It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by showing examples of the present application.
[0047] It should be noted that, in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover a non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, elements defined by the statement "comprising..." do not exclude the presence of additional identical elements in the process, method, article or device comprising the said elements.
[0048] To solve the problems of the prior art, embodiments of the present application provide a steel processing method, device, equipment and system. First, the steel processing method provided by the embodiments of the present application will be introduced below.
[0049] Figure 1 It shows a schematic flowchart of a steel processing method provided by an embodiment of the present application. The above method is applied to a steel processing system, and the above steel processing system includes an open-flame heating furnace, and the above open-flame heating furnace includes multiple temperature zones, such asFigure 1 As shown, each temperature zone includes burners for heating, and the method includes the following steps: S101 to S103.
[0050] S101: Set the first thermocouple at multiple preset positions on the test steel, and the distance between the above-mentioned preset positions is greater than the preset distance.
[0051] In specific implementation, a thermocouple is a commonly used temperature sensor that measures temperature through the potential difference at its two ends. To accurately measure the temperature at different positions on the steel surface, in this step, first select multiple positions on the steel surface for temperature testing. These positions should be evenly distributed, and the interval between them is greater than a certain preset distance to ensure that different areas of the entire steel can be covered. First, determine the test positions according to the shape of the steel and the heating requirements, and then install thermocouples at each test position. The positions of the thermocouples are usually selected in key areas on the steel surface, such as the middle, both ends, and edges, etc. Ensure that the installation of the thermocouples does not affect the heating process of the steel and has good contact to ensure accurate data.
[0052] S102: Heat the above-mentioned test steel through the above-mentioned open-flame heating furnace, and determine the heating-up curves corresponding to the above-mentioned multiple preset positions through the above-mentioned first thermocouple.
[0053] In specific implementation, start the open-flame heating furnace to heat the test steel. The open-flame heating furnace will provide open-flame heating through burners to generate different temperature zones, and use thermocouples to monitor the temperature changes at different preset positions on the steel surface in real time. According to the real-time temperature change data, generate heating-up curves. Each test position will correspond to an independent curve, reflecting the temperature change trend of that position during the heating process. Through the heating process of the heating furnace, monitor the temperature change conditions of each position, and then draw the heating-up curves of each position.
[0054] S103: Adjust the target temperatures of each temperature zone in the above-mentioned open-flame heating furnace according to the multiple above-mentioned heating-up curves.
[0055] In specific implementation, compare the heating-up curves of different preset positions to identify the phenomenon of uneven heating. For example, if some areas heat up too slowly, the temperature of the temperature zone in that area may need to be increased; conversely, if some areas heat up too quickly, the temperature of that area may need to be decreased. Thus, adjust the target temperatures of each temperature zone in the open-flame heating furnace. The heating furnace is generally divided into multiple temperature zones, and each temperature zone corresponds to a different temperature control range. According to the feedback of the heating-up curves, adjust the target temperature of each temperature zone to make the heating more uniform and accurate. By controlling the combustion intensity or flame distribution of each burner, optimize the heat distribution between each temperature zone.
[0056] S104: Process the steel through the above-mentioned open-flame heating furnace.
[0057] In a specific implementation, through the adjustment in S103, the temperature distribution of the heating furnace has reached the optimal state. Therefore, it can ensure that the temperature of the steel is uniform during the heating process. Then, in the open-flame heating furnace, the steel begins to undergo hot processing, such as forging, hot rolling, or heat treatment, etc. With precisely controlled temperature, the steel can be processed within the most suitable temperature range, avoiding quality problems caused by overheating or insufficient heating.
[0058] The steel processing method provided by the embodiment of the present application sets thermocouples at multiple preset positions of the test steel, the distance between the above-mentioned preset positions is greater than the preset distance, heats the above-mentioned test steel through the above-mentioned open-flame heating furnace, determines the heating curves corresponding to the above-mentioned multiple preset positions, adjusts the target temperature of each temperature zone in the above-mentioned open-flame heating furnace according to the multiple above-mentioned heating curves, and then processes the steel through the above-mentioned open-flame heating furnace, ensuring the uniformity of the open-flame furnace temperature, thereby realizing uniform heating of the steel plate.
[0059] In order to ensure the processing quality and production efficiency of the steel, in some embodiments, the above S104 includes: the following steps may be included: S1041 to S1042.
[0060] S1041: Set second thermocouples in each of the above temperature zones to determine the temperature changes in each of the above temperature zones during the processing.
[0061] In a specific implementation, first, according to the temperature zone division of the open-flame heating furnace, select suitable positions in each temperature zone for installing the second thermocouples. Since the heat distribution in each temperature zone is different, the selected positions are usually in areas where the temperature change is more obvious or the temperature gradient is larger. For example, install a thermocouple at the middle position of the furnace body to obtain the average temperature of this area; install thermocouples in areas near the furnace wall or the heating source to monitor the possible temperature difference. After installing the second thermocouples, the system transmits the temperature data of each temperature zone in real time through the signal connection between the temperature control system and the thermocouples, and conducts real-time temperature monitoring during the steel processing process.
[0062] S1042: Based on the above temperature changes in each of the above temperature zones, adjust the ignition duration of the burners in each of the above temperature zones.
[0063] In specific implementation, based on the temperature change data of each temperature zone obtained in S1041, the heating curves of each temperature zone are analyzed. By comparing the heating curves of each temperature zone with the set target temperature, it is determined whether the temperature difference of each temperature zone exceeds the preset error range. If there is a large deviation in temperature change, it is necessary to adjust the ignition duration of the burner. For the temperature zone with a slow temperature rise, it may be due to insufficient heat. The ignition duration of the burner can be increased to extend the heating time and increase the heat input to this area. This can gradually increase the temperature in the temperature zone to reach the target temperature. For the temperature zone with a too fast temperature rise, it may be due to excessive heat in this area. The system shortens the ignition duration of the burner, reduces the heating time, and lowers the temperature of this area. Excessive heat input is reduced to avoid local overheating on the surface of the steel.
[0064] In the above implementation manner provided by the embodiments of the present application, through the real-time monitoring and intelligent adjustment of the temperature changes in each temperature zone, it is ensured that the temperature control of each area during the steel processing is accurate, avoiding the situation of uneven temperature. By setting thermocouples in different temperature zones and adjusting the ignition duration of the burner in real time according to the temperature change, the processing quality and production efficiency of the steel are ensured.
[0065] In order to accurately monitor and adjust the temperature of each temperature zone in the open-flame heating furnace, in some implementation manners, the above S1041 may include the following steps: S10411 to S10413.
[0066] S10411: In each of the above temperature zones of the above open-flame heating furnace, a plurality of second thermocouples are arranged at equal intervals according to the furnace width.
[0067] In specific implementation, the width of the furnace chamber usually refers to the horizontal scale of the heating furnace, that is, the horizontal dimension of the furnace body. Furnaces with different widths will affect the heat distribution, so it is necessary to reasonably arrange the thermocouples according to the width. After calculating the width of the furnace chamber, according to the number of thermocouples to be arranged, they are arranged at equal intervals. For example, if the width of the furnace chamber is 5 meters and 5 thermocouples need to be arranged, the distance between each thermocouple is 1 meter. The installation positions of these thermocouples are usually selected in different areas of the furnace chamber, especially those parts where large temperature changes may occur, such as near the furnace wall or the flame injection area.
[0068] S10412: Set the second thermocouple according to the furnace height.
[0069] In specific implementation, the furnace height refers to the vertical dimension of the heating furnace, which directly affects the temperature distribution inside the heating furnace. Especially during the heating process, the rise of hot air flow and temperature changes often vary with height. In each temperature zone, the installation position of the second thermocouple is selected according to the furnace height.
[0070] S10413: Determine the temperature changes in each of the above temperature zones during the processing through each of the above second thermocouples.
[0071] In a specific implementation, the second thermocouples installed at different positions will collect the temperature data of each area in the furnace in real time. Each thermocouple will output a temperature value according to the temperature change at its location. Based on the real-time monitored temperature change data, determine the temperature changes in each of the above temperature zones during the processing, and judge whether it is necessary to adjust the heating process. For example, if the temperature of a certain temperature zone is too low, the ignition duration of the burner may be increased to increase the heat in that area; while for the area with too high temperature, the system may shorten the ignition duration of the burner to reduce the heat input.
[0072] The above implementation provided by the embodiments of the present application can achieve precise monitoring and adjustment of the temperatures of each temperature zone in the open-flame heating furnace by arranging the thermocouples at equal intervals, arranging the thermocouples according to the furnace height, and tracking the temperature changes in real time through these thermocouples.
[0073] In order to improve the processing quality of steel, in some embodiments, the above S1042 may include the following steps: S10421 to S10422.
[0074] S10421: Based on the above temperature changes in each of the above temperature zones, determine the temperature zones with temperatures lower than the set value.
[0075] In a specific implementation, the system has monitored the real-time temperature data of each temperature zone through the second thermocouples. These data are continuously updated during the entire heating process and transmitted to the control system. After receiving these temperature data, start comparing and analyzing the temperature values of different temperature zones. Compare the real-time temperature data with the preset target temperature, and the target temperature is determined according to the processing requirements of the steel. For example, different materials require different heating temperatures. By comparing with the target temperature, identify which temperature zones have temperatures lower than the set value.
[0076] S10422: Extend the ignition duration of the burner in the temperature zones with temperatures lower than the set value.
[0077] In a specific implementation, according to the temperature zones with temperatures lower than the set value identified in S10421, calculate the ignition duration of the burner that needs to be extended. After extending the ignition duration of the burner, the control system continuously monitors the temperature changes in the temperature zone. The system will judge whether the extended ignition duration is effective according to the real-time feedback data, that is, whether the temperature is gradually approaching the target value.
[0078] The above - mentioned implementation provided by the embodiments of the present application accurately identifies the temperature zones where the temperature is lower than the set value and extends the ignition duration of the burners in these areas, ensuring precise and uniform temperature control during the steel heating process. This method effectively avoids the problem of uneven heating, thereby improving the processing quality of the steel.
[0079] In order to ensure more efficient and stable heat transfer during the heating process, in some embodiments, the above - mentioned open - flame heating furnace further includes a plurality of circulating fans located at the top, which can be referred to Figure 2 , and the above - mentioned method may further include the following steps: S201 to S202.
[0080] S201: Set the rotation speeds of the above - mentioned plurality of circulating fans uniformly according to a preset rotation speed.
[0081] In a specific implementation, during the operation of the entire heating furnace, in order to ensure the stability of the air flow in the furnace, the control system first sets a unified "preset rotation speed" according to the temperature requirements in the furnace, the characteristics of the heating object, and the requirements of the processing process. Once the preset rotation speed is determined, the system adjusts the rotation speeds of the plurality of circulating fans uniformly through a motor drive device. These fans may be distributed in different areas of the furnace. By driving the system to adjust multiple fans simultaneously, the rotation speeds of all fans are made consistent. By adjusting the rotation speeds of multiple fans, the system can ensure the stable operation of the air flow in the furnace and maintain the air flow circulation pattern. The stability of the air flow helps to evenly distribute heat, avoid local overheating or over - cooling, and further improve the heating efficiency and the consistency of the temperature in the furnace.
[0082] S202: Set adjacent circulating fans to rotate in opposite directions to form a stable eddy current from the furnace head to the furnace tail.
[0083] In a specific implementation, in the layout of the plurality of circulating fans, adjacent fans are configured as a pair of combinations rotating in opposite directions. The rotation directions of each pair of fans are opposite, ensuring that the air flow circulates between the fans and generates an eddy - current effect. Once the fans are set to rotate in opposite directions, a stable eddy current will be formed in the furnace. The formation of the eddy current helps to promote the full mixing of the air in the furnace, enabling the heated air flow to convect between various areas in the furnace, thereby taking away heat and evenly distributing it to the surface of the steel.
[0084] Through the implementation of steps S201 and S202 in the above - mentioned implementation provided by the embodiments of the present application, the air - flow control in the heating furnace realizes refined management. S201 ensures the consistency of the air flow by setting a unified fan rotation speed, while S202 forms a stable eddy current by setting adjacent fans to rotate in opposite directions, further promoting the uniform distribution of heat in the furnace and the heating efficiency. The whole process not only improves the uniformity of the temperature distribution but also optimizes the air - flow circulation in the furnace, ensuring more efficient and stable heat transfer during the heating process.
[0085] In some embodiments, to ensure the uniformity of steel heating and the stability of the process, the above S102 includes the following steps: S1021 to S1022.
[0086] S1021: Start the above open-flame heating furnace and operate it according to the initial process parameters, and uniformly feed the test steel into the furnace chamber.
[0087] In a specific implementation, first start the open-flame heating furnace. Next, uniformly and steadily feed the test steel to be heated into the furnace chamber.
[0088] S1022: Collect the temperature data of each thermocouple and record the corresponding heating-up curve.
[0089] In a specific implementation, install multiple thermocouples at different positions in the furnace. These sensors will monitor the temperature conditions in each area of the furnace in real time. Generally, the thermocouples will be distributed at multiple key positions such as the furnace head, furnace tail, and the middle of the furnace body to ensure that the temperature distribution in the furnace can be comprehensively reflected. During the test, the temperature data of each thermocouple will be collected regularly or in real time. After the temperature data is collected, record the corresponding heating-up curve.
[0090] In the above embodiments provided by the embodiments of the present application, steps S1021 and S1022 are key operations in the entire heating process. Step S1021 ensures the stability of the temperature in the furnace and can uniformly heat the fed steel by precisely starting the heating furnace and controlling the process parameters. Step S1022, by arranging multiple thermocouples and collecting temperature data, records the heating-up curve in real time, thereby ensuring the monitoring and optimization of the heating process. Through these two steps, the temperature change in the furnace can be effectively controlled, and the uniformity of steel heating and the stability of the process can be guaranteed.
[0091] To optimize the heating process, in some embodiments, referring to Figure 3 , the above S103 may include performing the following steps for each temperature zone: S301 to S303.
[0092] S301: Obtain the heating-up curve corresponding to the temperature zone.
[0093] In a specific implementation, divide the temperature in the furnace into multiple temperature zones. To obtain the heating-up data of each temperature zone, appropriate thermocouples must be arranged in these temperature zones. Through real-time data collection by the thermocouples, obtain the heating-up curve corresponding to the temperature zone.
[0094] S302: When the temperature in the above heating-up curve is lower than the expectation, increase the target temperature of this temperature zone.
[0095] In specific implementation, compare with the preset target temperature. If the temperature of a certain temperature zone shown by the heating curve is lower than the expected target, it is determined that there is a problem of insufficient heating in this temperature zone. When it is found that the temperature is lower than expected, the control system will automatically increase the target temperature of this temperature zone. This can be achieved by increasing the fuel supply, increasing the air flow rate, adjusting the atmosphere in the furnace, etc.
[0096] S303: When the temperature of the above heating curve is higher than expected, lower the target temperature of this temperature zone.
[0097] In specific implementation, if the temperature of a certain temperature zone shown by the heating curve is higher than the expected target, temperature correction needs to be carried out for this temperature zone. Excessive temperature may cause the steel to overheat, and even affect the quality or heating uniformity of the steel. At this time, lower the target temperature of this temperature zone.
[0098] The above implementation manner provided by the embodiments of the present application realizes the precise adjustment of the temperature of the temperature zones in the furnace through a meticulous control system. First, obtain the heating curve through S301 to monitor the temperature status of each temperature zone in real time. Then, S302 and S303 automatically adjust the target temperature according to the temperature deviation to ensure that the heating process of the temperature zone meets the expectations. If the temperature is lower than expected, the system will accelerate heating by increasing the target temperature; if the temperature is higher than expected, it will avoid overheating by lowering the target temperature. These adjustments can not only ensure the heating uniformity of the steel, thus optimizing the heating process.
[0099] In an embodiment of the present application, first conduct black box tests for different steel grades to obtain the actual heating curve of the steel plate. Set the gradient heating system according to the heating curve from the furnace head to the tail of the furnace to make the heating rate of each part of the steel plate uniform; place the thermocouples in the furnace staggeredly, and place them at the 1 / 4 and 1 / 3 positions away from the furnace hearth respectively to increase the uniformity of the temperature measurement point distribution; adopt the automatic pulse control mode of the burners, and the burners in the same temperature zone cycle ignition and shutdown; the two adjacent circulating fans at the furnace top operate in opposite directions, so as to form a continuous and stable air flow from the furnace head to the tail.
[0100] Specifically, bury the thermocouple wire of the black box device into the steel plate of the specified product specification, send it into the furnace for heating according to the temperature system in the regulations, export the black box data after the steel plate is taken out of the furnace, and obtain the actual heating curve of the steel plate; set different target temperatures for different zones according to the process temperature system of this steel grade and the black box test data; confirm that all burners are turned on automatically and turn on the pulse automatic control mode; turn on the circulating fans at the furnace top, between 40Hz, and adopt the reverse operation mode of adjacent fans.
[0101] Conduct a comparative test using the existing technology method and the method of the present application. Table 1 is the data comparison table of the impact energy in the plate width direction before and after using the method of the present invention. It can be seen from Table 1 that the uniformity of the impact energy of the same steel grade is significantly improved after using the present invention.
