PROBLEM TO BE SOLVED: To provide a process for operating coke ovens which enables an increased coke production without damaging furnace wall bricks. SOLUTION: A database comprising operation data, blend coal data, coke data, repair data and damage data produced for each carbonization chamber is analyzed to construct an extrusion force-generation model wherein the extrusion force generated in each carbonization chamber under a certain condition is mathematized. The operation condition for each carbonization chamber is set based on this extrusion force-generation model. If the current extrusion force is smaller than that damaging the furnace wall bricks, the amount of coals charged in the oven will be increased under the extrusion force-generation model until the extrusion force which has been recalculated using the extrusion force-generation model approximates the extrusion force damaging the furnace wall bricks. By reflecting the amount of coals charged under the extrusion force-generation model in the amount of coals charged in the actual oven, the coke production may be increased without damaging the furnace wall bricks.
