摘要： The invention relates to a process of decontaminating metal (especially aluminum or aluminum alloy) scrap contaminated with organic material. The problem with such methods is that undue oxidation of the metal may take place as the decontamination proceeds, leating to reduced recovery rates. The process involves heating the scrap in a fluidized bed of solid particles fluidized by a fluidizing gas to a decontaminating temperature high enough to consume the organic material but below the melting point of the metal. The heating step is carried out in the presence of a protective material which protects the aluminum or aluminum alloy against substantial oxidation while the scrap is held in the bed at the decontaminating temperature. Preferred protective materials include organic and inorganic fluorine-containing compounds, particularly AlF3. The process is particularly effective for the treatment of aluminum alloys containing magnesium, which are especially susceptible to oxidation. Scrap decontaminated in this way can be subjected to conventional metal recovery processes, e.g. metal melting, and provide high recovery rates of the metal. The process of the invention can also be used for protecting metal (particularly aluminum and alloys thereof) against excessive oxidation during heat treatments other than decontamination. The invention also relates to the treatment of briquettes of compacted scrap without the need for protection from oxidation and without the need for prior shredding or grinding.
摘要翻译：本发明涉及用有机材料污染的金属（特别是铝或铝合金）废料的净化方法。这种方法的问题是随着去污进行，可能发生金属的过度氧化，从而降低回收率。该方法包括将通过流化气体流化的固体颗粒的流化床中的废料加热至高达足以消耗有机材料但低于金属熔点的去污温度。加热步骤在保护材料的存在下进行，该保护材料保护铝或铝合金免于显着氧化，同时废料在净化温度下保持在床中。优选的保护材料包括有机和无机含氟化合物，特别是AlF 3。该方法对于处理特别容易氧化的镁的铝合金特别有效。以这种方式净化的废料可以经受常规的金属回收方法，例如金属熔化，并提供高回收率的金属。本发明的方法还可以用于保护金属（特别是铝及其合金），以防止除去去污以外的热处理过度氧化。本发明还涉及对压实废料的压块的处理，而不需要防止氧化，并且不需要先前的粉碎或研磨。

摘要： A process of producing granules of a reactive metal. The process comprises providing a source of molten reactive metal (41), forming discrete droplets (53) of the molten metal, contacting the droplets while still substantially molten with a fluidized bed of particles (12) maintained at a temperature substantially below the solidus temperature of the metal and freezing the droplets as discrete granules of the reactive metal in the fluidized bed. The invention also provides apparatus for carrying out the method and product produced by the method, including a magnesium-containing additive for aluminium alloying. The use of a fluidized bed for cooling and freezing the droplets avoids problems encountered in prior methods and also makes it possible to provide coatings of various kinds on the surfaces of the granules, if desired.

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.
