EAF Simulator: an EAF process digital twin for training steelmakers on rigorous thermodynamic equilibrium

Business Impact

Practice off-grade heats, overruns and emergencies in the twin: a mentor cannot stage them on a running furnace

Go live on your furnace in weeks, adapting the model on a handful of heats instead of hundreds

Compare regimes and charge mixes on cost in the shop's own kWh/t, Nm³/t and kg/t before anything changes at the furnace

Grade every heat 0-100 on its metallurgical result, tracked per group and per trainee in the LMS

Reuse one calculation core across BOF, ladle furnace, vacuum degassers, AOD and casting

Close mass balance to the kilogram and energy balance to 0.025% of heat input

How It Works

01

Full Equilibrium Core

Metal-slag-gas equilibrium with no element recovery coefficients: oxygen split, slag oxidation, nitrogen and phosphorus all fall out of a single calculation

02

Reaction-Zone Kinetics

Each step draws metal and slag into the zone in proportion to stirring intensity, leaving one unit-specific parameter and letting an hour-long heat compute in seconds

03

Configurable Device Model

Transformer, burners, buckets, tapping and invisible losses hand standard mass and energy values to one core, and the same configuration drives the 3D scene and control panel

04

Shop-Grade Energy Balance

Itemized the way production accounts for it, with scrap tracked as batches that melt faster under stirring and freeze a shell below the liquidus

05

Built-In Training Loop

Assignments are generated from a steel grade, with goals, ranges and weights in an editable config, and the finished heat is graded automatically
