Abstract:Based on the characteristics of mold heat transfer,a three-dimensional transient heat transfer model of billet continuous casting mold is established. Casting process of the billet is simulated by a node temperature transfer method. The ANSYS finite element software is used to analyze the model. The three-dimensional steady-state temperature field of the billet mold is obtained by sufficient iteration and compared with the traditional two-dimensional model. The influence of scale on mold temperature distribution has been analyzed through the continuous change of the scale loading technique of dynamic boundary conditions. The result is detailed as follows. The analyzed result obtained by three-dimensional heat transfer model in the top zone of the mold is basically coincident with copper wall temperature distribution rule. The copper wall temperature reached its peak at 50 mm near the meniscus. The highest temperature of copper wall would be increased from 187 to 318 ℃ when meniscus scale thickness added from 0.1 to 0.5 mm. In this case,high temperature region of copper wall would be expanded so that copper wall deformation degree could be increased.
