Application Scenarios & Technical Advantages: tundish covering agent manufacturers

  • Metallurgical Steel Casting: Ensures superior heat insulation and prevents steel surface oxidation, reducing energy consumption up to 9% (as per World Steel Association 2023).
  • Petrochemical Sector: Provides anti-corrosive protection on process water tundishes, extending service life by 30% versus traditional agents.
  • Infrastructure & Utilities: Used in continuous casting tundish for water distribution and waste treatment, with less than 1.5% water absorption (CERTIFIED: EN 993-15).

Key advantages over legacy materials:

  • Energy Saving: Significantly lower thermal conductivity provides optimal insulation, minimizing heat loss.
  • Extended Life Cycle: Non-reactive and low-dust—outlasts fused-slag and magnesia alternatives by 28% (Field tests, 2023).
  • Environmental Compliance: All raw materials meet RoHS/ISO 14001 sustainability directives for global applications.
  • Adaptable Particle Range: CNC screening ensures grade consistency across diverse tundish designs.
