Product Description

Alumina Ceramic Foam Filters

Alumina ceramic foam filters are mainly used to produce aluminum and aluminum alloy purification processes. With increasing requirements for high-quality aluminum products, the application of alumina ceramic foam filters will be more extensive.

 

Alumina ceramic foam filter application:

1. Effectively eliminate the bulk of molten aluminum inclusions.

2. Removed small size of several microns inclusions in the normal process of molten aluminum. At the same time, the ceramic foam filter reduces the small inclusions, effectively reduces the number of nucleus in the liquid aluminum, and shortens the solidifying time, organizations are refined.

3. Reduce the hydrogen content in liquid aluminum. Hydrogen atoms can be adsorbed in oxide inclusions, which can be the core of gas generation. Removing the inclusion also filters the gas.

4. It can remove the harmful elements in molten aluminum (Na K).
 

Alumina ceramic foam filter use
1. Clean the filter box.
2. Gently put the filter into the filter box, and press the gasket around the filter to prevent the molten aluminum from flowing from the side.
3. Even preheat the filter box and filter plates, closer to the temperature of molten aluminum casting.
4. Observe the aluminum liquid hydraulic head change, the normal initial pressure head is 75-150 mm. When the Alumina liquid begins to pass, the pressure head will be reduced to 25 mm below, then the pressure head will gradually increase.
5. After filtration, timely remove the filter plate, and clean the filter box.

Alumina ceramic foam filter selection
In general, choosing an alumina ceramic foam filter should consider the requirements of finished product quality, the flow capacity of the molten aluminum tank, the amount of the total filtration of molten aluminum, aluminum liquid cleanliness, and other factors.
The choice of alumina ceramic foam filter is as follows, it is just for customer reference.

Dimension inch	Dimension mm	Pore size PPI
23*23*2	584*584*50	20/30/40/50
20*20*2	508*508*50	20/30/40/50
17*17*2	432*432*50	20/30/40/50
15*15*2	381*381*50	20/30/40/50
12*12*2	305*305*50	20/30/40/50
9*9*2	228*228*50	20/30/40/50

We also can customize the alumina ceramic foam filters according to customer specifications.
