High Quality Ceramic Refractory Balls Containing 65.75.85% Alumina for Sulphur Furnace

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Temperature Insulation: Designed to withstand extreme temperatures in sulphur furnaces and industrial kilns, providing efficient thermal insulation to maintain optimal operational conditions.
  • Structural Support: Spherical ceramic balls made of alumina ceramic (65.75.85% alumina content) ensure durability and stability in high-pressure, corrosive environments, supporting furnace fixtures and structural integrity.

Key features

  • 1. Material Technology: Corrosion-Resistant Alumina Ceramic

    • With a high alumina content of 65.75.85% Al₂O₃, these refractory balls offer superior corrosion resistance and thermal stability in harsh furnace environments. Compared to standard ceramic materials, this composition ensures prolonged durability under extreme temperatures and chemical exposure*.

  • 2. Performance Parameters: Enhanced Thermal Insulation

    • With optimized insulation properties, these balls maintain consistent high-temperature resistance (up to 1700°C), outperforming conventional refractory materials by reducing heat loss by ~15-20% in industrial furnaces*.

  • 3. Scenario Solutions: Tailored for Sulphur Furnace Applications

    • Designed specifically for sulphur furnaces, these balls provide reliable structural support and heat retention in corrosive, high-pressure environments. Their spherical shape ensures uniform heat distribution, ideal for continuous industrial operations*.

  • 4. Certification Standards: EU Compliance Assurance

    • Certified to EU standard (EU) 2015/863, these balls meet stringent safety and environmental regulations, ensuring compatibility with export and industrial standards in regulated markets*.

  • 5. Interactive Design: Uniform Spherical Shape for Efficiency

    • The precise spherical design minimizes friction and maximizes space utilization in furnace fixtures, enabling smoother operation compared to irregularly shaped refractory materials*.
