  • Method for direct reduction of metal oxide to a hot metallized product in solid form
    Patent number: 4251267
    Abstract: A method for the continuous direct reduction of metal oxides, ores, etc. to a hot metallized product in solid form. A unique gas seal is employed to prevent the leakage of reduction gas from the bottom of the closed shaft furnace when the product is being discharged which does not affect the discharge temperature of the product.
    Type: Grant
    Filed: August 24, 1979
    Date of Patent: February 17, 1981
    Assignee: Midrex Corporation
    Inventors: Donald Beggs, Robert M. Escott
  • Briquet strip breaker
    Patent number: 4196891
    Abstract: Apparatus for separating a strip of briquets issuing from a briquetting machine into individual briquets by bending the briquet strip both longitudinally and transversely to break the connections between adjacent briquets. The apparatus includes a carrying conveyor having arcuate, waveform or sawtooth conveyor slats and a conforming conveyor having conveyor slats with a cross section which mates with that of the carrying conveyor. The conforming conveyor forces the briquet strip to conform to the slat configuration of the first conveyor and to pass around a pivot means which breaks or separates the strip into individual briquets.
    Type: Grant

  • Briquet sheet breaking by cooling and bending
    Patent number: 4165978
    Abstract: Apparatus for separating a sheet of briquets issuing from a briquetting machine into individual briquets by bending the briquet sheet both longitudinally and transversely to break the connections between adjacent briquets. The apparatus includes a carrying conveyor having arcuate, waveform or sawtooth conveyor slats and a conforming conveyor having conveyor slats with a cross section which mates with that of the carrying conveyor. The conforming conveyor forces the briquet sheet to conform to the slat configuration of the first conveyor and to pass around a pivot means which breaks or separates the sheet into individual briquets.
