CURRENT SUPPLY FOR ELECTRODES OF ELECTRO-SMELTING FURNACES

摘要

A current feed for an electrode of an electric smelting furnace. The current feed conductors lead to the electrode above the furnace hearth, and a current feed element surrounds the electrode and is arranged coaxially to the electrode and concentrically to the current feed conductors. Contact jaws are arranged concentrically to the electrode. The current-conducting cross section of the current feed element varies continuously from a maximum on the side away from the furnace axis to a minimum on the side adjacent to the furnace axis.
