Abstract
Direct reduced iron (DRI), with its sponge-like structure, is chemically reactive and easily oxidized. The author has developed an efficient process for the treatment of DRI, known as the Waxing Process, which makes the DRI resistant to both oxidation and corrosion. According to this process, DRI from the last stage of reduction is transferred into a bath of melted paraffin held at a temperature of 110-120°C and kept for 3-5 sec in it. To check the efficiency of the Waxing Process as inhibitor for reoxidation and corrosion of DRI, several tests are carried out and the results are shown.
