  • US Patent:
    7313160, Dec 25, 2007
  • Filed:
    Dec 14, 2005
  • Appl. No.:
    11/302960
  • Inventors:
    Ronald E. Gerhan - Avon Lake OH, US
  • Assignee:
    Graftech International Holdings Inc. - Parma OH
  • International Classification:
    H05B 7/144
    H05B 7/148
  • US Classification:
    373104, 373102, 373105
  • Abstract:
    A furnace's operating efficiency is improved by simultaneously monitoring various furnace operating parameters such that the monitored values may be collectively examined and correlated to determine if the furnace is sub optimally operating. In particular, the electrode current, hydraulic valve spool position, hydraulic fluid pressure, and electrode mast position of an electrical arc furnace are simultaneously monitored and correlated to determine if any unidentified sub optimal operating conditions are present. By improving the chances of detecting and correcting sub optimal operating conditions, the present invention improves the electrode consumption and overall efficiency of a furnace's operation.

  • US Patent:
    7386369, Jun 10, 2008
  • Filed:
    Aug 9, 2004
  • Appl. No.:
    10/914726
  • Inventors:
    Ronald Eric Gerhan - Avon Lake OH, US
  • Assignee:
    GrafTech International Holdings Inc. - Parma OH
  • International Classification:
    G05B 21/00
    G06F 19/00
    H05B 7/06
  • US Classification:
    700274, 700110, 373 88, 702 34
  • Abstract:
    A system is provided for recording information relating to the condition of electrodes in an electric arc furnace. An imaging apparatus is provided in a consistent position relative to an imaging station. Periodically, the electrode columns are removed from the furnace and moved to a position such that the electrode column is placed at the imaging station. Then an image of the electrode column is created with the imaging apparatus, and the images are stored in a memory of a computer for subsequent analysis.

  • US Patent:
    7991039, Aug 2, 2011
  • Filed:
    Nov 30, 2004
  • Appl. No.:
    10/999374
  • Inventors:
    Ronald E. Gerhan - Avon Lake OH, US
    Nicolas Lugo - Clarksville TN, US
    Dave A. Lehr - Franklin TN, US

  • Assignee:
    GrafTech International Holdings Inc. - Parma OH
  • International Classification:
    H05B 7/18
  • US Classification:
    373102, 373104, 373 60
  • Abstract:
    A system and method for monitoring the operating parameters of an electric arc furnace having a primary electrical circuit comprising a primary current transformer. The method includes monitoring the furnace's primary current transformer; collecting data therefrom; transmitting the collected data to a server having an operatively connected monitor; and displaying the collected data on the monitor in substantially real-time. The server also collects information about the performance of the furnace from a programmable logic computer and information entered manually by an operator at a furnace monitoring viewer system, which may also be displayed in substantially real-time on the monitor.

  • Method For Controlling Foaming Of Slag In An Electric Arc Furnace

  • US Patent:
    20070133651, Jun 14, 2007
  • Filed:
    Dec 14, 2005
  • Appl. No.:
    11/300688
  • Inventors:
    Ronald Gerhan - Avon Lake OH, US
    Nicolas Lugo - Clarksville TN, US
    Theodore Kurela - Hinckley OH, US
  • International Classification:
    F27D 17/00
  • US Classification:
    373009000
  • Abstract:
    A method for controlling the foaming of slag in an electric arc furnace is disclosed. The furnace comprises at least one electrode column. Current is applied to the electrode column, causing an arc to form between the tip of the electrode column and the scrap, melting the scrap. Impurities in the molten scrap metal rise to the surface forming slag. A meter determines the total harmonic distortion associated with the system. If the total harmonic distortion is greater than a predetermined set point, and the scrap metal is sufficiently molten, then a foaming agent is added thereto.

  • Abstract:
    A system and method is disclosed for monitoring graphite electrodes for use in an electric arc furnace includes receiving an electrode identifiers from a radio frequency identification (RFID) tag reader configured to interrogate RFID tags in the vicinity of an electric arc furnace (EAF), wherein the RFID tags are attached to electrodes. The electrode identifier is associated with EAF data collected from the EAF and the association is stored in a memory. The association is used for generating current and past operating parameters of the electric arc furnace for specific electrodes. Data for each specific electrode used in the EAF can also be collected for determining performance parameters for specific electrodes.
