    Usage

    1. Clean the aluminum filter box, keep it clean and intact.
    2. Put the ceramic foam filter into filter box carefully , press Sealing gasket around , avoid molten aluminum Dispersing or floating away.
    3. 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.
    4. 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.
    5. Do not shock and beat ceramic foam filter in filtration. Control molten aluminum flow rate in launder.
    6. 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.
