[0045] See also Figure 1 , which is a schematic diagram of a process flow of a cold-rolled ultra-thin wide strip steel bonding control method provided in an embodiment of the present application, which may specifically include:

[0046] S110, obtaining plate parameters of the strip steel, wherein the plate parameters include plate shape and incoming material weight;

[0047] Exemplarily, the plate parameters of the strip steel are obtained, wherein the plate parameters include plate shape and incoming material weight, the target curve of the plate shape is double-sided wave control, and the IU at different positions along the width direction of the strip steel is: IU ≤ 15IU at the edge, ≤ 5IU at the rib, and ≤ 5IU at the middle. The incoming material weight is the weight value of the strip steel plate when it enters a certain production process or is measured.

[0048] S120, when the plate parameters reach preset plate parameters, obtaining process parameters of the bell-type annealing furnace, wherein the process parameters include a preset annealing temperature range and a cooling rate;

[0049] Exemplarily, the acquired plate parameters are compared with the preset plate parameters. If the plate shape meets specific requirements (such as within a certain flatness range) and the incoming material weight is within a preset weight range, it is considered that the plate parameters reach the preset plate parameters. After the plate parameters reach the preset plate parameters, the process parameters of the bell annealing furnace are obtained, wherein the process parameters include the preset range of annealing temperature and cooling rate.

[0050] S130, when the process parameter reaches the preset process parameter, calculating according to the temperature inside the heating hood of the hood-type annealing furnace to obtain a gas flow value;

[0051] Exemplarily, when the process parameters of the bell-type annealing furnace reach the preset process parameters, the gas flow value can be calculated according to the temperature in the heating hood. A temperature sensor is installed in the bell-type annealing furnace to monitor the temperature change in the heating hood in real time. The accuracy and reliability of the temperature sensor are ensured so as to obtain accurate temperature data. The gas supply is adjusted according to the obtained gas flow value so that the temperature in the heating hood is kept within the desired range.

[0052] S140, controlling the bonding of the cold-rolled ultra-thin wide strip steel based on the gas flow value.

[0053] For example, the temperature and gas flow rate in the bell-type annealing furnace are monitored in real time. Temperature sensors and flow meters and other equipment can be used to feed back temperature and flow rate data to the control system. The control system automatically adjusts the gas flow regulating valve according to the preset temperature range and gas flow rate value to maintain a stable annealing temperature.

[0054] In summary, the cold-rolled ultra-thin wide strip steel adhesion control method proposed in the embodiment of the present application improves the adhesion problem of ultra-thin wide strip steel by controlling the plate parameters and the process parameters of the hood annealing furnace.

[0055] In some examples, when the plate parameters reach preset plate parameters, the step of obtaining process parameters of the bell annealing furnace includes:

[0056] When the plate shape is smaller than the preset plate shape and the incoming material weight is smaller than the preset weight, the process parameters of the bell-type annealing furnace are obtained, wherein the preset weight is 12,000 kg.

[0057] Exemplarily, before the strip enters the production process, the shape of the strip is judged. When the shape of the strip is smaller than the preset shape, that is, IU at different positions along the width direction of the strip: IU ≤ 15IU for the edge, ≤ 5IU for the rib, and ≤ 5IU for the middle. Then use a weighing device to weigh the incoming material. Ensure the accuracy and reliability of the weighing equipment so that the weight of the incoming material can be accurately measured. Compare the measured weight of the incoming material with the preset weight (12,000 kg). If the weight of the incoming material is less than the preset weight at this time, obtain the process parameters of the bell annealing furnace.

[0058] In some examples, the step of obtaining process parameters of the bell annealing furnace includes:

[0059] Obtain critical cooling temperature;

[0060] generating a cooling method based on the strip temperature and the critical cooling temperature;

[0061] Obtaining an initial temperature and a final temperature according to the cooling method;

[0062] The cooling rate is obtained by calculation based on the initial temperature and the final temperature.

[0063] For example, a thermal simulation experiment can be conducted, using a thermal dilatometer, a differential thermal analyzer and other equipment to measure the phase change temperature of the steel strip at different cooling rates, thereby determining the critical cooling temperature. The critical cooling temperature can also be predicted based on the chemical composition and initial organizational state of the steel strip using thermodynamic models and phase diagram calculation software. To monitor the temperature of the steel strip in real time, equipment such as thermocouples and infrared thermometers can be used. The temperature of the steel strip is compared with the critical cooling temperature to determine the current cooling mode of the steel strip.

[0064] The critical cooling temperature is defined as Tcritical. When the strip temperature is higher than the critical cooling temperature, the cooling method is hood cooling; when the strip temperature is lower than the critical cooling temperature, the cooling method is air cooling; in order to prevent bonding defects caused by too fast cooling, the critical cooling temperature Tcritical is 450-500℃; the initial temperature and the final temperature are obtained according to the cooling method; the cooling rate is calculated based on the initial temperature and the final temperature. Specifically: the initial temperature of hood cooling is T1, the final temperature is Tcritical, and the cooling rate is 10-30℃ / h. When the strip temperature is lower than Tcritical, air cooling is used. Air cooling is usually a simpler and more economical cooling method, which takes away the heat of the strip through natural convection or forced ventilation. Cooling effect: The cooling rate of air cooling is relatively fast, but the cooling speed can be controlled by adjusting the ventilation intensity and airflow direction. In the stage where the strip temperature is low, water cooling can quickly reduce the strip temperature and improve production efficiency. The initial temperature of air cooling is Tcritical, the final temperature is T3 in the range of 200±20℃, the cooling rate is 30~50℃ / h, the initial temperature of air cooling is T3, the final temperature is T4≤70℃, the cooling rate is 50~80℃ / h. Figure 2 As shown, it is a bell-type furnace annealing curve diagram for preventing the adhesion of ultra-thin wide strip steel in a cold-rolled ultra-thin wide strip steel adhesion control method provided in the present application.

[0065] In some examples, the annealing temperature is preset in a range of 550-700°C.

[0066] For example, the effects of different annealing temperatures and holding times on the bonding and performance of the strip are investigated. Figure 3 As shown, it is a curve diagram of the relationship between annealing temperature and strip bonding and performance in a cold-rolled ultra-thin wide strip bonding control method provided by the present application. The annealing temperature setting range of the hood annealing furnace to prevent bonding is 550-700°C. Annealing within this temperature range can cause recrystallization of the strip, eliminate work hardening, reduce hardness, increase plasticity and toughness, and improve the comprehensive performance of the strip. The corresponding holding time needs to satisfy formula (1).

[0067] t1=0.0145·T1 2 -9.9716·T1+2.724·10 3 (1);

[0068] Wherein, T1 is the annealing temperature setting value, in °C; t1 is the insulation time after heating to the annealing temperature, in min.

[0069] In some examples, when the process parameter reaches the preset process parameter, the step of calculating according to the temperature inside the heating hood of the hood annealing furnace to obtain the gas flow value includes:

[0070] The temperature inside the heating hood is calculated according to the PID control algorithm to obtain the heat load output value;

[0071] Calculating according to the heat load output value to obtain an air flow setting value and an air-fuel ratio setting value;

[0072] The gas flow calculation value is obtained by performing calculation according to the air flow setting value and the air-fuel ratio setting value.

[0073] For example, PID (proportional-integral-differential) control is a commonly used feedback control algorithm for adjusting the output of the system to make it as close to the set value as possible. It performs proportional, integral and differential operations on the error (the difference between the set value and the actual value), and then adds the three operation results to obtain the control output. In a hood annealing furnace, the PID controller calculates the heat load output value based on the error between the actual temperature in the heating hood and the target temperature, calculates based on the heat load output value, and obtains the air flow set value and the air-fuel ratio set value; calculates based on the air flow set value and the air-fuel ratio set value to obtain the gas flow calculated value, so as to adjust the gas flow according to the gas flow calculated value, thereby achieving precise control of the temperature.

[0074] In some examples, the air flow setpoint is expressed as:

[0075]

[0076] Among them, F air is the combustion air flow setting value, k is the power conversion coefficient, r st is the reference air-fuel ratio setting value, I Power is the heat load output value.

[0077] For example, the air flow setting value is related to the heat load output value and the air-fuel ratio setting value. air is the combustion air flow setting value, m 3 / h, k is the power conversion factor, dimensionless, here it is 1.27; rst : Reference air-fuel ratio setting value, dimensionless; I Power is the heat load output value, dimensionless, where dimensionless means no unit.

[0078] In some examples, the air-fuel ratio setting is:

[0079]

[0080] Among them, r sp is the air-fuel ratio setting value, r st is the reference air-fuel ratio setting value, I Power is the heat load output value.

[0081] Exemplarily, the air-fuel ratio setting value is related to the base air-fuel ratio setting value and the heat load output value. sp is the air-fuel ratio setting value, dimensionless. Dimensionless means no unit. The gas flow value is related to the reference air-fuel ratio setting value, the combustion air flow setting value, the system air-fuel ratio setting value and the actual value of the combustion air flow. The calculation method of the gas flow value is shown in formula (4):

[0082] F gas =min(F air / r sp ,F air_pv / r sp )(4);

[0083] I Power The relationship between the combustion air flow, gas flow, and air-fuel ratio system setting value is as follows: Figure 4 As shown, it is a curve diagram showing the relationship between the combustion air and the fuel gas in the combustion system of the bell-type annealing furnace in the method for controlling the adhesion of cold-rolled ultra-thin wide strip steel provided by the present application. It can be seen that in I Power >200, the air-fuel ratio control is normal, and then as I Power The air-fuel ratio is increased as the pressure drops, in order to control sticking.

[0084] The present invention is described in detail below in conjunction with the embodiments, but they should not be construed as limiting the scope of protection of the present invention.

[0085] Example:

Determine the annealing temperature to be 550℃, and calculate the holding time to be 380min according to formula (1). The critical cooling temperature Tcritical is 450℃, which is the end temperature of the hood cooling, and the hood cooling rate is 20℃ / h. The end temperature of air cooling is 200℃, and the cooling rate is 40℃ / h. The end temperature of water cooling is 50℃, and the cooling rate is 60℃ / h.

[0089] Combustion system control: When heating at full speed, I Power =1000, calculate the combustion air flow F air =1270m 3 / h, air-fuel ratio r sp =4.4, gas flow F gas =289m 3 / h. During heat preservation, I Power =400, calculate the combustion air flow F air =508m 3 / h, air-fuel ratio rsp = 4.4, gas flow rate F gas =115m 3 / h. When cooling with hood, I Power =80, calculate the combustion air flow F air =800m 3 / h, air-fuel ratio r sp =18, gas flow F gas =44m 3 / h.

[0090] The annual benefit calculation of ultra-thin wide strip steel is: the average monthly output of ultra-thin wide strip steel × the average monthly benefit difference of tons of steel × 12 = 20 × 5000 × 12 = 1.2 million. Total benefit = 1.2 million yuan.
