Description

TECHNICAL FIELD

[0001] The present application relates to the field of water cooling control, in particular to a steel plate water cooling control method and related equipment. BACKGROUND

[0002] TMCP (thermo-mechanical control process) is a technology that aims to refine grains and strengthen the fine grains. In the development history of TMCP, the first thing people realized was controlled rolling. The core idea is to control the hardening state of austenite, that is, to accumulate a large amount of energy in austenite through deformation, and try to obtain austenite in a hardening state during rolling to prepare for grain refinement in the subsequent phase change process. In order to break through the limitations of controlled rolling and further strengthen the performance of steel, on the basis of controlled rolling, controlled cooling technology has been developed. Among the many influencing factors, post-rolling water cooling is the key to affecting the target organization transformation of TMCP steel plate, and directly determines the performance of the steel plate.

[0003] The traditional evaluation of the final cooling temperature is a linear data collection method, which collects the temperature at the middle position of the steel plate as the judgment temperature of the final cooling temperature of the steel plate. This evaluation method cannot fully represent the temperature uniformity of the TMCP steel plate, so the performance test results of the steel plate and the final cooling temperature parameter cannot establish a good matching relationship.

Rather, these embodiments are provided so that the present application can be more thoroughly understood, and the scope of the present application can be accurately conveyed to those skilled in the art.

[0035] To solve the problem that the detection and control method of the steel plate water cooling numerical value in the prior art is too single, the embodiments of the present application provide a steel plate water cooling control method, as shown in Figure 1 The method comprises the following steps.

[0036] S101, obtaining the overall final cooling temperature distribution of a target steel plate after water cooling;

[0037] Exemplarily, a temperature detection system is added after the post-rolling water cooling equipment to obtain the temperature distribution of the overall plate surface of the steel plate, which is used to represent the final cooling temperature distribution of the steel plate after water cooling. Compared with the method of collecting the temperature of the middle part of the steel plate as a representation of the final cooling temperature of the steel plate, the present scheme can more comprehensively evaluate the temperature uniformity of the steel plate based on the overall final cooling temperature.

[0038] S102, determining the final cooling temperature uneven type of the target steel plate based on the overall final cooling temperature distribution of the target steel plate after water cooling;

[0039] Exemplarily, based on the overall final cooling temperature distribution of the target steel plate after water cooling, it can be determined where the water cooling is excessive and the temperature is too low, and where the water cooling is insufficient and the temperature is too high, so as to determine the final cooling temperature uneven type of the target steel plate, which facilitates the further implementation of the subsequent method.

[0040] S103, process solidification based on the final cooling temperature uneven type of the target steel plate.

[0041] Exemplarily, for the case that the water cooling is excessive and causes the temperature to be too low, or the water cooling is insufficient and causes the temperature to be too high, the process solidification is performed, so that the final cooling temperature of the steel plate can reach the expected temperature. Based on the uniformity of the final cooling temperature of the whole plate and the type of the non-uniform final cooling temperature, the water cooling process of the steel plate can be optimized, and the effect of the improved process can be comprehensively evaluated, so as to targetly improve the hit rate and uniformity of the final cooling temperature of the whole plate.

[0042] By the above technical solution, the steel plate water cooling control method provided by the present application can solve the problem that the detection and control method of the steel plate water cooling value in the prior art is too single. The present application obtains the overall final cooling temperature distribution of the target steel plate after water cooling; determines the type of the non-uniform final cooling temperature of the target steel plate based on the overall final cooling temperature distribution of the target steel plate after water cooling; and performs process solidification based on the type of the non-uniform final cooling temperature of the target steel plate. In the above solution, the overall temperature distribution of a steel plate after water cooling is determined, and the non-uniform temperature distribution of the steel plate after final cooling is determined based on the overall temperature distribution of the steel plate, that is, where the water cooling is excessive and where the water cooling is insufficient. The water cooling process of the steel plate is optimized based on the determined non-uniform temperature distribution of the steel plate, so that the water cooling process of the steel plate can be optimized based on the overall steel plate, the steel plate subjected to water cooling can continuously receive the optimized water cooling process, a one-to-one correspondence between the overall steel plate and the final cooling temperature is established, and the relationship between the water cooling process and the performance of the steel plate is more objectively and truly reflected. At the same time, the present application improves the uniformity of the final cooling temperature, further improves the uniformity of the overall performance of the steel plate, and is beneficial to improving the yield of the steel plate and the safety during use.

[0043] In one embodiment, the obtaining of the overall final cooling temperature distribution of the target steel plate after water cooling comprises:

[0044] The overall final cooling temperature distribution of the target steel plate after water cooling is obtained based on a thermal imaging device.

[0045] Exemplarily, the thermal imaging device can be an infrared thermal imager system. With the development of detection technology, the steel plate full-plate temperature detection method has achieved a breakthrough. The infrared thermal imager is used to reflect the infrared radiation energy distribution pattern of the measured target to the photosensitive elements of the infrared detector through the infrared detector and the optical imaging objective, so as to obtain the infrared thermal imaging diagram. The thermal imaging diagram corresponds to the thermal distribution of the object surface. The obtained thermal imaging diagram is introduced into the computer to obtain the temperature data of any position of the photographed image by using special analysis software.

[0046] Exemplarily, the method prevents the infrared thermal imaging system on the steel plate production line, which is installed at the outlet of the water cooling device, from measuring the final cooling temperature of the water-cooled steel plate, obtaining the thermal image of the final cooling temperature of the whole plate surface of the steel plate, obtaining the distribution data of the final cooling temperature of the whole plate surface of the steel plate by using the image processing software, and determining the overall final cooling temperature distribution of the target steel plate after water cooling.

[0047] In an embodiment, the final cooling temperature unevenness type of the target steel plate includes at least one of head-tail temperature unevenness, edge temperature unevenness, local temperature unevenness, and wave-shaped temperature unevenness.

[0048] Exemplarily, after obtaining the thermal image of the final cooling temperature of the whole plate surface of the water-cooled steel plate by using the infrared thermal imaging system of the production line, the distribution data of the final cooling temperature of the whole plate surface of the steel plate is obtained by using the image processing software, and the typical final cooling temperature unevenness is divided into four categories: head-tail temperature unevenness, edge temperature unevenness, local temperature unevenness, and wave-shaped temperature unevenness. The head-tail temperature unevenness refers to the final cooling temperature within 1000mm of the head or tail of the steel plate (the direction of entering the water cooling area first is the head, and the direction of entering the water cooling area later is the tail) being lower than or higher than the target final cooling temperature by 50℃ or more; the edge temperature unevenness refers to the final cooling temperature within 200mm of the edge of the steel plate (in addition to the head or tail of the steel plate) being lower than or higher than the target final cooling temperature by 50℃ or more; the local temperature unevenness refers to the final cooling temperature of the local part (in addition to the head, tail and edge of the steel plate) or longitudinal strip distribution being higher or lower than the target final cooling temperature by 50℃ or more; and the wave-shaped temperature unevenness refers to the wave-shaped temperature unevenness in the rolling direction of the steel plate, and the local final cooling temperature being higher or lower than the target final cooling temperature by 50℃ or more. By dividing the final cooling temperature unevenness type of the target steel plate into the above four categories, a one-to-one correspondence between the overall position performance of the steel plate and the final cooling temperature can be established, and the relationship between the process and the performance can be more objectively and truly reflected.

[0049] In an embodiment, the process solidification based on the final cooling temperature unevenness type of the target steel plate includes:

[0050] In the case where the target steel plate has at least one of head-tail temperature unevenness, edge temperature unevenness, and local temperature unevenness, the water flow parameters of the water cooling process are optimized for process solidification.

[0051] Exemplarily, if the target steel plate has at least one of head-tail temperature unevenness, edge temperature unevenness, and local temperature unevenness, it proves that the water cooling process has defects, i.e., the water flow is too large in some places, resulting in too low final cooling temperature after water cooling, and the water flow is too small in some places, resulting in too high final cooling temperature after water cooling. The water flow parameters of the water cooling process are optimized based on the final cooling temperature unevenness type of the target steel plate, thereby realizing the optimization of the water cooling process based on the final cooling temperature unevenness type of the target steel plate.

[0052] In an embodiment, the water flow parameters of the water cooling process include water flow position and water flow size, and the optimization of the water flow parameters of the water cooling process in the case that the target steel plate has at least one of the head-tail temperature unevenness, the edge temperature unevenness, and the local temperature unevenness includes:

[0053] In the case that the target steel plate has at least one of the head-tail temperature unevenness, the edge temperature unevenness, and the local temperature unevenness, the water flow position and the water flow size of the water cooling process are optimized.

[0054] For example, if the water cooling is excessive, the temperature is too low, and if the water cooling is insufficient, the temperature is too high.

[0055] In the case of head-tail temperature unevenness, it is proved that the water flow size of the outlet for water cooling the head and tail of the steel plate can be too large or too small, and the head-tail shielding coefficient of the water cooling process is optimized, that is, the water flow parameters of the outlet for water cooling the head and tail of the steel plate are optimized, if the head-tail temperature is too high, the water flow size of the outlet for water cooling the head and tail of the steel plate is increased; if the head-tail temperature is too low, the water flow size of the outlet for water cooling the head and tail of the steel plate is reduced.

[0056] In the case of edge temperature unevenness, it is proved that the water flow size of the outlet for water cooling the edge of the steel plate can be too large or too small, and the edge water crown control of the water cooling process is optimized, that is, the water flow parameters of the corresponding outlet for water cooling the edge of the steel plate are optimized, if the edge temperature is too high, the water flow size of the outlet for water cooling the edge of the steel plate is increased; if the edge temperature is too low, the water flow size of the outlet for water cooling the edge of the steel plate is reduced.

[0057] In the case of local temperature unevenness, it is proved that the water flow size of the outlet for water cooling the local part of the steel plate can be too large or too small, and the water flow parameters of the outlet for water cooling the local part of the steel plate are optimized, if the local temperature is too high, the water flow size of the corresponding outlet for water cooling the local part of the steel plate is increased; if the local temperature is too low, the water flow size of the corresponding outlet for water cooling the local part of the steel plate is reduced.

[0058] In an embodiment, in the case that the target steel plate has wavy temperature unevenness, it is determined that the profile of the target steel plate is uneven.

[0059] For example, the wavy temperature unevenness of the target steel plate is generally caused by poor rolling shape of thin-gauge steel plate, and thus the problem of wavy temperature distribution. Therefore, in the case that the target steel plate has wavy temperature unevenness, it can be determined that the profile of the target steel plate is uneven, and based on the overall final cooling temperature distribution, not only the water cooling process but also the profile problem of the steel plate after rolling can be monitored.

[0060] In one embodiment, when it is determined that the target steel plate profile is uneven, a straightening process is performed on the target steel plate to solidify the process.

[0061] Illustratively, when it is determined that the target steel plate profile is uneven, a straightening process is performed on the target steel plate to improve the unevenness of the steel plate profile, thereby improving the unevenness of the final cooling temperature and improving the performance of the steel plate.

[0062] Illustratively, the method adds an infrared thermal imaging system after the post-rolling water cooling equipment, obtains the final cooling temperature distribution of the entire steel plate surface after image processing, and optimizes the water cooling process based on the final cooling temperature distribution, thereby improving the uniformity of the temperature of the steel plate after water cooling, solving the problem of incomplete evaluation of the traditional final cooling temperature, and realizing directional optimization of the water cooling process for the uniformity of the final cooling temperature of the steel plate.

[0063] Further, Figure 2 A temperature diagram for evaluating the final cooling temperature of a steel plate according to a conventional method is shown, the horizontal axis represents time, and the vertical axis represents temperature. The temperature value is taken as the temperature of the middle position of the steel plate as the determination temperature of the final cooling temperature of the steel plate. The first curve on the left is the temperature of the middle position of the steel plate before water cooling, the middle curve is the temperature of the middle position of the upper surface of the steel plate after water cooling, and the curve on the right is the temperature of the middle position of the lower surface of the steel plate after water cooling. This evaluation method cannot fully represent the temperature uniformity of the entire surface of the TMCP state steel plate.

[0064] Further, Figure 3 A final cooling temperature distribution diagram of a steel plate before optimization of a water cooling process obtained by a thermal imaging device is shown, Figure 3 The left and right parts are the head and tail, the left side is the head, and the right side is the tail. The upper and lower parts are the edge parts. As shown in the figure, there is a black area in the head and tail temperature, which corresponds to a lower temperature in the thermal imaging result, and the water cooling is excessive. The middle gray area corresponds to a higher temperature in the thermal imaging result, and the water cooling is insufficient. The gray area with black horizontal distribution lines is a wavy temperature distribution, and the steel plate surface is uneven. The final cooling temperature of the post-rolling water cooled steel plate is measured by the system, and the thermal imaging diagram of the final cooling temperature of the entire surface of the steel plate is obtained. The distribution data of the final cooling temperature of the entire surface of the steel plate is obtained by using image processing software, so as to determine the overall final cooling temperature distribution of the target steel plate after water cooling.

[0065] Further, Figure 4 A final cooling temperature distribution diagram of a steel plate after optimization of a water cooling process obtained by a thermal imaging device is shown, Figure 3The optimization water cooling process before the steel plate final cooling temperature distribution obtained by the thermal imaging device is shown. After the whole process is solidified, the steel plate temperature distribution uniformity after water cooling is greatly improved.

[0066] Further, as to the above-mentioned Figure 1 To realize the method shown, the embodiment of the present application also provides a steel plate water cooling control device for realizing the above-mentioned Figure 1 The device embodiment corresponds to the foregoing method embodiment.
