FINITE-ELEMENT 3-DIMENSIONAL MODELING OF THE SOLIDIFICATION OF A METAL-FORMING CHARGE

The paper deals with the modelling of density changes during the solid ification of the ingots and cast strands after casting. The finite ele ment solution of the Navier-Stokes equations are implemented into the modelling of the process. The models for both steady-state and non ste ady-state solutions as well as the influence of the physical parameter s distribution in the cooling zone on the solidification process are d iscussed. Some results of the density distribution in the cross sectio ns of a hot-top ingot during solidification process after casting are presented. Some aspects of the numerical solution are discussed.
