Method and apparatus for rapid reduction of iron oxide in rotary hearth heating furnace |
| abstract |
PROBLEM TO BE SOLVED: To provide a method and an apparatus for rapidly and efficiently reducing iron oxide in a rotary hearth heating furnace (RHF). SOLUTION: The compact 32 is supplied at a depth not exceeding 2 layers on the hearth of the RHF 34, and the compact 32 is supplied by a radiant heat source. Exposure to a temperature of 15 to about 1430 ° C. for a first period of about 1 to 3 minutes to remove all volatiles and place in an oxidizing atmosphere where there is sufficient free oxygen to generate from compact 32 While burning most of the flammable gas, producing a combustion gas, and then compressing the compact with a radiant heat source in an atmosphere free of free oxygen by about 131 A second of about 3 to 9 minutes at a temperature of 5 to about 1430 ° C. Exposing for a period of time to allow the gas and the compact 32 to flow co-currently during the first period and countercurrently during the second period; Forming and discharging. |
