The Torpedo Car Monitoring System of Automation Technology is a turn-key solution for automatic Breakout-Early-Warning to guarantee plant safety. Trough the use of infrared cameras, our monitoring system allows a reliable assessment of the remaining lifetime of the refractory lining by monitoring the torpedo cars during operation.

System Tasks

Generally, the maintenance intervals for refractory material are determined based on experience. For safety reasons, these time intervals are commonly quite conservative. However, infrared cameras mean a alternative solution for determining the torpedo car condition because the external surface temperature is a reliable indicator of the condition of its refractory lining. The number of heats can thus be maximized without any safety issues and the re-lining can be scheduled more precisely. Considering the high costs for the refractory maintenance, the system can significantly contribute to a reduction of the production costs of steel.

Key Features
  • Fully automated measurement sequence; no
    operator interaction required
  • Shape recognition function for monitoring the
    complete surface on topedo cars in motion with
    very high measurement accuracy
  • 100% Traceability: Automatic storage of images,
    measured temperatures and process related data
  • Advanced data management and analysis with
    database and web server
  • Various interfaces for connecting to your process
    control, data management and visualization

Key Advantages
  • Increased transportation safety
  • Prevention of liquid metal breakouts
  • Early identification of areas with increased wear
  • Cost savings: maximization of refractory lining service life
    without safety risks
  • Optimized refractory maintenance planning
  • Efficiency comparison of refractory linings

The external surface temperature of a torpedo car is a reliable
indicator of the condition of its refractory lining. Therefore,
infrared cameras are the perfect solution for a contact-free
monitoring of the refractory material during operation.
Once a temperature measurement is performed, the thermal data
is analyzed and the status of the torpedo is displayed through the
web interface of the system. All thermal images, the temperature
information and other process related data is stored in the
systems database, enabling dedicated analyses of the refractory
lining status.
