, in a rotary hearth furnace. The reaction model of carbon iron ore composite can be used simulating blast furnaces only if the models are simple. The heating rate and the reaction rate in a blast furnace are slower than that of a rotary hearth furnace. Therefore, the temperature distribution in the composite can be considered to be uniform, and
