Title:
SURFACE PROFILE DETECTION DEVICE OF OBJECT CHARGED INTO BLAST FURNACE
Document Type and Number:
Japanese Patent JP2023042980
Kind Code:
A
Abstract:
To provide a surface profile detection device of an object charged into a blast furnace, capable of detecting the surface profile of an entire surface of a charged object, by securing a scanning region over the entire face of the charged object, irrespective of an installation state of the detection device.SOLUTION: A detection device 100 detects the surface profile of a charged object by transmitting a detection wave M toward a surface of a charged object accumulated in a furnace through an opening 2 of a blast furnace 1 provided with the charged object, and by receiving the detection wave M reflected on the surface of the charged object. The device comprises a rotary disk 120 rotating in parallel with the opening 2, an angle variable reflection plate 140 and an angle-fixed reflection plate 138 fitted to the rotation plate 120, an antenna 135 transmitting the detection wave M to the angle-fixed reflection plate 138, and a casing 170 surrounding the detection device 100. At least a part of the angle variable reflection plate 140 is installed at a position entering the opening 2 of the blast furnace 1, and a part of a bottom face side of the casing 170 is provided projecting in the blast furnace 1.SELECTED DRAWING: Figure 2
