AOD Vessel Repair

A northeastern Pennsylvania specialty steel mill contacted The Rose Corporation about repairing one of their AOD Vessels.

Argon Oxygen Decarburization (AOD) is an advanced technology for the refinement of iron, nickel, and cobalt-based alloys. An AOD vessel allows for the introduction of oxygen and inert gas (argon or nitrogen) below the surface of molten metal.

After years of using their AOD Vessel under extreme heat conditions, the center main body bulged out of round by as much as 3”. This bulge made it impossible to fit into the trunnion ring that supports it.

We were contracted to replace the center section (1-1/2” thick steel cylinder). Time was of the essence – this AOD Vessel had to be repaired, stress relieved, tested, and returned in less than 5 weeks.

We have also been contracted to build a new duplicate AOD Vessel by the same specialty steel mill.
