Synchronizing Steel: AI-Driven Scheduling for Next-Gen Meltshops
Transforming complex EAF-CCM interactions into seamless, automated production flows with real-time digital twin simulation and predictive analytics.
Eliminating Bottlenecks through Intelligent Thermal & Material Synchronization
In high-heat metallurgy, even a five-minute delay in a ladle furnace can cascade into massive energy losses and stalled casting sequences. This project implemented EBI SIM, a core pillar of the EBI Platform, to bridge the gap between manual planning and the volatile realities of the shop floor. By creating a high-fidelity digital twin of the meltshop—including two Electric Arc Furnaces (EAF) and three Continuous Casting Machines (CCM)—we provided engineers with a “crystal ball” to test schedules against real-time constraints before execution.
The solution doesn’t just manage machines; it empowers operators. By integrating live data from the plant floor into an AI-driven scheduling engine, we replaced “best-guess” manual planning with optimized, constraint-aware logic that accounts for scrap composition, bridge speeds, and metallurgical rules.

Background & Goals
The primary objective was to modernize a legacy meltshop environment where production planning was siloed and reactive. The client faced a “Talent Gap” where veteran knowledge was retiring, leaving a void in complex operational decision-making. Our goal was to codify this expertise into the EBI SIM platform, ensuring that even junior “Apprentice” level planners could manage complex steel grades and sequences with the support of AI, effectively “Bringing Talents Back to Industry.”
Implementation & Methodology
Following our Agile Implementation strategy, the project began with a data-mapping phase to connect OT (Operational Technology) sensors to the EBI Platform. We modeled the physical constraints of the facility—including crane trolley speeds and preheating durations—into an AnyLogic-based simulation. This allowed us to run “What-If” scenarios, comparing multiple production schedules (e.g., Scenario 1 vs. Scenario 2) to select the path with the lowest energy footprint and highest throughput before the first heat ever began.
