Description

Technical Field

[0001] The present application belongs to the technical field of roll gap measurement, and specifically relates to a roll gap measuring instrument and an integrated continuous casting machine online roll gap measuring device. Background Art

[0002] Slab continuous casting machines are specialized equipment that pressure-casts molten steel into billets. The dimensional accuracy of the billets depends on the roll gap control. Poor roll gap control can lead to defects such as center porosity and cracks in the billets, and in severe cases, steel breakouts. This is crucial for production personnel. Furthermore, the rotation of the casting rolls is a key concern for production personnel. If poor roll rotation, or even dead rolls, are not detected or replaced promptly, large quantities of billets will be damaged, resulting in significant economic losses.

[0003] Existing technology generally uses roll gap meters to ensure roll gap accuracy in casting machines. Typical examples include dummy head replacement roll gap meters. These meters measure a wide range of parameters, including roll gap, roll deflection, roll rotation, arc alignment, and water volume. While comprehensive, they require replacement of the dummy head and require separate production organization, each installation taking approximately four hours and impacting billet production. In recent years, online roll gap meters installed on the dummy bar have gained popularity. These meters can measure the roll gap at every casting start, providing a high frequency and no impact on billet production. This makes them popular with manufacturers.

[0004] In continuous casting machines, measuring the roll gap is crucial for ensuring the quality and dimensional accuracy of the cast billets. Traditional roll gap measurement methods suffer from low measurement accuracy and complex operation, making them difficult to meet the precise roll gap control requirements of modern continuous casting machines.

DETAILED DESCRIPTION

[0046] In order to enable those skilled in the art to understand the present application more clearly, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of this application.

[0047] In addition, this application may repeat reference numbers and / or reference letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials, but those of ordinary skill in the art will recognize the application of other processes and / or the use of other materials.

[0048] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0049] The embodiment of the present invention discloses a roll gap measuring instrument 1000, which aims to improve the accuracy of roll gap measurement and the convenience of operation, thereby monitoring the states of roll gap, arc alignment and roll rotation in real time during the continuous casting process.

[0050] The technical solution of this application is described in detail below through specific embodiments:

[0051] See Figure 1 、 Figure 2 and Figure 3In a first embodiment of the present application, a roll gap measuring instrument 1000 is provided, which includes a mounting frame 100 and a measuring assembly 200. The measuring assembly 200 includes a swing arm 210, a first elastic member (not shown in the figure), a shift block 230, a detection member 240, and a first detector 220. The swing arm 210 is rotatably connected to the mounting frame 100, the shift block 230 is connected to the swing arm 210, and the shift block 230 is provided with a toothed portion. The first detector 220 is mounted on the mounting frame 100, and the detection member 240 is slidably engaged with the first detector 220. The detection member 240 is provided with a rack that meshes with the toothed portion. Two first elastic members may be provided, one located on either side of the detection member 240. The two ends of one first elastic member act on the first detector 220 and the detection member 240, respectively. The other ends of the other first elastic member act on the end of the detection member 240 facing away from the first detector 220 and the mounting bracket 230, respectively. The two first elastic members act together to drive the detection member 240 and the swing arm 210 back to their initial positions. When the swing arm 210 contacts the roller 3000 to be measured, the roller 3000 to be measured pushes the swing arm 210 to swing and deviate from its initial position. When the swing arm 210 drives the shift block 230 to rotate, the shift block 230 drives the detection member 240 to move. The first detector 220 is used to measure the distance traveled by the detection member 240. The swing amplitude of the swing arm 210 is calculated based on the distance traveled by the detection member 240, thereby determining the roller gap between the rollers 3000 to be measured.

[0052] Among them, the swing arm 210 is a structure that rotates around a fixed axis, and the distances between its two end portions and the rotation axis are fixed values. Therefore, based on the horizontal movement distance of one end, the horizontal movement distance and vertical movement distance of the other end can be calculated, thereby calculating the roller gap between the rollers 3000 to be measured.

[0053] The roller gap measuring instrument 1000 disclosed in this embodiment achieves high-precision measurement of the roller gap through the cooperation of the swing arm 210, the shift block 230, the detection member 240 and the first detector 220, thereby improving the accuracy and reliability of the measurement results. Through the sliding cooperation between the detection member 240 and the first detector 220, and the precise engagement of the rack on the detection member 240 with the teeth on the shift block 230, the tiny swing amplitude of the swing arm 210 can be captured very accurately. Compared with direct electronic measurement, this mechanical transmission method can sometimes provide higher stability and accuracy, especially in harsh industrial environments such as high temperature and dust. The design of the first elastic member (such as a spring) ensures that the swing arm 210 and the detection member 240 can automatically return to the initial position after measurement, without the need for manual reset, thereby improving measurement efficiency. This automatic reset mechanism also ensures the stability and consistency of continuous measurement. The direct contact measurement method between the swing arm 210 and the roller 3000 to be measured enables the measuring instrument to adapt to rollers of different sizes and materials, and has a wide range of applicability. At the same time, since the measurement principle is based on mechanical transmission, it is relatively insensitive to changes in the surface conditions of the roller (such as roughness, coating, etc.), which improves the versatility of the measurement.

[0054] See Figure 4 、 Figure 5 、 Figure 6 as well as Figure 7 In one embodiment, the measuring assembly 200 further includes a connecting shaft 280 , which is rotatably connected to the mounting bracket 100 , one end of the connecting shaft 280 is connected to the swing arm 210 , and the other end of the connecting shaft 280 is connected to the shift block 230 .

[0055] The connecting shaft 280 acts as a bridge between the swing arm 210 and the shift block 230, strengthening the connection between them. This makes the entire measuring assembly 200 more stable under load and less susceptible to deformation or damage. The design of the connecting shaft 280 allows the swinging motion of the swing arm 210 to be transmitted to the shift block 230 more directly and efficiently, reducing energy loss during the transfer process. When the swing arm 210 is pushed by the roller 3000 to be measured and swung, the shift block 230 responds more quickly and drives the probe 240, thereby improving the speed and accuracy of the measurement.

[0056] In one embodiment, the measuring components 200 are provided in two groups, and the two groups of measuring components 200 are symmetrically arranged along the mounting frame 100 so that the two swing arms 210 respectively extend to the outside of two opposite side walls of the mounting frame 100 .

[0057] On the one hand, the two sets of measuring assemblies 200 can simultaneously measure the upper and lower sides of the roller 3000 to be measured. On the other hand, under certain complex working conditions, the roll gap may change unevenly due to various reasons (such as temperature fluctuations and material expansion). The two symmetrically arranged measuring assemblies 200 can monitor these changes in real time and take appropriate adjustments to ensure production process stability and product quality.

[0058] In one embodiment, the connecting shafts 280 of the two sets of measuring components 200 are coaxially arranged, and one connecting shaft 280 is sleeved outside the other connecting shaft 280, and the two connecting shafts 280 rotate independently.

[0059] The coaxial arrangement of the connecting shaft 280 makes the entire measurement assembly 200 more compact, effectively saving installation space. This is particularly important for industrial sites with limited space, as it can improve the layout flexibility and space utilization of the equipment.

[0060] The sleeved connecting shaft 280 design increases the rigidity of the entire measuring assembly 200, making it more stable when subjected to force. This structure helps reduce measurement errors caused by vibration or impact, and improves measurement accuracy and stability.

[0061] Although the two connecting shafts 280 rotate independently, their coaxial arrangement enables the two sets of measurement components 200 to maintain relative synchronization during the measurement process, which helps to eliminate errors caused by measurement time differences and improve the real-time and accuracy of the measurement.

[0062] In one embodiment, a groove 241 is provided on the side of the probe 240 facing away from the rack. The groove 241 is arranged parallel to the rack, and the depth of the groove 241 gradually decreases from the middle toward the two ends. The measuring assembly 200 also includes a second elastic member 260 and a limit bar 270. The limit bar 270 is arranged perpendicular to the probe 240, and the first end of the limit bar 270 is inserted into the groove 241. The limit bar 270 is slidably connected to the mounting bracket 100. The two ends of the second elastic member 260 act on the second end of the limit bar 270 and the mounting bracket 100 respectively. The second elastic member 260 is used to drive the limit bar 270 to move toward the probe 240 to push the probe 240 back to its initial position.

[0063] By driving the limiting bar 270 toward the detection member 240 through the second elastic member 260, the detection member 240 can be more effectively pushed back to its initial position. This design not only provides additional restoring force, but also helps maintain the stability of the detection member 240 during the reset process, reducing errors caused by shaking or vibration.

[0064] The recessed depth of the groove 241 gradually decreases from its center toward its ends, allowing the limit bar 270 to gradually adapt to the movement trajectory of the probe 240 when inserted into the groove 241, thereby more smoothly pushing the probe 240 back to its original position. This gradual return mechanism helps reduce impact and friction during the return process, thereby extending the service life of the measuring assembly 200.

[0065] Since the limit bar 270 is arranged perpendicular to the detection member 240 and is slidably connected to the mounting frame 100, when the detection member 240 is pushed by the shift block 230 and moves, the limit bar 270 can provide a stable support point to prevent the detection member 240 from deflecting or tilting during the movement.

[0066] By adjusting the insertion depth of the limit bar 270 in the groove 241, the reset position and movement range of the probe 240 can be flexibly adjusted. This design enables the measuring assembly 200 to adapt to the measurement requirements of rollers of different sizes and shapes, improving the versatility and flexibility of the equipment.

[0067] The cooperation between the first elastic member and the second elastic member 260 can realize the reset of the detection member 240 , so that the movement of the detection member 240 can be more stable and the detection member 240 can be reset more quickly.

[0068] In one embodiment, the measuring assembly 200 further includes a push rod 250, which is disposed on the side of the detection member 240 facing away from the first detector 220. When aligning the roll gap measuring instrument 1000, the roll gap measuring instrument 1000 moves along the rotation axis of the swing arm 210. During this process, the swing arm may collide with the dummy bar trolley or rub against the roll, potentially damaging the swing arm 210 or causing inaccurate measurement data. Before the roll gap measuring instrument 1000 is centered, the push rod pushes the measuring member 240 to drive the swing arm 210 back into the mounting frame 100, thereby protecting the measuring assembly 200 from damage during the alignment process.

[0069] The roll gap measuring instrument 1000 disclosed in this application operates as follows: When the roller 3000 to be measured contacts the swing arm 210, the thrust of the roller causes the swing arm 210 to swing about a pivot point on the mounting frame 100, thereby deviating from its initial position. The swinging motion of the swing arm 210 is transmitted to the shift block 230. The teeth on the shift block 230 engage with the rack on the probe 240, thereby driving the probe 240 along the sliding track of the first detector 220. The first detector 220 measures the distance traveled by the measuring member 240. This distance is used to determine the swing amplitude of the swing arm 210, thereby calculating the roll gap between the rollers to be measured. The precise engagement of the rack on the probe 240 with the teeth on the shift block 230 ensures accurate and stable displacement measurement. A first elastic member (e.g., a spring) and a second elastic member 260 act together on the probe 240 and the swing arm 210, ensuring that after a measurement is completed, they quickly and smoothly return to their initial positions, ready for the next measurement. The second elastic member 260 cooperates with the groove 241 on the detection member 240 through the limiting strip 270, providing a progressive reset mechanism, thereby reducing the impact and friction during the reset process.

[0070] See Figure 8 、 Figure 9 and Figure 10 Based on the same inventive concept, the second embodiment of the present application discloses an integrated continuous casting machine online roll gap measuring device, including a box body 2000 and at least two roll gap measuring instruments 1000 of the above-mentioned first aspect, and each roll gap measuring instrument 1000 is arranged at intervals along the length direction of the box body 2000.

[0071] The integrated online roll gap measuring device for continuous casting machine disclosed in this embodiment can accurately measure the roll gap in real time, which helps to optimize the production parameters and processes of the continuous casting machine, thereby improving production efficiency, reducing production costs, and ensuring the quality of the ingots. The integrated online roll gap measuring device for continuous casting machine disclosed in this embodiment can be widely used in industrial fields such as steel mills and metallurgy, and can achieve accurate measurement and real-time monitoring of the roll gap. During the continuous casting production process, the device can detect potential faults in a timely manner, improve the reliability and stability of the equipment, and thus ensure the quality and output of the ingots.

[0072] See Figure 10 and Figure 11In one embodiment, the integrated continuous casting machine online roll gap measurement device further includes an arc measurement assembly 5000, which includes an arc plate 5100, a measuring device 5300, and two third elastic members 5200. The arc plate 5100 is rotatably connected to the housing 2000. The two ends of the third elastic member 5200 act on the mounting frame 100 and the arc plate 5100, respectively. The third elastic member 5200 is used to drive the end of the arc plate 5100 to rotate toward the roll 3000 to be measured, and the two third elastic members 5200 act on the two ends of the arc plate 5100, respectively. The measuring device 5300 is mounted on the housing 2000 and is used to measure the rotation angle of the arc plate 5100.

[0073] The arc measurement assembly 5000 measures the rotation angle of the arc plate 5100, indirectly reflecting changes in the position of the roller 3000 to be measured. The measuring device 5300 measures the rotation angle of the arc plate 5100 in real time and transmits the data to the control system. This helps to promptly detect changes in the position of the roller 3000 to be measured, allowing appropriate adjustments to be taken to ensure stable operation of the continuous casting machine. The design of the arc measurement assembly 5000 enables it to adapt to the measurement needs of rollers of different sizes and shapes. By adjusting the preload of the third elastic member 5200 or changing the size of the arc plate 5100, accurate measurement of rollers of different curvatures can be achieved.

[0074] In one embodiment, the arc alignment plate 5100 is provided with a slide groove 5101 extending along the height direction of the arc alignment plate 5100. The arc alignment measurement assembly 5000 also includes a limit rod 5400 and two rotating blocks 5500. The limit rod 5400 is mounted on the housing 2000 and inserted into the slide groove 5101. The limit rod 5400 and the slide groove 5101 are slidably engaged, and the two rotating blocks 5500 are both rotatably connected to the housing 2000. The end of the third elastic member 5200 facing away from the arc alignment plate 5100 is connected to the rotating block 5500. The two rotating blocks 5500 are provided in a one-to-one correspondence with the two third elastic members 5200.

[0075] The chute 5101 and the limiting rod 5400 cooperate to allow the limiting rod 5400 to slide up and down within the chute 5101, thereby providing a certain degree of guidance and limiting effect on the rotation of the arc plate 5100. This increases the stability of the arc plate 5100 during rotation and reduces measurement errors caused by shaking or deflection. When the integrated continuous casting machine online roll gap measurement device passes the active drive roller, the arc plate 5100 can return directly to the housing 200, thereby protecting the arc measurement assembly 5000.

[0076] In one embodiment, the cross section of the limiting rod 5400 is circular, which can ensure that the arc plate 5100 can rotate relative to the limiting rod 5400 and move up and down relative to the limiting rod 5400.

[0077] In one embodiment, the arc measurement components 5000 are provided in two groups. The two groups of arc measurement components 5000 are respectively provided at both ends of the box 2000 , and each roll gap measuring instrument 1000 is located between the two groups of arc measurement components 5000 .

[0078] Two sets of arc measurement assemblies 5000 are located at either end of the housing 2000, forming a symmetrical layout that makes the entire measurement device more balanced and stable. The roll gap measuring instrument 1000 is located between the two sets of arc measurement assemblies 5000. This layout facilitates simultaneous measurement of the roll gap and arc, improving the comprehensiveness and accuracy of the measurements.

[0079] See Figure 10 、 Figure 12 and Figure 13 In one embodiment, the integrated continuous casting machine online roll gap measurement device further includes a roll rotation measurement assembly 4000, which includes a turret 4100, a contact wheel 4200, a fourth elastic member 4400, and a second detector 4300. The first end of the turret 4100 is rotatably engaged with the housing 2000. The contact wheel 4200 is rotatably connected to the second end of the turret 4100. The ends of the fourth elastic member 4400 act on the housing 2000 and the turret 4100, respectively, and the fourth elastic member 4400 is used to drive the second end of the turret 4100 to rotate toward the outside of the housing 2000. The second detector 4300 is mounted on the turret 4100, and the output end of the second detector 4300 is connected to the rotation shaft of the contact wheel 4200. The second detector 4300 is used to measure the torque of the contact wheel 4200.

[0080] When the contact wheel 4200 contacts the roller 3000 to be measured, the second detector 4300 can measure the torque of the contact wheel 4200. If the torque value measured by the second detector 4300 is small, it indicates that the roller 3000 to be measured is rotating normally. If the torque value measured by the second detector 4300 is large, it indicates that the rotation of the roller 3000 to be measured is affected to a certain extent. Because the roller 3000 to be measured cannot rotate normally, when the contact wheel 4200 passes by the roller 3000 to be measured, there is a large friction between the contact wheel 4200 and the roller 3000 to be measured, resulting in a large torque generated by the contact wheel 4200.

[0081] The roller rotation measurement assembly 4000 can monitor the rotation of the roller 3000 to be measured in real time, and promptly detect faults such as roller stall or abnormal speed, providing important data support for quality control and equipment maintenance during the production process.

[0082] The integrated online roll gap measurement device for a continuous casting machine disclosed in this application operates as follows: a third elastic member 5200 pushes the end of the arc plate 5100 to rotate toward the roll 3000 to be measured until it contacts the roll 3000. A measuring device 5300 records the rotation angle of the arc plate 5100, which reflects the position of the roll 3000 to be measured. A limiting rod 5400 slides within a chute 5101, ensuring the stability of the arc plate 5100 during rotation. The cooperation between the rotating block 5500 and the third elastic member 5200 allows for fine-tuning of the arc plate 5100 to accommodate the size and position of different rolls 3000 to be measured.

[0083] The fourth elastic member 4400 pushes the second end of the rotating frame 4100 to rotate toward the outside of the housing 2000, causing the contact wheel 4200 to contact the roller 3000 to be measured. The output end of the second detector 4300 is connected to the rotation axis of the contact wheel 4200. The second detector 4300 is used to measure the friction between the contact wheel 4200 and the roller 3000 to be measured. Based on the friction between the contact wheel 4200 and the roller 3000 to be measured, whether the roller 3000 to be measured is rotating normally can be determined.

[0084] Collect data from the measurement assembly 200, the roll rotation measurement assembly 4000, and the roll rotation measurement assembly 5000 for comprehensive analysis. Based on the analysis results, adjust the operating parameters of the continuous casting machine or perform necessary maintenance. Store the measurement results and feedback information in a database for subsequent analysis and improvement.

[0085] The integrated online roll gap measurement device for continuous casting machines disclosed in this application integrates roll gap measurement, arc alignment measurement, and roll rotation measurement functions, enabling comprehensive monitoring of multiple key parameters in the continuous casting machine. The entire measurement device has a simple structure, convenient operation, and is easy to install and maintain on the continuous casting machine.
