METHOD FOR METAL IRON OBTAINING, METHOD FOR LIQUID STEEL OBTAINING AND DEVICE FOR CHARGING OF THE INITIAL MATERIAL

摘要

The present invention is also directed to a method of producing metallic iron, including forming a deposit layer containing slag produced in the reduction melting process on hearth refractories, thereby protecting the hearth refractories while producing the metallic iron. The present indention is further directed to a device for supplying an auxiliary raw material to a hearth of a moving hearth type reduction melting furnace adapted to produce metallic iron the device including a supply duct vertically connecting with a ceiling portion of the furnace.
