Attention please: 200x200x50mm 10ppi Silicon Carbide ceramic foam filters are exported to USA client!

SIC ceramic foam filter is a newly developed high-performance solution for molten metal filtration, which can effectively reduce casting defects and improving product quality.

Main features of Hebei CangChen SIC filters

1. Silicon carbide ceramic foam filter adopts Japan 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. 

2. SIC ceramic foam filter produced by our company adopts advanced laser cutting technology, which can meet the requirements of manual modeling and mechanized production line with higher efficiency, and ensure the quality standard requirements of casting factory productization.

3. SIC ceramic foam filter has the characteristics of high strength, good thermal stability, large specific surface area and high dimensional accuracy. 

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

Filters Applications

1. 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.

2. Effectively remove oxidized inclusions and other non-metallic inclusions by blocking and capturing adsorption of molten copper or molten iron using three-dimensional structure.

3. 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.

4. Also suitable for copper, bronze, brass and other copper alloys, reduce the turbulence of copper liquid and purify the molten copper liquid.

5. 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.

6. Also play 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.

Advantages of our filters

● Large surface area.

● Excellent thermal shock resistance.

● High strength without loosing ceramic particles or powder.

● Various materials, sizes, shapes and pore density are available.

● Three dimensional connected mesh structure and high porosity.

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. 

Using the unique formula and manufacturing process, sic ceramic foam filters have the excellent thermal shock, chemical and high temperature resistance up to 1530°C.
