AI Optimization Recommendations Feed for Steel Plant Process and Energy Levers

By James C on May 4, 2026

ai-optimization-recommendations-feed

A modern blast furnace generates several thousand tags a minute — chemistry, temperatures, pressures, raceway data, burden profiles, hearth thermocouples, stove cycle status. The hard part is not collecting it. The hard part is deciding which two or three signals matter right now, and what to do about them. The iFactory AI Optimization Recommendations Feed sits on top of every model running on your on-site appliance — the digital twin, the SPC quality predictor, the hearth wear model, the burden CFD — and turns their output into a short, ranked feed of operational levers a shift operator can read in thirty seconds. Every card carries a severity band, a confidence percentage, the model badge, and the change it suggests in the units the operator already works in. Decision support, not autopilot — operators approve, defer, or reject, and every action is logged. Walk through the live feed with us on a live webinar on May 13, 2026 — register here.

How To Read The Feed

Three Severity Bands. One Way Of Reading Each One.

A recommendation is more than a number. The severity band tells the operator how urgently to look at it; the confidence tells them how much weight to put on it; the model badge tells them where it came from. Together those three pieces are enough to triage the feed without opening every card.

HIGH
Act this shift

Process drift that, if left, lands inside a quality-hold zone or a safety threshold within hours. Operator action is expected unless explicitly deferred with a reason.

Examples: hearth thermocouple cluster trending against safety band · top-gas CO₂ utilisation collapsing · raceway pressure imbalance.
MEDIUM
Plan within the day

An optimisation lever the model can defend with material expected savings or risk reduction over the next 8–24 hours. Operator owns the timing — the model owns the rationale.

Examples: PCI rate adjustment for coke saving · burden distribution rebalance · hot blast temperature step.
LOW
Worth knowing, no rush

A directional suggestion the model has identified but with effect that's small, slow-moving, or low-confidence. Often surfaced for shift-handover discussion rather than immediate action.

Examples: pellet ratio drift versus target · slag basicity nudge · stove cycle phase optimisation.
The Feed Today

Five Active Recommendations · Ranked, Badged, Scored

An illustrative snapshot of what the feed looks like at the start of a 14:00 shift on a 5,000 m³ blast furnace. Numbers and severities are representative — your feed is built against your furnace, your historian, and your operating envelope. We can walk through your data in a discovery session.


HIGH HEARTH PROTECTION 14:02
Rotate active tap-hole · move from TH-2 to TH-4
Hearth thermocouple cluster on the south-east wall has been trending +0.4 °C/hr for the last 9 hours, consistent with raceway-driven wall washing on the TH-2 side. Rotation to TH-4 is the established lever for redistributing the hot zone. Expected to flatten the trend within 2 shifts.
CHANGETH-2 to TH-4

MODELREFRACTORY CNN + INVERSE HT

MEDIUM COKE SAVING · PCI 13:48
Increase PCI rate by +8 kg/THM
Coal flow stability is good, raceway adiabatic flame temperature is 2,180 °C with headroom, and oxygen enrichment supports a step up. At a 0.9 coke-replacement ratio, +8 kg/THM PCI saves approximately 7 kg/THM of coke. Below the maximum operable PCI band for this blast condition — well inside permeability margin.
CHANGE+8 kg/THM
CONFIDENCE76%
MODELXGBOOST · COKE-RATE

MEDIUM BURDEN DISTRIBUTION 13:30
Adjust ore/coke ratio to 2.6 at the wall ring
Radar profilometry shows the central coke ring slightly thinner than the charging matrix specifies, while the wall ring is ore-heavy. CFD-DEM simulation suggests an O/C trim toward 2.6 at the wall improves gas-flow centring and lifts top-gas CO₂ utilisation. Expected effect over 4–6 charges.

MEDIUM HOT BLAST TEMPERATURE 13:14
Step hot blast temperature up to 1,200 °C
Stove dome temperatures are running 18 °C above target with adequate burn-through margin. Stepping HBT from 1,178 °C to 1,200 °C reduces specific reductant demand and is well inside the 900–1,300 °C envelope of the stove design. Energy model attributes a small but durable saving over a 24-hour window.

LOW PELLET RATIO 12:55
Lift pellet share of ferrous burden toward 22%
Burden has been running pellet-light at 17% versus the 22% target set last month, after a sinter plant availability event normalised. Pellet uniformity tends to lift permeability and gas utilisation; the model attributes a modest fuel-rate benefit over many shifts. Worth raising at handover, no rush.

The Model Stack

Every Recommendation Carries A Badge — So Operators Know Where It Came From

There is no single model behind the feed. Different parts of the furnace have different physics, different timescales, and different best-fit techniques. Each recommendation surfaces the badge of the model that produced it, so the operator and the metallurgist can drill into the reasoning rather than treating the feed as a black box.

XGBOOST
Coke Rate & Burden Mix

Gradient-boosted regressors trained on your historian. Strong on tabular relationships between chemistry, blast conditions, burden composition, and fuel rate. Used for PCI, pellet ratio, and slag-basicity recommendations.

SHAP-based attribution · explainable per recommendation
CFD-DEM
Burden Distribution & Gas Flow

3D fluid + particle simulation of the shaft and bosh. Reads radar profilometer data to reconstruct burden layers, predicts gas-flow centring and pressure-drop response. Slow but rigorous — used for burden distribution recommendations.

OpenFOAM-derived kernel · refresh on charging-program changes
REFRACTORY CNN
Hearth Wear Pattern Recognition

Convolutional neural network trained on hearth thermocouple time-series, identifies wall-washing patterns and tap-hole-driven wear signatures. Coupled to the inverse heat-transfer solver for hearth-protection recommendations.

Pattern signatures from 3+ years of campaign data
STOVE NN
Hot Blast Temperature & Energy

Feed-forward neural network on stove cycle data — dome temperatures, BFG calorific value, oxygen enrichment, on-gas/on-blast timing. Outputs a recommended HBT setpoint inside the envelope the stoves can sustain.

Trained on your stove-cycle history · envelope constraints applied

Operator Workflow

Approve, Defer, Reject — Every Action Logged

A recommendation is not an instruction. The operator owns the call, and the audit trail preserves the reasoning either way. The feed is designed around the workflow operators already run, not against it.

APPROVE

Operator accepts. Setpoint change is sent to the relevant DCS / HMI on a write-confirm pattern (no autopilot). Outcome captured automatically over the next 1–24 hours and stored against the recommendation.

DEFER

Operator wants more data, or the timing is wrong. Recommendation parks in the feed with a "deferred until" timestamp and re-surfaces. The model can re-rank the recommendation if conditions change.

REJECT

Operator disagrees, with a reason. The reason is high-value training data — the next monthly retraining cycle uses it to refine when this kind of recommendation should and should not be raised.

The audit trail. Every recommendation, every action, every override, every outcome is logged with timestamp, operator ID, model version, and the inputs the model saw. Exportable for ISO 9001 / IATF 16949 reviews and internal post-mortems.

What This Is — And Isn't

Decision Support, Not Autopilot

WHAT IT IS
  • A ranked, time-stamped, model-badged feed of operational levers
  • Built on your historian, your envelope, your operating data
  • Honest about confidence — including when confidence is low
  • An aid to shift handover, not a replacement for the handover meeting
  • Audit-logged, versioned, exportable
WHAT IT ISN'T
  • An autopilot that moves setpoints without operator approval
  • A claim that every recommendation is right — some will be wrong
  • A replacement for metallurgist judgement on edge-case decisions
  • A static dashboard — recommendations re-rank as conditions change
  • A black box — every model has a badge and an explanation path
FAQ

What Operators & Plant Heads Ask First

How many recommendations does a shift typically see?

Three to seven active items at any moment, roughly. The feed is tuned to surface what matters now — not to maximise the number of suggestions. If the feed shows fifteen items, something is wrong with the tuning, not the furnace.

What if two recommendations conflict?

The feed flags it explicitly. For example, a HIGH hearth-protection recommendation that asks for tap-hole rotation may conflict with a MEDIUM coke-saving recommendation that assumed steady tap rotation. The conflict is shown on both cards and the higher-severity item takes precedence in ranking.

Can the operator override a HIGH severity recommendation?

Yes — with a logged reason. The system does not block operator authority. What it does is preserve the trail: the recommendation was raised at this time, with this confidence, the operator overrode for this reason, and the outcome was X. Useful for post-mortems and for refining future recommendations.

How quickly does a wrong recommendation get caught?

Honestly: it depends. A recommendation with a fast, observable outcome (PCI rate change, hot blast step) is validated within hours. A slow-effect recommendation (pellet ratio, burden distribution) takes shifts to validate. Wrong recommendations that don't get caught surface in the monthly retraining review against actual outcomes.

Does this connect to our DCS / HMI?

Yes, with deliberate friction. We integrate with major DCS systems (Siemens, ABB, Rockwell, Honeywell) on a write-confirm pattern — the recommendation can populate a setpoint candidate, but the operator's confirmation is what actually moves it. Talk to a deployment engineer for the integration scope on your stack.

What happens if the feed disagrees with our metallurgist?

The metallurgist wins. The feed is decision support, not authority. When that happens, the disagreement gets logged, the metallurgist's reasoning is captured, and the model retrains on it. Most of our highest-value model improvements over the first six months come from exactly these disagreements.
