Predictive maintenance technologies and their effect on unscheduled maintenance downtime
- LTV Steel Co., Cleveland, OH (United States)
In the past, the Cleveland Works Iron Producing Department recognized the need for increased uptime. This recognized need brought about a focus on time based preventive maintenance techniques such as, cable replacements, mud gun replacements, and a reline philosophy where large pieces of equipment were replaced every five years whether they needed it or not. This philosophy increased the use of time based scheduling with a focus on scheduled downtime to do wholesale change outs of pieces of equipment and components. The company recognized the need for a change to increased asset utilization. The company only wants to repair or replace equipment based upon its condition, not time. In order to do this one has to focus on better equipment histories and embrace predictive maintenance technologies. Better recordkeeping systems are required in order to track equipment histories such as a CMMS (Computerized Maintenance Management System). The company set up a program through the Maintenance Services and Strategies Department to use vibration analysis to baseline rotating machinery and then report on a monthly basis any needed corrective actions. The performance of vibration analysis program, as well as an oil analysis program, ultrasonic testing, and infrared camera analysis is described.
