Foundry Filter

Ceramic Foundry Filter-Pure aluminum liquid, used for high-precision filtration purification of rail transportation, aerospace products, etc.
The Aluminum Ceramic Foundry Filter has a sealing lining around it that acts on the filter plate and the filter box.
Preventing aluminum liquid from leaking through the contact surface.
Our Ceramic Foundry Filter uses three different types of sealing gaskets: fiber paper edge; fiber cotton edge; expanded cotton edge.

How to Select Aluminium Ceramic Foundry Filter
1. The amount of impurities is high, and the quality of the cast products is general. The Aluminium Ceramic Filter with larger mesh holes can be used, and a glass fiber cloth coarse filter is added in front of the filter plate.
At this time, semi-continuous casting is important for coarse filtration with a glass cloth. It can intercept the slag from the opening of the eye and the slag washed out by the launder to prevent clogging of the filter plate.
2. The quality requirements of the cast products are high, and the ceramic mesh is small, that is, the Ceramic Foundry Filter with a large number of meshes.
3. The choice of Ceramic Foundry Filter specification is based on the flow rate and total throughput of the melt.
4. The color is pure and no impurity, indicating that the material is uniform; the hand is not sticky, indicating that the surface is not sprayed with adhesive, and will not cause secondary pollution.
5. The effective specific surface area or porosity calculation of the foam should be carefully evaluated when purchasing the filter.
The mesh surface homogenization state of the filter plate can be observed, and then the cross-sectional mesh homogenization state is observed.
If possible, the porosity can be calculated by the drainage method. The three-dimensional mesh is homogeneous and the porosity is relatively large. It is an excellent Ceramic Foundry Filter.

The Merits of Foundry Filter
Reduce gas and inclusions that are contained in the casting, reduce the turbulence level of molten metal when filling the mold, reduce surface defects in castings, and significantly reduce the rejection rate of casting
Increase the compressive sealing of casting, increase elongation and tensile strength of casting, improved surface finish of casting, improve the mobility of molten metal, increase the filling capacity and the feeding capacity of melt.
Simplify the casting system, reduce the length of the lateral flow channel, improve casting yield.
Reduce the processing time and tool abrasion, improve surface quality of casting.
Ceramic foam possesses high mechanical strength, chemical stability, high resistance to thermal shock and liquid metal flow shock even under high temperature environment.
No slag or broken in working process, to ensure the quality and stable chemical composition of the molten metal.
Has a large and stable metal flow, even if the high content of inclusions in molten metals, ceramic foam filter will not be plugged.ery high dimensional accuracy, can be automatically placed in production line.
