Exceptional Durability and Chemical Resistance
SSiC rollers exhibit outstanding resistance to wear, corrosion, and oxidation, even at elevated temperatures and in aggressive acidic or alkaline settings. This makes them indispensable for industrial sectors requiring robust, reliable solutions, including ceramics, powder metallurgy, and high-temperature kilns.
Reliable Performance in Extreme Conditions
Engineered for continuous operation up to 1550C, these rollers retain excellent mechanical properties, such as high bending strength (400-550 MPa) and fracture toughness. Their low thermal expansion and exceptional dimensional stability ensure uniform results in temperature-intensive applications.
Advanced Manufacturing and Material Purity
Manufactured using pressureless sintering, SSiC rollers achieve a dense, fine-grained structure with minimal free silicon and carbon. This results in superior hardness (Mohs 9-9.5), minimal water absorption (0.1%), and high electrical resistivity, ensuring consistent quality and purity for critical applications.
FAQ's of Pressurelss Sintered SiC (SSiC) Rollers:
Q: How are pressureless sintered SiC (SSiC) rollers manufactured?
A: SSiC rollers are produced using pressureless sintering, a process where high-purity silicon carbide powder is compacted into roller shapes and then sintered at elevated temperatures without applied pressure. This method yields a dense, fine-grained material with excellent mechanical and chemical properties.Q: What benefits do SSiC rollers offer in high-temperature applications?
A: SSiC rollers deliver exceptional thermal stability, low thermal expansion (4.0-4.2 106/K), and outstanding wear and oxidation resistance, making them ideal for continuous use in environments up to 1550C, such as roller kilns and furnace components.Q: Where are SSiC rollers typically used?
A: These rollers are commonly used in roller hearth kilns for ceramics, tile manufacturing, powder metallurgy, glass production, and high-temperature processing in the electronics and chemical industries, where durability and chemical inertness are vital.Q: What size ranges and shapes are available for SSiC rollers?
A: SSiC rollers are available in diameters ranging from 40 to 250 mm and lengths up to 4500 mm. They feature a cylindrical, solid shape and are offered in a fine, dense surface finish tailored to specific industrial requirements.Q: How do SSiC rollers resist corrosion and wear in harsh environments?
A: With over 98% silicon carbide content and minimal porosity (<0.1%), SSiC rollers exhibit excellent chemical resistance against acids and alkalis, along with superior wear resistance, ensuring long service life even in aggressive or abrasive conditions.Q: When should SSiC rollers be chosen over other refractory materials?
A: SSiC rollers are preferable when processes demand high strength, low thermal expansion, and resistance to corrosion, oxidation, and thermal shock at continuous temperatures exceeding 1500C, outperforming many conventional refractory ceramics.Q: What are the key advantages of SSiC rollers compared to other kiln roller materials?
A: Compared to aluminium oxide or other ceramics, SSiC rollers provide higher mechanical strength, better thermal conductivity (>35 W/mK at 1000C), superior dimensional stability, and a longer operational lifetime under extreme industrial conditions.Tell us about your requirement
