摘要： 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.
