Method and apparatus for rapid reduction of iron oxide in a rotary hearth furnace |
摘要 |
A method and apparatus for producing direct reduced iron from dry compacts composed of iron oxide and carbonaceous material by feeding compacts no more than two layers deep onto a hearth and removing all the volatiles and metallizing the compacts by exposing said compacts to a radiant heat source at a temperature of from about 1315 to about 1430 DEG C for a total time period of about four to ten minutes and partially cooling the compacts while discharging them from the hearth. <IMAGE> |
