Abstract

A numerical model of heat transfer in a system "plate casting-mold-surroundings" F. Kavicka & J. Stetina Faculty of Mechanical Engineering, Brno University of Technology, 61669 Brno, Czech Republic Abstract The solidification and cooling of a casting, and the simultaneous heating of the mold, is a very complicated problem of transient heat and mass transfer. The solving of such a problem is impossible without numerical models of the temperature field, not only of the actual casting, but the mold as well. This process is described by the Fourier equation. An original three-dimensional (3D) numerical model of the temperature field of a system, comprising a plate casting, the mold and the surroundings, had been assembled and used to optimize the production technology of a vertically cast steel plate. The accuracy of a numerical model depends not only on the spatial and temporal discretization, but also on the accuracy with which the thermophysical properties
