Molten Aluminum Filter Bangladesh Aluminum has the characteristics of a large filtering area, good thermal shock stability, high chemical stability, good metal corrosion resistance, and good filtering efficiency. It is a filter element widely used in aluminum melt filtration and purification technology, which has attracted the attention of aluminum melting and casting plants.
Foam Ceramic Filter Foundry is an alumina-based ceramic foam filter, which can be widely used for filtering in the casting process of aluminum, aluminum alloy, and other non-ferrous metals. Such filters can be placed in standard filter boxes, holding furnaces, etc.
Since the 30ppi filter foundry filters out solid slags such as metal oxides contained in the molten metal during the casting process, thereby improving the quality and yield of castings, the use of ceramic foam filters has driven technological progress in the casting industry. Has been promoted.
Ceramic foam filters are basically divided into 6 types of pore sizes: 10PPI, 15PPI, 20PPI, 25PPI, 30PPI, and 40PPI. The larger the number, the smaller the aperture. But in actual operation, the four types of 10PPI 20PPI 30PP 40PPI can meet the needs of customers.
1. Casting: 10～25ppi
2. Semi-continuous casting: 30～60ppi
3. High-quality aluminum or plate: 50～60ppi
4. Continuous casting and rolling: 50～60p
Effect of Molten Aluminum Filter Bangladesh Aluminum
In order to reduce the inclusions in the pouring process, the gating system often tries to prevent the inclusions in the molten aluminum from entering the cavity before the molten aluminum enters the cavity.
If there are serious inclusions in the pouring process, the height and length of the runner should be increased as much as possible, and the volume of the slag bag should be increased, thereby reducing the casting yield.
Reduce machining allowance and improve cutting performance
In process design, the non-machined surface of the casting is often cast upward. This is because the upper part of the mold often contains inclusions, which are not easy to detect when they are left on the unprocessed surface.
