Abstract
The continuous casting of magnesium alloys in vertical upward direction is a novel technology which can be employed for the production of semi-finished materials circumventing the main disadvantages of using conventional casting processes since the risks of burning and explosion are practically eliminated. The present investigation deals with the simulation of the upward continuous casting of round billets of magnesium alloys. The equations for the flow field with heat transfer are numerically solved by a finite volume method and the solidification is accounted via an enthalpy-porosity formulation where the mushy region is modeled as a pseudo porous medium. The obtained temperature distribution is then used as input for a thermo mechanical analysis to determine the stress field in the billet during the casting process. Several configurations have been simulated and comparison of computed results with available experimental data is provided.
