Title:
レベル計測装置
Document Type and Number:
Japanese Patent JP6822388
Kind Code:
B2
Abstract:
Provided is a level measurement apparatus which uses microwaves and can measure the surface of slag during blowing more accurately than the prior art. In a level measurement apparatus 10, a transmission antenna 11 and a reception antenna 12 are disposed above a hood opening section 6 and thus far away from a slag surface 3, and attachment of a base metal and slag to the transmission antenna 11 and the reception antenna 12 can be suppressed. Thus the slag surface 3 during blowing can be measured more accurately than in the prior art. Also, in the level measurement apparatus 10, the diameter φ1 of the transmission antenna 11 is formed larger than the diameter φ2 of the reception antenna 12, and unnecessary reflection during level measurement of the slag surface 3 can be prevented by disposing the transmission antenna 11 and the reception antenna 12 above the hood opening section 6, and the slag surface 3 during blowing can be measured more accurately than in the prior art.
