ABSTRACT:
An electric arc furnace of the closed type for melting metals, having three heating electrodes and equipped with raw material charging inlets and a tapping hole in the furnace body. The three electrodes are arranged in a substantially straight line, and the raw material charging inlets are arranged in the furnace trunk or body so as to permit raw materials in chip form to be fed into the furnace in parallel with the line of the three electrodes. The raw material charging inlets also serve to exhaust dust and smoke produced in the course of operating the electric furnace.
