The invention relates to a simulation method used for predicting the heat condition parameter of a high-temperature waste gas circulation sintering process. The simulation method adopts the following technical scheme that a microscopic single-particle micro-unit mechanism model is established, a macroscopic material layer mathematic model of the high-temperature waste gas circulation sintering process is established on the basis of the microscopic single-particle micro-unit mechanism model, heat effects, including water migration, limestone decomposition, coke powder burning and the like, which obviously affect a sintering process are solved through the microscopic mechanism model, a calculation result is weighted as the mass resource item and the heat source item of the macroscopic model so as to more approach to a practical sintering process on an aspect of the mechanism, and therefore, simulation precision is improved. The simulation method is used for solving the problems of low accuracy, long simulation time and low efficiency of a traditional simulation way.
