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 the straightening section of a four-flow 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 the technology of this utility model, the details of which 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

[0050] This utility model provides an assembly method for a surface temperature measuring device for a four-flow circular casting billet straightening section.

[0051] Combination Figures 1 to 19 As shown, firstly, the two second brackets 4 are arranged opposite each other, then the four linear bearings 3 are arranged opposite each other in pairs, and the sixteen fourth bosses 302 are respectively inserted into the four fifth through holes 405 of the two second brackets 4.

Then, the sixteen ends of the eight guide shafts 9 are respectively inserted into the sixteen first grooves 106 of the four first brackets 1.

[0053] Then, a base plate 2 is horizontally set, and the four first bodies 101 of the four first brackets 1 are simultaneously set on the upper surface of the base plate 2. The sixteen first screw holes 105 of the four first brackets 1 and the sixteen first through holes 201 of the base plate 2 are aligned.

[0054] Then, eight rolling bearings 11 are installed in the eight second grooves 703 of the four third brackets 7, and the four third brackets 7 are arranged in pairs facing each other.

[0057] The principle for setting the swing direction of the fourth support in the surface temperature measuring device of the four-flow round billet straightening section provided by this utility model

[0058] Combination Figure 3 and Figure 5 As shown in the top view of the present invention, for ease of description, the two fourth supports 8 arranged in opposite directions can be considered as a group, and the four fourth supports 8 can be divided into two groups. The fourth support 8 in front of the first one in each group can be defined as ①, and the fourth support 8 in the back one can be defined as ②. The four bearing segments 803 of the two fourth supports 8 can all be used as swing shafts, and can all be set to O.

[0059] like Figure 3 As shown, assuming that initially both ① and ② in each group are in a casual arrangement, that is, the tenth protrusion 802 is in a front-to-back arrangement, after simplification as follows: Figure 20 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 tenth protrusion 802 is facing left. We can define the swing direction of ① and ② as positive.

[0060] like Figure 5 As shown, assuming that initially both ① and ② in each group are in a working configuration, that is, the tenth protrusion 802 is facing left, the simplified configuration is as follows: Figure 21 As shown, along the two swing axes O, ① swings 90 degrees clockwise, while ② swings 90 degrees counterclockwise. Both ① and ② are in a relaxed configuration, that is, the tenth protrusion 802 is in a front-to-back configuration. We can define the swing directions of ① and ② as opposite.

[0061] The working principle of the surface temperature measuring device for the four-flow round casting billet straightening section provided by this utility model

[0062] Since the circular cast billet 12 is produced using a four-flow casting method, and the straightening section of the circular cast billet 12 is a horizontal and straight cylindrical structure, it can be simplified as segment AB. Figure 22 and Figure 23 As shown; combined Figure 3 and Figure 5 As shown, since the axes of the eight guide shafts 9 and the four round casting billets 12 are kept parallel to each other, under the combined action of the four linear bearings 3, the two sets of temperature measuring guns 6 arranged in opposite directions can independently complete the surface temperature measurement task of the straightening section of the four round casting billets 12.

[0063] The circular casting 12 travels from point A to point B. For the four temperature measuring guns 6, forward and reverse temperature measurement modes are respectively set. If point A is taken as the starting point and point B as the ending point, and the surface temperature of the straightening section AB is continuously measured, this temperature measurement route can be defined as the forward temperature measurement mode. Figure 22 As shown; if point B is taken as the starting point and point A as the ending point, and the surface temperature of the straightening section BA is continuously measured, this temperature measurement route can be defined as a reverse temperature measurement mode, such as... Figure 23 As shown;

[0064] In order to enable all four fourth supports 8 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 four bearing sections 803 on one side of the four fourth supports 8. 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 four servo motors respectively and precisely controlling the rotation speed and rotation angle of the four servo motors, the four fourth supports 8 can be swing precisely with the help of four couplings.

[0065] To enable precise left and right movement of all four linear bearings 3, it is advisable to group two linear bearings 3 that are arranged opposite each other. In this way, the four linear bearings 3 can be divided into two groups. Taking all factors into consideration, there are two relatively economical transmission methods that can achieve precise left and right movement of the four linear bearings 3: one is a transmission method that uses a servo motor, coupling, pulley and transmission 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 second bodies 301 of the two oppositely arranged linear bearings 3. 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, four servo motors are driven respectively. By precisely controlling the rotation speed and rotation angle of the four servo motors, the four transmission belts can be driven to move left and right precisely with the help of the four couplings. In turn, the four linear bearings 3 can be driven to move left and right precisely along the eight 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 second bodies 301 of the two oppositely arranged linear bearings 3. At the same time, two gears, a coupling, and a servo motor are installed. Since the servo motors can rotate at a constant speed through the couplings and gears, and the racks and gears transmit power through tooth meshing, four servo motors are driven respectively. By precisely controlling the rotation speed and rotation angle of the four servo motors, the four racks can be driven to move precisely left and right with the help of the four couplings. In turn, the four linear bearings 3 can be driven to move precisely left and right along the eight guide shafts 9.

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

[0069] Step 1: Assuming that initially both sets ① and ② are in a relaxed configuration, i.e., the tenth protrusion 802 of both sets ① and ② is arranged front and back, firstly, pass the four sets of data cables through the eight connecting plates 5 and connect them to the four terminals 604 of the four temperature measuring guns 6. Connect the other end of the four sets of data cables to the terminal in the main control room. Then, along the eight guide shafts 9, move the two second brackets 4 horizontally and uniformly to the left to the starting position of the measurement. Then, with O as the swing axis, swing both sets ① and ② simultaneously in a positive uniform speed by 90 degrees and arrange them in a working configuration. At this time, the tenth protrusion 802 of both sets ① and ② is arranged to the left, and the two sets of temperature measuring guns 6 are respectively facing point A of the four round casting billets 12.

[0070] Step 2: Then, along the eight guide shafts 9, move the two second supports 4 horizontally and uniformly to the right to the end position of the measurement. At this time, the two sets of temperature measuring guns 6 are respectively facing point B of the four round casting billets 12. During this period, the two sets of temperature measuring guns 6 can use the forward temperature measurement mode to complete the continuous surface temperature measurement of the four straightening sections AB of the four round casting billets 12. At this time, the two sets of ① and ② still maintain the working settings. Then, along the eight guide shafts 9, move the two second supports 4 horizontally and uniformly to the left to the starting position of the measurement. During this period, the two sets of temperature measuring guns 6 can use the reverse temperature measurement mode to complete the continuous surface temperature measurement of the four straightening sections BA of the four round casting billets 12.

[0071] Supplementary Explanation: The four-flow circular billet straightening section 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, height, and length of the circular billet. Regardless of whether forward or reverse temperature measurement mode is used, it should be ensured that the four measuring lines of the two sets of temperature measuring guns are always aligned with the four axes of the four circular billets to guarantee the validity of the measurement data. The starting position of the second support measurement refers to the point where, when both ① and ② are in working condition, both sets of temperature measuring guns are aligned with the starting point (point A) of the four circular billets.
