In steel mills, iron slabs after manufactured are transported by magnetic cranes (lifting magnet). If the temperature of the iron slab is too high, the magnetic force of the crane gets weakened, so the temperature of the iron slab must be reduced to an appropriate temperature.
Therefore, it is necessary to go near to the crane to measure the surface temperature of the iron slab before transportation, but this is a time consuming and labor intensive process.
Example of Installation
The thermometer for magnetic cranes is a system consisting of (1) a thermometer IT 480F, ( 2 ) a measuring unit, and ( 3 ) a display unit.
When the temperature of the final product coil is high, the stopper rubber melts and adheres to the coil.
To prevent this from happening, the surface temperature of the coil must be measured.
HORIBA offers the IT-480 series for automatic measurement and the IT-545 series for manual measurement.
