[0025] In some embodiments, Figure 1 As shown, an embodiment of the present application provides a control method for pickling equipment, comprising:

[0026] Step S101, obtaining the heating efficiency of the pickling equipment during the process of the pickling equipment heating the steel;

[0027] Step S102, obtaining the size data of the steel material and obtaining a preset speed supplement coefficient;

[0028] Step S103, determining the operating speed range of the pickling equipment according to the heating efficiency, the size data and the speed supplement coefficient;

[0029] Step S104, adjusting the speed of the pickling equipment for pickling the steel so that the speed of the steel is within the operating speed range.

[0030] In this embodiment, a control method for a pickling equipment is proposed, wherein the pickling equipment is a device for pickling steel.

[0031] For example, during the operation of the pickling equipment, the steel needs to be heated.

[0032] In the process of the pickling equipment heating the steel, the heating efficiency of the pickling equipment is obtained, wherein the heating efficiency represents the ability of the pickling equipment to heat the steel.

[0033] Exemplarily, the heating efficiency may be the heating capacity designed for the pickling equipment, which may be specifically 720 tons / hour.

[0034] The dimension data of the steel material is obtained, and a preset speed supplement coefficient is obtained, wherein the dimension data is the specific data of the steel material size, and the speed supplement coefficient is the coefficient regarding the pickling speed of the pickling equipment.

[0035] For example, the dimension data may include data such as the thickness and width of the steel material.

[0036] The operating speed range of the pickling equipment is determined based on the heating efficiency, dimensional data and speed supplement coefficient, where the operating speed range is the speed range of the pickling equipment for pickling steel.

[0037] Illustratively, the operating speed range may include a maximum speed at which the pickling equipment can pickle steel.

[0038] Exemplarily, process section speed = coefficient K×(720×1000000) / (60×7.85×thickness×width), wherein the operating speed range may include the process section speed, the coefficient K is the speed supplement coefficient, and the dimensional data includes the thickness and width of the steel.

[0039] Adjust the speed of pickling steel in the pickling equipment so that the speed of the steel is within the operating speed range.

[0040] It should be noted that if the speed of the pickling equipment for pickling steel is too high, the effect of the pickling equipment for pickling steel may be reduced, causing oxides and other impurities to remain on the surface of the steel. However, this embodiment determines the operating speed range of the pickling equipment based on the heating efficiency, dimensional data and speed supplement coefficient, so that the pickling equipment can pickle the steel at the maximum speed while ensuring the effect of the pickling equipment for pickling steel and avoiding the retention of oxides and other impurities on the surface of the steel.

[0041] The control method of the pickling equipment in this embodiment determines the operating speed range of the pickling equipment according to the heating efficiency, dimensional data and speed supplement coefficient, and then adjusts the speed of the pickling equipment for pickling steel to make the speed of the steel within the operating speed range, thereby improving the pickling efficiency of the pickling equipment for steel and reducing the retention rate of oxidizing substances in the steel after pickling.

[0042] In some embodiments, a control method for pickling equipment is provided in an embodiment of the present application, and the operating speed range of the pickling equipment is determined according to the heating efficiency, the size data and the speed supplement coefficient, including:

[0043] Step S201, determining the operating speed threshold according to the heating efficiency, the size data and the speed supplement coefficient;

[0044] Step S202, determining the operating speed range according to the operating speed threshold and a preset speed value.

[0045] In this embodiment, the heating efficiency, the dimension data and the speed supplement coefficient are calculated to obtain an operating speed threshold, wherein the operating speed threshold is a speed threshold for pickling steel by the pickling equipment.

[0046] Exemplarily, the operating speed threshold may be the maximum speed at which the pickling equipment pickles steel.

[0047] Exemplarily, the running speed threshold may be 1 meter / second.

[0048] The operating speed range is determined according to the operating speed threshold and the preset speed value.

[0049] Exemplarily, the speed value may be 0.1 m / s, and the difference between the operating speed threshold and the preset speed value is calculated to obtain an operating speed range of 0.9 m / s to 1 m / s.

[0050] The control method of the pickling equipment in this embodiment determines the operating speed range according to the operating speed threshold and the preset speed value, thereby ensuring the data accuracy of the operating speed range, thereby improving the pickling efficiency of the pickling equipment for steel, and reducing the retention rate of oxidizing substances in the steel after pickling.

[0051] In some embodiments, an embodiment of the present application provides a control method for pickling equipment, obtaining a preset speed supplement coefficient, including:

[0052] Step S301, detecting the temperature of the acid tank to obtain a first temperature;

[0053] Step S302, detecting the temperature of the steel surface to obtain a second temperature;

[0054] Step S303: determining a speed supplement coefficient according to the first temperature and the second temperature.

[0055] In this embodiment, the pickling equipment includes an acid tank, which is a device for containing acid solution. The temperature of the acid tank is detected to obtain a first temperature, wherein the first temperature is the acid tank temperature.

[0056] Exemplarily, a temperature sensor is provided on the acid tank, and the temperature of the acid tank is measured by the temperature sensor to obtain the first temperature.

[0057] Exemplarily, the pickling equipment may include a plurality of acid tanks, and the temperatures of the plurality of acid tanks are checked respectively to obtain the first temperature.

[0058] The temperature of the surface of the steel material is detected to obtain a second temperature, wherein the second temperature is the surface temperature of the steel material.

[0059] Exemplarily, the pickling equipment may include a temperature sensor, and the temperature of the surface of the steel material is detected by the temperature sensor to obtain the second temperature.

[0060] A speed supplement coefficient is determined based on the first temperature and the second temperature.

[0061] It should be noted that the temperature of steel will affect the pickling effect of steel. For example, the surface temperature of the strip is low in winter and the pickling effect is poor. This application determines the speed supplement coefficient according to the first temperature and the second temperature, and adjusts the pickling speed of the pickling equipment based on the speed supplement coefficient to supplement the influence of the first temperature and the second temperature on the steel pickling process, thereby ensuring the pickling effect of the steel and reducing the retention rate of oxidizing substances in the steel after pickling.

[0062] The control method of the pickling equipment in this embodiment determines the speed supplement coefficient according to the first temperature and the second temperature, and adjusts the pickling speed of the pickling equipment based on the speed supplement coefficient to supplement the influence of the first temperature and the second temperature on the pickling process of the steel, thereby ensuring the pickling effect of the steel and reducing the retention rate of oxidizing substances in the steel after pickling.

[0063] In some embodiments, an embodiment of the present application provides a control method for a pickling equipment, which adjusts the speed of the pickling equipment for pickling steel so that the speed of the steel is within the operating speed range, and the method further includes:

[0064] Step S401, detecting the steam pressure of the pickling equipment to obtain a first steam pressure value;

[0065] Step S402: when the first steam pressure value is less than the pressure threshold, output a pressure abnormality warning.

[0066] In this embodiment, the steam pressure of the pickling equipment will also affect the pickling effect of the steel, so it is necessary to detect the steam pressure of the pickling equipment to obtain a first steam pressure value, wherein the first steam pressure value is a real-time steam pressure value of the pickling equipment.

[0067] Exemplarily, the pickling equipment includes a pressure sensor, and the steam pressure of the pickling equipment is detected by the pressure sensor to obtain a first steam pressure value.

[0068] When the first steam pressure value is less than the pressure threshold, it indicates that the steam pressure of the pickling equipment is abnormal, and a pressure abnormality warning is output, wherein the pressure abnormality warning is a signal indicating that the steam pressure of the pickling equipment is abnormal.

[0069] For example, when the first steam pressure value is less than the pressure threshold, it indicates that the steam pressure of the pickling equipment is too low, which will affect the pickling effect of the steel.

[0070] Exemplarily, when the first steam pressure value is less than the pressure threshold, a pressure abnormality warning is issued to the staff.

[0071] The control method for the pickling equipment in this embodiment indicates that the steam pressure of the pickling equipment is abnormal when the first steam pressure value is less than the pressure threshold, and outputs a pressure abnormality warning to maintain the steam pressure of the pickling equipment normal, thereby ensuring the pickling effect of the steel and reducing the retention rate of oxidizing substances in the steel after pickling.

[0072] In some embodiments, an embodiment of the present application provides a control method for a pickling equipment, which adjusts the speed of the pickling equipment for pickling steel so that the speed of the steel is within the operating speed range, and the method further includes:

[0073] Step S501, detecting the speed of the steel material to obtain a first speed;

[0074] Step S502: when the first speed is not within the operating speed range, output a speed abnormality warning.

[0075] In this embodiment, after adjusting the speed of the pickling equipment for pickling steel, the speed of the steel is detected in real time to obtain a first speed, wherein the first speed is the speed of the pickling equipment for pickling steel.

[0076] Exemplarily, the pickling equipment includes a speed sensor, which detects the speed of the steel in real time to obtain the first speed.

[0077] When the first speed is not within the operating speed range, it indicates that the speed of pickling steel by the pickling equipment is abnormal, and a speed abnormality warning is output, wherein the speed abnormality warning is a signal indicating that the speed of pickling steel by the pickling equipment is abnormal.

[0078] Exemplarily, when the first speed is not within the operating speed range, a speed abnormality warning is issued to the staff.

[0079] The control method of the pickling equipment in this embodiment, when the first speed is not within the operating speed range, indicates that the speed of the pickling equipment for pickling steel is abnormal, and outputs a speed abnormality warning to maintain the pickling speed of the pickling equipment at a normal level, thereby ensuring the pickling effect of the steel and reducing the retention rate of oxidizing substances in the steel after pickling.

[0080] In some embodiments, an embodiment of the present application provides a control method for pickling equipment, which obtains the heating efficiency of the pickling equipment, including:

[0081] Step S601, during the operation of the pickling equipment, obtaining equipment parameters of the pickling equipment;

[0082] Step S602, determining the heating efficiency according to the equipment parameters.

[0083] In this embodiment, during the operation of the pickling equipment, equipment parameters of the pickling equipment are obtained, wherein the equipment parameters are operating parameters of the pickling equipment.

[0084] Determine the heating efficiency based on the equipment parameters.

[0085] Exemplarily, the equipment parameters may include design parameters of the pickling equipment, and the heating efficiency may be determined by detecting the design parameters.

[0086] For example, 1. The heating capacity of the pickling design is 720 tons / hour. If the process section speed is too fast, it will cause the problem of insufficient pickling of the strip. Design a process section speed limit model to calculate the maximum speed of the process section when the strip passes through pickling according to the thickness and width of the strip. Specific formula: process section speed = coefficient K*(720×1000000) / (60×7.85×thickness×width). According to the calculated process section speed, the maximum operating speed is limited to ensure the pickling effect. Among them, K is 1.02. The compensation coefficient calculated based on the curling temperature of the strip raw material and the temperature of the three acid tanks can be adjusted according to different processes.

[0087] 2. The surface temperature of strip steel in winter is 40℃ lower than that in summer on average, which affects the reactivity of free acid and requires stronger pickling capacity. Two different pickling models are established:

[0088] Spring, summer and autumn: 1# tank temperature 85℃, 2# tank temperature 82℃, 3# tank temperature 80℃, high pressure 0.3Mpa, low pressure 0.15Mpa.

[0089] Winter: 1# tank temperature 88℃, 2# tank temperature 85℃, 3# tank temperature 82℃, high pressure 0.3Mpa, low pressure 0.2Mpa. 1# tank small circulation speed increased to 1250 rpm.

[0090] 3. Increase steam pressure monitoring and stable output:

[0091] By connecting the steam pressure to the main interface display, the operator can view the real-time pressure changes.

[0092] Add an alarm prompt when the steam pressure is lower than 0.4Mpa, and pickling speed is not allowed to be increased.

[0093] The steam delivery pipeline was replaced from carbon steel pipe to stainless steel to prevent leakage.

[0094] The steam heating pipe has a thicker insulation layer to prevent large heat losses in winter.

[0095] Add a set of preheated DN15 electric control valves to the main line, and program the valve opening to avoid

[0096] 4. The original leveling roller was made of high-strength alloy steel (50CrMo4), the coating was unstable and prone to peeling, which affected the local phosphorus breaking effect. In conjunction with the manufacturer and inspection, the leveling roller surface material was optimized and changed to tungsten carbide (WC). WC material is more wear-resistant and has a longer service life, which meets the current production needs of acid rolling.

[0097] 5. A large amount of iron powder is generated in the straightening machine, and the fallen iron oxide scale remains between the roller support surfaces, reducing the overall contact area, causing excessive local force and damage to the roller surface. An air purge device is added to the lower surface of the No. 1 and No. 2 bending units to prevent iron powder accumulation.

[0098] 6. Add spare acid analysis and online switching functions to pickling tank 1#:

[0099] During maintenance, add pipelines to the small circulation on site, connect a pipe to connect the conductivity pipe in parallel with the pipe at the outlet of another set of mass flow meters, and close the manual valve of the pipe in the standby state to prevent the silicon mud in the acid from contaminating the two sets of conductivity at the same time.

[0100] 7. Add online switching function. When the detection value is inaccurate, you can switch the program to use backup detection data with one click to ensure the accuracy of the detection and achieve accurate detection of acid discharge 24 hours a day.

[0101] The control method of the pickling equipment in this embodiment obtains the heating efficiency of the pickling equipment and determines the operating speed range of the pickling equipment based on the heating efficiency, thereby ensuring the pickling effect of the steel and reducing the retention rate of oxidizing substances in the steel after pickling.

[0108] For example, during the operation of the pickling equipment, the steel needs to be heated.

[0109] In the process of the pickling equipment heating the steel, the heating efficiency of the pickling equipment is obtained, wherein the heating efficiency represents the ability of the pickling equipment to heat the steel.

[0110] Exemplarily, the heating efficiency may be the heating capacity designed for the pickling equipment, which may be specifically 720 tons / hour.

[0116] Adjust the speed of pickling steel in the pickling equipment so that the speed of the steel is within the operating speed range.

[0117] It should be noted that if the speed of the pickling equipment for pickling steel is too high, the effect of the pickling equipment for pickling steel may be reduced, causing oxides and other impurities to remain on the surface of the steel. However, this embodiment determines the operating speed range of the pickling equipment based on the heating efficiency, dimensional data and speed supplement coefficient, so that the pickling equipment can pickle the steel at the maximum speed while ensuring the effect of the pickling equipment for pickling steel and avoiding the retention of oxides and other impurities on the surface of the steel.
