Abstract

PURPOSE: To produce coke from coal and briquettes, by carbonizing caking coal mixed with briquettes composed mainly of non-caking coal and giving coke having specific shrinkage, crushing strength and particle size, thereby enabling the use of a wide variety of non-caking coal, and increasing the amount of the non-caking coal.
CONSTITUTION: One or more kinds of non-caking coal are compounded to give a mixed coal for carbonization having a carbonization shrinkage of 5W15% and a crushing strength of ≥100 kg/cm2 after carbonization. The mixed coal is added with a binder, pulverized, heated, kneaded, and formed to briquettes having diameter of 5W20 mm by a briquetting machine using a mold having a cavity of, e.g. 20×20×15mm, 10×10×6mm, etc. The briquettes thus obtained are mixed with caking coal, and carbonized in a chamber oven to obtain the objective coke. When the crushing strength of the coke prepared from the briquette is lower than 100 kg/cm2, the strength of the final product becomes undesirably low; and when the carbonization shrinkage is larger than 15%, or the particle diameter is larger than 20mm, the coke strengh is lowered because of the generation of cracks between the briquette and the caking coal.
