Abstract

With the goal to know the radial distribution of the blast flow rate in blast furnace, a work was carried out to implant a trustworthy measurement system of blast flow rate in the tuyere breast of ArcelorMittal Monlevade blast furnace A. The main methodologies of fluids flow rate had been considered, amongst which the Venturi tube, that showed to be the most viable technically. It was elaborated a mathematical study and a physical analysis for the posibility of installation of this device in a tuyere breast. The industrial test results had shown a good reliability in the developed system, with easy implementation and low cost. With this system implanted in all the 22 tuyeres of the blast furnace A, there is a expectative to be able to monitor the blast flow rate in each quadrant of blast furnace, and with this, to do correlations about wear hearth, skull formation, heat losses peaks, amongst others informations.
