Title:
POWDER RATIO MEASUREMENT DEVICE, POWDER RATIO MEASUREMENT SYSTEM, AND BLAST FURNACE OPERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/189262
Kind Code:
A1
Abstract:
This powder ratio measurement device is capable of highly accurate real-time measurement of the powder ratio of powder adhered to the surface of a lump of a substance. This device is for measuring the powder ratio of powder adhered to the surface of a lump of a substance, and comprises an illumination device for illuminating the lump of the substance, a spectroscopy device for separating the light reflected by the lump of the substance and measuring a reflectance spectrum, and a calculation device for extracting a feature value from the reflectance spectrum measured by the spectroscopy device and calculating the powder ratio from the extracted feature value.
