Abstract
PURPOSE: To obtain metallurgical coke from pulverized coal having a very poor caking property, by dry distillation of a mixed coal whose Gieseler fluidity is adjusted by adding a bituminous substance to the pulverized coal.
CONSTITUTION: A mixed coal whose volatile content and Gieseler fluidity are adjusted to 23W40% d and M.F. 30W200 D.D.P. M. respectively by adding 5W 30 wt.% of a bituminous substance to pulverized coal is mixed an/or kneaded, and dry distilled. If the amount of the bituminous substance is < 5 wt.%, the densifying of coal by the substance in the carbonizatin chamber cannot be produced. If the amount is > 30 wt.% the formed coke is porous and has a low strength. If the gieseler fluidity of the mixed coal is < 30 D. D, P. M., the bonding between coal particles is weak, and strong network cannot be formed. If the fluidity is >200 D.D. P.M., the swelling pressure in coking shuild be suppressed.
