Abstract (en)

[origin: US2016121394A1] A furnace system for melting and casting metals, alloys, and superalloys and a related method. A melt chamber of the furnace system is configured and arranged to include at least two melt boxes, thereby increasing the volume of alloy charge that can be rendered molten during a single furnace heating cycle. Accordingly, a number of ceramic casting molds equal to the number of melt boxes can be used to form castings following a single furnace heating cycle. The ceramic casting molds can be pre-heated in an external oven before being introduced to the mold or loading chamber of the furnace system. The throughput of the furnace system is increased by the ability to pour more than one casting per alloy charge melting cycle.
