Abstract

PURPOSE: To obtain briquetted coke of good quality having improved wear resistance, by high-temperature carbonization of a molded coal prepared from a mixture of a finely pulverized collected and precipitated coke of low value produced from a coke plant with a raw material for the molded coal.
CONSTITUTION: Finely pulverized collected and precipitated coke of low value produced from a coke plant is mixed with a raw material, e.g. low-rank, caking, coal- type tar, pitch, modified coal, and petroleum asphalt, hot kneaded and press molded. The molded coal thus obtained is fed to a shaft furnace, whose atmosphere is kept at 300W500°C, and heated rapidly to harden the surface, and further carbonized by heating at a heating rate of 10W50°C/min at 200°C, 0W20°C 1min at 600°C, and a maximum rate of 30°C/min at 600W1000°C.
