wěn)定運行，且每次補爐需要安排較長時間，影響轉(zhuǎn)爐作業(yè)率，增加了生產(chǎn)組織的難度。同時濺渣護(hù)爐由于過程控制存在波動及階段生產(chǎn)節(jié)奏緊張造成濺渣時間不足，護(hù)爐效果較差。而采取固渣護(hù)爐的方法可以節(jié)約靜態(tài)護(hù)爐時間，有效保證靜態(tài)護(hù)爐效果。還可以通過穩(wěn)定轉(zhuǎn)爐入爐條件，提高轉(zhuǎn)爐終點控制及一次拉碳率，鞏固過程護(hù)爐效果。而且通過確保良好的終渣狀態(tài)濺渣護(hù)爐效果，大幅度降低轉(zhuǎn)爐護(hù)爐成本及爐齡，提高轉(zhuǎn)爐作業(yè)率。異型管的固渣護(hù)爐具體操作步驟是：1.倒渣面固渣爐次終點控制按照w(C)≥0.07%，爐渣R為2.7-3.2、w(MgO)≥6%控制；2.固渣前大面爐次倒?fàn)t、出鋼搖爐不得過低，盡量保持一定渣量，如終點w(C)＜0.07%，適當(dāng)減少留渣量；3.將爐體搖至與平臺平面夾角約30-45°，緩慢加入1.0－1.5t鐵塊；4.直接搖至爐口低于平臺平面夾角約20-30°，使鐵塊迅速均勻平鋪后，將爐口搖到與平臺夾角基本水平。此過程中，我們要注意兩個要點：（一）終點碳合適，渣量小，終渣粘。搖爐過程爐長注意觀察異型管渣量，如爐渣黏度適宜，加入鐵塊搖爐后不濺渣，靜置2-3min后先加廢鋼再兌鐵。生產(chǎn)過程中優(yōu)先保證濺渣護(hù)爐，利用生產(chǎn)間隙組織固渣護(hù)爐，在前后大面出現(xiàn)虧料時采取靜態(tài)護(hù)爐措施。轉(zhuǎn)爐前大面優(yōu)先使用連續(xù)的固渣護(hù)爐，原則上不安排靜態(tài)護(hù)爐時間，耳軸及爐冒位置主要采取濺渣護(hù)爐、后大面一般采取靜態(tài)護(hù)爐，可實現(xiàn)爐型穩(wěn)定控制。（二）終點碳低，渣量大，終渣稀。搖爐過程爐長注意觀察爐內(nèi)渣量及爐渣狀態(tài)，如爐渣過稀，為了保證前大面固渣后平整，同時確保兌鐵時不產(chǎn)生劇烈噴濺反應(yīng)，應(yīng)從爐口將稀渣倒出部分后搖到零位，采用低位濺渣，異型管濺渣時不得加入任何渣料，濺渣后再搖至爐口低于平臺平面夾角約20-30°，使鐵塊迅速均勻平鋪后，將爐口搖到與平臺夾角基本水平，靜置2-3min后先加廢鋼再兌鐵。淺析異型管冷熱兩種鍍鋅工藝；冷鍍鋅也叫電鍍鋅，是利用電解設(shè)備將管件經(jīng)過除油、酸洗、后放入成分為鋅鹽的溶液中，并連接電解設(shè)備的負(fù)極，在異型管件的對面放置鋅版，連接在電解設(shè)備的正極接通電源，利用電流從正極向負(fù)極的定向移動就會在管件上沉積一層鋅，冷鍍管件是先加工后鍍鋅。而熱鍍鋅也叫熱浸鋅和熱浸鍍鋅，是一種有效的金屬防腐方式，主要用于各行業(yè)的金屬結(jié)構(gòu)設(shè)施上。是將除銹后的鋼件浸入500℃左右融化的鋅液中，使異型管鋼構(gòu)件表面附著鋅層，從而起到防腐的目的。對于異型管生產(chǎn)來說，兩種鍍鋅方式各有利弊，下面我們就做一個比較分析：（一）表面光滑度：冷鍍鋅異型管外表比熱鍍鋅的更加光滑好看；（二）防腐蝕性：熱鍍鋅是冷鍍鋅的幾十倍，如果異型管放置于普通環(huán)境下，其熱鍍鋅防銹層可保持50年以上而不必修補；（三）作業(yè)方式：熱鍍鋅是在450－480度熔融的鋅液中鍍鋅，而冷鍍鋅是在常溫下通過電鍍或者其他方法鍍鋅。（四）鍍鋅層厚度：熱鍍鋅厚度遠(yuǎn)遠(yuǎn)大于冷鍍鋅，并且鍍鋅層會形成一種特別的冶金結(jié)構(gòu)，這種結(jié)構(gòu)能承受在運送及使用時受到機械損傷；（五）附著力：冷鍍鋅附著力不如熱鍍鋅。熱鍍鋅層與鋼材間是冶金結(jié)合，成為鋼表面的一部份，因此異型管鍍層持久性更加可靠；（六）成本費用：熱鍍鋅價格遠(yuǎn)高于冷鍍鋅，但是熱鍍鋅防銹的費用又比其他漆料涂層的費用低；（七）鍍鋅位置：冷鍍鋅可以只鍍一面，熱鍍鋅必須內(nèi)外全鍍。也正是因為全鍍所以即使在凹陷處、尖角及隱藏處都能受到保護(hù)；（八）環(huán)境保護(hù)：絕大多數(shù)冷鍍鋅異型管的溶劑和稀釋劑內(nèi)不含甲苯、類、鹵代烴等毒性大的有機溶劑，所以對減少三廢、降低能耗，提高環(huán)境保護(hù)的社會效益的作用更加明顯。

class="khcont">矩形鋼管按生產(chǎn)方法可分為兩大類：無縫矩形鋼管和有縫矩形鋼管,有縫矩形鋼管簡稱為直縫矩形鋼管。無縫矩形鋼管按生產(chǎn)方法可分為：熱軋無縫管、冷拔管、精密矩形鋼管、熱擴管、冷旋壓管和擠壓管等。無縫矩形鋼管用優(yōu)質(zhì)碳素鋼或合金鋼制成，有熱軋、冷軋（拔）之分。焊接矩形鋼管因其焊接工藝不同而分為爐焊管、電焊（電阻焊）管和自動電弧焊管，因其焊接形式的不同分為直縫焊管和螺旋焊管兩種，因其端部形狀又分為圓形焊管和異型（方、扁等）焊管。焊接矩形鋼管是由卷成管形的鋼板以對縫或螺旋縫焊接而成，在制造方法上，又分為低壓流體輸送用焊接矩形鋼管、螺旋縫電焊矩形鋼管、直接卷焊矩形鋼管、電焊管等。無縫矩形鋼管可用于各種行業(yè)的液體氣壓管道和氣體管道等。焊接管道可用于輸水管道、煤氣管道、暖氣管道、電器管道等。 # 影響異型管壁厚等級的因素：腐蝕余量是考慮因介質(zhì)對異型管的腐蝕而造成的管道壁厚減薄，從而增加的管道壁厚值。它的大小直接影響到壁厚的取值，或者說直接影響到壁厚等級的確定。許多的工程公司或設(shè)計院通常都將腐蝕余量分為四級：無腐蝕余量，對一般的不銹鋼管道多取該值；1.6mm腐蝕余量，對于腐蝕不嚴(yán)重的碳素鋼和鉻鉬鋼多取該值；3.2mm腐蝕余量，對于腐蝕比較嚴(yán)重的碳素鋼和鉻鉬鋼管道多取該值；加強級腐蝕余量，對于有固體顆粒沖刷等特殊情況下的管道，根據(jù)實際情況確定其具體值。 # 六角鋼管一般用于機械加工零部件，這種鋼大多用于制造心部強度要求較高，表面承受磨損、截面在30mm以下的或形狀復(fù)雜而負(fù)荷不大的滲碳零件(油淬)，如：機床變速箱齒輪、齒輪軸、凸輪、蝸桿、活塞銷、爪形離合器等；對熱處理變形小和高耐磨性的零件，滲碳后應(yīng)進(jìn)行高頻表面淬火，如模數(shù)小于3的齒輪、軸、花鍵軸等。此鋼也可在調(diào)質(zhì)狀態(tài)下使用，用于制造工作速度較大并承受中等沖擊負(fù)荷的零件，這種鋼還可用作低碳馬氏體淬火用鋼，更進(jìn)一步增加鋼的屈服強度和抗拉強度(約增加1.5～1.7倍)。 # 異型管在進(jìn)行熱處理時，應(yīng)該注意避免加熱缺陷。過燒：加熱溫度過高，不僅引起奧氏體晶粒粗大，而且晶界局部出現(xiàn)氧化或熔化，導(dǎo)致晶界弱化，稱為過燒。鋼過燒后性能嚴(yán)重惡化，淬火時形成龜裂。過燒組織無法恢復(fù)，只能報廢。因此在工作中要避免過燒的發(fā)生。氫脆：度異型管在富氫氣氛中加熱時出現(xiàn)塑性和韌性降低的現(xiàn)象稱為氫脆。出現(xiàn)氫脆的工件通過除氫處理也能氫脆，采用真空、低氫氣氛或惰性氣氛加熱可避免氫脆。脫碳：鋼在加熱時，表層的碳與介質(zhì)中的氧、氫、二氧化碳及水蒸氣等發(fā)生反應(yīng)，降低了表層碳濃度稱為脫碳，脫碳鋼淬火后表面硬度、疲勞強度及耐磨性降低，而且表面形成殘余拉應(yīng)力易形成表面網(wǎng)狀裂紋。
