Název v původním jazyce

A breakout of a slab as effect of the change of chemical composition of a concast steel

Popis výsledku v původním jazyce

An important area of the caster is the so-called secondary cooling zone, which is subdivided into thirteen sections. In the secondary-cooling zone, where the slab is beginning to straighten out the breakout of the steel can occur in points of increased local chemical and temperature heterogeneity of the steel, from increased tension as a result of the bending of the slab and also from a high local concentration of non-metal, slag inclusions. Especially dangerous are the changes in the chemical composition of the steel during the actual concasting. In the case of two melts one immediately after the other, i.e. when melt of steel of quality A finished and right now the melt of quality B followed, this could lead to interruption in the concasting and a breakout. The material, physical, chemical and technological parameters, which both melts differed in were determined. The parameters from the temperature field were calculated by means of the model, for example maximal and minimal lenghts
