Product Description
Alumina Ceramic Foam Filter for Aluminum Casting
Alumina ceramic foam filters are characterized by the existence of a chemical bond. The low density and construction of the ceramic frame allow for the filter to reach minimal dimension deviations during the production process. Alumina ceramic foam filter has the advantages of high porosity, high mechanical strength, stable chemical property, strong corrosion-resistant, high adsorption rate, excellent filtering functions, and thermal shock resistance. It is mainly used for the purification process of aluminum, aluminum alloy, and other nonferrous alloy production, and can also be used as a gas-solid, liquid-solid separation medium, catalyst carrier, burner, and sound-absorbing and environmental protection fields.
Product Functions
Decontaminate the melting metal liquid
Simplified gating system
Improve the metallurgical structure of the castings
Reduce casting internal re-oxidation defects of the castings
Reduce surface defects after machining of the castings.
Effectively remove and absorb large or small impurities in molten aluminum.
Improve the surface quality product performance and microstructure effectiveness.
Handling and Use:
Alumina Ceramic foam filters are fragile and should be handled accordingly. Take a filter out of the package and carefully remove possible ceramic particles by hand or blow them off with pressure air. It is recommended to handle foundry filters without gloves.
By no means try to adapt the filter (cutting or sanding). Its shape and dimensions must correspond with the space in the shell mold or ceramic funnel. For this purpose filters can be protected with a sealing gasket of heat-resistant fibre material. If the gating system does not have a space for filter placement, the filter can be produced with a draft to fit better the conical shape of the funnel.
When choosing the size, shape, dimensions, and porosity of a filter, you should keep the generally applicable rules and principles into account the required size, shape, porosity, and position of the filter.

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.
