摘要： A process of manufacturing aluminum can body stock involving the following steps. A molten aluminum alloy is prepared, the alloy containing Mg in the range 1.1 to 1.5 % by weight, Mn in the range 0.4 to 0.9 % by weight, Cu in the range 0.2 to 0.4 % by weight, Fe in the range 0.2 to 0.7 % by weight, Si in the range 0.07 to 0.3 % by weight, all other elements each less than 0.05 % by weight to a maximum of 0.2 % for all other elements. The alloy is cast in a continuous strip casting process to produce a slab having a thickness of at least 9 mm. The slab is rolled using at least 83 % reduction to produce a re-roll strip. The re-roll strip is coiled to form a coil and the coil to cool is allowed to cool naturally. The re-roll strip is then annealed and cold rolled to a final gauge of between 0.26 and 0.4 mm, using a reduction of between 75 and 85 %, with no interanneal. The resulting strip can be used as can body stock having a 45 degree earing of less than 3 % and a yield strength after stoving of at least 265 MPa (38.5 ksi).

摘要： A new aluminium alloy containing (in wt.%): 0.2 - 0.5 Fe; 0.7 - 1.2 Si; 1.2 - 1.6 Mn; up to 0.3 Mg; up to 0.5 Cu; up to 0.2 Zn; up to 0.1 Ti is used to make the fins of heat exchangers particularly car radiators. The finstock has high post braze strength and thermal conductivity, and has a sufficiently electronegative potential as to be capable of acting as a sacrificial anode for the heat exchanger tubes. By virtue of the absence of Sn, In and Cr, these heat exchangers can be scrapped and melted for re-use.

摘要： A testing device is described for use in determining optimum operating conditions for a full size industrial continuous gravity settling unit and for the design of such settling unit. The testing device comprises an elongated, cylindrical settling column having concentric, inner and outer transparent cylindrical walls forming an annular space therebetween filled with transparent heat exchange liquid, with the inner wall defining a cylindrical settling cell. A cylindrical feedwell extends downwardly into the top end of the settling cell, an overflow outlet opening is provided in the inner wall at a location above the bottom end of said feedwell, a solids discharge opening is provided at the bottom of the settling cell and a rotating rake is provided at the bottom of the settling cell for compacting collected solids. The device also includes pump means for providing smooth, continuous flows of slurry and flocculant, mixing means for mixing together the slurry and flocculant, and means for measuring and controlling flow rates and temperatures. The testing device is utilized by observing the position and shape of a stream of agglomerated solids leaving the bottom of the feedwell of the settling column and adjusting the flow rate of at least one of the flow rate of the stream of suspended solids and the flow rate of the stream of flocculating agent to the settling column such that the stream of agglomerated solids leaving the feedwell displays hindered settling, and utilizing the adjusted flow rates of the suspended solids stream and the flocculant stream to determine the optimum operating conditions for an industrial settling unit.

摘要： A process of coating a heat-conductive strip article, e.g. aluminum or aluminum alloy strip (14) used in the automotive industry, with a solid wax-like coating material, preferably a wax-type lubricant. The process involves heating a solid wax-like coating material that melts in a temperature range of about 30 to 100 DEG C to form a melt having a viscosity in a range of about 50 centipoise or less and flowing the melt onto a moving surface of the strip article through an elongated slot (15) in a movable coating head having an extended surface adjacent to the slot to form a coating layer on the article. The coating head is pushed towards the surface of the strip article as the melt is flowed as a coating onto the surface from the slot (15) to reduce a coating thickness by pressing the extended surface of the coating head onto the coating as the coating is formed. The process allows a coating of a wax-like material to be formed to a desired thickness and yet allows the wax-like material to solidify shortly after application to the strip article (14) so that the strip can be coiled without providing a cooling run of undue length or special cooling devices.

摘要： A process of producing solution heat treated aluminum alloy sheet material comprises subjecting hot- or cold-rolled aluminum alloy sheet to solution heat treatment followed by quenching and, before substantial age hardening has taken place, subjecting the alloy sheet material to one or more subsequent heat treatments involving heating the material to a peak temperature in the range of 100 to 300 DEG C (preferably 130-270 DEG C), holding the material at the peak temperature for a period of time less than about 1 minute, and cooling the alloy from the peak temperature to a temperature of 85 DEG C or less. The sheet material treated in this way can be used for automotive panels and has a good "paint bake response", i.e. an increase in yield strength from the T4 temper to the T8X temper upon painting and baking of the panels.

摘要： A method of recovering an aluminum-containing metal (16) from a scrap material (14, 14') containing the metal and an organic contaminant, such as paper, plastics, lacquer, paint or oil. The method involves creating a fluidized bed (10) of solid particles, maintaining a zone of the bed at a temperature in the range of the melting point of the metal to 1000 DEG C, introducing the scrap material into the fluidized zone to cause decoating of the metal within a time in the range of 1 to 40 seconds, at least partially melting the metal, and removing the metal material from the fluidized bed. In this way, decoating and at least partial melting is achieved essentially at the same time for improved efficiency. Metals of different melting point may also be separated from each other by providing a series of temperature zones in the fluidized bed (or in a series of fluidized beds) of progressively increasing temperature. If a limited amount of oxygen is introduced into the bed, a combustible gas is produced that can be burned to extract its energy or can be stored for later use.
摘要翻译：一种从含有金属和有机污染物如纸，塑料，漆，油漆或油的废料（14,14'）回收含铝金属（16）的方法。该方法包括产生固体颗粒的流化床（10），将床的区域保持在金属熔点范围内的温度至1000℃，将废料引入流化区以引起脱色金属在1至40秒的范围内的时间内，至少部分地熔化金属，并从流化床除去金属材料。以这种方式，脱蜡和至少部分熔融基本上在同时实现以提高效率。通过在逐渐升高的温度的流化床（或一系列流化床）中提供一系列温度区，也可以将不同熔点的金属彼此分离。如果将有限量的氧气引入床中，则产生可燃烧的气体，其可以被燃烧以提取其能量，或者可以储存以备后用。
