Abstract
The present invention relates to method and apparatus for heating a strip of metallic material in a continuous annealing furnace and more particularly to an improvement relating to a method and apparatus for heating a strip of metallic material in a continuous annealing furnace in which annealing of the strip is continuously carried out in such a manner that a gas serving to adjust temperature of the strip, is blown toward the strip through a plurality of gas jet nozzles which are arranged on one side or both sides of the strip, wherein the temperature and flow rate of the strip are properly determined to a required level in response to the changing of the operating conditions such as the heat cycle, line speed, thickness of strip, width of strip and the like. Further, the present invention relates to a method and apparatus for heating a strip of metallic material in a continuous annealing furnace, wherein the temperature of the strip is controlled to reach a target temperature by heating or cooling the strip by means of a gas jet or the like having excellent respondency at a part of the heating zone in the continuous annealing furnace whereby irregular annealing of the strip is effectively inhibited.
