Rolling Equipment Machine Deterioration Diagnosing Device

Abstract: This degradation diagnosis device for rolling equipment includes an input/output data acquisition unit, a model identification unit, a monitoring parameter calculation unit, a monitoring parameter use determination unit, a representative value calculation unit, a representative value storage unit, and a degradation diagnosis unit. The monitoring parameter use determination unit has a category-specific monitoring parameter collection function of collecting monitoring parameters, calculated by the monitoring parameter calculation unit, for each category designated on the basis of the rolling conditions of a rolled material. The representative value calculation unit calculates a representative value for a set of monitoring parameters within a certain period for each category. The representative value storage unit accumulates, for each category, representative values in a learning period designated from the start of monitoring. The degradation diagnosis unit has a category-specific degradation determination function of determining the presence or absence of degradation for each category.
