摘要： Electrolytic cells for production of Mg or other metal lighter than the molten electrolyte comprise electrode assemblies of anode 28, cathode 26 and intermediate bipolar electrodes 30 with substantially vertical regions 39 between them. The intermediate bipolar electrodes have open-top channels 50 along their top edges. An electrolyte/metal mixture rising from the interelectrode regions by gas lift is transported along these channels, substantially undisturbed by rising gas, to a weir 20 and then to a metal collection chamber 18. The electrolyte surface is kept at a constant level, preferably by means of a vessel 22 submerged in electrolyte in the metal collection chamber, to or from which molten electrolyte can be transferred to alter the surface level.

摘要： In a process for producing anhydrous magnesium chloride, the following combination of steps: drying impure salt containing hydrated magnesium chloride; establishing a solution of the hydrated magnesium chloride; removing insoluble impurities; reacting the solution of hydrated magnesium chloride at substantially ambient temperature and pressure by feeding it into an ammonia saturated very low boiling point alcohol solution and in the presence of ammonium chloride while maintaining the last-mentioned solution saturated in ammonia thereby to form a precipitate of ammoniated magnesium chloride; separating the precipitate and heating it to obtain anhydrous MgCl.sub.2 and ammonia for recycling.

摘要： A belt cooling and guiding apparatus for a casting belt of a twin belt caster. The cooling and guiding apparatus comprises at least one nozzle having a support surface facing a reverse surface of the casting belt (a surface opposite to a casting surface in the casting mold), provided with a continuous slot in the support surface arranged transversely substantially completely across the casting belt. The slot allows for delivery of cooling liquid to the reverse surface of the belt in the form of a continuous film having uniform thickness and velocity of flow when considered in the transverse direction of the belt. This allows for even cooling transversely of the belt. The nozzle arrangement is also provided with a drainage opening for removal of cooling liquid downstream from the continuous slot, and a vacuum system associated with the drainage opening for applying suction to the drainage opening. One or more such cooling nozzles is provided at the entrance of the casting mold where uniform cooling is critical to the characteristics of the cast strip article.

摘要： A layer of liquid parting agent, and any solid detritus contained therein, is completely removed from a casting surface of a rotating belt after contact with molten metal. A new layer of liquid parting agent is applied to the casting surface thereafter and prior to renewed contact with the molten metal. The removal of used parting agent and the application of fresh helps to prevent the formation of surface blemishes and defects on the cast metal strip product. Such blemishes and defects can also be minimized by using an injector having a flexible tip used to inject the molten metal onto the casting surface and preferably one or more spacers to create a gap between the tip and the casting surface itself. The spacer is preferably a screen of wire strands orientated to minimize disruption of the new layer of liquid parting agent applied to the casting surface. By avoiding disruption of the new layer of liquid parting agent, surface blemishes on the cast product are minimized.

摘要： The invention provides apparatus for the production of a continuous uniform length of coherent metal. A cone 10 of atomized metal particles is deposited on a surface 12, which is continuously withdrawn in the form of a length of coherent metal 14. Shaping means 16 are provided to make the withdrawn deposit uniform along its length. The equipment is protected from the atmosphere by a hood 18 through which the length of metal is withdrawn through an aperture provided with a seal 20. Preferably, the deposit is of circular cross-section and is caused to rotate during withdrawal about its longitudinal axis. The equipment is suitable to form billet or rod or tube.

摘要： Molten metal, such as aluminum, is held within rigid refractory lining means beneath, above and alongside the metal while heaters keep the outside of the lining means at a predetermined temperature desired for the metal, the heaters being surrounded by thermal insulation and the whole being surrounded by a fluid-cooled support. An unusually effective embodiment is pipe, with a tubular refractory liner to carry flowing metal, surrounded by sheathed heating elements controlled to keep the exterior of the tube at least at about the predetermined temperature, with the thermal insulation wrapped around the heaters and the enclosing support being a water-jacketed steel pipe. The operation is essentially adiabatic with respect to the refractory liner, delivering the molten metal essentially at its original temperature, with unusual saving of heat energy. When the heated pipeline has been drained, only easily removed, paper-thin skulls of solid metal remain.
