Movement and position of temperature and sample lances

Lance manipulators rotate in total, can move up and down and actuate the lances and sample taking arms. Knowing the lances’ actual depth penetration in the steel bath, as well as the maximum insertion and retraction positions, is essential information in order to ensure optimal operation. The manipulators and the lances’ actual positions in the furnace are identified and measured via a combination of absolute encoders and inductive proximity sensors. The steel plant’s harsh environment is no problem for these robust and resilient sensors.
