Liquid cooled electromagnetic continuous casting mold

Claim 1

In a mold for the continuous casting of molten metal, which comprises a tubular mold element having two open ends and defining a passage for the casting between the open ends, a casing surrounding the tubular mold element and defining therewith an annular enclosed space, and an electromagnetic inductor means arranged in the annular enclosed space for moving the molten metal in the passage, the inductor means and the tubular mold element defining an annular gap therebetween, the improvement of 1. a tubular jacket mounted in the annular gap, the jacket defining a. an inner annular space with the tubular mold element, the inner annular space being laterally confined by the mold element and the jacket for cooling the mold element, and b. an outer annular space with the inductor means, the outer annular space being laterally confined by the jacket and the inductor means for cooling the inductor means; and 2. an annular liquid-tight element at one end of the annular enclosed space and arranged between the jacket and the casing to separate the enclosed space into an inlet chamber for a liquid cooling medium and an outlet chamber for the liquid cooling medium, a. the inductor means being mounted in the outlet chamber; and b. the inner annular cooling space being in communication with the inlet chamber at one end of the jacket and with the outlet chamber at the other end thereof.
