ABSTRACT:
A method for controlling operation of a galvanneal induction furnace includes the steps of providing a steel strip having a molten zinc coating applied thereto and transporting the strip to an induction furnace in which the strip and coating are to be alloyed. The temperature which the strip is estimated to attain just prior to entering the furnace is then calculated. A temperature which the strip should achieve during the alloying reaction is then selected. The power which must be applied to the furnace to elevate the strip temperature from the estimated temperature to the alloying temperature is then calculated. Power is then supplied to the furnace.
