Definitions
- the invention relates to a device for detecting a delivery rate, with which a liquid material from a pivotable starting vessel is filled into a target metallurgical vessel, and a corresponding method.
- an automatic device for managing the charge of molten material or scrap in dependence on the energy supplied to the bath and an apparatus for measuring the supplied melt material associated with the automatic management device including a device for weighing the furnace, its contents and possibly further provided on the same load-bearing components.
- the indirect measurement method is based on a geometric detection of the liquid metal level within the furnace, which data can be converted into volume data, which then, with knowledge of the specific gravity of the liquid metal, allows a conclusion about the weight of the liquid metal received within the furnace.
- the indirect measuring method is performed only when the furnace is filled with the liquid metal to determine the level of the liquid metal within the furnace as explained. If an erosion effect should occur on the inner lining of the furnace as a result of an interaction with the liquid metal, the internal volume of the furnace may change, resulting in disadvantageously large inaccuracies for the indirect measuring method.
- EP 2 061 612 B1 discloses a method for pouring melt from a tiltable metallurgical vessel and a corresponding system for carrying out this method.
- a pouring of melt from a tiltable metallurgical vessel into a receiving vessel can be carried out completely automatically, because the position of a melt-pouring stream, which results from a determined tilting position of the metallurgical vessel, is determined automatically, with subsequent dependence the determined position of this pouring stream is brought into position the receiving vessel to receive the melt dumped from the metallurgical vessel.
- the above-described prior art is subject to the disadvantage that the feedstock to which an oven is fed can either be processed only in solid form, or that in the measuring methods for the targeted Charging this feed requires a complex weighting of equipment components including a lower vessel for a ladle is required. Accordingly, the invention has for its object to detect the delivery rate for a liquid material, with which the liquid material is filled into a target metallurgical vessel, by simple means and based on which also set or regulate exactly.
- the above object is achieved by a device having the features specified in claim 1 and by a method according to claim 10.
- An apparatus is for detecting a delivery rate at which a liquid material from a pivotable exit vessel is filled into a target metallurgical vessel, and comprises means for determining an amount of liquid material filled in the exit vessel and means for detecting an amount of liquid material that is discharged by pivoting the output vessel in the direction of the target vessel.
- a method according to the present invention is for detecting a delivery rate of a liquid material, with which the liquid material is filled from a pivotable starting vessel into a target metallurgical vessel, and is characterized by the following steps:
- this amount of liquid material is the delivery rate at which the liquid material is introduced into the metallurgical target vessel. This delivery rate can be detected either volumetrically, for example by means of suitable scanner devices or the like. With knowledge of a predetermined specific density of the liquid material, it is then possible to convert the recorded volume of the liquid material into a corresponding weight.
- the amount of liquid material which is discharged from the starting vessel in the direction of the target vessel is detected directly gravimetrically, for example by a weighing device or the like, which may be in the form of a weight measuring cell.
- the liquid materials whose delivery rate is detected by means of a device or a method according to the present invention can generally be liquid substances, for example pig iron, slag or the like, which may have a high temperature and optionally a low viscosity ,

- the addition channels it is possible for either the addition channels to open directly into the metallurgical vessel, or to the addition channels for further aids, for example a conveyor trough or the like, through which transport of the liquid material into the destination vessel is ensured.
- the means by which the amount of liquid material is determined in the starting vessel comprise a first scanner device.
- a scanner device By means of such a scanner device, it is possible to scan the starting vessel and its geometry, namely both when the starting vessel is still empty and when the liquid material is filled in the starting vessel.
- the scanning of the starting vessel in the empty state is advantageous, in particular for determining a possible receiving volume of the starting vessel, because in this way a precise state of an inner wall of the starting vessel can be determined or determined. This is particularly advantageous when the starting vessel is a ladle, the inner wall of which generally has a lining which may be subjected to erosive wear as a result of contact with hot molten metal.
- the starting vessel is first scanned in the empty state by the first scanner device, i. if it contains no liquid material.
- the first scanner device i. if it contains no liquid material.

- the means with which the amount of liquid material discharged by pivoting the starting vessel in the direction of the target vessel is detected may comprise a displacement measuring device or a position measuring device. This makes it possible to determine a tilting movement, with which the output vessel is pivoted in the direction of the target vessel, namely in terms of both a tilt angle and a tilting speed for the output vessel.

- a tilting speed for the starting vessel in step (ii) is selected or regulated such that the delivery rate at which the liquid material exits the starting vessel in the direction of the target vessel is substantially constant. This makes it possible for the liquid material to be introduced into the metallurgical target vessel at a predetermined delivery rate.
- a decrease in the level of liquid material within the exit vessel, which decreases as the liquid material exits the exit vessel, is appropriately compensated to achieve a desired delivery rate.
- the apparatus according to the present invention may be provided in an oven for steelmaking either as original equipment, or may be retrofitted.
- the essential components of the device according to the invention are constituted by the means for determining an amount of liquid material filled in the starting vessel and the means for detecting a quantity of liquid material discharged by pivoting the starting vessel towards the target vessel , educated.

- the ladle 4 can be pivoted in the direction of the furnace 6.
- the ladle 4 is shown in an initial position (FIG. 2), in an intermediate position (FIG. 3) and in an end position (FIG. 4).
- a pivoting of the ladle 4 in the direction of the furnace 6 is used for the purpose that a liquid material, such as molten pig iron, is discharged from the ladle 4 in the direction of the furnace 6 and preferably at a predetermined delivery rate in the oven 6 is filled.
- a Pfannenabsetzstand 7 Adjacent to the oven 6 is a Pfannenabsetzstand 7 is positioned, which has a pair of support arms 8 which are pivotable about a horizontal axis A.
- Blind grooves 8s (FIG. 2) are formed at each free end of the holding arms 8.
- Guide pins 4z ( Figure 2) are mounted on opposite sides of the ladle respectively. Thus, it is possible to mount the ladle 4 between the support arms 8 by the guide pins 4z are suspended in the blind grooves 8s of the two support arms 8.
- the Pfannenabsetzstand 7 has at least one hydraulic cylinder 10 which is articulated on one of the two retaining arms 8.
- each of the two support arms 8 is associated with a separate hydraulic cylinder 10, which can not be seen in the side views of the drawing.
- a Zufaberinne 12 is arranged, whose course is inclined in the direction of the furnace 6 downwards. Subsequent to the feed grooves 12, a conveyor trough 13 is provided which leads into the oven 6.

- a sensor 26 for Wegmesser written By means of this sensor 26, it is possible to determine an exact position of the holding arms 8, and thus also the pouring ladle 4 suspended therein. Based on this, it is possible to measure a tilting movement of the ladle 4, both in terms of a tilt angle and a tilting speed relative to the furnace 6.
- the invention now works as follows:
- the ladle 4 Before the processing of a batch of liquid material 2, for example in the form of pig iron, the ladle 4 is first scanned in the empty state by means of the scanner device 20 in order to determine the inner volume of the ladle 4 exactly. Subsequently, the liquid material 2 is filled into the ladle 4, wherein by means of the scanner device 20 then the filling level for the liquid material 2 is determined within the ladle. Then, the ladle 4, starting from its initial position shown in FIG. 2, tilted about the axis A in the direction of the furnace 6, and passes through an intermediate position (Fig. 3) in its end position (Fig. 4). As already explained, the liquid material 2 flows out of the opening 5 of the pouring ladle 4 into the feed channel 12, and subsequently enters the oven 6.
- the speed with which the ladle 4 is tilted about the axis A in the direction of the oven 6 is, taking into account the filling level or the filling weight of the liquid material which is received in the ladle 4, calculated in advance, and suitably adjusted by driving the hydraulic cylinder 10.
- the means 24 may also include a first weighing device 22, which may be provided as an alternative or in addition to the scanner device 20.
- the first weighing device 22 is integrated into the Pfannenabsetzstand 7, and allows a determination of the weight of the suspended in the support arms 8 ladle 4, namely both in its initial position, as well as during pivoting about the axis A. Taking into account the change in weight of the ladle 4, which results in their pivoting about the axis A due to an exit of the liquid material 2, the amount of liquid material which is filled into the furnace 6, ie the delivery rate can be determined by calculation.
- the first weighing device 22 it is also possible to determine the weight of the liquid material 2 filled in the ladle 4 when it is in its initial position according to FIG. This is done in a simple manner by measuring the weight of the ladle 4 in the empty state, and then in the filled state together with the liquid material 2. In that regard, the first weighing device 22 also forms part of the means 18th
- the means 24 may comprise a second scanner device 28 with which the filling level 16 for the liquid material 2 within the feed channels 12 is determined.
- FIG. 7 shows a simplified cross-sectional view of the feed grooves 12, and illustrates that the second scanner device 28 is positioned above the feed grooves 12, for example, to scan the feed grooves 12 and thereby fill level 12 for the liquid Material 2 to capture.
- the access grooves 12 it may be pointed out with regard to the access grooves 12 that their geometry (in a plane orthogonal to the flow direction of the liquid material) and angles of inclination in the direction of the furnace 6 are known.
- the means 24, in addition or as an alternative to the second scanner device 28, comprise a second weighing device 30, which in the illustration of FIG. 7 is shown only in a symbolically simplified manner.
- the weight in the feed channel 12 can be determined continuously when, during a pivoting of the ladle 4 about the axis A, the liquid material 2 exits the pouring ladle 4 into the feed channel 12.
- the means 24, in addition or as an alternative to the second scanner device 28 and the second weighing device 30, comprise measuring loops 32 which are made into the refractory (FF) material from which the feed channels 12 are made , are embedded (see Fig. 7). If the feed grooves 12 are traversed by liquid material in the form of pig iron, 32 electric fields are induced in the measuring loops, by means of which then the filling height 16, which is set for the pig iron within the feed grooves 12, can be determined.
- FF refractory
- the ladle 4 hangs on a crane 34.
- Fig. 8 shows a part of a furnace 6 of FIG. 1.
- the ladle 4 can be tilted controlled or pivoted in the direction of the furnace 6, in the same way as in Fig. 3 and Fig. 4 shown and explained, so that as a result liquid material 2 is poured from the ladle 4 through the Zufaberinne 12 in the oven 6.
- a third weighing device 36 may be integrated, by means of which a change in weight for the ladle 4 is determined when it is pivoted in the direction of the furnace 6 while liquid material 2 emerges from the ladle 4.
- the measured weight change for the ladle 4 is, in the same way as in the measurement with the first weighing device 22, a measure of the flow rate in the form of a mass flow, with which the liquid material 2 is introduced into the furnace 6.
- the above-explained scanner device 28, the weighing devices 22, 30, 36 and the measuring loops 32 can be used alternatively or cumulatively, in order to determine the delivery rate at which the liquid material 2 is filled in the oven 6. In a cumulative use of these elements improved accuracy in terms of detection and adjustment of the delivery rate for the liquid material 2 is ensured.
- the device 1 also comprises a controller 3, which, for example in FIG. 2, is indicated only symbolically for the sake of simplicity. All of the mentioned scanner devices, weighing devices and position sensors or sensors are connected to the controller 3 via data lines (not shown), so that their signals can be processed in the controller 3. On the basis of this, a suitable activation or regulation of the hydraulic cylinder 10 for setting a desired tilting speed for the ladle 4 is possible because the hydraulic cylinder 10 is likewise connected to the controller 3. As a result, a predetermined delivery rate can be achieved thereby, with which the liquid material 2 is introduced into the oven 6.
