摘要：
The expediency of using various amounts of nut coke in blast-furnace smelting is evaluated in relation to the quality of the skip coke. Data from blast-furnace operation are analyzed to obtain relations expressing the dependence of the consumption of nut coke on the unit consumption of skip coke and its abradability index M10. A blast furnace can run smoothly with the use of nut coke if its concentration in the charge does not exceed 20 kg/ton pig iron and the abradability index of the skip coke is satisfactory (M10 ≤ 9.0%). The average value of the coke-substitution equivalent was determined to be 0.67 kg/kg nut coke.
