Aluminum foundry foam ceramic filter uses a three-dimensional network structure and an organic bubble connected to the pores as a carrier to invade the thixotropic alumina material slurry using a square calibration center. From the automatic extrusion process, the slurry is uniformly applied to the bubble skeleton of the carrier, 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.
Aluminum foundry foam ceramic filter is suitable for the production of high quality and high requirements aluminum sheet and foil. Through physical adsorption and chemical action, it can effectively remove various oxidation inclusions generated during the aluminum smelting process, thereby reducing casting defects and improving casting quality. The next deep processing provides quality materials.
Aluminum Foundry Foam Ceramic Filter Operation
Inspect and clean the surface of the CFF filter box to keep the filter box clean and free from damage.
Gently put the ceramic foam filter into the filter box and press the sealing gasket around the CFF by hand to prevent the aluminum liquid from flowing.
Evenly preheat the filter box and filter to bring it close to the temperature of the aluminum liquid. Preheat to remove moisture and facilitate initial transient filtration. Preheating can be carried out using electrical or gas heating. Under normal circumstances, it takes about 15–30 minutes.
Pay attention to the change of the aluminum hydraulic head when 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.
During normal filtration, avoid knocking and vibrating the ceramic foam filter. At the same time, the launder should be filled with aluminum water to avoid too much disturbance of the aluminum water.
After the filtration is finished, remove the ceramic foam filter in time and clean the filter box.
