Abstract

This thesis deals with ways to optimize the teeming of steel from the ladle. In the first part is devoted to characteristic of the continuous casting machine with a focus on the ladle and its parts and then describes the methods used to indication slag overflow from the ladle to the tundish. At the end of this chapter is the characteristic of the mechanism of entrainment of slag from a ladle. The second part is devoted to literary analysis focused on the current knowledge of the optimization of the outflow steel from the ladle. It contains the results from physical and numerical modelling used for study of the mechanism of slag entrainment. The influence of the shape of the ladle, inclination and the shape of the ladle bottom and location of the nozzle during the last stage of teeming steel from the ladle, which leads to slag entrainment to the tundish. In the final section summary of literary knowledge and conclusions was made.
