Abstract

ACCURATE MODELING IN A HOT STRIP MILL IS CRITICAL NOT ONLY FOR QUALITY CONTROL BUT ALSO FOR ENHANCING PROCESS STABILITY, AND PRODUCTIVITY, MINIMIZING UNPLANNED STOPPAGES, REDUCING GREENHOUSE EMISSIONS, AND IMPROVING OVERALL COMPANY COMPETITIVENESS. THIS PAPER EXAMINES RECENT ADVANCEMENTS IN THE ONLINE SET-UP MODEL AT USIMINAS' HOT STRIP MILL, FOCUSING ON SUBSTANTIAL SYSTEM UPGRADES AND THE DEVELOPMENT AND REFINEMENT OF MATHEMATICAL MODELS CRUCIAL FOR BOTH OFFLINE AND ONLINE OPERATIONS. BY ADDRESSING THE COMPLEXITIES OF THREADING IN THE FINISHING MILL, THE STUDY PROVIDES VALUABLE STRATEGIES ON IMPROVING PROCESS STABILITY. THE EVOLUTION OF MODEL ACCURACY IS DEMONSTRATED THROUGH THESE ENHANCEMENTS, EMPHASIZING THE CRUCIAL ROLE OF PRECISE MODELING IN SUSTAINING COMPETITIVENESS AND MEETING RIGOROUS PRODUCT SPECIFICATIONS EFFECTIVELY.
