Abstract

PURPOSE: To enhance the accuracy in measuring the profile of the heap of charge in a blast furnace by a method wherein a laser beam of a short pulse length is used for scanning the top surface of the heap of charge, and the results of plural runs of laser spot position measurement are arithmetically processed.
CONSTITUTION: The laser beam oscillated by a laser oscillator 4 is projected into the interior of the blast furnace 1 through a tranparent window 6 provided at a partition wall 2 and is scanned across the top surface 7 of the heap of charge 3. In this case, a short-pulse laser beam such as that of a giant pulse laser is used for the scanning, and the beam is projected for a plurality of times onto the top surface 7 of the heap 3. Each spot position is measured from the spot 8 formed by each of the pulse laser beams, the position measurement being repeated plural times. The average of measured values is obtained, for example, by taking an arithmetic average of the measured values. By this method, the influence of dicing upon the measuring accuracy can be minimized and the heap condition in the blast furnace 1 can be measured accurately.
