Heat-Resistance Ceramic Foam Filter Ceramic Foam Filter for Casting

Ceramic Foam Filter
Ceramic foam filteristhe third generation of filter material after fiberglass mesh, honeycomb ceramicfilter. With its three-dimensional structure, it has excellent filtering functions of screen, filtering, residuum collection and adsorptionin filtering molten metal liquid. It has good chemical stability and does not react with alloy liquid, effectively remove the inclusion in the metal liquidto improve the purity of molten metal. It can make casting surface smooth, increasestrength,reduce the rejection rate, and reduce energy consumption, improve labor productivity, reduce costs. The ceramic foam filter is not onlyappliedfor metal filtering in high temperature, but high temperature gas treatment, carrierof catalyzer, solid heat exchanger andspecial filling for chemical industry.CeramicFoamFilterFeatures:
