Aluminum Oxide Foam Ceramic

The aluminum oxide foam ceramic filter plate can effectively remove inclusions from micron-sized fines in aluminum water and make aluminum water into stable laminar flow, which is good for punching. It has a unique mullite corundum structure, good mechanical strength, and chemical stability, superior aluminum water scouring performance, and strict control of pore size and through-hole rate can achieve stable filtration effect. There is a sealed ceramic fiber liner around the foam ceramic filter plate, which helps to seal the filter in the CFF filter box and ensure no metal flow.

The Aluminum Oxide Foam Ceramic Filter product is mainly used in the purification process of aluminum and aluminum alloy production, as well as various gas-solid, liquid-solid separation media, catalyst carrier, burner and sound-absorbing environmental protection fields.

Aluminum Oxide Foam Ceramic Filter Advantages

  • High dimensional accuracy, high mechanical strength.
  • Stable chemical composition, anti-corrosion of liquid aluminum and its alloy.
  • No phosphorus, environment-friendly, purifying liquid aluminum.
  • Improving aluminum quality, reducing defects, reducing defective rate, reducing cost, increasing production efficiency, and easy to use.
  • The size ranges from 40mm to 600mm to meet different aluminum water flow rates.

Foam Ceramic Filter Application

Foam Ceramic Filter is suitable for the production of high-quality aluminum and aluminum alloy. Through physical adsorption and chemical action, ceramic foam filter can effectively remove all kinds of oxidation inclusions produced in the aluminum smelting process, and improve the casting quality.

The filter plate should be heated close to the temperature of liquid aluminum before use. If the impurity content in aluminum water is too high, it should be adjusted by multi-stage filtration or reducing the amount of pass-through.

In order to meet the requirements of the quality of aluminum castings, the use of alumina foam ceramic filter plates is becoming more and more important. It is also widely used in common sand casting such as wet mold casting and permanent mold casting, such as automobile aluminum parts casting.

The filtration process is mainly based on the following considerations: on the one hand, the filtration makes the aluminum liquid flow orderly and relatively calm, on the other hand, the solid slag in the liquid metal is effectively removed, and the casting quality is rapidly improved.
