ABSTRACT:
An electric arc furnace having a partially insulated electrode produces molten metal such as foundry iron from an iron source where little or no slag is produced. The furnace includes at least one insulated electrode assembly for immersing deep into the metal charge. The electrode assembly has an electrically conducting member coupled to an electrode. The electrode has a coupling member at the upper end for coupling with the electrically conducting member and a coupling member at the lower end for coupling with an adjacent electrode to form an electrode column. The coupling members can be an internally threaded recess in the ends thereof. An externally threaded coupling member can be threaded into the recesses of the electrodes for coupling two or more electrodes together.
