MOLTEN METAL FLOATING APPARATUS FOR CONTINUOUSLY HOT DIP COATING METAL STRIP

摘要

PURPOSE: A molten metal floating apparatus for continuously hot dip coating metal strip is provided to stably float molten metal using electromagnetic field in process for continuously coating the metal strip by passing the metal strip through a molten metal contained pot. CONSTITUTION: The molten metal floating apparatus for continuously hot dip coating metal strip comprises a plating pot(10) in which molten metal(20) is contained, and which is vertically penetrated in such a shape that the upper part of the plating pot(10) is wide while the lower part of the plating pot(10) is narrow; an attached pot(70) attached to the plating pot(10) in a bucket shape along the outer circumferential surface of the plating pot(10) with being adjacent to the upper part of the plating pot(10); a chamber(60) formed inside parts projected along the outer circumferential surface of the plating pot(10) with being adjacent to the lower part of the plating pot(10); an outlet(62) which is extended from one side of the chamber(60) in such a way that the front end part of the outlet(62) is gradually narrowed as it is being inclined upward, and which is formed by being directed to the center of the plating pot(10); a subsidiary pipe(72) for vertically connecting the attached pot(70) and chamber(60); an electromagnetic core(30) installed on the outer part of the plating pot(10) between the chamber(60) and attached pot(70); and an electromagnetic coil(90) which is coiled around the electromagnetic core(30), and to which an alternating current (A.C.) is conducted.
