Abstract

in this paper, the author used method of Two-dimensional finite difference to establish a model of temperature in hot rolled steels in finishing stands, and used explicit difference method to solve the difference model. The model was optimized by correct parameters through particle swarm optimization combining with measure data. It has been verified that the deviation of the models prediction and real data keeps between ±10°C.
