10 Adaptation of temperature level

By changing the emissivity ratio, the difference between the measured temperature

level and true temperature can be compensated�

For this purpose, a comparison measurement with an immersion lance is required�

Adjust emissivity ratio in such a way that the measured values coincide� An increase

in the emissivity ratio results in a low temperature value�

The graph shows an approximation of the influence of the emissivity ratio setting on

the change in temperature value�

1 Ratio correction
2 Temperature difference [°C]

Experience has shown that the following settings apply as a first approximation

- grey pig iron 101

- spheroidal graphite iron 104
However, these values may differ in practice� After changing the emissivity ratio,

carry out a new control measurement�

The emissivity ratio is set as follows:
