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 Fourier-Kirchhoffs equation of the temperature field of slab- crystallizer system respectively slab-ambient system with these different thermophysical parameters : thermal conductivity, specific heat capacity, density and enthalpy including their dependence on temperature. 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 obviously 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 mix Original numerical model was applied to the simulation of the transient temperature field of concast steel slab of two different chemical composition.
