Claim 1:
2. The method as in claim 1, further comprising:
calculating an area of a section of the tunnel defined by said at least one conveyor channel and by said at least one hood disposed above, based on knowledge of the current hood height,
calculating an area of the metal charge corresponding to the area of the section occupied by the metal charge in transit on the basis of the profile detected,
calculating a fumes passage area as the difference between said area of the section of the tunnel and said area of the metal charge,
calculating an average passage speed of the fumes as a ratio between a current flow rate of fumes movement means and said difference between said area of the section of the tunnel and said area of the metal charge,
comparing the average fumes passage speed with a desired fumes passage speed value, and
dynamically modifying said height of said at least one hood in order to obtain said desired fumes passage speed value.
