Silicon Carbide Alumina Zirconia and Honeycomb extruded ceramic filter

Nov. 22, 2022

Ceramic foam filter is a kind of effective molten metal filter.

It's three-dimensional connected mesh skeleton structure and high porosity makes it has many advantages, large surface area of slags collection, large inner surface area of filtering, small flow resistance, good filtering effect,etc.

Ceramic Foam Filters can remove metal slag and solution of metal impurities, which are far stronger than several of the other filters. It filters them with a combination of physics and chemistry.

● Physical Way: The physical screen can filter large inclusions in the mesh surface.

● Chemical Way: Intercept tiny inclusions in the role of chemical affinity and be attracted to the filter surface, side walls or pores. Therefore, to filter out effectively impurities of various sizes, including much smaller than the pores of the filter impurities.

Filter in above ways and comb the whole disordered molten metal flow, reducing turbulence, making the molten metal flow to be smooth and clean.

In accordance with its material, ceramic foam filter can be divided into Silicon Carbide, Alumina, Zirconia and Honeycomb extruded ceramic filter.
