Abstract: A refractory plug for blocking the tap hole of a steel making vessel or transfer ladle containing molten steel covered by a layer of slag and for minimizing turbulence caused by vortexing. The plug comprises a body having an inverted cone-shaped bottom and having an integral top portion projecting axially from a top base surface of the cone-shaped bottom portion. The plug is added to the melt just prior to or during the tapping operation to minimize vortexing and to plug the tap hole prior to egress of the slag.

Abstract: The unplugging apparatus includes an annular member having a refractory ring on its inner surface. A housing is supported by the member and connected to a radially disposed conduit. A tube in the housing is guided for upward movement by the housing. A nozzle may be provided on the upper end of the tube. The tube has a reaction surface within the housing and is adapted to be projected upwardly by gas introduced into the housing from the conduit. The tube has a passage so that the gas from the housing may be discharged through the nozzle.

Abstract: The bottom plug for ingot molds is frusto conical and at least the upper portion thereof, facing the metal, is formed of an unburned mixture of at least about 92 percent of fine grained refractory material and not more than 8 percent of an organic binder. The plug may have a lower less heat resistant layer and may also have a thin top covering layer or coating of a highly heat resistant metal oxide or of sheet metal and may have an upper surface shape e.g. disked to prevent splashing of the molten metal as it is poured into the mold.

Abstract: A device for regulating the flow through a plug of a dispensing vessel in a continuous casting installation, using the level of the metal bath in the receiving ingot mold, by means of a known electronic optical device. On each distributor there is a mechanical-reduction mechanism, with a purely mechanical proximity-control unit which is close to the casting unit and can be connected by a rapid coupling means to the mechanism. This control unit is actuated by a mechanical remote control from a remote-control console, which comprises both manual control and control by means of a servo-jack acting on the same mechanical transmission, while an emergency control is provided for acting directly on the proximity-control unit.

Abstract: A rotary slide closure for a vessel provided with a fire-proof lining includes a closure block contacting a beveled seat of a seat block and being rotatably mounted relative to the seat block. The closure block and the seat block each have at least one flow-through opening which can be brought into register by turning of the closure block so as to form a pouring channel extending from the center of the closure block. The surface of the seat block forming the beveled seat, faces the interior of the vessel and the closure block contacts the surface forming the bevel seat from the interior of the vessel.

Abstract: Teeming of molten metal from a laden vessel into a receiving vessel such as an ingot mould or tundish is accomplished at a controlled rate by detecting the changing weight of one of the vessels and deriving a valve control signal by comparing a changing weight signal with a presettable reference signal, the valve control signal being employed to adjust the setting of a sliding gate valve through which molten metal passes as it is teemed into the receiving vessel.
