Indonesia China Foundry Filter can not only effectively remove a large number of foreign impurities in molten aluminum, but also filter out small inclusions of a few microns that cannot be removed by traditional processes. Harmful ions such as hydrogen atoms in molten aluminum are usually adsorbed on inclusions and become the core of bubble formation.

Alumina ceramic foam filter is mainly used for aluminum alloy filtration in casting and foundry workshops. CFF filter has excellent resistance to corrosion and corrosion of molten aluminum, can effectively remove inclusions and reduce residual gas.

In order to improve the purity of the aluminum alloy melt, in addition to the smelting and static purification process of the aluminum melt, the aluminum alloy purification system outside the furnace is more important.

Indonesia China Foundry Filter

Indonesia is rich in oil, natural gas, coal, tin, bauxite, nickel, copper, gold, silver and other mineral resources. The mining industry occupies an important position in the Indonesian economy, with an output value accounting for about 10% of GDP. According to Indonesian official statistics, Indonesia’s oil reserves are about 9.7 billion barrels (1.31 billion tons), natural gas reserves are between 4.8 trillion and 5.1 trillion cubic meters, and the proven reserves of coal are 19.3 billion tons, and the potential reserves can reach more than 90 billion tons.

Alumina ceramic foam filters for casting are more and more widely used in the aluminum industry. These are special filters made of materials such as silicon carbide and alumina, which provide structural stability and ensure thermal shock resistance. The ceramic foam filter can remove the oxides on the aluminum surface, thereby improving the casting quality. Today, more and more aluminum plate and aluminum foil manufacturers use AdTech’s alumina ceramic foam filter.

Generally used Indonesia China Foundry Filter are placed in the filter box. Because of their excellent resistance to corrosion and corrosion of molten aluminum, they can effectively remove inclusions, reduce air trapping, and provide laminar flow. Clean metal can produce higher-quality castings, less waste and fewer inclusions, all of which help increase profits.

After the smelting is completed, there is a large amount of scum on the surface of the aluminum alloy, mainly oxide inclusions such as Al2O3. These small inclusions are heavier than molten aluminum, but have a lighter specific gravity after agglomeration. They float on the surface and need to be slag removed. Add 0.2%~0.5% of the slag remover, evenly sprinkle on the surface of the aluminum liquid, and perform shallow stirring evenly.
