Performance of Silicon Carbide Beams, Square Beams, and Square Tubes Silicon carbide beams, square beams, and square tubes exhibit excellent strength and material properties, demonstrating outstanding load-bearing capacity in tunnel kilns, roller kilns, natural gas kilns, electric wire furnaces, and silicon carbide rod electric kilns at temperatures up to 1350°C. Main Features: This product offers excellent thermal stability, high strength, and substantial high-temperature load-bearing capacity. Utilizing the latest technology and high-temperature oxidation treatment, an oxide film forms on the surface, providing exceptional oxidation resistance, no slag shedding, and long-term use without bending or deformation. Main Applications: This product is particularly suitable for use as load-bearing structural frames in tunnel kilns, shuttle kilns, double-layer roller kilns, and other industrial kilns. It is an ideal kiln furniture for industries such as high-voltage electrical ceramics, sanitary ceramics, glass-ceramics, and refractory materials, with a lifespan several times longer than that of other materials (below 1380°C).
