Molten Aluminum Filter for Casting

Molten Aluminum Filter for Casting

The passage of metal in molten form may be an important step in the formation of the final casting. This can be solved by installing a molten aluminum filter for casting. Because there are no impurities and unnecessary bubbles are formed, the correct design can be provided.

During the charging process, molten metal processing and liquid metal processing operations, impurities are introduced into the melt. Even when the primary ingot is melted, non-metallic impurities such as hydrogen and aluminum oxide are introduced.

Sources of foreign inclusions include refractory particles, usually from degradation of the furnace wall and/or transfer ladle. The sources of primary inclusions produced by grain refinement products include oxide films, fluxes, alloying elements and intermetallic compounds. Although the inclusions present in the furnace vary from foundry to foundry, their removal is critical to maintaining the cleanliness of the molten metal.

The foundry industry requires the use of pure quality molten metal in order to use it for metal castings. Filtration can be done with the help of ceramic foam filters to remove impurities and other ingredients. The alumina ceramic foam filter for casting can remove inclusions, reduce trapped gas, provide laminar flow when filtering molten aluminum.

Molten Metal Filter Plate

The ceramic foam filter for casting has the ability to resist thermal shock to maintain the entire filtration process. The excellent quality of the cast filter ensures stronger resistance to heated molten metal.

The compressive strength of the filter enables it to withstand the higher pressure applied during the filtration process.

Since the foundry filters used in various metal filtration processes are different, the foundry that needs them can find a suitable filter for their needs.

Ceramic Foam Filter Size

660x660x50 (26″)
584x584x50 (23″)
508x508x50 (20″)
432x432x50 (17″)
381x381x50 (15″)
305x305x50 (12″)

Pore size of ceramic foam filter (PPI): 10/20/30/40/50/60

The 30ppi 40ppi cast filter is the most commonly used ceramic foam filter in the aluminum casting industry.
Ordinary aluminum castings usually use 10-40ppi ceramic filter plates.
Aviation and high-quality aluminum materials usually use 30-60ppi ceramic filter plates.
