METHOD AND APPARATUS FOR EXTRUDING A CERAMIC MATERIAL |
摘要 |
A method is provided for manufacturing a thin-walled honeycomb ceramic substrate by extruding a plasticized ceramic batch material through a filter screen having wedge shaped filter wires to remove foreign particulate and agglomerated batch material. The filter wires are supported by a set of support wires attached substantially perpendicular to the filter wires. The support wires are may also be advantageously wedge shaped. The filter screen of the present invention may have a wear resistant layer at the surface of the screen, typically a boride or a nitride. The wear resistant coating may also be a nickel-based coating. |
