Method for producing a disc roll, disc roll and disc member base material

摘要

The present invention relates to a disc roll (10) comprising a plurality of disc members (12) each containing a crystalline cordierite or each being capable of generating a crystalline cordierite upon conveyance of a high-temperature article therewith. Each disc member also contains an inorganic fiber like ceramic or silica fiber and optionally a binder. Also disclosed are methods for producing the disc roll and disc member base materials for obtaining the disc members. A method for producing a disc member base material comprises subjecting a slurry raw material to a paper-making process.
