In a factory, a continuous thin steel plate subjected to iron and steel processes supported by rollers tends to experience plate vibrations that lower the quality of the surface finish. In the plating process, rollers negligibly support the steel plates. Therefore, plating nonuniformity due to the generation of vibrations and other factors prevents an increase in productivity. To solve this problem, we developed a noncontact guide system in which electromagnetic and permanent magnet forces are applied at the edges of the steel plates. However, the negative effect caused by the negative spring force of the permanent magnet has, to date, not been examined. In this study, the optimal relationship between the magnetic flux density of a permanent magnet and the gap between the steel plate and the surface of the permanent magnet was examined.
