Abstract

Proactive maintenance methods and their effects on operational availability are studied in a critical hydraulic system of the Rautaruukki Raahe steel plant in Finland. Systematic analysis approach and novel research results are presented. The case study concentrates on proactive maintenance tools and especially on the effects of the considerable improvements in oil cleanliness, performed within the few recent years. The particle populations, ISO cleanliness levels and fault history are studied in a four year time period. Further the condition monitoring program and predictive maintenance methods in addition to conventional preventive and corrective maintenance are covered in the cost analysis. The results show that the equipment and operations for effective removal of oil contaminants may have extremely short pay-back times by preventing failures and reducing production downtime. The costs of predictive maintenance were low compared to potential savings. Beside the savings due to reduced downtime and repair costs the cost savings are through the extension of equipment life and lengthening service intervals, remarkable.
