Overview of High Strength Foam Ceramic Filter Alumina Porous Ceramic Discs

High Strength Foam Ceramic Filter Alumina Porous Ceramic Discs is advanced porous structures made from high-purity aluminum oxide (Al₂O₃). Designed for molten metal filtration, they effectively remove slag, oxides, and non-metallic inclusions, ensuring cleaner and higher-quality castings in aluminum, iron, steel, and other metal alloys.

Key Features of High Strength Foam Ceramic Filter Alumina Porous Ceramic Discs

High-Temperature Resistance – Stable up to 1700°C, ideal for molten metal applications.

Uniform Porosity (10-100 PPI) – Customizable pore sizes for efficient impurity removal.

Excellent Thermal Shock Resistance – Withstands rapid temperature changes without cracking.

High Mechanical Strength – Durable under extreme casting conditions.

Chemical Inertness – Resists corrosion from molten metals and fluxes.

Specification of High Strength Foam Ceramic Filter Alumina Porous Ceramic Discs

These alumina foam ceramic filters are tough discs created cleaning liquified metal. They get rid of unwanted bits from aluminum, copper, and comparable alloys. The major product is high-purity alumina oxide. This provides the filter excellent stamina and warm resistance.

The filters come in typical dimensions like 50mm, 100mm, 200mm, and 300mm sizes. Density typically ranges from 20mm to 50mm. You can obtain different shapes too, like circles and squares. The pore dimension is important. Usual choices are 10 PPI, 20 PPI, and 30 PPI. This number tells you approximately the number of pores fit in one linear inch. Reduced PPI indicates bigger holes. Greater PPI indicates smaller sized openings. You choose the PPI based upon just how clean you need the steel.

Porosity is very high, commonly 80% to 90%. This indicates the majority of the filter is open room. It enables a great deal of metal to move via quick. However it still catches slag and oxides properly. The open cell structure is three-dimensional and interconnected. Contaminations obtain captured deep inside the filter, not just externally.

These discs take care of severe warmth well. They work fine up to 1700 ° C. They also handle unexpected temperature level changes without cracking. This is crucial when hot metal hits them. The product is inert. It will not respond with many liquified steels. You get constant performance batch after batch. Compressive strength is high. The filter won’t collapse under the steel circulation pressure. It stays steady during casting. Installation is easy. Area the filter in eviction system or mold. It traps oxides and inclusions as the metal streams. The outcome is cleaner, stronger castings with fewer problems. Factories depend on them for high quality metal parts.

Applications of High Strength Foam Ceramic Filter Alumina Porous Ceramic Discs

Molten steel often contains littles dirt, gas bubbles, and various other unwanted things. These contaminations damage the final cast metal components. Alumina porous ceramic discs fix this trouble. They are solid foam blocks made from unique ceramic material. These discs have many little linked openings throughout them.

You put these discs straight in the course of the flowing molten metal. The liquid metal puts with the disc’s open structure. The small openings imitate a super-fine net. They literally capture the solid littles dirt and slag suspended in the steel. The tidy steel moves via conveniently right into the mold.

This filtering system action is important. It stops damaging contaminations from getting into your casting. Cleanser metal means stronger finished parts. You obtain less splits and breaks. The surface finish of castings looks much better too. There are fewer flaws needing expensive repairs or triggering part failing.

High strength foam ceramic filters work well for lots of metals. Factories use them widely for light weight aluminum and aluminum alloys. They are also really reliable for filtering copper, brass, bronze, and cast iron. You locate them in automobile parts manufacturing. They are made use of for aerospace components. They are essential for making high-grade pump real estates and shutoff bodies. Lots of critical industrial spreadings depend on this technology.

The alumina product takes care of extreme heat without damaging down. It withstands the extreme chemical strike from liquified metal. These discs stay solid under the hefty flow and pressure of pouring. They supply trustworthy filtering batch after set. Utilizing them brings about extra consistent, higher quality steel castings.

5 FAQs of High Strength Foam Ceramic Filter Alumina Porous Ceramic Discs

What are these ceramic filters made of?
They use high purity alumina. This material gives them strength and heat resistance. Alumina handles extreme conditions well.

How hot can these filters get?
They withstand very high temperatures. The maximum is about 1700°C (3092°F). This makes them safe for filtering hot metal like steel or iron. They won’t melt or break down.

Do they slow down the metal flow?
Flow rate depends on the PPI number. PPI means pores per inch. A lower PPI number means bigger pores and faster flow. A higher PPI means smaller pores and slower flow. You choose the PPI based on your metal type and cleanliness needs. The filters control flow effectively.

How do I install them in the mold?
Installation is straightforward. You cut the disc to fit your gating system. Place it where the metal enters the mold cavity. Secure it firmly. This stops impurities getting into your casting. It ensures clean metal fills the mold.

Can I reuse them after casting?
Yes, you can usually reuse them. Knock out the solidified metal carefully. Clean the filter thoroughly. Remove all residue. Inspect for cracks or damage. Undamaged filters can often be used multiple times. This saves money.
