Abstract:
1. A metallurgical reactor comprising: a shell comprising a sidewall and a bottom, wherein the shell is configured to contain a molten material; at least one consumable electrode fed through an opening of the shell and into the molten material, wherein the consumable electrode is configured to provide an operating current to the molten material, and wherein the opening is located in the sidewall or the bottom of the shell; a current clamp configured to conduct the operating current to the electrode; wherein the current clamp is in contact with the electrode as the electrode is fed; and wherein the current clamp comprises at least one internal channel configured to circulate a cooling medium; an electric isolation ring disposed between the electrode and the opening, wherein the electric isolation ring is configured to electrically isolate the sidewall or the bottom; a first ring surrounding the electrode and connected to the sidewall or the bottom configured to press the current clamp against the electrode; and a second ring surrounding the electrode and connected to the sidewall or the bottom configured to press the current clamp against the sidewall or the bottom, wherein a front part of the current clamp extends into an opening between the surface of the electrode and the isolation ring.
