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 actuatorA 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.

Strip casting apparatus

An arbourless casting roll for casting steel strip includes a cylindrical tube (,) of copper of copper alloy having a wall thickness in the range of 30 mm-200 mm and a series of holes defining longitudinal water flow passages (,). A pair of steel stub shafts (,) disposed one at each end of tube (,) have end formations (,) which fit snugly into the ends of tube (,) and have circumferential flanges (,) abutting the ends of the tube. Fasteners (,) extend through flanges (,) into at least some of the holes (,) to fix the stub shafts to the tube (,) such that the tube is unsupported between the stub shafts (,). Water flow ducts (,( in the stub shaft end formations (,) allow flow of water to and from the flow passages (,).

Casting steel strip

Twin roll strip casting apparatus in which a pair of pool confining side plates (,) engage end surfaces of casting rolls (,) to form side confining closures for the pool. Plates (,) are mounted in side plate holders (,) connected to horizontally acting thrusters (,) which apply inward closure forces to the side plates (,). Thrusters (,) are mounted on a pair of carriages (,) disposed one at each end of the casting roll assembly and movable toward and away from one another to enable the spacing between them to be adjusted so that the carriages (,) can be preset before a casting operation to suit the width of the casting rolls (,). Carriages (,) are mounted on a central frame structure (,) which sits over the casting rolls (,).

Twin roll caster for casting metal strip comprises pair of horizontal casting rolls (1) on which to support a casting pool of molten metal. A pair of side plates (18) engage end surfaces of rolls (1) to form side confining closures for the casting pool. A pair of side plate holders (25) hold plates (18) and thrusters (21) apply opposing inward closure forces to side plates (18). Thrusters (21) are connected to side plate holders (25) by pivot connections defined by horizontal pivot pins (26) and vertical pivot pins (28) which permit side plates (18) to self-align with the roll ends by rocking movements both longitudinally and laterally of the rolls but to constrain the plates against rotation in the general planes of the plates.
