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 is insulating oxide ceramics that are thermally conductive.

Excellent raw materials and advanced production technology ensure quite stable dimensional tolerance of our ceramic foam filters.

SIC Ceramic Foam Filters Production Process

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.

Filtration principle:

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.

These ceramic foam filters are ideal for use in the casting process of ductile iron, layered iron, malleable iron and all other high and low alloy cast-iron types.

Using the unique formula and manufacturing process, SIC ceramic foam filters have the excellent thermal shock, chemical and high temperature resistance up to 1500°C.

As the most advanced filter type with the higher filtration efficiency, It can effectively reduce inclusions and turbulence of molten metal, ensuring purified molten metal goes into the mould cavity with improved flow rates.

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.

Silicon carbide ceramic foam filter is a kind of reticulated structure foundry filter which coated with silicon carbide material.They effectively remove inclusions, reduce entrapped gas in the liquid metal and provide laminar flow, resulting in significantly cleaner filtered metal. Therefore, SiC ceranic filters are often used for the filtration of cast iron and non-ferrous alloys.
