Ceramic Foam Filter
Silicon carbide ceramic foam filter adopts Japan 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 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, copper, bronze, brass and other copper alloys, and other alloy metal liquid 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 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.
SIC ceramic foam filter has the characteristics of high strength, good thermal stability, large specific surface area and high dimensional accuracy.
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.
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 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.
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
