Abstract

Provided are an apparatus for manufacturing molten steel and a method for manufacturing molten steel using same. The apparatus for manufacturing molten steel includes a rotary kiln configured to reduce iron ore to form reduced iron, and an electric furnace receiving the reduced iron manufactured in the rotary kiln in order to manufacture the molten steel. The rotary kiln includes a body part into which the iron ore is moved and a in which the iron ore is reduced. A loading hole through which raw material and fuel are loaded, and a gas discharge hole for discharging gas, are defined in one side of the body part; and a discharge hole for discharging the reduced iron, and a combustion part in which pulverized coal injection and combustion are performed, are disposed in the other side of the body part. Also, the body part has a plurality of air inflow holes through which air is introduced.
