Rational Coke Preparation for Blast Furnaces

The relation between the CSR and CRI values of coke and its familiar characteristics is analyzed. The strength and reactivity of coke differ over the blast-furnace height. The economic importance of each of these properties may only be established for specified blast-furnace conditions and technology. The systems for coke stabilization must be selected on the basis of the specific properties of the coke. There can never be a general solution. The optimal stability must be determined for each coke-furnace combination. Literature sources that address the following issues are identified: the equipment for improving coke properties; the necessary processes and their regulation; and the method for determining optimal blast-furnace conditions on the basis of the characteristics of the specific coke-furnace system.
