Abstract
The invention relates to a method for manufacturing a hot-dip plated metal strip comprising the steps of: introducing a metal strip into a molten metal bath of plating metal to adhere the molten metal onto the surface of the metal strip; taking out the metal strip, after turning the running direction of the metal strip, from the molten metal bath without applying external force from outside the surface of the metal strip; adjusting the plating weight of the molten metal adhered onto the metal strip; and controlling the shape of the metal strip using magnetic force in non-contact state directly before or after the step of adjusting the coating weight. The invention prevents adhesion of dross to the metal strip without degrading the productivity, and thus manufactures a high quality hot-dip plated metal strip.
