5052 Aluminum Molten Metal Filtering is based on polyurethane foam as a carrier, immersed in a coating made of ceramic powder, binder, sintering aid, suspending agent, etc., to extrude the excess coating. The ceramic coating is uniformly coated on the carrier frame to form a green body, and then the green body is dried and baked at a high temperature.
Organic foam has a three-dimensional network structure. Put the foam carrier into a special ceramic slurry with thixotropic properties. The technician then uses a special roll extrusion process to evenly coat the ceramic slurry on the carrier. After the final ceramic filter plate is dried and solidified, it is fired at a high temperature. There is a sealing gasket around the ceramic filter plate. It is mainly used for the contact surface of the filter plate and the filter box to prevent the aluminum liquid from leaking through the contact surface. AdTech ceramic foam filter uses three different materials of sealing gaskets: fiber paper, fiber cotton, and expanded cotton.
5052 Aluminum Molten Metal Filtering can reduce the turbulence of the molten aluminum and carry out rectification and purification of the molten aluminum.
The filtered and purified aluminum castings can significantly extend the service life of parts with high demand such as aviation and auto parts, and also have good effects on aluminum and copper parts that require surface polishing.
Foam ceramic filters also play an important role in the traditional aluminum industry, electrical aluminum industry and continuous casting and rolling processes.
Because aluminum and its alloys have a large specific gravity and produce large thermal shocks during casting, the alumina foam ceramic filter used in the aluminum casting process generally has strict regulations on the size.
Alumina has excellent strength and resistance to high temperature impact and chemical corrosion.
Therefore, it is suitable for the casting of all aluminum alloys.
The alumina ceramic foam filter can significantly improve the quality of cast aluminum parts and reduce the rejection rate.
Alumina ceramic foam filters can also be used in continuous casting and continuous rolling processes, and can be manufactured into various standard sizes and different thicknesses.
With the rapid development of the foundry industry, the requirements for the cleanliness and casting performance of the molten metal are getting higher and higher.
In recent years, molten metal foam ceramic filters foundry has been widely used in casting production and have become the simplest and most effective method to improve the mechanical properties of castings and reduce porosity and inclusions.
At present, there are more and more manufacturers of molten metal foam ceramic filters in my country, and the output and consumption of foam ceramic filters have also increased significantly.
