style="text-indent:25px">冷軋工作輥的熱處理一般有鍛后熱處理，調(diào)質(zhì)和表面淬火。鍛后熱處理鍛后熱處理的目的是降低硬度，消除殘余應(yīng)力，同時(shí)還改善組織，得到細(xì)粒珠光體，消除網(wǎng)狀碳化物。鍛后熱處理還有擴(kuò)氫作用。擴(kuò)氫時(shí)間視鋼錠氫含量而定，一般認(rèn)為[H]≤2×10-4%時(shí)，可取消擴(kuò)氫處理。調(diào)質(zhì)：調(diào)質(zhì)的目的是為表面淬火提供組織準(zhǔn)備，使輥頸和輥心得到強(qiáng)韌性配合良好的粒狀珠光體組織，獲得良好的綜合力學(xué)性能，以承受激烈的表面淬火。表面淬火：表面淬火使工作輥獲得高硬化層。上海軋輥質(zhì)量</p><p
