Asian Casting Filter used for Molten Aluminum Purification

The Asian casting filter is the most commonly used ceramic foam filter in the aluminum casting industry.

Most plants use degassing process in the treatment of molten aluminum, and use 30ppi and 40ppi CFF to filter aluminum slag.

Ceramic foam filter plates of 10-40 PPI are usually used for common aluminum castings. Ceramic filter plates of 30-60ppi are commonly used in aerospace and high-quality aluminum materials.

Asian Casting Filter

Asian Foundry Filter is an effective molten metal filter.

Its three-dimensional interconnected network structure and high porosity have many advantages, such as large slag collecting surface area. The internal surface area of filtration is large.

Alumina ceramic foam filter is one of the sizes and can be customized.

Inclusions and gases in metals can seriously affect the strength, fatigue resistance, corrosion resistance and stress corrosion cracking performance of materials.

The Asian casting filter can effectively control the oxide inclusions in the melt to improve the quality of casting rod, which is the common goal pursued by aluminum industry.

Some of the inclusions in aluminum alloy come from scrap directly, and most of them are formed in the process of melting and casting, mainly oxide inclusions.

Automobile and motorcycle wheels, steering knuckle, cylinder piston, cylinder head, aluminum ingot, aluminum and other precision casting aluminum alloy parts are all cast with aluminum alloy. Molten aluminum contains a certain amount of slag in the casting process, and the molten aluminum contacts with air. It is easily oxidized and produces impurities such as oxide scale.
