Latvia Alumina Ceramic Foam Filter
-
Latvia alumina ceramic foam Filter is used in the aluminum metallurgy industry and foundries to remove non-metallic inclusions and metal melt in the oxide film.
Before use, it is important to preheat the filter and filter box.
During the preheating process, care must be taken to control the heating rate and temperature distribution. This can minimize the thermal shock and stress in the refractory material of the filter and filter box.
Characteristics of alumina ceramic foam filter plate
1. Excellent dimensional tolerance
2. Stable chemical composition
3. The highest filtration efficiency
4. Excellent strength
5. Resistance to corrosion of molten aluminum and alloys
6. Bevel and compressible gasket
Latvia China Foundry Filter is used in the production of aluminum alloys, aluminum foils, aluminum profiles and other production fields. It can effectively remove large inclusions in aluminum liquid, and adsorb micro-sized particles of fine inclusions, purify the hydrogen content in the aluminum liquid, and reduce the oxidation of hydrogen atom adsorption. Inclusions can improve the surface quality, improve product performance, change the microstructure, and increase the yield. The aluminum melt is filtered and purified.

When Ceramic Filter filters molten aluminum, the molten aluminum flows through the tortuous holes of the ceramic filter plate, and the non-metallic impurities and oxide film (commonly known as slag) in the molten aluminum are affected by the axial pressure, friction, and surface adsorption of the molten aluminum. The combined effect of the slag is retained in the inner surface of the hole and the crevice cavity of the ceramic filter plate, thereby separating the slag and the molten aluminum.
After a period of filtering, the slag remaining on the ceramic filter plate also participates in the adsorption of the slag, which can play a filtering role.
Since the performance of the slag adsorbed on the ceramic filter plate is exactly the same as that of the slag to be adsorbed in the molten aluminum, the surface area ratio is much larger than that of the ceramic filter plate, and the surface activity is also much greater than that of the ceramic filter plate.
Therefore, the ability to adsorb and trap the slag in the molten aluminum is far greater than that of the ceramic filter plate. Because of this, the ceramic filter plate can filter out the fine slag that is many times smaller than its own hole.
Latvia is located in the western part of the Eastern European Plain, on the east coast of the Baltic Sea, and the Gulf of Riga goes deep inland; it borders Estonia, Russia, Belarus and Lithuania. The area is 64,589 square kilometers, of which the land area is 62,046 square kilometers and the internal water area is 2,543 square kilometers.
