Title: Directly induced swing for closed loop control of electroslag remelting furnace

Abstract

An apparatus and method are disclosed for controlling an electroslag remelting furnace, imposing a periodic fluctuation on electrode drive speed and thereby generating a predictable voltage swing signal. The fluctuation is preferably done by imposition of a sine, square, or sawtooth wave on the drive dc offset signal. 8 figs.
