Description

Technical Field

[0001] This application relates to the field of online inspection technology for hot-rolled steel plates in the metallurgical industry, and particularly to optical width measuring equipment, cooling control methods, and storage media. Background Technology

[0002] In the production process of hot-rolled steel plates, in order to obtain the width data of the steel plates in real time, a grating width measuring instrument is usually installed above the roller conveyor to measure the width of the steel plates running on the roller conveyor.

[0003] Because the high-temperature steel plate continuously radiates heat, the grating width measuring instrument located above the roller conveyor needs to continuously withstand the heat radiation from the high-temperature steel plate below. In order to maintain the measurement accuracy and service life of the grating assembly, the relevant technology adopts a forced cooling method, such as using a cooling pipe that runs through the entire width of the roller conveyor, with air outlets of the same diameter evenly opened along its entire length, and using a compressed air system to uniformly cool the entire grating assembly.

[0004] However, in specific operating conditions where the steel plate is fixed against one side of the roller conveyor (such as the right or left side), if the above-mentioned traditional uniform jetting method is used, most of the cooling gas will be wasted ineffectively, reducing energy efficiency and increasing costs. Summary of the Invention

[0005] This application provides an optical width measurement device, a cooling control method, and a storage medium, aiming to solve the problem that the traditional method of uniformly cooling the entire grating assembly results in the ineffective consumption of most of the cooling gas, reduced energy utilization, and increased costs.

[0006] In a first aspect, embodiments of this application provide an optical width measuring device for measuring steel plates, the optical width measuring device comprising:

[0007] frame;

[0008] A roller conveyor is located below the frame, and the roller conveyor has steel plates arranged opposite each other on a near side and a far side along its width direction; and the width direction of the roller conveyor is consistent with the length direction of the frame.

[0009] Multiple grating assemblies are mounted on the frame and arranged sequentially along the length of the frame;

[0010] A cooling assembly is disposed on the frame, the air outlet direction of the cooling assembly is towards the grating assembly, and cool air is delivered to the grating assembly;

[0011] The cooling component delivers more cold air to the side of the steel plate closer to the plate than to the side of the steel plate farther away.

[0012] A further technical solution is that the cooling assembly includes a cooling pipe, a control valve, and an air supply component. The cooling pipe is fixed to the frame, the air inlet of the cooling pipe is connected to the air supply component through the control valve, and the air outlet of the cooling pipe is oriented towards the grating assembly.

[0013] A further technical solution is that the cooling pipe includes a first pipe section and a second pipe section connected to each other. The first pipe section and the second pipe section are arranged sequentially along the length of the cooling pipe. The first pipe section is arranged opposite to the side of the steel plate that is close to it, and the second pipe section is arranged opposite to the side of the steel plate that is far away from it. The amount of cold air delivered by the first pipe section is greater than the amount of cold air delivered by the second pipe section.

[0014] A further technical solution is that the first pipe section is provided with a first air outlet, the second pipe section is provided with a second air outlet, and the number and / or diameter of the first air outlet is larger than that of the second air outlet.

[0015] A further technical solution is that the first air outlet and the second air outlet are distributed at equal intervals along the length of the cooling pipe.

[0016] A further technical solution is that the optical width measurement device also includes a connector, and the cooling pipe is fixed to the frame through the connector.

[0017] A further technical solution is that the optical width measuring device also includes a temperature sensor, which is installed at a preset position on the frame, wherein the preset position is on the same side as the side of the steel plate closest to it.

[0018] Secondly, embodiments of this application also provide a cooling control method for an optical width measuring device, applied to the aforementioned optical width measuring device. The main controller of the optical width measuring device is used to execute the steps of the cooling control method, which includes:

[0019] Obtain the temperature detected by the temperature sensor;

[0020] Determine whether the detected temperature is greater than the first preset temperature;

[0021] If the detected temperature is greater than the first preset temperature, the solenoid valve is opened to start the cooling process.

[0022] A further technical solution is that determining whether the detected temperature is greater than the first preset temperature also includes:

[0023] If the detected temperature is not greater than the first preset temperature, then determine whether the detected temperature is less than the second preset temperature;

[0024] If the detected temperature is less than the second preset temperature, the solenoid valve is closed, wherein the first preset temperature is greater than the second preset temperature.

[0025] Thirdly, embodiments of this application also provide a computer-readable storage medium storing a computer program that, when executed by a processor, can implement the above-described method.

[0026] This application provides an optical width measurement device, a cooling control method, and a storage medium. The optical width measurement device includes: a frame; a roller conveyor located below the frame, the roller conveyor having a steel plate proximal to and a steel plate distal to the frame along its width direction; the width direction of the roller conveyor is consistent with the length direction of the frame; multiple grating assemblies mounted on the frame and arranged sequentially along the length direction of the frame; and a cooling assembly disposed on the frame, the cooling assembly's air outlet direction facing the grating assemblies, and delivering cold air to the grating assemblies; wherein the amount of cold air delivered by the cooling assembly to the steel plate proximal to the frame is greater than the amount of cold air delivered to the steel plate distal to the frame.

[0027] This embodiment of the application sets the cooling component to have asymmetrical cold air delivery rates on the side of the steel plate closer to it and the side farther from it. Specifically, the cold air delivery rate on the side closer to the steel plate is greater than that on the side farther from it. In actual hot rolling production lines, the steel plate runs stably along one side of the roller conveyor for extended periods, resulting in heat radiation being concentrated primarily on the side closer to the steel plate on the roller conveyor, while the other side (the side farther from the steel plate) is under low heat load. Therefore, by increasing the cold air delivery rate on the side closer to the steel plate, the cooling intensity on the side closer to the steel plate can be enhanced, while the cooling output on the side farther from the steel plate can be appropriately reduced. This significantly reduces ineffective air consumption while ensuring that the overall temperature of the grating assembly remains within a safe operating range, thus solving the energy waste problem of traditional uniform cooling methods under specific operating conditions.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0045] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0046] As used in this specification and the appended claims, the term "if" may be interpreted, depending on the context, as "when," "once," "in response to determination," or "in response to detection." Similarly, the phrases "if determined" or "if [described condition or event] is detected" may be interpreted, depending on the context, as "once determined," "in response to determination," "once [described condition or event] is detected," or "in response to detection of [described condition or event]."

[0047] To address the aforementioned issues, this application provides an optical width measurement device, a cooling control method, and a storage medium that can enhance the cooling intensity on the side of the steel plate closest to the plate while appropriately reducing the cooling output on the side furthest from the plate, thereby reducing ineffective gas consumption and improving energy efficiency.

[0048] See Figures 1-4 The optical width measuring device provided in this application is used to measure steel plates, including a frame 10, a roller conveyor, a cooling assembly, and multiple grating assemblies.

[0049] The roller conveyor is located below the frame 10, and the roller conveyor has a steel plate on a near side and a steel plate on a far side arranged opposite each other along its width direction; and the width direction of the roller conveyor is consistent with the length direction of the frame 10, for example, the width direction of the roller conveyor is parallel or approximately parallel to the length direction of the frame 10.

[0050] Multiple grating assemblies are mounted on the frame 10 and arranged sequentially along the length of the frame 10 for detecting the width of the steel plate.

[0051] The cooling component is disposed on the frame 10, the air outlet direction of the cooling component is towards the grating component, and the cooling component delivers cold air to the grating component. The amount of cold air delivered by the cooling component to the side near the steel plate is greater than the amount of cold air delivered to the side far from the steel plate.

[0052] The optical width measuring device provided in this embodiment sets the cooling component to have asymmetrical cold air delivery rates on the side closer to the steel plate and the side farther from the steel plate. That is, the cold air delivery rate on the side closer to the steel plate is greater than that on the side farther from the steel plate. In actual hot rolling production lines, the steel plate runs stably along one side of the roller conveyor for a long time, resulting in heat radiation mainly concentrated on the side closer to the steel plate on the roller conveyor, while the other side (i.e., the side farther from the steel plate) is under a low heat load. Based on this, by making the cold air delivery rate on the side closer to the steel plate greater than that on the side farther from the steel plate, the cooling intensity on the side closer to the steel plate can be enhanced, while the cooling output on the side farther from the steel plate can be appropriately reduced. Thus, while ensuring that the overall temperature of the grating component is within a safe operating range, ineffective air consumption is significantly reduced, solving the energy waste problem of traditional uniform cooling methods under certain operating conditions.

[0053] In some possible implementations, the grating assembly may include a grating 21 and a grating connecting plate 22, the grating connecting plate 22 being used to connect two gratings 21.

[0054] In other embodiments, a grating protection plate 23 and a grating cover plate 24 may be provided to protect the grating assembly.

[0055] In some possible implementations, the grating assembly may include a grating 21 and a grating connecting plate 22, wherein the grating 21 is used to detect the width of the steel plate; and the grating connecting plate 22 is used to connect two or more gratings 21.

[0056] In addition, in other embodiments, a grating protection plate 23 and a grating cover plate 24 may be provided to enhance the protective performance of the grating assembly. For example, the grating protection plate 23 can prevent damage from external collisions or foreign objects; the grating cover plate 24 can improve the protection level and also help with dust and water resistance.

[0057] In some possible implementations, the cooling assembly includes a cooling pipe 30, a control valve, and an air supply component. The cooling pipe 30 is fixed to the frame 10, the air inlet of the cooling pipe 30 is connected to the air supply component through the control valve, and the air outlet of the cooling pipe 30 is oriented toward the grating assembly.

[0058] The control valve can be a solenoid valve, such as a two-position two-normally closed solenoid valve. This solenoid valve is electrically connected to the main controller (Programmable Logic Controller, PLC), which controls its opening or closing according to preset logic, thereby realizing the start and stop management of the cooling process.

[0059] For example, when the main controller controls the solenoid valve to open, the compressed gas supplied by the gas supply component enters the cooling pipe 30 through the control valve and is sprayed onto the grating assembly by the cooling pipe 30 to start cooling; when the main controller controls the solenoid valve to close, the gas supply passage is cut off, the compressed gas supplied by the gas supply component stops being delivered to the cooling pipe 30, the cooling pipe 30 stops delivering cold air, and the cooling process is terminated.

[0060] Thus, the use of solenoid valve control results in a simple structure and reliable response. It can effectively avoid ineffective air supply when there is no steel plate passing through, significantly improving energy utilization efficiency. Furthermore, the cooling pipe 30 has only one controlled air inlet point, which is directly connected to the solenoid valve. This eliminates the need for complex branch pipes and multiple control components, simplifying the air circuit layout, reducing processing difficulty and system cost, and improving sealing reliability.

[0061] In some possible implementations, the cooling assembly may further include a gas processing unit (often referred to as a "tri-unit") disposed in the gas path between the gas supply unit and the control valve, for pre-treating the compressed gas from the gas supply unit to improve gas cleanliness, stability and applicability.

[0062] For example, the triplet may sequentially include a filter, a pressure reducing valve, and an oil mist lubricator, with compressed gas flowing through these three components in sequence along the airflow direction:

[0063] The filter is used to remove moisture, oil, dust and other solid particulate impurities from compressed gas and prevent the tiny air outlets (such as holes with a diameter of 0.8 mm or 1.2 mm) from becoming clogged.

[0064] The pressure reducing valve is used to regulate the input high-pressure compressed air to the stable operating pressure required by the equipment (e.g., 0.4–0.6 MPa), ensuring that the flow distribution of each air outlet of the cooling pipe 30 meets the design expectations;

[0065] Oil mist lubricators are used to inject a small amount of atomized lubricating oil into clean, regulated compressed air to lubricate downstream pneumatic components (such as solenoid valves) and extend their service life.

[0066] Through the synergistic effect of the above three components, the quality of compressed gas entering the cooling pipe 30 can be significantly improved, ensuring the long-term reliable operation of the cooling system, which is especially suitable for optical detection environments with high requirements for gas source cleanliness and stability.

[0067] In some embodiments, the cooling pipe 30 is arranged along the entire length of the frame 10, and its extension range matches the distribution area of ​​the grating components, thereby effectively covering all grating components and achieving a stable and reliable cooling function.

[0068] In some possible implementations, the cooling pipe 30 includes a first pipe section and a second pipe section connected to each other. The first pipe section and the second pipe section are arranged sequentially along the length of the cooling pipe 30. The first pipe section is arranged opposite to the side of the steel plate that is close to it, and the second pipe section is arranged opposite to the side of the steel plate that is far away from it. The amount of cold air delivered by the first pipe section is greater than the amount of cold air delivered by the second pipe section.

[0069] By dividing the cooling pipe into a first pipe section and a second pipe section, with the first pipe section corresponding to the side closer to the steel plate and the air output of the first pipe section being greater than that of the second pipe section, more cold air can be sprayed onto the grating assembly area on the side closer to the steel plate, enhancing the cooling intensity on the side closer to the steel plate, while a small amount of cold air is sprayed onto the grating assembly on the other side (i.e., the side farther from the steel plate), appropriately reducing the cooling output on the side farther from the steel plate, reducing ineffective air consumption, and solving the energy waste problem of traditional uniform cooling methods under specific operating conditions.

[0070] See Figure 4 In some possible implementations, the first pipe segment is provided with a first vent 31, the second pipe segment is provided with a second vent 32, and the number and / or diameter of the first vent 31 is greater than that of the second vent 32.

[0071] For example, in some possible implementations, the number of first vents 31 is greater than the number of second vents 32.

[0072] For example, in some possible implementations, the diameter of the first vent 31 is larger than the diameter of the second vent 32.

[0073] For example, in some possible implementations, the diameter of the first vent 31 is larger than the diameter of the second vent 32, and the number of first vents 31 is greater than the number of second vents 32.

[0074] One approach is to utilize fluid dynamics principles to adjust flow resistance by changing the orifice diameter, thereby achieving passive flow distribution. For example, taking a cooling pipe 30 with an inner diameter of 13mm, an outer diameter of 15mm, and a total of 56 orifices, and a steel plate running on the right side of the roller conveyor, if approximately 80% of the cooling air needs to be automatically concentrated on the right side of the roller conveyor (i.e., an airflow distribution ratio of 4 (right side):1 (left side), the number of the first and second air outlets 31 can be allocated according to a preset area length ratio. For instance, if the first pipe section occupies 2 / 3 of the length of the cooling pipe 30, and the second pipe section occupies 1 / 3 of the length of the cooling pipe 30, then the calculated number of the first air outlet 31 is approximately 37, and the number of the second air outlet 32 ​​is approximately 19.

[0075] Then, based on the airflow distribution ratio of 4:1, the aperture ratio between the first air outlet 31 and the second air outlet 32 ​​can be calculated to be approximately 1.43. Based on this, the first air outlet 31 can be selected with a standard aperture of Φ1.2mm, and the second air outlet 32 ​​can be selected with a standard aperture of Φ0.8mm.

[0076] When compressed air reaches the critical flow state in the cooling pipe 30, the flow rate Q through each outlet is proportional to the flow area A of the outlet.

[0077] Based on the above, the diameter Φ of the first vent is 1.2mm, the diameter Φ of the second vent is 0.8mm, the number of first vents is approximately 37, and the number of second vents is approximately 19. The relevant calculation process is as follows:

[0078] Area of ​​the first vent: A1=π*(1.2 / 2)2=1.13mm2;

[0079] Area of ​​the second vent: A2=π*(0.8 / 2)2=0.50mm2;

[0080] Total area of ​​all first vent holes: A1 总 =37 * 1.13 ≈ 41.81 mm²;

[0081] Total area of ​​all second vents: A2 总 =19 * 0.50 ≈ 9.50 mm²;

[0082] Total air outlet area: A 总 =41.81 + 9.50 = 51.31 mm²;

[0083] The flow rate percentage of the first pipe section: A_total_right / A_total = 41.81 / 51.31 ≈ 81.5%;

[0084] The flow rate percentage of the second pipe section is: A_total_left / A_total = 9.50 / 51.31 ≈ 18.5%.

[0085] The calculation results show that with a diameter Φ of 1.2 mm for the first air outlet and Φ of 0.8 mm for the second air outlet, the number of first air outlets is approximately 37 and the number of second air outlets is approximately 19. This allows more than 81% of the cooling air to be automatically guided to the high-temperature zone on the right side (i.e., the side closer to the steel plate), realizing the energy-saving design concept of "heavy heat and heavy cooling, light heat and light cooling" and reducing the waste of resources.

[0086] In addition, it should be noted that the specific number and diameter of the first and second air outlets can be set according to the actual required airflow distribution ratio, and this application does not limit this.

[0087] In other embodiments, the asymmetric cooling effect of this application can be verified by computational fluid dynamics (CFD) simulation. Taking the side of the steel plate closer to the right as an example, the specific steps are as follows:

[0088] 1. Software platform: SolidWorks and CATIA, industry-standard 3D CAD software, are used for geometry creation.

[0089] Model Strategy: Establish an internal fluid domain model for the cooling pipe, such as a tubular cavity with an outer diameter of 15mm and an inner diameter of 13mm, whose wall is a thickness-free curved surface. On the lower wall of the pipe, create 56 vent holes as described in the above embodiment. Specifically, 37 holes with a diameter of 1.2mm are distributed in the right-hand area; 19 holes with a diameter of 0.8mm are distributed in the left-hand area, with all holes spaced at a consistent distance.

[0090] External flow domain: To simulate the free development of the airflow after it is ejected, a sufficiently large cuboid air domain is established below all the air outlets to ensure that the exit boundary does not impose unreasonable constraints on the jet.

[0091] 2. Mesh Generation and Optimization:

[0092] Mesh type: An unstructured hybrid mesh with a hexahedron core is used. For complex orifice areas, a "cut volume" mesh technique is used for local refinement to ensure that the geometry of the orifice is accurately captured.

[0093] Mesh refinement was performed inside and near all vents. Boundary layer meshes were generated on the inner wall of the pipe and the walls of the vents. The thickness of the first mesh layer was precisely calculated to ensure that the dimensionless wall distance y+ value was within a reasonable range of 30 to 300 to accommodate the subsequently selected turbulence model.

[0094] Mesh Independence Verification: To ensure the simulation results are independent of the number of meshes, a mesh independence test was performed. Three mesh schemes (approximately 2 million, 5 million, and 10 million meshes respectively) were used sequentially for calculations, monitoring the percentage of total mass flow in the right-hand region relative to the total outlet flow. When the mesh count increased from 5 million to 10 million, the change in the right-hand flow percentage was less than 0.5%. Therefore, a model with approximately 5 million meshes was selected for formal calculations.

[0095] 3. Boundary conditions and solver settings:

[0096] Physical model: Since compressed air may reach the speed of sound at the orifice, a gas compressible flow model is chosen.

[0097] The industry-standard Realizable k-epsilon turbulence model was selected, with enhanced wall treatment enabled. This model can accurately predict the flow separation in circular orifice jets and pipes.

[0098] Boundary conditions:

[0099] 1) Inlet: Set to pressure inlet. Total pressure is set to 0.5 MPa (gauge pressure), and static temperature is set to 25℃. This setting is consistent with the actual gas source conditions.

[0100] 2) Outlet: All external surfaces of the external air zone are set as pressure outlets with a gauge pressure of 0 Pa (i.e., ambient atmospheric pressure).

[0101] 3) Walls: All pipe inner walls and external air zone boundaries are set as non-slip thermal insulation walls.

[0102] Solving for control:

[0103] Use a pressure-based coupled solver.

[0104] The discrete scheme uses a second-order upwind approach to achieve higher accuracy.

[0105] The calculations continued until all residual monitoring curves decreased by at least three orders of magnitude (to 10). -4 (The following), and when the export quality flow monitoring value remains stable, it is determined to be converged.

[0106] 4. Post-processing and result analysis: After the simulation converges, the results are quantitatively and qualitatively analyzed by the post-processor.

[0107] 4.1 Quantitative Analysis - Flow Distribution:

[0108] In post-processing, two "surface groups" were created: one containing all 37 right-side vents (1.2 mm) and the other containing all 19 left-side vents (0.8 mm). The total mass flow rate through these two face groups was calculated using the software's area integration function.

[0109] Right-side region mass flow rate: m 右 =0.07178 kg / s;

[0110] Mass flow rate in the left region: m 左 =0.01793 kg / s;

[0111] Total mass flow rate: m 总 =0.0896 kg / s;

[0112] Right-side traffic percentage: (m 右 / m 总 ) * 100% ≈ 80%;

[0113] The quantitative result is in high agreement with the theoretical calculation of 81.5%, and the error is within the engineering acceptable range.

[0114] See Figure 5 , Figure 5 This is a simulation diagram of the static pressure distribution in the cross-section of the cooling pipe generated by computational fluid dynamics (CFD) in this application (i.e., flow field visualization - static pressure cloud map of the pipe cross-section). The cloud map shows that the static pressure distribution inside the cooling pipe is not completely uniform. In the right region near the inlet, the static pressure is slightly lower. This is because the flow resistance is smaller and the flow split is larger on the right side. Figure 4 This can intuitively explain the driving force behind the automatic rightward tilt of traffic.

[0115] See Figure 6 , Figure 6 This is a simulation diagram of the velocity distribution at the outlet holes in this application, including velocity contour maps and streamline diagrams, used to visually demonstrate the velocity distribution and flow path of the gas as it passes through the outlet holes. Rendering the airflow velocity at the outlet surfaces of all outlet holes clearly shows that the 1.2mm orifice area on the right is represented by red or yellow, indicating high speed, while the 0.8mm orifice area on the left is mainly represented by blue or green, indicating low speed.

[0116] The streamlines ejected from the exhaust port also show that the core velocity of the jet on the right side is significantly higher than that on the left. This directly proves that the cooling intensity (the convective heat transfer coefficient is strongly correlated with the flow velocity) in the right region is much higher than that on the left.

[0117] Thus, the simulation results clearly confirm that precise flow distribution can be achieved by simply changing the aperture of the air outlets on the left and right sides, such as automatically guiding more than 80% of the cooling gas to the target area on the right.

[0118] In some possible implementations, the first vent and the second vent are distributed at equal intervals along the length of the cooling pipe.

[0119] In some possible implementations, the optical width measurement device further includes a connector through which the cooling pipe is fixed to the frame.

[0120] The connector can be a stainless steel pipe clamp. For example, the cooling pipe can be fixed in the upper groove of the frame by the stainless steel pipe clamp.

[0121] In some possible implementations, the optical width measuring device further includes a temperature sensor mounted at a preset position on the frame, wherein the preset position is on the same side as the side of the steel plate closest to it.

[0122] The preset position can be the grating housing in the high-temperature zone, or the center position on one side of the frame.

[0123] For example, if the side of the steel plate closest to the right is the right side, the preset position could be the grating housing in the high-temperature zone on the right side, or the center position on the right side of the frame.

[0124] Based on the optical width measuring device provided in the above embodiments, this application also provides a cooling control method for the optical width measuring device, see reference. Figure 7 , Figure 7 This is a flowchart illustrating a first embodiment of a cooling control method for an optical width measuring device provided in this application. The main controller of the optical width measuring device is used to execute the steps of the cooling control method, which includes the following steps:

[0125] Step 110: Obtain the detected temperature from the temperature sensor.

[0126] Step 120: Determine whether the detected temperature is greater than the first preset temperature.

[0127] Step 130: If the detected temperature is greater than the first preset temperature, then open the solenoid valve and start the cooling process.

[0128] In some possible implementations, determining whether the detected temperature is greater than a first preset temperature further includes:

[0129] Step 140: If the detected temperature is not greater than the first preset temperature, then determine whether the detected temperature is less than the second preset temperature.

[0130] Step 150: If the detected temperature is less than the second preset temperature, then close the solenoid valve, wherein the first preset temperature is greater than the second preset temperature.

[0131] The first preset temperature can be 44℃, 45℃ or 46℃, etc., and the second preset temperature can be 34℃, 35℃ or 36℃, etc. The specific values ​​can be set and adjusted according to the actual situation.

[0132] For steps 110-150, assuming the side of the steel plate closer to the right is the right side, when the device is powered on, the solenoid valve is in the closed state and the system is in standby. The main controller continuously reads the temperature detected by the temperature sensor. When the detected temperature is greater than the first preset temperature (e.g., 45°C), it is determined that the steel plate is continuously heating the grating assembly on the right side, and immediately outputs a signal to open the solenoid valve.

[0133] When the detected temperature is lower than the second preset temperature (e.g., 35°C), it is determined that the steel plate has been removed or the heat source has disappeared. The solenoid valve is immediately closed, all cooling is stopped, and the cycle is awaited.

[0134] The above process is repeated, which can achieve an energy-saving operation mode of "strong cooling when steel is available, and cooling stopping when steel is unavailable".

[0135] By using air outlets of different diameters and numbers on the left and right sides of the cooling pipe, an inherent flow distribution bias is formed; therefore, only a single solenoid valve needs to be controlled to automatically direct the main amount of cooling air to the grating area that needs the most cooling (such as the right side), without the need for additional adjustment mechanisms or manual operation, making it easy to operate and highly reliable.

[0136] In addition, for cases where the steel plate is on the left side, simply assemble the cooling pipes in the reverse direction along the frame and change the direction of the air path to direct the main cooling air volume to the left grating assembly that needs the most cooling. This eliminates the need to replace parts or modify the design, making it easy to adapt to different production line layouts on site.

[0137] Thus, by setting the cooling components to have asymmetrical cold air delivery rates on the side closer to the steel plate and the side farther from the steel plate—that is, the cold air delivery rate on the side closer to the steel plate is greater than that on the side farther from the steel plate—the heat radiation is mainly concentrated on the side closer to the steel plate on the roller conveyor, while the other side (i.e., the side farther from the steel plate) is under a low heat load. Based on this, by increasing the cold air delivery rate on the side closer to the steel plate, the cooling intensity on the side closer to the steel plate can be enhanced, while the cooling output on the side farther from the steel plate can be appropriately reduced. This significantly reduces ineffective air consumption while ensuring that the overall temperature of the grating assembly remains within a safe operating range, thus solving the energy waste problem of traditional uniform cooling methods under specific operating conditions.
