Description

Technical Field

[0001] The present application relates to the field of metallurgical technology, and in particular to a method and device, storage medium, and computer equipment for predicting the life of an inductor of a core furnace. Background Art

[0002] The industrial frequency iron core induction furnace is mainly composed of an induction body, an upper furnace body, a tilting device, a power supply and a control system.

[0003] The working principle of the inductor is similar to that of a step-down transformer. Both the primary coil and the secondary coil are wound on the same magnetic conductor, i.e., the iron core. The annular metal molten groove in the refractory groove of the inductor is equivalent to a short-circuited secondary coil. As a metal conductor in the short-circuited molten groove, it generates current or eddy current under the action of the induced electromotive force. The magnetic flux generated by the eddy current always tries to prevent the magnetic flux in the induction coil from changing. The eddy current generated in the molten groove metal will not stop unless the alternating current applied to the coil stops. The flow of eddy current in the molten groove metal with a certain resistance generates heat, so the metal is heated and melted.

[0028] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0029] In this embodiment, a method for predicting the life of a core furnace inductor is provided. Figure 1 As shown, the method includes:

[0030] Step 101 : collecting initial electrical data of a core furnace inductor through a target device, wherein the initial electrical data includes voltage, current, and power.

[0031] The target device is a device for collecting electrical data of a core furnace inductor, and this application does not limit the target device. Optionally, the target device is a multi-function meter, model DPM8-E3-K1-R / 76D.

[0032] Specifically, the multifunctional instrument is connected to the working circuit of the core furnace, and the electrical data of the core furnace inductor, i.e., the core furnace inductor, is collected through the multifunctional instrument. The electrical data collected for the first time is set as the initial electrical data. The initial electrical data includes data of three dimensions, i.e., voltage, current, and power.

[0033] Step 102: Calculate the initial resistance and initial reactance of the core furnace inductor according to the initial electrical data.

[0034] Specifically, the initial resistance is calculated based on the power and current in the initial electrical data, the initial impedance is calculated based on the voltage and current in the initial electrical data, and further, the corresponding initial reactance is calculated based on the initial resistance and the initial impedance.

[0035] Step 103 , collecting measured electrical data of the core furnace inductor, and collecting the bottom temperature and the side temperature of the core furnace inductor, wherein the measured electrical data includes voltage, current, and power.

[0036] It should be noted that when a core furnace is working, it includes multiple stages, including but not limited to a feeding stage, a melting stage, and a heat preservation stage.

[0037] Specifically, instantaneous electrical data, namely, measured electrical data, are collected at each stage of the core furnace operation. The measured electrical data includes data of multiple dimensions, namely, voltage, current, power, bottom temperature and side temperature.

[0038] Step 104, calculating the resistance and reactance of the core furnace inductor according to the measured electrical data.

[0039] Specifically, the resistance is calculated based on the power and current in the measured electrical data, the impedance is calculated based on the voltage and current in the measured electrical data, and further, the corresponding reactance is calculated based on the above resistance and the above impedance.

[0040] Step 105, determining the state of the core furnace inductor according to the comparison result of the measured electrical data and the initial electrical data.

[0041] Among them, the state of the core furnace inductor is used to indicate whether the core furnace inductor is in a dying state. When the core furnace inductor is in a dying state, the service life of the core furnace inductor will be reset to zero at any time, and attention should be paid to prepare for replacement of the corresponding core furnace inductor.

[0042] By applying the technical solution of this embodiment, the initial electrical data and the measured electrical data of the core furnace inductor can be obtained. According to the comparison result of the measured electrical data and the initial electrical data, it is determined whether the state of the core furnace inductor is a terminal state. When the core furnace inductor is in a terminal state, the service life of the core furnace inductor is reset to zero at any time.

[0043] Optionally, when the core furnace inductor is in a dying state, steps 103-105 are performed at a preset frequency to increase the attention paid to the core furnace inductor in a negative state. Optionally, the preset frequency is once a day.

[0044] In an embodiment of the present application, optionally, the determining of the state of the cored furnace inductor according to the comparison result of the measured electrical data and the initial electrical data in step 105 includes: if the resistance of the measured electrical data is greater than the initial resistance, and the reactance of the measured electrical data is less than the initial reactance, then determining that the cored furnace inductor is in a first state, and the first state is that the melt channel nozzle portion of the cored furnace inductor is blocked or corroded by residue.

[0045] It should be noted that the electrical quantity data of the molten groove part of the core furnace inductor is consistent with the electrical quantity data of the core furnace inductor. Figure 2 The figure shows the cross section of the furnace lining at the melting groove of the cored furnace inductor, where the three elliptical shadow parts are the melting grooves, the two rectangular wireframes are the induction coils, and the trapezoidal shadow part inside the rectangular wireframe is the blocked or eroded part of the melting groove. When the cross-sectional area of ​​the melting groove increases, the resistance of the melting groove decreases; when the gap between the melting groove and the inductor is small, the reactance increases. Therefore, the state of the melting groove part of the cored furnace inductor can be obtained based on the electrical quantity data of the cored furnace inductor. When the melting groove part is in a negative state, it is judged that the life of the corresponding cored furnace inductor has entered a terminal state.

[0046] Specifically, when the resistance obtained according to the measured electrical data measured at any stage is greater than the initial resistance, and the reactance obtained according to the measured electrical data of this stage is less than the initial reactance, it is determined that the cored furnace inductor is in the first state. The first state is that the melt channel nozzle part of the cored furnace inductor is blocked or corroded by residues, and the life of the corresponding cored furnace inductor enters a terminal state.

[0047] In an embodiment of the present application, optionally, the determining of the state of the cored furnace inductor according to the comparison result of the measured electrical data and the initial electrical data in step 105 includes: if the absolute value of the difference between the resistance of the measured electrical data and the initial resistance is less than a first threshold, the absolute value of the difference between the reactance of the measured electrical data and the initial reactance is greater than a second threshold, the second threshold is greater than the first threshold, and the reactance of the measured electrical data is less than the initial reactance, then it is determined that the cored furnace inductor is in the second state, and the second state is erosion of the bottom of the molten groove of the cored furnace inductor.

[0048] The first threshold and the second threshold are obtained based on experience. The first threshold is used to describe that the change between the measured electrical data and the initial electrical data is small. The second threshold is used to describe that the change between the measured electrical data and the initial electrical data is large.

[0049] Specifically, when the resistance obtained according to the measured electrical data measured at any stage changes very little compared to the initial resistance, and the reactance obtained according to the measured electrical data of this stage decreases sharply compared to the initial reactance, it is determined that the cored furnace inductor is in the second state, and the second state is the corrosion of the bottom of the molten groove of the cored furnace inductor, and the corresponding life of the cored furnace inductor enters a terminal state.

[0050] In the embodiment of the present application, optionally, the determining of the state of the cored furnace inductor according to the comparison result of the measured electrical data and the initial electrical data in step 105 includes: if the resistance of the measured electrical data is greater than the initial resistance, the absolute value of the difference between the resistance of the measured electrical data and the initial resistance is greater than a third threshold, the absolute value of the difference between the reactance of the measured electrical data and the initial reactance is less than a fourth threshold, the third threshold is greater than the fourth threshold, and the bottom temperature of the cored furnace inductor is greater than a fifth threshold, then it is determined that the cored furnace inductor is in a third state, and the third state is partial blockage of the cored furnace inductor.

[0051] Among them, the third threshold, the fourth threshold and the fifth threshold are obtained based on experience. The third threshold is used to describe that the measured electrical data has a large change from the initial electrical data. The fourth threshold is used to describe that the measured electrical data has a small change from the initial electrical data. The fifth threshold is used to describe the highest value of the bottom temperature of the core furnace inductor within the normal range. When the bottom temperature of the core furnace inductor is greater than the highest value, it is considered that the bottom temperature of the core furnace inductor is too high.

[0052] Specifically, when the resistance obtained according to the measured electrical data measured at any stage increases sharply compared with the initial resistance, the reactance obtained according to the measured electrical data of this stage changes very little compared with the initial reactance, and the bottom temperature of the core furnace inductor is greater than the fifth threshold, that is, the bottom temperature is too high, then it is determined that the core furnace inductor is in the third state, and the third state is partial blockage of the core furnace inductor, and the corresponding life of the core furnace inductor enters a terminal state.

[0053] In the embodiment of the present application, optionally, the determining of the state of the cored furnace inductor according to the comparison result of the measured electrical data and the initial electrical data in step 105 includes: if the resistance of the measured electrical data is greater than the initial resistance, the reactance of the measured electrical data is greater than the initial reactance, and the side temperature of the inductor is greater than a sixth threshold value, then determining that the cored furnace inductor is in a fourth state, and the fourth state is concentric blockage or eccentric blockage of the cored furnace inductor.

[0054] The sixth threshold is obtained based on experience and is used to describe the highest value of the side temperature of the core furnace inductor within the normal range. When the side temperature of the core furnace inductor is greater than the highest value, it is considered that the side temperature of the core furnace inductor is too high.

[0055] Specifically, when the resistance obtained according to the measured electrical data measured at any stage is greater than the initial resistance, the reactance obtained according to the measured electrical data of this stage is greater than the initial reactance and the side temperature of the core furnace inductor is greater than the sixth threshold, that is, the side temperature is too high, then it is determined that the core furnace inductor is in the fourth state, and the fourth state is concentric blockage or eccentric blockage of the core furnace inductor, and the corresponding life of the core furnace inductor enters a terminal state.

[0056] In the embodiment of the present application, optionally, the method also includes: if the core furnace sensor is in any one of the first state, the second state, the third state and the fourth state, a corresponding alarm message is generated to prompt the staff that the core furnace sensor is in a terminal state.

[0057] This embodiment is used to remind the staff that the core furnace sensor is in a dying state, so that the staff knows that the corresponding core furnace sensor needs to be paid attention to so as to carry out early processing.

[0058] In the embodiment of the present application, optionally, the formula for calculating the initial resistance and initial reactance of the core furnace inductor in step 102 is as follows:

[0059]

[0060] Among them, Z is the initial impedance of the core furnace inductor, U is the voltage in the initial electrical data, I is the current in the initial electrical data, R is the initial resistance of the core furnace inductor, P is the power in the initial electrical data, and X is the initial reactance of the core furnace inductor.

[0061] It is understandable that the manner of calculating the resistance and reactance of the cored furnace inductor according to the measured electrical data in step 104 is the same as the formula for calculating the initial resistance and initial reactance of the cored furnace inductor according to the initial electrical data in step 102 .

[0062] In addition, for ease of understanding, the core furnace inductor of the present application can be composed of an inductor shell, a refractory lining, an iron core, two rectangular coils, a rectangular bushing, a cooling fan, etc. The inductor shell is welded from steel plates, the upper part is a flange connected to the furnace body, and one side is a wind hood. The refractory lining is a furnace lining composed of a layer of asbestos board close to the steel plate and a special refractory material cast. The iron core includes an iron core and an iron yoke, both of which are stacked from cold-rolled silicon steel sheets, with a steel splint on the outside, assembled into a whole by through bolts. The coil is wound with solid flat copper wire wrapped with silicone adhesive tape, and is dipped in paint and dried. The rectangular bushing is bent from non-magnetic stainless steel, and the middle interface is connected as a whole by an insulating plate. A centrifugal fan is installed on each side of the wind hood to ensure good heat dissipation of the coil, the iron core and the rectangular stainless steel bushing. It should be noted that the composition of different core furnace inductors may be different, and the present application does not limit the core furnace inductor. Optionally, the melting groove is designed by computer simulation, the shape and size are optimized, and the flow speed of the molten metal in the melting groove is reasonable, which ensures that the temperature difference of the molten metal between the melting groove and the furnace is small, and avoids the erosion of the melting groove by too fast molten metal flow, thereby ensuring the life of the induction body.

[0063] Optionally, a wooden melting groove mold is used for forming, and the liquid metal is used to start the furnace. After the induction body is formed, a resistance wire is used to gradually bake from low temperature to high temperature to dry and sinter the refractory material of the induction body. After docking with the furnace body, liquid metal is poured into the melting groove, and power is supplied to start the furnace. This can avoid the phenomenon of melting groove fracture and refractory cracking, and ensure the life of the induction body.

[0064] In a specific embodiment, a 45t, 900kw cored induction zinc melting furnace is used as a prediction object, wherein the cored induction zinc melting furnace is the cored furnace in the above embodiment. The cored induction zinc melting furnace has three induction bodies, each with a rated power of 300kw. The cored induction zinc melting furnace is used for zinc alloy production, and the sampling conditions of the electrical parameters of the induction bodies of the cored induction zinc melting furnace are the same. Here, only the 300kw induction body is used as an example for illustration.

[0065] Use the multi-function instrument DPM8-E3-K1-R / 76D to measure the initial electrical data of the inductor for the first time on site, including: power supply U, current I, and active power P.

[0066] According to the U, I, and P values ​​of the initial electrical data, the initial resistance R of the inductor is calculated according to formula (1), and the initial reactance X of the inductor is calculated according to formulas (2) and (3).

[0067]

[0068] Where Z is the initial impedance.

[0069] The instantaneous measured electrical data of the inductor at each stage are measured in real time, including: power supply, current, active power, bottom temperature and side temperature, and the resistance and reactance of the measured electrical data are calculated based on the power supply, current and active power of the measured electrical data. The measured electrical data power supply U, current I, active power P at each stage, as well as the resistance R, impedance Z, reactance X, bottom temperature T1 and side temperature T2 calculated based on the measured electrical data are recorded in Table 1. Figure 3 For example, Figure 3 The table below records the initial resistance and initial reactance of the core furnace inductor, as well as the resistance and reactance obtained based on the measured electrical data. Figure 3 The table forms an RX curve. The slope between two points in the above RX curve can be calculated, and the change trend of R or X can be determined based on the change in slope. Figure 3 The first row in the table is the initial resistance, corresponding to Figure 3 The bottom curve in the table. Figure 3 The second line in the table is the initial reactance, which should be Figure 3 The curve in the second to last row in the table. It should be noted that the initial resistance and initial reactance remain unchanged, so the first measurement using a core furnace is sufficient. Figure 3 The third line in the table is the resistance obtained by measuring the electrical data, which corresponds to Figure 3 The curve corresponding to the highest point on the far right in the table. Figure 3 The fourth line in the table is the reactance obtained from the measured electrical data, which corresponds to Figure 3 The curve corresponding to the second highest point on the far right in the table.
