ABSTRACT:
To achieve the highest possible separation rate for foreign particles in a tundish combined, at the same time, with a minimized level of inclusions, the refractory-lined interior space of the tundish, as a function of an operating bath level (h), satisfies the condition that a dimensionless ratio (κ) of the refractory-lined surface area (Aref) to the filling volume (V) which is delimited by this refractory-lined surface area and the bath-level-dependent exposed surface area (ATop) and results from the relationshipκ=Aref(V)23be between 3.83 and 4.39.
