METHOD, SYSTEM AND APPARATUS FOR SCRAPING A ROLL SURFACE IN A MOLTEN METAL COATING PROCESS

摘要

Apparatus for scraping the surface of a sink roll in a molten metal coating process comprises a support member having movable arms disposed on opposite sides of said support member. Each arm includes a scraper assembly portion. Scraper assemblies include a forward blade and a rear blade. A blade-connecting portion has a pivot point attaching the connecting portion to the arm. for following the radial contours of the roll surface. A second pivot point permits the blades to follow the crown of the roll. Pneumatic cylinders advance the arms such that at least one scraper blade presses against the roll surface under pressure. Also included is means for controlling the pressure of the scraping force applied to the roll surface. A traversing means provides for lateral movement of the blades along the axis of the roll.
