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