Thermal Shock Resistance Reaction-Sintered SiC Beam

Custom High-Strength Reaction-Sintered Silicon Carbide (SiC) Square Beams
Kiln Structural Support for Continuous Operation up to 1380°C
Dimensions: 30 mm * 40 mm * 900 mm | Wall Thickness: 5 mm
Upgrade your high-temperature kiln with our custom-engineered Reaction-Sintered Silicon Carbide (R-SiC) square beams. Designed for demanding thermal and mechanical environments, these beams provide superior structural support in shuttle, tunnel, and roller hearth kilns. Offering a maximum service temperature of 1380°C, exceptional load capacity, and excellent thermal shock resistance, they are the optimal, long-lasting alternative to heavier conventional materials. Request a quote for custom sizes tailored to your specific kiln geometry.

Key Features & Benefits
  • High-Temperature Structural Integrity - Maintains strength and dimensional stability under continuous operation at temperatures up to 1380°C.
  • Superior Mechanical Strength - High flexural strength at both ambient and elevated temperatures ensures reliable, long-term performance under load.
  • Excellent Thermal Shock Resistance - Withstands rapid heating and cooling cycles without damage, reducing downtime and maintenance.
  • Lightweight & Energy Efficient - Lower thermal mass compared to traditional supports enables faster kiln cycling and significant energy savings.
  • Extended Service Life - Outperforms metal and many ceramic supports in high-temperature environments, reducing replacement frequency and total cost of ownership.
  • Full Customization - Available in tailored dimensions, lengths, and with precision end-finishing to integrate seamlessly into your kiln design.

Load-Bearing Capacity for Kiln Design
Engineered with a bending strength of 250 MPa and a 5x safety factor for reliable operation. The table provides reference values for a 1-meter span.
Load Capacity Reference Table (1-meter span)
Cross-section (mm) Wall Thickness (mm) Max. Concentrated Load (kg) Max. Total Distributed Load (kg)
30 * 30 5 74 147
30 * 40 5 117 235
40 * 40 5 149 298
50 * 50 6 283 567
50 * 60 6 374 748
60 * 60 7 481 962
Calculation Method
For a beam of length L (in meters):
  • Max. Concentrated Load = (Table Value for Concentrated Load) * L
  • Max. Total Distributed Load = (Table Value for Distributed Load) * L
Example: A 50*50 mm beam, 2 meters long, can support a total distributed load of 567 kg * 2 = 1,134 kg.

Typical Applications
These high-strength SiC beams are engineered as critical load-bearing components in:
  • Shuttle Kilns
  • Tunnel Kilns
  • Roller Hearth Kilns
  • Other high-temperature industrial furnace superstructures
