Machine-learning guidance for hot strip mill slab discharge

NLMK reported a 5% shorter slab discharge interval with machine-learning guidance

WorkingCompany's own claimOfficial ↗

Problem

Operators manually timed slab discharge from reheating furnaces, balancing collision risks against temperature requirements and mill throughput.

Approach

NLMK Lipetsk introduced a model that analyzed slab properties and mill conditions. It calculated travel time to the rolling mill and prompted the operator to release the next slab. The project began in late 2019.

Results

5%reduction in slab discharge interval reported by NLMKCompany's own claim[1]

Takeaway

The system gave operators timing prompts. The reported 5% improvement concerned discharge intervals, without a quantified percentage increase in mill output.
