A mathematical model for the simulation of Si transfer process in the blast furnace was developed. The whole regions of the furnace from the stock level to the hearth were one-dimensionally simplified, and mass and heat transport and main reaction rates in each region were included in the simulation. The feature of the model is that instead of the slag-metal reaction in the hearth the reaction between SiO-gas and iron-droplets in the dropping zone is exclusively taken into account as the Si transfer reaction. When the temperature distribution is so simulated as to be well coincide with the actual in-furnace distribution, the calculated Si contents in hot metal are proved to be in good agreement with the observed values.
