Molten Aluminum Casting Filter

Molten Aluminum Casting Filter

Since the ceramic foam filter has excellent resistance to molten aluminum corrosion, it can effectively remove inclusions, reduce residual gas and provide laminar flow in the molten aluminum casting process. Molten aluminum casting filter is suitable for improving the quality of aluminum alloy and other non-ferrous alloy castings. It can improve metallurgical structure and enhance mechanical properties to convert turbulent flow into laminar flow.

Ceramic foam filters for foundry are mainly used to filter aluminum and aluminum alloys in foundries and foundries. The molten aluminum filtered through the ceramic foam filter is significantly cleaner. Clean aluminum can produce higher-quality castings in industries such as aerospace, automotive, electronics, and more, all of which help increase profits.

The alumina ceramic foam filter is based on a carrier with a solid network structure and organic foam cells. Used to filter and purify molten aluminum alloy.

Production Process of Alumina Ceramic Cast Filter

Put the carrier into the thixotropic alumina slurry, and use a square centering automatic extrusion process to make the slurry uniformly deposit on the foam skeleton of the carrier. After drying and curing, it is calcined to form a carrier, which finally becomes the final product. Sintering is performed at a high temperature of 1180°C.

Advantages of Molten Aluminum Casting Filter

  • The ceramic casting filter adopts the principle of adsorption, which can effectively remove large impurities in molten aluminum and effectively adsorb small impurities.
  • No debris falls off, effectively reducing the pollution of molten aluminum and reducing waste related to inclusions.
  • Excellent thermal shock resistance improves the corrosion resistance of molten metal.
  • Improve surface appearance and performance, purify molten aluminum.
  • Reduce related production costs.
