Calibration device and calibration method for radiation pyrometers in a passage - heat treatment device for metal strip

摘要

A calibration device for radiation pyrometers for process control of a passage - heat treatment device for metal strip uses a band sample to be treated of the band collar. The band section, with a high current source to a nominal value is regulated or vulcanizing a plurality of staggered value heated to temperatures in such as the production line in the heat treatment station. The temperature of the band sample is on one side with a to the piece of ribbon pressed-on temperature probe and on the other side with a radiation pyrometer measured. A rule - and control unit determines, from the measured values of the setpoint temperature values for radiation pyrometers and transmits this to the process control system of the passage - heat treatment device further the calibrating device can be obtained under the same protective gas, which is also low flammability may be, as can be operated in the production plant.
