Abstract

To avoid loss of temperature of a melt contained in casting ladles in a continuous casting operation, an independently rotatable platform adapted to receive a heating device is disposed on a slewing column of a slewing tower for ladles. The heating device is similar to that of an arc melting furnace and comprises a vertically adjustable electrode holder of outrigger configuration whose guide column is arranged eccentrically on the platform so that a current carrying cable can be installed to extend centrally through the platform and through the slewing column. The cables are secured by a clamping plate at a perpendicular distance from the platform, such that the electrode holder, as seen from the casting position, can pivot in both pivoting directions through approximately 180.degree., without the cable tearing as a result of twisting.
