style="text-indent:25px">軋輥在使用中磨損、溫度和輥形的不斷變化。此外，軋制條件經(jīng)常會(huì)出現(xiàn)異常情況。軋輥在使用后冷卻不當(dāng)，也會(huì)受到熱應(yīng)力的損害。所以軋輥除磨損外，還經(jīng)常出現(xiàn)裂紋、斷裂、剝落、壓痕等各種局部損傷和表面損傷。一個(gè)好的軋輥，其強(qiáng)度、耐磨性和其他各種性能指標(biāo)間應(yīng)有較優(yōu)的匹配。這樣，不僅在正常軋制條件下持久耐用，又能在出現(xiàn)某些異常軋制情況時(shí)損傷較小。所以在制造軋輥時(shí)要嚴(yán)格控制軋輥的冶金質(zhì)量或輔以外部措施以增強(qiáng)軋輥的承載能力。合理的輥形、孔型、變形制度和軋制條件也能減小軋輥工作負(fù)荷，避免局部高峰應(yīng)力，延長(zhǎng)軋輥壽命。上海軋輥批發(fā)公司軋輥1.5%～2%Cr鍛鋼的熱處理通常采用淬火加低溫回火。</p><div
