The dependence of the mechanical strength of coke on its granulometric composition is determined for the coke shop at PAO NLMK. The smaller fractions produced from the >80 mm fraction on crushing conform to a normal (Gaussian) distribution. Under the same mechanical load, larger coke pieces are less likely to retain their initial size and more likely to disintegrate. The 40–60 mm class most improves the mechanical strength of blast-furnace coke. With increase in content of this class, the coke will be stronger. [ABSTRACT FROM AUTHOR] |
