Abstract

Continuous casting moulds used in automated installations casting metal melts into strands require comprehensive, reliable real-time monitoring. Currently used systems are susceptible to damage and limited to just a few sensors, as arrangements involving a higher number of sensors have proven impractical due to the substantial effort they cause when exchanging a mould. To overcome this obstacle it is suggested to use wirelessly interrogable passive surface acoustic wave (SAW) sensors for monitoring of physical parameters in continuous casting moulds, and install at least one wireless link section in the signal path between SAW sensors and their reader devices. Continuous casting moulds thus become easily exchangeable with their sensors installed, making it industrially practicable to equip continuous casting moulds with a significantly higher number of sensors than previously feasible.
