Abstract

PURPOSE: To obtain formed coke having improved thermal properties as metallugical coke, not causing fusing and deformation, by using caked coal having adjusted particle sizes corresponding to the degree of caking as a raw material.
CONSTITUTION: Raw material of caked coal is powdered into particle sizes of ≤3mm, caked coal having the maximum fluidity (indicated by logddpm) by Giesler plastometer of ≥3 is adjusted to particle sizes of ≤1.5mm, and these coals are blended with non-caked coal, to give the desired formed coke.
EFFECT: Stable coke quality is obtained, and smooth caking operation is made possible.
