PROBLEM TO BE SOLVED: To provide a lubricant for oven floor of a coke oven carbonization chamber which can be simply spread on the oven floor of a coke oven carbonization chamber and, can largely reduce the load of an extruder when coke is extruded from the carbonization chamber and discharged after the completion of carbonization. SOLUTION: The lubricant to be spread on the oven floor of a coke oven carbonization chamber before charging coal thereto, has a pyrometric cone equivalent of SK12 or higher, comprises globular bodies made of ceramic, primarily having particle sizes of 1 to 15 mm and desirably has an inclination angle, at which the lubricant having been in the stationary state starts to move, of 10° or less.
