Filtro de espuma cerámica para metales y fundición

Ceramic Foam Filter For Metal / Casting uses a three-dimensional network structure and an organic bubble connected to the pores as a carrier to invade the thixotropic alumina material slurry.
The Ceramic Foam Filter adopts a square-corrected center-distance automatic extrusion process to uniformly apply the slurry to the bubble skeleton of the carrier, and is baked and solidified at a high temperature of 1180 ° C.
The Ceramic Foam Filter is installed in the filter box for the filtration of aluminum alloy liquid impurities to meet the high value-added, high-tech performance of aluminum alloy precision casting of aviation and transportation. Such as: computer hard disk, PS board base for printing, cans, jet turbine engine fan blades and other products. And we are a manufacturer specializing in the production of foam ceramic filter plates in aluminum plants.

Ceramic Filter For Foundry product advantages
1. It adopts the principle of adsorption to filter, which can effectively remove large inclusions in aluminum liquid and effectively adsorb fine inclusions of small size;
2. Sin escoria, lo que reduce eficazmente la contaminación del aluminio fundido;
3. Buena resistencia al choque térmico y mayor resistencia a la corrosión provocada por el metal fundido;
4. Producción en cadena de montaje automatizada, tres procedimientos de calibración, dimensiones precisas y mayor adecuación a la caja del filtro;
5. Mejorar la calidad de la superficie, mejorar el rendimiento del producto y potenciar el papel de la microestructura.

To improve the cleanliness of aluminum melt, Correct selection of Ceramic Foam Filter For Metal / Casting is Important.
The selection of the placa filtrante de espuma cerámica is firstly determined according to the amount of impurities in the aluminum melt and the degree of quality required for the final cast product of the melt transfer flow rate.
1. The amount of impurities is high, and the quality of the cast product is general. The foam ceramic filter plate with larger mesh mesh can be selected, and a glass fiber cloth coarse filter is added in front of the filter plate. At this time, it is important to use a glass fiber cloth for coarse filtration in semi-continuous casting. It can intercept the slag and the slag washed by the launder when the eye is opened.
In order to prevent blockage of the filter plate.
2. The quality of cast products is high, and the new type of foam ceramic filter with small mesh size is selected. For example, AdTech ceramic filter plate adopts three-dimensional network structure and organic bubble body connected with pores as carrier. The intrusion into the thixotropy alumina material slurry is carried out by a four-square correction center distance automatic extrusion process, so that the slurry is uniformly applied to the carrier foam skeleton, and is baked and solidified at a high temperature of 1180 ° C. It is installed in the filter box for the impurity filtration of aluminum alloy liquid, and it can meet the high-value-added and high-tech aluminum alloy precision casting of aviation and transportation. Such as: computer hard disk, PS board base for printing, cans, jet turbine engine fan blades and other products, to achieve the desired cleanliness, get good results.
3. Las especificaciones de la placa filtrante vienen determinadas por el caudal y el rendimiento total de la masa fundida. Cuanto mayor sea el caudal y el rendimiento total, y cuanto más pequeños sean los orificios de la placa filtrante, mayor será el tamaño que se elija.

Select the filter plate should also look at its color, shoot its body, burn its contents.
1. The color is pure and no impurity, indicating that the material is uniform; the hand is not sticky, indicating that the surface is not sprayed with adhesive, and will not cause secondary pollution.
2. Sujeta la placa filtrante con una mano y, con la otra en posición de aplauso, dale un golpecito suave a la placa para que caigan continuamente los residuos de ceramsita; esto indica que se trata de una placa filtrante de mala calidad, lo que provocará una contaminación secundaria del aluminio fundido.
3. Calentar con llama abierta o con un calentador eléctrico hasta que adquiera un color rojo. Enfriar inmediatamente a temperatura ambiente sin que se produzcan grietas ni escoria, lo que indica que se trata de una placa filtrante en buen estado.

The effective specific surface area or porosity calculation of the foam should be carefully evaluated when purchasing the filter. The mesh surface homogenization state of the filter plate can be observed, and then the cross-sectional mesh homogenization state is observed. If possible, the porosity can be calculated by the drainage method. The three-dimensional mesh is homogeneous and the porosity is relatively large, which is an excellent foam ceramic filter plate.
