Ceramic foam filter is a kind of effective molten metal filter.
It's three-dimensional connected mesh skeleton structure and high porosity that make it has many advantages, such as: large surface area of slags collection, large inner surface area of filtering, Small flow resistance, good filtering effect, etc.
Ceramic Foam Filters remove metal slag and solution of metal impurities, which are far stronger effection than several of the other filters. The way of filtration is with a combination of physics and chemistry.
1. Large inclusions in the filter surface is the physical screen.
2. Interception and tiny inclusions in the role of chemical affinity and be attracted to the filter surface, side walls or pores.
Therefore,
1. It can effectively filter out impurities of various sizes, including much smaller than the pores of the filter impurities.
2. Also, it can filter and comb the whole disordered molten metal flow, reduce turbulence, allow the molten metal flow to be smooth and clean.
In accordance with its material, ceramic foam filter can be divided into Silicon Carbide, Alumina and Zirconia Ceramic Foam Filter.
