Usage
- Clean the aluminum filter box, keep it clean and intact.
- Put the ceramic foam filter into filter box carefully , press Sealing gasket around , avoid molten aluminum Dispersing or floating away.
- Use electric or gas to Preheat filter box and ceramic foam filter evenly 15-30min, make the temperature next to the molten aluminum, ceramic foam filter preheating temperature should surpass 460℃.expansion cotton will seal after heating, it makes ceramic foam filter steady in molten aluminum. preheating makes ceramic foam filter pores open and avoid occlusion expansion and contraction.
- Observe change of molten aluminum pressure, control the flowing molten aluminum needed, normal start pressure: 100-150mm. the pressure falls down bellow 75-100mm when molten aluminum flowing, it will grow later.
- Do not shock and beat ceramic foam filter in filtration. Control molten aluminum flow rate in launder.
- Take out ceramic foam filter and clean filter box after filtration.
Storage: stored in ventilated and dry environment.
Package: 5 pieces/ carton, 60 pieces/pallet.
