Decreasing pushing force is one of the most important issues for extend coke oven life and stably operating at old coke oven. Especially, pushing force depends on clearance due to lateral shrinkage during carbonization in coke oven. In this study, quantifying lateral shrinkage of coke cake which is made of test coke oven is proposed by using photo-Images processing. It showed there is a high correlational between shrinkage factor (ER;ASTM) and lateral shrinkage rate. In addition, low temperature of coke decreases horizontal shrinkage rate, so narrow lateral shrinkage increases pushing forece.
