SINK ROLL BLADE APPARATUS USED IN CONTINUOUS MOLTEN METAL PLATING APPARATUS AND METHOD FOR PREVENTING OCCURRENCE OF DENTS

摘要

An apparatus installed in a molten metal plating line includes a blade press ed against a roll dipped in a molten metal plating bath, in which a metal strip travels. The apparatus removes substances deposited on a surface of the roll. The apparatus also includes an arm for supporting the blade, and a screw member disposed above the plating bath so as to traverse it and moving along an axis of the roll in th e bath for removing substances deposited on the roll in the molten metal plating bath. Floats and/or weights are mounted on the arm so as to adjust a press force of the blade applied to the roll in the molten metal plating bath. A method for preventin g the occurrence of dents on a molten-metal-plated steel strip using the apparatus is also disclosed.
