Installation notes

  1. 1Handle with care, lower crushing strength than dense bricks
  2. 2Use lightweight insulating mortar or colloidal silica bonded mortar
  3. 3Never expose directly to liquid metal or slag, always use with working lining
  4. 4Dry-out schedule: ambient to 200°C at 10°C/hr, hold 4 hrs, then proceed slowly
