Abstract Based on the structure and operation parameters of a T-type tundish, a 3-D mathematical model has been developed to study the flow field and heat transfer of molten steel in the T-type tundish by the software FLUENT. Aiming at the problems existing in the thermal boundary condition for the numerical simulation of molten steel in the tundish, a mathematic model of tundish liner to study the heat transfer in the T-type tundish liner was introduced. The relationship between the heat flux and the temperature of inside-wall in the liner is used as the thermal boundary condition to simulate the flow field and heat transfer of molten steel in the T-type tundish by the software FLUENT. Simulation results show that the thermal boundary condition according to the mathematic model of tundish liner can obtain a result of flow field and heat transfer of the molten steel in the T-type tundish more conform to the reality than using the commonly thermal boundary conditions.
