What is a Tundish Covering Agent?

A tundish covering agent is a proprietary mixture, typically consisting of sintered or granular materials, that is applied over molten steel in tundishes during continuous casting. Its core functions are:

  • Minimizing heat loss (thermal insulation efficiency ≥ 94%)
  • Preventing steel oxidation by air exposure
  • Absorbing impurities and floating inclusions
  • Sustaining steel temperature uniformity and nozzle protection

With technological advances, leading tundish covering agent exporters now offer Eco-Friendly Particle Covering Agent that meet diversified global demands.

FAQ: Technical Terminology Explained for Tundish Covering Agent Exporters

1. What is bulk density, and why does it matter for tundish covering agents?
Bulk density (g/cm³) refers to the weight per unit volume, impacting coverage efficiency and reaction rate. A lower bulk density (e.g., 0.39 g/cm³) means more insulation per kilogram and faster, uniform distribution on the steel surface.
2. How does granulation size (e.g., 3-5mm) affect covering agent performance?
Uniform granulation (3-5mm) ensures predictable melting kinetics, smooth spreading, and minimal dust formation — vital for best-in-class tundish covering agent manufacturers.
3. What is slag absorption index?
Slag absorption index quantifies the agent's capacity to incorporate and neutralize non-metallic inclusions during steel casting. A value above 0.85 is considered excellent by industry standards.
4. Which international certifications are significant for tundish covering agent exporters?
Key certifications include ISO 9001 (Quality), ISO 14001 (Environment), REACH/RoHS (EU compliance), and EN 13284 (emissions).
5. How is shelf life or service life assessed?
Shelf life is tested by humidity-aging and heating-regeneration cycles; field service life depends on application but typically exceeds 12 months in dry storage, with no caking thanks to surface conditioning.
6. Can Eco-Friendly Particle Covering Agent be used in non-ferrous metallurgy?
Yes. Its inert formulation and low reaction with molten alloys make it suitable for copper, aluminum, and nickel production — as verified by ASTM-E2X metallurgical compatibility testing.
7. What is the recommended coverage thickness for optimal tundish protection?
Industry best practice prescribes a uniform 22–30mm covering layer, corresponding to a product application rate of 10–12kg/m², ensuring full thermal sealing and impurity scavenging.
