Embodiment Construction

[0045] Embodiments of the present invention will now be described in detail with reference to examples shown in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0046] The claims set forth below are incorporated into and constitute a part of this Detailed Description.

[0047] Any reference cited herein is incorporated by reference in its entirety.

[0048] In the following description, the word "cover" is used to describe wraps and rigid covers or shields generally. Accordingly, a cover is sometimes referred to as a wrap and sometimes as a rigid cover, depending on the example embodiment of the cover in question.

[0049] figure 1 is a perspective view of an idealized ceramic extrudate 10 cut into segments or billets 20, also known as pottery blanks. Log 20 has opposing ends 21 and an axial length L1 which may be, for example, about 3 feet, and may have substantially any rea...

Abstract

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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority benefit under 35 U.S.C. §120 to U.S. Patent Application Serial No. 13 / 482,367, filed May 29, 2012, the contents upon which this application is relied upon are incorporated herein by reference. technical field [0003] The present invention relates generally to extruded ceramic honeycomb segments, and in particular to microwave drying of extruded ceramic honeycomb segments using customizable covers. Background technique [0004] The process of forming a ceramic honeycomb structure involves forming an extrudate having a selected or desired shape. The extrudate was wet and referred to as the "leg". Once extruded, it is difficult to controllably change the shape of the log. However, there will be a difference between the desired extrudate shape and the actual extrudate shape. This difference can cause the log to not meet its shape specification, which requires the log to be discarded. T...
