Estonia China Foundry ceramic foam filter plays a vital role in the metal casting and foundry industry.
They are used to filter impurities in molten metal. Improve quality and performance.
A “filter cake” is formed on one side of the inlet filter, and deep filtration is performed inside the ceramic foam filter matrix. Therefore, these ceramic foam filters are effective tools for achieving the metallurgical purity of molten metal during the casting process.
The filter can also stabilize the filling of the mold, thereby preventing undesirable defects in the casting. The type of ceramic foam filter especially depends on its application requirements.

The structure of Estonia China Foundry Filter creates a unique tortuous path for fluid flow, which traps inclusions and allows clean, smooth-flowing metal to escape into the mold cavity. CFF is generally considered to be the best filter for casting. Their main advantages are high filtration efficiency, reduced turbulence, refractoriness, and corrosion resistance, suitable for the most demanding casting applications.

Application of Ceramic Foam Filters
1.Decontaminated the molten metal liquid
2.Simplified gating system
3.Improve the metallurgical structure of the castings
4.Reduce slag inclusions of the castings
5.Increase the casting quality rate
6.Reduce casting internal re-oxidation defects
7.Reduce the surface defects after machining of the castings

During the filtration process, the slag adsorbed on the Porous ceramic foam filters gradually grows up after adsorbing and intercepting the slag in the aluminum liquid. Under the agitation and scouring of the liquid flow, the slag with extremely low strength may be broken or removed from the ceramic filter plate. Fall off.
If the ceramic filter plate is thicker or has small holes during the slag shedding process, it may be intercepted or adsorbed again.
Therefore, in general, the thicker the ceramic plate, the smaller the holes, and the slower the flow rate of the molten aluminum through the ceramic plate, the better the filtering effect.
The total amount and cleanliness of molten aluminum basically do not affect the filtering effect, but only affect the life of the ceramic filter plate.
