Abstract: The invention relates to a method for controlling the temperature of a melt (10), preferably of a steel melt, in a distributing vessel (11), whereby the temperature of the melt is measured, the measured result is compared with a predetermined temperature range in the form of specified values, and as much heat is supplied or withdrawn from the melt such that the temperature remains inside said range. In order to control the melt temperature, a fireproof shaped part (20) which is closed on both sides and which is provided for accommodating a liquid-cooled induction coil (1) is immersed in the melt (10). The transmission of heat is carried out by means of thermal conduction out of the wall of the shaped part (20) which is coupled to the induced electromagnetic field and/or by means of a direct coupling to the liquid melt (10). The shaped part (20) accommodates the induction coil (1) in an interchangeable manner while leaving cooling channels (9) open and is positioned from the outside by a manipulator (16) which can be lifted, lowered and turned.

Abstract: A process to hold molten aluminum alloy in a refractory lined vessel using heating elements disposed within ceramic immersion heating tubes to provide accurate temperature metal for the casting industry. The vessel is lined with multi thicknesses of high insulating refractory materials to minimize heat loss with contoured corners to allow smooth flow of circulating metal provided by a gear drive with rotary shaft and impeller. The heating elements are housed in a ceramic protection tube to prevent aluminum leakage which would result in element failure. The receiving and outlet wells are separated by refractory arches. An insulated inert gas purged cover is used over the heat chamber to reduce heat loss and allow for an inert purge gas to minimize surface oxidation. A thermocouple for temperature control is positioned in the exit chamber. A ceramic drain plug is provided to remove metal for maintenance.
