Alumina Three-Hole Saddle Ring: High-Performance Refractory Support And Heat Storage Element
Alumina Three-Hole Saddle Ring: High-Performance Refractory Support And Heat Storage Element
The Alumina Three-Hole Saddle Ring is a specialized ceramic packing element manufactured from high-purity alumina (Al₂O₃) material through high-pressure forming and high-temperature sintering. Its unique structural design features a cylindrical shape with three parallel through-holes evenly distributed along its axis, significantly increasing specific surface area and porosity while ensuring mechanical strength. With exceptional refractoriness, thermal shock resistance, chemical inertness, and mechanical strength, it is ideal for extreme high-temperature and corrosive environments.
Primary Applications
  • Industrial Furnaces/Kilns: Widely used as a heat storage medium in Regenerative Thermal Oxidizer (RTO) and Regenerative Catalytic Oxidizer (RCO) systems for efficient waste heat recovery
  • Chemical Industry Packing: Used as catalyst supports or corrosion-resistant packing in reaction towers and packed columns within petrochemical and fertilizer production
  • Metallurgical Industry: Used for support, separation, or thermal radiation elements in high-temperature furnace chambers
  • Environmental Protection Equipment: Serves as high-temperature and corrosion-resistant support grids or packing layers in flue gas treatment units
Core Advantages
  • Resists Extreme Temperatures: High softening point allows for long-term, stable operation in environments exceeding 1600°C
  • Excellent Thermal Stability: Three-hole structure facilitates heat transfer and offers good thermal shock resistance
  • Superior Chemical Corrosion Resistance: Strong resistance to acidic and alkaline gases, as well as molten slag
  • High Strength & Wear Resistance: High bulk density and robust structure provide high crush strength and long service life
  • Efficient Heat Storage/Mass Transfer: Porous structure offers vast gas-solid contact area, enhancing efficiency

Installation & Operation Guidelines
  • Before Installation: Ensure the furnace or tower interior is level and clean
  • During Installation: Arrange in regular or staggered random pile pattern to ensure uniform gas distribution
  • During Heat-up: Follow prescribed furnace drying curve to prevent thermal stress damage
  • During Operation: Avoid direct impact from materials and prevent severe temperature fluctuations
After-Sales Service
We provide comprehensive technical consulting and installation guidance services. The product warranty period is 12 months from the date of shipment. In case of quality issues under normal operating conditions, we promise rapid response with solutions including replacement, return, or technical support.
Frequently Asked Questions
Alumina Three-Hole Saddle Ring: High-Performance Refractory Support And Heat Storage Element 0 Alumina Three-Hole Saddle Ring: High-Performance Refractory Support And Heat Storage Element 1
Q: What are the advantages compared to ordinary ceramic Raschig rings?
A: Higher mechanical strength and better thermal shock resistance, making it particularly suitable for demanding high-temperature heat storage and corrosive environments where strength and durability are critical.
Q: How to choose the Al₂O₃ content?
A: The choice depends on the operating temperature and corrosiveness. For higher temperatures and stronger corrosive conditions, grades with 99% or higher purity are recommended.
Q: Can dimensions be customized?
A: Yes. We support custom production based on customer drawings or specific requirements.
