Performance of Silicon Carbide Beams, Square Beams, and Square Tubes Silicon carbide beams, square beams, and square tubes exhibit excellent strength and material properties, performing well under load-bearing conditions up to 1350°C in tunnel kilns, roller hearth kilns, natural gas furnaces, electric wire furnaces, and silicon carbide rod electric furnaces. Main Features: This product offers excellent thermal stability, high strength, and strong high-temperature load-bearing capacity. Utilizing the latest technology and high-temperature oxidation treatment, an oxide film forms on the surface, enhancing oxidation resistance, preventing slag shedding, and ensuring no bending or deformation during long-term use. Main Applications: This product is particularly suitable for load-bearing structures in tunnel kilns, shuttle kilns, double-layer roller hearth kilns, and other industrial furnaces. 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).
