How do we produce SIC ceramic foam filters?

Hebei Cangchen company adopts:

1. German imported polyurethane foam sponge as the carrier,

2. the slurry which mainly contains silicon carbide is extruded into the foam sponge,

3. and then extrude slurry,

4. the remaining slurry coated around the foam fiber is dring, roasting and sintering at high temperature,

5. polyurethane is decomposed by heat,

6. the foam shaped ceramic products are left, namely, silicon carbide foam ceramic filter.

Main Functions:

● 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. 

● SIC ceramic foam filter mainly used for filtering and purifying nodular cast iron, gray cast iron, aluminum, copper and other alloy metal liquid filtration. 

● SIC ceramic foam filter mainly used for nodular cast iron, gray cast iron, aluminum.

Export To Spain for casting filtration:

SIC ceramic foam filter mainly used for nodular cast iron, gray cast iron, aluminum with foam sponge three-dimensional mesh interworking structure.

● Purify metal molten liquid

● Simplify pouring system

● Improve the casting metallographic structure

● Improve casting qualification rate

● Reduce inclusions in castings

● Reduce the reoxidation defects of castings internal

● Reduce surface defects of castings after machining
