摘要： A dielectric drying method for ceramic formed bodies includes drying a plurality of ceramic formed bodies placed side by side in a direction perpendicular to a conveying direction on upper surfaces of drying tables by conveying the ceramic formed bodies between electrodes of an upper electrode and a lower electrode, and applying a high frequency between the electrodes. In the direction perpendicular to the conveying direction of the ceramic formed body, a distance between the electrodes in two end regions between which a central region is interposed is shorter than a distance between the electrodes in the central region.

摘要： A cutting method of a honeycomb formed body is provided. This is a cutting method of a honeycomb formed body in which, while a kneaded material containing a ceramic raw material is extruded to form a honeycomb formed body with a honeycomb shape having partition walls defining and forming a plurality of cells, the extruded honeycomb formed body is cut before drying by a cutting blade vibrated at a frequency of 0.3 kHz or more in a direction perpendicular to a direction in which this honeycomb formed body moves. It is preferably a cutting method of a honeycomb formed body in which the cutting blade is vibrated at a high frequency of 10 kHz or more.
