摘要： A slag control shape is releasably mounted on a cover for a molten metal vessel. An actuator is connected to a slag control shape release member to move the release member from a first position engaged with the slag control shape to a second position disengaged from the slag control shape to allow the slag control shape to descend into the molten metal vessel. Upon the occurrence of a predetermined condition, such as a predetermined weight of molten metal in the vessel or a predetermined total time of molten metal discharge from the vessel, a controller generates a signal to the actuator to automatically release the slag control shape into the vessel. The controller is located remote from the actuator and transmits the activation signal to the actuator by radio frequency signals, directly through an electrical conductor, or to a light emitter which transmits a light beam to a photodetector mounted on the cover.

摘要： 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.
摘要翻译：渣控制形状可释放地安装在承载在熔融金属容器的盖上的安装构件上。可动构件承载在盖上并由致动器移动以与安装构件接合并移动，以将安装构件移动到释放用于插入熔融金属容器的炉渣控制形状的位置。致动器是具有可伸展活塞杆的流体操作的气缸，可伸缩的活塞杆可与可移动构件接合，以使可移动构件与安装构件接合。从盖子远程启动的阀将加压流体提供给气缸以延伸活塞杆。对准传感器安装在盖子和致动器支撑件上，以确保盖子可旋转地定位在熔融金属容器上以对准致动器和可移动构件。
