Customized SIC Ceramic Foam Filter For Iron And Steel Casting Filtration

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

Mainly used for filtering and purifying nodular cast iron, gray cast iron, aluminum, copper and other alloy metal liquid filtration.

Our 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, Simply called SIC ceramic foam filters.

Applications of SIC filters:

SIC Ceramic foam filters 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.

How to choose suitable SIC filter?

1. Confirm the exact dimensions:

● A rectangle or a square: length, width and thickness

● Round: diameter and thickness

● Special-shaped: up length, bottom length, height and thickness

2. Confirm ppi:

● No matter what shapes and dimensions, ppi must be confirmed according to your application, if not, it will influence filtration effect.

SIC Ceramic Foam Filter 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.
