ABSTRACT:
The surface of a metal is treated in 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 is 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 coated layer of a metal or alloy having a low melting point on the surface thereof. In addition, during the surface treatment in the fluidized bed system, a heat treatment such as patenting or cooling may be applied concomitantly in combination therewith.
