ABSTRACT
Twin-roll strip cast-rolling is a frontier process which produces a metallic strip directly from the melt. The main idea behind the presented research is to develop a new type of sectional roll surface heat transfer boundary condition. On this basis, a numerical simulation model of heat-flow coupling considering solidification was established to support the new boundary condition (BC). Finally, the simulation results are consistent with the experimental data, which verifies the BC. Meanwhile, the process parameters were optimized in depth through the model.
