Abstract

A device for determining the topography of the burden surface in a shaft furnace ( 10 ), the device comprising a radar device ( 20 ) that scans the burden surface ( 18 ) and has an antenna device ( 22 ) arranged in the area of a furnace cover ( 13 ), the antenna device being arranged on an axis of rotation ( 24 ) that is inclined in relation to a vertical axis ( 15 ) of the shaft furnace at an angle of inclination α and being rotatable about the axis of rotation by means of a drive device in such a manner that a radar fan beam ( 28 ) formed by the emitted radar radiation of the antenna device is incident upon the burden surface along a profile line p and sweeps across the burden surface as the antenna device rotates.

Claims (7)

1. A device for determining a topography of a burden surface in a shaft furnace, the device comprising: a radar device scanning a burden surface of a shaft furnace; an antenna forming part of the radar device and emitting radar radiation, the antenna being arranged proximal a furnace cover and on an axis of rotation inclined in relation to a vertical axis of the shaft furnace at an angle of inclination between 20° and 60° in relation to the vertical axis; and a drive rotatably driving the antenna 360° about the axis of rotation in such a manner that a radar fan beam formed by the emitted radar radiation of the antenna is incident upon the burden surface along a profile line p and sweeps across the entire burden surface as the antenna rotates.

2. The device according to claim 1 , in which the antenna device is arranged in an antenna plane oriented vertically to the axis of rotation.

3. The device according to claim 1 , in which the antenna has at least two antenna modules.

4. The device according to claim 3 , in which the antenna modules are arranged in a shared antenna plane.

5. The device according to claim 3 , in which the antenna modules are arranged in different antenna planes inclined at an angle γ to the axis of rotation.

6. The device according to claim 5 , in which the antenna planes are arranged at different angles to the axis of rotation.

7. The device according to claim 1 , in which the radar device is a single radar device.
