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.

摘要： A multibath metal Mg electrolyzer which produces metal Mg in a plurality of electrolytic cells (1, ..., 1). The current efficiencies of the electrolytic cells (1, ..., 1) are improved and the unit power cost is lowered. In order to send Cl2 gas which is a by-product in the electrolytic cells (1, ..., 1) to a refining apparatus, the gas is sucked from the electrolytic cells (1, ..., 1) by a blower (9) provided in a main pipe (8). Automatic valves (11) are provided in branch pipes (7, ..., 7) which are branched out of the main pipe (8) and to which Cl2 gas is introduced from the electrolytic cells (1, ...,1). The automatic valves (11) are of gate-type and their positioners are of pneumatic driving/controlling type. The suction pressures of Cl2 gas from the electrolytic cells (1, ..., 1) are measured and the openings of the automatic valves (11, ..., 11) are automatically controlled so that the measured pressures may be target values.

摘要： An aluminum alloy strip useful for can stock having a thickness of less than or equal to about 30 mm, and containing large (Mn,Fe)Al6 intermetallics as principal intermetallic particles in said strip. The intermetallic particles have an average surface size at a surface of the strip and an average bulk size in a bulk of the strip, the average surface size being greater than the average bulk size. The strip article may be produced by supplying a molten aluminum alloy having a composition consisting, in addition to aluminum, essentially by weight of: Si between 0.05 and 0.15 %; Fe between 0.3 and 0.6 %; Mn between 0.6 and 1.2 %; Mg between 1.1 and 1.8 %; Cu between 0.2 and 0.6 %; and other elements: less than or equal to 0.05 % each element with a maximum of 0.2 % for the total of other elements; and casting the molten alloy in a continuous caster having opposed moving mould surfaces to an as-cast thickness of less than or equal to 30 mm. The moving mould surfaces have a surface roughness of between 4 and 13 mu m, substantially in the form of sharp peaks, and heat flux is extracted from the metal at a rate that results in the production of an interdendritic arm spacing of between 12 and 18 mu m at the surface of said strip. The strip may then be processed to final thickness by means of rolling and annealing steps.

摘要： The invention relates to a process of recovering a non-ferrous metal from a dross containing the same. The process involves introducing into a furnace (preferably a rotary furnace) the dross and a coalescing aid for the metal, heating the dross and fluoride compound to a treatment temperature above the melting point of the metal, using a heating device which substantially maintains a non-oxidizing atmosphere in the furnace, agitating the dross until it reaches the treatment temperature, removing the molten metal thereby separated from a solid dross residue and removing the solid dross residue from the furnace. The coalescing aid is fluoride salt or mixture that remains substantially solid at the treatment temperature, for example, cryolite, recovered cryolite, AlF3 or NaF, or a mixture thereof. The salt or mixture remains in the dross during the process and does not make the dross become sticky, thus avoiding agglomeration of the dross particles. The use of the fluoride improves the rate of recovery of the metal content of the dross without producing environmental difficulties either during the heating operation or during the disposal or use of the dross residue.
摘要翻译：本发明涉及从含有该金属的浮渣回收有色金属的方法。该方法包括向熔炉（优选旋转炉）中引入浮渣和用于金属的聚结助剂，使用加热装置将浮渣和氟化物加热到高于金属熔点的处理温度，该加热装置基本上保持非金属，在炉中搅拌氧化气氛，直至达到处理温度，除去熔融金属，从固体渣渣中分离，并从炉中除去固体渣渣。聚结助剂是在处理温度下保持基本上固体的氟化物盐或混合物，例如冰晶石，回收的冰晶石，AlF 3或NaF，或其混合物。在该过程中，盐或混合物保留在渣滓中，并且不会使浮渣变粘，从而避免浮渣颗粒的团聚。氟化物的使用提高了浮渣的金属含量的回收速率，而不会在加热操作期间或在处理或使用渣渣期间产生环境困难。

摘要： Process and apparatus for continuous casting of metal strip in which 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 the metal, and in which 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. The invention also relates to the molten metal injector having a flexible tip and optionally provided with spacer elements.

摘要： A process and control system for controlling a rotary calcining kiln (10) having a feed material inlet (12) material to be calcined, a calcined product outlet (13) and a high temperature zone in which said material is calcined, the high temperature zone being movable within the rotary calcining kiln (10) according to changes in operational control variables of the rotary calcining kiln. The process comprises measuring temperatures within the rotary calcining kiln at various positions spaced from each other along the rotary calcining kiln in a region overlapping a predetermined desired position for the high temperature zone, and adjusting the control variables to move the high temperature zone to the desired position when the high temperature zone deviates from the desired position. In the process, the temperatures are measured by thermocouples (Th) having thermocouple junctions (26) protected by heat and abrasion resistant sheaths (27), preferably made of alumina/silicon carbide ceramics, positioned within the rotary calcining kiln.

摘要： A method and apparatus are disclosed for continuously drying, preferably with agglomeration and/or coating and sizing, and separating a solid product from a liquid feed material, especially bauxite slurry which passes through a very sticky phase during drying, without significant encrustation of the equipment used. The method comprises: spraying a liquid bearing solid material upwardly into a drying zone, feeding a drying gas into the drying zone from below the spraying liquid in substantially parallel flow, removing the mixture of the drying gas and entrained dried particles from the drying zone, separating the entrained dried particles from their mixture with the drying gas, returning the separated dried particles to the drying zone, and collecting the dried particles, characterized by arranging for the formation of a slower moving boundary layer within the feeding of the drying gas, through which boundary layer dried particles are allowed to fall under gravity to be collected, and by collecting the dried particles continuously from below the spraying liquid.
