Abstract
(EN)
A powder ratio measurement device is provided, which, in operation processes of a blast furnace, etc., can measure in real time with high accuracy the powder ratio of powder adhered to the surface of the material used as a raw material. This powder ratio measurement device 12, which measures the powder ratio of a powder adhered to the surface of a substance 26, is provided with a lighting device 18 which illuminates the substance 26, a spectroscopic device 16 which splits the light reflected from the substance 26 and measures the spectral reflectance thereof, and a calculation device 22 which, of the spectral reflectance at each position on the surface of the substance measured by the spectroscopic device 16, uses at least the spectral reflectance of the region where the powder is adhered, calculates a value corresponding to the surface area of the region to which the powder is adhered, and calculates the powder ratio on the basis of said calculated value.

La présente invention concerne un dispositif de mesure de rapport de poudre qui, dans des processus de fonctionnement d'un haut fourneau, etc., permet de mesurer en temps réel avec une précision élevée le rapport de poudre de la poudre adhérant à la surface du matériau utilisé comme matière première. Ce dispositif de mesure de rapport de poudre 12, qui mesure le rapport de poudre d'une poudre adhérant à la surface d'une substance 26, comprend un dispositif d'éclairage 18 qui éclaire la substance 26, un dispositif spectroscopique 16 qui divise la lumière réfléchie par la substance 26 et mesure la réflectance spectrale de celle-ci, et un dispositif de calcul 22 qui, de la réflectance spectrale à chaque position sur la surface de la substance mesurée par le dispositif spectroscopique 16, utilise au moins la réflectance spectrale de la région où la poudre adhère, calcule une valeur correspondant à la surface de la région à laquelle la poudre adhère, et calcule le rapport de poudre sur la base de ladite valeur calculée.
