2021-06-10 10:23:41

The ceramic filter for aluminum foundry is also called the Molten Metal Filter, which is a three-dimensional network of uniform bone structure. AdTech has long focused on the R&D, production and sales of aluminum metal casting materials, mainly serving various domestic and foreign aluminum processing enterprises. The current products include ceramic foam filter plates, aluminum refining fluxes, degassing equipment, aluminum liquid launders, aluminum silicate plugs, filter boxes, aluminum industrial special-shaped parts, etc.

Aluminum foundry ceramic filter is a very economical and effective filter medium, which can effectively filter out non-metallic solid inclusions in aluminum and aluminum alloy melts. The ceramic foam filter adopts foam sponge and high-purity ceramic materials, it has a good open-cell structure and is manufactured under strict quality control. The alumina foam ceramic filter can effectively remove large inclusions and absorb micron-sized particles of inclusions in molten aluminum, which can improve surface quality, improve product performance, improve microstructure, and increase yield. Ceramic foam filters are widely used in the production fields of aluminum profile, aluminum foil, aluminum alloy, and so on.

The ceramic foam filter has a high pore size, high through-hole rate, sufficient sintering, good flexural and compressive strength, ensuring a high-efficiency filtering effect. AdTech has a variety of ceramic foam filter plates with pore sizes ranging from 10 to 60 PPI, with a complete range of sizes. Foam ceramic filter plates are widely used in the filtration and purification of various aluminum and aluminum alloy melts in continuous casting, semi-continuous casting, gravity casting, and low-pressure casting. In addition to general specifications, it can be designed and manufactured according to customer needs.

Foam ceramic filter plate production process: the use of three-dimensional network structure and connected pores of the organic foam sponge as a carrier, invade it into the thixotropic special ceramic slurry, and adopt a special roll extrusion process to make the ceramic slurry evenly applied on the skeleton of the carrier, it is dried and solidified and then fired at a high temperature.
