DEVICE AND METHOD FOR REDUCTION PROCESSING FOR PRODUCING OF METALLIC IRON

摘要

At least one member selected from among ASR, household electrical appliance shredder dust, waste plastic, waste-derived RDF, RPF, polluted sludge, oily sludge, waste wood, waste fiber, waste rubber and animal or plant residue as a waste matter being effective as a reducing material and functioning as a heating material through generation of an amount of heat needed for reduction is fed into a reducing furnace (2) supplied with zinciferous iron oxide or zinc oxide or iron oxide. Reduction treatment is carried out using the above member as a heat source without the use of any auxiliary fuel. Thus, zinc reduction and/or iron oxide reduction allowing production of metallic iron can be attained while realizing processing cost saving (running cost saving attributed to nonuse of auxiliary fuel).
