A device for determining the topography of the burden surface in a shaft furnace (), the device comprising a radar device () that scans the burden surface () and has an antenna device () arranged in the area of a furnace cover (), the antenna device being arranged on an axis of rotation () that is inclined in relation to a vertical axis () of the shaft furnace at an angle of inclination &#x3b1; and being rotatable about the axis of rotation by means of a drive device in such a manner that a radar fan beam () 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.

Device for determining the topography of the burden surface in a shaft furnace

The invention relates to a method for regulating the flow rate and for slowing down non-ferromagnetic, electrically conducting liquids and melt streams through magnetic fields, in particular in the tapping of metallurgical containers such as blast furnaces and melt furnaces. The method is characterized in that the melt stream is routed in a closed routing element using at least one stationary magnetic field with a constant polarity, at least one stationary magnetic alternating field or using a multi-poled magnetic travelling field, in such a way that the magnetic field lines transversally penetrate the melt flow across the entire cross section thereof and such that a voltage is induced in the melt stream by the magnetic fields, there being eddy currents induced thereby in the melt stream that are disposed radially and axially when a stationary magnetic field of constant polarity is used and that are disposed axially when a stationary alternating magnetic field or electromagnetic travelling field is used, and that due to the interactions between the magnetic fields and the eddy currents forces are generated that can affect the flow rate of the melt stream.

The invention relates to a method for regulating the flow rate and for slowing down melt streams through magnetic fields in the tapping of metallurgical containers such as blast furnaces and melt furnaces. The method is characterized in that the melt stream is routed in a closed routing element using at least two magnetic fields disposed in series one after the other in the flow direction of the melt, said magnetic fields having a constant polarity opposite to one another, in such a way that the magnetic field lines transversally penetrate the melt flow across the entire cross section thereof and such that opposite voltages are induced in the melt stream by the magnetic fields, there being at least three eddy current fields produced thereby in the melt stream that are disposed axially one after the other, and that due to the interactions between the magnetic fields and the eddy currents forces are generated that can be used to reduce the flow rate of the melt stream.

A regulating device regulates the flow rate of non-ferromagnetic, electrically conducting liquids and melt streams through magnetic fields inducing eddy currents in the melt stream. In a preferred embodiment, the regulating device controls the melt stream using at least one stationary magnetic field with a constant polarity, at least one stationary magnetic alternating field or using a multi-poled magnetic travelling field, in such a way that the magnetic field lines transversally penetrate the melt flow across the entire cross section thereof and such that a voltage is induced in the melt stream by the magnetic fields.
