Definitions

  • the invention relates to melting and heating furnaces with direct current plasma heating.
  • the contact electrode In the case of plasma melting furnaces with high currents, the contact electrode is subject to particularly severe thermal wear, which limits its durability.
  • the aim of the invention is. To create contact electrodes for melting and heating furnaces with DC plasma heating and high currents, preferably in the range of 10 to 40 kA, with a long service life, favorable heat transfer conditions and low material consumption.
  • the object is achieved in that the flow body made of a corrosion-resistant material ensures uniform heat dissipation over the entire end face of the contact electrode, a temperature sensor is located below the end face of the contact electrode, which signals exceptional thermal loads and a steel head as a wearing part with the end face of the Contact electrode is metallically connected.
  • a steel head 2 designed as a wearing part is metallically connected to the contact electrode 1.
  • the flow body 4 which is due to the special design of its forehead surface 5 causes uniform cooling of the end face 6 of the contact electrode 1.
  • a temperature sensor 7 is located below the end face 6 for signaling unusual thermal loads.
