DISPOSITIF ET PROCÉDÉ DE DÉTECTION DE SURFACE DE MATÉRIAU DE CHARGE DE HAUT FOURNEAU

摘要

The present invention is formed by having an angle variable reflection plate installed at an opening section at one end thereof and an antenna installed at the other end thereof, and is provided with: a guide part inserted into a furnace through an opening of a side wall of a blast furnace; a guide part moving means for moving the guide part inside and outside the furnace; a guide part pivoting means for pivoting the guide part at a prescribed angle around the axis thereof; a detection wave transmitting and receiving means connected to the antenna; and a reflection plate tilting means for changing the tilt angle of the reflection plate to the antenna side. At the time of measurement, the opening section of the guide part is projected into the furnace, the guide part pivoting means and the reflection plate tilting means are driven to scan the surface of the charge in the furnace in a planar or linear manner, and at the time of non-measurement, the opening section is retracted to the outside of the furnace.
