Cast aluminum filters are mainly used to remove inclusions generated between the refining system and the die table. The ability of a ceramic foam filter to capture these inclusions is critical to maintaining a clean ingot during metal solidification. As a result, the quality and productivity of downstream processes such as forging, extrusion and rolling are guaranteed.
Aluminium foundry places the foam ceramic filter in the CFF unit, and the aluminium and aluminium alloys are fed into the hot top casting platform through a launder.
Cast aluminum filters advantages
1. The filter has excellent resistance to the erosion and corrosion of molten aluminum, and can effectively remove inclusions.
2. Reduce residual gas, provide laminar flow, and the filtered metal is significantly cleaner.
3. Cleaner metal produces higher quality castings.
4. Less waste and less inclusions are beneficial to increase profits.
As the largest aluminum melting and foundry in South America, Brazil Aluminium has a wealth of experience.
In the smelting process, aluminum is exposed to the atmosphere in the furnace in a molten or semi-molten state, which is easily oxidized, easily reacts with water vapor and absorbs hydrogen, and easily forms various forms of non-metallic slag.
On the other hand, part of the waste in the ingredient charge contained some non-aluminium impurities during the recycling process.
Since the wastes come from process wastes, wastes from various processes in the factory and wastes outside the factory, the routes are different, the components are complex, and the quality is poor.
These impurities are easy to cause bubbles and inclusions in the slab, which seriously affect the purity of the metal melt, which in turn affects the processability, mechanical properties, corrosion resistance and appearance quality of the product.
Our ceramic foam filter uses good portiforium foam and high purity ceramic as raw material, can remove non-metal solid mixture from molten aluminium and aluminium alloy effectively in your aluminium casting industry.
Using the right High-Temperature Materials will affect your productivity in a positive way!
AdTech specially designed ceramic foam filter are made of the basic raw material Aluminium Oxide. They are manufactured with porosities varying from 10 to 60 pores per inch (PPI). Also, combo sets are made in 20-30 PPI and other selections are possible. Different sizes and custom-made filters are manufactured according to specifications.
