摘要： A rotor coupling (1) for connecting a graphite rotor (37) to a drive shaft (12) of a rotary degassing machine comprises a cap (2) which fits over an end of the rotor and contains gripping means (3, 4) to retain the rotor in the cap. The arrangement avoids screw-threaded interconnection between the rotor and drive shaft which necessitates the forming of a screw-thread on the rotor, adds to the cost of rotor manufacture, and quickly wears with use. No, or minimal, special forming of the rotor is needed for engagement by the gripping means. A used rotor which has a worn or broken screw-thread may be held by the gripping means for the rotor to have further useful service. The gripping means preferably comprises two collet-form sleeves (3, 4) which fit one within the other inside the cap and have complementary tapered surfaces (22, 23) which co-operate upon relative axial movement of the sleeves, by means of screws or bolts (27), to cause the inner sleeve (3) to be compressed about the rotor to clamp it to the cap.
摘要翻译：用于将石墨转子（37）连接到旋转脱气机的驱动轴（12）的转子联轴器（1）包括盖子（2），该盖子（2）装配在转子的一端并包含夹紧装置（3,4）将转子保持在盖中。该装置避免了转子和驱动轴之间的螺纹连接，这需要在转子上形成螺纹，增加了转子制造的成本，并且在使用时迅速磨损。不需要或最小的特殊形状的转子需要通过夹持装置的接合。具有磨损或破损的螺纹的使用过的转子可以由用于转子的夹持装置保持以具有进一步的有用的服务。夹持装置优选地包括两个夹头形式的套筒（3,4），所述夹套形式的套筒（3,4）在帽子的另一内侧安装，并且具有互补的锥形表面（22,23），其通过套筒的相对轴向移动或螺栓（27），以使内套筒（3）围绕转子被压缩以将其夹紧到盖子上。

摘要： A process and apparatus are disclosed for recovering a non-ferrous metal, preferably aluminum and aluminum alloys, in molten coherent form from a charge of material to be processed containing the metal. The charge is introduced into a sealable furnace which is then sealed. The charge is agitated. A control parameter indicative of conditions inside said furnace is monitored and compared to a predetermined first condition for the parameter. A heat source is operated to heat the charge until the control parameter reaches the first condition. The operation of the heat source is then stopped. A controlled amount of oxidizing agent and an inert carrier is then introduced into the furnace. The control parameter is monitored and compared to a predetermined second condition for the parameter. The flow of the oxidizing agent and the carrier is controlled to maintain the control parameter at about the second condition. The molten metal is subsequently removed from the furnace.

摘要： A method of and apparatus for treating molten metal to achieve effective removal of such unwanted inclusions as gases, alkali metals, entrained solids, and the like. The method comprises introducing molten metal into a trough, such as the trough provided between a melting furnace and a casting machine, providing at least one mechanically movable gas injector submerged within the metal in the trough and injecting a gas into the metal in a part of the trough forming a treatment zone through the injector(s) to form gas bubbles in the metal while moving the injector(s) mechanically to minimize bubble size and maximize distribution of the gas within the metal. The injectors are preferably rotated and comprise a rotor body having a cylindrical side surface and a bottom surface, at least three openings in the side surface spaced symmetrically around the rotor body, at least one opening in the bottom surface, and at least one internal passageway for gas delivery and an internal structure for interconnecting the openings in the side surface, the openings in the bottom surface and the internal passageway. The internal structure is adapted to cause gas bubbles emanating from the internal passageway to break up into finer bubbles and to cause a metal/gas mixture to issue from the openings in the side surface in a generally horizontal and radial manner.
