US Patent:

50280368, Jul 2, 1991

Filed:

Mar 14, 1989

Appl. No.:

7/323509

Inventors:

Ajit Y. Sane - Medina OH
Alison W. Gee - Chesterland OH
David J. Eichenmiller - Chesterland OH

Assignee:

The Carborundum Company - Niagara Falls NY

International Classification:

B01D 2901

US Classification:

266227

Abstract:

The filtration of molten ferrous metal is accomplished by providing a porous ceramic filter preferably comprising particles of alumina and partially stabilized zirconia that are spaced by interconnected cells to form circuitous and tortuous pathways throughout the ceramic body. The filter is a disc-like structure that can have different surface configuration such as corrugations or a waffle design. The filter can be flat-surfaced with an array of cylindrical openings or counterbored openings extending completely through the filter, or with openings extending partially into the filter from the upper and lower sides of the filter. Several relatively thin filters can be arranged in tandem, if desired.

US Classification:

2105161

Abstract:

A molten metal filter medium comprised of at least two opposed wedge-shaped plates having at least one hollow generally oblong member comprised of porous ceramic material attached at a first end to one of the plates and at a second end to the second plate, at least one of the plates including a passage to an outlet communicating with the hollow member, wherein molten metal can enter the filter through the hollow member and exit the filter through the passage in the end plate.

Assignee:

Metaullics Systems Co., L.P. - Solon OH

International Classification:

C22B 902

US Classification:

75407

Abstract:

A filter cartridge for a molten metal filtering system is provided with a modular construction in which the filter elements are adapted to be removably mounted to an end plate. The filter elements may be removed separately from the filter and replaced with new filter elements without removing the entire cartridge assembly. According to another aspect of the invention, the filter elements are provided with an elliptical cross-section.
