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 hottop 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 hottop mold, and with the trough outlet openings supplying molten metal to the center of each mold and causing it to flow outwardly therefrom.
