ABSTRACT:
An apparatus for casting metal strip in which molten metal is applied to a casting roll the surface of which is cleaned by a cleaning brush device comprising a main brush extending across the roll surface by sweeper brush actuator28A and a sweeper brush extending across the roll and capable of tangentially engaging the peripheral longitudinal roll surface in advance of the main brushing device. Both brushes are mounted on mounting frames moveable to bring the main and sweeper brushes into contact with the casting roll. The sweeper brush is independently moveable on the frame by operation of an sweeper brush actuator to move the sweeper brush into engagement with the surface of the casting roll near the start and end of the casting run and the main brush actuator to move the main brush into engagement with the peripheral longitudinal surface of the casting roll during normal casting operation.
