DEVICE FOR DETERMINING THE TOPOGRAPHY OF THE CHARGE SURFACE IN A SHAFT FURNACE

摘要

The invention relates to a device for determining the topography of the charge surface in a shaft furnace (10), comprising a radar device (20) which scans said charge surface (18) and has an antenna device (22) arranged in the region of a furnace cover (13), said antenna device being arranged on a rotational axis (24) which is at an incline, at an angle of inclination α, relative to a vertical axis (15) of said shaft furnace, and being rotatable about said rotational axis by means of a drive device such that a radar fan (28) formed from the emitted radar radiation of the antenna device is incident upon the charge surface along a profile line p, and sweeps across said charge surface as the antenna device rotates.
