Abstract
A process for producing pig iron in electric furnaces, characterized by heating a charge containing iron oxide and carbonaceous reducing agent in a stream of practically oxygen-free combustion gases in one or more tanks placed outside the melting furnace and, upon heating said furnace charging at 600 to 900º C, preferably at 800º C, transferring the hot charge to the electric furnace without intentional cooling, thereby creating conditions for indirect reduction and high carbon dioxide content in the melting furnace gas itself .
