ABSTRACT:
An improved tundish is disclosed, for use in combination with a casting ladle and a casting mold to continuously cast metal slabs. This tundish comprises an elongated, flat-bottomed basin known as a flotation box in between a pouring box with a vertical partition and an antivortex box. A first recess is provided in the bottom of the basin just under the partition to prevent any slag formed upstream of the partition from being entrained. The first recess also creates an upward stream rising from the bottom of the recess along the partition downstream the same, which allows optimal inclusion separation and substantial reduction of the dead volume zones in the basin downstream the partition. A second recess from which an outlet nozzle downwardly extends, is also provided in the bottom of the basin adjacent to the end of the flotation box. This second recess forms an antivortex volume above the outlet nozzle, thereby allowing substantial reduction of the metal left in the tundish on every casting sequence. This new configuration leads to better inclusion separation, less skulling and higher metallic yield.
