dcterms:description
Original numerical model was applied to the simulation of the transient temperature field of concast steel slab of two different chemical composition. The model solves the Fourieor-Kirchhoffs equation of the temperature field of slab- crystallizer system respectively slab-ambient system with these main thermophysical parameters : thermal conductivity, specific heat capacity, density and enthalpy. When both melts follow closely after each other, the critical state of so called break out occurs at a certain point secondary cooling zone of a caster. It is probably a combination of surface defects. However different chemical composition of two steels and their mixing is apparently decisive. Therefore the temperature model has simulated the temperature history of every point of a cross-section of a slab during its movement through the whole caster from the level of the melt in the crystallizer to the cutting torch for both melts and and for their mixture.
