Nucor Steel Gallatin purchases new valve train for EAF chemical energy system from INTECO PTI

Nucor Steel Gallatin has recently purchased equipment for the complete replacement of their existing EAF oxygen injection and burner control trains on their twin shell Electric Arc Furnace.  The system includes the equipment and programming for an air/nitrogen purge through both the oxygen and gas lines. The system also includes remote I/O control along with modifications to the existing HMI screens and required programming. This new control train will provide the following benefits:

• Reliable Control
• Multiple Burner Programs
• Less Maintenance
• Most recent safety improvements in programming
• Pressure sensing on individual gas and oxygen lines, which can be used to detect the degree of burner blocking and purge during furnace turn around and downtime.

The gas and oxygen capabilities of this train are designed to allow the supply of chemical energy of supersonic oxygen injection to all 6 burner positions on the EAF.
