Installation notes
- 1Set into the ladle bottom with matching ramming/bedding mass; ensure concentric nozzle seating
- 2Align with the slide-gate mechanism before securing
- 3Controlled dry-out with the ladle lining; protect carbon-bearing grades from oxidation
- 4Match grade (Al₂O₃-C / Zr-C / Mag-Sp-C) to steel grade and campaign target
