Ceramic Foam Foundry Filter is mainly used for the filtration of aluminum and aluminum alloy in the foundry. It is widely used in continuous casting, semi-continuous casting, gravity casting, and low pressure casting aluminum penetration filtration equipment. It can effectively remove inclusions, reduce trapped gas, and provide laminar flow when molten aluminum is filtered.
Aluminia ceramic foam filter used in the scope of:
Alumina ceramic foam filter is widely used in continuous casting, semi-continuous casting, gravity casting and low pressure casting aluminum welding filter equipment.
Alumina ceramic foam filter specifications:
We can produce alumina ceramic foam filters in square and other geometric shapes. The thickness is 50mm, and the hole density is from 10ppi to 60ppi.
A gasket is installed on the edge of the aluminum ceramic foam filter. The gasket puts the clean and tight position of the filter in the filter box. You can also choose alumina ceramic foam filter with the gasket.
Our ceramic foam filter uses high-quality port foam and high-purity ceramics as raw materials, which can effectively remove the non-metallic solid mixture of molten aluminum and aluminum alloy flux in the aluminum casting industry.
Uniform pore size, high porosity, correct sintering, high bending and compressive strength, and effective filtration.
It is widely used in continuous casting, semi-continuous casting, gravity casting and low pressure casting aluminum flux filter equipment.
The pore size of the alumina ceramic foam filter ranges from 20 to 50ppi, with different sizes and shapes. Chemical composition: Al2O3 is greater than 85%, SiO2 is less than 15%.
Ceramics Foam Foundry Filter has high thermal conductivity, excellent resistance to aluminum melting and aluminum adhesion, and can prevent the temperature drop of molten metal and improve the quality of molten metal.
Since it burns at a temperature of 1,250°C, it is thermally stable in the molten metal temperature range (up to 850°C or lower), and its strength does not decrease.
Ceramic Foam Foundry Filter Features:
It has high strength, low particle expansion and excellent thermal shock.
It can heat up and increase the temperature when it is installed in the furnace.
The shape can be manufactured without secondary processing.
In addition to the flat shape, corners, drill holes, notches, and ribbed C and R surfaces can also be machined.
The filter box can also be manufactured by bonding.
Since no secondary processing is required, particles on the shape processing surface can be prevented from falling off and the strength can be reduced, and there is no problem caused by the filter.
