Silicon carbide beams are made using silicon carbide as the main material. They are characterized by high strength, high hardness, high wear resistance, corrosion resistance, good oxidation resistance, good thermal shock resistance, high-temperature resistance, and no deformation during long-term use. They serve as load-bearing supports for shuttle kilns, double-layer kilns, and other industrial kilns. Products are widely used in various industrial kilns, desulfurization equipment, large boilers, and other mechanical equipment, as well as in the ceramics, machinery, metallurgy, electronics, chemical, petroleum, and steel industries.
