    摘要: An annularly shaped piece (28) formed from refractory material is provided for a tundish (1) for continuous casting of metals for enclosing a plasma torch (18) for heating liquid metal (4). The interior wall (29) of the annularly shaped piece defines a space which widens with progression toward the bottom, the piece having an upper opening (30) and a lower opening and accommodating penetration of the lower end region of the torch (18) into the space. The annularly shaped piece (28) is fixed to a cover (24) or to the refractory walls (3) of the tundish (1), and/or is fixed to one or more dividing walls (10) which delimit a heating compartment (13) in the interior of said tundish (1), wherewith the space defined by the interior wall (29) of said piece (28) widens with progression toward the bottom of the tundish (1). The annularly shaped piece (28) provides a more durable enclosure for the plasma torch (18), and enhances the torch's efficiency by better focusing the torch radiation onto molten metal in the tundish (1).

    摘要: The invention provides an autoclave configuration for pressure leaching lateritic ores at elevated temperatures. The autoclave configuration includes at least one primary autoclave. The primary autoclave includes a slurry inlet port for receiving slurries of lateritic ore from a lateritic slurry supply, an acid inlet port for receiving leaching acids, an agitation means for agitating the slurries of lateritic ore, and an outlet port for removing partially leached slurries of lateritic ore. A multi-compartment autoclave follows the primary autoclave. The multi-compartment autoclave is divided into at least two chambers connected in series. The chambers contain a means for agitating the partially leached slurries and divider walls for separating the chambers. An inlet port is connected to the first of the chambers for receipt of the partially leached slurries. An outlet port is connected to the last of the series of chambers for removal of the finally leached slurries. A bypass conduit is connected to the lateritic slurry supply and the multi-compartment autoclave. The bypass conduit is for periodically isolating the primary autoclave for removal of scale while leaching lateritic ore in the multi-compartment autoclave.
