style="text-indent:25px">一般情況下軋輥大部分制造殘余應(yīng)力會(huì)在熱處理過(guò)程中消除，并且會(huì)隨著軋輥的存放時(shí)間延長(zhǎng)而逐漸消除，因此新軋輥存放一段時(shí)間再使用，能夠降低斷輥風(fēng)險(xiǎn)。避免較大機(jī)械應(yīng)力的方法主要是避免過(guò)冷鋼。降低組織應(yīng)力的方法是通過(guò)熱處理將輥身工作層殘余奧氏體含量控制在小于5%以下。減小熱應(yīng)力的辦法是在軋鋼過(guò)程中對(duì)軋輥進(jìn)行良好的冷卻。制造殘余應(yīng)力，機(jī)械應(yīng)力，組織應(yīng)力和熱應(yīng)力是造成高鉻鋼軋輥斷裂的主要原因，良好的熱處理，軋制條件和冷卻可以有效防治高鉻鋼軋輥斷裂。生產(chǎn)中要降低設(shè)備的沖擊震動(dòng)，避免軋輥的磨損。上海軋輥制造商</p><p
