ABSTRACT
Cold strength indices М25(40) and М10 determine gas permeability of burden layer in the blast furnace to zone of liquid-plastic state and coke windows in this zone. CRI and CSR indices determine mechanical strength of coke in the lower part of furnace stack, in the zone of liquid-plastic state and below it including furnace hearth. It is incorrect to contrast them or diminish the importance of each index for blast-furnace smelting.
