How to use ceramic foam filter

The ceramic foam filter can effectively remove all kinds of impurities in the molten aluminum, and the sealing ceramic fiber gasket is pasted around the porous ceramic filter, which helps to seal the porous ceramic filter in the filter box and ensures that no molten aluminum flows out from the side.
How to use ceramic foam filter:
1. Check and clean the debris on the surface of the filter box, and keep the filter box clean and free of damage;
2. Gently put the filter plate into the filter box, and press the sealing gasket around the filter plate to prevent the aluminum liquid from flowing or floating;
3. Evenly preheat the filter box and filter plate to make them close to the temperature of the aluminum liquid. The preheating temperature of the filter plate is not lower than 460°C. The expansion cotton will automatically seal the edge when heated and expand. The filter plate is not easy to float and preheat to remove the adsorbed water. It is more beneficial to help the initial filter pore size to open instantly and prevent thermal expansion and contraction from bringing partial hole plugs to the filter plate. Electric or gas heating can be used for preheating, and the normal heating is 15-30 minutes;
4. Pay attention to observing the change of the aluminum hydraulic head during casting, and maintain the flow control of the normally demanded aluminum liquid. The normal initial pressure head is 100-150mm. When the molten aluminum starts to pass through,
The pressure head will drop below 75-100mm, and then the pressure head will gradually increase;
5. During the normal filtration process, avoid knocking and vibrating the filter plate. At the same time, the launder should be filled with aluminum water to avoid disturbance of too large or too small aluminum liquid;
6. After filtering, take out the filter plate in time and clean the filter box.
