Title:
LEVEL MEASUREMENT METHOD AND LEVEL MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/124377
Kind Code:
A1
Abstract:
Provided are a level measurement method and a level measurement device which are capable of measuring, by using microwaves, a slag surface during blowing more accurately than before. The level measurement device 10 removes a level measurement value determined as a noise (SP9), and specifies the level of a slag surface 3 in a furnace on the basis of only a level measurement value remaining without being removed (SP8). Accordingly, in the level measurement device 10, the specifying of a level of the slag surface 3 in the furnace on the basis of an erroneous level measurement value generated by bare metal can be suppressed. Thus, the slag surface 3 during blowing can be measured more accurately than before.
