The Electric Arc Furnace (EAF) inspection is a common activity in steel making industry. Currently, it is done visually by the operator. This type of inspection cannot map the entire EAF surface. The operator can see only a small part of the furnace through an opening used to remove the slag. Moreover, this inspection is not precise, as the operator can examine the furnace through the heat shield and only for a brief time. In addition, the visual inspection cannot find local temperature differences. Furthermore, these manual inspections are dangerous. The main goal of this project is to implement a robotic system able to make EAF safe inspections, focusing on the refractory layer and the water cooling plant.
