Product Description
Alumina Ceramic Foam Filter Plate for Aluminum Casting
Alumina ceramic foam filters mainly 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:
- Effectively eliminate the bulk of molten aluminum inclusions.
- Removed small size of several microns inclusions in the normal process of molten aluminum. At the same time, as ceramic foam filters reduce the small inclusions, effectively reduce the number of nuclei in the liquid aluminum, and shorten the solidifying time, organizations are refined.
- Reduce the hydrogen content in liquid aluminum. Hydrogen atoms can be adsorbed in oxide inclusions, oxide inclusions can be the core of gas generation. It also filtered gas when removing the inclusion.
- By adsorption, It can remove the harmful elements in molten aluminum (Na K).
Alumina Ceramic Foam Filter Selection
In general, choosing alumina ceramic foam filters should take into account the requirements of finished product quality, the flow capacity of the molten aluminum tank, the amount of the total filtration of molten aluminum, and aluminum liquid cleanliness and other factors.
The choice of alumina ceramic foam filter is as follows, it is just for customer reference.

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 to flow 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 began 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.
After-Sales services
1. After the goods are shipped, assist the customer to follow up on the goods.
2. Understand the customer's use plan, and do a good job of guidance.
3. Collect customer feedback.
4. Assist in handling customer complaints and making customers satisfied.
If it is damaged during transportation, it will be replenished according to the situation. If the product is found to have quality problems during use, our factory will replace or return the product after both parties confirm that it is a filter element problem.
