As lowering the thermal reserve zone temperature in blast furnace is known to reduce the reducing agent rate and enhance the productivity effectively, this work aim at elucidating influence of pre reduction temperature of iron oxide samples to wustite (FeO) on reduction rate of FeO to Fe by using a thermobalance.
As a result, for samples of sinter, commercial pellet, and iron ore, it was found that decrement of pre reduction temperature led to enhancement of reduction rate of FeO to Fe, giving to a largest extent for iron ore.
These enhancements of reduction rate of FeO to Fe would be mainly because the wustite samples had larger specific surface area for lower pre reduction temperatures.
