Abstract
Coke is produced by heating upto 1,000℃ for 20 hours. So heating program and dry quenching (CDQ) systems are introduced to reduce heating time. The thermal properties and heat transfer mechanism are clarified for the rational operation. This paper describes situations of measurements of the thermal conductivity during carbonization process, numerical analysis of fissure formation in the coke lump, development of thermal pyrolysis, heat transfer mechanism of CDQ and raceway of blast furnace.
