ABSTRACT:
The invention is directed to a nozzle for feeding liquid metal to a moving mold of a continuous sheet casting machine, such as continuous casting between cylindrical rolls rotating about a horizontal axis. The nozzle is characterized by cheeks the inner side walls of which extend beyond the orifice initially by a straight element which can be composed of several parts then by a portion that is tapered to diverge from the nozzle axis at an angle of 5.degree. to 15.degree.. These cheeks may be strengthened in order to resist the strains caused by the solidified metal, and they may be provided with cooling or heating means. They are mounted to extend either into the area between the cylindrical rolls or to terminate outside their rolling area. The nozzle, which may be used in all kinds of continuous casting between cylindrical rolls has particular utility with continuous casting machines of high capacity for obtaining sheets or plates free of edge defects with light metals, such as aluminum and its alloys, or heavy metals, such as tin, lead, zinc, copper, and their alloys.
