(1) The thermal physical parameters of melt in casting zone are only determined by temperature. (2) The physical parameters of roller are constant. (3) The physical and inertial force are neglected. (4) There is no relative slide between solidification-shells and rollers, and they contact tightly. (5) The elastic deformation of the material is relatively small to the plastic deformation, thus it can be ignored. (6) The materials volume can not be compressed. (7) The materials are isotropic and homogeneous
