Conditions for Minimizing Direct Reduction in Smelting ...

In a 2 stage-smelting reduction process, it is favorable to lower the reduction degree of iron ore in a pre-reducing unit by lowering its temperature to avoid any troubles due to stickiness of high reduced iron ore. However, less pre-reduced iron ore can induce direct reduction in a melter-gasifier, which can increase coal ratio.
