Equipment scope
- Coating layer and working layer
- Dry-material body
- Opening and drainage point
- Filling point
- Touch-up and local repair positions
Hot-zone logic
The tundish is a daily operating vessel, not a static refractory item. Its lining must form cleanly, release on schedule, open reliably, and return to service without turning every sequence into a fresh troubleshooting exercise. That is why the tundish route has to be built as an operating package rather than as separate consumable purchases.
Dominant failure pressures
- Inconsistent working-layer formation
- Slow turnaround and difficult strip-out
- Free-opening instability during casting sequences
- Sequence-to-sequence variation caused by fragmented sourcing
- Local deviations that must be corrected without breaking daily rhythm
Material combination
- Magnesia coating or Al2O3 coating according to the tundish working route
- Environmental-protection dry material for working-layer formation and strip-out control
- Drainage sand for opening reliability
- Ladle filler / filling material for stable filling and discharge behavior
- Gunning mix or local repair support for fast turnaround correction
Commercial value
This solution gives continuous-casting buyers something they can standardize and audit: operating consistency. It reduces the hidden cost of fragmented consumable buying, improves sequence stability, and makes repeat orders more meaningful because they correspond to a controlled tundish package rather than to disconnected line items.
