Abstract
The mathematical model which describes the behavior of ferrocoke in blast furnace was developed and incorporated into the mathematical blast furnace model. The effect of ferrocoke on the reduction of reducing agent rate and carbon rate of blast furnace was investigated with the mathematical blast furnace model.The effect of ferrocoke on the reduction of reducing agent rate and carbon rate depends on the ore/coke distribution of burden and operational conditions of blast furnace. High reducible sinter is required for the reduction of reducing agent rate of blast furnace by charging a large quantity of ferrocoke into blast furnaces. The gasification degree of ferrocoke calculated by the mathematical blast furnace model agreed well with the experimental results.
