| description | A method and apparatus are 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 may also be wedge shaped. A cross section of the filter is shown in figure 7A. The filter screen of the present invention may have a wear resistant boride, nitride, or nickel-based coating at the surface of the screen.
L'invention concerne un procédé de production d'un substrat céramique en nid d'abeille à parois minces, consistant à extruder une matière de fournée céramique plastifiée à travers un tamis pourvu de fils filtrants en coin, destinés à retirer les particules étrangères et la matière de fournée agglomérée. Ces fils filtrants sont supportés par un ensemble de fils de support, fixés de façon sensiblement perpendiculaire aux fils filtrants. Ces fils de support peuvent aussi être avantageusement agencés en coin. Le tamis de la présente invention peut présenter à sa surface une couche résistante à l'usure, généralement une couche de borure ou de nitrure. Ce revêtement résistant à l'usure peut être également un revêtement à base de nickel. |
