摘要： The present invention provides a new and improved method and apparatus for tapping molten metal through the top hole of a metallurgical vessel (2). The apparatus utilizes a ladle or a BOF furnace or other metallurgical vessel (2) used for the containment of molten metal. At least one extension drive mechanism (24) is attached to the support structure (6) position the distal end of a lance (32) within the vessel (2) a predetermined distance above the surface (16) of its contents. The lance (32) is connected to an inert gas source (26) such as Argon. Once the lance is properly positioned, the inert gas is directed onto the surface (16) of the molten metal to prevent the slag from entering the tap hole (4). An alignment drive (30) can also be attached to the support structure (6) to adjust the position of the extension drive (24) relative to the vessel (2) so that the lance (32) may be properly positioned within the vessel (2) above the tap hole (4). The extension (24) and alignment (30) drives are operatively controlled by a computerized controller (22) which interfaces with the sensors to monitor the physical characteristics of the vessel (2). The controller (22) operatively controls the drives to position the lance (32) a predetermined distance above the tap hole (4) of the vessel (2).

摘要： A slag control shape (32) is releasably mounted on a cover for a molten metal vessel (10). An actuator (164) is connected to a slag control shape release member (100) to move the release member (100) from a first position engaged with the slag control shape (32) to a second position disengaged from the slag control shape (32) to allow the slag control shape (32) to descend into the molten metal vessel (10). Upon the occurrence of a predetermined condition, such as a predetermined weight of molten metal in the vessel (10) or a predetermined total time of molten metal discharge from the vessel (10), a controller (152) generates a signal to the actuator (164) to automatically release the slag control shape (32) into the vessel (10). The controller (152) is located remote from the actuator (164) and transmits the activation signal (164) 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 (28).

摘要： A slag control shape (32) is releasably mounted on a cover (28) for a molten metal vessel (10). An actuator (60) retracts a release member from engagement with the slag control shape to allow the slag control shape to freely drop into the molten metal receptacle. The actuating end of the actuator is located at an easily accessible operator position for remote actuation of the release member. The release member (286) is mounted on a lid (260) removably mountable in a bore (42) in the cover (28) and the actuator (304) is mounted on the cover and releasibly connected to the release member (286). In another embodiment, the release member (366) is mounted on a base (352) which is in turn removably mounted in the bore (42) in the cover (28). The hanger (48) of a slag control shape (32) extends through an aperture in the base (352) and is engaged by the release member (366).
