Abstract
A multi-furnace control system selectively delivers preselected percentages of available power to furnaces of the system, preferably designated as either a melt furnace or a hold furnace. The power supply delivers power to both furnaces. A capacitor station in parallel connection to the power supply and the furnaces is tuned to form a tank circuit therewith. Switches control the selected power delivered to the furnaces respectively and control the delivery of a first portion of the power for holding molten product in the hold furnace as the master control. A remaining portion of the power is then delivered for melting product in the melt furnace. The capacitor station acts as a reactive tank for both furnaces.
