In recent years, the need for CO2 reduction in blast furnaces has been increasing, and therefore steel companies have been making efforts to reduce reducing agent ratios. In order to realize the reduction of the reducing agent ratio, there is a method of reducing the amount of coke by using coke having higher reactivity than conventional coke. We expect that the addition of flyash to coal enables the production of highly reactive coke with catalytic effect. Therefore, We carbonized coal blended with flyash and measured coke strength, particle size, and reactivity. As a result , it was found that the strength was improved at addition of 3% and that it was possible to maintain the strength as the base at addition of 10%. It was also found that the coke particle size increased and the reactivity improved as the flyash additive rate increased.
