摘要

A new smelting reduction process with a coke packed bed has been developed from iron, chromium, and nickel recovery from BOF dust, and for siumltanueus recovery of zinc and iron from the electric arc furnace dust. The process is characterized by direct use of fine raw materials without agglomeration, recovery of almost the whole amount of zinc and lead, and no emission of secondary waste, compared with the conventional recovery methods. The commercial plant for BOF dust recycling has been operating stable with a metal production capacity of 200 tons per day. The blast condition is controlled so that the temperature at the lower tuyere level becomes higher than 1550 deg C, which is the condition required for the smelting reduction of chromium and iron oxides.
