Body-fitted coordinate transformation equation was deduced and used to generate the body-fitted grids of molten pool for twin-roll strip casting. The orthogonality of the grids on the boundary was modified by adjusting source item. The energy equation and the boundary conditions were transformed from physical space to computational space. The velocity field model proposed by Hirohiko Takuda was used to calculate the temperature field of molten steel, and the influence of technical factors was also discussed.
