    • An electric furnace for heating a metallic material contained in a crucible (120) which is positioned on a base (114). The electric furnace includes a sleeve (100), an electric heating element (106) disposed on the inner surface of the sleeve, a removable lid (112) for covering a top opening of the sleeve (100) and at least one handle (118) disposed on the outer surface of the sleeve (100) to permit the sleeve (100) to be lifted and removed from or placed on the base (114). When the sleeve (100) is placed on the base (114) enclosing the crucible (120), the removable lid (112) is placed on the top opening of the sleeve (100) and an electric current is applied to the electric heating element (106), heat generated by the electric heating element (106) and retained in the furnace melts the material contained in the crucible (120).

    • A process and apparatus for supplying solid feed materials for a direct smelting process to solids injection lances of a direct smelting vessel is disclosed. The feed materials supply apparatus includes a supply line (L) for conveying iron-containing material and solid carbonaceous material under pressure to solids injection lances (7), and the supply line includes a main feeder line section (15) and a plurality of branch line sections (17) extending from the main feeder line section. Each branch line section is connected to one solids injection lance for supplying iron-containing material and carbonaceous material to that lance. The apparatus further includes an assembly for dispensing iron-containing material under pressure into the main feeder line section of the supply line and an assembly for dispensing carbonaceous material under pressure into the main feeder line section of the supply line.
