Ladle - SandMan
Field of use:
Ladle - SandMan
In continuation of our strategy "The future is manless", the Ladle - SandMan is
another step in this direction
It addresses two fundamental priorities on every ladle of EAF and integrated
plants:
- Precise filling of the well block with well filler sand and therefore enabling a better opening rate.
- The filling of the well block is still done manually in most plants today and tracking for a process optimization is not possible without measurements.
This unique manipulator combines both of these aspects in a robust and space
saving design.
The Ladle - SandMan pushes safety forward tremendously by removing a dangerous
everyday task and keeping operators out of harm's way.
Functions
- Automated filling process of well filler sand
- Precise dosing
- Exact placement of sand
- Temperature measurement of ladle bottom
- Visual camera inspection
- Self-standing control cabinet with data recording
Advantages
- Safe Operation from pulpit
- No manual sand dropping -> improved ergonomics
- Less sand consumption
- Improved Opening rates -> no manual lancing -> no loss of sequence -> no downgrading
- Process standardization leads to higher efficiency
- Optimized positioning & tracking
- Tracking and Analysis of potential errors
Experiences
- Installed in January 2021 at BSW
- Well received by operators
- Opening rate has increased from 93.5% to 99.5% so far
- In 24hr Operation since March 2021
- Total cycle time of 60 seconds
- Instead of 20kg, only 15 kg of well filler sand needed (107t ladle)
- Redcution by 25% well filler sand for each ladle
