Prehanged permenant slag coating on cooling stave


  • Prefabricated block, casted on the cooling stave, instead of fixed brick
  • Directly casted on the metal cooling stave
  • New type of prefabricated cooling block is combined with the cooling water pipe to replace the metal cooling stave


  • High fracture resistance (50 ~ 80MPa), high toughness (high fracture I compression ratio)
  • High thermal conductivity and easy hanging slag
  • The self-regeneration capacity of the precasted layer is expected to solve the problem of slag peeling and realize permanent stability of the slag coating protection
