Product Description

 

Product Description

The ceramic foam filter is the third generation of filter material after fiberglass mesh, honeycomb ceramic filter. With its three-dimensional structure, it has excellent filtering functions of the screen, filtering, residuum collection, and adsorption in filtering molten metal liquid. It has good chemical stability and does not react with alloy liquid, effectively removing the inclusion in the metal liquid to improve the purity of the molten metal. It can make casting surfaces smooth, increase strength, reduce the rejection rate, and reduce energy consumption, improve labor productivity, reduce costs. The ceramic foam filter is not only applied for metal filtering in high temperatures but high-temperature gas treatment, carrier of catalyzer, solid heat exchanger, and special filling for the chemical industry. 

Ceramic Foam Filter Features:
Mechanical block: remove large non-metallic inclusions.
Filtering effect: filter small non-metallic inclusions.
Deep adherence: adhere to little inclusions.
Reduce turbulence, provide laminar flow, and avoid whirlpools.
Trap gas that enters the mold cavity, relaxes impact and decreases drop sand.
Effectively enhance qualification rate.
Improve the metallurgical structure of metal products
Enhance mechanical properties of metal products
Simplify gating system

SEFU ceramic foam filters are available in three materials:
Silicon carbide ceramic foam filter, used for grey iron, ductile iron, copper, bronze, brass, and investment casting;
Alumina ceramic foam filter, used for aluminum and aluminum alloys casting;
Zirconia ceramic foam filter, used for carbon steel, and stainless steel casting.
