Alumina Ceramic Foam Filter For Metal, like a sieve, prevents inclusion particles and their agglomerates whose size is larger than the pore size of the filter surface.
Cast aluminum is a process in which aluminum in a molten state is poured into a mold and cooled to form aluminum parts of the required shape. The aluminum used in cast aluminum is called cast aluminum alloy.
Cast aluminum: It is a kind of pure aluminum or aluminum alloy ingot prepared according to the standard composition ratio, and then artificially heated to turn it into the aluminum alloy liquid or molten state, and then the aluminum liquid or the molten state through a professional mold or corresponding process A process in which aluminum alloys are poured into the cavity and cooled to form aluminum parts in the required shape.
Inclusions and gases in the metal have a major impact on the strength, corrosion resistance, and stress corrosion cracking performance of the material.
Effectively controlling the oxidized inclusions in the melt to improve the quality of cast rods and rolled plates has become a common goal pursued by the metallurgy, casting and material industries of all countries.
Currently, filtration and purification methods are widely used to remove inclusions in aluminum alloy melts.
Function of Alumina Ceramic Foam Filter For Metal
Removal of impurities
Purify the aluminum alloy liquid, the viscosity of the aluminum alloy liquid decreases after filtration, and the fluidity of the aluminum alloy liquid increases by 10%-15%. Therefore, filtration improves the filling capacity of aluminum alloy liquid.
The flow of the aluminum alloy liquid before filtration is turbulent, and after filtration, it becomes laminar (the flow channel of the foam ceramic filter is twisted and turned), which reduces entrainment and secondary slagging.
As the filtration progresses, the filtration mechanism changes from sieving, filter cake to deep bed filtration, and the purity of the aluminum alloy after filtration is getting higher and higher (without exceeding the maximum filtration capacity of the ceramic foam filter).
For example, the aluminum alloy liquid in the combustion chamber at the bottom of the cylinder head is the purest.
Reduced scrap rate of parts
Improved part cutting performance
The mechanical properties of materials are significantly improved, especially the elongation.
Alumina Ceramic Foam Filter For Metal is the last process of aluminum melt purification treatment.
It needs to be specially pointed out that it is necessary to prevent the secondary pollution of the melt that may occur during the process of solidification and forming after the aluminum melt leaves the filter box.
In this process, use long-life, high-strength, non-stick aluminum, and good thermal insulation fused silica ceramic sintering trough, front box, distribution plate, and hot cap, and timely dehumidification and cleaning to eliminate possible pollution sources .
It cannot be ignored to ensure the cleanliness of the aluminum melt.
