FE numerical simulation of mould temperature field during the continuous casting of steel

In this paper, the three-dimensional transient model of the mould temperature is established and the temperature variation is analyzed when the thickness of the mould wall and the cooling rates are different. For the numerical computation, a corresponding finite element method (FEM) program is developed with FORTRAN language, and six-face and eight-node isoparameter elements are applied; the Newton method is used to solve the heat equations. The experimental data have been used to validate the model. It is shown that the appropriate mould wall thickness is 10 mm and the different parts of the mould should correspond with cooling water of different rates.
