Original Abstract

This paper brings new findings in the field of heat and mass transfer during solidification (crystallization) and cooling. Following the thermo physical phenomena and parameters are simulated: development of latent heat of phase or structural changes, prediction of the character of primary crystallization, speed of casting and its optimization, cooling of the mould, mould oscillation, intensity of cooling in the secondary zone by means of water or water-air nozzles, prediction of the position of the latest solidification. This original 3D numerical model is capable of simulating the temperature field of a caster. The presented model is a valuable computational tool and accurate simulator for investigating transient phenomena in caster operations, and for developing control methods, the choice of an optimum cooling strategy to meet all quality requirements, and an assessment of the heat-energy content required for direct rolling.
