CURRENT-CONDUCTING ARM FOR AN ELECTRIC ARC FURNACE

摘要

A current-conducting arm (10) for conducting a current from at least one cable supports (9) to an electrode in an electric arc furnace comprising an arm housing (14) having a U-shaped base channel member (16) and a U-shaped top channel member (18). Both channel members (16, 18) have a first and second wall, with the top channel member (18) being inverted such that the first wall of the top channel member (18) can be joined with the first wall of the base channel member (16), and the second wall of the top channel member (18) can be joined with the second wall of the base channel member (16). The arm housing (14) therefore has four annular corners to improve the conduction of current through the arm housing (14) to the electrode. Moreover, a laser pointer (52) is included for guiding the positioning of the arm housing (14) in the electric arc furnace.
