Original Abstract

The solidification and cooling of a continuously cast billet, slab or cylinder (generally a concasting) is a very complicated problem of 3-D transient heat and mass transfer. The solving of such a problem is impossible without numerical models of the temperature field. This paper is focused on the derivation of boundary conditions, i.e. the values of the heat transfer coefficient (HTC) on all CCM boundaries. The definition of boundary conditions is the most difficult part of the investigation of the thermokinetics of this process. The boundary conditions of the numerical model of the temperature field of the concasting are defined as the transfer of heat by convection. This HTC includes the so-called reduced convection coefficient corresponding to heat transfer by radiation. This paper therefore continues with a discussion on heat transfer coefficients under air-water cooling jets, which spray the concasting in the so-called secondary-cooling zone.
