Product Description

Ceramic Foam Filter Introduction:
Foam Ceramic are mainly used for filtration of aluminium and aluminium alloys in foundries and cast houses. With their excellent thermal shock resistance and corrosion resistance from molten aluminum, they can effectively eliminate inclusions, reduce trapped gas and provide laminar flow, and then the filtered metal is significantly cleaner. Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit. Ceramic foam filter is a kind of effective molten metal filter. It's three-dimensional connected mesh structure and high porosity has many advantages, for example, large surface area of slags collection, large inner surface area of filtering, small flow resistance, good filtering effect, etc.

Size available:
7", 9", 12", 15", 17", 20", and 23", with porosities from PPI 10 to PPI 60(PPI ie pores per inch).
Other special sizes could be produced on request.

Advantages:
*Eliminates turbulence in the metal stream, Smoothes out metal flow, avoiding sprays, splatter and backset. Improve fluidity, castability, machinability, yield
*Remove a much greater fraction of fine particulate, Reduce rejects and rework
*Low-pressure loss
*Provides consistent flow rate and capacity
*Various sizes, shapes and pore sizes are available

Functions:
*Decontaminate the melting metal liquid
*Simplified gating system
*Improve the metallurgical structure of the castings
*Reduce imparities of the castings
*Improve casting quality rate
*Reduce casting internal re-oxidation defects
*Reduce the surface defects after machining of the castings

Classification
*Alumina Foam Filter
*Silicon Carbide Ceramic Foam Filter
*Zirconia Ceramic Foam Filter
