This paper describes the new width control system that utilized the diaphragm phenomenon seen in the heat treatment process of a steel plate manufacturing process. This system derives the creep composition formula under the high temperature condition of a steel plate, designs each control system which constitutes a system and verified the possibility of this new width control system by computer simulation (1/10 scale). As a result of examining the capability of the equipment and investigating the change action of width by a numerical simulation, following result is obtained that width control is realizable on calculation. By this system, the improvement in manufacture efficiency and large cost reduction are expected since width change can carry out easily and sharply.
