METHOD FOR MANUFACTURING CERAMIC HONEYCOMB FIRED BODY
Document Type and Number:
WIPO Patent Application WO/2011/145445
Kind Code:
A1
Abstract:
A method for manufacturing a ceramic honeycomb fired body is provided with a step for placing a green molded body (1) on a firing base (5), and also with a step for firing the firing base (5) and the green molded body (1). The firing base (5) and the green molded body (1) are respectively column bodies each containing a ceramic material and each having partition walls for forming flow paths. When viewed in the direction in which the flow paths extend, the end surface of the partition walls (3) of the green molded body and the end surface of the partition walls of the firing base have the same pattern. In the placement step, the green molded body (1) is placed on the firing base (5) either in such a manner that the green molded body (1) is shifted a predetermined distance in the horizontal direction from a reference position so that only a portion of the lower end surface of the partition walls (3) of the green molded body (1) is in contact with the upper end surface of the partition walls (3) of the firing base (5), the reference position being the position of the green molded body (1) at which the entire lower end surface of the partition walls (3) of the green molded body (1) is in contact with the upper end surface of the partition walls (3) of the firing base (5), or in such a manner that the green molded body (1) is rotated a predetermined angle (θ) about the vertical axis (V) thereof.
