All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Embodiments of an electrode position detecting apparatus for a submerged arc furnace and a submerged arc furnace device according to the present invention will be described below with reference to the accompanying drawings.
In an embodiment of the electrode position detection apparatus for a submerged arc furnace provided by the present invention, referring to fig. 1, the electrode position detection apparatus includes a controller and a plurality of array electromagnetic sensors 20. The plurality of array electromagnetic sensors 20 correspond to the plurality of electrodes 11 in the submerged arc furnace 10, respectively. Each array electromagnetic sensor 20 is disposed outside the submerged arc furnace 10 opposite to its corresponding electrode 11 for detecting the magnetic induction intensity of the magnetic field generated by its corresponding electrode. In fig. 1, 3 electrodes 11 are provided in the submerged arc furnace 10, and accordingly, the electrode position detecting means includes 3 array electromagnetic sensors 20; the 3 array electromagnetic sensors 20 are disposed at regular intervals on the peripheral side of the submerged arc furnace 10, corresponding to the 3 electrodes 11 in the submerged arc furnace 10, that is, the three array electromagnetic sensors 20 are disposed at an angle of 120 degrees with respect to each other around the submerged arc furnace 10 as the center of a circle.
Referring to fig. 1 and 2, each of the array electromagnetic sensors 20 includes a plurality of electromagnetic sensor groups 21, and each of the electromagnetic sensor groups 21 is configured to detect the magnetic induction intensity of the magnetic field at three-dimensional space coordinates. Specifically, each array electromagnetic sensor 20 may include 7 electromagnetic sensor groups 21. The plurality of electromagnetic sensor groups 21 of each array electromagnetic sensor 20 may be vertically and sequentially arranged at intervals; in each array electromagnetic sensor 20, the pitch between adjacent electromagnetic sensor groups 21 may be set at 100 mm.
The controller is configured to receive magnetic induction intensity information detected by the plurality of electromagnetic sensor groups 21 in each array electromagnetic sensor 20, and determine the insertion depth of the electrode 11 corresponding to the array electromagnetic sensor 20 according to the detection results of the different electromagnetic sensor groups 21.
When the submerged arc furnace works, the furnace side transformer converts the high voltage and low current of the primary side into the high current and low voltage of the secondary side, the current input into the submerged arc furnace 10 by the electrode 11 can reach tens to hundreds of kiloamperes, and the strong current can generate a strong magnetic field outside the submerged arc furnace 10.
In the present embodiment, by providing the array electromagnetic sensor 20 on the outside of the submerged arc furnace 10, and the array electromagnetic sensor 20 includes a plurality of electromagnetic sensor groups 21, by means of the electromagnetic sensor groups 21 provided, the magnetic induction intensity of the magnetic field at the position where the electromagnetic sensor groups 21 are located can be detected.
From the following equation (1), the following equation (2) can be derived, and from this equation (2), it is known that the distribution of the magnetic field outside the submerged arc furnace 10 is related to the electrode position and the current level.
Figure BDA0004001686960000041
Figure BDA0004001686960000042
In the above formula (1) and formula (2), I is the current on the electrode 11; l is an integral path; dl is the tiny line element of the current;
Figure BDA0004001686960000043
a unit vector pointing to a field point to be solved for the current element; mu (mu) 0 Is vacuum permeability, its value is 4pi×10 -7 Tm/A。
From the above analysis, the magnetic induction of the magnetic field outside the submerged arc furnace 10 is related to the position of the electrode 11, i.e., the insertion depth of the electrode 11 into the submerged arc furnace 10. When the insertion depth of the electrode 11 is changed, the induction intensity of the magnetic field is also changed, as shown in fig. 4. Therefore, in the present embodiment, the position of the electrode 11, that is, the insertion depth of the electrode 11 can be theoretically determined by analysis and data processing by the magnetic induction intensities detected by the plurality of electromagnetic sensor groups 21.
In the case of the submerged arc furnace 10, in actual operation, there are many electric devices disposed around it, which interfere with the magnetic field generated by the electrode 11 outside the submerged arc furnace 10, so that the insertion depth of the electrode 11 into the submerged arc furnace 10 cannot be accurately determined by detecting the magnetic induction intensity outside the submerged arc furnace 10. For this reason, in the present embodiment, the type of electromagnetic sensor provided outside the submerged arc furnace 10 is determined as the array electromagnetic sensor 20, the magnetic induction intensity of the magnetic field is detected by the plurality of electromagnetic sensor groups 21 included in each array electromagnetic sensor 20, the detection results of the plurality of magnetic induction intensities are obtained, the controller finally determines the magnetic induction intensity of the magnetic field from the difference between the detection results of the magnetic induction intensities, and then the insertion depth of the corresponding electrode 11 in the submerged arc furnace 10 is obtained through data processing. By doing so, the influence of various disturbances on the magnetic field can be eliminated or improved, and the obtained data of the magnetic induction intensity can be made more accurate, so that the insertion depth of the electrode 11 in the submerged arc furnace 10 can be determined more accurately.
Specifically, in one embodiment of the electrode position detecting apparatus, the controller determines the insertion depth of the electrode according to the following formula (3):
z(B)＝aB+b (3)
wherein z is the insertion depth of the electrode; a. b is a constant, determined experimentally; b is the magnetic induction intensity obtained by detection of the corresponding array electromagnetic sensors.
In this embodiment, the values of a and b are specifically related to the geometry of the submerged arc furnace 10, the position where the electromagnetic sensor group 21 is placed, the magnetic field interference outside the submerged arc furnace 10, and the distribution of the carbon steel furnace shell, and after these parameters and the environmental quantities are determined, the values of a and b can be calibrated according to the insertion depth of the electrode 11 and the magnetic induction intensity detected by the corresponding array electromagnetic sensor 20 in the experimental results through several experiments, that is, the relationship between the insertion depth of the electrode 11 and the magnetic induction intensity detected by the corresponding array electromagnetic sensor 20 is determined, as shown in fig. 4.
After the values of a and b are determined, the position of the electrode 11, that is, the insertion depth of the electrode 11 into the submerged arc furnace 10 can be determined by detecting the magnetic induction intensity of the magnetic field obtained by the corresponding array electromagnetic sensors 20 during the operation of the submerged arc furnace 10.
In one embodiment of the electrode position detecting apparatus, the magnetic induction intensity B detected by the array electromagnetic sensor 20 is obtained according to the following formula (4):
B＝[(B x1 －B y1 )+(B x2 －B y2 )+……+(B xn －B yn )] / n (4)
wherein B is x1 And B y1 The magnetic induction intensity detected by the two electromagnetic sensor groups 21 of the 1 st group in the array electromagnetic sensor 20 is represented by B x2 And B y2 The magnetic induction intensity detected by the two electromagnetic sensor groups 21 of the group 2 in the array electromagnetic sensor 20 is represented by B xn And B yn The magnetic induction intensity detected by the two electromagnetic sensor groups 21 of the nth group in the array electromagnetic sensor 20 is shown.
In this embodiment, among the plurality of electromagnetic sensor groups 21 of one array electromagnetic sensor 20, n groups of 2 electromagnetic sensor groups 21 are selected, the difference in magnetic induction intensity detected by the two electromagnetic sensor groups 21 of each group is calculated, and then the average value of the n groups is taken and is regarded as the magnetic induction intensity of the magnetic field generated by the electrode 11 detected by the array electromagnetic sensor 20 as a whole.
In the above embodiment, the two electromagnetic sensor groups 21 in the 1 st group, the 2 nd group and the n th group may be selected in advance or may be determined randomly. For example, taking an array electromagnetic sensor 20 including 7 electromagnetic sensor groups 21, and the 7 electromagnetic sensor groups 21 being arranged at vertical intervals as an example, the magnetic induction intensity B detected by the array electromagnetic sensor 20 as a whole can be determined according to the following formula (5):
Figure BDA0004001686960000061
that is, for one array electromagnetic sensor 20, the difference between the magnetic inductances of the magnetic fields detected by the 7 th electromagnetic sensor group 21 and the 3 rd electromagnetic sensor group 21 is calculated, the difference between the magnetic inductances of the magnetic fields detected by the 6 th electromagnetic sensor group 21 and the 2 nd electromagnetic sensor group 21 is calculated, the difference between the magnetic inductances of the magnetic fields detected by the 5 th electromagnetic sensor group 21 and the 1 st electromagnetic sensor group 21 is calculated, and the average value of the three differences is taken as the detection result of the array electromagnetic sensor 20 as a whole, that is, the magnetic inductances of the magnetic fields generated by the corresponding electrodes 11 outside the submerged arc furnace 10. The magnetic induction intensity value obtained by the calculation and the processing can eliminate or improve the interference of other electric equipment and the like on the magnetic field, and the insertion depth of the electrode 11 obtained by the calculation is more accurate.
In one embodiment of the electrode position detecting apparatus, as shown in fig. 3, each electromagnetic sensor group 21 includes a first coil 211, a second coil 212, and a third coil 213; the first coil 211, the second coil 212, and the third coil 213 have a common winding center, and planes in which winding directions of the first coil 211, the second coil 212, and the third coil 213 are located are perpendicular to each other. Specifically, the diameters of the first coil 211, the second coil 212, and the third coil 213 may be set to 40 mm.
In this embodiment, referring to the direction shown in fig. 3, the first coil 211 is wound in a clockwise or counterclockwise direction in a horizontal direction, that is, the circumference of the first coil 211 is in the horizontal direction; the second coil 212 is wound in a clockwise or counterclockwise direction in the first vertical plane, that is, the circumference of the second coil 212 is in the first vertical plane; the third coil 213 is wound in a clockwise or counterclockwise direction in the second vertical plane, that is, the circumference of the second coil 223 is in the second vertical plane. Since the first vertical surface and the second vertical surface are perpendicular to each other, the circumferential directions of the first coil 211, the second coil 212, and the third coil 213 are perpendicular to each other. With this structure, the electromagnetic sensor group 21 composed of the first coil 211, the second coil 212, and the third coil 213 can detect the magnetic induction intensity of the magnetic field in different directions (x direction, y direction, and z direction perpendicular to each other) in three-dimensional coordinates.
In the present embodiment, of course, the magnetic induction intensity detected by each electromagnetic sensor group 21 is a vector value in three-dimensional coordinates, and the difference between the detection results of different electromagnetic sensor groups 21 from which the insertion depth of the electrode 11 is determined is also a vector value in three-dimensional coordinates.
In one embodiment of the electrode position detection apparatus, the controller further comprises a visual output module for demonstrating the insertion depth of the electrode 11 in the submerged arc furnace 10 in a manner of displaying an image. In particular, the carrier of the visual output module may be a display that displays a presentation image of the electrode 11 in the submerged arc furnace 10. The displayed demonstration image can be a static image or a dynamic video.
The electrode position detecting device for the submerged arc furnace provided by the embodiment of the invention correspondingly detects the magnetic induction intensity of the magnetic field generated by the plurality of electrodes 11 in the submerged arc furnace 10 by arranging the plurality of array electromagnetic sensors 20 on the outer side of the submerged arc furnace 10. Specifically, by providing a plurality of electromagnetic sensor groups 21 in each array electromagnetic sensor 20, each array electromagnetic sensor 20 can obtain a plurality of detection results of magnetic induction intensities by means of the provided electromagnetic sensor groups 21, and the controller finally determines the magnetic induction intensity of the magnetic field from the difference between the detection results of the magnetic induction intensities, and then obtains the insertion depth of the corresponding electrode 11 in the submerged arc furnace 10 by data processing.
