摘要： The present invention is concerned with a process for the preparation of sintered calcium aluminates that can generally be used as a protective cover for liquid metals, and particularly steel, and the process comprising the steps of mixing calcium oxide, or its precursor, particles and aluminum dross residue, such as NOVAL.TM.; calcining the resulting mixture; maintaining a calcining temperature of 1200.degree. C. or higher for approximately 5 minutes or more which is sufficient to form a friable sintered product rich in calcium aluminates; and recovering the sintered product after cooling. Optionally, calcium fluoride, or other fluoride can be added to the starting mixture, if it is not already contained in the dross residue.

摘要： There is provided a filtration and distribution device for a molten metal, which is in the form of a bag having parts made of a solid heat-resistant fabric and open areas made of an open weave heat-resistant fabric. At least some of the parts made of the solid heat-resistant fabric are replaced by rigid parts made of a moldable or thermo-formable composite consisting of an open weave heat-resistant fabric embedded into a matrix made of a heat-resistant inorganic material compatible with the open weave heat-resistant fabric. Preferably, the open weave heat-resistant fabric forming the open areas of the bag, is made of yarns that are rigidified and protected by application thereto of a heat-resistant coating. This coating is preferably made of a heat-resistant inorganic material applied by spraying or dipping after the yarns are weaved. The rigidification can be achieved naturally or by thermal treatment. There is also provided a distribution device for a molten metal, which comprises a hollow body provided with an outlet connectable to a molten metal feed pipe and at least one outlet through which the molten metal fed into the body may escape. This hollow body is made of the very same moldable and thermo-formable composite already mentioned hereinabove.

摘要： Disclosed is a free flowing dry back-up material which comprises: from 67 to 96% by weight of fly-ash; from 2 to 15% by weight of a heat sensitive binder such as boric acid; from 2 to 7% by weight of a non-wetting agent such as calcium fluoride; from 0 to 10% by weight of a heat expandable material, viz. a material expandable as a function of the temperature such as vermiculite or graphite; and from 0 to 1% by weight of a dust suppressant such as kerosene. This material which is useful in particular in the aluminum industry has the advantages of being water free and free flowing, such avoiding the use of vibrator to position it into a shell. It also has a low density and a low thermal conductivity. Moreover, it is organic free as compared to the existing materials which use an organic binder to ensure a low temperature set; and it sets at a temperature lower than 400° F.

摘要： A metal distribution system for the simultaneous production of a plurality of logs or round billets from molten metal comprising: 1) a trough for the introduction of molten metal; 2) a plurality of side streams extending from the trough and each of the side streams including a plurality of opposing apertures each of the apertures including a thimble for the shaping of molten metal passing through the trough and the side streams and into the thimbles. A uniform flow of molten metal into the side streams and the individual apertures is provided by the controlled negative angular orientation of the most upstream opposing pair of apertures thereby providing relative uniformity of the temperature of molten metal reaching each of the plurality of apertures. A unique unitized thimble configuration and trough damming arrangement are also described.

摘要： Apparatus for and a method of measuring the temperature of molten aluminum or aluminum alloys. The apparatus comprises a temperature measuring device, usually a thermocouple, contained within a protective tubular sheath, the sheath enclosing the temperature measuring device at least to a point above the point of maximum immersion in molten aluminum during use of the apparatus. The sheath comprises at least one inner layer closed at one end, and an outer layer, the outer layer being made of steel or cast iron, and the inner layer being made of a continuous refractory material. The outer layer and the at least one inner layer are free of discontinuous (refractory) refractory materials between them. The continuous refractory material may be, for example, a carbon fiber-reinforced carbon or graphite fiber-reinforced calcium silicate refractory, and is resistant to failure in, i.e. penetration by, molten aluminum or aluminum alloy. The apparatus is long-lived and durable and does not contaminate the molten metal when it fails.

摘要： A method of recovering an aluminum-containing metal from a scrap material containing the metal and an organic contaminant, such as paper, plastics, lacquer, paint or oil. The method involves creating a fluidized bed of solid particles, maintaining a zone of the bed at a temperature in the range of the melting point of the metal to 1000.degree. 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.
