Title:
LEVEL MEASURING DEVICE
Document Type and Number:
Japanese Patent JP2019105526
Kind Code:
A
Abstract:
To provide a level measuring device capable of performing measurement of slag surface during blowing more accurately than before using a microwave.SOLUTION: In a level measuring device 10, a transmitting antenna 11 and a receiving antenna 12 are disposed above a hood opening 6 and are separated away from a slag surface 3 in a furnace, so that the adhesion of slag or ground metal to the transmitting antenna 11 and the receiving antenna 12 can be suppressed accordingly and the measurement of the slag surface 3 during blowing can be performed more accurately than before. Further, in the level measurement apparatus 10, a diameter φof the transmitting antenna 11 is larger than a diameter φof the receiving antenna 12, and the transmitting antenna 11 and the receiving antenna 12 are disposed above a hood opening 6, so that unnecessary reflection at a level measurement time of the slag surface 3 can be suppressed and measurement of the slag surface 3 during blowing can be performed more accurately than before.SELECTED DRAWING: Figure 1
