Use Aluminum Casting Filter in the ceramic foam filter cff box machine, and it’s best that inspect and clean the surface of filter bowl.

Use Filtro para fundición de aluminio en el filter CFF bowl unit, and press sealing gasket around the foam ceramic filter by hand to prevent molten aluminum from dispersing or floating away.

Use electric or gas burning to preheat filter bowl and ceramic foam filter evenly for 15-30 minutes, to make sure their temperature close to molten aluminum.
The preheating temperature for ceramic foam filter should above 260℃.
Expanding cotton will seal after preheating.
This procedure makes sure that ceramic foam filter steady fixed in molten aluminum.
Preheating also leads ceramic foam filter pores open and avoid occlusion caused by thermal expansion and contraction.

Observe the change of molten aluminum height, hold molten aluminum flow in standard needs.
Normal starting molten aluminum height is 100-150mm.
The height falls down below 75-100mm when molten aluminium flows, and it will slowly increase later.

Do not hit or shake ceramic foam filter in filtration. At the same time, control molten aluminium flow rate in launder, never to be too much or too little.
Retira el filtro de espuma cerámica y limpia el recipiente del filtro a tiempo tras el filtrado.
