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80年代被非常普遍用于精軋前架。目前，高鉻鑄鐵復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的高溫熱處理。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。</p><p style="text-indent:25px">合理選材及采用合適的熱處理方式高質(zhì)量地制造軋輥，可以節(jié)約大量的輥材，降低軋鋼生產(chǎn)成本，同時提高軋輥的質(zhì)量和產(chǎn)量。因此，應(yīng)重視軋輥選材的新動向，從軋鋼的實際條件出發(fā).開發(fā)軋輥的新材質(zhì)，提高軋輥的制造質(zhì)量。軋輥按工作狀態(tài)可分為熱軋輥和冷軋輥，按所起的作用可分為工作輥、中間輥、支承輥，按材質(zhì)可分為鍛輥和鑄輥（冷硬鑄鐵）。通常軋輥的服役條件極其苛刻，工作過程中承受高的交變應(yīng)力、彎曲應(yīng)力、接觸應(yīng)力、剪切應(yīng)力和摩擦力。容易產(chǎn)生磨損和剝落等多種失效形式。軋輥在**終熱處理過程中，對軋輥鋼的淬火和加熱限制在奧氏體中含碳量不超過0.6%的程度。</p><div

style="text-indent:25px">為了降低設(shè)備的沖擊震動，避免軋輥的磨損，并有效延長設(shè)備部件的使用壽命，提升軋輥的質(zhì)量，那么我們就需要做動平衡。刷輥在高速運行中會產(chǎn)生不平衡量，從而會影響到刷輥的質(zhì)量，使用壽命，為了提高刷輥的質(zhì)量，我們就要對其做動平衡檢測，以減小刷輥運行中的振動，減小磨損，延長刷輥使用壽命。軋輥在工作機座中的地位和結(jié)構(gòu)中心地位:機座的其他組件和機構(gòu)都是為裝置、支撐和調(diào)整軋輥以及引導軋件正確地進出軋輥而設(shè)。這是為了避免軋輥的磨損。好的軋輥，其強度、耐磨性和其他各種性能指標間應(yīng)有較優(yōu)的匹配。上海軋輥有哪些</p><p
