Ceramic foam filter for casting industry can remove metal slag and solution of metal impurities are far stronger than several of the other filter media, filter them with a combination of physics and chemistry. Large inclusions in the filter surface are the physical screen, interception, and tiny inclusions in the role of chemical affinity and be attracted to the filter surface, sidewalls or pores. Therefore, effectively filter out impurities from various sizes of casting products, including those much smaller than the pores of the filter impurities. Such filters and comb the whole disordered molten metal flow, reducing turbulence, allows the molten metal flow to be smooth and clean.
Ceramic Foam Filter for Casting Industry Classification
In accordance with its material, ceramic foam filter can be divided into Silicon Carbide Ceramic Foam Filter as an iron filter for molten iron, Alumina Ceramic Foam Filter as a molten aluminum filter for molten aluminum casting, and Zirconia Ceramic Foam Filter as a steel filter for molten steel casting industry.
Adtech Ceramic Foam Filters – These filters are solely used in aluminum casting. Currently, diverse sizes and thicknesses are being offered from the market-leading suppliers. You have to choose the right one as per your requirements. You can order a customized size if your requirement is not fitting to the common sizes. To avoid re-oxidation of the molten aluminum during casting, you can go for a pressure-free casting technique. It boosts the productivity of the manufacturer while keeps the filter ready for the next big consignments.
Cerazirk Filters – Mostly it is used only for iron, steel, and stainless steel casting. The most advanced ZrO2 filters changed the market scenario. For Cobalt- and Nickel-based alloy casting, this mechanism works great. Mainly it is a great performer in low-carbon as well as ultra-low-carbon steel casting.
Ceramic Filters – It is the most used and versatile option for casting aluminum, brass, bronze, copper, iron, and steel also. Mostly it is used in iron and non-ferrous casting units. You just need to find the accurate thickness of the filter to amplify the bending strength for higher productivity.
Use of vacuum degassing or AOD converter like techniques capably increases the filter capacity. For a higher performance and better durability, the right choice of filter matters.
