Abstract

PURPOSE: To obtain the title coke having high strength and quality without using an expensive binder, by carbonizing non-caking coal having high volatility slowly into char having specific characteristics usable as a raw material.
CONSTITUTION: Non-caking coal having high votatility is pulverized, preheated at a temperature preferably not more than 600°C, and carbonized under such a mild condition as to leave a volatile constituent. A char thus obtained having an AP inxe (drum index) not less than 20 and a volatile matter (a dry ash free base) of 20% and a Hardgrove-grindability index not more than 60. The char is used as a raw material for molded coke (or its part) and carbonized to give the desired coke.
