A measurement system and method for the roll gap of a continuous casting machine.

Abstract

This invention discloses a measurement system and method for the roll gap of a continuous casting machine. The measurement system includes a main body, two detection components, and two oscillating components. When the first end of the oscillating component contacts the roll to be measured, the oscillating component rotates, driving the detection end to move, so that the detection component obtains a displacement, thereby realizing the measurement of the roll gap. This reduces the sources of error in the measurement process and provides reliable data support for the precise control of the continuous casting machine. It does not require an additional power unit or a complicated operation process, simplifies the measurement operation, improves the measurement efficiency, and can quickly respond to changes in the roll gap during the continuous casting machine production process. When the outer arc roll of the casting machine is offset due to bearing seat damage, cylinder setting deviation, etc., it can still be detected, avoiding measurement errors caused by changes in the position of the roll. The overall structure is compact, especially in the face of complex measurement environments, further reducing the space occupied for measurement.

Description

Technical Field

[0001] This application relates to the field of continuous casting machine roll gap control technology, and in particular to a measurement system and method for continuous casting machine roll gap. Background Technology

[0002] A slab continuous casting machine is a device that solidifies molten steel and die-casts it into steel billets. The roll gap control accuracy of the continuous casting machine directly affects the product quality of the cast billets. The roll gap is a crucial production process parameter in the continuous casting process. In actual operation, poor roll gap control accuracy can easily lead to serious quality defects such as bulging, central porosity, segregation, and wedge-shaped billets in batches. In severe cases, it can also cause accidents such as billet stagnation and steel leakage, resulting in huge economic losses.

[0003] Currently, offline casting machine roll gap detectors are mostly used for roll gap detection. These detectors have many measurement parameters and powerful functions, but during installation, production time needs to be organized separately to complete the replacement of the dummy head. After the measurement is completed, the dummy head needs to be replaced again, which takes a long time each time and affects output. The measurement frequency is usually low, and the status of the casting machine between two measurement intervals cannot be controlled.

[0004] Another type of online roll gap meter can detect roll gaps every time casting begins, allowing for high measurement frequency. However, online roll gap meters are limited by the space constraints imposed by the casting machine structure and the ingot dummy bar structure, requiring the roll gap meter to be small in size, high in precision, and easy to maintain. Currently, online roll gap meters with a pendulum-type structure are relatively large, which is not conducive to meeting the roll gap measurement needs at the edge of the casting roll and lacks scalability. Summary of the Invention

[0005] In view of the deficiencies in the prior art, this application provides a measurement system and method for the roll gap of a continuous casting machine, so as to solve the problems of large measurement error, complicated operation and large space occupation of the casting roll in the prior art.

[0006] The above-mentioned objectives of this application are mainly achieved through the following technical solutions:

[0007] A measurement system for the roll gap of a continuous casting machine, the measurement system comprising:

[0008] Main components;

[0009] Two detection elements are fixedly mounted on the main body at intervals. Each detection element has a detection end that can reciprocate in a first direction so that the detection element obtains the displacement of the detection end.

[0010] Two oscillating members are movably connected to the main body at intervals and are arranged correspondingly to the two detection members. The middle part of the oscillating member is rotatably connected to the main body. The oscillating member has a first end for extending to the circumferential surface of the roller to be tested and a second end for connecting to the detection end. When the two first ends extend to the circumferential surface of the two rollers to be tested, the two oscillating members rotate respectively, and the second ends drive the two detection ends to move respectively until the two detection members obtain displacement.

[0011] In an optional embodiment, the measuring system includes two elastic elements, one end of which is fixedly connected to the main body, and the other end of which is connected to the second end. The rotation of the oscillating element can cause the elastic elements to deform, and the deformation restoring force of the elastic elements can drive the oscillating element to rotate and reset.

[0012] In an optional embodiment, the two detection elements are symmetrically arranged on the main body, and the two swing elements are symmetrically arranged on the main body.

[0013] In an optional embodiment, the detection element and the swing element are respectively connected to the main body via a base.

[0014] In an optional embodiment, the main body is provided with a sealed space, and the sealed space is provided with a controller and a power supply unit respectively connected to the detection element. The controller is used to read and process the displacement, and the power supply unit can supply power to the controller and the detection element respectively.

[0015] In an optional embodiment, the main body is provided with a partition, one side of which encloses the main body to form the sealed space, and one side of the detection component with a detection end penetrates the partition and extends outside the sealed space.

[0016] In an optional embodiment, the first end and the second end of the swing member are respectively provided with contact wheels.

[0017] In an optional embodiment, the first end and the second end of the swing member are respectively designed as arcs, and the first end and the second end are respectively provided with a wear-resistant coating.

[0018] Based on the same inventive concept, this application also provides a method for measuring the roll gap of a continuous casting machine, wherein the measurement method is applied to the above-mentioned measurement system, and the measurement method includes:

[0019] Arrange the main body component at the two rollers to be tested;

[0020] Move the main body until the first ends of the two swing members respectively contact the circumferential surfaces of the two rollers, the swing members rotate synchronously, and the second end of the swing members drives the detection end of the detection member to move;

[0021] Two displacement data points are obtained through the detection device, and the roll gap data between the rollers is calculated based on the displacement data.

[0022] In an optional implementation, when calculating the roll gap data between the rollers,

[0023] Obtain the two displacements S1 and S2;

[0024] Obtain: The distance L from the first end of a oscillating component to the center of rotation of the oscillating component. 1a The distance L from the second end to the center of rotation of the oscillating component 2a The distance r between the center point of the first end and the contact point with the roller. 1a The distance r between the center point of the second end and the contact point with the detection end 2a ;

[0025] Obtain: The distance L from the first end of the other oscillating component to the center of rotation of the oscillating component. 1b The distance L from the second end to the center of rotation of the oscillating component 2b The distance r between the center point of the first end and the contact point with the roller. 1b The distance r between the center point of the second end and the contact point with the detection end 2b ;

[0026] Obtain: the distance H between the rotation centers of the two oscillating components;

[0027] The rotation angles ∠θ1 and ∠θ2 of the two oscillating components are obtained using the following formulas:

[0028] s1=L 2a ×sinθ1,s2=L 2b ×sinθ2;

[0029] The amount of pressure H at the first end of the two oscillating members is obtained using the following formula. 1a H 1b :

[0030] H 1a =L 1a -L 1a ×cosθ1,H 1b =L 1b -L 1b ×cosθ2;

[0031] The roll gap data G between the two rolls is obtained using the following formula:

[0032] G = L 1a +r 1a -H 1a +H+L 1b +r 1b -H 1b .

[0033] Compared with the prior art, the advantages of this application are:

[0034] The measurement system in this application is used for measuring the roll gap of a continuous casting machine. The measurement system includes a main body, two detection elements, and two swing elements, which are fixedly mounted on the main body at intervals. Each detection element has a detection end that can reciprocate in a first direction so that the detection element obtains the displacement of the detection end.

[0035] The oscillating members are rotatably connected to the main body and arranged correspondingly to the two detection members. The oscillating members have a first end for extending to the circumferential surface of the roller to be tested and a second end for connecting to the detection end. When the two first ends extend to the circumferential surface of the two rollers to be tested, the two oscillating members rotate respectively, and the second ends drive the two detection ends to move respectively until the two detection members obtain displacement respectively.

[0036] The detection end of the detection component can reciprocate in a first direction to acquire the displacement. Oscillating components are movably connected to the main body at intervals and are arranged corresponding to the detection component. The first end of the oscillating component extends to the circumferential surface of the roller to be tested, and the second end is connected to the detection end. When the first end of the oscillating component contacts the roller to be tested, the oscillating component rotates, causing the detection end to move, thus enabling the detection component to acquire the displacement and thereby achieving the measurement of the roller gap.

[0037] By extending the first end of the oscillating component directly to the circumference of the roll to be tested, the actual position of the roll can be accurately sensed, reducing the sources of error in the measurement process. The detection end of the detection component moves under the drive of the oscillating component, directly obtaining the displacement, which can accurately reflect the change of the roll gap and provide reliable data support for the precise control of the continuous casting machine.

[0038] Through reasonable design and connection, the detection and oscillating components ensure stable and reliable relative movement between the components during measurement, reduce measurement errors caused by mechanical vibration or loosening, and improve the long-term working stability of the system.

[0039] The rotation of the oscillating component can automatically drive the detection end to move, without the need for additional power devices or complicated operating procedures. This simplifies the measurement operation, improves measurement efficiency, and enables rapid response to changes in the roll gap during the continuous casting machine production process, providing timely measurement data.

[0040] Because the detection end can reciprocate in the first direction and the oscillating component can rotate flexibly, the system has the ability to measure continuously and monitor the changes in the roll gap in real time. This provides continuous and real-time measurement signals for the automated control of the continuous casting machine, which helps to optimize the continuous casting process and improve product quality.

[0041] By adjusting parameters such as the length or angle of the oscillating component, this measurement system can adapt to continuous casting machine rolls of different diameters and spacings, exhibiting excellent versatility and adaptability. It can meet the roll gap measurement needs of various continuous casting machine models and production conditions, reducing equipment procurement and maintenance costs for enterprises. It reduces the frequency and complexity of manual measurement, lowers errors and risks associated with manual operation, saves labor costs, and improves production efficiency, demonstrating good cost-effectiveness in the long run. The oscillating component can measure the reduction of the upper and lower casting rolls separately. Even when the outer arc roll of the casting machine shifts due to bearing damage or cylinder setting deviations, it can still be detected. The obtained measurement results can be analyzed through measurement trends and values ​​to make judgments and provide maintenance suggestions, avoiding measurement errors caused by changes in roll position. The overall structure is compact, further reducing the space occupied, especially in complex measurement environments. Attached Figure Description

Detailed Implementation

[0048] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are merely for describing exemplary embodiments of the invention. However, the invention can be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0049] like Figure 1 , Figure 2 As shown, Figure 1 This is a cross-sectional view of the measurement system provided in an embodiment of this application. Figure 2 A side view of a measurement system provided in an embodiment of this application; a measurement system for the roll gap of a continuous casting machine, the measurement system comprising a main body 100, a detection component 200, and a swing component 300, wherein:

[0050] like Figure 1 , Figure 2 As shown, the main body 100 serves as the supporting frame for the entire measurement system, fixing and connecting other components. The two detection elements 200 and the two swing elements 300 are fixedly mounted on the main body 100 at intervals, forming a stable overall structure.

[0051] like Figure 1 , Figure 2 As shown, two detection elements 200 are fixedly disposed on the main body 100 at intervals. Each detection element 200 has a detection end 201 that can reciprocate in a first direction so that the detection element 200 obtains the displacement of the detection end 201.

[0052] like Figure 1 , Figure 2 As shown, each detection element 200 is equipped with a detection end 201, which can reciprocate in a first direction. This allows the detection end 201 to flexibly move its relative position as needed during the measurement process, enabling the detection element 200 to accurately obtain the displacement of the detection end 201. The displacement is a key parameter for measuring the roll gap size. By moving the detection end 201 and obtaining the displacement, the detection element 200 can accurately reflect the changes in the roll gap size.

[0053] like Figure 1 , Figure 2As shown, two oscillating members 300 are movably connected to the main body 100 at intervals and are arranged correspondingly to the two detection members 200. The middle part of the oscillating member 300 is rotatably connected to the main body 100. The oscillating member 300 has a first end 301 for extending to the circumferential surface of the roller 600 to be tested, and a second end 302 for connecting to the detection end 201. When the two first ends 301 extend to the circumferential surface of the two rollers 600 to be tested, the two oscillating members 300 rotate respectively, and the second end 302 drives the two detection ends 201 to move respectively until the two detection members 200 respectively obtain displacement.

[0054] like Figure 1 , Figure 2 As shown, the oscillating members 300 are movably connected to the main body 100 at intervals and are arranged one-to-one with the two detection members 200. The middle part of the oscillating member 300 is connected to the main body 100 by a rotatable connection, allowing the oscillating member 300 to rotate flexibly during the measurement process. The two ends of the oscillating member 300 are configured as follows: the first end 301 extends to the circumferential surface of the roller 600 to be measured and directly contacts the roller 600; the second end 302 is connected to the detection end 201 to transmit the movement of the oscillating member 300 to the detection end 201.

[0055] like Figure 1 , Figure 2 As shown, during the measurement process, when the first end 301 of the oscillating element 300 extends to the circumferential surface of the two rollers 600 to be measured, the oscillating element 300 will rotate with a corresponding amplitude according to the position of the rollers 600. This rotation is transmitted to the detection end 201 through the second end 302, thereby driving the detection end 201 to move in the first direction. As the detection end 201 moves, the detection element 200 can acquire the displacement in real time. Finally, when the first ends 301 of both oscillating elements 300 accurately extend to the circumferential surface of the two rollers 600 to be measured, and both oscillating elements 300 have completed their rotation, the two detection ends 201 will also acquire the corresponding displacement. Through the measured values ​​of these two displacements, the measurement system can accurately calculate the actual size of the roll gap of the continuous casting machine, thereby providing reliable data support for the control and optimization of the continuous casting process.

[0056] The measurement system in this application is used for measuring the roll gap of a continuous casting machine. The operating principle of the measurement system is as follows: the measurement system includes a main body 100, two detection elements 200 and two swing elements 300, which are fixedly arranged on the main body 100 at intervals. The detection element 200 has a detection end 201 that can reciprocate in a first direction so that the detection element 200 obtains the displacement of the detection end 201.

[0057] The two oscillating members 300 are rotatably connected to the main body 100 and are arranged correspondingly to the two detection members 200. The middle part of the oscillating member 300 is rotatably connected to the main body 100. The oscillating member 300 has a first end 301 for extending to the circumferential surface of the roller 600 to be tested, and a second end 302 for connecting to the detection end 201. When the two first ends 301 extend to the circumferential surface of the two rollers 600 to be tested, the two oscillating members 300 rotate respectively, and the second end 302 drives the two detection ends 201 to move respectively until the two detection members 200 respectively obtain displacement.

[0058] The detection end 201 of the detection element 200 can reciprocate in a first direction to acquire the displacement. Oscillating elements 300 are movably connected to the main body 100 at intervals and are arranged correspondingly to the detection element 200. The first end 301 of the oscillating element 300 extends to the circumferential surface of the roller 600 to be tested, and the second end 302 is connected to the detection end 201. When the first end 301 of the oscillating element 300 contacts the roller 600 to be tested, the oscillating element 300 rotates, causing the detection end 201 to move, thus enabling the detection element 200 to acquire the displacement and thereby achieving the measurement of the roll gap.

[0059] By extending directly from the first end 301 of the swing member 300 to the circumferential surface of the roller 600 to be tested, the actual position of the roller 600 can be accurately sensed, reducing the sources of error in the measurement process. The detection end 201 of the detection member 200 moves under the drive of the swing member 300, directly obtaining the displacement, which can accurately reflect the change of the roll gap and provide reliable data support for the precise control of the continuous casting machine.

[0060] Through reasonable design and connection, the detection component 200 and the swing component 300 ensure stable and reliable relative movement between the components during the measurement process, reduce measurement errors caused by mechanical vibration or loosening, and improve the long-term working stability of the system.

[0061] The rotation of the swing component 300 can automatically drive the detection end 201 to move, without the need for additional power devices or complicated operating procedures. This simplifies the measurement operation, improves measurement efficiency, and enables rapid response to changes in the roll gap during the continuous casting machine production process, providing timely measurement data.

[0062] Since the detection end 201 can reciprocate in the first direction and the swing component 300 can rotate flexibly, the system has the ability to measure continuously and can monitor the changes in the roll gap in real time. This provides continuous and real-time measurement signals for the automated control of the continuous casting machine, which helps to optimize the continuous casting process and improve product quality.

[0063] By adjusting parameters such as the length or angle of the oscillating component 300, this measurement system can adapt to continuous casting machine rolls 600 with different diameters and spacings, exhibiting good versatility and adaptability. It can meet the roll gap measurement needs of various continuous casting machine models and production conditions, reducing equipment procurement and maintenance costs for enterprises. It reduces the frequency and complexity of manual measurement, lowers errors and risks associated with manual operation, saves labor costs, and improves production efficiency, demonstrating good cost-effectiveness in the long run. The oscillating component 300 can measure the reduction of the upper and lower casting rolls separately. Even when the outer arc roll of the casting machine shifts due to bearing damage or cylinder setting deviations, it can still be detected. The obtained measurement results can be analyzed through measurement trends and values ​​to make judgments and provide maintenance suggestions, avoiding measurement errors caused by changes in the position of the roll 600. The overall structure is compact, further reducing the space occupied, especially in complex measurement environments.

[0064] like Figure 1 , Figure 2 As shown, in an optional embodiment, the measuring system includes two elastic elements 303. One end of each elastic element 303 is fixedly connected to the main body 100, and the other end of each elastic element 303 is connected to the second end 302. Rotation of the oscillating element 300 causes deformation of the elastic element 303, and the deformation restoring force of the elastic element 303 drives the oscillating element 300 to rotate and reset. The elastic element 303 is fixedly connected to the main body 100 via a base 401, which can be a metal plate fixed to the main body 100.

[0065] The measurement system also includes two elastic elements 303. One end of each elastic element 303 is fixedly connected to the main body 100, while the other end is connected to the second end 302 of the swing element 300. When the swing element 300 rotates, it causes the elastic elements 303 to deform. This deformation is recoverable; when the external force disappears, the restoring force of the elastic elements 303 can drive the swing element 300 to automatically rotate and reset, thereby realizing the automatic return function of the swing element 300 and ensuring that the measurement system can quickly return to its initial state after each measurement, preparing for the next measurement.

[0066] like Figure 1 , Figure 2As shown, in an optional embodiment, the two detection elements 200 are symmetrically arranged on the main body 100, and the two swing elements 300 are symmetrically arranged on the main body 100. This symmetrical arrangement ensures that the measurement system is subjected to uniform force during measurement, improving the stability and accuracy of the measurement. Simultaneously, the symmetrical arrangement also makes the measurement system easier to install and debug, better adapting to continuous casting machine rolls 600 of different sizes and shapes, further enhancing the versatility and adaptability of the measurement system.

[0067] In an optional embodiment, the detection element 200 and the oscillating element 300 are respectively connected to the main body 100 via a base 401. The base 401 not only provides a stable mounting foundation for the detection element 200 and the oscillating element 300, but also effectively isolates the external environment from the measuring components, reducing interference from vibration, dust, and other factors on measurement accuracy. Furthermore, the connection via the base 401 facilitates individual maintenance and replacement of the detection element 200 and the oscillating element 300, improving the reliability and maintainability of the measurement system.

[0068] like Figure 1 , Figure 2 As shown, in an optional embodiment, the main body 100 is provided with a sealed space 402, and the sealed space 402 is provided with a controller 501 and a power supply unit 502 respectively connected to the detection element 200. The controller 501 is used to read and process the displacement amount, and the power supply unit 502 can supply power to the controller 501 and the detection element 200 respectively.

[0069] The controller 501 reads and processes the displacement data acquired by the detection element 200, converting the raw displacement data into measurement results that can be analyzed and used. The power supply unit 502 provides a stable energy supply to both the controller 501 and the detection element 200, ensuring the measurement system operates normally under various conditions. By placing the controller 501 and the power supply unit 502 within the sealed space 402, these critical components are effectively protected from harsh external environments, extending their service life and improving the overall performance and reliability of the measurement system.

[0070] like Figure 1 , Figure 2As shown, in an optional embodiment, the main body 100 is provided with a partition 403. One side of the partition 403 and the main body 100 enclose the sealed space 402. One side of the detection element 200, which has a detection end 201, penetrates the partition 403 and extends outside the sealed space 402. This ensures that the detection end 201 can contact the external roller 600 to complete the measurement task, while the partition 403 isolates other parts of the detection element 200 from the controller 501 and power supply unit 502 inside the sealed space 402, preventing external environment from contaminating or damaging internal components, thereby achieving efficient operation and long-term stable operation of the measurement system.

[0071] like Figure 1 , Figure 2 As shown, in an optional embodiment, the first end 301 and the second end 302 of the swing member 300 are respectively provided with contact wheels 404.

[0072] like Figure 1 , Figure 2 As shown, in an optional embodiment, the first end 301 and the second end 302 of the oscillating member 300 are respectively rotatably provided with contact wheels 404. This allows the oscillating member 300 to reduce friction through the rolling of the contact wheels 404 when it contacts the roller 600 being measured, thereby achieving smoother rotation. The contact wheels 404 not only protect the surfaces of the oscillating member 300 and the roller 600, preventing wear caused by direct contact, but also improve the service life and measurement accuracy of the measurement system. Simultaneously, the rolling of the contact wheels 404 can better adapt to the minor irregularities on the surface of the roller 600, ensuring that the oscillating member 300 can stably contact the roller 600 and accurately transmit motion.

[0073] The contact wheel 404 is fixed to the swing member 300 via the rotating shaft 405, and the swing member 300 is mounted on the main body 100 via the rotating shaft 405.

[0074] like Figure 1 , Figure 2 As shown, in an optional embodiment, the first end 301 and the second end 302 of the swing member 300 are respectively designed as arcs, and the first end 301 and the second end 302 are respectively provided with wear-resistant coatings.

[0075] The arc shape allows the first end 301 and the second end 302 of the oscillating component 300 to better conform to the circumferential surface of the roller 600, ensuring stable and uniform contact. The addition of a wear-resistant coating further improves the durability of the oscillating component 300. Especially in harsh working environments such as continuous casting machines with high temperatures and high dust, the wear-resistant coating can effectively reduce component damage caused by friction and wear, extend the service life of the oscillating component 300, reduce maintenance costs, and also help maintain the long-term stability and measurement accuracy of the measurement system.

[0076] like Figure 3 As shown, Figure 3 The flowchart of the measurement method provided in the embodiments of this application illustrates that, based on the same inventive concept, this application also provides a method for measuring the roll gap of a continuous casting machine. This measurement method is applied to the aforementioned measurement system and includes:

[0077] Arrange the main body 100 at the two rollers 600 to be tested;

[0078] Move the main body 100 until the first ends 301 of the two swing members 300 respectively contact the circumferential surfaces of the two rollers 600, the swing members 300 rotate synchronously, and the second ends 302 of the swing members 300 drive the detection end 201 of the detection member 200 to move.

[0079] Two displacement data are obtained through the detection element 200, and the roll gap data between the rollers 600 is calculated based on the displacement data.

[0080] Specifically, the main body 100 is first positioned near the two rollers 600 to be tested. As the supporting structure of the measurement system, the accuracy of the main body 100's position directly affects the reliability of the measurement results. During the placement process, it is necessary to ensure that the relative position between the main body 100 and the rollers 600 meets the design requirements of the measurement system so that subsequent measurement operations can proceed smoothly.

[0081] Next, the main body 100 is moved until the first ends 301 of the two oscillating members 300 respectively contact the circumferential surfaces of the two rollers 600. During the contact process, the oscillating members 300 rotate synchronously according to the shape and position of the rollers 600. At the same time, the second ends 302 of the oscillating members 300 drive the detection end 201 of the detection member 200 to move in a first direction. This linkage mechanism ensures that the detection end 201 can make precise displacement adjustments according to the actual position of the rollers 600, thereby obtaining accurate displacement data.

[0082] When the first end 301 of the oscillating member 300 contacts the roller 600 and completes its rotation, the detection member 200 acquires two displacement data points. These two displacement data points correspond to the measurement results of the two rollers 600, respectively. By reading and processing these two displacement data points, the roll gap data between the two rollers 600 can be calculated.

[0083] like Figure 3 , Figure 4 As shown, Figure 4 This is a schematic diagram of the roll gap calculation method provided in an embodiment of this application. In an optional implementation, when the roll gap data between the rollers 600 is calculated,

[0084] Obtain the two displacements S1 and S2;

[0085] Obtain: The distance L from the first end 301 of a swing member 300 to the center of rotation of the swing member 300 1a The distance L from the second end 302 to the center of rotation of the swing member 300 2a The distance r between the center point of the first end 301 and the contact point with the roller 600 1a The distance r between the center point of the second end 302 and the contact point with the detection end 201 2a ;

[0086] Obtain: the distance L from the first end 301 of the other oscillating member 300 to the center of rotation of the oscillating member 300. 1b The distance L from the second end 302 to the center of rotation of the swing member 300 2b The distance r between the center point of the first end 301 and the contact point with the roller 600 1b The distance r between the center point of the second end 302 and the contact point with the detection end 201 2b ;

[0087] Obtain: the distance H between the rotation centers of the two oscillating components 300;
