Electric arc furnace for continuous melting of directly reduced iron or directly reduced iron ore

摘要

A direct-heat arc furnace for the production of molten iron by continuously melting and reducing directly reduced iron or directly reduced iron ore, which comprises electrodes fixed in position and a furnace body to be driven so that the relative position of arc spots at the tips of the electrodes and the surface of the molten material in the furnace move continuously, and in which the shape and moving path of the furnace body are such that the range of tapping port movement is minimized and the melting of the feed stock and the tapping of the molten iron are performed continuously.
