Reaction-bonded silicon carbide square beams are widely used in the load-bearing structures of tunnel kilns, shuttle kilns, double-layer roller hearth kilns, and other industrial furnaces. These square beams exhibit excellent high-temperature load-bearing capacity and good dimensional stability, making them suitable for load-bearing requirements in high-temperature environments. Applications in high-temperature environments: Due to their outstanding high-temperature resistance, reaction-bonded silicon carbide square beams perform exceptionally well in high-temperature settings, making them suitable for various high-temperature kilns such as roller hearth kilns, tunnel kilns, and rotary kilns. These beams do not fracture suddenly at high temperatures, have a long service life, and do not contaminate the products. 1. Silicon Carbide Beams: Silicon carbide beams are oxidation-resistant, high-strength, and maintain their shape under long-term use. They serve as load-bearing supports for shuttle kilns, double-layer kilns, and other industrial furnaces. The products are widely used in various industrial kilns, desulfurization equipment, large boilers, and other mechanical equipment, as well as in industries such as ceramics, machinery, metallurgy, electronics, chemical engineering, petroleum, and steel. Features of the beams: High strength, high hardness, high wear resistance, corrosion resistance, excellent oxidation resistance, and thermal shock resistance. Compared to recrystallized silicon carbide and silicon nitride-bonded silicon carbide, reaction-bonded silicon carbide beams demonstrate superior long-term performance. The flexural strength of reaction-bonded silicon carbide is more than twice that of recrystallized silicon carbide and approximately 50% higher than that of silicon nitride-bonded silicon carbide. Silicon carbide square beam products operate at temperatures up to 1380°C, with all technical parameters remaining unchanged. They are widely used in industries such as desulfurization in absorption towers, kiln refractories, and electronic machinery. The product features high strength, high hardness, high-temperature resistance, wear resistance, corrosion resistance, oxidation resistance, resistance to rapid cooling and heating, excellent thermal shock resistance, good thermal conductivity, and high thermal efficiency. 2. Square Beams: Also known as reaction-bonded silicon carbide square beams; suitable for the load-bearing structures of tunnel kilns, shuttle kilns, double-layer roller hearth kilns, and other industrial furnaces. This product offers high load-bearing capacity at elevated temperatures, does not bend or deform under long-term use, and has a service life several times longer than that of materials made from other substances. It is an ideal kiln furniture for industries such as sanitary ceramics and electroceramics. The product exhibits excellent high-temperature flexural strength, thermal shock resistance, and oxidation resistance, maintaining its shape under prolonged use while significantly reducing energy consumption without increasing the weight of the kiln car. The flexural strength of reaction-bonded silicon carbide square beams is calculated based on 250 MPa, with a safety factor of 5 for load-bearing; the load-bearing capacity for a length of 1 meter is determined. If the product length is L, the load-bearing capacity can be calculated using the following formulas: concentrated force = surface value / L, uniformly distributed force resultant = surface value * 1 / L. This load-bearing capacity is applicable at temperatures up to 1380 degrees Celsius.
