Roller kiln lithium-ion battery cathode material Sisic roller magnetic material
Product Description:
Featuring high temperature tolerance,high flexural strength, good oxidation and wear resistance, sisic ceramic rollers can be used for a long term without fracture or bend.
The rollers are widely applicable in roller kilns for domestic ceramics, sanitary ceramics, building ceramics, and magnetic materials.
This is reaction bonded (silicon infiltraded) silicon carbide, being formed zero porosity by filling up open porosity with silicon metal (si).
Because of it's zero porosity characteristic, thermal conductivity is more than twice of Oxide Bonded SiC's, bending strength is more than 5 times higher comparing to Oxide Bonded SiC.
SiSiC's sepecial feature is its ability to maintain high strength from room temperature up to 1,350C. Also it has very high oxidation resistance, chemical resistance and wear resistance.
Used as beam, roller, radiant tube burner and burner nozzle etc.
Application:
It can be used as a bearing ball, roller, ball seat, tooling, new ceramic cutting tools, piston pump, sealing material in the machinery industry;
It can be used to produce three times air valve plate and preheater inner tube in the cement industry,;
It can be used as wear and corrosion resistant components, such as ball valve, pump body, combustion carburetor and filter in the chemical industry.
It can be made for metal material processing of mould and die making, such as extubation, mandrel, extrusion, dial wire mould, roll, conveying roller, heating body fixture, thermal couple casing pipe, metal heat processing support, crucible, liquid aluminum tube, aluminum coated liner in metallurgical industry.
It can be used for armored vehicles, aircraft belly, bullet proof clothing, rocket exhaust nozzle and other high temperature work in aerospace industry
