High Silica Fiberglass Filter Mesh For Steel Iron Copper

In casting production, the rejection rate of castings is 50 to 60% due to casting problems such as non-metallic inclusions. The inclusions do not only reduce mechanical properties of the casting, but also has a great influence on processability and appearance. For the purification of liquid casting alloys, reducing or filtering various non-metallic inclusions is an important technical measure to obtain good quality castings, and the use of fiberglass casting filters has become an important auxiliary material for purification of liquid casting alloys.

Application:

Functions:

1. It can reduce casting impurities by half and the scrap rate.

2. Filter out impurities, reduce the adverse effects of impurities on the structure and properties of casting alloys, and improve the material properties of castings.

3. Improve the machining performance of castings.

4. Improve process yield.

5. Improve the surface quality of the casting, because the impurities are filtered out, the secondary oxidation is reduced, and the surface quality of the casting is improved.

High Silica Fiberglass Fabric Filter Mesh Key Points of Usage

1. Use area of filter net: F1 = F2 / AxB

● F1: the cross-sectional area of the casting system. 

● F2: the original cross-sectional area of the casting system.

● A: the porosity of the filter screen, generally 50-60%. 

● B: the filtration rate of filter screen, generally 60-80%.

Therefore, the cross-sectional area of the casting system is generally 2-4 times that of the casting system without the casting net.

2. Position of filter screen:

● Place the filter under the sprue cup;

● Placed on the parting surface under the sprue;

● Three different positions on the lap surface of the runner.
