Automatic Ladle Gas Coupling System
The Automatic Ladle Gas Coupling
System is used in the following areas
of the steel mills:
• Ladle treatment and deslaging
station
• Ladle transfer car
• Ladle turret
• Vacuum tank
• etc.

Automatic Ladle Gas Coupling System
What are the most important aspects?
• “Mill-worthy” - eliminates operator fatigue, enhancing consistency and repeatability • - reliable in harmful environment, efficient gas use
• Safety – provides safety for operators, he is not staying anymore in harmful area
• Performance – improved performance for steelmaking costumers
• Time – provides rapid connection to minimize the gas purging interruption and enables operators to perform other duties
• Self protection – predetermined breaking point protects the machinery. Quick exchange of the “break- away” part
• Self positioning – large coupling tolerance
• Protected position – system is protected from harmful environment
• Repetition – repeatable process

Automatic Ladle Gas Coupling System
Typical Arrangement
• ALGCS-unit mounted on the ladle car
• One (1) funnel at each ladle
• Media control panel (MCP) can be
installed flexibly, either direct at the
ALGCS or several meters far away
from the ALGCS (where possible)
