[0002] The mold is used to cool the molten steel and preliminarily solidify it into a desired shape, such as a slab or a billet.

Obviously, the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present application belong to the scope of protection of the present application.

In the following description, numerous specific details are provided to give a thorough understanding of the embodiments of the present application. However, those skilled in the art will realize that the technical solutions of the present application may be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted. In other cases, well-known methods, devices, implementations, or operations are not shown or described in detail to avoid obscuring aspects of the present application.

[0045] The block diagrams shown in the drawings are only functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different models and / or processor devices and / or microcontroller devices.

[0046] The flowcharts shown in the drawings are only illustrative and do not necessarily include all the content and operations / steps, nor are they necessarily executed in the order described. For example, some operations / steps may be decomposed, while some operations / steps may be combined or partially combined, so the actual execution order may change according to the actual situation.

[0047] It should also be noted that the terms "first", "second", etc. in the specification, claims, and above-mentioned drawings of the present application are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that the objects so used may be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described.

[0048] In the steel manufacturing process, especially in continuous manufacturing processes, a mold is used to cool and preliminarily solidify molten steel into the desired shape, usually in the form of a slab or a billet. Therefore, in continuous casting production of steel, the stable operation of the continuous casting mold is of great significance to the quality of the cast billet and the continuity of production.

[0049] In order to detect the operating state of the mold, several thermocouples are usually set at different positions on the outer wall of the mold, such as hundreds of thermocouples. By detecting the temperature change on the mold through the thermocouples, it is determined whether the mold is abnormal. For example, it is determined whether problems such as sticking or steel leakage occur through the temperature change. It can be seen that the stable operation of the thermocouple itself is the premise for accurately detecting the operating state of the mold. Whether the temperature measurement data of the thermocouple is accurate is directly related to the judgment of the continuous casting automatic control system. Once there is a deviation in the temperature measurement data, it will interfere with the automatic control, affect the quality of the cast slab, and even cause production accidents in severe cases. Therefore, it is necessary to detect whether there is an abnormality in the thermocouple itself. Among them, the situations where the thermocouple itself has an abnormality include but are not limited to abnormal sensitivity, thermocouple damage, etc.

[0050] Currently, the temperature measurement data of the thermocouple is mainly obtained by heating the mold, and it is determined whether there is an abnormality in the thermocouple according to the temperature measurement data. The main way to heat the mold is by using a torch. Torch heating is that after the mold is repaired, an operator uses a flame cutting torch to heat the copper plate of the mold, and it is determined whether there is an abnormality by observing the change in the temperature measurement data of each thermocouple. However, the method of torch heating can only heat the thermocouples in some areas and cannot make all thermocouples heat simultaneously. The detection time is long and the detection efficiency is low, which affects the production efficiency.

[0051] As can be seen from the above, there are many deficiencies in the existing mold thermocouple detection methods, which cannot meet the requirements of high-efficiency and accurate detection in steel continuous casting production. In view of this, the embodiments of the present application provide a mold thermocouple detection system, which can reduce the detection time of the mold thermocouple to a certain extent and improve the detection efficiency.

[0052] The mold thermocouple detection system of the embodiments of the present application will be described below with reference to specific drawings.

[0053] Figure 1 shows the structural block diagram of the mold thermocouple detection system in the embodiments of the present application; Figure 2 shows the front view of the heating device in the embodiments of the present application; Figure 3 shows the side view of the heating device in the embodiments of the present application; Figure 4 shows the top view of the heating device in the embodiments of the present application.

[0054] Combined with Figures 1 to 4, according to the first aspect of the embodiments of the present application, a mold thermocouple detection system is provided. The mold includes a first cavity, and a plurality of thermocouples are provided on the outer wall of the first cavity. The system includes: a heating device 1 and a controller 2. The heating device 1 is configured to be disposed in the first cavity of the mold. The heating device 1 includes a plurality of heating plates 11, and each heating plate 11 is disposed facing one of the inner walls of the first cavity. The controller 2 is electrically connected to the heating device 1, and the controller 2 is configured to control each heating plate 11 of the heating device 1 to uniformly heat each inner wall of the first cavity. During the process of the temperature of each inner wall rising, the temperature measurement data of the target thermocouple is obtained, and based on the temperature measurement data, it is determined whether the target thermocouple is abnormal.

[0055] It should be noted that a mold generally includes a cavity, a shell, and a cooling system. In the continuous casting process, the cavity is used to hold molten steel and the cavity is open at both the top and bottom. The cavity is made of copper plates, and a cooling system (including water cooling channels, water inlets and outlets, etc.) is provided between the cavity and the shell for heat exchange with the molten steel in the cavity.

[0056] In the embodiments of the present application, by disposing the heating device 1 in the first cavity of the mold and each heating plate 11 facing one inner wall of the first cavity, each inner wall of the first cavity can be uniformly heated by each heating plate 11. Thus, based on the principle of heat conduction, the heat is conducted to the outer wall of the mold and detected by the thermocouple. Therefore, it can be determined whether the thermocouple is abnormal according to the temperature measurement data of the thermocouple. Since the same heating device 1 can be used to uniformly heat the mold, each thermocouple can measure the temperature simultaneously. Thus, the abnormal detection of multiple thermocouples can be realized based on one heating, reducing the detection time of the mold thermocouple and improving the detection efficiency, thereby not affecting the production efficiency of the steel billet.

[0057] In some embodiments, the heating device 1 further includes: a second cavity 12 and a support member. The heating plates 11 are disposed on the outer wall of the second cavity 12; the support member includes a disk 13, a screw 14, and a scissor frame 15. The disk 13 is disposed above the second cavity 12. The first end of the screw 14 is connected to the disk 13, and the second end of the screw 14 passes through the top of the second cavity 12 and extends into the second cavity 12. The scissor frame 15 is rotatably connected to the second end of the screw 14. Wherein, when the disk 13 rotates to drive the screw 14 to rotate to a preset position, the scissor frame 15 expands and presses the heating plate 11 so that the heating plate 11 abuts against the inner wall of the first cavity.

[0058] It should be noted that there can be multiple scissor frames 15, such as 2, 4, etc. Each scissor frame 15 can include multiple connecting rods, such as two connecting rods. The connecting rods are connected by hinges to form an "X" - shaped structure. When the scissor frame 15 expands, it can provide a height change in the vertical direction (the height direction of the second cavity 12). When the scissor frame 15 contracts, the height of the scissor frame 15 can be reduced. On this basis, the screw 14 is used to drive the expansion and contraction of the scissor frame 15. The screw 14 passes through the top of the second cavity 12 and extends into the second cavity 12. The first end of the screw 14 close to the wheel disc 13 can be relatively fixed, and the second end of the screw 14 is connected to the key node of the scissor frame 15, such as being connected to a slider or a moving support point at the bottom of the scissor frame 15. When the wheel disc 13 rotates, the wheel disc 13 drives the screw 14 to rotate. When the screw 14 rotates, it can push or pull this node, thereby changing the expansion and contraction state of the scissor frame 15. For example, when the screw 14 rotates clockwise or counter - clockwise, due to the existence of the thread on the screw 14, the screw 14 will rotate along its own axis. If the screw 14 is connected to the key node of the scissor mechanism (such as the slider at the bottom), then the axial movement of the screw 14 will be directly converted into the horizontal movement of the scissor frame 15. Thus, in the embodiment of the present application, when the wheel disc 13 rotates to drive the screw 14 to rotate to a preset position, the scissor frame 15 expands and presses the heating plate 11, so that the heating plate 11 can abut against the inner wall of the first cavity, and thus the heating plate 11 can heat the first cavity at zero distance, improving the heating efficiency and the uniformity of heating.

[0059] In some embodiments, openings are provided at the top and bottom of the mold, and the width of the openings is greater than the width of the outer wall of the second cavity 12; the heating device 1 further includes: a support frame 16, arranged above the second cavity 12, and the width of the support frame 16 is greater than the width of the openings.

[0060] It can be understood that in the continuous casting steel process, the top and bottom of the mold are open so that the molten steel can continuously pass through. On this basis, in order to stably install the heating device 1 in the first cavity of the mold, a support frame 16 is arranged above the second cavity 12, and the width of the support frame 16 is greater than the width of the openings, so that the heating device 1 is suspended in the first cavity, realizing the installation of the heating device 1.

[0061] In some embodiments, the heating device 1 further includes: leveling bolts 17, arranged on the support frame 16 and configured to maintain the balance of the support frame 16. Exemplarily, the support frame 16 is a support flat plate, and there are 4 leveling bolts 17, evenly distributed around the perimeter of the support flat plate, thereby maintaining the stability of the support frame 16 and improving the structural stability.

[0062] In some embodiments, the second cavity 12 is filled with an internal heat insulation material. Exemplarily, the heat insulation material may be mica material, rock wool, polystyrene foam, polyurethane foam, aerogel, etc.

[0063] Thus, by filling the heat insulation material in the second cavity 12, when the heating plate 11 is heated, the heat is conducted unidirectionally to the first cavity of the mold and will not enter the interior of the second cavity 12, thereby further improving the temperature rise uniformity of each heating plate 11 and the heating efficiency.

[0064] In some embodiments, heating wires are provided in the heating plate 11. The heating wires have a high resistivity and are made of materials such as nickel-chromium alloy (Nichrome), iron-chromium-aluminum alloy (FeCrAl), etc.

[0065] According to the working principle of the heating wire, based on the electrothermal effect, that is, when an electric current passes through a conductor with a certain resistance, according to Ohm's law, a voltage drop will be generated across the conductor, thereby generating heat. This phenomenon also follows Joule's law, which states that when an electric current passes through a conductor, due to the resistance inside the conductor, electrons will collide with the conductor atoms during movement, resulting in the release of energy in the form of heat. The greater the current, the higher the resistance, or the longer the power-on time, the more heat is generated. Thus, the first cavity of the mold can be heated by using the heating wire.

[0066] In some embodiments, the heating device 1 further includes a temperature-measuring thermocouple 18, which is used to detect the temperature on the heating plate 11, so as to provide the controller 2 for PID (Proportional Integral Derivative) closed-loop control.

[0067] It can be understood that when the controller 2 controls the heating plate 11 to uniformly heat each cavity of the first cavity, the temperature rise conditions of each heating plate 11 are basically the same, that is, the heating device 1 is a constant-temperature heating device 1, so that the temperatures detected by each thermocouple on the first cavity are basically the same, which is convenient for subsequent observation of whether there is an abnormality in the thermocouple.

[0068] In some embodiments, the heating device 1 is further provided with a contact terminal 19 for connecting a power supply to enable the heating plate 11 to operate.

[0069] Based on the above - disclosed content, in the embodiment of the present application, by arranging the heating device 1 in the first cavity of the crystallizer and orienting each heating plate 11 towards an inner wall of the first cavity, it is possible to uniformly heat each inner wall of the first cavity by using each heating plate 11. Thus, based on the principle of heat conduction, the heat is conducted to the outer wall of the crystallizer and detected by the thermocouple. Therefore, it is possible to determine whether the thermocouple is abnormal according to the temperature - measuring data of the thermocouple. Since the same heating device 1 can be used to uniformly heat the crystallizer, each thermocouple can measure the temperature simultaneously. Thus, the abnormal detection of multiple thermocouples can be achieved based on one - time heating, reducing the detection duration of the thermocouples of the crystallizer and improving the detection efficiency, thereby not affecting the production efficiency of the billet. The heating plate 11 is extruded by the scissor lift 15 so that the heating plate 11 can be in contact with the inner wall of the first cavity, so that the heating plate 11 can heat the first cavity at zero distance, improving the heating efficiency and the uniformity of heating. By filling the second cavity 12 with heat - insulating materials, the heating plate 11 conducts one - way heating on the first cavity of the crystallizer, improving the heating uniformity and heating efficiency.

[0070] Figure 5 Fig. shows the flowchart of the method for detecting the thermocouple of the crystallizer in the embodiment of the present application; Figure 6 Fig. shows another flowchart of the method for detecting the thermocouple of the crystallizer in the embodiment of the present application.

[0071] According to the second aspect of the embodiment of the present application, there is provided a method for detecting the thermocouple of a crystallizer, which is applied to a controller in the thermocouple detection system of the crystallizer as described in any one of the first aspects, for example, a PLC (Programmable Logic Controller), and the method includes but is not limited to:

[0072] Step S10. Control each heating plate of the heating device to uniformly heat each inner wall of the first cavity;

[0073] It can be understood that controlling each heating plate to uniformly heat each inner wall of the first cavity means that the temperature - rise situations of each heating plate are basically the same, so that the temperature - rise situations of each inner wall of the first cavity are basically the same. That is, theoretically, the temperature - measuring data of each thermocouple should be basically the same. Thus, subsequently, it can be determined whether the thermocouple is abnormal according to whether the temperature - measuring data of the thermocouple conforms to the above - mentioned basically the same situation.

[0074] Step S20. During the process of the temperature rise of each inner wall, obtain the temperature - measuring data of the target thermocouple, and determine whether the target thermocouple is abnormal according to the temperature - measuring data.

[0075] It can be understood that during the process of the inner walls of the first cavity heating up, based on the principle of heat conduction, the outer walls of the first cavity will also heat up, and thus the temperature measurement data can be detected by each thermocouple.

[0076] It should be noted that in order to ensure the stable operation of the mold, the sensitivity or whether it is damaged of each thermocouple set on the mold can be detected. Therefore, the target thermocouple can be one of multiple thermocouples, or any one of them.

[0077] In some embodiments, determining whether the target thermocouple is abnormal according to the temperature measurement data includes:

[0078] Step S201. Determine whether the temperature measurement data meets a preset temperature rise rate condition, where the preset temperature rise rate condition includes: the temperature rise rate of the temperature measurement data is within a preset range;

[0079] It can be understood that in the case of a normal thermocouple, the temperature rise rate reflected by the temperature measurement data of the thermocouple should meet the preset temperature rise rate condition, that is, within the preset range, such as rising 20 - 30 degrees per minute, etc. If the temperature measurement data of the thermocouple is not within this preset range, it indicates that the thermocouple is abnormal, such as abnormal sensitivity. If the temperature measurement data of the thermocouple is within this preset range, it indicates that the sensitivity of the thermocouple may be okay.

[0080] Step S202. If the temperature measurement data does not meet the preset temperature rise rate condition, determine that the target thermocouple is abnormal.

[0081] In some embodiments, after determining whether the temperature measurement data meets the preset temperature rise rate condition, the method further includes:

[0082] Step S203. If the temperature measurement data meets the preset temperature rise rate condition, determine whether the temperature measurement data meets a preset temperature difference condition, where the preset temperature difference condition includes: the temperature difference between the target thermocouple and the surrounding thermocouples is less than or equal to a temperature difference threshold;

[0083] If the temperature measurement data of the thermocouple is within this preset range, it indicates that the sensitivity of the thermocouple may be okay, but to ensure the accuracy of the test results. Further determine whether the thermocouple is abnormal according to whether the temperature measurement data meets the preset temperature difference condition. Ideally, since the first cavity of the mold is heated uniformly, the temperature data detected by each thermocouple at a certain moment should be basically the same in theory, such as the temperature difference not exceeding 2 degrees. If the temperature difference between the temperature measurement data of a certain thermocouple and the temperature measurement data of its surrounding thermocouples exceeds the threshold, it indicates that this thermocouple may be damaged and is abnormal.

[0084] Step S204. If the temperature measurement data does not meet the preset temperature difference condition, it is determined that the target thermocouple is abnormal; otherwise, the target thermocouple is normal.

[0085] In some embodiments, after determining whether the target thermocouple is abnormal according to the temperature measurement data, the method further includes:

[0086] Step S30. If the target thermocouple is abnormal, an early warning prompt for the abnormal state of the target thermocouple is given according to the preset position identifier of the target thermocouple.

[0087] In some embodiments, the PLC controller can also be connected to a display terminal, and the display terminal can be a touch display screen. In the embodiments of the present application, each thermocouple provided on the outer wall of the mold can be numbered according to its position, so that each thermocouple has a corresponding position identifier. When the target thermocouple is abnormal, an early warning prompt for the abnormal state of the target thermocouple can be given according to the preset position identifier, for example, by means of sound and light alarm, highlighting display, etc. for alarm. Thus, the position where the abnormal thermocouple is located can be quickly located, and the maintenance efficiency can be improved.

[0088] According to the third aspect of the embodiments of the present application, a computer-readable storage medium is provided. At least one computer program instruction is stored in the computer-readable storage medium, and the at least one computer program instruction is loaded and executed by a processor to implement the operations performed by the method according to any one of the first aspects.
