Installation notes
- 1Joint with carbon-bonded or high-alumina mortar; keep joints tight (1–2 mm)
- 2Protect carbon-containing brick from oxidation during dry-out, limit air exposure above 400°C
- 3Use coke-breeze or controlled reducing dry-out where specified
- 4Match grade to ladle zone: barrel (Al₂O₃-C), slag line (Al₂O₃-ZrO₂-C), impact pad (high-strength)
