摘　　要：主要分析了铸轧辊的受力状况。铸轧辊在铝及铝合金板坯铸轧过程中既起冷却作用 ,又起压力加工作用 ,其受力状况极其复杂 ,通过对其受力分析 ,应用数值计算 (有限元法FEM)算出铸轧辊的应力分布 ,对铸轧辊辊套与辊芯配合联结的过盈量大小提供参考标准 ,求出最优点 ,即能满足铸轧中所需的最小结合力 ,又满足最佳应力状态 ,使其改善材料的机械性能 ,延长寿命 ,轧制出合格产品 。The cast roll′s stress field is analysed. The cast roll in working effects on cooling and pressing process. Its stress analysis is complex. By analysing on major stress′s and FEM ,the max stress is on the combining face. Its max tired stress is on roll sheath. By analysing, adjusting amount of interference between roll sheath and roll cone may adjust amount of stress on roll sheath.
