Abstract

PURPOSE: To obtain a crack-free high density carbon molding by a simple method by mixing a substance having an oxidation temp below that of raw coke into calcined coke and using the mixture as packing coke in calcination.
CONSTITUTION: When raw coke is pulverized, molded, and calcined to manufacture a high density carbon molding, a substance having an oxidation temp. below that of raw coke or a mixture of the substance and calcined coke is used as packing coke in the calcination. The above-mentioned substance includes raw coke, paper, pulp chips, wood chips, grain, charcoal, carbon black and high molecular compounds. The amount of the substance mixed into the calcined coke is required to be ≥about 5wt% to the total amount of the packing coke. In case the amount is <about 5wt% a sufficient crack preventing effect is not obtd.
