摘要： A slag control shape (32) is releasably mounted on a cover (28) for a molten metal vessel (10). An actuator (60) is connected to a slag control shape release member to retract the release member from a first position engaged with the slag control shape to a second position separated from the slag control shape allowing 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. In one embodiment, the actuator is a flexible cable (60) attached at one end to the release member mounted on the cover and having a second end (66) located remote from the cover at an easily accessible operator position. In another embodiment, one end of a cable wound in a plurality of turns about a rotatable shaft mounted in a reel (212) is attached to the slag control shape. A spring (230) biasingly engages the shaft to control the rate of rotation of the shaft and thereby the rate of payout of the cable and the rate of descent of the slag control shape into the molten metal vessel. A detector (242) counts the revolutions of the shaft as the cable is paid out to measure the distance the slag control shape has descended into the vessel.

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).

摘要： An anti-slag, anti-vortex tundish measurement apparatus (10) for use in tundishes (14) or other molten metal receptacles provides a measurement of the depth of the molten metal layer (12) above the bottom (16) of such receptacles. A body (30) is mounted on a first end of an elongated rod (32). The body (30) and the rod (32) are formed of a suitable material and have a predetermined size such that the specific gravity of the body (30) and the rod (32) enables the body (30) to be buoyantly supported at the interface between the slag layer (24) and the molten metal layer (12). Measurement indicia (40) is formed on the second end (36) of the rod (32), which second end (36) slidably extends through a cover (50) externally from the interior of the receptacle (14).

摘要： L'invention se rapporte à un appareil de mesure anti-scorie et anti-tourbillon (10), qui est conçu pour être utilisé dans des avant-creusets (14) ou dans d'autres récipients pour métaux en fusion et qui sert à mesurer la profondeur de la couche de métal en fusion (12) au-dessus du fond (16) du récipient. Un corps (30) est monté sur une première extrémité d'une tige allongée (32). Le corps (30) et la tige (32) sont composés d'un matériau approprié et présentent une grandeur prédéterminée, de sorte que le poids spécifique du corps (30) et de la tige (32) permettent au corps (30) de se maintenir grâce à son pouvoir flottant à l'interface entre la couche de laitier (24) et la couche de métal en fusion (12). La tige (32) comporte des repères de mesure (40) sur sa seconde extrémité (36), laquelle coulisse à travers un couvercle (50) de façon à se déplacer vers l'extérieur à partir de l'intérieur du récipient (14).
