摘要： Provided are a molten metal plating facility and a method with which degradation in the surface quality of a strip can be prevented by preventing the adhesion of splashes. In a molten metal plating facility and a method for plating a strip (S) with molten metal by guiding the strip (S) into a molten metal bath (Mm) and then guiding the strip (S) upward, a pair of wiping nozzles (12a, 12b) disposed so as to face a front surface side and a back surface side of the strip (S) guided upward is used to discharge air streams (Ea, Eb) toward a collision point (A) inside the strip (S) such that the first air streams spread out in a strip width direction of the strip (S), and a pair of outer nozzles (15a, 15b) disposed so as to face a front surface side and a back surface side of an extended plane on an outer side of the strip (S) with respect to the strip width direction, above the wiping nozzles (12a, 12b) and on each of both outer sides of the strip (S) with respect to the strip width direction is used to discharge air streams (Fa, Fb) toward a collision point (B) within the extended plane and below the collision point (A).

摘要： The invention relates to an apparatus and a process for the hot-dip coating of a metal strip (M) with a metallic coating, in which the metal strip (M) is passed continuously through a molten bath (3), in which the thickness of the metallic coating that is present on the metal strip (M) when it leaves the molten bath (3) is set by means of a stripping device (7), and in which slag (S) that is present on the molten bath (3) is driven away from the metal strip (M) leaving the molten bath (3) by means of a stream of gas (G1, G2). In order to prevent slag from coming into contact with the metal strip leaving the molten bath by simple and inexpensive means in the case of such a process, and thus ensure optimum quality of the surface, to drive the slag (S) away from the metal strip (M), the invention proposes directing a stream of gas (G1, G2) that extends over the width (B) of the metal strip (M) onto the surface (6) of the molten bath (3) by means of at least one nozzle (10, 11) arranged closely alongside the metal strip (M).
