ABSTRACT:
A continuous-casting apparatus in which the cover over the mold has an opening whose boundaries or inner edges are rounded and whose corners are rounded. The walls bounding the opening in the cover overlie and mate, as precisely as practicable, with the walls bounding the opening in the mold through which the molten metal flows. In addition, the surfaces of the walls which bound the opening of the cover and the adjacent surfaces of the cover have a fine finish and are coated with friction reducing and molten-metal adhesion-reducing material. The mating of the portions of the walls, the rounded inner edges and corners and the coating suppresses adhesion of spattered molten metal to the walls of the cover. The rounding of the corners formed by the walls which bound the opening in the cover provides a generally triangular channel, between the walls which bound the opening in the cover and the corners formed by the walls bounding the opening in the mold, through which lubricant flows to the walls bounding the mold.
