Filtration is an important way to purify aluminum alloy melts

Filtration is an important way that can purify the aluminum alloy melts.

It can improve the foundry properties of the aluminum alloy melts by filtration treatment. 

There are many reasons for aluminum pollution.

On the one hand, in the smelting process, aluminum is exposed to the furnace atmosphere in a molten or semi-molten state, easy to oxidize, easy to react with water vapor and absorb hydrogen, easy to form various forms of non-metallic slag (such as furnace lining debris, chloride, carbide in flux, etc.) and coarse metal intercompound particles and so on. 

On the other hand, non-aluminum impurities are carried in during the process circulation by some of waste materials maked up the charging material.

We, Hebei CangChen can customize a series of filters that can be used for filtration of aluminum liquid.

Let's see what kind of foundry filters we can provide:

1. Alumina Ceramic Foam Filter Plate

Alumina Ceramic Foam Filter Plate is mainly used in the melting filtration of aluminum and aluminum alloys.

It can efficiently filter residues such as oxide slag, oxide scale, non-metallic inclusions and gate groove linings in molten aluminum, and solve the problem of aluminum and aluminum alloys being sensitive to internal defects.

The unique production process and detection method make the alumina filter plate with high opening rate, uniform pore structure and high surface strength.

Available in 7" to 26", mesh up to 60ppi filter plates.

2. TF Combo Bag

TF Combo bag, also named Fiberglass thermally fused shunt combo bag, which is weaved by special high-twist & high-strength alkali-free fiberglass yarn, special post-treatment, coated with special phenolic resin and carbonized by high temperature. Its withstand temperature up to 1000 °C.

Apply to large Dia. aluminum ingot/billet/ slab.
