Product DescriptionPremium Corundum Mullite L-Boards for Industrial Refractory NeedsL-board is a specialized refractory material with an L-shaped cross-section, ideal for high-temp industrial equipment needing corner support, sealing, or connection. Named for its L-like shape.SpecificationKey Features & Advantages1. Structural adaptability: The L-shaped design seamlessly fits equipment corners, simplifying installation and boosting stability.2. High temperature resistance: Material-dependent temperature resistance ranges from 1200°C (silicon) to 1800°C (corundum).3. Mechanical stress resistance: Right-angle structure offers high compressive and flexural strength, ideal for expansion stress areas.4. Sealing performance: Effective in reducing high-temp gas or melt leakage, used with refractory mud or sealant.5. Thermal shock resistance: Materials like silicon carbide can endure frequent temperature shifts, minimizing cracking risks.Applications1. Metallurgical industry: Blast furnace, converter lining corner reinforcement; ladle, tundish sealing and insulation.2. Glass industry: Glass melting furnace breast wall, pool wall corner; annealing furnace support frame.3. Ceramics and building materials: Tunnel kiln, roller kiln edge protection; high-temp sintering furnace door sealing structure.4. Chemical equipment: Reactor lining corner anti-corrosion; high-temp pipeline flange connection support.Technical Specifications(Custom configurations available upon request.)PropertiesCorundumMulliteCorundumAl2O3(%)70-90≥90Al2O3+ SiO2(%)>97>97Fe2O3(%)<0.5<0.5RefractorinessUnderLoad(℃)≥1700≥1700Bulk Density (g/cm3)2.65-3.02.85-3.2Apparent Porosity (%)13-2013-20Normal Temperature Compressive Strength (Mpa)≥70≥70ThermalShockReslatanceGoodGoodWhy Choose Us?Certified Quality: ISO-compliant production with rigorous testing for top-grade refractory ceramics.Custom Solutions: Custom crucibles for specialized uses, like weakly alkaline melts.Global Expertise: Trusted by high-temp material experts across Europe, Asia, and North America.Company ProfileShandong Mingte Ceramic Materials Co., Ltd.Shandong Mingte Ceramic Materials Co., Ltd., based in the Development Zone of Mingji Town, Zouping City, Shandong Province, China, was founded in 2013 and covers 42,000 square meters.
