Product Description
L-board is a special refractory or structural material with an L-shaped cross section, which is widely used in high-temperature industrial equipment where corner support, sealing or connection is required. Its name comes from its cross-sectional shape similar to the letter "L" (right-angle structure). It is usually made of high-aluminum, corundum, silicon carbide or silicon refractory materials (the specific material is selected according to the working conditions), and is produced by extrusion molding, sintering or casting processes. Some products may add fiber reinforcement materials to improve thermal shock resistance.
1. Structural adaptability: The L-shaped design can seamlessly fit the corners or edges of the equipment, simplifying installation and enhancing the overall structural stability.
2. High temperature resistance: Depending on the material, the temperature resistance range can reach 1200°C (silicon) to 1800°C (corundum).
3. Mechanical stress resistance: The right-angle structure provides high compressive and flexural strength, suitable for areas subject to equipment expansion stress or material impact.
4. Sealing performance: When used in connection parts, it can effectively reduce the leakage of high-temperature gas or melt, and needs to be used with refractory mud or sealant.
5. Thermal shock resistance: Some materials (such as silicon carbide or fiber reinforced) can withstand frequent temperature changes and reduce the risk of cracking.
1. Metallurgical industry: blast furnace, converter lining corner reinforcement; ladle, tundish corner sealing and insulation layer.
2. Glass industry: glass melting furnace breast wall, pool wall corner connection; annealing furnace support frame.
3. Ceramics and building materials: tunnel kiln, roller kiln kiln edge protection; high temperature sintering furnace door sealing structure.
4. Chemical equipment: reactor lining corner anti-corrosion layer; high temperature pipeline flange connection support.
