<p>A surface treatment for a metal according to a fluidized bed system, in which a hot rolled metal is continuously subjected to an in-line treatment to suppress the formation of scale on its surface or to remove the same therefrom, and then introduced into a gaseous fluidized bed of a non-oxidizing gas, which contains metal or alloy particles having a low melting point, as fluidized particles, so as to bring the hot rolled metal into contact with the fluidized particles. As a result, the fluidized metal particles or alloy particles may be melted and solidified on the surface of the rolled metal to provide a coating layer of a metal or alloy having a low melting point on the surface thereof. In addition, during the surface treatment according to the fluidized bed system, heat treatment such as patenting or cooling may also be applied in combination therewith at the name time.</p> |
