International Aluminium Journal - Practical Infrared Thermometry for Aluminium Hot Rolling Mills

Monday, February 25, 2019

Fiona Turner, Physics Section Manager at AMETEK Land, looks at how aluminium presents significant challenges for accurate infrared temperature measurement and how those challenges can be overcome with modern infrared technology.

International Aluminium Journal Feb 2019Aluminium presents significant challenges for those who need to measure its temperature by non-contact thermometry. The material has low emissivity which varies with wavelength and surface condition, and aluminium is processed at lower temperatures than most metals so there is fundamentally less emitted energy.

For infrared temperature measurements of rolled or extruded aluminium surfaces to be taken successfully, sensitive multi-wavelength pyrometers or infrared thermometers are required, which can interpret the complex emissivity behaviour in real time.
