Eficasia LLC supplies specialized mineral sands used as ladle and EBT filler materials in steelmaking operations. Our products are selected to ensure consistent flow behavior, thermal stability, and reliable free-opening performance in demanding steel production environments

Chromite (Cr₂O₃-based) and Zircon (ZrO₂-based) sands are widely used as ladle filler materials due to their high thermal resistance and stable behavior under steelmaking conditions. The quality and consistency of the filler sand directly impact ladle free-opening performance

Key Characteristics

  • High refractoriness and thermal stability
  • Controlled granulometry for consistent flow
  • Non-sintering behavior at operating temperatures

Operational Benefits

  • Improves ladle free-opening rate
  • Reduces tapping delays
  • Enhances operational safety
  • Supports stable casting operations

Olivine-based filler sand is used in EBT (Eccentric Bottom Tapping) systems in electric arc furnaces, providing reliable flow behavior and high free-opening ratios during tapping operation

Key Characteristics

  • High MgO content (up to ~50–51%)
  • Sinter-free behavior
  • High melting point
  • Stable particle size distribution

Operational Benefits

  • Facilitates easy EBT tap hole opening
  • Achieves high free-opening ratios
  • Improves molten metal fluidity
  • Helps reduce operating costs and stabilize operations

Our team can provide detailed product information and guidance to help you select the right filler sand for your operation.
