Analysis of Atypical Breakout During Radial Continuous Casting of Slab in the Straightening Zone I. Numerical Simulation of Temperature Field of a Slab

Popis výsledku v původním jazyce

Original numerical model was applied for simulation of the transient temperature field of continuously cast steel slab of two different chemical composition. The model solves the Fourier-Kirchhoff´s equation of the temperature field of slab-mould systemor slab-environment system with following various thermo-physical 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 the so called breakout occurs at a certain point of the secondary cooling zone of a caster. It is obviously caused by 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 the cross-section of the slab during its movement through the whole caster from the level of the melt in the mould to the cutting torch for both melts a
