Abstract
A rectangular metallurgical furnace is provided with at least six electrodes which are symmetrically arranged in two rows along the longitudinal axis of the furnace. Each pair of electrodes form a single phase circuit. A transformer is also provided for each pair of electrodes to form bifilar conductor leads. The spacing between adjacent and opposite electrodes is adjusted to provide a continuous bath surface over a maximum horizontal cross section. Adjacent and opposite pairs of electrodes are located in the corners of imaginary squares.
