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.
01Complex flows make manual dispatch error-prone and untraceable
02Wrong ladles risk splashing and violent reactions
03Semi-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 layer
47 maintenance-free HT tags, one code per ladle
Reader network
Full coverage of charging, converter, refining and LF positions with live ladle locations
Smart dispatch
Crane and matching commands generated from live positions and heat state; 95%+ adoption
Safety interlock
Automatic checks between ladle grade and target position; 3 misloads locked out and alarmed
