[0001] The present application relates to the technical field of online detection of difficult-to-deform strip quality, and in particular to a contact type temperature measuring guide roller. BACKGROUND

[0002] With the high-endization and specialization of aerospace, transportation and 3C products, the demand for various alloy strips is becoming more and more widespread, and the requirements for their performance indicators are also increasingly stringent. Most high alloy strips are generally high in hardness or brittleness, are easily oxidized and have uneven and coarse structures at high temperature, and are difficult to deform at room temperature and to be efficiently processed, which greatly affects the production efficiency and performance indicators of alloy strips. In order to ensure that the difficult-to-deform alloy strip is formed at high precision, high efficiency and high speed in a specific temperature range, how to implement accurate temperature control during strip production has become a problem to be studied.

[0003] In the related art, the non-contact infrared temperature measurement technology is usually used to detect the temperature of the middle part of the strip, but the temperature detection accuracy is deviated due to the influence of the on-site mist and the bright surface of the strip. SUMMARY

[0028] As described in the background, with the high-endization and specialization of aerospace, transportation and 3C products, the demand for various alloy strips is more and more extensive, and the requirements for their performance indicators are more and more demanding. In addition to high ductility metals such as copper, aluminum, gold, silver and lithium, most high alloy strips are generally high in hardness or brittleness, such as high-strength steel, stainless steel, high-silicon steel, magnesium-aluminum alloy, titanium alloy, steel-based composite strip, etc. High-temperature forming is easy to oxidize and the structure is coarse and uneven, and it is difficult to deform at room temperature and difficult to process efficiently, which greatly affects the production efficiency and performance indicators of alloy strips and greatly limits the application range of alloy strips. Fortunately, most difficult-to-deform metals can exhibit good plasticity at their respective specific temperatures, although the feasible temperature range is narrow, but if precise temperature control is implemented, it can ensure that the difficult-to-deform alloy strip is formed at a specific temperature range with high precision, high efficiency and fast speed. This special process, which is neither a hot rolling process above the recrystallization temperature nor a conventional cold rolling process, is usually called warm rolling or warm rolling process.

[0029] Up to now, whether hot rolling, warm rolling or cold rolling process, the precision temperature control of difficult deformation strip is needed to obtain good plasticity conditions and high precision shape, performance indicators, and a large amount of engineering experience has been accumulated at home and abroad. However, in engineering practice, more is to rely on offline reverse regression to adjust process parameters, which is low in efficiency and heavy in workload, resulting in large process fluctuation, unstable production process, and it is difficult to obtain stable temperature threshold space, which makes it difficult to obtain the optimal state of the above difficult deformation alloy foil strip. There are two kinds of traditional temperature control methods, one is to use non-contact infrared temperature measurement to detect the middle temperature of the strip to obtain continuous longitudinal strip temperature curve, but the temperature detection precision is deviated due to the influence of fog and bright surface of the strip, and the transverse temperature difference cannot be obtained in real time, the second is to use temperature field model for online strip temperature prediction and setting, which can obtain continuous temperature field distribution, but due to the lack of necessary temperature detection data, it is difficult to verify the accuracy of the temperature field model, and most of them are through offline temperature measurement to carry out reverse regression, which affects the real-time temperature accuracy of the online strip. Especially for difficult deformation metals such as stainless steel, high-strength steel and high-silicon steel, not only good temperature threshold space is needed, but also the edge deformation is related to the transverse temperature difference to a great extent, so the transient temperature detection of difficult deformation metals is particularly important for local shape control, and larger transverse temperature difference often leads to transverse thickness out-of-tolerance, frequent quality disputes and even serious production accidents.

[0030] Taking stainless steel and high-silicon steel as examples, the use of heating furnace preheating, furnace heating or induction heating can improve the temperature of the strip to obtain good forming characteristics, and the deformation heat and friction heat can be used in the rolling process to ensure the appropriate temperature interval. In the production process, in order to obtain good temperature law, handheld temperature measuring gun, thermocouple, imager and other devices are usually used for temperature measurement, or regression equation is used for temperature calculation. However, due to the high rolling speed and large fog, and the bright surface of the strip, using the above means, on the one hand, it is not convenient to measure online, and there is a great safety hazard, and offline measurement cannot accurately reflect the distribution state of the online temperature field, which makes the non-contact temperature measurement cannot accurately reflect the real-time temperature field distribution characteristics of the strip; on the other hand, due to the influence of the working condition, the dynamic change of the rolling parameters has a great influence on the temperature of the strip, and it is difficult to obtain high precision prediction accuracy of the temperature field model, the temperature field calculation error is very large, the real-time performance is not good, which leads to the inability to fine-tune the temperature interval, especially the inability to perceive the transverse temperature difference characteristics of the strip, which greatly affects the transverse distribution conditions of the load roll gap, and affects the control accuracy of the strip transverse thickness difference, plate crown or plate shape. Therefore, how to get the strip problem has become a hot topic of research.

[0031] The application provides a contact temperature measurement guide roller, which comprises a guide roller body, a temperature measurement device and a general processor arranged on the guide roller body, wherein the temperature measurement device comprises a temperature measurement unit arranged adjacent to the guide roller body, and a heat conduction unit arranged adjacent to one end of the temperature measurement unit away from the guide roller body; the heat conduction unit is used for transferring the heat of the measured strip to the temperature measurement unit when contacting the measured strip; and the general processor is used for receiving the first temperature generated by the temperature measurement unit according to the heat and determining the target temperature of the measured strip according to the first temperature. Thus, the heat conduction unit directly contacts the measured strip and transfers the heat, and the general processor confirms the target temperature based on the heat transferred by the heat conduction unit. Since the target temperature is obtained through direct contact with the measured strip, the temperature detection has higher accuracy and the error of strip temperature measurement is reduced compared with the non-contact infrared temperature measurement technology in the related art.

[0032] In addition, in the embodiment of the application, the contact temperature measurement guide roller comprises N temperature measurement devices, and N is a natural number. The general processor determines the target temperature of the measured strip by N times of polynomial according to the N first temperatures. Through the N first temperatures, the temperature of the strip at the position of the contact temperature measurement guide roller can be more accurately obtained, and the production parameters of the strip and the like are further controlled, or other data processing is performed.

[0033] The technical solutions of the application and how the application solves the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the application will be described below with reference to the drawings.

[0034] Figure 1 The structure of the contact temperature measurement guide roller according to some embodiments of the application is shown. As shown in the figure, the contact temperature measurement guide roller provided by the embodiment of the application comprises: Figure 1

[0035] a guide roller body;

[0036] a temperature measurement device and a general processor arranged on the guide roller body;

[0037] wherein the temperature measurement device comprises:

[0038] a temperature measurement unit arranged adjacent to the guide roller body;

[0039] a heat conduction unit arranged adjacent to one end of the temperature measurement unit away from the guide roller body;

[0040] ​The heat conduction unit is configured to, when contacting the to-be-measured strip, transfer the to-be-measured heat of the to-be-measured strip to the temperature measurement unit.

[0041] The total processor is configured to receive a first temperature generated by the temperature measurement unit according to the to-be-measured heat, and determine a target temperature of the to-be-measured strip according to the first temperature.

[0042] In some embodiments, the to-be-measured strip can be in a curved shape, and the contact temperature measurement guide roller can also be curved in a corresponding arc. The length and width of the guide roller body are not specifically limited in the present application. The temperature measurement unit can be any device capable of measuring temperature, such as a temperature sensor, a thermometer, a temperature-measurable camera, etc. The heat conduction unit can also be any device capable of conducting heat, such as a heat-conducting nut, a heat-conducting instrument, etc. After receiving the first temperature, the total processor can convert the temperature signal (usually a voltage signal) representing the first temperature into a digital or analog signal and perform further processing.

[0043] In some embodiments, the heat conduction unit can directly contact the to-be-measured strip, transfer the heat of the to-be-measured strip to the temperature measurement unit, and the temperature measurement unit can detect the temperature after receiving the heat from the heat conduction unit to obtain the first temperature and transmit the first temperature to the total processor. The target temperature is determined by the total processor according to the first temperature.

[0044] In some embodiments, the target temperature can be the first temperature itself, or can be further processed based on the first temperature. For example, when the guide roller body includes multiple temperature measurement devices, an average calculation can be performed, or the first temperature can be digitally processed by a filter, a smoothing algorithm, or other signal processing techniques to remove noise, outliers, and other possible interference factors. The target temperature can represent the instantaneous temperature of the position of the contact temperature measurement guide roller on the to-be-measured strip.

[0045] In this way, by directly contacting the to-be-measured strip through the heat conduction unit and transferring the to-be-measured heat, and by confirming the target temperature based on the to-be-measured heat transferred by the heat conduction unit, the target temperature is obtained from direct contact with the to-be-measured strip, which has higher accuracy and reduces errors in strip temperature measurement compared to related art that uses non-contact infrared temperature measurement technology to cause temperature detection to deviate.

[0046] In some embodiments, in order to facilitate aesthetics and protect the heat-conducting unit, a threaded round hole can be provided on the guide roller body. A nut-shaped heat-conducting unit, such as a heat-conducting nut, is used, and the heat-conducting unit is fixed on the guide roller body through the nut thread structure. Accordingly, at this time, the heat-conducting unit and the bottom of the round hole on the guide roller body still include a temperature measuring unit. In this way, the appearance of the guide roller body can be more harmonious and aesthetic, and the heat-conducting unit and the temperature measuring unit are arranged in the round hole, which can better protect the heat-conducting unit and the temperature measuring unit.

[0047] In some embodiments, in order to enable the heat-conducting unit and the temperature measuring unit to be more firmly fixed in the round hole of the guide roller, the contact temperature measuring guide roller further comprises a fixing member provided between the temperature measuring device and the guide roller body. The fixing member not only has the function of fixing, but also has the function of adjusting the tightness. In some embodiments, the contact area of the temperature measuring element and the rolled piece can be adjusted according to actual needs, so as to meet different temperature measuring accuracy requirements. When higher temperature measuring accuracy is required, the fixing member can be tightened to increase the contact area of the temperature measuring element and the rolled piece, so that the temperature measurement is more stable and accurate. Conversely, if the temperature measuring accuracy requirement is reduced, the fixing member can be appropriately loosened to reduce the contact area.

[0048] In some embodiments, the fixing member can be a pre-tightening spring provided between the temperature measuring unit and the guide roller body, which applies a pre-tightening force to the temperature measuring unit to ensure close contact between the temperature measuring unit and the heat-conducting unit, thereby improving the accuracy and stability of temperature measurement. The fixing member can also be in the form of a screw to fix the temperature measuring unit and the heat-conducting unit.

[0049] In some embodiments, due to the high temperature to be measured, the contact temperature measuring guide roller further comprises a high-temperature-resistant shielding cable provided between the temperature measuring unit and the processor; and a cable conduit wrapped outside the high-temperature-resistant shielding cable. The high-temperature-resistant shielding cable is a special cable that can work normally in a high-temperature environment and has good shielding performance to reduce the influence of external interference on signal transmission, so that the first temperature obtained by the temperature measuring unit can be accurately transmitted to the total processor.

[0050] In some embodiments, the temperature measuring unit and the high-temperature-resistant shielding cable can be connected by welding or through a connector. The connector is used to connect the interface parts of the temperature measuring element and the high-temperature-resistant shielding cable to ensure that the temperature signal representing the first temperature can be stably and reliably transmitted.

[0051] In some embodiments, in order to better protect the contact temperature measuring guide roller as a whole and each unit, the contact temperature measuring guide roller further comprises a wear-resistant coating wrapped outside the guide roller body, which is used to improve the wear resistance of the guide roller, prolong the service life of the contact temperature measuring guide roller provided by the embodiments of the application, and ensure the efficiency of temperature transmission.

[0052] In some embodiments, the contact temperature measuring guide roller further comprises a wireless transmitter electrically connected to the total processor; and an antenna electrically connected to the wireless transmitter. After obtaining the target temperature, the total processor can cooperate with the wireless transmitter and the antenna to transmit the target temperature processed by the total processor through wireless means, so as to realize remote transmission of data. For example, the target temperature can be synchronously transmitted to a 3C (mobile phone, notebook, tablet) PC server through the wireless transmitter and the antenna, so as to display a real-time temperature curve, meet the real-time monitoring, display and printing of online temperature. In addition, the real-time detected temperature curve can be used to predict the working condition, give an early warning of deviation and realize closed-loop control by using the warm rolling process model of the PC server, so as to meet the high-precision regulation and control requirements of the strip steel transverse temperature difference, shape state, edge deformation and roll gap shape.

[0053] In some embodiments, the contact temperature measuring guide roller comprises N temperature measuring devices, and N is a natural number. N can be an odd number, so that the temperature measuring device is arranged at the middle of the contact temperature measuring guide roller, and the temperature measured by the contact temperature measuring guide roller is more accurate.

[0054] In some embodiments, the total processor can determine the target temperature of the measured strip according to N first temperatures, so as to realize transverse temperature synchronous measurement of the contact temperature measuring guide roller. For example, the temperature detection value of the i th temperature measuring device can be set as T i (i = 1, 2, …, N), and the following method can be used to represent the current strip transient temperature, where ξ i is an online calibrated process correction coefficient, which needs to comprehensively consider the wall thickness, speed, cooling, interface heat conduction and other factors, and the specific calculation process can be as follows formula (1):

[0055]

[0056] Further, the number set (the transient temperature values of the i th temperature measuring device on the contact temperature measuring guide roller) obtained based on formula (1) is used to synchronously fit the temperature detection values of all temperature measuring devices by using a polynomial of at least the second degree. The transverse coordinate y i of the i th temperature measuring device relative to the contact temperature measuring guide roller is obtained, and the curve formula (2) representing the detection value of the i th temperature measuring device and the position (i.e., the position of the temperature measuring device relative to the contact temperature measuring guide roller) is obtained based on formula (1):

[0057]

[0058] Wherein, a N is an empirical coefficient, which can be preset by manual or calculated by a self-learning large model, and the embodiments of the present application do not make specific limitations.

[0059] In some embodiments, after obtaining the target temperature, the total processor can apply the target temperature to the production process of the measured strip, such as the following process:

[0060] Deformation thermal effect synergy model: based on the transverse temperature difference (i.e., formula (2)), the plate shape and crown mechanism model is finely processed, and based on machine learning or other advanced algorithms, a thermal effect synergy model of plate shape and crown is constructed to realize high-precision prediction of the deformation process of difficult-to-deform strip. Coupling the elastic model of the roller system and the metal deformation model, the plate shape F and the crown C are calculated synergistically, and the corresponding weighting factors and are set respectively to obtain the optimal regulation and control effect of the plate shape and crown. The specific calculation process can be as follows formula (3):

[0061] f = Min (γ1F + γ2C)

[0062] Remote real-time communication: ensure fast digital processing and remote stable transmission of strip three-dimensional transient temperature, real-time synchronous transmission and three-dimensional display between mobile phones and computer terminal devices.

[0063] Temperature closed-loop control: according to the thermal effect deformation result considering the transverse temperature change, the rolling process parameters are automatically adjusted to realize the automatic closed-loop control of the best rollable temperature threshold or deviation of the difficult-to-deform strip, so as to obtain the best temperature curve of the corresponding contact type temperature measurement guide roller. The specific calculation process can be as follows formula (4).

[0064]

[0065] In order to better understand the contact type temperature measurement guide roller provided by the embodiments of the present application, examples are given, and it should be understood that the examples are not limiting. Figure 2 The front view structure of the contact type temperature measurement guide roller according to some embodiments of the present application is shown, Figure 3 The side view structure of the contact type temperature measurement guide roller according to some embodiments of the present application is shown. As Figure 2 and Figure 3As shown, the contact temperature measuring guide roller mainly includes a contact temperature measuring guide roller 1, a wear-resistant coating 2, a heat-conducting nut 3 (i.e., the heat-conducting unit mentioned above), a temperature measuring element 4 (i.e., the temperature measuring unit mentioned above), a high-temperature resistant shielded cable 6, a preloaded spring 7, a signal processor 9 and a wireless transmitter 10. During operation, the strip temperature is quickly transmitted to the heat-conducting nut 3 embedded in the guide roller 1 through the wear-resistant coating 2. After the temperature measuring element 4 senses the transient temperature in real time, it transmits the signal to the signal processor 9 through the connector 5 and the high-temperature resistant shielded cable 8. Finally, the signal is transmitted to the server using the wireless signal transmitter 10 and the antenna 11, completing the real-time detection process of the online strip temperature signal, which is displayed and printed synchronously with the rolling signal, meeting the high-precision strip temperature measurement and control requirements of difficult-to-deform strips, and providing real-time online temperature data for further optimizing the warm rolling process of difficult-to-deform strips.

[0066] In order to obtain Figure 2 and / or Figure 3 The contact temperature measuring guide roller shown in the manufacturing process is firstly drilled in the middle of the contact temperature measuring guide roller 1, and a series of threaded T-shaped circular holes are drilled on its surface, usually in odd numbers, to ensure that there is a detection unit in the middle of the roller body; then the high-temperature resistant shielded cable 6, preload spring 7, temperature measuring element 4 (with connector 5) and thermal nut 3 of each detection unit are sequentially embedded in the T-shaped circular hole, wherein the thermal nut 3 is tightened by the threaded connection with the T-shaped circular hole, and the preload spring 7 applies a preload force to the temperature measuring element 4 to ensure close contact and rapid heat conduction; after fixing the above components, the high-temperature resistant shielded cable 6 of each temperature measuring element 4 is guided to the signal processor 9 on one side of the contact temperature measuring guide roller 1 through the cable guide 8, the signal processor 9 is connected to the shaft head of the guide roller 1 by screws, the wireless signal transmitter 9 is hard-connected to the signal processor 10, and is connected to the external antenna 11; finally, the wear-resistant coating 2 is coated on the surface of the contact temperature measuring guide roller 1 to form a complete structural assembly.

[0067] In getting Figure 2 and / or Figure 3 The contact temperature measuring guide roller shown can be used. Figure 4 FIG. 4 shows a temperature detection process according to some embodiments of the present invention, such as Figure 4 As shown, the contact temperature measuring guide roller provided in the embodiment of the present invention can be used in the process shown in the following steps:

[0068] 1. Data Collection: Temperature data is collected in real time using temperature measurement units installed on contact-type temperature-measuring guide rollers. These sensors convert transient temperature signals into electrical signals for subsequent processing.

[0069] 2. Signal digital processing: The collected transient temperature signals are first subjected to digital processing using a signal processor (i.e., total processor) connected to the contact temperature measurement guide roller shaft end, removing noise, outliers, and other possible interference factors through filters, smoothing algorithms, or other signal processing techniques.

[0070] 3. Remote data display of temperature signals: The processed temperature data is remotely displayed to the user in the form of graphs or other visualizations through mobile phones, computers, and other terminal devices, providing real-time feedback to help operators and engineers monitor the rolling process in real time and respond quickly to any abnormal situations.

[0071] 4. Digital device display, such as PC display, mobile phone display, and tablet display. In addition, these temperature data can also be applied in actual production processes, such as the following ways:

[0072] Plate shape and crown prediction: The processed transient temperature data is imported into a pre-established plate shape and crown prediction model, and based on neural networks, regression analysis, and other machine learning algorithms, the measured transient temperature data can be used to accurately predict the trend of plate shape and crown changes online.

[0073] Rolling process parameter adjustment: Based on the prediction results of plate shape and crown, the system automatically or manually adjusts rolling process parameters such as rolling force, rolling speed, roll gap, etc., to maintain the stability and consistency of the strip during rolling.

[0074] Quality control: Based on the transient temperature distribution law, especially the transverse temperature difference characteristics, real-time adjustment of rolling process parameters is made to improve strip quality, reduce scrap rate, and improve production efficiency and economic benefits.

[0075] The contact temperature measurement guide roller provided by the embodiment of the present application can achieve high-precision contact measurement of the online temperature of difficult-to-deform strips, especially the transverse temperature difference, provide real-time transverse temperature curve for hot rolling and warm rolling processes, and based on efficient and stable transmission of remote temperature data, perform plate shape and crown error compensation of the transverse temperature difference, thereby improving the control precision of thermal effect deformation of difficult-to-deform strips, performing real-time online monitoring and closed-loop control, greatly improving the convenience of the rolling production process, and helping to improve the plate shape and crown core indicators of difficult-to-deform strips and reduce manual operation.

[0076] In addition, the contact temperature measurement guide roller provided by the embodiment of the present application also has the following advantages:

[0077] 1. The temperature measurement element is embedded with a strip nut on the surface of the guide roller, so that the temperature measurement element on the surface of the roller can directly contact the rolled piece during rolling, achieving contact temperature measurement. This direct contact method ensures the accuracy of temperature measurement and overcomes the errors that may exist in traditional temperature measurement methods.

[0078] 2. The temperature measuring element on the guide roller is fixed by spring and screw fixing members, which have the function of adjusting the tightness. This design allows users to adjust the contact area between the temperature measuring element and the rolled piece according to actual needs, so as to meet different temperature measuring accuracy requirements. When higher temperature measuring accuracy is required, the fixing member can be tightened to increase the contact area between the temperature measuring element and the rolled piece, so that the temperature measurement is more stable and accurate. Conversely, if the requirement for temperature measuring accuracy is reduced, the fixing member can be appropriately loosened to reduce the contact area.

[0079] 3. In the rolling process of difficult-to-deform metals, this new type of temperature measuring device can accurately monitor the temperature change of the rolled piece in real time, providing important data support for the optimization and control of the rolling process, and helping to improve the rolling quality and efficiency.

[0080] 4. Through the processing of the signal processor, the transverse temperature data is converted into digital signals and transmitted remotely through a dedicated communication protocol. This transmission method has the advantages of fast speed, good stability, strong anti-interference ability, etc., which can ensure the real-time and accuracy of the data. The remotely transmitted data can be directly transmitted to the shape and crown model, providing real-time and accurate temperature data support for the calculation and prediction of the model.

[0081] 5. The shape and crown model is a key link in controlling the rolling quality of the strip. By receiving the temperature data from the signal processor as the initial condition or real-time parameter, it is substituted into the shape and crown model. The model can calculate the transverse temperature difference of the strip online, and compensate the shape error synchronously according to the temperature difference. This compensation method can adjust the rolling parameters in real time to reduce or eliminate the shape error caused by temperature difference, so as to improve the rolling precision and surface quality of the strip.

[0082] 6. Compared with traditional non-contact temperature measuring instruments, the contact temperature measuring method of the present application has high precision and is more convenient to use in high-speed, high-temperature and high-humidity environments, and can obtain the online characteristics of the temperature field in real time, providing high-precision temperature evolution trend and transverse temperature difference conditions for the shape and crown model to meet the high-precision warm rolling process requirements of difficult-to-deform metals such as difficult-to-deform strips and stainless steel. Especially for high-precision detection and control of strip edge temperature, it provides a better rolling environment compared with traditional temperature measuring methods.

[0083] The embodiments of the present application combine sensor technology, signal processing technology, computer technology and advanced prediction models to realize high-precision rolling control and improve the quality of the strip.
