It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification.

In the absence of more restrictions, the elements limited by the statement "comprise one..." do not exclude the existence of other identical elements in the process, method, article or equipment including the elements. The term "more than two" includes two or more than two situations.

[0024] At present, most of the existing technologies solve the problem of large amount of emulsion residue in the finished product during metal processing by adding hardware equipment, such as air knives, wiping equipment, etc. However, the above methods are costly, involve linkage control between equipment, and the control steps are relatively complicated. The effect of reducing emulsion residue is poor, which affects the quality of the finished product.

[0025] In view of this, the embodiments of the present application provide an emulsion flow control method and related equipment, which can improve the control accuracy of the emulsion flow without adding large-scale hardware equipment, reduce emulsion residue, improve the quality of finished products, avoid linkage control between equipment, streamline control steps, and improve control efficiency.

[0026] According to a first aspect of an embodiment of the present application, the present application proposes a method for regulating emulsion flow. Figure 1 A schematic diagram of a flow chart of an emulsion flow control method provided in an embodiment of the present application. Figure 1 As shown, the emulsion flow control method may include the following steps:

[0027] Step S110, obtaining emulsion target flow information, wherein the emulsion target flow information is determined based on the emulsion preset flow information and the emulsion flow correction information.

[0028] Exemplarily, the preset emulsion flow rate information can be determined according to production parameters. In some examples, the production parameters can include: rolled product material information, processing equipment operation parameter information, emulsion property information, ambient temperature information, pipeline characteristic information, etc.

[0029] In some examples, the above-mentioned rolled product material information includes: stainless steel material, alloy steel material, silicon steel material, alloy material, etc.

[0030] The above-mentioned processing equipment operation parameter information may include: rolling force information, equipment status information, wherein the equipment status information may include: equipment wear degree information, equipment blockage degree information and equipment leakage degree information, etc.

[0031] The emulsion property information may include: the viscosity information of the emulsion, the density information of the emulsion, the surface tension information of the emulsion, etc.

[0032] The ambient temperature information may be the temperature information in the emulsion pipeline.

[0033] The pipeline characteristic information may include: the diameter, length, material of the emulsion pipeline and the roughness information of the inner wall of the emulsion pipeline.

[0034] Exemplarily, the emulsion flow correction information may be determined based on the emulsion property information, equipment status information, pipeline characteristic information, and the like.

[0035] Step S120, regulating the emulsion flow valve to a target opening according to the emulsion target flow information, so that the difference between the emulsion flow rate flowing out of the emulsion flow valve and the emulsion target flow information is less than a preset difference.

[0036] It should be noted that the target opening is positively correlated with the target flow rate information of the emulsion, that is, the larger the target flow rate information of the emulsion is, the larger the target opening is.

[0037] For example, the preset difference can be determined according to the emulsion residual amount requirement, the finished product quality requirement of the rolled product, or according to the actual production experience of the enterprise. It should be noted that the preset difference is negatively correlated with the emulsion residual amount requirement or the finished product quality requirement of the rolled product, that is, the higher the emulsion residual amount requirement or the finished product quality requirement of the rolled product, the smaller the preset difference is controlled.

[0038] The emulsion flow control method proposed in the present application includes: obtaining emulsion target flow information, wherein the emulsion target flow information is determined based on the emulsion preset flow information and the emulsion flow correction information; according to the emulsion target flow information, regulating the emulsion flow valve to the target opening, so that the difference between the emulsion flow flowing out of the emulsion flow valve and the emulsion target flow information is less than the preset difference. The present application can improve the determination accuracy of the emulsion target flow information based on the emulsion preset flow information and the emulsion flow correction information, thereby realizing the opening control accuracy of the emulsion flow valve, so as to reduce the difference between the emulsion flow flowing out of the emulsion flow valve and the emulsion target flow information, thereby improving the control accuracy of the emulsion flow in the metal processing process, reducing the emulsion residue in the metal processing process, and improving the quality of the finished product. At the same time, the present application does not need to add large hardware equipment, avoids linkage control between equipment, simplifies the control steps, and can improve the control efficiency of the emulsion flow valve opening, thereby improving the control efficiency of the emulsion flow in the metal processing process.

[0039] In some feasible embodiments, the above method also includes: obtaining rolling speed information, flow information of a first preset position and pressure information of a second preset position, the first preset position being within a preset distance from the inlet end of the emulsion flow valve to the direction of emulsion flow, and the second preset position being within a preset distance from the outlet end of the emulsion flow valve to the direction of emulsion flow; determining the preset flow information of the emulsion based on the rolling speed information; and determining the emulsion flow correction information based on the flow information and the pressure information.

[0040] Exemplarily, the rolling speed information can be determined based on the operating power information of the rolling mill, the rolling force information, the pulling speed information of the metal to be processed, etc. In some examples, the rolling speed information is positively correlated with the operating power information, the rolling force information, and the pulling speed information of the metal to be processed.

[0041] Exemplarily, the preset emulsion flow rate information is positively correlated with the rolling speed information.

[0042] For example, Figure 2 A schematic diagram of a first preset position and a second preset position provided in an embodiment of the present application. Figure 2 As shown, the flow information of the first preset position A and the pressure information of the second preset position B are obtained. According to the pressure information of the second preset position B, the flow information of the second preset position B is determined. According to the difference between the flow information of the second preset position B and the flow information of the first preset position A, the emulsion flow correction information is determined.

[0043] It should be noted that the above-mentioned preset distance can be determined according to the accuracy requirements of the emulsion flow correction information, the accuracy requirements of the emulsion target flow information, the accuracy requirements of the emulsion flow valve opening control, etc. Among them, the above-mentioned preset distance is negatively correlated with the accuracy requirements of the emulsion flow correction information, the accuracy requirements of the emulsion target flow information, and the accuracy requirements of the emulsion flow valve opening control, that is, the higher the accuracy requirements of the emulsion flow correction information, the accuracy requirements of the emulsion target flow information, and the accuracy requirements of the emulsion flow valve opening control, the smaller the above-mentioned preset distance is controlled.

[0044] In some instances, such as Figure 2 As shown, the running speed information of the roller 10 can be obtained, and then the above-mentioned rolling speed information can be determined. According to the above-mentioned rolling speed information, the preset flow information of the emulsion is determined. According to the numerical information of the flow meter 50 at the first preset position A and the numerical information of the pressure gauge 20 at the second preset position B, the emulsion flow correction information is determined. Then, according to the above-mentioned emulsion preset flow information and the above-mentioned emulsion flow correction information, the emulsion target flow information is determined. According to the above-mentioned emulsion target flow information, the above-mentioned emulsion flow valve 30 is regulated to the target opening, so that the difference between the emulsion flow flowing out of the emulsion flow valve 30 and the emulsion target flow information is less than the preset difference.

[0045] In some examples, the emulsion flow valve 30 may be a CV valve.

[0046] It should be noted that a preset valve body 40 may be added at a preset distance from the emulsion flow valve 30 to achieve hierarchical control of the emulsion flow. In some examples, the preset valve body 40 may be an SV valve or a CV valve, which is not specifically limited here.

[0047] It should be noted that before starting rolling or after tail rolling, the preset valve body 40 and the emulsion flow valve 30 must maintain a certain opening to ensure that the emulsion cools and lubricates the metal to be processed throughout the entire processing process, thereby avoiding wear of the metal to be processed during the processing process.

[0048] Therefore, the above method can improve the correlation between the preset emulsion flow information and the rolling speed information, accurately determine the emulsion flow correction information according to the flow information and pressure information, thereby improving the determination accuracy of the emulsion target flow information, improving the control accuracy of the emulsion flow flowing out through the emulsion flow valve, and improving the adaptability of the emulsion flow flowing out through the emulsion flow valve to the rolling speed information, thereby improving the control accuracy of the emulsion flow during the non-uniform speed operation of equipment such as start-up rolling or tail-swinging rolling, saving emulsion resources, reducing emulsion residues caused by factors such as poor finished plate shape, avoiding the formation of emulsion spots on the finished product, improving the quality of the finished product, and improving the product yield rate.

[0049] In some feasible implementations, the above method further includes: obtaining rolling acceleration information within a preset time; and regulating the opening acceleration of the emulsion flow valve within the preset time according to the rolling acceleration information, wherein the opening acceleration is positively correlated with the rolling acceleration information.

[0050] Exemplarily, the preset time can be determined according to the precision requirement of the emulsion flow valve opening control, or the hardware computing capability or the hardware energy saving requirement. In some examples, the preset time is negatively correlated with the precision requirement of the emulsion flow valve opening control or the hardware computing capability, that is, the higher the precision requirement of the emulsion flow valve opening control or the hardware computing capability, the shorter the preset time. The preset time is positively correlated with the hardware energy saving requirement, that is, the higher the hardware energy saving requirement, the longer the preset time.

[0051] Exemplarily, the rolling acceleration information can be determined based on the rolling mill's operating power change information, rolling force change information, the pull speed change information of the metal to be processed, and the rolling speed information within a preset time. In some examples, the numerical information of the rolling acceleration is positively correlated with the rolling mill's operating power change information, rolling force change information, the pull speed change information of the metal to be processed, etc. within a preset time.

[0052] In some examples, the opening acceleration is a rate of change of the opening of the emulsion flow valve within a preset time.

[0053] For example, Figure 3 This is a control effect diagram of an emulsion target flow information provided in an embodiment of the present application. Figure 3 As shown, curve 100a is a rolling speed information change curve, and curve 100b is an emulsion target flow information change curve. It should be noted that the slope of curve 100a is rolling acceleration information, and the slope of curve 100b is emulsion target flow information change rate information. In a feasible implementation, the emulsion target flow information change rate information can be determined based on the rolling acceleration information within the preset time, and the target opening acceleration of the emulsion flow valve can be determined based on the emulsion target flow information change rate information, so as to adjust the opening acceleration of the emulsion flow valve within the preset time to the target opening acceleration.

[0054] Therefore, the above method determines the preset flow information of the emulsion according to the rolling speed information, and then determines the target flow information of the emulsion according to the preset flow information of the emulsion and the emulsion flow correction information, and adjusts the emulsion flow valve to the target opening, so that the difference between the emulsion flow flowing out of the emulsion flow valve and the target flow information of the emulsion is less than the preset difference, and adjusts the opening acceleration of the emulsion flow valve within the preset time according to the rolling acceleration information, so as to realize the dual regulation of the opening of the emulsion flow valve and the opening change rate, further improve the adaptability of the emulsion flow flowing out of the emulsion flow valve, the emulsion flow change rate and the rolling speed information, and the rolling acceleration information, and then improve the control accuracy of the emulsion flow and the emulsion flow change rate during the speed change process of the equipment such as the start-up rolling or the tail-swinging rolling, so as to further save the emulsion resources, reduce the emulsion residue caused by factors such as the poor plate shape of the finished product, avoid the formation of emulsion spots on the finished product, improve the quality of the finished product, and improve the product yield rate.

[0055] In some feasible embodiments, the above method also includes: when the rolling acceleration information is greater than a first preset acceleration threshold, controlling the opening of the emulsion flow valve to increase; when the rolling acceleration information is less than a second preset acceleration threshold, controlling the opening of the emulsion flow valve to decrease, wherein the first preset acceleration threshold is greater than 0, and the second preset acceleration threshold is less than or equal to 0.

[0056] Exemplarily, the first preset acceleration threshold and the second preset acceleration threshold can be determined according to the actual production experience of the enterprise, the characteristics of the metal to be processed, and the ambient temperature. In some examples, the characteristics of the metal to be processed may include: plasticity, corrosion resistance, machinability, etc. of the metal to be processed.

[0057] It should be noted that the gradient correspondence information between the rolling acceleration information and the preset flow rate information of the emulsion can be constructed based on the actual production experience of the enterprise, the characteristics of the metal to be processed, the determination of the ambient temperature, the quality requirements of the finished product, etc. According to the gradient correspondence information between the rolling acceleration information and the preset flow rate information of the emulsion and the emulsion flow correction information, the gradient correspondence information between the rolling acceleration information and the target flow rate of the emulsion is determined. According to the gradient correspondence information between the rolling acceleration information and the target flow rate of the emulsion, the gradient correspondence information from the emulsion flow valve to the target opening is determined so that the difference between the emulsion flow rate flowing out of the emulsion flow valve and the emulsion target flow rate information is less than the preset difference. Among them, the first preset acceleration threshold is the first inflection point acceleration threshold at which the current emulsion flow flowing out of the emulsion flow valve during the accelerated rolling stage cannot meet the lubrication and cooling requirements of the metal to be processed under the current rolling acceleration or rolling speed. The second preset acceleration threshold is the deceleration rolling stage. The current emulsion flow rate flowing out through the emulsion flow valve can meet the lubrication and cooling requirements of the metal to be processed under the current rolling acceleration or rolling speed. However, due to the excessive emulsion flow rate, excessive emulsion residue occurs, causing the second inflection point acceleration threshold of emulsion spot defects on the surface of the finished product.

[0058] In some examples, when the rolling acceleration information is greater than the second preset acceleration threshold and less than or equal to the first preset acceleration threshold, the device is in a state where, based on the gradient correspondence information between the rolling acceleration information and the target emulsion flow rate, if it can be determined that the emulsion flow rate corresponding to the current emulsion flow valve opening can meet the lubrication and cooling requirements of the metal to be processed under the current rolling acceleration or rolling speed, the opening of the current emulsion flow valve is not regulated. On the contrary, when the rolling acceleration information is greater than the first preset acceleration threshold, if it is determined that the emulsion flow rate corresponding to the current emulsion flow valve opening cannot meet the lubrication and cooling requirements of the metal to be processed under the current rolling acceleration or rolling speed, the opening of the current emulsion flow valve is controlled to increase.

[0059] When the rolling acceleration information is less than the second preset acceleration threshold, the equipment is in the deceleration rolling stage. According to the gradient correspondence information between the rolling acceleration information and the emulsion target flow rate, if it can be determined that the emulsion flow rate corresponding to the current emulsion flow valve opening can meet the lubrication and cooling requirements of the metal to be processed under the current rolling acceleration or rolling speed, but the emulsion flow rate is too large, it will cause excessive emulsion residue and cause emulsion spot defects on the surface of the finished product, then the opening of the emulsion flow valve is controlled to be reduced.

[0060] Therefore, the above method can realize precise control of the opening of the emulsion flow valve according to the rolling acceleration information, the first preset acceleration threshold and the second preset acceleration threshold, improve the matching of the emulsion flow flowing out of the emulsion flow valve at different rolling stages with the cooling demand and lubrication demand of the metal to be processed, and ensure sufficient emulsion flow in the speed-up rolling stage, such as the start-up rolling stage, and avoid excessive emulsion flow in the deceleration rolling stage, such as the tail-swinging rolling stage, which leads to excessive emulsion residue and product surface defects. In some feasible embodiments, the above method also includes: determining the time information of the emulsion flow valve opening to the target opening according to the rolling acceleration information and the preset rolling speed threshold information; and controlling the emulsion flow valve to open to the target opening at the corresponding time according to the time information.

[0061] For example, the above rolling speed threshold information can be determined based on the actual production experience of the enterprise, the characteristics of the metal to be processed, the ambient temperature, the quality requirements of the finished product, etc.

[0062] In some examples, the gradient correspondence information between the rolling speed information and the preset flow rate information of the emulsion can be constructed based on the actual production experience of the enterprise, the characteristics of the metal to be processed, the determination of the ambient temperature, the quality requirements of the finished product, etc. According to the gradient correspondence information between the rolling speed information and the preset flow rate information of the emulsion and the emulsion flow correction information, the gradient correspondence information between the rolling speed information and the target flow rate of the emulsion is determined. According to the gradient correspondence information between the rolling speed information and the target flow rate of the emulsion, the gradient correspondence information from the emulsion flow valve to the target opening is determined so that the difference between the emulsion flow rate flowing out of the emulsion flow valve and the emulsion target flow rate information is less than the preset difference. Among them, the above-mentioned rolling speed threshold information is the inflection point threshold of the rolling speed information when the current emulsion flow rate flowing out of the emulsion flow valve cannot meet the lubrication and cooling requirements of the metal to be processed at the current rolling speed or the current emulsion flow rate flowing out of the emulsion flow valve can meet the lubrication and cooling requirements of the metal to be processed at the current rolling speed, but due to the excessive emulsion flow, too much emulsion remains, causing emulsion spot defects on the surface of the finished product.

[0063] Based on the above-mentioned rolling acceleration information, the preset rolling speed threshold information, and the gradient correspondence information between the rolling speed information and the target emulsion flow rate, the moment information at which the emulsion flow valve needs to be controlled to open to the target opening can be determined, so that according to the above-mentioned moment information, the emulsion flow valve is controlled to accelerate opening or decelerate closing to the target opening, so that at the above-mentioned moment information, the emulsion flow rate flowing out of the emulsion flow valve matches the cooling requirement, lubrication requirement and quality requirement of the metal to be processed corresponding to the above-mentioned moment information.

[0064] Therefore, the above method can avoid the delay in the emulsion flow valve opening control caused by the information processing and signal transmission hierarchical processing control process in the control process of the emulsion flow valve, improve the timeliness of the emulsion flow valve opening control, thereby improving the timeliness of the emulsion flow control, and improving the matching of the emulsion flow flowing out of the emulsion flow valve at the corresponding moment with the cooling demand, lubrication demand and quality demand of the metal to be processed, thereby improving product quality.

[0065] In some feasible embodiments, the above method also includes: determining the emulsion flow difference information based on the flow information of the first preset position and the pressure information of the second preset position; when the emulsion flow difference information at the target position is greater than or equal to the preset flow difference information, controlling the emulsion flow valve at the target position to close.

[0066] In a feasible implementation, emulsion flow valves can be arranged at multiple positions of the emulsion flow pipeline according to actual production needs, and the first preset position flow information and the second preset position pressure information can be monitored at the corresponding positions of the multiple emulsion flow valves. In some examples, when the enterprise arranges emulsion flow valves at multiple positions of the emulsion flow pipeline according to actual production needs, the emulsion flow difference information corresponding to each emulsion flow valve can be determined according to the first preset position flow information and the second preset position pressure information corresponding to each emulsion flow valve. When the emulsion flow difference information corresponding to the emulsion flow valve at the target position is greater than or equal to the preset flow difference information, it is judged that there is an abnormal pipeline leakage at the target position, and the emulsion flow valve here is controlled to be closed. It should be noted that the above-mentioned preset flow difference information can be determined according to the actual production experience of the enterprise or the enterprise's monitoring accuracy requirements for pipeline leakage. In some examples, the above-mentioned preset flow difference information is negatively correlated with the monitoring accuracy of the above-mentioned pipeline leakage, that is, the higher the monitoring accuracy of the pipeline leakage, the smaller the preset flow difference information.

[0067] Therefore, the above method can be achieved when the enterprise arranges emulsion flow valves at multiple positions of the emulsion flow pipeline according to actual production needs. According to the comparison results of the emulsion flow difference information corresponding to each emulsion flow valve and the preset flow difference information, the position of the abnormal pipeline leakage in the emulsion pipeline can be accurately determined, and then the emulsion flow valve at the target position can be accurately controlled to be closed, thereby improving the efficiency of troubleshooting emulsion pipeline abnormalities, avoiding abnormal increase in emulsion flow, large amount of emulsion residue, and formation of emulsion spots on the surface of the finished product due to pipeline leakage, thereby reducing the defective product rate.

[0068] In a feasible implementation, a visual emulsion flow monitoring interface can also be formed based on the company's emulsion flow pipeline, the layout position of the emulsion flow valve, the flow information of the first preset position and the pressure information of the second preset position. When it is judged that a pipeline leakage occurs at the target position, a frequency flashing abnormal signal occurs at the corresponding position of the above-mentioned visual emulsion flow monitoring interface, and a pipeline leakage alarm is issued at the same time to remind the staff to inspect the target position in time, thereby improving the efficiency of pipeline repair.

[0069] In some feasible embodiments, the above method also includes: obtaining one or more of the historical rolled part emulsion residual parameters, the historical rolled part surface quality parameters, and the emulsion cleanliness parameters; correcting the emulsion target flow information according to one or more of the historical rolled part emulsion residual parameters, the historical rolled part surface quality parameters, and the emulsion cleanliness parameters; and regulating the emulsion flow valve to a target opening according to the corrected emulsion target flow information so that the difference between the emulsion flow flowing out of the emulsion flow valve and the emulsion target flow information is less than a preset difference.

[0070] It should be noted that by correcting the emulsion target flow information based on one or more of the historical rolled part emulsion residue parameters, historical rolled part surface quality parameters, and emulsion cleanliness parameters, it is beneficial to improve the matching degree of the emulsion target flow information with the output historical rolled part emulsion residue, historical rolled part surface quality, and emulsion cleanliness parameters, and then achieve precise control of the opening of the current emulsion flow valve based on historical rolling experience and emulsion characteristics, thereby improving the quality of the finished products of subsequent parts to be rolled.

Figure 4 This is a structural schematic diagram of an emulsion flow control device 200 provided in an embodiment of the present application. Figure 4 The emulsion flow control device 200 may include: an acquisition unit 210 and a control unit 220

[0072] The acquisition unit 210 is used to acquire the target flow rate information of the emulsion, wherein the target flow rate information of the emulsion is determined based on the preset flow rate information of the emulsion and the emulsion flow rate correction information.

[0073] The control unit 220 is used to control the emulsion flow valve to a target opening according to the emulsion target flow information, so that the difference between the emulsion flow rate flowing out of the emulsion flow valve and the emulsion target flow information is less than a preset difference.

Figure 3 As shown, the electronic device 300 includes a processor 310 and a memory 320, wherein the memory 320 stores computer program instructions, and the computer program instructions are used by the processor 310 to execute any one of the emulsion flow control methods of the first aspect when the processor 310 is running.

[0075] According to a fourth aspect of the present application, the present application further provides a storage medium on which program instructions are stored, and the program instructions are used to execute the emulsion flow control method described in any one of the first aspects when running. The storage medium may include, for example, a storage component of a tablet computer, a hard disk of a computer, a read-only memory (ROM), an erasable programmable read-only memory (EPROM), a portable compact disk read-only memory (CD-ROM), a USB memory, or any combination of the above storage media. The computer-readable storage medium may be any combination of one or more computer-readable storage media.

[0076] A person skilled in the art can understand the specific details and beneficial effects of the emulsion flow control device by reading the above description of the emulsion flow control method, which will not be described here for the sake of brevity.
