Application :

Silicon carbide ceramic foam filters are the right choice for iron casting. Ceramic foam filters have a manimum application temperature of up to 1470 centigrade and are basically suitable for all types of iron alloys, including alloyed cast iron. The application of 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.
