30ppi filter for aluminum foundry has the characteristics of large filtration area, good thermal shock stability, high chemical stability, metal corrosion resistance and high filtration efficiency.
Therefore, the metal melt filtration purification technology, as a new type of high-efficiency filter, has been concerned by aluminum melting and casting plants.
Foam ceramic filter foundry is an alumina-based ceramic foam filter, which can be widely used for filtration in aluminum, aluminum alloy and other non-ferrous metal casting processes. This type of filter can be placed in a standard filter box, holding furnace, etc.
30ppi Filter for aluminum Foundry is used to filter solid slag such as metal oxide in molten metal in casting process, so as to improve the quality and output of castings. The use of ceramic foam filters has promoted the technological progress of the foundry industry.
Ceramic foam filters are basically divided into 6 pore sizes: 10PPI, 15PPI, 20PPI, 25PPI, 30PPI and 40PPI. The larger the number, the smaller the aperture. But in practice, four types of 10ppi 20ppi 30pp 40ppi filter for aluminum foundry can meet the needs of customers.
Aperture selection
1. Casting: 10 ~ 25ppi
2. Semi continuous casting: 30 ~ 60ppi
3. High quality aluminum plate: 50 ~ 60ppi
4. Continuous casting and rolling: 50 ~ 60p
Application effect of ceramic foam filter
Saving metal
In order to reduce the inclusions in the casting process, efforts are usually made in the casting system to try to keep the inclusions in the molten aluminum in the casting system before entering the cavity.
If the inclusions are very serious in the casting process, every effort should be made to increase the height and length of the runner and the volume of the slag bag, so as to reduce the production of the casting.
Reduce machining allowance and improve cutting performance
In process design, the non machined surface of castings is usually poured upward. The reason is that there are often inclusions in the upper part of the mold, and it is not easy to find the inclusions when the inclusions remain on the non machined surface.
