Abstract

PURPOSE:To uniformize the amount of plated metal adhered on the strip on both of front and back sides, by installing an auxiliary roller, to be driven inversely to the onward direction of the strip, nearby the upper surface of the molten metal bath, in case of executing the hot dipping process on the strip. CONSTITUTION:The strip 1 is introduced into the hot dipping bath 2 by the sink roller 3 and both of front and back sides are plated. Hereupon, the auxiliary roller 6 is arranged above the sink roller 3 so as to rotate inversely to the onward direction of the strip 1. This auxiliary roller 6 is located so as to locate its upper surface at almost equal level to the plating bath surface, or on the level 50mm lower than the bath surface. The gap between the side plane of the roller 6 and the ascending strip is sepecified to be 10-100mm. The amount of the plating metal for the strip 1, being pulled up by the surface of the strip from the side plane of the roller, is reduced owing to the inverse rotation of the roller 6. By adjusting the r.p.m. of the auxiliary roller 6, the thickness of plated metal adhered on both sides of the strip 1 can be uniformized.
