摘要： For separating slag from heavy metal melts, as iron, steel and copper, a pipe-like body is used into which the slag and metal are drawn and which is rotated about its axis to cause the molten metal to form a layer within the pipe-like body on the outside of a slag layer, the dividing surface between the slag and the metal having the shape of a part of a paraboloid of revolution. The arrangement is tilted at an angle, and at its upper end is provided with a wall over which the slag can escape while holding the molten metal. At its lower end it is provided with a trap arrangement which allows molten metal to flow back downwardly into the main body of melt while preventing the return of the slag.The arrangement can also be used as a mixer.

摘要： Slag on the surface of a molten metal is drawn into the inlet end of a suction pipe which is provided with a water cooling jacket having orifices permitting the flow of water to the inlet end of the pipe for pelletizing the entering slag. The suction pipe is connected to a separator hopper, which is evacuated by an exhaust pump to create the suction, and which includes a slag discharge port closed by an openable valve. A sealed auxiliary hopper receives slag from the discharge port of the separator hopper when the valve thereof is opened, and also includes a slag discharge port closed by an openable valve. The hopper discharge valves are operated alternately by suitable control means so that when one valve is open the other is closed, thereby enabling slag to be continuously sucked, separated, and intermittently discharged from the auxiliary hopper.

摘要： Apparatus and process for deslagging molten metal such as steel. Molten steel is prepared in a conventional melting furnace and is tapped into a ladle. A vacuum is applied to the slag on the surface of the steel in the ladle by means of an uptake tube containing a thermally insulating paper or refractory lining. The proximity of the uptake tube to the steel-slag interface may be determined by an electrical probe. A chamber couples a vacuum source to the uptake tube, causing the slag to be funneled through the uptake tube until it is deflected by a baffle within the chamber. In an alternative embodiment the uptake tube terminates in a cap having a cross-sectional area substantially equal to the cross-sectional area of the ladle so that the slag is forced through the uptake tube into the chamber. The slag is received in a slag box forming the lower portion of the chamber. A cascade slag trap is provided for collecting that portion of the slag which manages to pass through the chamber. The vacuum source may be of such large capacity that it also provides a vacuum environment for a ladle degassing system.

摘要： A nozzle or nozzles for spraying cooling water are disposed at the lower end of a slag suction path. A cooling water down-flow passage is provided on the outer periphery of an inner tube which constitutes a slag suction path. A water sump is provided below the cooling water down-flow passage, the water sump being located lower than the each nozzle. A lower end opening of the cooling water down-flow passage is disposed lower than the each nozzle and is submerged in water in the water sump. The cooling water down-flow passage, except the lower end opening, is adapted to be closed up. When the cooling water down-flow passage is closed up, water in the passage is stopped by atmospheric pressure acting upon the surface of the water in the water sump, so that it is prevented from flowing down.

摘要： In removing slag by vacuum suction, an upward force is always applied which is greater than the force with which a suction head is attracted downward under the influence of its own weight and that of connected parts. During normal operation, a drive force is applied through a separate drive system to balance the upward force, thus keeping the suction head in the desired position. When the drive force fails, the upward force holds the suction head in the hazard-free raised position.
