Ceramic Foam Filter

Product Description
Ceramic foam filter is a new type of material used to filter fluids such as molten metal. It has a unique structure and excellent performance and is widely used in industries such as casting.
1. Alumina:
Applicable temperature: 1250℃. Suitable for filtering and purifying aluminum and alloy solutions. Widely used in ordinary sand casting and permanent mold casting such as automotive aluminum parts casting.
Advantages:
(1) Remove impurities efficiently.
(2) Steady Molten aluminium flow and easy for filling.
(3) Reduce casting defect, improve surface quality and product properties.
2. SIC
It has excellent strength and resistance to high temperature impact and chemical corrosion, and can withstand high temperatures up to about 1560°C. It is suitable for casting copper alloys and cast iron.
Advantages:
(1) Remove impurities and improve the purity of molten metal efficiently.
(2) Reduce turbulence and even filling.
(3) Improve casting surface quality and yield, reduce defect risk.
3. Zirconia
The heat-resistant temperature is higher than about 1760℃, with high strength and good high-temperature impact resistance. It can effectively remove impurities in steel castings and improve the surface quality and mechanical properties of castings.
Advantages:
(1) Reduce small impurities.
(2) Reduce surface defect, improve surface quality.
(3) Reduce grinding, low down machining cost.
4. Carbon-based bonding
Developed specifically for carbon and low-alloy steel applications, the carbon-based ceramic foam filter is also ideal for large iron castings. It effectively removes macroscopic impurities from the molten metal while utilizing its large surface area to absorb microscopic inclusions, ensuring smooth filling of the molten metal. This results in cleaner castings and minimized
turbulence.
Advantages:
(1) Low bulk density, very low weight and thermal mass, resulting in a very low heat storage coefficient. This prevents initial molten metal from solidifying in the filter and facilitates rapid passage of the metal through the filter. Immediate filling of the filter helps reduce turbulence caused by inclusions and slag.
(2) Widely applicable process range, including sand, shell, and precision ceramic casting.
(3) Maximum operating temperature of 1650°C, significantly simplifying traditional pouring systems.
(4) Special three-dimensional mesh structure effectively regulates turbulent metal flow, resulting in uniform microstructure distribution in the casting.
(5) Efficiently filters smaller non-metallic impurities, improving the machinability of components.
(6) Improves the comprehensive mechanical properties of the casting, including surface hardness, tensile strength, fatigue resistance, and elongation.
(7) No negative impact on remelting of regrind containing filter material.
