This paper evaluates the results of a unique ladle tracking system that is successfully installed in two melt shops in North America, and one in India. The system uses a combination of thermally and mechanically protected equipment, Radio Frequency communication devices and custom software. A ROI case for a typical plant is presented, including highlights and real world situations that were collected during continuous operations for more than two years. The system has helped to keep tracking of total steel contact in ladles, and detecting mistakes related to wrong ladle assignations and incorrect alloy additions. The PLT (Physical Ladle Tracking) has been running continuously for more than 30 months with an average RFID tag life of 8 months each, and no armors damaged or changed; with a total of more than 18,000 heats successfully tracked. The system has been proven effective and reliable in several working conditions, making the PLT a very effective way to track ladles in the steel plant.
