Description

Technical Field

[0001] This utility model relates to the field of hot rolling technology, and in particular to a slab warpage detection device. Background Technology

[0002] Hot rolling is the opposite of cold rolling. Cold rolling is rolling performed below the crystallization temperature, while hot rolling is rolling performed above the crystallization temperature. A slab is a type of steel billet, formed by continuous casting of molten steel using a continuous casting machine. Generally, a slab with a width-to-thickness ratio greater than 3 is called a slab. It is mainly used for rolling plates, but rolling has not yet begun.

[0003] In hot rolling production, continuously cast slabs sometimes have defects in their shape, especially in the form of buckled or warped ends. Slabs with buckled or warped ends often collide with the roller conveyor, and poor contact with the roller conveyor can easily cause the motor of the steel loading roller conveyor to trip, resulting in the roller conveyor stopping. Heating operations require frequent contact with electrical personnel to restart the motor, reducing the motor's lifespan and affecting the steel loading rate. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems and shortcomings by proposing a slab warpage detection device: if a bridge appears on the outer wall of the slab, the top of the sliding rod contacts the outer wall of the pressure sensor, and the controller stops driving the motor after receiving the signal, indicating that the slab is irregular beyond the standard, affecting the processing of the slab and requiring processing. This facilitates the detection of the slab's flatness, avoids the slab from hitting the roller conveyor, maintains production stability, and avoids frequent equipment starts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A slab warpage detection device includes two support rods. Both ends of the two support rods, close to each other on one side of their outer walls, are rotatably connected to drive rollers. A mounting frame is installed at the center of the top outer wall of each support rod. A detection structure is provided on one side of the outer wall of the mounting frame, and a controller is installed on the other side of the outer wall of the mounting frame. The detection structure includes a detection groove formed on one side of the outer wall of the mounting frame, mounting holes equally spaced on the outer wall of the detection groove, a sliding tube installed on the inner wall of the mounting hole, a sliding rod slidably connected to the bottom outer wall of the sliding tube, and a limiting ring welded to the outer wall of the sliding rod.

[0007] Preferably, a contact block is welded to the bottom outer wall of the sliding rod, and the bottom outer walls of the contact block are provided with inclined surfaces on both sides.

[0008] Preferably, a sliding ring is installed on the inner wall of the top end of the sliding tube, and the outer wall of the sliding rod is slidably connected to the inner wall at the center of the sliding ring, and the outer wall of the limiting ring is slidably connected to the inner wall of the sliding tube.

[0009] Preferably, the mounting bracket has equidistantly distributed adjustment holes on the inner wall of the detection groove at the mounting hole, and each adjustment hole is equipped with a mounting plate. A pressure sensor is installed at the center of the bottom outer wall of the mounting plate, and the top outer wall of the sliding rod is in contact with the outer wall of the pressure sensor.

[0010] Preferably, a support spring is installed on the top outer wall of the limiting ring, and the other end of the support spring contacts the bottom outer wall of the sliding ring.

[0011] Preferably, support rollers are rotatably connected at equal intervals at the top of the outer wall between the support rods, and a support belt is connected to the outer wall of the support rollers and the drive roller. The outer walls on both sides of the mounting frame are provided with mounting grooves, and threaded holes are provided at the mounting grooves and the outer walls of the support rods. A drive motor is installed at both ends of one side of the outer wall of a support rod, and the output shaft of the drive motor is connected to one end of the drive roller.

[0012] Preferably, the drive motor and the pressure sensor are connected to the controller via wires, and the controller is connected to the power supply via wires.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The mounting plate and pressure sensor are installed in the mounting slot of the mounting bracket through the adjustment hole, which facilitates the adjustment of the distance between them and the sliding rod, the adjustment of the qualified range of the slab, and the inspection of the slab;

[0015] 2. If bridge edges appear on the outer wall of the slab, and the top of the sliding rod contacts the outer wall of the pressure sensor, the controller will stop driving the motor after receiving the signal. This indicates that the slab is irregular and exceeds the standard, affecting the processing of the slab and requiring processing. This facilitates the detection of the slab's flatness, prevents the slab from hitting the roller conveyor, maintains production stability, and avoids frequent equipment starts.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1:

[0023] Reference Figure 1-4 As shown, a slab warpage detection device includes two support rods 1. Both ends of the two support rods 1 are rotatably connected to drive rollers 2 on one side of their outer walls. A mounting frame 6 is installed at the center of the top outer wall of the support rods 1. A detection structure 8 is provided on one side of the outer wall of the mounting frame 6. A controller 20 is installed on one side of the outer wall of the mounting frame 6.

[0024] Support rollers 3 are rotatably connected at the top of the outer wall between the support rods 1, and a support belt 4 is connected to the outer wall of the support rollers 3 and the drive rollers 2. The outer walls of the mounting frame 6 are provided with mounting grooves 7, and threaded holes are provided at the mounting grooves 7 and the outer wall of the support rods 1. A drive motor 5 is installed at both ends of the outer wall of one side of a support rod 1, and the output shaft of the drive motor 5 is connected to one end of the drive roller 2. The drive roller 2 and the support roller 3 drive the slab to move through the drive motor 5 and the support belt 4. The support rollers 3 support the slab to ensure the stability of its movement.

[0025] The drive motor 5 and the pressure sensor 19 are connected to the controller 20 via wires, and the controller 20 is connected to the power supply via wires. The slab is placed on the support belt 4 and the drive motor 5 is started to drive the drive roller 2 to rotate. After the drive roller 2 rotates, it pulls the support belt 4 to move on the support roller 3 and the drive roller 2, thus driving the slab to move in parallel.

[0026] Example 2:

[0027] Reference Figure 1 and Figure 3-4As shown, the detection structure 8 includes a detection groove 9 opened on one side of the outer wall of the mounting frame 6, mounting holes 10 opened at equal intervals on the outer wall of the detection groove 9, a sliding tube 11 installed on the inner wall of the mounting hole 10, a sliding rod 12 slidably connected to the bottom outer wall of the sliding tube 11, and a limiting ring 13 welded to the outer wall of the sliding rod 12. The sliding rod 12 on the contact block 16 moves upward to compress the support spring 14, so that the top of the sliding rod 12 contacts the outer wall of the pressure sensor 19. After the controller 20 receives the signal, it stops the drive motor 5 and reverses to return the slab. If the slab is irregular and exceeds the standard, it will affect the processing of the slab and needs to be processed. This facilitates the detection of the flatness of the slab, avoids the slab from hitting the roller table, maintains production stability, and avoids frequent equipment starts.

[0028] A contact block 16 is welded to the bottom outer wall of the sliding rod 12, and the bottom outer walls of the contact block 16 on both sides are provided with inclined surfaces;

[0029] A sliding ring 15 is installed on the inner wall of the top end of the sliding tube 11, and the outer wall of the sliding rod 12 is slidably connected to the inner wall of the center of the sliding ring 15. The outer wall of the limiting ring 13 is slidably connected to the inner wall of the sliding tube 11. The contact block 16 contacts the outer wall of the slab and drives the sliding rod 12 and the limiting ring 13 to slide in the sliding tube 11 according to the curvature of the slab surface, so as to display the curvature of the slab surface in real time on one end of the sliding rod 12, which is convenient for detecting the surface of the slab.

[0030] The mounting frame 6 has equidistant adjustment holes 17 on the inner wall of the detection groove 9 at the mounting hole 10, and each adjustment hole 17 is equipped with a mounting plate 18. A pressure sensor 19 is installed at the center of the bottom outer wall of the mounting plate 18, and the top outer wall of the sliding rod 12 contacts the outer wall of the pressure sensor 19. The mounting plate 18 and the pressure sensor 19 are installed in the mounting groove 7 of the mounting frame 6 through the adjustment holes 17, which facilitates the adjustment of the distance between them and the sliding rod 12, facilitates the adjustment of the qualified range of the slab, and facilitates the detection of the slab.

[0031] A support spring 14 is installed on the top outer wall of the limiting ring 13, and the other end of the support spring 14 contacts the bottom outer wall of the sliding ring 15. The sliding rod 12 slides on the inner wall of the sliding tube 11 through the limiting ring 13. The support spring 14, together with the sliding ring 13, ensures that the bottom end of the sliding rod 12 is always in contact with the outer wall of the slab, thus ensuring the accuracy of the detection and facilitating the early screening of the slab.

[0032] Working principle: When in use, the device is installed before the slab is processed. The slab is placed on the support belt 4 and the drive motor 5 is started to drive the drive roller 2 to rotate. After the drive roller 2 rotates, it pulls the support belt 4 to move on the support roller 3 and the drive roller 2, causing the slab to move parallel. The slab moves to the mounting frame 6, and the surface of the slab contacts the inclined surface of the contact block 16. The contact block 16 slides on the outer wall of the slab, causing the sliding rod 12 to slide in the sliding tube 11. At this time, the top of the sliding rod 12 does not contact the outer wall of the pressure sensor 19. As the support belt 4 moves, if the outer wall of the slab is bridged or severely bridging, the sliding rod 12 on the contact block 16 moves upward to compress the support spring 14, so that the top of the sliding rod 12 contacts the outer wall of the pressure sensor 19. After receiving the signal, the controller 20 stops the drive motor 5 and reverses to return the slab. If the slab is irregular and exceeds the standard, it will affect the processing of the slab and needs to be processed. This facilitates the detection of the flatness of the slab, avoids the slab from hitting the roller table, maintains production stability, and avoids frequent equipment starts.
