The Torpedo Hot Spot Detection (THSD) system uses the latest infrared technology to monitor the temperature of the torpedo steel structure. Two infared cameras observe the torpedo cars while they are moving past the inspection site. The temperature measurements are completely automatic and require no manual interaction.
THSD automatically raises the alarm if an adjustable temperature threshold is overrun. This reliably prevents dangerous and loss-making breakouts of liquid iron. THSD automatically tracks the temperature development of all torpedos in circulation. This allows to maximize the torpedo refractory lifetime without cutback of security and helps to save remarkable costs. THSD comes with highly reliable components in a flexible structure and thus is easily adoptable to the different situations and operational modes in iron and steel plants.
