  • MANUFACTURED SPRAY COOLING WATER FOR GRAPHITE ELECTRODES
    Publication number: 20240384935
    Abstract: Systems and methods for cooling a graphite furnace electrode with manufactured spray cooling water for high-temperature furnace electrodes. The manufactured spray cooling water can be engineered to have desired properties and/or components that improve sidewall oxidation losses. The manufactured spray cooling water can be produced by modifying a water source that is used to cool the electrodes to provide a more pure water and optionally adding an additive to the more purified water.

  • Methods of protecting furnace electrodes with cooling liquid that contains an additive
    Patent number: 12150230
    Abstract: A method for forming a protective antioxidative barrier on the furnace electrodes using a chemically altered cooling liquid containing an antioxidant additive. This method can be applied to electrodes used in electric arc furnaces and ladle metallurgy furnaces. The method can involve spraying the cooling liquid onto the electrode, thereby forming the protective antioxidative barrier and reducing the oxidation of the electrode.

  • SYSTEMS AND METHODS TO EVALUATE SPRAY COOLING COVERAGE OF GRAPHITE FURNACE ELECTRODES
    Publication number: 20240377137
    Abstract: Methods and systems are described for evaluating the coverage of cooling water that is sprayed onto the surface of a graphite furnace electrode. The surface of the electrode can be sprayed with cooling water that includes an additive, and the sprayed surface can be visually inspected or imaged to assess the cooling water coverage of the electrode surface. One or more corrective measures can be taken to improve the spray coverage if it is deemed to be inadequate.
