A method for manufacturing a metal-impregnated ceramic fired body includes: a step 1 of contacting a ceramic formed body with a metal in a form of granules, a step 2 of heating the metal at or above a melting point thereof in a state where the metal in the form of granules is in contact with the ceramic formed body so that the ceramic formed body is fired while the metal is impregnated into the ceramic formed body, thereby obtaining a metal-impregnated ceramic fired body.

Method for manufacturing metal-impregnated ceramic fired body

Provided is a method of manufacturing a honeycomb structure capable of manufacturing a honeycomb structure excellent in external dimension accuracy. A method of manufacturing a honeycomb structure includes: a preparation step of preparing a honeycomb molded body; a storage step of storing the honeycomb molded body under a state in which temperature and humidity are adjusted; and a fitting step of inserting the honeycomb molded body after the completion of the storage step into a heated metal tube and then cooling the metal tube.

Method of manufacturing honeycomb structure and honeycomb structure

A heat exchange member including: a honeycomb structure body including: partition walls extending from a first end surface to a second end surface to define cells forming flow passages for a first fluid; and an outer peripheral wall; and a covering member configured to cover the outer peripheral wall of the honeycomb structure body. The partition walls and the outer peripheral wall contain ceramic as a main component, and the outer peripheral wall surface has a peak count RPc according to JIS B 0601:2013 set to 55 pks/cm or larger.

Heat exchange member, heat exchanger using heat exchange member, and method of manufacturing heat exchange member

A method for producing a shrink-fitted member by arranging a pillar shaped ceramic body inside a deep-drawn stainless steel pipe and shrink-fitting them. The method includes: a preparing step of preparing the deep-drawn stainless steel pipe produced by deep-drawing and the pillar shaped ceramic body; a heating step of heating the deep-drawn stainless steel pipe to 900° C. or more; and a shrink-fitting step of inserting the pillar shaped ceramic body into the heated deep-drawn stainless steel pipe and shrink-fitting them.

Method for producing shrink-fitted member

A method for producing a shrink-fitted member by arranging a hollow type pillar shaped ceramic body inside a metal pipe and shrink-fitting them, the hollow type pillar shaped ceramic body including: an outer peripheral surface and an inner peripheral surface in a direction substantially parallel to an axial direction; and a first end face and a second end face in a direction substantially perpendicular to the axial direction. The method includes arranging the hollow type pillar shaped ceramic body inside the metal pipe while gripping the hollow type pillar shaped ceramic body using a chuck mechanism.

Method and device for producing shrink-fitted member

A method for drying at least one unfired columnar honeycomb formed body comprising a raw material composition containing at least one raw material of ceramics, water and at least one heat-gelling binder, and cells defined by partition walls comprising flow paths from a first end surface to a second end surface. The method comprising drying the honeycomb formed body by passing hot gas satisfying 0.8&#x2264;T/T&#x2264;3.3, where Trepresents a gelation temperature of the binder (&#xb0; C.) and Trepresents a wet-bulb temperature of the hot gas (&#xb0; C.) through the flow paths from the first end surface and out the second end surface, while surrounding the honeycomb formed body with a correction mold to correct the shape of the honeycomb formed body during drying.
