- a method of this kind is known from WO 03/004198 A2.
- molten steel is poured into a receiving vessel positioned below a tap hole of a steelworks converter, taking into account numerous parameters relevant to the tapping, such as the tilt angle of the steelworks converter, the bricking state of the taphole, the bricking state of the steelworks converter, the batch volume, the tapping time, chemical compositions of the steel and the slag, the temperature of the same, etc., and wherein the tilt angle of the steelworks converter is adjusted in dependence of these parameters.
- the receptacle is located vertically below the tap hole of the converter. The Schmelzenbadspiegel the converter and the receptacle are constantly observed.
- the object of the invention is to further develop a method of the type described above in that the casting can be carried out completely automatically, wherein a casting stream which changes during the progressive tilting of the metallurgical vessel optimally passes into the receiving vessel.
- the height of the bath level in the metallurgical vessel can be determined directly or indirectly; directly by a BadLitemess worn and indirectly in that prior to the determination of the tilt position, the height of the bath level in the metallurgical vessel is determined by calculating the inner volume of the metallurgical vessel and the weight of the melt or the melts, in the latter case preferably before filling the metallurgical vessel the internal volume of the metallurgical vessel is measured by means of a laser scanner.
- the angle between a measuring beam of the measuring device and the bath level and the distance of the bath level are measured by the measuring device.
- a method for tapping steel from a steelworks converter is characterized in that, for casting steel melt from a steelworks converter, the bath level of the slag melt is determined, the tilting position of the metallurgical vessel for casting off the molten steel taking into account the bath level of the molten steel Slag melt is determined such that the bath level of the slag melt for the tilt position of the steelworks converter when tapping the molten steel is located at a safe distance from the converter mouth of the steelworks converter.
- the metallurgical vessel is continuously tilted during the pouring of melt.
- the metallurgical vessel can also be tilted stepwise to avoid overheating of the drive motors.
- a Zugabeschurre is provided, which is tracked in accordance with the changing depending on the progress of pouring tilting angle of the metallurgical vessel pouring stream and / or the trackingconsgefdata.
- a metallurgical vessel equipped with a position measuring device for measuring the tilt angle and an associated control for tilting the metallurgical vessel
- a receiving vessel movable in the direction of the tilting plane of the metallurgical vessel, with a position-measuring device and an associated control for moving the receiving vessel,
- a measuring device for direct or indirect, preferably continuous detection of the bath level of the melt in the metallurgical vessel, and optionally by a
- an addition chute is provided, which is provided with a position measuring device for measuring the position and an associated control for Positioning the Zugabeschurre depending on the position of the pouring stream and / or the position of the receiving vessel is equipped.
- a weighing device for the receptacle is provided.
- Figures 1 to 4 show a schematic representation of different tilting positions of a Stahlwerkkonverters during casting of molten steel and the subsequent casting of slag melt.
- a steelworks converter 1 is mounted in a conventional manner in a support ring 2, which support ring 2 via two diametrically opposed and a rotation axis 3 defining trunnion 4 is tiltable in bearings arranged on the foundation, by means of an electric drive, not shown.
- a ladle carriage 5 for receiving molten steel 6 in a pan 7 and further also a slag 8 for receiving slag melt 9 in a slag bucket 10 in the symmetry tilt plane of the steel mill converter 1 movable, and also in each case by means of an electric drive ,
- a melt bath level measuring device 11 On the side of the steel mill converter 1, a melt bath level measuring device 11 provided with a cooling device is provided, and likewise in the symmetry tilting plane. With this measuring device 11, the interior of the Stahlwerkskonverters 1 anvinstrument, and it is the Schmelzenbadaptproof love 12, as soon as the converter mouth 13 of the Stahlwerkskonverters 1 is directed against the measuring device 11 when tilting the Stahlwerkskonverters 1, by measuring the angle 14 between a Measuring beam 15 of the measuring device 11 and the bath mirror 16 and the removal of the bath mirror 16 of the measuring device 11.
- the measuring device 11 may, for example, by means of a laser beam or radar work.
- the tilting position of the steelworks converter 1 can be determined by means of a position measuring device which is usually present in steel mills. Likewise, the positions of the movable below the steelworks converter receptacles, so the pan 7 and the slag pan 10, by means of conventional, not shown, position measuring devices detected. Both the tilt drive of the Stahlwerkskonverter 1 as well as the traction drive of the ladle truck 5 and also the slag carriage 8 are equipped with controls for accurate positioning.
- the current state of the bath level 16 as a function of the tilt angle of the steelworks converter 1 on the basis of the current converter geometry (here the Ausmautationsschreib meant) and the batch size can be calculated.
- the current amount of the cast-off molten steel 6 is continuously detected by means of weighing devices for weighing the total weight of the receptacles 7 during tapping.
- the current level of the bath level 16 can thus be continuously calculated.
- the automatic pouring process is as follows: It is started by the operator.
- the steelworks converter 1 is automatically tilted towards pouring molten steel 6, wherein the current level of the bath 16 is continuously detected, in one of the two methods described above either from the distance of the bath level 16 of the measuring device 11 and from the angle 14, the Badador 16 with the measuring beam 15 of the measuring device 11 includes, or by Volums- and weight measurements.
- a maximum possible bath level 16 results from the lowest edge 13 'of the converter mouth 13.
- a table with the data for the maximum bath level 16 as a function of the tilt angle of the steel mill converter 1 is stored in the control system and can be adapted to the installation in the course of commissioning.
- the maximum possible bath level is reduced by an adjustable value and given to the pouring control as the desired bath level. In other words, a safety distance of the bath level 16 from the deepest edge 13 'of the converter mouth 13 is maintained.
- the tilting position of the steel mill converter 1, in which steel molten steel 6 to be discharged from the tap hole 17 in the form of a pouring stream 18, is calculated. This results in a certain position of the resulting from the festgestllten tilting pouring stream 18, which position causes the positioning of Aufnahnmegefäßes 7 for receiving the molten steel 6, namely computer controlled. Then the steelworks converter 1 is tilted into the position tapping start (see Fig. 1), the tilt angle is in the illustrated embodiment at 51 °.
- the tap hole 17 is closed, for example with a closure device with a closure body, which can be brought from a waiting position into a closed position, as described in EP 1 054 068 A2.
- the relationship between the tilt angle of the steel mill converter 1 and the position of the pouring stream 18 or the position of the ladle carriage 5 is permanently stored in the automation system and is adapted to the installation.
- 5 additive can be introduced into the pan 7 by means of a Zugabeschurre 19 as a function of the converter tilt angle of the steel mill converter 1 and in dependence on the position of the ladder carriage.
- the position of the addition chute 19 is also detected by means of a continuous position measuring system and automatically positioned according to the position of the receiving vessel 7.
- the addition of aggregate is started either automatically or by the operator.
- the steelworks converter 1 is now continuously or stepwise tipped according to the scheme deposited in the automation system until residual steel is detected by the slag detection system or the maximum pouring tilt angle (see Fig. 4, tilt angle - 150 °) is reached. After reaching the maximum tilt angle or residual steel detection, the steelworks converter is automatically raised again.
