Smart steelmaking dispatch toward semi-autonomous operation
01
Overview
Ladle ID and smart dispatch for 47 ladles, fully online since June 2022: 99.5% recognition accuracy, 95%+ model adoption, and 3 crane misloading events intercepted.
02
Challenges
Heavy crane traffic and complex ladle flows make dispatch dependent on manual commands. A wrong ladle at the converter can trigger violent reactions; semi-autonomous operation demands fully automatic data capture.
- Complex flows make manual dispatch error-prone and untraceable
- Wrong ladles risk splashing and violent reactions
- Semi-autonomous operation requires automatic logistics capture end to end
03
Solution
A three-layer system — identity, smart dispatch and safety interlock: accurate data, system-directed cranes, and a hard safety floor.
- Identity layer47 maintenance-free HT tags, one code per ladle
- Reader networkFull coverage of charging, converter, refining and LF positions with live ladle locations
- Smart dispatchCrane and matching commands generated from live positions and heat state; 95%+ adoption
- Safety interlockAutomatic checks between ladle grade and target position; 3 misloads locked out and alarmed
