Abstract
Metallurgical reactors having cooling capability and electrode feed capability are disclosed. The reactors may include a shell having a sidewall and a bottom, where the shell is adapted to contain a molten material. The reactors may include at least one consumable electrode protruding through an opening of the shell and into the molten material. The reactors may include a current contact clamp configured to conduct operating current to the electrode, where the current clamp is in contact with the electrode, and where the current clamp comprises at least one internal channel, wherein the internal channel is configured to circulate a cooling medium. The reactors may include an electric isolation ring disposed between the electrode and the opening of the shell, wherein the electric isolation ring is configured to sealingly engage the electrode and the opening so as to restrict flow of the molten material out of the shell.
