The reaction rate of solution loss with CO2 gas was measured under the conditions which are corresponding to those in the blast furnace. It is represented by the following equation.
where R=reaction rate
k1, k2, k3=reaction rate constant
PCO, PCO2=Partial pressure of carbon monoxide and carbon dioxide
f (Dp), h (SL) =corrective term
From the results of the experiments and the dissection of blast furnace, a mathematical model of blast furnace was made by presuming the degradation of coke by gasification.
This model is used for discussing what kind of effects the coke properties have on the blast furnace operation.
