Abstract:
1. A microwave iron-making furnace, comprising: a reactor having a casing and a blanket for covering a side, bottom, and top surface of the casing; a microwave oscillator for irradiating an interior of the reactor with microwaves; a raw material powder supply apparatus for supplying a raw material powder containing iron ore and a carbon source to the interior of said reactor; and an extraction part for extracting molten iron from the reactor, wherein said microwave oscillator directs, into the interior of the reactor, microwaves that have been imparted with directivity using a helical antenna, wherein the raw material powder in the reactor is irradiated and heated by the microwaves from the microwave oscillator that have been imparted with directivity by the helical antenna, wherein the iron ore is reduced using the carbon source, and wherein the molten iron is obtained.
