ABSTRACT:
A tubular mold element is concentrically surrounded by a jacket defining an annular space therewith and a casing defining a chamber with the jacket. A liquid-tight element divides the chamber into a lower inlet chamber for a cooling liquid and an upper outlet chamber for the liquid. The annular space communicates at the respective ends of the jacket with the inlet and outlet chambers so that a cooling liquid film circulates through the space. The liquid-tight element comprises a first annular member affixed to the interior wall of the casing and a second annular member affixed to the exterior wall of the jacket so that the liquid-tight element supports the jacket at its lower end while its upper end is free of support. The upper end of the tubular mold element is supported in a central orifice of the mold cover which delimits the upper outlet chamber and the lower end of the mold element is centered liquid-tightly in a central orifice of the bottom mold wall delimiting the lower inlet chamber, the mold element being resiliently coupled to the bottom wall. An electromegnetic inductor is arranged in the outlet chamber for moving the molten metal in the passage of the mold element and the inductor is supported on the exterior wall of the tubular jacket.
