style="text-indent:25px">軋輥是使（軋材）金屬產(chǎn)生塑性變形的工具，是決定軋機效率和軋材質(zhì)量的重要消耗部件。軋輥是軋鋼廠軋鋼機上的重要零件，利用一對或一組軋輥滾動時產(chǎn)生的壓力來軋碾鋼材。它主要承受軋制時的動靜載荷，磨損和溫度變化的影響。軋輥分類。軋輥種類很多，常用的軋輥品種有鑄鋼軋輥、鑄鐵軋輥和鍛造軋輥三大類。在型材軋機上還有少量硬質(zhì)合金軋輥。成型方法：鑄造軋輥是指將冶煉鋼水或熔煉鐵水直接澆注成型制造的軋輥。鑄造軋輥按材質(zhì)又可分為鑄鋼軋輥和鑄鐵軋輥兩類；</p><p style="text-indent:25px">軋輥車間主要依靠磨床渦流探傷設(shè)備、操作人員觀察和軋輥管理人員使用磁粉探傷或超聲波探傷儀器來監(jiān)測軋輥存在的裂紋?，F(xiàn)在一般都采用自動渦流探傷與手動超聲波檢測結(jié)合進行，更加降低了軋輥缺陷影響的幾率。為磨削出合格的軋輥提供了保障。常見的探傷方法　　常見軋輥探傷方法軋輥的探傷方法主要有以下幾種：磁粉探傷、滲透著色探傷、渦流探傷、超聲波探傷。下面逐一進行介紹。1、磁粉探傷　　磁粉探傷技術(shù)主要被用來測定軋輥輥身表面的裂紋和在輥頸區(qū)域的疲勞裂紋、過度的周期負荷或隨后產(chǎn)生的正常腐蝕。軋輥的工作條件是使用時又進一步受到了各種周期應(yīng)力的作用。</p><div

style="text-indent:25px">實際的軋輥生產(chǎn)表明，高鉻鑄鐵軋輥有較好的抗熱裂性能，原因是軋輥表面生成一層致密且有韌性的鉻的氧化膜，能減少熱裂紋的數(shù)量和深度。因此，高鉻鑄鐵輥在20世紀(jì)80年代被非常普遍用于精軋前架。目前，高鉻鑄鐵復(fù)合軋輥已普遍用作熱軋帶 (鋼)連軋機，粗軋和精軋前段工作輥、寬中厚板；粗軋和精軋工作輥及小型型鋼和棒材軋機精軋輥等。高鉻鑄鐵軋輥的熱處理有兩種形式，一是低于臨界轉(zhuǎn)變溫度的亞臨界熱處理，另一種是高于臨界點Ａ3的高溫?zé)崽幚?。高鉻軋輥表面材料的珠光體基體，希望具有極細的片間距，并在基體上有大量彌散分布的二次碳化物，要求有盡量低的殘余奧氏體和殘余應(yīng)力，所以一般選用后一種形式的熱處理，具體為正火加回火。冷軋輥主要失效形式包括劃傷、粘輥和剝落等。上海軋輥品牌推薦</p><p style="text-indent:25px">軋輥常用的熱處理類型：去應(yīng)力退火、等溫球化退火、擴散退火、正火、回火、淬火、深冷處理。上海軋輥品牌推薦</p><p style="text-indent:25px">對熱軋輥來說，輥面不允許出現(xiàn)裂紋，表面裂紋缺陷容易造成應(yīng)力集中，加速擴展而使軋輥失效。熱疲勞裂紋主要起因于周期**變熱應(yīng)力，嚴(yán)重情況下，裂紋擴展可能造成輥面剝落，甚至斷輥。冷軋輥主要失效形式包括劃傷、粘輥和剝落等。冷軋輥輥身表面應(yīng)有高而均勻的硬度，其優(yōu)劣表現(xiàn)在輥身工作層的耐磨性，即耐粗糙性。熱軋工作輥進行的熱處理一般有鍛后熱處理和調(diào)質(zhì)。鍛后熱處理的主要目的是消除鍛后應(yīng)力，細化晶粒，改善切削性能。鍛后熱處理還有擴氫作用。上海軋輥品牌推薦</p><p
