SiC Square Beams Brief
SiC Square Beams Industrial Kiln Load-Bearing Component
A Silicon Carbide (SiC) Beam is a high-performance, key load-bearing component for industrial kilns, manufactured using the reaction-bonded silicon carbide process. It is specifically designed for extreme high-temperature environments. It is primarily used in industrial kilns such as tunnel kilns, shuttle kilns, and double-layer roller hearth kilns, serving as the core structural framework for supporting kiln furniture and products. Its core value lies in its ability to operate long-term under high temperatures of up to 1380°C while maintaining exceptional dimensional stability and structural strength, significantly enhancing kiln operation efficiency, energy savings, and service life. It is an indispensable high-end kiln furniture in industries such as sanitary ceramics, electroceramics, and refractories.
SiC Square Beams Key Features and Advantages
- High Straightness Standard: The straightness of the working surface of the silicon carbide (SiC) square beam is ≤1‰. Each beam undergoes strict straightness testing before leaving the factory.
- Rigorous Strength Testing: Every SiC square beam is tested with a 70 MPa standard bending strength testing machine to ensure its reliability and safety.
- High-Performance Lightweight Design: SiC square beams offer a truly high-performance lightweight kiln beam and column design. The exceptional strength of the material allows for a 50% reduction in the cross-section compared to traditional recrystallized silicon carbide (R-SiC) beams without compromising load capacity, and it enables operation at higher temperatures.
- Excellent Chemical Resistance: They possess outstanding chemical resistance, allowing them to operate for extended periods in highly corrosive and ionic environments, resulting in a longer service life.
- Strong Oxidation Resistance: SiC beams exhibit strong oxidation resistance, ensuring stable long-term operation even in oxidizing atmospheres and contributing to a longer lifespan.
SiC Square Beams Applications
Silicon Carbide Beams have key applications in multiple high-temperature industrial sectors due to their unique advantages:
- Sanitary and Building Ceramics Industry: It is the ideal load-bearing kiln furniture in tunnel kilns and shuttle kilns for sanitary ware (e.g., toilets, washbasins), building ceramics, and daily-use ceramics, used for supporting and loading green bodies for firing.
- Electroceramics and Refractories Industry: Widely used in the high-temperature sintering processes of high-voltage electroceramic insulators, glass-ceramics, and refractory products, acting as the load-bearing structural frame within the kiln.
- Other Industrial Fields: Its applications also extend to wear-resistant linings for steel plant quenching furnaces, flue gas desulfurization and dust removal equipment in power plants, large boilers, and some high-tech military equipment.

SiC Square Beams Q&A
Q1: What is a silicon carbide (SiC) beam used for?
A1: It is primarily used as a high-temperature load-bearing component in industrial kilns (like tunnel kilns and shuttle kilns) to support and carry kiln furniture and products during firing processes, especially in sanitary ceramics and electroceramics industries.
Q2: Why choose silicon carbide for kiln beams instead of traditional materials?
A2: Silicon carbide is chosen for its exceptional high-temperature strength, thermal stability (low thermal expansion), oxidation resistance, and long service life, which allow it to operate at temperatures up to 1380°C without bending or deforming, significantly outperforming many traditional materials.
