- 3. Apparatus according to claim 2 wherein said openings are elongated slots.
- 4. Apparatus according to claim 2 wherein said openings are formed by internal nipples mounted in the wall of said plug and extending upwardly into the interior thereof.
- 5. Apparatus according to claim 1 wherein the fluid flow openings of said plug are lateral openings interconnecting the interior of said plug and the interior of said reactor.
- 6. Apparatus according to claim 1 wherein the wall of said plug is provided with a plurality of relatively large openings to facilitate removal of particulate ore from the interior thereof.
- 7. Apparatus for the gaseous reduction of metal ores comprising a reactor adapted to contain a bed of particulate ore to be reduced and a discharge port near the bottom thereof through which the reduced ore can be discharged, a hollow, substantially frusto-conical, upwardly converging closure plug mounted for swinging movement from a reactor-closing position within said port to a reactor-dischsarge position away from said port, actuating means for moving said plug between said two positions, and a gas supply conduit extending through the wall of said reactor and having a discharge end positioned to deliver gas to said plug when said plug is in its reactor-closing position, said plug having a gas inlet nipple that extends into said supply conduit and is withdrawn therefrom when said plug moves from its reactor-closing to its reactor-discharge position.
- 8. Apparatus according to claim 7 wherein said actuating means comprises a system of pivoted levers connected to said plug.
- 9. Apparatus according to claim 8 wherein said system of pivoted levers includes a hydraulic power cylinder for actuating said lever system to swing said plug toward and away from said reactor.
- 10. A removable closure for the bottom discharge port of a gaseous reduction reactor for reducing metal ores comprising a hollow, substantially frusto-conical upwardly converging closure plug defining a substantially frusto-conical chamber therein, said plug having an inlet connection for a cooling or heating fluid and a plurality of lateral openings through the frusto-conical wall of said plug through which said fluid can flow to the interior of said reactor.
- 11. A removable closure according to claim 10 wherein said openings are elongated slots.
- 12. A plug according to claim 10 wherein said openings are formed by nipples mounted in the wall of said plug and extending upwardly into the interior thereof.
- 13. A removable closure according to claim 10 wherein the wall of said plug is provided with a series of relatively large openings to facilitate removal of particulate material from the interior thereof.
- 14. A removable closure according to claim 10 wherein the wall of said plug is provided with a hinged door to facilitate removal of particulate material from the interior of said plug.
- 15. A removable closure for the bottom discharge port of a gaseous reduction reactor for reducing metal ores comprising a hollow, substantially frusto-conical plug defining an unobstructed frustro-conical chamber and adapted to be positioned within and to seal said discharge port, said plug having an inlet connection for a cooling or heating fluid and a plurality of lateral openings through the frusto-conical wall of said plug interconnecting the interior of said plug and the interior of said reactor through which said fluid can flow to the interior of said reactor, said openings of said plug being elongated slots and the wall of said plug being provided with a series of relatively large openings to facilitate removal of particulate material from the interior thereof.
- 16. A removable closure for the bottom discharge port of a gaseous reduction reactor for reducing metal ores comprising a hollow, thin-walled, substantially frusto-conical plug defining an unobstructed frustro-conical chamber and adapted to be positioned within and to seal said discharge port, said plug having an inlet connection for a cooling or heating fluid and a plurality of lateral openings formed in said thin wall and interconnecting the interior of said plug and the interior of said reactor through which said fluid can flow to the interior of said reactor, said openings of said plug being elongated slots and the wall of said plug being provided with a series of relatively large openings to facilitate removal of particulate material from the interior thereof, and said wall also being provided with a hinged door to further facilitate removal of particulate material from the interior of said plug.
- 17. Apparatus for the gaseous reduction of metal ores comprising a reactor adapted to contain a bed of particulate ore to be reduced and having a discharge port near the bottom thereof through which reduced ore can be discharged, a hollow, substantially frusto-conical, upwardly converging plug constructed and arranged to be positioned within and to seal said discharge port, said plug having an inlet connection for a cooling or a heating fluid and a plurality of openings through which said fluid can flow to the interior of said reactor, and a fluid supply conduit extending through the wall of said reactor and having a discharge end within said reactor, said plug having a gas inlet nipple that extends into said supply conduit and is withdrawn therefrom when said plug is removed from said reactor.
- 18. Apparatus for the gaseous reduction of metal ores comprising a reactor adapted to contain a bed of particulate ore to be reduced and having a discharge port near the bottom thereof through which reduced ore can be discharged, a hollow, upwardly converging plug having a thin, substantially frusto-conical wall defining an unobstructed frusto-conical chamber, said frusto-conical wall extending uninterruptedly between opposite ends of said plug, said plug being constructed and arranged to be positioned within and to seal said discharge port and having an inlet connection for a cooling or heating fluid, said plug also having a plurality of openings formed therein through which said fluid can flow from the interior of said plug to the interior of said reactor, and a fluid supply conduit extending through the wall of said reactor and having a discharge end within said reactor, the inlet connection of said plug being positioned to register with the discharge end of said supply conduit when said plug is positioned in said discharge port.
