[0064] like Figure 1 As shown, an embodiment of the present invention provides a method for controlling the temperature of an insulator sintering furnace, comprising the following steps:

[0065] S1: Generate a preset temperature control plan;

[0066] Among them, the preset temperature control scheme is a sintering furnace initialization configuration scheme customized based on the insulator firing requirements;

[0067] Specifically, the firing target requirements of the insulator to be sintered are analyzed in detail, and corresponding program parameters are set on the sintering furnace based on the firing target requirements.

[0068] S2: Monitor the real-time heating data of each area in the sintering furnace and determine the real-time temperature rise data of the insulators in each area based on the real-time heating data;

[0069] Real-time heating data refers to the real-time heating data of the insulator in the sintering furnace;

[0070] The inner cavity of the sintering furnace is divided into several areas based on the position of the insulator in the sintering furnace during firing;

[0071] Collect real-time temperature data from each area, generate a scatter plot of the real-time temperature data from each area based on the time series, and generate a three-point spline curve;

[0072] Determine the temperature rise data of each region based on the spline curve;

[0073] The heating data includes heating time and heating efficiency of each area.

[0074] It should be noted that the spline curve is within the spline curve graph, the X-axis in the spline curve graph represents time, and the Y-axis represents regional temperature.

[0075] Specifically, by analyzing and collecting real-time heating data from various areas within the sintering furnace, the temperature changes in various areas within the sintering furnace as the insulator executes the sintering program can be determined, providing a reference for subsequent temperature adjustments.

[0076] S3: Analyze the first abnormal temperature value in the temperature time series of the first region in the real-time heating data to obtain a first predicted sintering quality;

[0077] Specifically, we select a zone as the insulator's sintering location (denoted as the first zone). Each sintering zone within the sintering furnace significantly impacts insulator quality. By collecting and analyzing real-time temperature data from the first zone, we can determine the temperature variation pattern within that zone and the final sintering results of the insulator under this temperature variation pattern. Based on the results of the temperature time series analysis, we use a mathematical model to predict the final sintering result and the first predicted sintering quality.

[0078] S4: performing simulation based on the first abnormal temperature value, thereby generating simulation data of the first abnormal temperature value;

[0079] It should be noted that the simulation of the first abnormal temperature value requires the use of a simulation control center. The simulation control center uses virtual simulation technology to simulate the sintering process of the insulator in the sintering furnace and calculate the dimensions and mass of the insulator at this abnormal temperature value. The simulation results are used to determine whether the sintering furnace's temperature control is normal, that is, whether the abnormal temperature value will cause quality problems in the insulator.

[0080] Specifically, the first abnormal temperature value is rendered into a simulation model of the insulator blank to perform simulation calculation to obtain first simulation information;

[0081] The simulation information includes sintering result information such as insulator quality and appearance.

[0082] The insulator data in the first simulation information is extracted and compared with the data of the target insulator, and the comparison result is used as the simulation data.

[0083] S5: Analyze and judge the simulation data to obtain a first judgment result of the first region at the first moment;

[0084] Specifically, the insulator parameters in the first simulation information are compared with the parameters of the target insulator.

[0085] It is understood that the comparison process combines the allowable error range to determine whether the simulated insulator parameters are within the preset range. Based on the comparison results, it is determined whether the stamping effect of the stamping equipment under the predicted pressure value meets the manufacturing requirements. If the simulated parameters differ significantly from the target parameters or exceed the allowable error range, it is considered that there is an abnormality in the temperature control of the sintering furnace.

[0086] S6: Adjusting the preset temperature control scheme from the first moment based on the first judgment result.

[0087] Specifically, after analyzing the first judgment result, the parameters of the preset temperature control scheme are automatically adjusted according to the content of the first judgment result (the size of the temperature deviation in the sintering furnace and the temperature change rate), and the adjusted temperature control scheme is executed in the sintering furnace, so that the sintering result of the insulator can meet the expectations.

[0088] Step S6 further includes step S61: analyzing the first judgment result to determine a deviation between the temperature at the first moment and the preset temperature. Specifically, the temperature of the first area at the first moment can be determined based on the data in the first judgment result, thereby obtaining the deviation between the temperature of the first area at the first moment and the preset temperature.

[0089] S62: Calculate a temperature correction at a subsequent first moment based on the deviation value, and the effect of the correction on the temperatures of adjacent regions of the first region. Specifically, due to internal interconnectedness within the sintering furnace, a temperature change in one region may also affect the temperatures of adjacent regions. The temperature correction and its effect on the temperatures of adjacent regions of the first region can be used to determine the effect of introducing the temperature correction on the sintering quality of insulators within the regions associated with the first region.

[0090] S63: Determine a final temperature correction amount and a duration for the temperature correction based on the temperature correction amount and its effect on the temperature of the areas adjacent to the first area. Specifically, the effect of the correction amount on the temperature of the areas adjacent to the first area is used to determine whether this effect will affect the sintering quality of insulators in the areas adjacent to the first area. If so, the effect on the temperature of the areas adjacent to the first area is reduced by extending the correction duration of the temperature correction amount.

[0091] It is understandable that by setting a threshold for temperature deviation in the sintering furnace and analyzing the impact of the temperature correction on the temperature of the adjacent areas of the first area, if the value is within the threshold, it means that when the temperature of the first area is adjusted, there is no impact on the surrounding areas.

[0092] S64: The determined final temperature correction amount and the duration of the temperature correction are configured into the preset temperature control plan and executed on the sintering furnace. Specifically, the parameters of the preset temperature control plan are adjusted according to the determined final temperature correction amount and the duration of the temperature correction. After the adjustment is completed, the new temperature control plan is applied to the sintering furnace and the effect after application is monitored. If the sintering efficiency is improved and meets the target sintering requirements, it means that the adjustment is effective; if there are still problems, further analysis and adjustment are required. In this way, the control system can adjust and optimize the pressure control plan before the sintering process is affected, thereby avoiding the situation in which the abnormal temperature at a certain moment in the actual sintering process cannot accurately judge the subsequent sintering quality.

[0093] It is understandable that the preset temperature control scheme will be adjusted only when the first judgment result indicates that there is an abnormality in the temperature control of the sintering furnace.

[0094] In this embodiment, the process of calculating the temperature correction amount at the subsequent first moment and the influence of the correction amount on the temperature of the adjacent area of the first area based on the deviation value includes:

[0095] Determine the temperature compensation amount based on the deviation value and the real-time temperature rise data of the regional insulators;

[0096] determining, by the temperature compensation amount, the effect of the temperature compensation amount on the temperature of the region adjacent to the first region;

[0097] The formula for the impact is:

[0098] ;

[0099] in, represents the temperature change in region i+1, represents the thermal power variation of region i, L represents the thickness of the furnace wall shared between adjacent regions i and i+1, k represents the thermal conductivity of the furnace wall, represents the Stefan-Boltzmann constant, represents the emissivity of the furnace wall surface, represents the average temperature of regions i and i+1, and A represents the contact area between adjacent regions i and i+1.

[0100] The insulator sintering furnace temperature control method provided in this embodiment generates a preset temperature control scheme; monitors the real-time heating data of each area in the sintering furnace, and determines the real-time temperature rise data of the insulators in each area based on the real-time heating data; analyzes the first abnormal temperature value under the temperature time series of the first area in the real-time heating data to obtain a first predicted sintering quality; performs simulation based on the first abnormal temperature value, thereby generating simulation data of the first abnormal temperature value; analyzes and judges the simulation data to obtain a first judgment result of the first area at the first moment; and adjusts the preset temperature control scheme from the first moment based on the first judgment result. The present invention can respond to the abnormal temperature of a certain area in the sintering furnace in a timely manner as a temperature control, thereby achieving the technical effect of realizing high-precision temperature control and ensuring excellent sintering yield of the insulator. At the same time, when performing temperature control on a single sintering area, the temperature influence on the adjacent areas of the adjustment area is reduced, thereby ensuring the temperature control accuracy of the sintering area of the sintering furnace.
