Ladle treatment with stirring gas by purging plugs is an essential issue within secondary metallurgy. Reliable performance of the stirring plugs in steelmaking ladles is a key factor for accurate steel production.
Disturbances due to loss of stirring efficiency and non-stirring events have impact on treatment times and achievement of steel quality requirements.
Check Valve LCV34
To prevent infiltration at the ladle purging plug a check valve could be installed in the supply piping. The check valve maintains the immediate pressure at the plug in case the supply line discharges.
The check valve type LCV34 is in a stainless steel housing with a spring suitable for higher temperatures. Due to the spring forced closing of the valve it functions in any mounting orientation
