AMETEK Land’s MWIR-B-640 is able to achieve a clear, continuous view through heavy smoke and hot furnace atmospheres and provides an unparalleled view inside melt furnace.
A highly accurate radiometric infrared borescope imaging camera with spectral filtering for continuous temperature measurement and furnace profiling applications.
Accurate temperature control of liquid aluminium in pouring processes is important to ensure high-quality casting, limit emissions and reduce energy use. If continuous temperature information is available, it becomes possible to closely control the process to better plan tapping and pouring operations and to ensure the metal is heated using a minimal amount of energy.
Furnace thermal imagers provide a full image view of the melt surface without disturbing the process. The overview shows the melting process monitoring and control, optimising the process and reducing the required energy. By analysing changes over the melt objects, one can also predict melt rates and process transitions. It even becomes possible to monitor dross formation and to start quantifying when such phenomena are most prominent. Additionally, it helps support safer furnace operation, by limiting the time operators need to spend in close proximity to the furnace.
Why is it a challenge to measure aluminium?
Several of the characteristics of aluminium make it challenging for measurement instruments to achieve accurate temperature readings. For example, its emissivity is low and vastly varies with building oxide layers on the surface, and each alloy has a different value. This means it is not possible to directly correlate the intensity of IR radiation emitted by the metal with its temperature.
