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(shí)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(dòng)向，從軋鋼的實(shí)際條件出發(fā).開(kāi)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(guò)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。上海軋輥公司有哪些</p></p><br
