A basic oxygen furnace relined before its refractory has actually reached end of life is wasted campaign length, and the three levers that most directly extend how many heats a BOF lining survives, lining pattern design, gunning strategy, and slag-splashing tactics, are too often managed as separate operational habits rather than one coordinated campaign strategy. A vessel running toward 4,000 heats on a well-optimized campaign and one relined at 2,800 heats on an unoptimized one can be running the exact same refractory brick, with the difference entirely explained by how the lining was protected heat by heat. Optimize your own BOF campaign strategy around actual wear data.
The Same Brick Can Last Thousands More Heats
iFactory AI coordinates lining pattern design, gunning strategy, and slag-splashing tactics to extend BOF refractory campaigns toward 4,000 heats.
Three Levers, Managed Together
Lining pattern design sets the foundation a campaign starts from, gunning strategy protects specific wear zones heat by heat, and slag-splashing tactics build a protective layer over the lining between heats, and when these three are managed as separate operational habits rather than one coordinated strategy, the campaign tends to end wherever the weakest-managed lever allows, not where the refractory itself was actually capable of reaching.
Lining Pattern Design
Brick selection and zone-specific thickness matched to known high-wear areas.
Gunning Strategy
Targeted gunning material applied to protect specific wear zones between heats.
Slag-Splashing Tactics
Controlled slag coating timed and applied to maximize protective layer retention.

What Each Tactic Protects
Each tactic addresses a specific wear mechanism, and coordinating them means matching the right tactic to the right wear zone at the right time.
| Tactic | Wear Mechanism Addressed | Timing |
|---|---|---|
| Lining pattern design | Baseline wear resistance across all zones | Set at reline, informs the whole campaign |
| Gunning strategy | Localized erosion in known high-wear zones | Applied between heats as wear develops |
| Slag-splashing | General surface protection across the vessel | Applied after most heats as standard practice |
From Wear Data to Coordinated Tactics
Reading wear data continuously is what allows the three tactics to be coordinated rather than applied on a fixed routine regardless of actual condition.
Rolling Out Campaign Optimization
iFactory AI connects to existing wear monitoring and operational logging to coordinate the three tactics around real-time vessel condition.
Expert Review
The gap between a well-optimized and poorly optimized BOF campaign is usually explained less by any single tactic and more by consistency, since a plant that coordinates gunning and slag-splashing reliably on every heat tends to outperform one with a technically better lining design but inconsistent day-to-day execution.
Frequently Asked Questions
Does this require new wear monitoring sensors on the vessel?
Where wear monitoring already exists, it connects directly; where it does not, a recommended monitoring approach is scoped as part of the rollout. Support can confirm what your vessel currently has.
How are gunning recommendations targeted to specific zones?
Zone-level wear tracking identifies which specific areas are wearing fastest, and gunning recommendations are generated for those zones rather than applied uniformly across the vessel.
Can this work with our existing lining pattern design process?
Yes, the system works alongside your existing lining design process, using actual wear outcomes to inform future pattern decisions rather than replacing that engineering judgment. Discuss integration with your design process on a call.
How close to 4,000 heats is realistic for our specific operation?
The realistic target depends on your steel grades, operating practices, and starting lining design, and is estimated from your own historical campaign data rather than a fixed industry number.
Does this integrate with our existing production scheduling?
Yes, campaign progress and projected relining windows can feed into your existing production planning systems. Ask support about scheduling integration.
