Abstrakt: The influence of coke quality on its replacement by coke nuts is investigated. Analysis shows that, for coke of higher quality, a greater proportion may be replaced by coke nuts. When coke nuts fines are mixed with ore, the porosity of the batch is not impaired; on charging by means of a separate skip, by contrast, the porosity may be reduced by 5.7—7.6%. Hence, forcing of the furnace process is possible. [ABSTRACT FROM AUTHOR]
