Abstract
Recently, along with high-end products, users demand steel plates with high quality and high added value manufactured by a continuous steel plate process. In the factory, the continuous thin steel plate subjected to iron and steel processes is supported by a series of rollers during processes such as rolling. In the plating process, the steel plate is conveyed 20-50 m in the vertical direction for drying, during which the steel plate is not supported by rollers and other mechanisms. Therefore, plating nonuniformity due to the generation of vibration and other factors prevents the increase in productivity. As one method of solving this problem, we have proposed a noncontact guide system which suppresses the vibration of a moving thin-steel plate by adding an electromagnetic force from the direction of the edge of the plate. In this study, we confirm the suppressive effect of the sliding mode control.
