Abstract:
1. A tundish for producing and transferring high-purity metal melt from a casting ladle into a permanent mold of a continuous-casting installation, the tundish having a refractory lining which defines a refractory-lined interior space of the tundish, the lining having a refractory-lined surface area which, as a function of an operating bath level (h), satisfies the condition that a dimensionless ratio (κ) of the refractory-lined surface area (A ref ) which is wetted by the metal melt to the filling volume (V) which is delimited by the refractory-lined surface area (A ref ) and the bath-level-dependent exposed surface area (A Top ) and results from a relationship be between 3.83 and 4.39.
