Filtro cerámico de fundición de aluminio

Aluminio Filtro cerámico moldeado Utiliza espuma de portiforium de alta calidad y cerámica de alta pureza como materia prima, lo que permite eliminar de forma eficaz las impurezas sólidas no metálicas de la mezcla de aluminio fundido y aleaciones de aluminio en tu industria de fundición de aluminio.

Our ceramic foam filter use good portiforium foam and high purity ceramic as raw material, can removes non-metal solid mixture from molten aluminium and aluminium alloy fusant effectively in your aluminium casting industry.

Aluminum Casting Ceramic Filter Advantages
Poros de tamaño uniforme, alta porosidad, sinterización adecuada, alta resistencia a la flexión y a la compresión, filtrado eficaz.

Aluminum Casting Ceramic Filter Function
Se utiliza ampliamente en los equipos de filtrado de fusante de aluminio para la colada continua, la colada semicontinua, la colada por gravedad y la colada a baja presión.

Los filtros de espuma cerámica de alúmina se diferencian por sus especificaciones de porosidad, que van de 20 a 50 ppi, y presentan distintos tamaños y formas.
Chemial composition: Al2O3 is more than 85%, SiO2 is less than 15%.

Types of ceramic foam filter are conditioned in particular by requirements for their application. Filters for filtration of nonferrous metal alloys (casting temperature up to 1000 °C), filters for filtering cast iron with flaky and spheroidal graphite and filters intended for steel filtration are therefore used in practice. Depending on the cast material, Al2O3, SiC, ZrO2 or graphite based filters are applied.

There are several methods used to make Ceramic Filter For Casting.
The polymeric-sponge method, which will be described in more detail here, produces open-cell structures by impregnating a polymeric sponge with a ceramic slurry, which is then burned out to leave a porous ceramic.
The direct foaming method can produce both open-cell and closed-cell structures, with the foam structure more common.
In this method, a chemical mixture containing the desired ceramic component and organic materials is treated to evolve a gas.
Bubbles are then produced in the material, causing it to foam.
The resulting porous ceramic material is then dried and fired. For the honeycomb or cellular structure, a plastic-forming method called extrusion is used, where a mixture of ceramic powder plus additives is forced through a shaped die (like play dough). The cellular structure can also be produced using a pressing method.
