In the factory, the continuous thin steel plates are subjected to iron and steel processes are supported by a series of rollers during processes such as plating and rolling. However, because the rollers come in contact with the steel plates, the problem of surface quality deterioration arises. To solve this problem, we developed a non-contact guide system for parts of the steel plate at which its traveling direction changes in high-speed traveling by applying an electromagnetic force from the direction of the edge of the thin steel plate, and experimentally examined the effectiveness of the system. However, the asymmetry traveling steel plate during uncontrolled is not calculated theoretically. In this study, the shape of traveling steel plate is calculated with numerical analysis. It is confirmed that, as we compared analysis result with experiment result, both have similar tendency.
