  • Publication number: 20130168889
    Abstract: An aggregate includes coke and titanium for introduction into metallurgical vessels for increasing the durability and for repairing the refractory lining. The aggregate has a content of titanium-containing compounds and a content of 10 to 98 wt.-% of coke-containing material, based on the total amount of aggregate, which contains no or only small amounts of less than 25 wt.-%, based on the coke containing material of substances being volatile at the temperatures present at a reaction site, whereby the aggregate is obtained by the combined coking of carbonaceous material and titanium-containing compounds.

  • Publication number: 20110154946
    Abstract: A method of producing foamed slag in an arc furnace by measured blowing of a carbon carrier by means of an oxygen carrier into the boundary layer between the slag and molten metal layers or into zones of the slag or molten metal layer adjacent to the boundary layer in an amount such that arc are enveloped at least by a foamed slag layer.

  • Patent number: 7820129
    Abstract: The invention relates to a method for producing carbon or HV graphite electrodes, in which a carbon carrier is mixed with a hydrocarbon-containing binder, and the mixture is subjected to a coking process and/or graphitization process, and one or more synthetic titanium compounds are additionally added to the raw materials. The titanium compound is preferably comprised of TiO2. Iron oxide can be added as an accompanying substance.

    Date of Patent: October 26, 2010
    Assignee: Sachtleben Chemie GmbH
    Inventors: Djamschid Amirzadeh-Asl, Dieter Fünders
  • Patent number: 6660673
    Abstract: In order to reduce wear on refractory linings due to corrosion and the infiltration of slags and molten metals, particulate materials containing TiO2 are added to the refractory products consisting of a mixture of aggregates and binding agents.
    Type: Grant
    Filed: July 24, 2000
    Date of Patent: December 9, 2003
    Assignee: Sachtleben Chemie GmbH
    Inventors: Djamschid Amirzadeh-Asl, Dieter Fünders
  • Patent number: 6460742
    Abstract: A process for reducing fume, dust and/or smoke emission in transferring molten metal, entailing: a) blanketing molten metal, preferably steel or iron with, at least, solid carbon dioxide; and b) allowing the carbon dioxide to sublime, thereby restricting free air access to the molten metal, and reducing fume, dust and/or smoke emission therefrom.
