Abstract: Honeycomb bodies, honeycomb structures and extrusion dies, including a transition structural component. A honeycomb structure (100) includes a plurality of interconnected webs (106) defining a plurality of cell channels (108) in a honeycomb matrix (109) having a central axis (110) orthogonal to its transverse cross-section. Radial webs (116) diverge outwardly from the central axis (110). Radial webs (116) include a first radial web (150) and a second radial web (152). Tangential webs (120) are arranged concentrically with respect to the central axis (110), wherein at least one of the tangential webs (120) is a tangential transition web (142). At least one transition structural component (140) is located radially inward from the tangential transition web (124) and includes a first inclined web (144) having a first end (144A) coupled to the first radial web (150) and a second inclined web (146) having a first end (146A) coupled to the second radial web (152). Extrusion dies configured to make the honeycomb structures are provided, as are other aspects.

Abstract: Systems and methods for efficient microwave drying of extruded honeycomb structures are disclosed. The methods include conveying first and second sets of honeycomb structures in opposite directions through multiple applicator cavities. Each honeycomb structure has a moisture content MC, and the honeycomb structures within each cavity define an average moisture content MCA between 40% and 60% therein. The methods include irradiating the first and second sets of honeycomb structures within the cavities with microwave radiation having an amount of input microwave power PI that results in an amount of reflected microwave power PR from the honeycomb structures, where PR

Abstract: Systems and methods for rapid drying of ceramic greenwares having a high graphite content are disclosed. The methods include employing microwave drying to bring the dryness of the ceramic greenware to a first select dryness and then employing close-coupled hot-air drying to bring the dryness to the final target dryness. The judicious use of close-coupled hot-air drying reduces end defects due to unevenness in the microwave drying process while also substantially speeding up the drying process. Various configurations for and combinations of microwave drying and close-coupled hot-air drying are disclosed.

Abstract: A thin-walled honeycomb body (100) having a plurality of repeating cell structures (110) formed of intersecting porous thick walls (112V, 112H) and thin walls (114V, 114H). Each repeating cell structure (110) is bounded on its periphery by the thick walls (112V, 122H) of a first transverse thickness (Tk) and the thin walls (114V, 114H) have a second transverse thickness (Tt) that subdivides each repeating cell structure (110) into between 7 and 36 individual cells (108). In the thin-walled honeycomb body (100), the first transverse thickness (Tk) of the thick walls (112V, 112H) is less than or equal to 0.127 mm (0.005 inch) and the second transverse thickness (Tt) of the thin walls (114V, 114H) is less than or equal to 0.0635 mm (0.0025 inch), and Tk>Tt. Honeycomb extrusion dies and methods of manufacturing the thin-walled honeycomb body (100) having thick walls (112V, 112H) and thin walls (114V, 114H) are provided.

Abstract: An extrusion system (100) includes at least one sensor (102, 104) to detect localized presence of oil (701) on an exterior surface (715) or skin of wet extrudate material (714 e.g., ceramic material having a honeycomb cross-sectional shape), and at least one infrared emitting device (106, 108) configured to impinge infrared emissions on at least a portion of the exterior surface responsive to one or more sensor signals. Localized impingement of infrared emissions may reduce presence of oil streaks (701) without undue differential drying of the extrudate skin (715), and avoid surface fissures that would otherwise result in fired ceramic bodies. Separately controllable infrared emitters (502), or at least one controllable infrared blocking or redirecting element (603), may be used to impinge infrared emissions on selected areas. A humidification section (120) arranged downstream of infrared emitters (106, 108) may be used to at least partially rehydrate the wet extrudate material, if necessary.

Abstract: Disclosed is a ceramic honeycomb structure comprising a honeycomb body and a multilayered outer layer formed of a thick core layer applied and rapidly dried and a thin clad layer dried more gently to form a crack free dual skin layer. The core layer may have properties that are closer to those of the ceramic honeycomb body in service than the clad layer that may provide a tough outer shell to withstand handling and assembly.

Abstract: Systems and methods for drying skinned ceramic wares (10) using recycled microwave radiation are disclosed. The method includes irradiating wet skinned ceramic wares (10W) in a first applicator section (124W) with microwave radiation (212), wherein said irradiating (212) gives rise to reflected microwave radiation (212R). The method also includes capturing a portion of the reflected microwave radiation (212R) and irradiating a plurality of semi-dry skinned ceramic wares (105) in a second applicator section (124S) with the reflected microwave radiation (212R). Systems for carrying out the method are also disclosed.
