  • METHOD FOR PRODUCING FOAMED SLAG
    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.

  • Method for improving the durability of carbon or graphite electrodes by using Tio2—containing products
    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.

  • Process for reducing dust emissions of a blast furnace
    Patent number: 5683652
    Abstract: A process for reducing dust emission and free air access in the tapping region of a blast furnace by applying CO.sub.2 in a solid and/or gaseous state to the molten material and or the runners and vessels associated therewith. This process reduces dust emissions, nitriding of the product and energy costs associated with conventional dust reduction operations as well as wear of the refractory materials.
