Overview
Smart ladle management online May 2023, with short-pulse radar crane positioning: 3 cranes, 7 radar hosts, 8cm accuracy and 100% ladle ID accuracy.
02
Challenges
Crane operators work blind from height, so positioning error hurts safety and efficiency; ladle records travel by word of mouth; ordinary positioning drifts badly in hot, dusty shops.
01Blind lifting causes large positioning errors at the converter
02Manual ladle records diverge from reality
03Ordinary ranging drifts and needs heavy maintenance in heat and dust
03
Solution
One integrated system: EMMA ID for ladle identity, short-pulse radar for position, and a management platform for records and decisions — cross-validated data.
Ladle ID
EMMA stations auto-identify ladles end to end with zero manual entry
Crane positioning
Short-pulse radar ranging guides ladles into place at 8cm accuracy in real time
Smart management
Lifecycle records, heat-state tracking and maintenance alerts in one platform
Data loop
ID and positioning data converge on a central screen for at-a-glance dispatch

Results
ID accuracy holds at 100%, crane placement at 8cm; first-try ladle positioning improved markedly, and records now always match reality — daily reviews run off one screen.
