摘要： A method of making ceramic bodies includes systematically orienting the bodies during firing relative to a temperature gradient in a kiln. The systematic orientation of the bodies relative to the temperature gradient can allow for an average deviation of a measured shape of the ceramic bodies from a predetermined target contour shape to be less than what they would be if the bodies were oriented randomly relative to the temperature gradient.

摘要： Systems and methods for real-time, closed-loop shape control of extruded ceramic honeycomb structures are disclosed. Methods include extruding batch material through an extruder barrel and through an extruder die using at least one extrusion screw to form the extrudate, and measuring a shape of the extrudate immediately adjacent the die. The batch material water content is determined or measured, at least one of the extruder barrel and screw temperature are measured, and the extrusion screw rotation rate are measured. At least one of the batch material water content, barrel temperature, screw temperature and rotation rate is adjusted to maintain the extrudate shape to within a select tolerance.

摘要： Microwave drying of ceramic honeycomb logs using a customizable cover that can take the form of a flexible wrap or a rigid cover is disclosed. The cover can be in the form of a wrap disposed directly in contact with the leading edge of the log surface. The cover can also be a rigid cover disposed adjacent but not in contact with the leading edge of the log surface. At least a portion of the trailing edge of the log can remain uncovered either by having windows in the wrap or by the rigid cover only covering the leading edge of the log surface. The customizable cover can be configured to compensate for log shape deformities as well as or in addition to the adverse effect on log shape cause by the drying differential created by passing a log through a microwave drying station leading-edge first.

摘要： Disclosed apparatus and method to extrude a honeycomb, providing correction in bowing of the extruded honeycomb structure, employs a deflector device having a base plate including an opening aligned in a direction parallel to the extrusion axis through which the plastic material is conveyed to the die. The deflector device includes a bow plate movably mounted to the downstream or upstream side of the base plate. The bow plate includes a constant area aperture. The deflector device positioned upstream of extrusion die imparts a degree of bow reduction by the position of the constant area aperture over the opening imparting a pressure drop gradient on the flow stream entering the die.

摘要： Methods of extruding a honeycomb body with an extruder comprise the step of feeding batch material to the extruder, wherein the batch material comprises a ceramic or ceramic-forming material. The methods further include the step of rotating at least one mixing screw to cause the batch material to travel along a flow path defined by a barrel of the extruder. The methods further include the step of indexing a carriage to remove a first device from the flow path and introduce a second device into the flow path of the batch material. In one example, the pressure of the batch material changes less than about 25% as a result of indexing the carriage. In addition or alternatively, further methods include the step of reducing a decrease in temperature of the batch material resulting from the step of indexing. In further examples, the method includes the step of pre-filling a second honeycomb extrusion die held by the carriage with a plugging material.

摘要： An extrusion die is processed to alter the flow of extrudable material through the die by collecting data reflecting flow variations across the face of the die, constructing a graded resistance flow restrictor utilizing the data, and forcing an abrasive machining medium through the flow restrictor and die with the flow restrictor being arranged to deliver higher abrasive flow through die portions initially exhibiting low extrusion rates, the resulting die being useful for the manufacture of ceramic honeycomb bodies exhibiting a reduced incidence of shape defects attributable to die flow variations.

The set of central slots extends from the outlet end to the interior interface portion of the die body. The set of outermost peripheral slots is disposed radially outwardly of the central slots. The interior interface portion of the die body is configured to allow flow of the batch material from the first set of feedholes to the central slots and to the outermost peripheral slots.
