Filtro de espuma cerámica

Filtro de espuma cerámica is produced basing on carrier with solid reticular structure and combined organic foam pores.
The producing procedure is as below, put carrier into the thixotropic alumina slurry, adopt square to center correcting automatic extrusion process, so that slurry evenly deposits in foam skeleton of carrier.
After drying solidification, then carrier will turn into final product by roasting formed under 1180 ℃ high temperature.
Filter is installed in the filter bowl for filtrating impurity in molten aluminum alloy, which helps to meet the requirement of production in high value-added, high-tech performance aluminum alloy precision casting.
Such as computer hard drive, PS baseboard for printing, canning materials, fan blades for turbojet engine, etc.

Ceramic Foam Filter Advantages
El filtro, que se basa en el principio de adsorción, es capaz de eliminar eficazmente las inclusiones de gran tamaño presentes en el aluminio fundido, así como de adsorber eficazmente las inclusiones más pequeñas.
No se desprenden fragmentos rotos, lo que reduce de forma eficaz la contaminación del aluminio fundido.
Resistencia superior al choque térmico; mejora la capacidad de resistencia a la erosión del metal fundido.
Producción con caudal automático, 3 procedimientos de calibración, tamaño preciso, se ajusta perfectamente al recipiente del filtro.
Mejorar el aspecto y las prestaciones de la superficie, y purificar el aluminio fundido.

Here we introduce the use of Filtro de espuma cerámica PAL
1. Inspect and clean debris on the surface of the filter box to keep the filter box clean and free from damage;
2. Put the filter plate into the filter box gently and press the sealing gasket around the filter plate to prevent the aluminum liquid from flowing or floating.
3. Evenly preheat the filter box and filter plate so that they are close to the temperature of the aluminum liquid. The preheating temperature of the filter plate is not lower than 460°C. The expanded cotton is automatically sealed by the thermal expansion. The filter plate is not easy to float and is preheated to remove the adsorbed water. Parts, more conducive to help open the initial filter aperture opening, to prevent the thermal expansion and contraction to bring some plug to the filter plate. Preheating can be electric or gas heating, normal heating 15-30 minutes;
4. Pay attention to observe the change of the aluminum hydraulic head when casting, and maintain the flow of normal demand aluminum liquid. The normal initial pressure head is 100-150mm. When the aluminum liquid starts to pass,
El penetrador descenderá por debajo de los 75-100 mm y, a continuación, subirá lentamente;
5. During the normal filtration process, avoid knocking and vibrating the filter plate. At the same time, the flow tank should be filled with aluminum water to avoid the perturbation of the aluminum liquid;
6. Una vez finalizada la filtración, retira la placa filtrante a la mayor brevedad posible y limpia la caja del filtro.

5. El resto de especificaciones se pueden personalizar según tus necesidades.

Ceramic Foam Filter employs dedicated Aluminium Ceramic Foam Filter to remove inclusions which are generated between the refining system and the mold table. The ability of the ceramic foam filter to capture these inclusions is critical to maintaining a clean ingot during the solidification of metal. Accordingly, the quality and the productivity in downstream operations such as forging, extruding, and rolling are guaranteed.

Ceramic Foam Filter mainly for filtration of aluminum and alloys in foundries and cast houses.
With the excellent resistance to attack and corrosion from molten aluminum, the filter can effectively remove inclusions, reduce trapped gas and provide laminar flow and then the filtered metal is significantly cleaner.
Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit.
