  • Method of manufacture of phosphate-bonded refractories
    Patent number: 6740299
    Abstract: A method of manufacturing a phosphate-bonded refractory product entirely during the mixing cycle by reacting phosphoric acid and alumina derived from one or more sources of finely divided reactive alumina, for example &bgr;-alumina and/or alumina hydroxide to form a proto aluminum orthophosphate gel or paste binder in the pan of a high-intensity mixer at ambient temperatures.
    Type: Grant
    Filed: May 16, 2001
    Date of Patent: May 25, 2004
    Inventors: George F. Carini, George F. Carini, II

  • Method of manufacture of phosphate-bonded refractories
    Patent number: 6258742
    Abstract: A phosphate-bonded refractory composition consists of a size-graded mixture of refractory material, 3 to 5 weight percent based on the total weight of the batch of finely divided aluminium hydroxide, 4.22 to 8.37 percent by weight of the total weight of the batch of 75 to 85 percent phosphoric acid, the ratio of the aluminum in the aluminum hydroxide to phosphorus in phosphoric acid being about 1:1.

  • Continuous casting method and mold flux powders
    Patent number: 4312400
    Abstract: This invention relates to mold flux powders for the continuous casting of steel. The mold flux powders comprise a plurality of sequential melting systems forming successive melts each of which assimilates the ingredients of the next system into the melt. In this way, the desired fluidity is achieved in the mold flux at a rate required by the particular continuous casting process in which the flux is being used without resorting to an excessively low melting flux. At least one of the systems comprises a finely-divided glass.

  • Tundish flux powder
    Patent number: 4202692
    Abstract: This invention relates to a tundish flux for use with aluminium-killed steel consisting essentially of 31 to 75% by weight calcium carbonate, 4 to 14% alkali metal carbonate, up to 18% fluorspar, and 14 to 38% sodium fluoride. Preferably, the ingredients are finely-divided materials which are blended and agglomerated into pellets about one-quarter to one-half inch in diameter.

  • Continuous casting mold flux powers
    Patent number: 4190444
    Abstract: This invention relates to mold flux powders for the continuous casting of steel. The mold flux powders comprise a plurality of sequential melting systems forming successive melts and in turn taking the ingredients of the next system into solution. In this way, the desired fluidity is achieved in the mold flux at a rate required by the particular continuous casting process in which the flux is being used without resorting to an excessively low melting flux. At least one of the systems comprises a finely-divided glass.
