Abstract

On the basis of a mathematical model, a linear relation is established between the coke characteristics determined in drum tests. Specifically, the relation between the abradability M10 and crushability M25 is as follows: M10 = 100 – KM25. Analytical methods show that K = 1.00–1.11. As an example, applications of the model are presented, and K is calculated for Russian and Spanish data. The basic model may also be applied to other measures of coke’s mechanical strength, as illustrated for the example of the Irsid indices I10 and I20. Ordinary regression in the analysis of statistical data for M25 and M10 proves less informative than the use of the relationship M10 = 100 – KM25. An approach is suggested for finding the physical basis of the linear relation between M10 and M25.
