To investigate the factors that affect the shrinkage ratio of coke, the shrinkage behavior of coal/semi-coke during carbonization were measured by using novel equipment. Coking coal samples were heated in vessel during softening stage and were observed using a camera during shrinkage stage. It was found that coke with higher bulk density showed a low shrinkage ratio. Image analysis showed that the dense sample had a low rate of shrinkage in the early stages of shrinkage. It was suggested that the pressuring during softening of coal affects the coke shrinkage and the higher the pressure, the smaller the shrinkage ratio.
