Resumo
Within the rolling equipment of hot strip rolling mills the condition of the mill stands is of major importance. Bad mechanical conditions can lead to rolling problems e.g. roll positioning issues, thickness errors, cambered strips, tail end cobbles, strip surface defects or unplanned roll changes. SMS groups Genius CM® program package for monitoring of machine components was enriched by new functions that have been developed and applied focusing on the integrity of the mill stand equipment. These are analyzing: • the parallelism of the rolls indicating unacceptable wear conditions in the stands • the hysteresis of the roll positioning equipment • and the roll force measurement equipment. Model based calculations and helping functions are targeting at optimal user support to determine the most critical equipment conditions and focus on the relevant steps for maintenance and required service actions. The paper provides detailed information regarding the new functions and the implementation at SSAB as well as examples of possible use cases
