An increase in the power of ferroalloy furnaces also increases the current in the electrodes and, to a lesser extent, increases furnace voltage as well. There is a deterioration in the power factor and electrical efficiency in this case, the reason being a decrease in the resistance of the bath. Studies have shown that the power of furnaces used to make manganese ferroalloys can be increased by increasing bath resistance and voltage if the spacing of the electrodes and the distance between them and the bath are also both increased. These changes will improve the energy parameters of the smelting operation.
