style="text-indent:25px">為了減少軋輥工藝重淬消耗，提高軋輥的淬硬層深度、接觸疲勞強(qiáng)度、韌性，延長其使用壽命，從20世紀(jì)70年代后期到80年代中期，國內(nèi)外開始研究使用鉻含量在3%～5%的深淬硬層冷軋工作輥鋼。3%鉻冷軋輥不需重淬，且有效淬硬層深度可達(dá)到25～30mm，5%Cr冷軋輥有效淬硬層深度則達(dá)到40mm，其耐磨性和抗事故性能也有明顯提高。在這一階段，國內(nèi)試制了9Cr3MoV鋼，國外一些制造廠也先后開發(fā)推廣了深淬硬層冷軋輥，如美國的3.25%Cr鋼和5%Cr鋼，日本的ＫａｎｔｏｃＲＰ53、ＦＨ13、ＭｎＭＣ3和ＭＣ5等。這些鋼都采用高碳高合金材料，具有良好的硬度和耐磨性，但軋輥淬硬表面脆性大，接觸疲勞壽命低，質(zhì)量不穩(wěn)定，上海軋輥哪個品牌好，上海軋輥哪個品牌好。鑄鐵軋輥的生產(chǎn)中，上海軋輥哪個品牌好，普遍采用消除內(nèi)應(yīng)力退火、石墨化退火、正火和回火等工藝。上海軋輥哪個品牌好</p><div

style="text-indent:25px">軋輥1.5%～2%Cr鍛鋼的比較終熱處理通常采用淬火加低溫回火，常見的淬火方式有感應(yīng)表面淬火和整體加熱淬火。其主要任務(wù)是考慮如何提高軋輥的耐磨性能、抗剝落性能，并提高淬硬層深度，盡量保證軋輥表面組織均勻，改善軋輥表層金屬組織的穩(wěn)定性。從20世紀(jì)70年代開始，隨著軋件合金化程度的提高，**度低合金結(jié)構(gòu)鋼(HSLA)的普遍應(yīng)用，軋件的強(qiáng)度和硬度也隨之增加，對軋輥材料的強(qiáng)度和硬度也提出了更高的要求，國際上普遍開始采用鉻含量約2%的Cr-Mo型或Cr-Mo-V型鋼工作輥，如我國一直使用的9cr2Mo、9Cr2MoV和86CrMov7、俄羅斯的9X2MΦ、西德的86Cr2MoV7、日本的MC2等。上海軋輥哪個品牌好軋輥1.5%～2%Cr鍛鋼的熱處理通常采用淬火加低溫回火。</p><div

?：一般按含碳量分類：含碳極高（1.4～2.4%）的過共析鋼軋輥，俗稱半鋼軋輥，高碳的半鋼軋輥實際已伸入鑄鐵領(lǐng)域；高碳過共析鋼軋輥還有一類為石墨鋼軋輥，其石墨是通過孕育和熱處理獲得的。：鍛鋼軋輥 ?一般按用途分類。?其他采用特殊加工工藝的以外，都直接以材質(zhì)稱呼。如用電渣重熔鑄造坯料鍛壓的軋輥稱為電渣重熔鍛壓軋輥。軋輥的損壞原因：軋機(jī)部件中軋輥的工作條件比較為復(fù)雜。軋輥在制造和使用前的準(zhǔn)備工序中會產(chǎn)生殘余應(yīng)力和熱應(yīng)力。使用時又進(jìn)一步受到了各種周期應(yīng)力的作用，包括有彎曲、扭轉(zhuǎn)、剪力、接觸應(yīng)力和熱應(yīng)力等。這些應(yīng)力沿輥身的分布是不均勻的、不斷變化的，其原因不僅有設(shè)計因素。</p><p style="text-indent:25px">軋輥的耐沖擊：對軋輥還有一些特殊要求，如壓下量大時，要求軋輥有較強(qiáng)的咬入能力，耐沖擊性好；光潔度：軋制薄規(guī)格產(chǎn)品時，則對軋輥的剛性、組織性能均勻性、加工精度以及表面光潔度等要求較嚴(yán)；切削性能：軋制復(fù)雜斷面的型鋼時，還要考慮輥身工作層的切削加工性能等。選用軋輥時，對軋輥的有些性能要求往往是彼此對立的，軋輥購置費和維護(hù)費用又很昂貴，所以應(yīng)充分權(quán)衡技術(shù)和經(jīng)濟(jì)上的利弊，決定用鑄的還是鍛的，合金的還是非合金的，單一材料的還是復(fù)合材料的。軋輥1.5%～2%Cr鍛鋼的**終熱處理通常采用淬火加低溫回火。</p><div
