Ceramic Foam Filtering Method, Ceramic Foam Filter 30 PPI

Aluminum foundries adopt the ceramic foam filtering method to produce aluminum billets, aluminum rods, aluminum plates, aluminum wire, and others.

The ceramic foam filtering method used is a two-stage filter box, which is a foam ceramic two-stage filter plate with 30PPi mesh and 40/50PPi mesh. The aluminum liquid needs to be filtered through a first stage before it flows into the front box. The ceramic foam filter plate can effectively block metal and non-metal inclusions and bubbles in the aluminum melt, play a role in purifying the aluminum melt, and provide a basic guarantee for obtaining high-quality cast-rolled blanks.

As the filtering volume of the aluminum liquid increases, the pores of the ceramic foam filter will be blocked by inclusions, which will affect the cleanliness of the aluminum melt after filtration, so the filter plate needs to be replaced in time.

Advantages of Ceramic Foam Filtering Method

Ceramic foam filter has good strength at room temperature and does not drop slag during transportation and operation.
Ceramic foam filter has a certain high temperature strength, thermal shock resistance, and liquid metal erosion resistance.
Ceramic foam filter has good chemical stability and does not react with alloy liquid.
Ceramic foam filter has suitable pore size, good ability to permeate alloy liquid and ability to filter non-metallic inclusions.
Ceramic foam filter has good appearance quality. No deformation, small size deviation, uniform aperture, and no plugging phenomenon.

Ceramic foam filter for aluminum melt filtration outside the furnace is an effective method to improve the cleanliness of molten aluminum. The ceramic filtration process can effectively remove various inclusions in the molten aluminum with a fineness of micrometers, reduce the influence of inclusions on the quality of the cast-rolled blanks, and provide a basic guarantee for obtaining high-quality cast-rolled blanks.

Foundry Ceramic Filters Application: Used for aluminum liquid filtration

● Reduce waste related to inclusions

● Reduce costs related to inclusion defects

● Improve productivity through higher extrusion or rolling speed

● Improve casting flexibility by easily changing alloys
