Refractory Filtration Treatment

Refractory Filtration Treatment can reduce aluminum melt casting defects, make liquid metal more pure, and greatly reduce the occurrence of waste problems such as blistering and holes. The molten metal foam filter has excellent thermal shock resistance, chemical resistance and high temperature stability.

The ceramic foam filter of the aluminum factory is made of non-stick aluminum material, which has the characteristics of non-stick aluminum.
The product is white or milky white.
Refractory Filtration Treatment is suitable for the purification process of aluminum and aluminum alloys with high requirements through physical adsorption and chemical action.
It can effectively remove various oxide inclusions produced during the aluminum smelting process, thereby reducing casting defects, improving casting quality, and providing high-quality aluminum.

Filters in aluminum plants should be preheated before use. The filter plate is completely sealed in the aluminum water casthouse to ensure that all the aluminum water passes through the CFF casthouse, and the total filtering capacity does not exceed the specified limit.
If the slag content in the aluminum water is too high, it should be filtered or reduced several times. The amount has been adjusted.

Advantages of molten metal foam filter
1.3d grid structure
2. High mechanical strength, no residue in beating
3. High porosity
4. Large specific surface area, strong adsorption of impurities
5. Excellent thermal shock resistance

Refractory Filtration Treatment

Metal foam filter is the best way to eliminate non-metallic inclusions in aluminum solution. These inclusions are the main source of casting quality problems.
When casting products, remove impurities in molten metal, refractory waste, solid refractory alloys and sintered ore, eliminate turbulence, reduce porosity of castings, and improve casting quality.
Therefore, our metal foam filters are widely used in the aluminum casting industry to prevent defects such as oxides, scum, gas, slag and other impurities.

The turbulence in the metal flow is eliminated, the metal flow is stabilized, and spray, splash and collapse are avoided. Improve fluidity, castability, processability, yield and cost-effectiveness. Remove a larger proportion of fine particles, reduce waste, rework, and low pressure loss. Provide consistent flow and capacity.

Sweden Aluminum said that the Cff foam filter produced by the filter factory has excellent performance and is suitable for purification and filtration of high-temperature aluminum and aluminum alloy solutions.
Filter non-metallic slag and micron slag to make the surface of castings smooth and reduce processing loss.
The filter makes the molten aluminum fill the cavity more evenly. During the casting process, the molten metal has a tendency of greater turbulence.
Finally, the turbulent flow through the three-dimensional pore structure is transformed into a very stable laminar flow, which better fills the cavity, thereby reducing the metal solution pair.
The impact chamber is corroded, which greatly reduces the rejection rate, reduces production costs, and improves labor productivity.
