style="text-indent:25px">鋼軌切面成”工”字形，分為與車輪接觸的軌頭、中間的軌腰及底部的軌底。不同的路線對鋼軌的強度、穩(wěn)定性及耐磨性都有不同的要求。因此鋼軌亦有不同的規(guī)格。一條路線上應該選擇使用那一種，需要考慮經(jīng)濟及技術等因素。而使用帶有加壓控制開關的多嘴環(huán)管加熱器，以及輔助設備帶有陶瓷切割片的鋼筋常溫直角切斷機。當采用氧液化石油氣火焰進行加熱焊接時，需要配備梅花狀噴嘴的多嘴環(huán)管加熱器。鋼軌焊接是一件很重大的事情，它的質(zhì)量要有保證，所以進行鋼軌焊接都要有一定的技術要求。蘇州h型輕軌國際上各個國家都有自己的生產(chǎn)鋼軌的標準，分類方式也不盡相同。</p><div

style="text-indent:25px">鋼軌傷損是指鋼軌在使用過程中，發(fā)生折斷、裂紋及其它影響和限制鋼軌使用性能的傷損。為便于統(tǒng)計和分析鋼軌傷損，需對鋼軌傷損進行分類。根據(jù)傷損在鋼軌斷面上的位置、傷損外貌及傷損原因等分為九類32種傷損，用兩位數(shù)編號分類，十位數(shù)表示傷損的部位和狀態(tài)，個位數(shù)表示造成傷損的原因。鋼軌傷損分類具體內(nèi)容可見“鐵道工務技術手冊（軌道）”。鋼軌折斷是指有下列情況之一者：鋼軌全截面至少斷成兩部分；裂縫已經(jīng)貫通整個軌頭截面或軌底截面；鋼軌頂面上有長大于50mm、深大于10mm的掉塊。鋼軌折斷直接威脅行車安全，應及時更換。鋼軌裂紋是指除鋼軌折斷之外，鋼軌部分材料發(fā)生分離，形成裂紋。鋼軌傷損種類很多，常見的有磨耗、剝離及軌頭核傷、軌腰螺栓孔裂紋等。</p><p style="text-indent:25px">重軌鋼就是鋼軌鋼，是斷面為非對稱工字形大型鋼材。通常是以每米長度的重量來表示其規(guī)格，學成分與力學性能我國的重軌鋼的標準有六個牌號，其中U71、U74等兩個為碳素重軌鋼；U71Cu、U71Mn、U70MnSi、U71MnSiCu等四個為低合金重軌鋼。重軌鋼應具有**度、高韌性、良好的耐磨性、足夠的沖擊性和變形抵抗性等特點。重軌鋼的重量、長度系列各國重軌鋼標準長度不同，重軌的外觀尺寸及質(zhì)量重軌的外觀質(zhì)量主要包括三個方面：重軌各部位尺寸的偏差、重軌的彎曲度和重軌的表面質(zhì)量。隨著鐵路運輸?shù)陌l(fā)展和行車速度的提高，對重軌的尺寸及平直度的要求越來越嚴格精確，尤其要求接頭良好。我國鋼軌的標準長度為12.5m和25.0m兩種。</p><div

style="text-indent:25px">低合金鋼軌是應鐵路應用需求，而逐漸衍生出的耐磨損、抗彎曲、抗脆斷、抗疲憊強，且具有良好焊接性能的，主要用于鐵路鋼軌的**合金材料。什么是低合金鋼軌鋼?鋼軌是鐵路軌道的主要部件，是冶金產(chǎn)品中一個**鋼材品種，鋼軌承受列車的重量和動載，受力復雜，軌面磨耗，軌頭受沖擊，還要受較大的彎曲應力，主要的損傷形式有：磨損主要是上股側(cè)磨和下股壓潰，屈服強度不足引起的波浪磨耗以及韌塑性低導致的脆斷、剝落、掉塊、軌頭劈裂、焊縫裂紋等。所以對鋼軌鋼的基本要求包括：耐磨性、抗壓潰性、抗脆斷性、抗疲憊和良好的焊接性。鋼軌的斷面形狀采用具有較佳抗彎性能的工字形斷面，有軌頭、軌腰以及軌底三部分組成。寧波冷拔導軌型鋼</p><p

style="text-indent:25px">改善列車通過曲線的條件，可采用磨耗型車輪踏面，采用徑向轉(zhuǎn)向架等會降低側(cè)磨的速率。從工務角度來講，應改善鋼軌材質(zhì)，采用耐磨軌，例如高硬稀土軌其耐磨性是普通軌的2倍左右，淬火軌為1倍以上。加強養(yǎng)護維修，設置合適的軌距、外軌超高及軌底坡，增加線路的彈性，在鋼軌側(cè)面涂油等，都可以減小側(cè)面磨耗的效果。波浪形磨耗是指鋼軌頂面上出現(xiàn)的波浪狀不均勻磨耗，實質(zhì)上是波浪形壓潰。波磨會引起很高的輪軌動力作用，加速機車車輛及軌道部件的損壞，增加養(yǎng)護維修費用；此外列車的劇烈振動，會使旅客不適，嚴重時還會威脅到行車安全；波磨也是噪音的來源。我國一些貨運干線上，出現(xiàn)了嚴重的波磨。其發(fā)展速度比側(cè)磨還快，成為換軌的主要原因。寧波冷拔導軌型鋼</p></p><br
