  • Patent number: 8748524
    Abstract: The present invention relates to a heat crucible glue or coating for use in connection with refractory materials and ceramics. The glue or coating comprises 25 to 50 weight % silicon powder, 5 to 20 weight % SiC powder, 20 to 60 weight % formaldehyde resin or polyfurfuryl alcohol and 10 to 30 weight % of an organic solvent.
    Type: Grant
    Filed: October 13, 2011
    Date of Patent: June 10, 2014
    Assignee: Elkem Carbon AS
    Inventors: Bjorn Egeland, Alf Håberg, Johan Arnold Johansen, Stian Madshus
  • Patent number: 8535581
    Abstract: The present invention relates to an induction furnace for melting of metals that do not connect inductively in solid state. The induction furnace has a lining comprising a mixture of graphite and silicon carbide and has an electric conductivity higher than the electrical conductivity of the metal to be melted when metal is in solid state, but lower than the electrical conductivity of the metal to be melted when the metal is in molten state. The invention further relates to a lining for induction furnace and to a method for producing such lining.
