Next Generation of Thermal Imaging Technology Solves Aluminium Temperature Control Challenges for Operators
LAND® highlights the increasing numbers of furnace operators who are achieving a competitive advantage by switching to the latest thermal imaging systems to overcome the difficulties of remote measurement of liquid aluminium.
Representing an advance from traditional single-spot temperature measurement methods used for many years, the new generation of borescope furnace technology enables an unparalleled view inside melt furnaces to accurately and continuously profile the temperatures within the furnace without disturbing the process.
Operators in the aluminium sector can benefit from optimised processes, enhanced efficiency and quality, and improved safety after implementing thermal imagers into automated process control systems. This generates extensive amounts of crucial thermal behavioural data that was not previously available to them.
Aluminium is a challenging material for measurement instruments to achieve accurate readings due to several characteristics, including a low emissivity which varies in value depending on oxide layers and type of alloy, preventing direct correlation of the Infrared radiation intensity emitted by the metal with its temperature.
LAND’s advanced radiometric infrared borescope MWIR-b-640 thermal imager with spectral filtering uses a mid-range wavelength of 3.9 μm to achieve a clear, continuous view through heavy smoke and hot furnace atmospheres, overcoming the difficulties caused by reflections from the hotter walls, fumes and particulates, dross build-up and surface materials which impact the measured signal.
With a wide-angle field of view, the LAND camera allows multiple areas to be imaged and measured simultaneously, enabling high-resolution furnace measurement image data to be taken, stored and trended over the lifetime of the furnace to facilitate the early detection of leaks and temperature variations helping to optimise processes.
Additionally, accurate temperature measurement of liquid aluminium is essential for process efficiency to ensure the integrity of the finished product. If the temperature is too hot, this will alter the chemical and physical properties and the casting will not meet the required specifications. If the temperature is too low, the molten metal will not flow into all the cavities and apertures of the casting due to solidification.
Continuous temperature allows aluminium operators 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. Changes over the melt objects can be analysed to predict melt rates and process transitions, while dross formation can also be monitored.
