Productivity Increase at ArcelorMittal Tubarao Hot Strip Mill (Room 306)

ArcelorMittal Tubarão HSM productivity has increased gradually and consistently over the last four years, based on increasing charging temperature, furnace efficiency, decreasing roughing mill and finishing Mill cycle times, and tuning models for mill pacing control and slab design. This paper will show the path that was followed by the Tubarão HSM team to achieve more than a 20% productivity increase, resulting in a production increase of more than 700 million tons of hot coils per year.
