Abstract

Tundish for continous casting of steel, of the type comprising a permanent refractory, cast on a frame of sheet metal defining the outer wall of the tundish and on which a refractory wear has been laid. In the body of the permanent refractory, there is provided a gas duct which penetrates into the permanent refractory at the level of the upper edge of the tundish and extends to the bottom of the tundish into a gas distribution chamber, which is covered with a surface distributed gas permeable plate. Application to the continuous casting of steels for tundish between casting ladle and ingot molds.
