Molten Aluminum Filter Manaksia Aluminium is a porous ceramic with a high porosity (80%～90%) with a three-dimensional grid structure. Because of its low density, high strength, high-temperature resistance, corrosion resistance, and good filtration and adsorption properties.
In recent years, through the development of the third-generation aluminum Molten Aluminum Filter, the pass rate of metal smelting products to finished products has been greatly improved, and the performance of its products has also been greatly improved. . Yes.
Molten Aluminum Filter Manaksia Aluminium is one of the most widely used industries. Its function is to make the turbulent and agitated metal liquid pass through the foam ceramic honeycomb pores to become a stable, uniform, and clean metal liquid.
Thereby, the rejection rate of castings caused by casting defects such as non-metallic inclusions is significantly reduced, and the production cost is saved.
Aluminum CFF uses polyurethane foam as a carrier and is immersed in a ceramic solution made of ceramic powder, binder, sintering aid, suspending agent, etc.
Then squeeze out the excess slurry, so that the ceramic slurry is evenly coated on the green body on the carrier skeleton.
The green body is dried and sintered at high temperatures. This process is also known as the organic foam impregnation method, and it is a foam ceramic production process commonly used in households at present.
Alumina ceramic foam filter is an important branch of the three major types of ceramic foam filter (alumina, silicon carbide, and zirconia), and it is also the oldest type of ceramic foam filters. It is widely used in the aluminum and alloy casting industry.
At present, with the continuous improvement of the performance requirements of aluminum and aluminum alloy products, new requirements are continuously put forward for the filtration of molten aluminum to meet the requirements of high purity, low floating balls, and smooth flow rate of the molten aluminum. .Aluminum products have better physical and chemical properties and mechanical processing properties to meet more demanding conditions and achieve the purpose of extending the service life of aluminum products.
Every process in the production of foam ceramics has an impact on the quality of foam ceramic products, among which the main process materials, sponge processing, and sintering have the greatest impact on product quality. The spraying process mainly affects the quality and appearance of the product, but also has a certain impact on the internal quality.
