Abstract:The corner temperature has a great influence on the quality of the slab, three-dimensional steady-state mathematical model of the temperature field of a rectangular mould, a 2-hole plus 1-slot chamfered mould, a 3-hole chamfered mould and a 3-hole plus 1-slot chamfered mould were established. Under the same boundary conditions, the cooling behavior and heat transfer characteristics of these four moulds were analyzed. The numerical simulation results of temperature distribution of different types of copper plates show that compared with the rectangular mould, the corner temperature of the chamfering mould copper plate is obviously improved, and the lateral temperature distribution of the narrow face is different from the rectangular mould, showing a "W" shape distribution. The results showed that the 2-hole plus 1-slot chamfered mould narrow-faced copper plate has better heat transfer performance than other types of narrow-faced copper plates, and the temperature distribution is uniform, which provides a theoretical basis for the design of the copper plate.
