Ceramic Foam Filter Aluminum Filtration

Ceramic Foam Filter Aluminum Filtration

Ceramic foam filter aluminum alloy filtration adopts a three-dimensional network structure and uses organic foam with interconnected pores as a carrier to penetrate the thixotropic alumina material slurry. The full-automatic extrusion process with square correction of the center distance is adopted to make the slurry evenly spread on the foam skeleton of the carrier. After drying and curing, it is baked at a high temperature of 1180°C. Installed in the CFF filter box, used to filter impurities in the aluminum alloy liquid.

AdTech, the manufacturer of ceramic foam filters, can provide ceramic foam filters of 20-80 PPI. The ceramic foam filter is made of continuous mesh foam plastic soaked in mud and baked at high temperatures. Therefore, the raw materials used to make the filter plate are divided into foam and mud.

The foam material used to produce the ceramic foam filter should have sufficient elasticity and strength to ensure recovery and resistance to breakage when immersed in the mud. In the submerged stage, there are no congenital defects such as local depressions and cracks. The parameter that usually describes foam specifications is PPI (pores per inch), which is the number of pores per inch.

The ceramic foam filter aluminum alloy filtration is filtrating by adsorption principle. It can effectively remove large inclusions in aluminum liquid and effectively adsorb small-size inclusions. It is not effective to reduce the pollution of aluminum slag. Good thermal shock resistance and improved corrosion resistance to molten metal. Automatic production line, accurate size, more suitable for CFF filter box.

The use of an alumina ceramic foam filter is important for molten aluminum alloy filtration. In addition to the actual production requirements for the quality of aluminum products, the flow rate of aluminum in the washing tank, the total amount of filtration, the cleanliness of the aluminum itself, and the production cost must also be considered. Choosing high-specification foam ceramic filter plates will increase production costs and reduce production efficiency.
