Document Type and Number:
Japanese Patent JP2019112675
Kind Code:
A
Abstract:
To provide a level measurement method and a level measurement apparatus capable of measuring by using microwaves a slag surface during blowing more accurately than before.SOLUTION: According to a level measurement apparatus 10, a level of a slag surface 3 in a furnace is determined based only on a level measurement value left without being excluded after excluding the level measurement value identified as a noise. The slag surface 3 during the blowing can be measured by using the level measurement apparatus 10 more accurately than before because the level of the slag surface 3 in the furnace can be suppressed from being determined on the basis of a wrong level measurement value generated by an in-furnace skull.SELECTED DRAWING: Figure 8
