Abstract
A mobile holding furnace having a metering pump is adapted to hold a relatively small quantity of molten metal in a contamination-free condition for dispensing to individual molds. The furnace is provided with insulation and electric heating elements for maintaining the molten metal in a liquid state. The furnace is sealed such that an atmosphere of inert gas can be maintained above the level of molten metal. The furnace is mounted upon wheels for easy transportation from place to place. The furnace is used in conjunction with tracks disposed adjacent individual molds, the tracks permitting the furnace to be locked in place while molten metal is dispensed into the molds.
