To provide a method, in which iron oxide is efficiently reduced to a metallic iron at the time of obtaining the metallic iron by heating and reducing the iron oxide of iron ore, etc., together with carbon quality reducing agent of carbonaceous material, etc., and also, the high quality metallic iron can efficiently be produced as molten iron by melting and smoothly separating slag component mixed as gangue component, etc., in the iron oxide source of iron ore, etc., and an equipment thereof.

At the time of producing the metallic iron by heating and reducing the formed body of iron oxide containing the carbon quality reducing agent, the metallic iron outer shell is produced and grown by heating and reducing while continuously shifting under condition of laying the formed body on an iron-made band plate 1, and the reduction is progressed until the iron oxide does not substantially exist. Further, the slag is produced in the inner part of the formed body, and after melting the formed body together with the iron- made band plate 1 by further heating this formed body is separated into the molten slag S and the molten iron F.
