Silicon Carbide is among the hardest of ceramics,
and retains hardness and strength at elevated
temperatures, which translates into among the best wear
resistance. Additionally, SiC has a high thermal
conductivity, especially in the CVD (chemical vapor
deposition) grade, which aids in thermal shock resistance. It
is also half the weight of steel.Based on this, SiC is often
specified for seal faces and high performance pump parts. Applications of SiC Its physical hardness makes it ideal to be used in abrasive
machining processes like grinding, honing, sand blasting and water
jet cutting. On top of that, it has also been used in the manufacture
of ceramic brake discs for sports cars, bulletproof vests,
seal ring material for pump shaft sealing where it frequently runs
at high speed in contact with a similar silicon carbide seal. | Furnace Type | Max Working pressure:58bar/98bar | | RDE-3312-N | RDE-4412-N | RDE-5512-N | RDE-5518-N | | Usable Space (W*H*L) | 300*300*1200mm | 400*400*1200mm | 500*500*1200mm | 500*500*1800mm | | Max.Charge Load | 300kg | 500kg | 1200kg | 1500kg | | Power Rating | 320KVA | 320KVA | 430KVA | 600KVA | | Heating Zone | 2/3 Zones | 3 Zones | 3 Zones | 3 /4 Zones | | Cooling time | ≤5h | ≤6h | ≤7h | ≤8h | Empty furnace, cooling from sintering temperature 2100℃ to 100℃.
