Product Description

Sic ceramic foam filter is a new type molten metal filter to decrease casting flaw in recent years. With its characteristics of light-weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, erode resistance, high-performance,SIC Ceramic Foam filter is designed for filtering impurities from molten Iron & Alloy, nodular cast iron castings, grey iron castings and malleable castings, Bronze casting, etc.


Silicon Carbide Ceramic Foam Filters mainly for filtration of cast iron and non-ferrous alloys. With their excellent resistance to attack and corrosion from molten iron liquid, they can effectively remove inclusions, reduce trapped gas from liquid metal and provide laminar flow, and then the filtered metal is significantly cleaner. Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit. SiC Ceramic Foam Filters is available in all standard dimensions and different thickness. The most common porosities are PPI 10, 20 and 30; higher porosities are available upon request. Custom-made cut-to-size filters are also possible.

 

Functions:

1.Decontaminate the melting metal liquid

2.Simplified gating system

3.Improve the metallurgical structure of the castings

4.Reduce imparities of the castings

5.Improve casting quality rate

6.Reduce casting internal re-oxidation defects  

7.Reduce the surface defects after machining of the castings
