Abstract

PURPOSE:To make possible dross-gripping and uniform wiping of face and back surfaces simultaneously, by combining two rolls of different roll diameters. CONSTITUTION:Wiping rolls 4a, 4b of different diameters are so aranged that the line connecting their centers is not horizontal, hence the strip passes between the rolls, and the rolls have preliminary wiping performance that wipes face and back surfaces equally because they are installed near the upper surface of the bath. Wiping nozzles 3 are used for spraying high press. nonoxidizing gas through the nozzle slits in order to control the plating thickness. The nozzles 3 can move on toward the strip because the wiping rolls 4a, 4b correct the C-shaped warp and restrain the shake of the strip 1.
