Abstract Horizontal continuous casting is an important step in the casting and rolling process of copper strip. Its core physical process includes flow, heat transfer and solidification. The experimental research is inconvenient and limited, so numerical simulation is often used to analyze the quality and structure of the casting billet. In order to further improve the accuracy and completeness of the simulation, a coupling numerical model of flow-heat transfer process and heat-solidification process of copper slab horizontal continuous casting was established, and a high-precision field transfer algorithm between different grids was designed. By controlling the input parameters and boundary conditions, the consistency of the temperature field between the flow-heat transfer model and the heat transfer-solidification model is achieved, which solves the problem that the traditional model cannot couple the flow field to calculate the solidification microstructure, and the accuracy of the coupled simulation results is confirmed through the production test.
