Installation notes
- 1Always pre-heat shroud to 800–1000°C using lance pre-heater before first use
- 2Apply anti-oxidation paste to upper flange seating area
- 3Argon purging: connect purge line before opening ladle, purge at 10–15 Nl/min
- 4Check bayonet lock engagement before casting, loose connection causes steel splash
