- 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.
