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.

Abstract: 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.
Abstract translation: 公开的挤出蜂窝体的设备和方法提供了挤压蜂窝结构的弯曲的校正，采用了一种偏转器装置，其具有基板，该基板包括在平行于挤出轴线的方向上对齐的开口，塑料材料通过该开口被输送到模具。 偏转器装置包括可移动地安装到基板的下游侧或上游侧的弓形板。 弓板包括恒定面积孔径。 位于挤出模头上游的偏转器装置通过在开口上的恒定面积孔的位置赋予一定程度的弓形减小，从而在进入模具的流动流上赋予压降梯度。
