Establishment of a standard for the evaluation of the properties of metallurgical coke is regarded as so difficult that in no country such standard is yet firmly established. For the purpose of helping the establishment of the standard, we have studied the relationship among various property of coke and tried to generalize the properties, using past data.
As a result, the following basic concept was obtained, when the size and sulphur content of coke regarded as independent factors, for the evaluation of the other properties of coke:
Vc=f(S, M)/f(A)
Vc: index for the evaluation of coke properties
S: strength of coke (D15015 index)
M: micro strength index
A: ash content
It is concluded that studies that would take much more time are required for the determination of actual Vc, however, for the purpose of evaluating coke properties, adoption of micro-strength, in addition to strength and ash, would serve our purpose.
