The work presented here has been effectuated during an internship at Saint-Gobain Isover, which is a company that manufactures glass wool, used for the insulation, in particular of the buildings. The glass wool is made thanks to furnaces (electrical or flame) to melt the glass. These furnaces are worn by the glass corrosion and that can induce issues and a limited lifetime of the furnace, so this wear has to be controlled. The aim of this work is to create new tools, especially as curves, to study and control this wear. These new tools must be simple to use and the most automatic possible to save time.
