style="text-indent:25px">進(jìn)步鋼軌強(qiáng)度和綜合性能的途徑有哪些?(1)熱處理強(qiáng)化。在碳素鋼或C—Mn鋼軌基礎(chǔ)上采用在線(xiàn)余熱淬火，離線(xiàn)的淬火回火處理或欠速淬火工藝。20世紀(jì)80年代發(fā)展起來(lái)的在線(xiàn)熱處理方式，也叫做全長(zhǎng)淬火工藝，這樣可以有效地節(jié)能省工、投資少，并且其生產(chǎn)周期非常的短。(2)在0.7%～0.75%C鋼中添加Cr、Mn、Mo、Nb等合金元素，獲得980～1250MPa抗拉強(qiáng)度。比較兩種強(qiáng)化方法，熱處理軌表面耐磨，但內(nèi)部較差，耐蝕性不能改善。合金化軌里外質(zhì)量一致，可以考慮改善耐蝕性。</p><p style="text-indent:25px">鋼軌的種類(lèi)及強(qiáng)度以kg/m表示。每米越重的鋼軌所能承受的重量亦越大。常見(jiàn)的鋼軌有以下多種重量： 40kg/m ，50kg/m ，60kg/m 國(guó)內(nèi)有：50kg/m 60kg/m ，75kg/m ，主要線(xiàn)路使用的是60kg/m 或75kg/m的鋼軌。地鐵軌道是重型鋼軌，重型鋼軌知識(shí)：每米公稱(chēng)重量大于30kg的鋼軌?；疖?chē)鋼軌和起重機(jī)軌都屬重軌?；疖?chē)鋼軌：用于鋪設(shè)鐵路，要承受火車(chē)營(yíng)運(yùn)時(shí)的壓力、沖擊載荷和摩擦，要求有足夠的強(qiáng)度和一定的韌性。質(zhì)量要求嚴(yán)格，除保證其化學(xué)成分外，還要求檢驗(yàn)力學(xué)性能、落錘試驗(yàn)和酸浸低倍組織等。生產(chǎn)廠(chǎng)有包鋼、鞍鋼、攀鋼和武鋼等。起重機(jī)軌：即吊車(chē)軌，其高度較低，頭寬及腰厚尺寸較大，只要求檢驗(yàn)化學(xué)成分和抗拉強(qiáng)度。一條路線(xiàn)上應(yīng)該選擇使用什么鋼軌，需要考慮經(jīng)濟(jì)及技術(shù)等因素。</p><div

style="text-indent:25px">鐵軌采用h型鋼，工字鋼的一種。h型鋼屬于高效經(jīng)濟(jì)裁面型材(其它還有冷彎薄壁型鋼、壓型鋼板等)，由于截面形狀合理，它們能使鋼材更高地發(fā)揮效能，提高承載能力。不同于普通工字型的是h型鋼的翼緣進(jìn)行了加寬，且內(nèi)、外表面通常是平行的，這樣可便于用**度螺栓和其他構(gòu)件連接。其尺寸構(gòu)成系列合理，型號(hào)齊全，便于設(shè)計(jì)選用?，F(xiàn)代使用的鋼軌切面成”工”字形，分為與車(chē)輪接觸的軌頭、中間的軌腰及底部的軌底。不同的路線(xiàn)對(duì)鋼軌的強(qiáng)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。鋼軌是鐵路軌道的主要組成部件，它在于引導(dǎo)機(jī)車(chē)車(chē)輛的車(chē)輪前進(jìn)，承受車(chē)輪的巨大壓力，并傳遞到軌枕上。道軌鋼價(jià)位</p><p style="text-indent:25px">鋼軌在電氣化鐵路和自動(dòng)閉塞信號(hào)線(xiàn)路上，鋼軌還可兼作電路導(dǎo)體。道軌鋼價(jià)位</p><p style="text-indent:25px">鋼軌傷損是指鋼軌在使用過(guò)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(jì)和分析鋼軌傷損，需對(duì)鋼軌傷損進(jìn)行分類(lèi)。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(lèi)32種傷損，用兩位數(shù)編號(hào)分類(lèi)，十位數(shù)表示傷損的部位和狀態(tài)，個(gè)位數(shù)表示造成傷損的原因。鋼軌傷損分類(lèi)具體內(nèi)容可見(jiàn)“鐵道工務(wù)技術(shù)手冊(cè)（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(gè)軌頭截面或軌底截面；鋼軌頂面上有長(zhǎng)大于50mm、深大于10mm的掉塊。鋼軌折斷直接威脅行車(chē)安全，應(yīng)及時(shí)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(lèi)很多，常見(jiàn)的有磨耗、剝離及軌頭核傷、軌腰螺栓孔裂紋等。道軌鋼價(jià)位</p></p><br
