Abstract: The procedure for the production of honeycomb structure body with a column mold having cells that permeate both end surfaces along its longitudinal direction, comprises producing burning profiles that are placed on workpiece (20) in relation between a position of each vehicle (10), at a temperature at which the workpieces are burned in an oven. The workpieces as formed ceramic bodies having ceramic raw materials are placed on each vehicle that is conveyed into the oven on the basis of the burning profiles that is received in the burning profile positioning step. The procedure for the production of honeycomb structure body with a column mold having cells that permeate both end surfaces along its longitudinal direction, comprises producing burning profiles that are placed on workpiece (20) in relation between a position of each vehicle (10), at a temperature at which the workpieces are burned in an oven. The workpieces as formed ceramic bodies having ceramic raw materials are placed on each vehicle that is conveyed into the oven on the basis of the burning profiles that is received in the burning profile positioning step. The shape of the workpieces is similar to the shape of the honeycomb structure body. The number of the workpieces that are to be placed on the vehicle, is slighter than a given number. Replacement element workpieces (25) are placed on the vehicle so that a physical total size of the workpieces and the replacement element workpieces is same as the physical total size of the workpieces with the given number. The physical size is a quantity of a component of organic materials. The replacement element workpiece that exists out of the same material like the workpiece is used in the burning step. The quantity of the component of organic materials in the replacement element workpiece lies within an area of +- 10% of the component of the organic materials in the workpiece. The height of each replacement element workpiece is similar to the height of each workpiece. The physical size is a caloric value or endothermic value. The burning profile positioning step comprises mounting a measuring unit on each vehicle for measuring maximum caloric power that is subjected on the vehicle conveyed in the oven under a condition, burning the workpieces that are placed on each vehicle in the oven while a temperature in the oven is changed on the basis of burning profiles corresponding to the number of work pieces by the defective workpieces, receiving the caloric power that is increased on each vehicle, by the measuring unit, obtaining a difference between the caloric power and a reference value that corresponds with a caloric reference power that is raised on the vehicle having a given number of workpieces, and determining the burning profile that is raised on all vehicles on the basis of caloric power with minimum difference. The replacement elements are placed on the vehicle by defective workpieces that are removed by the vehicle so that the vehicle has a same weight like the vehicle on which a given number of workpieces is placed. The burning profile positioning step is carried out to produce the honeycomb structure body on the basis of received burning profiles on the basis of caloric power of minimum difference, even if the number of workpiece is changed after a termination.
