Název v původním jazyce
Comparison of the temperature field continuously cast steel slabs with different chemical composition.
Popis výsledku v původním jazyce
Numerical model made by authors was applied to the simulation of the transient temperature field of continuously cast steel slab of two different chemical composition. The model solves the Fourier-Kirchhoff 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 breakout 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. Calculation of the temperature field of a slab has focused mainly on the part of the slab before the breakout and its surroundings. The results of the temperature field can establish a model of the chemical heterogeneity of steel supported by material expertise on samples taken from the breakout.
