Abstract
In this study, the dispersion behavior of a ferroalloy containing cerium in a steel melt and the concentration along the slab length were predicted by a fluid analysis and spreadsheet-based model development in the continuous casting process. The residence time distribution of the ferroalloy according to the flow pattern was calculated and used for calculating the ferroalloy discharge rate from the tundish and concentration in the slab. Effective operating conditions for homogeneous concentration distribution of the ferroalloy were determined by controlling the injection speed and time of the ferroalloy obtained from this analysis model.
Key Words
