Title:
MUFFLE STRUCTURE FOR CYLINDRICAL FURNACE MADE OF CARBON/CARBON COMPOSITE MATERIAL USING POLYGONAL ANNULAR MEMBER
Document Type and Number:
Japanese Patent JP2023167565
Kind Code:
A
Abstract:
To provide a muffle structure for cylindrical furnace (including vertical cylindrical furnace and horizontal cylindrical furnace), superior in durability, small in heat capacity, not requiring a large-scale manufacturing facility, and capable of considerably reducing operation cost, especially a muffle structure enhancing annular rigidity (rigidity indicating difficulty in deforming in a radial direction) of a structure body (substantially cylindrical polygonal columnar body).SOLUTION: A muffle structure for cylindrical furnace consisting of a polygonal columnar body having a substantially cylindrical shape is devised by mechanically combining plural carbon/carbon composite materials formed in a plate shape being a most simple basic configuration, the materials being high in heat resistance, strength and rigidity and rich in toughness, and plural annular or partially annular carbon/carbon composite materials.SELECTED DRAWING: Figure 1
