Methods of firing ceramic-forming honeycomb bodies are disclosed that include heating the honeycomb bodies and blocking furnace gases from flowing through the honeycomb body by placing a layer selected from the group consisting of a graphite layer, a graphite-containing layer, an activated carbon layer, or an amorphous carbon layer adjacent an endface of the honeycomb body. Heating removes organic pore-forming material and graphite pore-forming material in the honeycomb body. The layer oxidizes to form a porous layer after firing to a first temperature, and furnace gases flow through the honeycomb body.

A die setting apparatus is provided for a ceramic core is provided. The die setting apparatus includes a first setter abuttable with a first side of the ceramic core and a second setter abuttable with a second side of the ceramic core opposite the first side. At least one of the first and second setters includes two or more pieces respectively arranged to form one or more gaps. Each of the one or more gaps is oriented to thermally adjust in correspondence with thermal changes of the ceramic core during a firing process thereof.

A method for producing a ceramic honeycomb structure including: plugging ends of cells on one of a first end face side and a second end face side in each of the cells of a ceramic honeycomb formed body that includes partition walls defining the cells extending from the first end face to the second end face; placing the ceramic honeycomb formed body on a shelf board with the first end face facing downward; arranging at least one lid member on the second end face of the ceramic honeycomb formed body so as to completely cover the second end face; and placing the ceramic honeycomb formed body together with the shelf board and the lid member in a firing furnace and firing the ceramic honeycomb formed body.

A receiving table 100 for supporting a side surface of a honeycomb formed body, the side surface being parallel to a cell extending direction. The receiving table 100 comprises: a body portion 10 having a groove 11 extending in one direction; a support portion 20 comprising: a flexible sheet substrate 21 in contact with a surface of the groove 11 of the body portion 10; and a foam layer 22 attached to the flexible sheet substrate 21, the foam layer 22 being brought into contact with the side surface of the honeycomb formed body; and fixing members 30 for fixing the support portion 20 to the body portion 10. The support portion 20 is provided in a non-adhesive state to the body portion 10.

Disclosed herein is a method and apparatus for automatic extrudate loading and alignment. An extrudate handling system includes a head end assembly and an imaging device (which may be part of the head end assembly). The imaging device is configured to image an end face of an extrudate, and generate, during translation of the extrudate, an imaging output signal indicative of a rotational position of the end face of the extrudate. The head end assembly includes a rotational effector to rotate the extrudate during translation thereof and a fixed effector rotationally fixed relative to a track. The extrudate handling system is able to determine the rotational position of the web angle of the extrudate and precisely adjust the rotational position while linearly translating the extrudate along the track. The extrudate handling system provides greater accuracy, reduced costs, and improved results.

A method for producing a honeycomb structure including producing an unfired pillar shaped honeycomb body; placing the unfired pillar shaped honeycomb body on a receiving table such that the unfired pillar shaped honeycomb body stands thereon; conveying the unfired pillar shaped honeycomb body placed on the receiving table; drying the unfired pillar shaped honeycomb body after the conveying step, or drying the unfired pillar shaped honeycomb body during the conveying to obtain a honeycomb dried body; and firing the honeycomb dried body to obtain a honeycomb structure. The receiving table includes at least one protrusion. In the honeycomb formed body conveying step, the unfired pillar shaped honeycomb body is conveyed while supporting it by inserting the at least one protrusion of the receiving table into a bottom surface of the unfired pillar shaped honeycomb body placed on the receiving table.

The invention relates to a device for storing objects under defined temperature conditions and humidity conditions. In particular, the invention relates to a device for curing objects made of concrete. The device has a shelving system having a plurality of shelf supports and a plurality of bearing elements for supporting shelves supported on the shelf supports and arranged one above the other in a plurality of levels, on which shelves the objects are stored. According to the invention, a flow pipe system for distributing supply air provided in a climate system is at least partially integrated into the shelving system. A plurality of shelf supports in this case are at least in sections at the same time downward pipelines of the flow pipe system that the provided supply air is able to flow through. As a result, condensation at the foot of the shelving system and thus corrosion is counteracted at the shelf supports, thus increasing the service life of the shelving system.

The present disclosure relates generally to methods of manufacturing plasterboards, such as gypsum wallboards. One aspect of the disclosure is a method of manufacturing a building board that includes providing a wet building board by allowing a plaster slurry to set between opposing facings, the wet building board having a set plaster core disposed between the facings; and providing a surfactant (such as a quaternary ammonium salt surfactant) on at least one of the facings (e.g., by applying an aqueous surfactant-containing composition to the facing); then conducting the wet building board to a drying oven, for example, via one or more conveyers (e.g., rollers and/or belts and/or rails); and drying the wet building board in the drying oven to provide the building board.

Methods of firing ceramic honeycomb bodies are disclosed that include heating the ceramic honeycomb bodies and blocking furnace gases from flowing through the ceramic honeycomb body by placing an aluminum metal layer adjacent an endface of the honeycomb body. Heating removes organic pore-forming material and graphite pore-forming material in the ceramic honeycomb body. The aluminum metal layer oxidizes to form a porous Al2O3 layer after firing to a first temperature, and furnace gases flow through the ceramic honeycomb body.

A receiving table 100 for supporting a side surface of a honeycomb formed body, the side surface being parallel to a cell extending direction. The receiving table 100 comprises: a body portion 10 having a groove 11 extending in one direction; a support portion 20 comprising: a flexible sheet substrate 21 in contact with a surface of the groove 11 of the body portion 10; and a foam layer 22 attached to the flexible sheet substrate 21, the foam layer 22 being brought into contact with the side surface of the honeycomb formed body; and fixing members 30 for fixing the support portion 20 to the body portion 10. The support portion 20 is provided in a non-adhesive state to the body portion 10.
