How to choose Ceramic Foam Filter? Ceramic Foam Filter Manufacturers AdTech Metallurgical Materials Co.,Ltd. will tell you.

1. There are many impurities, and the quality of cast products is general. Ceramic filter plates with larger meshes are available, and a glass cloth coarse filter is added in front of the filter plates. At this time, semi-continuous casting is important for coarse filtration with a glass cloth. It can intercept the slag from the opening of the eye and the slag washed out by the launder to prevent clogging of the filter plate.

2. The quality requirements of cast products are high, and the new type of foam ceramics with large mesh size is selected.

3. The specification of the ceramic filter plate is determined by the flow rate and total throughput of the melt.

4. 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.

5. The effective specific surface area or porosity calculation of the foam should be carefully evaluated when purchasing the filter.
Se puede observar el estado de homogeneización de la superficie de la malla de la placa filtrante y, a continuación, se observa el estado de homogeneización de la malla en la sección transversal.
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 ceramic filter plate.

How to use Ceramic Foam Filter? Ceramic Foam Filter Manufacturers AdTech Metallurgical Materials Co.,Ltd. will tell you.

1. Limpia la caja del filtro.
2. Gently put the ceramic filter plate into the filter box and press the sealing gasket around the ceramic filter plate by hand to prevent the aluminum liquid from flowing.
3. Precalentar uniformemente la caja del filtro y la placa filtrante para que alcancen una temperatura cercana a la del aluminio fundido. El precalentamiento sirve para eliminar la humedad y facilitar la filtración transitoria inicial. El precalentamiento puede realizarse mediante calefacción eléctrica o de gas. En circunstancias normales, dura entre 15 y 30 minutos aproximadamente.
4. Pay attention to the change of aluminum hydraulic head during casting. The normal starting pressure head is 100-150mm. When the aluminum liquid begins to pass, the pressure head will drop below 75-100mm, and then the pressure head will slowly increase.
5. Durante el proceso normal de filtración, evite golpear o hacer vibrar la placa filtrante. Al mismo tiempo, la canaleta debe estar llena de agua de aluminio para evitar que esta se agite en exceso.
6. Una vez finalizada la filtración, retira la placa filtrante a la mayor brevedad posible y limpia la caja del filtro.
