The single-hole ceramic beam is a high-performance ceramic structural component specifically designed for high-temperature industrial kilns, chemical processing equipment, and packing support systems. Manufactured primarily from alumina (Al₂O₃) or silicon carbide (SiC), its unique single-hole structure optimizes gas flow while maintaining exceptional mechanical strength and corrosion resistance, making it ideal for extreme high-temperature, high-pressure, and corrosive environments.

Applications

• Industrial Kilns: Load-bearing supports for tunnel kilns and roller hearth kilns (withstands up to 1600°C)

• Chemical Processing: Packing support structures for sulfuric acid towers and absorption towers (acid-resistant)

• Semiconductor Manufacturing: Load-bearing components for high-temperature heat treatment equipment

• Environmental Engineering: Wear-resistant support components for desulfurization and dust removal systems

Advantages

✅ High-Temperature Resistance (Alumina: 1600°C, SiC: 1800°C)
✅ Exceptional Mechanical Strength (Flexural strength ≥250MPa, SiC version superior)
✅ Chemical Corrosion Resistance (Resists acids, alkalis, and oxidizing media)
✅ Lightweight Design (Density 2.3-3.2g/cm³, reduces kiln load)
✅ Extended Service Life (5-10 times more durable than metal beams)
