Patent ID: 10279559

Abstract:
The method includes: a formed body forming step of forming each of a plurality of honeycomb-segment formed bodies by extrusion; an aggregate formation step of forming a honeycomb-segment aggregate by applying a fluid bonding material to side faces of the honeycomb-segment formed bodies, and arranging the honeycomb-segment formed bodies so that the side faces are brought into contact with each other; an aggregate shaping step of shaping the honeycomb-segment aggregate by performing a press treatment to the side faces of the honeycomb-segment aggregate; and a drying/firing step of drying and firing the honeycomb-segment aggregate, wherein the aggregate shaping step are performed while keeping the water amount of each of the honeycomb-segment formed bodies to be 30 mass % or more, each of the honeycomb segments has cell density that is 620 cells/cm2 or more, and the press treatment is performed with a contact pressure of 0.005 kg/cm2 or more.
