Description
Technical Field
[0001] This utility model belongs to the technical field of temperature measuring equipment for billet production, specifically relating to a combined surface temperature measuring device for the curved section of a round billet. 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 drive wheel rotates back and forth along the ring track, and the infrared thermometer scans and monitors the overall temperature distribution of the surface of the continuously cast billet. The signal is transmitted through a cable, and the scanning speed of the infrared thermometer is set according to the moving speed of the continuously cast billet. It can realize the scanning and monitoring of the surface temperature of the outer circumference of the continuously cast billet. Since the billet passes through the square through hole of the shell, the device is only suitable for measuring the temperature of the billet straightening section and not suitable for measuring the temperature of the billet bending section.
[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

[0045] Combination Figures 1 to 17As shown, firstly, six rolling bearings 10 are installed in the six first grooves 505 of the six third brackets 5. Then, the six third brackets 5 are divided into three groups, and the two third brackets 5 in each group are arranged opposite each other. Then, the six bearing segments 304 of the three second brackets 3 are respectively inserted into the six rolling bearings 10.

[0050] The working principle of the combined surface temperature measuring device for the curved section of a round cast billet provided by this utility model
[0051] Combination Figures 1 to 3 As shown, the six bearing segments 304 of the three second supports 3 are all swing shafts. For ease of description, let's define the highest temperature gun 2 as ① and the two bearing segments 304 of the corresponding second support 3 as point O1; define the middle temperature gun 2 as ② and the two bearing segments 304 of the corresponding second support 3 as point O2; and define the lowest temperature gun 2 as ③ and the two bearing segments 304 of the corresponding second support 3 as point O3.
[0052] Let's assume that the circular cast billet 11 uses three-strand casting. The circular cast billet 11 is continuously divided into a crystallization section AB, a curved section BE, and a straightening section EF. The crystallization section AB is a vertical and straight cylindrical structure, the curved section BE is a vertical and curved cylindrical structure, and the straightening section EF is a horizontal and straight cylindrical structure. Draw a horizontal straight line through point O2, intersecting the circular cast billet 11 at point C. Draw a vertical straight line through point O2, intersecting the circular cast billet 11 at point D. The curved section BE can then be decomposed into segments BC, CD, and DE. After simplification, as follows... Figure 18 As shown;
[0053] Combination Figure 18As shown, to simplify the operation, the vertical coordinates of points O1 and B are equal, and the horizontal coordinates of points O3 and E are equal. When all three second supports 3 are facing the same round billet 11, the angle of ∠BO1C of the second support 3 with the highest position allows the measurement of the surface temperature of segment BC by step ①; the angle of ∠CO2D of the second support 3 with the middle position allows the measurement of the surface temperature of segment CD by step ②; and the angle of ∠DO3E of the second support 3 with the lowest position allows the measurement of the surface temperature of segment DE by step ③.
[0054] Since the running route of the round billet 11 is point A → point B → point C → point D → point E → point F, two temperature measurement modes are set for the running routes of the three temperature measuring guns 2: forward temperature measurement mode and reverse temperature measurement mode. If point B is taken as the starting point and point E is taken as the ending point, and the surface temperature of the curved section BE is continuously measured, this temperature measurement route is defined as the forward temperature measurement mode; if point E is taken as the starting point and point B is taken as the ending point, and the surface temperature of the curved section EB is continuously measured, this temperature measurement route is defined as the reverse temperature measurement mode.
[0055] In the forward temperature measurement mode, the starting point is always higher than the ending point. For example, the starting point of ① is point B and the ending point is point C, the starting point of ② is point C and the ending point is point D, and the starting point of ③ is point D and the ending point is point E. That is, all three second supports 3 are in a high starting position. In the reverse temperature measurement mode, the starting point is always lower than the ending point. For example, the starting point of ① is point C and the ending point is point B, the starting point of ② is point D and the ending point is point C, and the starting point of ③ is point E and the ending point is point D. That is, all three second supports 3 are in a low starting position.
[0056] In order to achieve precise swinging of the three second supports 3, three servo motors can be installed at one end of the three swing shafts. 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 precise control of the servo motors can be achieved. Therefore, by driving three servo motors, the precise swinging of the three second supports 3 can be achieved.
[0057] The method of using the combined surface temperature measuring device for the curved section of a round cast billet provided by this utility model
[0058] Assuming that initially all three second supports 3 are in the high starting position, firstly, the three sets of data cables are passed sequentially through the three first through holes 104 of the first support 1 and the three tenth through holes 704 of the three fifth supports 7, and connected to the three terminals 203 of the three temperature measuring guns 2; then, along the six connecting rods 8, the three sets of third supports 5 are moved horizontally back and forth at a uniform speed, and simultaneously aligned with the first round casting 11; then, using O1, O2, and O3 as pivot axes, the three second supports 3 are rotated slowly and uniformly in a counterclockwise direction at angles ∠BO1C, ∠CO2D, and ∠DO3E, respectively. In this way, the three temperature guns 2 can use the forward temperature measurement mode to complete the continuous surface temperature measurement of the curved section BE of the first round casting 11; then, along the six connecting rods 8, the three sets of third supports 5 are moved horizontally back and forth at a uniform speed, and can be simultaneously facing the second round casting 11; then, with O3, O2 and O1 as the swing axes respectively, the three second supports 3 are rotated slowly and uniformly in the clockwise direction at the angles ∠EO3D, ∠DO2C and ∠CO1B, so that the three temperature guns 2 can use the reverse temperature measurement mode to complete the continuous surface temperature measurement of the curved section EB of the second round casting 11.
[0059] Supplementary Explanation: The circular billet curved section combined surface temperature measuring device provided by this utility model adopts a symmetrical structure design. The device should be designed and manufactured to match the diameter, spacing, and height of the curved section of the circular billet. Regardless of whether a forward or reverse temperature measurement mode is used, the three measuring arcs of the three temperature guns should always be aligned with the three axes of the three circular billets to ensure the validity of the measurement data. Simultaneously, the distances between the two twelfth protrusions on the eighth protrusion of the fourth bracket, the distances between the two twelfth protrusions on the ninth and tenth protrusions respectively, and the distances between the two twelfth protrusions on the two eleventh protrusions respectively should be equal so that the six connecting rods can be smoothly inserted into the twelve seventh through holes of the three sets of third brackets. To simplify the design, the relative height difference between the ninth and tenth protrusions of the fourth bracket is rationally designed so that the tilt angle of the tilted set of the third brackets is exactly 45 degrees.
