摘要： An aluminum alloy for making an extruded and brazed aluminum product, the aluminum alloy comprising, in weight percent, 0.10-0.20 Zn to improve corrosion resistance, 0.9-1.2 Mn, 0.03-0.10 Mg, the sum of Mg and Mn being at least 0.99 to maintain or improve strength, 0.15 to 0.30 Fe to control grain size, up to 0.15 Si, up to 0.03 Cu, up to 0.04 Ti, the balance being aluminum and unavoidable impurities. The alloy may be in the form of extrusion ingots or extruded and brazed aluminum products. A process for making an extruded and brazed aluminum product from the alloy involves homogenizing, extruding, optionally working, and brazing the alloy to form the product.

摘要： The invention relates to an aluminium smelter (1) which comprises a row (2) of electrolysis cells arranged transversely relative to the row (2), one of the cells comprising anode assemblies and electrical conductors for raising and connecting to the anode assemblies. The raising and connection conductors extend upwards along two opposing longitudinal edges of the cell. In addition, the aluminium smelter (1) comprises a first electrical compensation circuit (4) extending under the cells and capable of carrying a first compensation current (IC1) in the opposite direction to the electrolysis current (IE), and a second electrical compensation circuit (6) extending on one side of the row (2) and being capable of carrying a second compensation current (IC2) in the same direction as the electrolysis current (IE).

摘要： The present describes a process for producing a bauxite agglomerate comprising: providing a crude bauxite having a fine particle size and an initial weight % of water as a feed bauxite, optionally screening said feed bauxite or pre-screening at least part of said crude bauxite, optionally adjusting the weight % of water of the feed bauxite; providing a cement binder; mixing a feedstock bauxite based on said feed bauxite with the cement binder in at least one mixer under intensive mixing conditions producing a bauxite binder mixture; and curing the bauxite binder mixture for a cure time thereby allowing the cement binder through a reaction with the water in the bauxite binder mixture to cure and form the bauxite agglomerate. The process enhancing the value of crude bauxite, by producing a transportable agglomerated crude bauxite from a fine non-calcined bauxite. The bauxite agglomerate serving as an intermediate product for producing a smelter grade alumina.
