Usage
- Clean the aluminum filter box, and keep it clean and intact.
- Put the ceramic foam filter into the filter box carefully, press the Sealing gasket around, and avoid molten aluminum Dispersing or floating away.
- Use electricity or gas to Preheat the filter box and ceramic foam filter evenly for 15-30min, and make the temperature next to the molten aluminum, and ceramic foam filter preheating temperature surpass 460℃. expansion cotton will seal after heating, it makes the ceramic foam filter steady in molten aluminum. preheating makes ceramic foam filter pores open and avoids occlusion expansion and contraction.
- Observe the change of molten aluminum pressure, and control the flowing molten aluminum needed, normal start pressure: 100-150mm. the pressure falls below 75-100mm when molten aluminum flows, it will grow later.
- Do not shock and beat the ceramic foam filter infiltration. Control molten aluminum flow rate in launder.
- Take out the ceramic foam filter and clean the filter box after filtration.
