Abstract

A method to control exhaust fumes aspiration during a steelmaking process in a steelmaking ladle, the method comprising the following steps: - Capturing at least one image of flames escaping from the top of the steelmaking ladle, - Calculating at least one value representative of the size and/or the intensity of the flame based on the at least one captured flame image, - Measuring a pressure representative of the pressure of the aspired fumes, - Controlling the aspiration of fumes based on said value representative of the flame and on the measured pressure.
