Project Scope

Graycor Industrial Constructors performed a major upgrade and rehabilitation to ArcelorMittal’s Nos. 5 and 6 Walking Beam Furnaces at the Indiana Harbor East facility.

The major scopes of work included replacement of the following:

• All fixed and movable skids and jack posts
• All cooling water supply and interconnecting piping (the existing piping was as-built and new pipe fabricated in Graycor’s fabrication shop)
• Scale trough system
• All traveling/lift frame ramps and wheels including foundation repairs
• Furnace floor and burner refractory, plus all insulation for skids and jack posts
• Fixed floor system
• All traveling liner plates and frame centering system
• Furnace scale chutes

In addition to the above, all furnace cylinders and center links were realigned to enable better traveling frame movement.

The work was scheduled on a two-shift-per-day basis, five days per week. Work was completed in approximately 11 weeks per furnace.
