Product Description

Silicon Carbide Ceramic Foam filter

Silicon carbide ceramic foam filter is designed for filtering ductile iron, grey iron, and non-ferrous alloy castings. With excellent resistance to attack and corrosion from molten iron liquid, it can effectively remove inclusions in molten metal, and adsorbed impurities, reduce the molten metal in the gas and the harmful element content, decrease the reject rate, and improve the processing performance and mechanical properties of the casting.

Advantages:

Good filtering effect, and reduces the reject rate.
Strong adsorption function, reduces inclusions.
Reduce turbulence and even filling
improve casting processability and mechanical properties.

Product Applications

Key Applications of SiC Ceramic Foam Filters:

A. Specific Casting Products:

Automotive Castings: Engine blocks, cylinder heads, brake discs/drums, turbocharger housings.
Aerospace & Gas Turbine Castings: Superalloy turbine blades, engine structural components, nozzle guides.
High-End Industrial Castings: Pump & valve bodies (stainless steel/ductile iron), wear-resistant parts, large gears.

B. Specific Casting Processes:

Sand Casting: Placed in the gating system to capture slag and inclusions.
Investment Casting (Lost-Wax): Used in the wax tree assembly for high-purity superalloy filtration.
Lost Foam Casting: Filters pyrolysis products from the decomposing foam pattern.
Gravity & Low-Pressure Die Casting (for non-ferrous alloys): Purifies molten aluminum/copper alloys before filling the mold.
