Title:
ROTATING CHUTE INNER SURFACE WEAR TESTING APPARATUS AND ROTATING CHUTE INNER SURFACE WEAR TESTING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/209022
Kind Code:
A1
Abstract:
This rotating chute inner surface wear testing apparatus (9) is for testing the wear of a surface of a liner (32) attached to an inner surface of a chute (21) provided in a charging device (20) of a blast furnace (10). The rotating chute inner surface wear testing apparatus (9) has: a noncontact distance measurement device (42) that is capable of being introduced into the blast furnace (10) and measuring a measured distance to the surface of the liner (32); and a wear determination unit (52) that determines the wear of the surface of the liner (32) on the basis of the measured distance measured by the distance measurement device (42). A charged material surface shape measurement device (40) that measures the three-dimensional shape of a charged material surface (24), charged in the blast furnace (10), by emitting a measuring beam of microwaves or millimeter waves thereto can serve as the distance measurement device (42).
