Ceramic Foam Filter
Silicon carbide ceramic foam filter adopts German imported polyurethane foam sponge as the carrier, the slurry which mainly contains silicon carbide slurry is extruded into the foam sponge, and then extrude slurry, the remaining slurry coated around the foam fiber during by drying, roasting and sintering at high temperature, polyurethane thermal decomposition, leaving the foam like ceramic products, namely, silicon carbide foam ceramic filter.
SIC ceramic foam filter mainly used for filtering and purifying nodular cast iron, gray cast iron, aluminum, copper and other alloy metal liquid filtration with 1530℃
Parameter
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.
SIC ceramic foam filter has the characteristics of high strength, good thermal stability, large specific surface area and high dimensional accuracy.
Functions:
1. Purify metal molten liquid
2. Simplify pouring system
3. Improve the casting metallographic structure
4. Reduce inclusions in castings
5. Reduce the reoxidation defects of castings internal
6. Reduce surface defects of castings after machining
7. Improve casting qualification rate

Silicon carbide strength and resistance to high temperature impact force and chemical corrosion, use temperature 1530°C. They are suitable for the casting of all copper alloys and cast iron.
It 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.
Application:
Filtration of molten steel and alloy
Large scale iron casting
All copper alloys and cast iron
