Abstract
A slag control shape is releasably mounted on a mounting member carried on a cover of a molten metal vessel. A movable member is carried on the cover and moved by an actuator into engagement with and moving the mounting member to move the mounting member to a position releasing the slag control shape for insertion into the molten metal vessel. The actuator is a fluid operated cylinder having an extensible piston rod which is engageable with the movable member to move the movable member into engagement with the mounting member. A valve actuated remotely from the cover supplies pressurized fluid to the cylinder to extend the piston rod. Alignment sensors are mounted on the cover and an actuator support to ensure that the cover is rotatably positioned on the molten metal vessel to align the actuator and movable members.
