Title:
IN-FURNACE MONITORING DEVICE AND IN-FURNACE MONITORING METHOD FOR BLAST FURNACE TOP
Document Type and Number:
Japanese Patent JP2022115232
Kind Code:
A
Abstract:
To visualize a low-brightness region in a furnace when monitoring the inside of the furnace using an imaging device.SOLUTION: An in-furnace monitoring device is equipped with an imaging device for capturing a deposition surface 13 of raw materials to be charged into a furnace top and an inner furnace wall 15, and a control unit for processing an image captured by the imaging device. The control unit divides the captured image into a central region A including a central flow 14 formed at the center of the deposition surface 13 and the other region B excluding the central region A. The control unit performs image processing to cause the brightness of the image in the other region B to be higher than the brightness of the image in the other region B at the beginning.SELECTED DRAWING: Figure 2
