Abstract

PURPOSE: To prepare metallurgical coke having low permeation index, by carbonizing a mixed coal having balanced cold strength and strength after gasification, in a conventional chamber oven.
CONSTITUTION: Several kinds of raw coal are mixed to get a mixed coal having an inert content of 25W35%, a content of vitrinite having a reflectivity of 1.10W1.50 of ≥35%, and an index obtained by multiplying the ash content and the basicity of ash (B-index) of ≤1.5. The mixed coal is carbonized in a conventional coke oven to obtain high quality metallurgical coke having a cold strength (JIS drum strength DI150 15) of ≥82.5, and the strength after CO2 gasification reaction (CRS) of ≥50.
