Abstract: 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).

Abstract: A pickling facility includes: a pickling tank for storing an acid solution; a conveyance part for continuously conveying a steel plate immersed in the acid solution; a measurement part for measuring at least one parameter which has a correlation with a heat transfer coefficient between the acid solution and a reference surface disposed in the acid solution so as to face the steel plate; and a conveyance speed decision part configured to decide a conveyance speed of the steel plate conveyed by the conveyance part, on the basis of a measurement result of the at least one parameter.
