Abstract

A mold with a cooling jacket for the continuous vertical casting of metal billets, comprising between the lower part of the mold and the jacket a tubular wall the upper part of which is surrounded by ribs forming with the external side of the wall and with the internal side of the jacket a plurality of channels, said tubular wall forcing the cooling liquid introduced laterally into the jacket first to rise, then to divide itself regularly between the said ribs and to form simultaneously a laminar flow, then to flow down in that state along the mold and to leave in that state the cooling space through an annular slot.
