Sintered ore manufacturing method for improving recovery rate of sintered ore

摘要

The present invention not only improves the recovery rate of sintered ore when manufacturing sintered ore using low iron oxides such as mill scale and metal waste generated in various metal processing processes such as steelmaking and cutting such as rolling and wire rod as iron ore sintering raw materials. The present invention relates to a method for producing a sintered ore such that the oil, which is often buried in these lower iron oxides, hardly adversely affects the sintering dust collector.;Low iron oxides such as Fe, FeO, Fe ₃ O ₄ or lower iron oxides such as mill scale, steel sludge, and metal iron that occur in industrial processes such as iron and metal processing, with their respective minerals mixed. When used as a sintering raw material, these low iron oxides are separately mixed with silica, which is usually added as a sintering raw material, and then charged into the upper part of the sintered raw material layer and sintered to improve the strength and the yield of the sintered ore at the upper part of the sintered layer. It is.
