Introduction of Nitride Bonded Silicon Carbide Roller:

Applications of Nitride bonded silicon carbide rollers include but are not limited to high temperature sintering belts of roller kilns such as domestic ceramics, ‌ sanitary ceramics, ‌ building ceramics, ‌ magnetic materials, ‌ and bearing structural frames of tunnel kilns, ‌ shuttle kilns, ‌ double roller kilns and other industrial kilns. ‌

Advantages of Silicon Nitride Bonded Silicon Carbide Roller:

Our Silicon Nitride Bonded Silicon Carbide Rollers are required to undergo laser testing for straightness before leaving the factory, and we retain the test data for each Nsic Roller. Each product will be tested by a standard flexural strength testing machine, and will be packaged and shipped to customers only after passing the test.

Our Nsic Rollers have high temperature resistance, ‌ cold and hot resistance, ‌ high temperature creep resistance, ‌ high bending strength, ‌ thermal shock resistance, ‌ strong oxidation resistance, ‌ no slag and extremely strong wear resistance and corrosion resistance. ‌Its long-term use of non-fracture, ‌ no bending characteristics, ‌ and the advantages of high temperature bearing capacity, ‌ makes the service life of silicon carbide roller rod far beyond the traditional alumina ceramic rod, ‌ reached more than 10 times. ‌

‌Applications of NSic Rollers in High-Temperature Industries‌

NSic Rollers have emerged as critical components in high-temperature industrial processes due to their exceptional thermal and mechanical properties. Combining the oxidation resistance of silicon carbide with the fracture toughness of silicon nitride, NSic Rollers demonstrate superior performance in extreme environments.

Primarily applied in continuous kilns and furnaces, NSic Rollers serve as load-bearing elements in ceramic tile production lines, metal heat treatment systems, and advanced glass tempering processes. NSic Rollers' low thermal expansion coefficient (3.5–4.5×10⁻⁶/°C) and high thermal conductivity (15–25 W/m·K) enable stable operation at temperatures exceeding 1,400°C, significantly outperforming traditional alumina-based rollers. In the steel industry, NSic Rollers facilitate scale-free heat treatment of alloy sheets by maintaining structural integrity in corrosive atmospheres containing CO and sulfur compounds.

The unique interlocking microstructure of silicon nitride matrices reinforced with SiC grains provides remarkable resistance to thermal shock, a critical requirement in rapid cooling applications. This property, combined with a flexural strength exceeding 450 MPa, minimizes roller deformation during repeated thermal cycling. Recent adoption in solar panel manufacturing highlights their growing importance in renewable energy sectors, where they ensure precise silicon wafer positioning in diffusion furnaces. With service lifetimes 3–5 times longer than conventional materials, NSic Rollers reduce maintenance costs while improving production efficiency across multiple high-tech industries.
