Aluminum Cast Ceramic Foam Filter

Aluminum Cast Ceramic Foam Filter

The aluminum cast ceramic foam filter adopts a three-dimensional network structure and is connected to the pores of the organic foam as a carrier. It invades the thixotropic alumina slurry. The four-corner correction center distance automatic extrusion technology is used. The slurry applies it evenly to the carrier The foam skeleton is baked and cured at a high temperature of 1180°C.

The aluminum cast ceramic foam filter is installed in the filter box to filter the aluminum alloy liquid impurities, so as to meet the needs of aluminum alloy precision casting for the production of high value-added, high-tech performance aviation and transportation. Such as: computer hard drives, printed PS bases, materials that can be made, fan blades of jet turbine engines and other products.

The basic structure of the ceramic filter plate: The ceramic filter plate is composed of a plate base, a positioning seat, an air outlet and a surface film.

The ceramic filter plate is one of the core components of the ceramic filter. It is a new type of porous functional ceramic material, which is covered with crisscross capillary pores (about 1 to 10 microns in diameter). This is the channel for filtration. This component is called the board base layer. The composition of the ceramic filter plate is alumina, silicon carbide and other materials. The main components of the ceramic filter plate outlet and the positioning base are composed of stainless steel or polymer materials.

Advantages of Ceramic Foam Filter

  1. Adopting the principle of adsorption, which can effectively remove large inclusions in molten aluminum and effectively adsorb small inclusions;
  2. No slag drop, effectively reducing the pollution of molten aluminum;
  3. Good thermal shock resistance and improved resistance to molten metal corrosion;
  4. Automated assembly line production, three calibration procedures, accurate size, more in line with the filter box;
  5. Improve surface quality, improve product performance, and improve microstructure.

Alumina ceramic foam filter can effectively remove a large amount of impurities in molten aluminum and adsorb micron-level fine particles, thereby improving surface quality, improving product performance, improving microstructure and increasing output. It is widely used in aluminum, aluminum foil, aluminum alloy and other production fields.

In the process of transportation and use of ceramic foam filter, the filter plates must withstand a certain pressure impact from the outside, so this indicator is also introduced in the standard to measure the quality of the filter plates. The higher the compressive strength, the more durable the product and the better the quality, and vice versa.
