Abstract Heat transfer process of continuous casting grids mold determines the acceptable quality of continuous casting grids. The heat transfer in continuous casting grids mold on the basis of the first law of thermodynamics and the Fourier law (the law of heat conduction) was analyzed and studied. According to simplified model of continuous casting grids mold established the steady-state compound heat transfer model of the cooling oil end cover air,the high temperature lead liquid and the outer cylinder of the moving mold and the cooling oil and the heat release calculation model of the cooling oil.Then the heat transfer dynamic balance equation of continuous casting mold was established. In order to guide the production practice, the operation function of operation process is established. Through the theoretical analysis of the heat transfer process of the grid continuous casting mold, this study has certain guiding significance for improving the continuous and stable production of the grid continuous casting mold and realizing the automatic temperature control of the grid continuous casting mold.

Key words： grids continuous-casting-mold first law of thermodynamics heat conduction law dynamic balance equation
