Molten Metal Foam Filter Smelting aluminum alloys presents a number of difficulties. The low density of aluminum alloys contributes to the formation of gas shells and porosity, since gases easily penetrate into the metal medium and saturate it. Aluminum is easily oxidized. It is difficult to clear the melt of slag and oxides. Slag and […]

Zro2 Porous Ceramic Filter Filtration of melts has now become an integral part of the technological process of melting and casting aluminum alloys at all enterprises. Apply mesh, granular and porous ceramic filters. Strainers are made of fiberglass or metal mesh with mesh sizes from 0.5 × 0.5 mm to 1.5 × 1.5 mm. Zro2 […]

Types of filters for various metals 1. Filters for steel If metal is necessary for filtering – this is steel, then filters made on the basis of zirconium oxide are perfect for this purpose. They can be used at a temperature of 1700 degrees Celsius, however, if the application is not long, then it is […]

Alumina Foundry Filter The incorporation of extraneous elements (particles) into the metal can sometimes lead to the unsuitability of the entire batch of products made and this type of metal, which in turn leads to complete rejection. Until recently, such a problem was considered practically unsolvable, and it would seem impossible to solve the issue […]

Zirconia Cff When use Zirconia Cff, inclusions are captured on a filter installed in the metal flow path. Simple filters are fiberglass or steel mesh. They capture oxide films, but not small inclusions. A more efficient filtration is ensured by using ceramic foam filters (PCF), which are a spongy ceramic structure in which molten metal […]

Alumina Foundry Foam Filters Alumina Foundry Foam Filters with a coating for filtering aluminum, silumins, TsAM and other aluminum alloys from slag impurities, oxides, oxide films and gases at a liquid melt temperature up to 900 ° C .. SHORT DESCRIPTION Alumina Foundry Foam Filters are made from aluminum-borosilicate glass of type “E” with different […]
