Abstract
A new induction-heated fixed-point device was developed for calibration of temperature
measurement devices typically used in laser heat treatment for the
temperature range 1000–1500 °C. To define the requirements for the calibration method, selected
measurement setups were compared as well as process data and results of
industrial processes were analyzed. Computer simulation with finite element method (FEM) and finite difference method (FDM)
was
used to optimize the system components and processing parameters of the
induction heating of fixed-point cells. The prototype of the fixed-point
device was tested successfully, and the first measuring results are presented here.
The new calibration method is expected to improve the quality and
reproducibility of industrial heat treatment processes with temperature
control.
