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
