It is thought that displacement of coke oven wall caused by internal gas pressure decreases lateral shrinkage, and effect to coke pushing force. We measured internal gas pressure and displacement of oven wall and pushing force of commercial oven, under different gas pressure of coal blend. Wall displacement caused by internal gas pressure of plastic layer at oven center, but pushing force increased with increase in gas pressure. Decrease in lateral shrinkage of high gas pressure coal blend influenced increasing pushing force.
