摘要： Ceramic tubes (10) are manufactured from a mixture that includes ceramic powder. The mixture is extruded through a die (48) to form a tube (10). The tube (10) is passed through an open-ended dryer (16), calciner (20), transition zone (22), sintering furnace (24), and cooler (26). Thereafter, the tube (10) is cut to the desired length (which may be very long). The quality of the tube (10) is enhanced by applying a vacuum to the mixture prior to extrusion. For tubes (10) made of non-oxide ceramics, an inert atmosphere is maintained both inside and outside the tube in all sections of the equipment that operate above 200°C. A controlled tension is applied to the tube (10) by means of first pinch rolls (18) disposed downstream of the dryer (16) and second pinch rolls (30) disposed downstream of the cooler (26).

摘要： The present invention provides for a manufacturing apparatus for forming a ceramic preform from an extrudate having a first end and a second end. A cutter forms the first and second ends of the extrudate complementary to each other such that the first and second ends of the extrudate align with each other in a spaced relationship to define a preform having a substantially uniform exterior surface and a substantially uniform thickness. The present invention provides for a method of forming the preform from the extrudate having the first and second ends utilizing a mandrel. The method includes the step of aligning the second end complementary to the first end of the first layer in a spaced relationship to define the preform having the substantially uniform exterior surface and the substantially uniform thickness.

摘要： 1. In an apparatus for cutting the walls of extruded tubing material to a variable depth as it emerges from an extruder, the combination comprising an extruder diaphragm and die, a mandrel extending outwardly from said die, a cutter body defining an aperture mounted over said die and around said mandrel extending from said die, a plurality of cutter blades adjustably mounted in spaced relation around said mandrel on said body for simultaneous inward movement transverse to the axis of said mandrel and to a position to close tolerance therewith in a single transverse plane, means adapted to move said blades inwardly and means for returning said blades to their initial starting positions. 12. In a method for forming cuts on the exterior surfaces of an extruded ceramic tube, the steps comprising extruding a ceramic tube from an extruder assembly including an extruder diaphragm, die, and extruder mandrel extending exteriorly from said die, rapidly moving a plurality of blades inwardly in simultaneous movement at given intervals in a plane transverse to the direction of extrusion to an adjustable position in close tolerance with the extending end of said mandrel, said blades being initially mounted in spaced relation radially around said extrusion mandrel, said blades being adapted to intercept the surface of said ceramic tube substantially in a single plane transverse to the direction of extrusion, whereby a score completely circumscribing said tube in a single plane is formed, and returning said blades are the conclusion of the inward stroke to its initial position after a swell time coordinated with said extrusion speed, said entire movement and return being adjusted to a period of time rapid enough to form a substantially continuous cut without a notching effect. 16. In the extrusion of moist elongated ceramic members and the subsequent substantial drying of same to rigid brittleness, an improved method for severing the elongated ceramic members into exact lengths and exact dimensional tolerances comprising the steps of forming the moist extrudable ceramic mix rigid enough to hold its shape when extruded yet plastic enough to flow slightly into depressions when extruded, extruding moist, elongated ceramic member from said material, circumferentially scoring the surface of the moist extruded member at at least one station therealong at which severance is desired, effecting said substantial drying of the extruded member, and applying a bending stress upon the dried member at said scored station thereby breaking the member proximate the scored station into separate lengths.
