摘　　要：建立了双辊薄带铸轧过程中的铸轧辊传热及热变形三维有限元模型。通过动态模拟计算,得到了铸轧辊在稳定工作条件下的铸轧辊辊套的热辊型分布,发现铸轧辊在转动过程中,辊套内、外表面径向热变形分布呈近似椭圆形,即在一个转动周期中,有两个热变形峰值,而且铸轧辊中间对称部位的径向热变形椭圆长轴与边部径向热变形椭圆长轴不在同一个方向上。The 3-D FE model of the heat transfer and thermal deformation of the casting roll was built. The thermal deformation distribution of the casting roll sleeve shape was obtained through numerical simulation in the steady casting condition. It is found that the radial thermal deformation shape of the inner and outer surface of casting roll sleeve is approximately oval, there are two peaks of the thermal deformation, and the direction of the long axis at the axisymmetric section of the roller is different from that at the side section .
