Abstract
A process to continuously determine by an optical arrangement the profile of a charge fed into a blast furnace in which the surface of the charge is swept by a beam of light moving in a plane intersecting the surface so as to produce at the intersection of the plane with the surface a luminous trace, observing the luminous trace from a point outside the sweeping plane, and determining on the basis of the data defining the sweeping plane, the observation point and the direction of observation with respect to the plane the true position of the points constituting the luminous trace; and an apparatus for carrying out the process and including an illuminating system for illuminating the surface of the charge with a beam of light sweeping in a plane intersecting the surface to produce on the surface a luminous trace and a reception system cooperating with the illumination system for producing a picture of the actual profile of the luminous trace.
