Placa filtrante cerámica de espuma de alúmina para la limpieza del aluminio fundido

Placa filtrante cerámica de espuma de alúmina is used in the Aluminium metallurgical industry and foundry to clean metal melt from non-metallic inclusions and oxide films, which helps to eliminate many shortcomings, improve the quality of the metal, reduce the amount of scrap during casting and also solve other production problems. TU / GOST:

Alumina Foam Ceramic Filter Plate Product description
Increasing the uniformity of the internal structure of the metal;
Improvement of mechanical properties;
Elimination of metallurgical imperfections (gas sinks, porosity, leaks);
Surface quality improvement;
A significant improvement in the machinability of products, reducing the cost of their processing;
Descenso en el número de matrimonios.
Ceramic foam filters of three-dimensional structure of various shapes (circle, oval, rectangle, square), sizes, thicknesses (12-50 mm) and porosity (8-70 ppi – pore per linear inch) are offered, depending on the needs and requests of customers.
Filter application temperature – up to 1700 ° C (with short-term use, higher temperatures are also possible). To ensure optimal filter efficiency, they must be preheated.
Three types of ceramic foam filters are offered, which are made on the basis of:
aluminum oxide (for filtering aluminum at temperatures up to 1150 ° C);
zirconium dioxide (for filtering steel, as well as alloys based on nickel and cobalt, at temperatures up to 1700 ° C). Special application – casting of magnesium;
carburo de silicio (para el filtrado de hierro dúctil y hierro fundido dúctil, así como de metales no ferrosos a temperaturas de hasta 1420 °C).
Para productos especialmente críticos, se pueden utilizar filtros dúplex, cuya característica distintiva es la combinación de dos tipos de porosidad en un único filtro de tamaño estándar: porosidad PPI 10/30 con dimensiones a partir de D 100 × 25 mm.
It is possible to use filters at various points of the foundry system: horizontally or vertically along the way, at the base of the gate or profit.
In addition, when casting, due to the three-dimensional structure of the filter, the metal flow is effectively stabilized, the form is filled more smoothly and evenly. Due to this, the deoxidation of the metal in the mold, as well as the erosion of the moldable mixture, is significantly reduced.
