Specifications of Alumina Ceramic Foam Filter Plate for Filtration of Molten Aluminum

Alumina ceramic foam filter layers clean molten aluminum. They remove undesirable things before casting. This boosts metal high quality. The filter is made from high-purity aluminum oxide. This product withstands severe heat extremely well. It stands up to deterioration from liquified light weight aluminum also.

The filter structure resembles foam. It has several interconnected holes forming a network. This network traps solid particles and oxides suspended in the metal. Catching takes place throughout the entire filter body. The pore dimension is measured in PPI (pores per inch). Common PPI choices are 10, 20, 30, 40, 50, and 60. Higher PPI indicates smaller holes. Smaller openings catch finer contaminations. Picking the appropriate PPI depends upon the needed metal cleanliness degree.

Standard filter shapes are rounded or square. Common sizes consist of 305x305mm, 330x330mm, 406x406mm, and 508x508mm. Thickness usually varies from 25mm to 50mm. Custom-made dimensions are feasible. The filter product deals with temperature levels over 1700 ° C easily. This is much above normal liquified aluminum spreading temperature levels around 700 ° C.

You place the filter plate inside an unique metal box called a filter box. This box sits in the launder system between the heater and the casting mold and mildew. Molten aluminum streams with the filter box. The filter captures dangerous particles as the steel passes through its open pores. Tidy metal leaves the other side. This filtration action considerably minimizes defects in last cast products. It gets rid of inclusions like oxides and other non-metallic bits. This leads to stronger, much more trustworthy light weight aluminum parts. The filter plate itself is non reusable after one usage. It comes to be saturated with trapped product.

Applications of Alumina Ceramic Foam Filter Plate for Filtration of Molten Aluminum

Alumina ceramic foam filter layers tidy molten aluminum extremely well. They capture impurities prior to spreading. Dirty steel makes bad spreadings. These filters take care of that issue. They resemble sponges made from hard ceramic. The open-cell foam framework traps little fragments. Alumina ceramic manages severe warmth. It remains strong in molten aluminum. This material resists chemical attack. It will not melt or break down conveniently. The filter plates fit inside standard filter boxes. Workers put them in the steel flow path. Molten light weight aluminum puts through the filter. Solid bits get stuck inside the foam. Tidy metal spurts the other side. This process eliminates oxides, carbides, and other junk. Cleanser steel means far better final products. Castings end up being stronger. They look smoother. Problems like openings or splits occur less often. Factories see less rejected components. Manufacturing expenses go down. Quality rises. Heater linings last much longer as well. Less filthy metal removes the lining material. Filter plates are simple to use. Employees handle them safely. They are available in different sizes and pore degrees. You choose based on your steel circulation and cleanliness needs. Utilizing them enhances metal yield. Much less great steel obtains thrown out with the slag. These filters are crucial for quality aluminum casting. They work for numerous alloys. They deal with various spreading techniques.

5 FAQs of Alumina Ceramic Foam Filter Plate for Filtration of Molten Aluminum

What is an alumina ceramic foam filter plate?
It’s a porous ceramic block made from aluminum oxide. You place it in molten aluminum flow paths. The foam structure catches impurities. This makes cleaner castings.

How does this filter work?
Molten aluminum flows through the filter’s tiny pores. Solid impurities get trapped inside the foam. Clean metal passes through. The high porosity allows good metal flow rates. It captures very small particles effectively.

Why choose alumina ceramic over other filters?
Alumina ceramic handles extreme heat well. It won’t crack in molten aluminum. The material resists chemical attack from the metal. Its open cell structure offers high filtration efficiency. It provides consistent results batch after batch.

How do you use this filter correctly?
Preheat the filter slowly before use. This prevents thermal shock. Place it securely in the filter box or launder system. Ensure molten metal flows entirely through the filter plate. Never let metal bypass it. Handle the filter carefully before heating. It’s brittle when cold.

Can you reuse the filter plate?
No, these filters are single-use only. After filtration, the filter holds trapped impurities. Trying to clean it damages the fragile foam structure. Discard the used filter plate safely after each casting cycle. It’s designed for one job.
