Czech China Foundry Filter is mainly used in metallurgy and foundry industries to filter impurities in molten aluminum, reduce porosity, eliminate turbulence in metal flow, and improve casting quality.

When the speed of aluminum liquid flowing through the Foundry Filter is too low, it is not easy to be adsorbed due to the collision probability of small inclusions, and flows “steadily” through the filter holes. When the speed is too high, the molten metal stream will “wash away” solid inclusions and may carry them away. The best flow rate should be determined by production practice.

The foams we use for ceramic filters meet the highest quality standards and have excellent uniformity.
They have a variety of pore sizes and can be used for aluminum in ceramic filters.
We have two types of ceramic foam filters-pal and ceramic foam filters-pzr.

The aluminum liquid filtration method mainly allows the aluminum melt to pass through a ceramic filter to separate the suspended solid inclusions in the melt. This method mainly removes inclusions in the melt, and has little effect on hydrogen removal.

Through these three filtration and purification mechanisms, large-volume inclusions and a large number of suspended inclusions as small as tens of microns in liquid metal can be effectively removed.
The filtration efficiency of the ceramic foam filter is as high as 95%, while the filtration efficiency of the double-layer fiber filter is only 67%, which significantly reduces the rejection rate of castings and the rate of welding repairs.
In addition, it can also simplify the pouring system, improve the metallographic structure, increase the yield and productivity of the casting process, and improve the internal quality, work performance and processing performance of the casting.
Therefore, Czech China Foundry Filter has a good application prospect and application market.

The Czech Republic borders Slovakia to the east, Austria to the south, Poland to the north, and Germany to the west. It has an area of ​​78866km², of which the land area is 77276km² and the water area is 1590km². It is composed of three parts: Bohemia, Moravia and Silesia.

The Czech Republic is rich in lignite, hard coal and uranium deposits. The reserves of lignite and hard coal are about 13.4 billion tons, ranking third in the world and fifth in Europe respectively. Oil, natural gas and iron sand reserves are very small and rely on imports. Other mineral resources include manganese, aluminum, zinc, fluorite, graphite and kaolin.

There is a large hydropower station on the Vltava River. Can provide abundant electric energy.
