Abstract
Recently, along with high-end products, users demand high quality and high added value of steel plates manufactured by the continuous steel plate process. In the factory, the continuous thin steel plate subjected to iron and steel processes is supported on a series of rollers during processes such as rolling; the thin steel plate moves on the rollers at a speed of 10m/s or more. In the plating process, the steel plate is conveyed 20-50m in the vertical direction for drying, during which the steel plates are negligibly supported by rollers and other mechanisms. Therefore, plating nonuniformity due to the generation of vibration and other factors prevents the increase of productivity. To solve this problem, we developed a new noncontact guide system for parts of the steel plate at which its traveling direction changes by applying an electromagnetic force from the direction of the edge of the thin steel plate, and experimentally examined the effectiveness of the system.
