发明名称 Process for obtaining fluid light metal from a dispersed mixture
摘要 Process for obtaining a metallic phase from a dispersed mixture composed of one of (a) at least one metal selected from the group consisting of a light metal or an alloy of the at least one metal, and mixtures thereof, and (b) at least one non-metallic phase composed of at least one member selected from the group consisting of at least one oxide, an oxide compound, and other compounds of the at least one metal at higher temperatures. The process includes introducing the dispersed mixture into a metallurgical vessel; at least one of heating and adjusting a temperature of the dispersed mixture to between 20 and 250 DEG C. above the liquidus temperature of the metallic phase; rotating the metallurgical vessel to homogenize the dispersed mixture and to produce a pourable dispersed mixture; uniformly distributing the pourable dispersed mixture around a rotational axis of the metallurgical vessel; and increasing a radial acceleration of the pourable dispersed mixture of at least 1 g. The process further includes maintaining the radial acceleration for at least 0.015 hours to one of separate the metallic phase of the pourable dispersed mixture from the non-metallic phase of the pourable dispersed mixture and de-metallize the pourable dispersed mixture; decreasing the radial acceleration to a value of 0 in a span of time greater than 0.03 hours; pouring the metallic phase as a fluid out of the metallurgical vessel; and after pouring the metallic phase out of the metallurgical vessel, removing the at least one non-metallic phase from the metallurgical vessel.
