Aluminum Casting Filter Agent

Aluminum Casting Filter Agent

AdTech authorized aluminum casting filter agent to sell alumina ceramic foam filters to local aluminum smelters and foundries.

Alumina ceramic foam filters are installed on the CFF BOX machine to filter liquid impurities in aluminum alloy to meet the high value-added, high technology performance of aviation, transportation and other aluminum alloy precision casting production.

Aluminum Casting Filter Agent should understand that the quality of aluminum melt is very important, which greatly affects the subsequent processing performance and the quality of the final product. Therefore, all countries in the world are eager to purify aluminum melt.

There are many reasons for aluminum pollution. On the one hand, in the melting process, aluminum is exposed to the atmosphere in the furnace in molten or semi molten state, which is easy to oxidize, react with water vapor to absorb hydrogen, and form various forms of non-metallic slag (such as furnace lining debris, chloride, carbide in flux, etc.) and coarse intermetallic particles.

On the other hand, some non aluminum impurities will be introduced into the waste materials which make up the furnace charge.

Because the waste comes from the process waste, geometric waste and other waste materials of various processes in the factory, the path is different, the composition is complex and the quality is poor.

These impurities usually cause bubbles and inclusions in the slab, which seriously affect the purity of the molten metal, and further affect the processability, mechanical properties, corrosion resistance and product appearance quality.

Nowadays, there are many ways to remove these harmful substances and purify aluminum melt.

According to different methods, these methods can be divided into two types: in furnace treatment and external continuous treatment (i.e. on-line treatment).

According to the function, it can be divided into two types: degassing or slag removing. Ceramic foundry filter manufacturers introduced continuous filtration of aluminum melt using foam ceramic filter plate. External continuous treatment, the main purification operation is to remove slag.

The ceramic filter used in casting has a certain strength mesh structure, which can withstand the influence of pressure difference of metal surface and metal flow, but it is brittle and brittle. Due to its precise structure, uniform mass and large surface area, the filtration effect is excellent.
