“…5 and 6). Although atmospheric infrared radiation can be neglected at short distances from the target surface, infrared temperature measurements are perturbed by the surrounding radiation [23,24]. The heating efficiency of the induction plate depends on the geometry of the inductor and the position of the magnetic field relative to the workpiece.…”

The purpose of warm forming is to reduce the deformation resistance, and therefore the formation of products at reduced pressures. A key problem associated with warm sheet metal forming is uniform heating of the material to a required temperature. This task is carried out mostly by using resistance heating plates. The article presents the results of the analysis of the thermal state of a heating plate for induction heating of an AMS 5604 stainless steel sheet. To determine the temperature distribution on the sheet surface an FLIR P 640 thermal imaging camera was used. It was found that the temperature difference on the outer surface of sheets preheated to the temperature of 900°C was about 300°C. A large difference in the temperature on the outer surface of the sheet means that the analysed device cannot be successfully used in the heating process of stainless steel sheets. After the application of a layer of graphite on the sheet surface to increase the emissivity, areas of low emissivity as a result of graphite detachment from the sheet surface were observed.

Thermal mapping has been implemented since the late eighties to establish the susceptibility of road networks to ice occurrence with measurements from a radiometer and some atmospheric parameters. They are usually done before dawn during wintertime when the road energy is dissipated. The objective of this study was to establish if an infrared camera could improve the determination of ice road susceptibility, to build a new winter risk index, to improve the measurements rate, and to analyze its consistency with seasons and infrastructures environment. Data analysis obtained from the conventional approved radiometer sensing technique and the infrared camera has shown great similarities. A comparison was made with promising perspectives. The measurement rate to analyse a given road network could be increased by a factor two.

“…A mirror was installed in the FOV of the camera, along with a surface painted with Nextel 811-21, which emissivity is considered as stable and equal to 0.97 [11]. The one of the mirror has been determined to 0.063 [12].…”
