Foam Ceramic Filter is a kind of filter which is made of polyurethane foam plastic as a carrier by dipping ceramic powder, adhesive and other materials and roasting at high temperature. Foam Ceramic Filter has a porous structure that can efficiently filter inclusions in metal melt, improving the quality and yield of metal castings.
Silicon carbide has excellent strength and resistance to high temperature impact and chemical corrosion. They can withstand high temperatures up to approximately 1560 ° C. Therefore, they are suitable for casting all copper alloys and cast iron. The Foam Ceramic Filter can significantly improve the quality of cast iron parts and reduce the scrap rate. It can also be used in the continuous casting and rolling process, and can be manufactured into all standard sizes and different thicknesses.
The basic materials of Foam Ceramic Filter include silicon carbide, zirconia and alumina.
The Foam Ceramic Filter has an excellent filtering effect on molten copper or iron. By using three-dimensional structure, oxidation inclusions and other non-metallic inclusions can be effectively removed by blocking, trapping and adsorption.
