Original abstract

The chemical composition of steels has significant influence on the actual concasting process, and on the accuracy of its numerical simulation and optimization. The chemical composition of steel affects the thermophysical 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 slab. Therefore, an analysis study of these thermophysical properties was conducted. The order of importance within the actual process and the accuracy of simulation were also determined. The order of significance of the chemical composition on thermophysical properties was determined with respect to the metallurgical length. The analysis was performed by means of a so-called calculation experiment, i.e. by means of the original numerical continuously cast model developed by the authors of this paper. It is convenient to conduct such an analysis in order to facilitate the simulation of each individual case of continuously cast, thus enhancing the process of optimization.

Czech abstract

Chemické složení ocelí má významný vliv na skutečnou concasting procesu a na přesnost jeho numerické simulace a optimalizace. Chemické složení oceli, ovlivňuje termofyzikálních vlastností (tepelné vodivosti, měrné tepelné kapacity a hustoty pevných a kapalných státy) často vyžaduje více času, než je aktuální číselné výpočet teplotních polí s plynule lité oceli desky. Proto byla provedena analýza studie těchto termofyzikálních vlastností. Pořadí důležitosti v rámci samotného procesu a přesnost simulace byly určeny také. Pořadí významu chemického složení na termofyzikálních vlastností byla stanovena s ohledem na délku hutní. Analýza byla provedena pomocí tzv. výpočet experiment, to znamená originální numerické plynule litých model vyvinutý autoři tohoto dokumentu. Je vhodné provést takovou analýzu, aby se usnadnilo simulaci každého jednotlivého případu neustále obsazení, čímž se zlepší proces optimalizace
