  • Equipment for distribution and feeding of charge and fuel in shaft furnaces of rectangular cross section
    Patent number: 6800113
    Abstract: The present invention refers to an equipment for feeding and distributing charge and fuel in furnaces of rectangular cross section, comprising movable feeding tubes to distribute along the longitudinal section and the cross section of the furnace, both a charge comprised of self-reducing agglomerates, ore, scrap or any other metallic material, and solid fuels of any kind.
    Type: Grant
    Filed: June 28, 2001
    Date of Patent: October 5, 2004
    Assignee: Startec Iron LLC
    Inventors: Marcos de Albuquerque Contrucci, Pedro Henrique Carpinetti Costa
  • Modular furnace
    Patent number: 6692688
    Abstract: A modular apparatus for the production of molten metal by self reduction of agglomerates of metal oxide or of prereduced metal, which may be iron. The apparatus includes a plurality of connected cells of identical size and construction. Each apparatus is connected to equipment for supplying the agglomerates for reduction or melting and refining within a reduction chamber or melting chamber, respectively, of each cell.
    Type: Grant
    Filed: March 20, 2001
    Date of Patent: February 17, 2004
    Assignee: Startec Iron, LLC
    Inventors: Marcos de Albuquerque Contrucci, Pedro Henrique Carpinetti Costa, Edmar Saul Marcheze
  • Method for recovery of metals having low vaporization temperature
    Patent number: 6517603
    Abstract: A method for reducing metal oxides in a shaft furnace. A charge of metal oxide and a reductant is reacted in the furnace to produce a primary metal of the metal oxide and an additional secondary metal. The temperature of the off gas from the reaction is controlled to prevent condensing of the secondary metal so that it remains in the off gas for separation therefrom.
