ABSTRACT:
Disclosed is a method for measuring the extent of slag deposit buildup in the channel of a channel induction furnace during operation. The method comprises measuring an initial temperature rise factor in the furnace at a time when no slag deposits are present, measuring a subsequent temperature rise factor in the furnace after the furnace has been in operation for a period of time, correcting the subsequent temperature rise factor for any changes in the operating temperature and power levels applied to the furnace which may have taken place between the time of the measurement of the initial temperature rise factor and the time of the measurement of the subsequent temperature rise factor, and determining a quantity which is indicative of the extent of slag deposit buildup in the channel from the difference between the initial and subsequent temperature rise factors. The temperature rise factor in the furnace is defined as the ratio of the total weight of the molten metal in the furnace to the time required for the temperature of the molten metal to rise by a predetermined amount above the operating temperature of the furnace when the induction heating power applied to the furnace is increased by a specified amount above the operating power level of the furnace.
