| Abstract: | A mathematical model depicting the flow and he at transfer in the inverse solidification mold is built up according to the continu um model.Results of studies reveal the law of three phase changes about th e solidified strand in the mold: fast growing phase, balance and stalemate phase and fast remelting phase.In comparison of the experimental data of the strand t hickness.with the simulation data it is proved that the model is correct and fu nctions well. |
