BLAST FURNACE COKE PRODUCTION

摘要

BLAST FURNACE COKE PRODUCTION A method of producing blast furnace coke of improved hardness and stability includes compacting a finely divided coking coal of which at least 60% by weight has a particle size of less than 1/8 inch (3.2 mm) to form a coal compact of which at least 20% by weight has a particle size of less than 1/4 inch (6.4 mm), breaking the compact to increase the percentage of particles having a particle size below 1/4 inch (6.4 mm) and carbonizing the broken compact to thereby produce blast furnace coke having a minimum hardness of about 68 and a minimum stability of about 55.
