Foam ceramic filter suppliers provide: 7 inches, 9 inches, 12 inches, 15 inches, 17 inches, 20 inches, 23 inches, 26 inches or customized according to customer requirements.
As we all know, ceramic filter plates play a very important role in the aluminum liquid purification system. Ceramic filter plates can effectively remove large inclusions in molten aluminum, effectively reduce the size of micro inclusions, and improve surface quality and product performance.
Improve the effect of microstructure and increase yield. As long as it is used for precision casting of aviation and transportation aluminum alloy. The Evans ceramic filter plate adopts a three-dimensional network structure, the organic carrier is connected with the pores, which invades the special thixotropy, the special ZrO2 high-quality molten material, and adopts the square square center-to-center automatic extrusion technology to make the slurry evenly coated on the foam On plastic. Carrier. On the skeleton, it is baked and cured at a high temperature of 1680°C, and has an extended cotton body sealing edge.
Ceramic foam filter suppliers can effectively remove various impurities in molten aluminum. Sealing ceramic fiber gaskets are installed around the filter plate to help seal the filter plate in the filter box and ensure that there is no aluminum liquid on the side.
Here, we introduce the use of zirconia ceramic filter plates:
Check and clean the surface of the filter box to keep the filter box clean and undamaged.
Put the filter plate into the filter box gently, and then press the sealing strip on the filter plate to prevent the aluminum liquid from flowing or floating.
Preheat the filter box and the ceramic foam filter plate uniformly to make it close to the temperature of the molten aluminum. The preheating temperature of the filter plate is not less than 460℃. The expanded cotton cloth is automatically sealed by thermal expansion.
The filter plate does not float easily and needs to be preheated to remove the adsorbed water.
These components help to open the opening of the initial filter and prevent thermal expansion and contraction from bringing some plugs to the filter plate. Preheating can be heated by electricity or gas, and usually takes 15-30 minutes.
Pay attention to observe the change of the molten aluminum head during the casting process to maintain the normal demand of molten aluminum flow. The normal initial nozzle is 100-150mm.
The indenter drops below 75-100mm, and the indenter slowly increases.
In the normal filtration process, knocking and vibration of the filter plate should be avoided.
At the same time, the water tank should be filled with molten aluminum to avoid disturbing the molten aluminum.
After filtering, please remove the filter plate and clean the filter box in time.
