Silicon carbide are suitable for the casting of all copper alloys and cast iron because of its high strength, resistance to high temperature impact force and chemical corrosion and operating temperature 1530°C. 

SIC Ceramic foam filters can significantly improve the quality of cast iron parts and reduce the rejection rate. They can also be used in continuous casting and rolling processes and can be manufactured to different sizes and thicknesses depending on the runner and pouring weight.

Features of SIC ceramic foam filter:

● As a new type of inorganic non-metallic filtration material for internal structure, silicon carbide ceramic foam filter has the advantages of light weight, high strength, high temperature resistance, corrosion resistance, simple regeneration, long service life, and good filtration adsorption.

● Silicon carbide ceramic foam filter can be compacted by sanctuary under normal pressure. It can be compacted without high pressure and inert atmosphere, reducing the production cost of the enterprise.

● Adding a proper sintering assistant will reduce the sintering temperature of SIC ceramic foam filter. When sintering, it can reduce the oxidation of silicon carbide on the surface of foam and improve the overall performance of foam ceramics.

● Silicon carbide ceramic foam filter is not easily corroded by acid -base when filtering, and does not pollute the filtered metal liquid. It can be reused after use, which does not reduce filtration efficiency and greatly reduce corporate costs.

SIC Ceramic Foam Filters Production Workshop

Silicon carbide ceramic foam filter adopts German imported polyurethane foam sponge as the carrier, the slurry which mainly contains silicon carbide is extruded into the foam sponge, and then extrude slurry, the remaining slurry coated around the foam fiber is dring, roasting and sintering at high temperature, polyurethane is decomposed by heat, foam shaped ceramic products are left, namely, silicon carbide foam ceramic filter.

SIC ceramic foam filter with foam sponge three-dimensional mesh interworking structure can make the metal liquid reflect the rectification, mechanical screening, filter cake, adsorption filtration mechanism to effectively improve the purity of metal liquid, reduce scrap rate, reduce machining losses so as to improve production efficiency and reduce production costs.

Functions:

● SIC Ceramic foam filters can significantly improve the quality of cast iron parts and reduce the rejection rate. They can also be used in continuous casting and rolling processes and can be manufactured to different sizes and thicknesses depending on the runner and pouring weight.

● It can effectively remove oxidized inclusions and other non-metallic inclusions by blocking and capturing adsorption of molten copper or molten iron using three-dimensional structure. No matter gray iron, ductile iron, shaft body, cylinder block or complex large pieces, hardware parts after filtering, the quality will be very stable and satisfactory results.

● It is also suitable for copper, bronze, brass and other copper alloys, reduce the turbulence of copper liquid and purify the molten copper liquid. What is especially valuable is that the life of copper castings purified by filtration is significantly prolonged in high requirements or harsh environment such as Marine turbine and chemical parts, and it also has good effect on the cast copper parts with surface polishing requirements.

● It also plays an important role in the traditional copper industry, electrical and electronic copper industry and continuous casting and rolling technology. Since copper and its alloys, including zinc alloys, have greater specific gravity and produce greater thermal shock during pouring, the use of silicon carbide foam ceramic filters in the copper casting process generally has strict size requirements.

Quality Inspection & strength test

Three most important key points that make our quality always best are:

● The most advanced testing equipment and technology are adopted today in Hebei Cangchen to ensure the consistant filters quality. 

● There is a quality inspection team with rich experience and technology to keep best quality in our quality control department.

● Thanks to many years of product export and feedback information from domestic and foreign customers, we have accumulated considerable experience and expertise in quality control and improvement.

For now, Hebei Cangchen is a professional manufacturer with ISO certificate and our Silicon Carbide (SIC) ceramic foam filters have been passed RoHS And Reach test and certified.

All dimensions can be customized according to clients' requirements!
