Abstract: An apparatus and a method for coating zinc on steel sheets for use on automobiles and electronic apparatuses are disclosed. A fluidized bed forming chamber is provided to fluidize zinc powders in carrying out a zinc coating on a heated steel sheet, so that not only a uniformly coated layer but also a thick coated layer can be obtained. The apparatus for continuously coating zinc on a steel sheet according to the present invention includes a zinc coating chamber for forming a fluidized bed of zinc powders, for passing a heated steel sheet through the fluidized bed of the zinc powders, and for making the zinc powders melt-adhere on the steel sheet during its passing through the fluidized bed. A fluidized bed forming chamber forms a fluidized bed of the zinc powders by making the zinc powders suspended by spouting a gas.
