Alumina Filter Factory focuses on the purification of aluminum melt.
With the rapid development of my country’s national economy, my country’s demand for aluminum and aluminum alloy products is increasing, and the requirements for the quality of these products are also getting higher and higher, and the consumption of the foam ceramic filter plate used in the production The amount has also increased.
Product performance of Adtech Alumina Filter
1. It can absorb large inclusions in molten aluminum, and effectively adsorb small inclusions of small size through the filter cake effect.
2. No slag drop, effectively reducing the pollution of molten aluminum.
3. Good thermal shock resistance and resistance to molten metal corrosion.
4. The size is accurate.
5. Improve the surface quality of aluminum alloy products, optimize product performance, and optimize internal structure.
Nordic Aluminium recommends the use of ceramic foam filter to everyone, but the casting process is different, I hope you can use it as appropriate.
1. Check and clean the aluminum on the surface of the box to keep the box clean.
2. Put the filter plate into the installation position of the filter box, and fix the filter plate with the pressure plate to prevent the aluminum liquid from flowing or the filter plate from floating.
3. Use gas (10-20min) or electricity (1-2h) to evenly preheat the filter element and filter plate to make it close to the temperature of the molten aluminum.
The preheating temperature of the filter plate is above 260°C.
Preheating to remove the adsorbed water can temporarily open the holes of the initial filter to prevent heat from rising and shrinking, blocking part of the holes of the filter plate.
4. Pay attention to the change of the aluminum hydraulic head during casting, and maintain the required aluminum liquid flow rate.
The normal initial pressure head is 100-150mm.
When the liquid starts to pass, the pressure head drops below 75-100mm, and the pressure head slowly increases.
5. During the normal filtering process, do not knock or vibrate the filter plate
In addition, avoid interference caused by excessive or small molten aluminum.
6. After filtering, please remove the filter plate immediately and clean the aluminum remaining in the filter tank.
Alumina Filter Factory Adtech hopes to provide high-quality products for European aluminum factories.
