Silicon carbide ceramic foam filters are essential tools in casting ductile iron, grey iron, and other nonferrous metals. They help decrease reject rates while improving quality in the final product.
As opposed to phosphate binders, this filter features superior high-temperature strength while being free from pollution to alloys. Plus it is lightweight and durable!
High-Purity
SIC ceramic foam filters are constructed from high-grade raw materials and advanced production technology, guaranteeing consistent product quality. Ideal for iron and ferroalloy molten metal filtration, they help improve castings by reducing inclusions, turbulence, trapped gas formation, laminar flow production as well as reduced rework rate waste and slag for lower costs of castings production.
Our SIC ceramic foam filter is constructed of non-reactive material that can withstand temperatures up to 1500degC. The foam structure protects molten metal from chemical, acid and oxide attack while offering thermal shock resistance as well as being suitable for cast iron applications.
The present invention utilizes aqueous binders such as carboxymethyl cellulose and polyvinyl alcohol instead of traditional phosphate binder which produces pernicious gases during sintering and pollutes the environment, to create an eco-friendly ceramic foam ceramic filter which is free of toxic substances, with excellent high temperature stability in iron and copper melt, to prevent oxide inclusions in molten alloy, while its filtration, purification and adsorption capacities are excellent. Furthermore, preheating can be avoided during use while renewing capability allows it to perform contrast tests repeatedly unlike its traditional predecessor.
High-Temperature Resistance
Silicon carbide ceramic foam filters are specially engineered to withstand high-temperature impacts and chemical corrosion, making them the perfect solution for applications involving liquid metals. Their porous structure enables them to absorb large volumes of metal without degrading or melting over time – ideal for drinking water treatment, metallurgy and sewage treatment applications.
Silicon carbide ceramic is often manufactured through mixing it with binder and pore-forming agent in solvent, creating a slurry. This slurry is then impregnated onto carrier materials such as soft combustible organic plastic foam. After drying and shaping, this ceramic foam filter blank undergoes sintering; becoming an extremely durable and efficient filter suitable for various applications.
Foamed ceramic filters developed recently are distinguished by their excellent high-temperature stability in molten iron solutions, no alloy contamination and great adsorption efficiency for removing oxide- and flux-associated impurities from molten metal. The filter can effectively filter impurities from castings made of ductile cast iron, grey iron and malleable cast iron as well as malleable cast bronze castings; additionally it can decrease pouring gate turbulence while decreasing inclusion defects significantly, leading to higher-quality castings, less scrap and ultimately greater bottom-line profits than ever before!
Lightweight
Silicon carbide ceramic foam is an incredibly lightweight material with numerous applications in various industries. Thanks to its superior thermal conductivity and temperature resistance, silicon carbide ceramic foam makes an excellent solution for purifying metals and alloys in foundries, steelmaking facilities and automotive manufacturers.
Ceramic foams are highly resistant to chemical attack, making them perfect for use in harsh environments. Their non-reactivity with molten metals makes them great at filtering corrosive materials from filtering processes, while their impressive mechanical strength make it suitable for high pressure applications.
This filter is widely used for filtering Ductile Iron, Grey Iron, Vermicular Casting Iron and some Iron Alloys. It effectively eliminates impurities to maintain steady metal filling in mold. Furthermore, this filter reduces air flow impact during casting and pin hole and sand hole defects to boost production weight.

Durable
Silicon carbide ceramic foam filters are essential components for industrial processes that require the filtration of molten metal. By eliminating impurities to produce superior end products, they help aerospace, automotive, and foundry industries meet quality standards more effectively. They’re durable enough to handle heat, chemical corrosion, mechanical stress and multiple reuses saving both money and waste.
Ceramic foam filters feature an open porous structure with multiple pores of different sizes, which results in high permeability for filtering out various impurities from molten metal. Their mechanical strength also prevents them from breaking during handling and use.
Cleanliness is easy and can be reused after each wash cycle, as the unit does not interact with acids and alkalis and will not pollute filtered metal liquid, helping reduce operational costs while increasing quality in molten metal production.
Ceramic foam filters come in all sorts of shapes and sizes to meet all types of casting setups, from gray iron and ductile iron casting to copper alloy casting and help reduce turbulence during metal casting processes. Round or square specifications are both available.
