A numerical optimization of concast steel slab and influence of the material thermophysical proprerties

Popis výsledku v původním jazyce

The thermophysical properties of steels have a significant influence on the actual concasting process and on the accuracy of its numerical simulation and optimization. The determination of these properties (heat conductivity, specific heat capacity and density in the solid and liquid states) often requires more time than the actual numerical calculation of the temperature fields of a continuously cast steel billet, cylinder or slab. The influence of individual properties should be neither under- nor oveer-estimated. Therefore, an analysis/parametric study of these thermophysical properties was conducted. The order of importance within the actual process and the accuracy of simulation and optimization were also determined. Individual properties, which,in some cases, were obtained from tables and in others experimentally, were substituted by an approximation using orthogonal polynomials. The accuracy of each polynomial is dependent on the precision of individual values. The order of sig
