Embodiment Construction

[0027] figure 1 Shown is a shaft furnace 10 which essentially consists of a furnace lower part 11 , a furnace upper part 12 and a furnace cover 13 , in which a charging device is integrated, which is designed here as a rotating chute 14, the charging device can be pivoted about a vertical axis 15, so that the pouring ramp 17 connected to the funnel opening 16 of the rotating chute 14 can be positioned in a defined manner, which can be positioned relative to the vertical The axis 15 is adjusted in terms of inclination.

[0028] The rotating slide 14 is used to alternately supply the shaft furnace 10 figure 1 The layers of coke and charge are explicitly not shown in detail in , where layers that are defined as precisely as possible are sought in order to achieve a reproducible blast furnace process. For this reason, it is necessary to determine the surface topography of the topmost layer as precisely as possible before applying it to subsequent layers.

Abstract

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 alpha, 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.

Description

technical field [0001] The invention relates to a device for determining the topography of a charge surface in a shaft furnace, which has a radar device which scans the charge surface and which has an antenna device arranged in the region of the furnace roof. Background technique [0002] The processes taking place in the shaft furnace are primarily determined by the layered structure of the coke and charge layers arranged in the furnace chamber. To form the layers, the furnace is charged with coke and charge through the charging opening, which is arranged in the furnace cover, and in which charging device is arranged, which can be wound around the shaft of the shaft furnace. Rotating towards the axis, the technical term for this charging device is called a swivel slide (Drehschurre), which has a tilting slope whose inclination relative to the vertical axis is adjustable. The rotating slides allow the shaft furnace to be alternately supplied with layers of coke and charges,...
