Description

Technical Field

[0001] The present invention belongs to the technical field of pipe production, and in particular relates to a pipe anti-corrosion control method and system. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Steel corrosion accounts for a high proportion of annual steel production, and the economic losses caused by corrosion are high. Therefore, anti-corrosion treatment of steel pipes is extremely important.

[0004] At present, anti-corrosion treatment of pipes is related to the application scope and service life of pipes. Anti-corrosion processes and technologies are a crucial link in the pipe production process; coating protection of pipes is an effective way to prevent corrosion of steel pipes.

[0005] The epoxy coating anti-corrosion method refers to a steel-plastic composite product with anti-corrosion properties that uses a pre-treated steel pipe as the base pipe, and then coats the inner and outer surfaces of the pipe with sintered epoxy powder after heating. On this basis, the improved outer double-layer epoxy coating anti-corrosion method refers to the use of a double-layer epoxy powder coating on the outer layer, the bottom layer of which is an anti-corrosion epoxy coating with excellent anti-corrosion properties and adhesion, and the surface layer is a modified coating with special functionality. It can provide long-lasting anti-corrosion performance and can provide the pipeline with excellent mechanical damage resistance, scratch resistance and other special properties.

[0006] The epoxy powder coating process for pipes requires strict requirements, with the pipe temperature controlled at 200°C ±5%. This is because temperature rises and falls with a delay and is easily affected by seasonal and time-dependent ambient temperature fluctuations. The current mainstream production method involves V-shaped rollers conveying the pipe to a heating stage at a fixed speed via a reducer, where the heater heats the pipe at a fixed power. After heating, the pipe is then sprayed with epoxy powder in a subsequent epoxy powder coating machine. The adhesive is then applied to the adhesive extruder, and then to the polyethylene extruder, where the polyethylene adheres to the pipe's outer surface. The pipe then rapidly cools in a cooling spray stage to ensure reliable adhesion between the epoxy powder and the polyethylene.

[0007] However, the heating link, epoxy powder spraying link, adhesive extrusion link, polyethylene extrusion link and cooling spray link are all open-loop controlled. The power and opening of each link are determined by a single on-site debugging. The changes of each link cannot be accurately controlled as the ambient temperature changes, and closed-loop control cannot be formed. Therefore, it is easy to cause unqualified spraying, material waste and even scrap, resulting in industrial waste and increased production costs. Summary of the Invention

[0008] To solve the above problems, the present invention proposes a pipe anti-corrosion control method and system. The method calculates the benchmark pipe production speed through the pipe temperature and pipe diameter, and completes the closed-loop control of the corrosion protection of the transported pipes by calculating the anti-corrosion action parameters, so that the output power of each production link meets the needs of the current actual pipe data, ensuring product quality and avoiding the output of waste.

[0016] As a further technical limitation, the reference speed of the pipe is inversely proportional to the diameter of the pipe, that is, the reference speed decreases as the diameter of the pipe increases.

[0017] As a further technical limitation, when the obtained pipe temperature is within the pipe temperature threshold range, the benchmark production speed of the pipe is calculated in combination with the determined pipe transportation benchmark speed; when the pipe temperature is not within the pipe temperature threshold range, the pipe transportation motor does not run, that is, the pipe is not transported for corrosion protection.

[0018] As a further technical limitation, before performing closed-loop control of corrosion protection of the transported pipes, the pipes are heated. When and only when the pipe temperature exceeds a preset pipe temperature, the heater is turned off for heating; otherwise, the heater is turned on to heat the pipes.

[0019] As a further technical limitation, the anti-corrosion action parameters are at least related to the opening of the epoxy powder spraying proportional valve, the adhesive extrusion speed, the polyethylene extrusion speed and the water output of the cooling valve.

[0020] Furthermore, the opening of the epoxy powder spraying proportional valve controls the epoxy powder spraying speed, and the epoxy powder spraying speed is related to the benchmark production speed, the current pipe temperature and the epoxy powder spraying proportional valve opening adjustment coefficient; the adhesive extrusion speed is related to the benchmark production speed, the adhesive extrusion coefficient and the pipe diameter; the polyethylene extrusion speed is directly proportional to the adhesive extrusion speed; the water output of the cooling valve is related to the opening of the proportional valve, and the opening of the proportional valve is related to the benchmark production speed, the pipe diameter and the current temperature of the polyethylene coating.

[0026] The control module is configured to transport the pipe at the obtained transport speed, calculate the anti-corrosion action parameters, and perform closed-loop control of the anti-corrosion of the transported pipe in combination with the obtained anti-corrosion action parameters.

[0046] Example 1

[0047] The first embodiment of the present invention introduces a pipe anti-corrosion control method.

[0048] like Figure 1 A pipe anti-corrosion control method is shown, comprising:

[0049] Obtain the pipe temperature and pipe diameter at the anti-corrosion spraying location;

[0050] Determine the pipe transportation benchmark speed based on the obtained pipe diameter;

[0051] Calculate the benchmark production speed of pipes based on pipe temperature and pipe transportation benchmark speed;

[0052] Combine the current actual pipe transportation speed and the benchmark production speed to adjust the pipe transportation speed with real-time feedback;

[0053] The pipes are transported at the obtained transport speed, the anti-corrosion action parameters are calculated, and closed-loop control of the anti-corrosion of the transported pipes is performed in combination with the obtained anti-corrosion action parameters.

[0054] The centralized anti-corrosion control method described in this embodiment is implemented based on a control system that includes at least a PLC control module, a human-machine interface touch screen, and a temperature sensor. Figure 2As shown, specifically: Each anti-corrosion equipment is controlled by its own PLC control module as the core component. The operator sets the operating parameters of the control system through the human-machine interface of the touch screen and can also monitor the current operating data. The operator enters the pipe diameter on the touch screen interface, and the control system automatically calculates parameters such as the baseline production speed and the baseline opening of the cooling proportional valve. The temperature sensor determines whether the pipe meets the anti-corrosion treatment conditions. The control system controls the pipe transportation, adhesive extrusion, polyethylene extrusion, cooling spray and other links of the anti-corrosion equipment to cooperate with each other, effectively ensuring the thickness, uniformity, adhesion and other parameters of the product's epoxy powder and polyethylene coating. By controlling the cooling time, the pipe is protected from scratches and cracks in subsequent production processes, and pits and bubbles are reduced, thereby improving product quality, reducing waste output, and saving production costs.

[0055] This embodiment takes seven pipe anti-corrosion equipment as an example to provide a detailed introduction.

[0056] Log in to the control system, on the initial page of the touch screen, click and select "Anti-corrosion Equipment Operation", enter the password for identity authentication; after logging in, enter the secondary interface, such as Figure 3 As shown, according to the information in the first column, select the workshop area where the parameters need to be modified, and enter the pipe diameter in the second column to complete the parameter modification; monitor the operation. When the system is running, the third column of the parameter modification page will display the actual temperature of the equipment after the heating stage and before the epoxy powder spraying stage; the fourth column will display the output frequency of the current adhesive extruder inverter, which directly reflects the adhesive extrusion speed; the fifth column will display the output frequency of the current polyethylene extruder inverter, which directly reflects the polyethylene extrusion speed; the sixth column will display the surface temperature of the pipe after the cooling spray stage; the operator can monitor the above parameters and data in real time on the human-machine interface.

[0057] It should be noted that sensors, such as temperature sensors, discharge speed sensors, etc., are installed in each production link, so that multiple control links in the control system can achieve closed-loop control.

[0058] In this embodiment, the pipe diameter is input and the reference production speed V is automatically calculated. G Specifically, this embodiment calculates the pipe speed V by the pipe diameter d B , that is, when the pipe diameter is 1000mm and the output frequency of the transport inverter is 45Hz, the benchmark production speed is V B =45*(1000 / d); where V B is the output frequency of the inverter at the reference pipe speed; d is the pipe diameter.

[0059] After the pipe passes through the heating stage, the temperature will naturally drop. Affected by the ambient temperature, the drop speed is not fixed. The temperature of the pipe is monitored by the sensor and the temperature signal is transmitted to the PLC. The PLC calculates the benchmark production speed V based on the pipe temperature. G ; That is, the benchmark production speed Among them, V G It changes with the temperature of the pipe and is a variable target value; V B is the benchmark transport speed; P N Indicates the actual value of the current temperature.

[0060] It should be noted that each anti-corrosion equipment in this embodiment is equipped with an online pipe measuring device to monitor parameters such as the wall thickness, uniformity, and smoothness of the pipe coating in real time to determine whether it is qualified; it is also equipped with a visual recognition device to identify defects such as scratches and bubbles on the pipe to determine whether it is qualified.

[0061] In this embodiment, the heating link adopts closed-loop control. When the temperature sensor detects that the pipe temperature is greater than 215°C, the heater is turned off; when the temperature sensor detects that the pipe temperature is less than 215°C, the heater is turned on.

[0062] The production speed of the transportation and management link in this embodiment is the transportation and management speed, which is at least related to the pipe diameter, the production reference speed, the actual transportation and management speed, the pipe temperature, and the on-site debugging coefficient.

[0063] It is controlled by PLC analog signals. In the PLC CPU module, the output range is 0 to 27648. The operator inputs the pipe diameter through the human-machine interface, and the system determines the benchmark production speed. After the heating stage and before the epoxy powder spraying stage, a temperature sensor is installed to monitor in real time whether the pipe temperature meets the range of 200 to 220°C. If the pipe temperature does not meet the requirements, the pipe transport motor stops running; if the pipe temperature meets the requirements, the pipe transport motor starts running.

[0064] ① When the temperature of the pipe meets the requirements, the temperature meets the determination coefficient P W =1,

[0065] The benchmark production speed

[0066] Operation speed V t =P y [P p (V G -V F )+P i ∫(V G -V F )d t ]-V y ;

[0067] Among them, Py It is the on-site commissioning coefficient of the operation and management link, obtained through the inspection, commissioning, comparison and verification of the quality of the finished pipe fittings;

[0068] P p is the first proportional coefficient;

[0069] V G is the benchmark production speed;

[0070] V F The current actual transport speed is obtained by real-time monitoring of the speed sensor;

[0071] P i is the first integral coefficient;

[0072] V y is the mechanical delay coefficient.

[0073] ② When the temperature of the pipe meets the requirements, the temperature meets the determination coefficient P W =0;

[0074] Substituting into the above formula we can get:

[0075] Production benchmark speed V G =0;

[0076] Operation speed V t =0.

[0077] The epoxy powder spraying speed is controlled by a proportional valve, and the proportional valve opening V h By calculation, we can get:

[0078]

[0079] Where V G is the benchmark production speed; P h V is the epoxy spray proportional valve opening adjustment coefficient, which is obtained through inspection, debugging, comparison and verification of the quality of the finished pipe fittings; Nh P is the reference opening of the epoxy spray proportional valve, which is determined by the pipe diameter; NX The current pipe temperature, the adhesion effect of epoxy powder to the pipe wall is affected by temperature, so the opening of the epoxy spray proportional valve is automatically adjusted in real time with the temperature.

[0080] Adhesive extrusion speed V J Calculated by the system, the calculation formula is as follows:

[0081] V J =P J [P PJ (A J V G -V FJ )+P iJ ∫(AJ V G -V FJ )d t ]

[0082] Among them, P J The adhesive extrusion coefficient is obtained through inspection, debugging, comparison and verification of the quality of the finished pipe fittings;

[0083] P pJ is the second proportional coefficient;

[0084] A J It is the speed conversion coefficient, which is set to different values according to the diameter of the pipe fittings and is obtained through the inspection, debugging, comparison and verification of the quality of the finished pipe fittings;

[0085] V FJ It is the actual discharge speed of the adhesive extruder fed back by the sensor.

[0086] P iJ is the second integral coefficient;

[0087] The polyethylene extrusion speed is linearly related to the adhesive extrusion speed:

[0088] V X =2.65V J

[0089] The polyethylene extruder output is fixed at 2.65 times the adhesive output. This coefficient is obtained through inspection, commissioning, comparison, and verification of the quality of the finished pipes.

[0090] After the polyethylene coating spraying process is completed, the pipe must be quickly cooled to the specified temperature. If the water output is insufficient and the pipe is not cooled quickly, it may cause cracks, scratches, bulges, pits, and other problems in the pipe during subsequent processes, resulting in waste. If the water output is too high, it may result in water waste and increase production costs. Therefore, the control of the cooling spray stage is a key control point in the anti-corrosion process.

[0091] The cooling spray water volume is controlled by a proportional valve, and the opening of the proportional valve is related to the temperature of the polyethylene coating on the pipe surface:

[0092] Proportional valve opening V K By calculation, we can get:

[0093]

[0094] Among them, V G is the benchmark production speed;

[0095] P K is the opening adjustment coefficient;

[0096] V NX It is the reference opening, which is determined by the pipe diameter;

[0097] P NX It is the actual temperature of the polyethylene coating fed back by the sensor.

[0098] Based on the above technical solution, the operator inputs the pipe diameter parameters, and the PLC will calculate the equipment action parameters of each link such as heating, pipe transportation, epoxy powder spraying, adhesive extrusion, polyethylene extrusion, cooling spray, etc.

[0099] This embodiment controls each link of the anti-corrosion equipment, so that each link such as heating, pipe transportation, epoxy powder spraying, adhesive extrusion, polyethylene extrusion, and cooling spraying can follow and cooperate with each other through algorithms or closed-loop control, thereby better ensuring product quality, reducing waste output, and saving production costs; the benchmark production speed of the pipe is calculated through the pipe temperature and pipe diameter, and the closed-loop control of the corrosion protection of the transported pipe is completed by calculating the anti-corrosion action parameters, so that the output power of each production link meets the needs of the current actual pipe data, thereby ensuring product quality and avoiding waste output.
