Abstract

Process and apparatus for vertical continuous casting of metal in at lest one hot-top mold with metal supplied at constant level. The object of the invention is to provide a process and an apparatus that make it possible, while supplying metal at constant level, to avoid non-uniform temperature gradients, turbulence, and waste of metal. According to the invention this is achieved by coordinating the level, flow rate and distribution of molten metal to each hot-top mold from the outlet opening of a smelting furnace. This is produced by a pouring spout or trough that is supported through the upper wall area of each hot-top mold to supply molten metal to each hot-top mold through central outlet openings in the side walls of the trough, with the bottom of the trough being in a plane below the level of the outlet opening of the smelting furnace and below the upper surface of the melt in the hot-top mold, and with the trough outlet openings supplying molten metal to the center of each mold and causing it to flow outwardly therefrom.
