SILICON CARBIDE CERAMIC FOAM FILTER
Silicon carbide ceramic foam filters are designed for filtration of grey iron,ductile iron,and nonferrous alloy. It has a maximum application temperature of up to 1470 centigrade. The application of silicon carbide ceramic foam filters has various advantages. One is that the flow of metal is effectively calmed-down due to the complex 3D structure of the filter, thus sand erosion is reduced and the filling of mould is improved. Another advantage is that the ceramic filter removes solid inclusions like e. G. Slag or reaction products of melt treatment from the liquid metal. Therefore, the metal quality is improved and cleaning and repair work is reduced.
l good filtering effect, reduce the reject rate.
l strong adsorption function , reduce inclusions.
l improve casting process ability and mechanical properties.
