Foam Furnace Filters,Ceramic Filter Manufacturers

In recent years, Foam Furnace Filters have been developed as a new type of molten metal filter to reduce casting defects. It plays an important role in the metal casting and casting industry, in which they are used to remove impurities in molten metal to improve the quality and performance. Final product.

Even the smallest nonmetallic impurities in the molten metal may have a destructive effect on the properties and strength of the finished metal. This may result in the failure of the final product to meet the necessary quality standards. Ceramic filters play an important role in removing these impurities and ensuring high quality castings.

Ceramic Foam Filters Material

Our ceramic foam filters have 2 materials to choose from: alumina ceramic foam filter for aluminum and aluminum alloy, zirconia ceramic filter for stainless steel and nickel alloys.

Ceramic foam filter is a phosphate free high alumina based product with high porosity and mechanochemical stability. It has excellent resistance to molten aluminum thermal erosion and corrosion. It can effectively remove inclusions, reduce trapped gas and provide laminar filtration of molten aluminum during laminar flow. The combination of definite tolerance makes it the first choice for molten nonferrous metal filtration.

Ceramic foam filters are widely used in molten aluminum filtration in primary and secondary aluminum foundries. They are also used as filtration media in gas liquid and liquid solid separation engineering.

The ceramic foam filter is equipped with a soft / hard washer to prevent metal bypass. Its size is 40-600mm and the aperture is 10-40ppi. Special sizes are also available.

Application of Foam Furnace Filters

Purification of molten metal liquid
Simplified gating system
Improving metallurgical structure of castings
Reducing slag inclusion in casting
Improve the qualified rate of casting
Reducing reoxidation defects in castings
Reduce the surface defects after casting processing
Advantages of ceramic foam filters
High strength, no loose ceramic particles or powder
Three dimensional connected mesh structure, high porosity
The surface area of slag collection is large, and the internal surface area of filtration is large
Excellent thermal shock resistance
Available in various sizes, shapes and apertures
Particles larger than pore size are captured on top of ceramic foam filters.
The smaller particles are captured by the filter cake produced by the larger particles
Fine particles are trapped in the pores of the filter
