Description

Technical Field

[0001] This utility model belongs to the technical field of temperature measurement equipment for billet production, specifically relating to a surface temperature measurement device for a double-station round billet straightening section. Background Technology

[0002] Currently, seamless steel pipes are generally manufactured using a process of heating round billets, hot rolling piercing, and continuous rolling. During the production of round billets, the surface temperature of the billet is a crucial process parameter for adjusting the secondary cooling water flow rate, controlling the billet drawing speed, and determining the depth of the liquid cavity. To understand the production status of the round billet, it is necessary to measure the surface temperature of the curved section and the straightening section. Most companies use non-contact infrared thermometers to intermittently measure the temperature at several fixed locations in the curved and straightening sections. While this method facilitates the installation and maintenance of the equipment, it results in incomplete data on the surface temperature distribution in the curved and straightening sections, with some data requiring estimation. Therefore, it is necessary to develop a device capable of continuously measuring the surface temperature of the curved or straightening sections of the round billet.

[0003] After searching, three patent documents were found to be most relevant to this utility model technology. The specific contents are described below:

[0004] Patent document CN 202011165770.3 discloses a method and device for measuring the surface temperature distribution of a continuously cast billet. The method includes acquiring an infrared image of the billet, correcting the infrared image, identifying the billet target in the corrected infrared image, acquiring the infrared temperature values ​​corresponding to multiple temperature measurement points on the surface of the billet target, and then obtaining the temperature distribution of the billet surface. This invention is ingenious and can realize non-contact measurement of the temperature distribution of the billet surface. It can provide accurate and reliable data support and guidance for various application scenarios such as online control of continuous casting production and billet quality analysis. However, this invention only provides a method for measuring the surface temperature distribution of continuously cast billets and does not provide a specific measuring device.

[0005] Patent document CN 202321463053.8 discloses an online real-time detection device for the surface temperature distribution of continuously cast billets. The device includes a shell, an infrared thermometer, a drive wheel, a motor, a hose, a slider, a support column, and a ring track. The device is ingeniously designed. The infrared thermometer uses a rotary scan to monitor the overall surface temperature distribution of the continuously cast billet. The signal is transmitted through a cable. The scanning speed of the infrared thermometer is set according to the moving speed of the continuously cast billet. It can monitor the surface temperature of the outer circumference of the continuously cast billet. Since the drive wheel can only rotate back and forth along the ring track, the device can only measure the surface temperature of the outer circumference of the continuously cast billet at a fixed position. It is not suitable for measuring the surface temperature of the billet in the longitudinal direction.

[0006] Patent document CN 202422908977.5 discloses a contact-type device for measuring the surface temperature of continuously cast billets. The device includes a base plate, a stabilizing frame, a support frame, a screw, a motor, an adjustment structure, a contact component, a mounting frame, a guide ring, a stabilizing rod, a rolling wheel, a telescopic tube, a contact rod, a spring, and a temperature sensor. The device is ingeniously designed. The motor drives the screw to rotate, which allows the mounting frame to move up and down within the support frame and the telescopic tube to move left and right on the outer wall of the mounting frame to adjust the temperature detection position. Utilizing the self-balancing characteristic of the spring, it can ensure that the temperature sensor is always in effective contact with the surface of the billet. This device is only suitable for contact-type measurement of the surface temperature of continuously cast billets. Utility Model Content

[0049] The present invention provides an assembly method for a surface temperature measuring device for a dual-station round casting billet straightening section.

[0050] Combination Figures 1 to 18As shown, firstly, the six linear bearings 4 are arranged in pairs facing each other, and the twenty-four sixth bosses 402 are respectively inserted into the six fourth through holes 605 of the three third brackets 6. At this time, the twenty-four second through holes 403 of the six linear bearings 4 and the twenty-four fourth screw holes 606 of the three third brackets 6 are aligned. Then, the twenty-four bolts 10 are passed through the twenty-four second through holes 403 and screwed into the twenty-four fourth screw holes 606. In this way, the six linear bearings 4 and the three third brackets 6 can be assembled.

[0051] Then, the twelve middle parts of the twelve guide shafts 9 are respectively inserted into the twenty-four third through holes 404 of the six linear bearings 4. Then, the two first brackets 1 are arranged opposite each other. Then, the twenty-four ends of the twelve guide shafts 9 are respectively inserted into the twenty-four first grooves 106 of the two first brackets 1. In this way, the six linear bearings 4, the twelve guide shafts 9 and the two first brackets 1 can be assembled.

[0052] Then, a base plate 2 is horizontally set, and the four first bodies 101 of the two first brackets 1 are simultaneously set on the upper surface of the base plate 2. The sixteen first screw holes 105 of the two first brackets 1 and the sixteen first through holes 201 of the base plate 2 are aligned. Then, sixteen bolts 10 are passed through the sixteen first through holes 201 and screwed into the sixteen first screw holes 105. In this way, the two first brackets 1 and the base plate 2 can be assembled.

[0053] Then, twelve rolling bearings 11 are installed in the twelve second grooves 703 of the six fourth brackets 7. The six fourth brackets 7 are then arranged in pairs facing each other. The twelve bearing segments 504 of the six second brackets 5 are then respectively inserted into the twelve rolling bearings 11. In this way, the six fourth brackets 7, the twelve rolling bearings 11 and the six second brackets 5 can be assembled.

[0054] Then, the six eleventh protrusions 702 of the six fourth brackets 7 are respectively fitted onto the front and rear twelve end faces of the twelve ninth protrusions 602 of the three third brackets 6, and the twenty-four sixth through holes 705 of the six fourth brackets 7 and the twenty-four third screw holes 604 of the three third brackets 6 are aligned.

[0056] The principle for setting the swing direction of the second support in the surface temperature measuring device of the dual-station round casting billet straightening section provided by this utility model

[0057] Combination Figure 1 and Figure 2 As shown in the schematic diagram of the main structure of this utility model, for ease of description, we can consider the two second supports 5 arranged opposite each other as a group, and the six second supports 5 can be divided into three groups. We can define the second support 5 on the left in each group as ① and the second support 5 on the right as ②. The four bearing segments 504 of the two second supports 5 can all be used as swing axes, and we can set them all as O.

[0058] like Figure 1 As shown, assuming that initially both ① and ② in each group are in a casual arrangement, that is, the eighth protrusion 503 is in an upright arrangement, after simplification as follows: Figure 19 As shown, along the two swing axes O, ① swings 90 degrees counterclockwise, and ② swings 90 degrees clockwise. Then, both ① and ② are in working position, that is, the eighth boss 503 is in a horizontal position. We can define the swing direction of ① and ② as positive.

[0059] like Figure 2 As shown, assuming that initially both ① and ② in each group are in a working configuration, that is, the eighth protrusion 503 is horizontally positioned, the simplified configuration is as follows: Figure 20 As shown, along the two swing axes O, ① swings 90 degrees clockwise, while ② swings 90 degrees counterclockwise. Thus, both ① and ② are in a relaxed configuration, meaning that the eighth protrusion 503 is in a vertical configuration. We can define the swing directions of ① and ② as opposite.

[0060] The working principle of the surface temperature measuring device for the double-station round casting billet straightening section provided by this utility model

[0061] Combination Figure 1 and Figure 2 As shown, for ease of description, let's consider the two temperature measuring guns 3 arranged opposite each other as a group. Then, the six temperature measuring guns 3 can be divided into three groups. Let's define the temperature measuring gun 3 on the left in each group as ③, and the temperature measuring gun 3 on the right as ④. Let's assume that the round casting 12 uses a three-strand casting production method, and that the straightening section of the round casting 12 is a horizontal and straight cylindrical structure. Let's divide the straightening section AC continuously into sections AB and BC, simplifying it as follows: Figure 21 and Figure 22 As shown;

[0062] For the operating routes of the three sets of temperature measuring guns 3, forward temperature measurement mode and reverse temperature measurement mode were respectively set; since the operating route of the round casting billet 12 is point A→point B→point C, if point A is taken as the starting point and point C as the ending point, and the surface temperature of the straightening section AC is continuously measured, this temperature measurement route can be defined as the forward temperature measurement mode, such as... Figure 21 As shown; if point C is taken as the starting point and point A as the ending point, and the surface temperature of the straightening section CA is continuously measured, this temperature measurement route can be defined as a reverse temperature measurement mode, such as... Figure 22 As shown;

[0063] Combination Figure 21 As shown, to simplify the operation, let's take the forward temperature measurement mode as an example. The starting point of temperature measurement in ③ is point A and the ending point is point B. The starting point of temperature measurement in ④ is point B and the ending point is point C. Since the lengths of segments AB and BC are both equal to the distance between the center lines of ③ and ④, that is, segment AB = segment BC, and combining segment AB + segment BC = segment AC, we can deduce that segment AB = segment AC / 2. It should be ensured that the distance between the center lines of ③ and ④ is exactly equal to half the length of the straightening segment AC of the round billet 12.

[0064] In order to enable all six second supports 5 to swing precisely at a 90-degree angle, a coupling and a servo motor can be installed at the outer end of each of the six bearing sections 504 on one side of the six second supports 5. Since the encoder can detect the position, speed and acceleration of the rotor in a timely manner and feed this information back to the servo driver in a timely manner, the servo motor can be precisely controlled. Therefore, by driving six servo motors respectively and precisely controlling the rotation speed and rotation angle of the six servo motors, the six second supports 5 can be precisely swung by means of the six couplings.

[0065] To enable precise left-right movement of all six linear bearings 4, it is advisable to group two linear bearings 4 that are arranged opposite each other, thus dividing the six linear bearings 4 into three groups. Considering all factors, there are two relatively economical transmission methods that can achieve precise left-right movement of the six linear bearings 4: one is a transmission method that uses a servo motor, coupling, pulley, and drive belt in combination; the other is a transmission method that uses a servo motor, coupling, gear, and rack in combination.

[0066] A transmission method combining servo motors, couplings, pulleys, and transmission belts: A transmission belt is fixedly installed on the front and rear end faces of the two third bodies 401 of the two oppositely arranged linear bearings 4. At the same time, two pulleys, a coupling, and a servo motor are installed. Since the servo motor can drive the pulleys to rotate at a constant speed through the coupling, and the transmission belt and pulley transmit power through tooth meshing, six servo motors are driven respectively. By precisely controlling the rotation speed and rotation angle of the six servo motors, the six couplings can drive the six transmission belts to move precisely left and right, thereby driving the six linear bearings 4 to move precisely left and right along the twelve guide shafts 9.

[0067] The transmission method using a combination of servo motors, couplings, gears, and racks: A rack is fixedly installed on the front and rear end faces of the two third bodies 401 of the two oppositely arranged linear bearings 4. At the same time, two gears, a coupling, and a servo motor are installed. Since the servo motor can drive the gears to rotate at a uniform speed through the coupling, and the rack and gear transmit power through tooth meshing, six servo motors are driven respectively. By precisely controlling the rotation speed and rotation angle of the six servo motors, the six racks can be driven to move left and right precisely with the help of the six couplings. In turn, the six linear bearings 4 can be driven to move left and right precisely along the twelve guide shafts 9.

[0068] The method of using the surface temperature measuring device for the straightening section of the dual-station round casting billet provided by this utility model

[0069] Step 1: Assuming that initially all three sets of ① and ② are in a relaxed configuration, that is, the eighth protrusion 503 of all three sets of ① and ② is in a vertical configuration, firstly, pass the six sets of data cables through the twelve connecting plates 8 and connect them to the six terminals 303 of the six temperature measuring guns 3. Connect the other end of the six sets of data cables to the terminal in the main control room. Then, along the twelve guide shafts 9, move the three third brackets 6 horizontally and uniformly to the left to the starting position of the measurement. Then, with O as the pivot axis, rotate all three sets of ① and ② simultaneously in a positive uniform 90-degree angle and put them in a working configuration. At this time, the eighth protrusion 503 of all three sets of ① and ② is in a horizontal configuration, and all three sets of ③ and ④ are in a vertical configuration.

[0070] Step 2: Then, along the twelve guide shafts 9, move the three third supports 6 horizontally and uniformly to the right to the end position of the measurement. During this period, the three sets of temperature measuring guns 3 can use the forward temperature measurement mode to complete the continuous surface temperature measurement of the three straightening sections AC of the three round casting billets 12. At this time, the three sets of ① and ② still maintain their working settings. Then, along the twelve guide shafts 9, move the three third supports 6 horizontally and uniformly to the left to the start position of the measurement. During this period, the three sets of temperature measuring guns 3 can use the reverse temperature measurement mode to complete the continuous surface temperature measurement of the three straightening sections CA of the three round casting billets 12.

[0071] Supplementary Explanation: The surface temperature measuring device for the straightening section of the dual-station round casting billet provided by this utility model adopts a symmetrical structure design.
