MANUFACTURING METHOD OF HONEYCOMB STRUCTURE AND HONEYCOMB FORMED BODY

摘要

A manufacturing method of a honeycomb structure includes a forming step of forming a honeycomb formed body having partition walls defining a plurality of cells, a convex wall portion forming step of forming a convex wall portion in the obtained honeycomb formed body, a mounting step of directing downward one end face on which the convex wall portion is formed and mounting the honeycomb formed body on a shelf plate, a firing step of firing the honeycomb formed body mounted on the shelf plate, to form a honeycomb fired body, and a circumference grinding step of grinding a circumferential surface of the honeycomb fired body, to remove the convex wall portion.

1. A manufacturing method of a honeycomb structure comprising:
a forming step of forming a forming raw material, and extruding, cutting and drying the material to form a honeycomb formed body having partition walls defining a plurality of cells which extend from one end face to the other end face and which become through channels for a fluid; a convex wall portion forming step of forming a convex wall portion projected from the vicinity of a circumferential edge of the one end face of the honeycomb formed body obtained by the forming step along a central axis direction of the honeycomb formed body, and processing the one end face so that its cross section has a concave shape; a mounting step of directing downward the side of the one end face on which the convex wall portion is formed, and mounting the honeycomb formed body on a shelf plate so that the convex wall portion abuts on a shelf plate surface; a firing step of firing the honeycomb formed body mounted on the shelf plate, to form a honeycomb fired body; and a circumference grinding step of grinding a circumferential surface of the honeycomb fired body obtained by the firing step, to remove the convex wall portion.
