DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In the firing process of glazed tiles, heat absorption is a key factor, which is affected by many variables, including firing time, firing temperature, and the size of the firing room. The interaction of these factors makes the heat absorption process of glazed tiles complicated, which in turn affects the strength and quality of the final product. Therefore, when controlling the firing production line based on the strength analysis results of the finished glaze, there are many challenges. First, firing time and temperature are the main factors affecting the quality of glazed tiles. Too long or too short firing time, as well as improper temperature control, will lead to insufficient or excessive strength of glazed tiles, thus affecting their performance. In addition, the size of the firing room will also have a significant impact on the distribution and absorption of heat. In a small firing room, heat may be concentrated, causing some bricks to overheat, while in a larger firing room, heat distribution may be uneven, resulting in some products failing to achieve the ideal firing effect. Secondly, due to the involvement of multiple variable factors, the control of the firing production line becomes complex and difficult. In order to ensure the quality of glazed tiles, the adjustment of the production line needs to take into account changes in multiple aspects. However, it is this diversity that makes the location of the problem not quick and accurate enough. Production managers often find it difficult to identify the specific factors that affect the quality of the finished product in the first time, which leads to a decrease in the efficiency of the entire production process. Therefore, when controlling the production line based on the strength analysis results of the glazed tiles, it will be impossible to quickly locate the specific problem points in the production line due to the existence of multiple uncertain factors, resulting in the inability to quickly control the firing production line. The technical solution provided by the present application, in the process of firing the glazed tiles, by obtaining the heat absorbed by the glazed tiles during the firing process The amount of heat actually absorbed by the target glazed tile is obtained, and the analysis result item is obtained according to the glaze strength analysis result of the glazed tile. The difference between the analysis result item and the target strength is used as the target difference. The heat data corresponding to the analysis result item is the corresponding heat data. The corresponding heat data is percentileized, and the target heat data is obtained according to the target difference. According to the target heat data and the above heat formula, some variables are adjusted to quickly locate the target variable, and the production line is adjusted according to the target variable. Since there are multiple target variables, corresponding adjustments can be made according to different production line conditions, making the adjustment of the production line more intelligent. Specifically, in this application, Figure 1 As shown, steps S100-S400 are included.

[0021] Step S100: obtaining data on the amount of heat absorbed by the glazed tiles during the firing process.

[0022] It should be noted that the heat absorbed by the glazed tiles during the firing process is related to data such as the firing temperature and firing time. Therefore, it is necessary to obtain the actual heat absorption data of the target glazed tiles during the actual firing process.

[0023] Specifically, the method for acquiring the absorbed heat data in step S100 includes steps S101-S104.

[0024] Step S101: Obtain basic information.

[0025] It should be noted that the basic information includes the volume data of the firing room used to fire glazed tiles in the production line. The production line will be set with identification data information, including the maximum power of the firing room, the volume of the firing room and other basic information. Therefore, the volume data of the firing room can be obtained through the identification data information set on the production line.

[0026] Step S102: Obtaining material information.

[0027] It should be noted that in the process of firing glazed tiles, the actual material information of glazed tiles of different materials is different, including the thermal conductivity coefficient, density and specific heat capacity of the target glazed tiles. Information is obtained based on big data, and the required material information is obtained from big data according to the material information of the specific glazed tiles being fired.

[0028] Step S103: Acquisition of characteristic information.

[0029] It should be noted that the characteristic information represents various data of the fired glazed tiles, which need to be detected and acquired, including the length, width and height data of the fired glazed tiles, so as to obtain the thickness data and volume data of the glazed tiles.

[0030] Before firing the glazed tiles, the length, width and height of the glazed tiles are detected by means of a laser rangefinder or other device. The volume data of the glazed tiles are calculated based on the detected data, and the height data of the glazed tiles are used as the thickness data of the glazed tiles.

[0031] It should be noted that, in addition to the data of the glazed tiles, the characteristic information also needs to obtain the initial temperature of the firing room, and the method for obtaining the initial temperature includes S1031-S1033.

[0032] Step S1031: Layout setting.

[0033] Based on the acquired volume data of the firing room, the spacing item and the arrangement item are set, wherein the spacing item is height data and the arrangement item is specific quantity data. The spacing item is set to 25% and the arrangement item is set to 5.

[0034] like Figure 2-Figure 3 As shown, step S1032: feature point setting, based on the interval item and the arrangement item, take the arrangement item as the basis, arrange the target number of measurement points as the first batch of feature points, take the interval item as the cutting point, rearrange the target number of measurement points as the second batch of feature points, repeat the above steps to obtain a feature point set.

[0035] like Figure 4 As shown, in the specific implementation process, it is learned that the volume data of the firing room is 1m³, wherein the length, width and height of the firing room are all 1m. According to the set interval items and layout items, 5 measuring points are arranged at heights of 25cm, 50cm, 75cm and 100cm in the firing room as cutting points, respectively. The number of measuring points is 20 in total, wherein the horizontal plane with a height of 25cm in the firing room is the first horizontal plane, and the five arranged measuring points are the first batch of feature points; the horizontal plane with a height of 50cm in the firing room is the second horizontal plane, and the five arranged measuring points are the second batch of feature points; the horizontal plane with a height of 75cm in the firing room is the third horizontal plane, and the five arranged measuring points are the third batch of feature points; the horizontal plane with a height of 100cm in the firing room is the fourth horizontal plane, and the five arranged measuring points are the fourth batch of feature points.

[0036] Step S1033: temperature measurement, based on the set 20 measurement points, temperature measurements are performed respectively. The temperature of the measurement points can be measured by temperature measuring equipment, such as a temperature measuring instrument, at each measurement point, and the average temperature in the entire firing room is obtained based on the measured temperature to obtain the initial temperature information.

[0037] In the specific implementation process, the horizontal plane with a height of 25 cm in the firing room is the first horizontal plane, the five measurement points arranged are the first batch of characteristic points, and the measured temperature data are 295K, 301K, 303K, 290K, and 305K respectively. The horizontal plane with a height of 50 cm in the firing room is the second horizontal plane, the five measurement points arranged are the second batch of characteristic points, and the measured temperature data are 299K, 290K, 304K, 296K, and 297K respectively. The horizontal plane with a height of 75 cm in the firing room is the second horizontal plane, the five measurement points arranged are the second batch of characteristic points, and the measured temperature data are 299K, 290K, 304K, 296K, and 297K respectively. The horizontal plane with a height of 100 cm in the firing room is the fourth horizontal plane, and the five measurement points arranged are the third batch of feature points. The measured temperature data are 300K, 298K, 306K, 291K, and 294K, respectively. The horizontal plane with a height of 100 cm in the firing room is the fourth horizontal plane, and the five measurement points arranged are the fourth batch of feature points. The measured temperature data are 293K, 301K, 308K, 297K, and 292K, respectively. At this time, the average temperature data obtained from each measurement point is 298K, that is, the initial temperature information is 298K.

[0038] Step S104: Acquisition of heat data.

[0039] According to the set heat absorption formula: ,in is the amount of heat absorbed, is the thermal conductivity of the material, is the volume of the firing room, It is the firing time. is the firing temperature, is the initial temperature, is the thickness of the glazed tile, is the volume of the glazed tile, is the reference volume, is the density of the material, is the specific heat capacity of the material.

[0040] In the specific implementation process, the firing temperature is obtained according to the set information. =1200K, initial temperature 298K, firing time For 1h, the thickness of glazed tiles 0.01m, glazed tile length 0.2m, glazed tile width 0.2m, firing room volume For 1m³, the thermal conductivity is 1.5J / m, the density of the material is 2500kg / m³, and the specific heat capacity of the material is 800J / kg, the volume of the glazed tile is V=0.0004m³, and the formula is: The calculated heat absorbed is 108240000.

[0041] Step S200: Detect and analyze the strength of the glazed tiles using a detection method.

[0042] It should be noted that the detection direction is to test the wear resistance of the glazed tiles. Therefore, the detection method adopted is to use the wear medium to perform rotational friction on the top of the finished glazed tiles. When obvious damage is observed on the finished glazed tiles, the number of circles of the wear medium rotating on the top of the glazed tiles is obtained to calculate the amount of wear on the glazed tiles.

[0043] Set the wear formula: ,in is the amount of wear, is the wear coefficient, a constant related to material properties and test conditions, is the diameter of the wear medium, is the amount of wear medium, is the speed of the wear medium moving, The number of circles drawn for the wear medium is based on the wear amount as the detection result to obtain the analysis result item.

[0044] In the specific implementation process, a wear medium steel ball with a diameter of 10 mm is used, the mass N of the wear medium steel ball is 5, the speed of the wear medium movement is 50 mm / s, the number of circles drawn by the wear medium is 20, and the wear coefficient is set to 0.02. After calculation, it is found that the wear amount of the target glazed tile is 10000.

[0045] Step S300: Obtain the difference between the analysis result item and the target strength index.

[0046] It should be noted that the target strength index is a fixed value, which is the minimum wear amount that glazed tiles that meet the minimum standard requirements can withstand without causing obvious damage. The minimum standard is 40 laps. After calculation by the wear formula, the wear amount corresponding to the minimum standard is 20,000. At this time, the target difference item is 10,000. , the calculated difference heat item is 108240000.

[0047] Step S400: Reversely locate the variable based on the target heat item.

[0048] It should be noted that since the thermal conductivity of the material, the thickness of the glazed tile, the volume of the glazed tile, the reference volume, the density of the material and the specific heat capacity of the material are all fixed values ​​in the calculation formula of the heat data, the variable variables are the volume between firings, the firing time, the firing temperature and the initial temperature. Since the difference heat item is 108240000, it is achieved by adjusting the volume between firings, the firing time, the firing temperature and the initial temperature. =216480000.

[0049] In the specific implementation process, according to the heat absorption formula , the thickness of the glazed tile is 0.01m, the length of the glazed tile is 0.2m, the width of the glazed tile is 0.2m, the volume of the firing room is 1m³, the thermal conductivity is 1.5J / m, the density of the material is 2500kg / m³, the specific heat capacity of the material is 800J / kg, the volume of the glazed tile is 0.0004m³, and the heat data absorbed by adjusting the volume of the firing room, the firing time, the firing temperature and the initial temperature is 216480000. The combination result can be:

[0050] Result 1: Adjust the volume of the firing room.

[0051] The thickness of the glazed tile is 0.01m, the length of the glazed tile is 0.2m, the width of the glazed tile is 0.2m, the volume of the firing room is 1m³, the thermal conductivity is 1.5J / m, the density of the material is 2500kg / m³, the specific heat capacity of the material is 800J / kg, the volume of the glazed tile is 0.0004m³, the firing time is 1h, the firing temperature is 1200K, the initial temperature is 298K, and the heat data absorbed by adjusting the volume of the firing room is 216480000. Through the formula , , the volume A of the firing room is calculated to be 2m³, that is, on the basis of other conditions remaining unchanged, by replacing the firing room, the volume of the firing room is made to 2m³, the heat data absorbed by the glazed tiles can be made to be 216480000, thereby meeting the target heat item, and then the production line is controlled based on the adjustment amount of the target variable item, that is, the control method of the production line is to adjust the volume of the firing room.

[0053] The thickness of the glazed tile is 0.01m, the length of the glazed tile is 0.2m, the width of the glazed tile is 0.2m, the volume of the firing room is 1m³, the thermal conductivity is 1.5J / m, the density of the material is 2500kg / m³, the specific heat capacity of the material is 800J / kg, the volume of the glazed tile is 0.0004m³, the volume of the firing room is 1m³, the firing temperature is 1200K, the initial temperature is 298K, and the heat data absorbed by adjusting the volume of the firing room is 216480000. Through the formula , , the firing time is calculated to be 2h, that is, on the basis of other conditions remaining unchanged, by adjusting the firing time to 2h, the heat data absorbed by the glazed tiles can be made 216480000, thereby meeting the target heat item, and then the production line is controlled based on the adjustment amount of the target variable item, that is, the control method of the production line is to adjust the firing time.

[0054] Result 3: Adjust the initial temperature.

[0055] The thickness of the glazed tile is 0.01m, the length of the glazed tile is 0.2m, the width of the glazed tile is 0.2m, the volume of the firing room is 1m³, the thermal conductivity is 1.5J / m, the density of the material is 2500kg / m³, the specific heat capacity of the material is 800J / kg, the volume of the glazed tile is 0.0004m³, the volume of the firing room is 1m³, the firing temperature is 1200K, and the firing time is 1h. By adjusting the volume of the firing room to meet the absorbed heat data of 216480000, through the formula , , The initial temperature is calculated to be -604, that is, on the basis of other conditions remaining unchanged, by adjusting the initial temperature to -604, the heat data absorbed by the glazed tiles can be made 216480000, thereby meeting the target heat item, and then the production line is controlled based on the adjustment amount of the target variable item, that is, the control method for the production line is to adjust the initial temperature.

[0056] Since the initial temperature cannot be a negative number, result 3 is obviously unachievable, which means that the heat data of 216480000 cannot be satisfied simply by adjusting the initial temperature while keeping other data unchanged.

[0057] Result 4: Adjust the firing temperature.

[0058] The thickness of the glazed tile is 0.01m, the length of the glazed tile is 0.2m, the width of the glazed tile is 0.2m, the volume of the firing room is 1m³, the thermal conductivity is 1.5J / m, the density of the material is 2500kg / m³, the specific heat capacity of the material is 800J / kg, the volume of the glazed tile is 0.0004m³, the firing time is 1h, the volume of the firing room is 1m³, the initial temperature is 298K, and the heat data absorbed by adjusting the volume of the firing room is 216480000. Through the formula , , The firing temperature is calculated to be 2102K, that is, on the basis of other conditions remaining unchanged, by adjusting the firing temperature to 2102K, the heat data absorbed by the glazed tiles can be made to be 216480000, thereby meeting the target heat item, and then the production line is controlled based on the adjustment amount of the target variable item, that is, the control method of the production line is to adjust the firing temperature.

By simultaneously adjusting the volume of the firing room, firing time, firing temperature and initial temperature, the absorbed heat data is 216480000.

[0061] Example 1: The thickness of the glazed tile is 0.01m, the length of the glazed tile is 0.2m, the width of the glazed tile is 0.2m, the volume of the firing room is 1m³, the thermal conductivity is 1.5J / m, the density of the material is 2500kg / m³, the specific heat capacity of the material is 800J / kg, the volume of the glazed tile is 0.0004m³, the volume of the firing room remains unchanged, still 1m³, the firing time is 1.5h, the initial temperature remains unchanged, which is 298K, and the heat data required to be absorbed is 216480000. According to , , After calculation, it is found that the firing temperature is 1500.67K, so the production line is adjusted by adjusting the firing time and the firing temperature. The firing time is increased from 1h to 1.5h, and the firing temperature is increased from 1200k to 1500.67K. This adjustment method is suitable for situations where the scale of the production line is not easy to adjust, such as when the specifications of the firing room are fixed, but the firing temperature and firing time can be adjusted.

[0062] Example 2: The thickness of the glazed tile is 0.01m, the length of the glazed tile is 0.2m, the width of the glazed tile is 0.2m, the volume of the firing room is 1m³, the thermal conductivity is 1.5J / m, the density of the material is 2500kg / m³, the specific heat capacity of the material is 800J / kg, the volume of the glazed tile is 0.0004m³, the volume of the firing room becomes 1.5m³, the firing time is 1.3h, the initial temperature remains unchanged at 298K, and the heat data required to be absorbed is 216480000. According to , , After calculation, it is found that the firing temperature is 1223.12K. Therefore, the production line is adjusted by adjusting the firing time, adjusting the firing temperature and replacing the firing room. The firing time is increased from 1h to 1.3h, the firing temperature is increased from 1200k to 1223.12K, and the volume of the firing room is changed from 1m³ to 1.5m³. This adjustment method is suitable for production lines with firing rooms of various sizes, but the firing time and firing temperature can be flexibly changed.

[0063] Example 3: The thickness of the glazed tile is 0.01m, the length of the glazed tile is 0.2m, the width of the glazed tile is 0.2m, the volume of the firing room is 1m³, the thermal conductivity is 1.5J / m, the density of the material is 2500kg / m³, the specific heat capacity of the material is 800J / kg, the volume of the glazed tile is 0.0004m³, the volume of the firing room becomes 1.6m³, the firing time is 0.6h, the initial temperature remains unchanged at 298K, and the heat data required to be absorbed is 216480000. According to , , After calculation, it is found that the firing temperature is 1965.80K, so the production line is adjusted by adjusting the firing time, adjusting the firing temperature and replacing the firing room. The firing time is reduced from 1h to 0.6h, the firing temperature is increased from 1200k to 1965.80K, and the volume of the firing room is changed from 1m³ to 1.6m³. This adjustment method is suitable for production lines with firing rooms of various sizes. Firing rooms of various specifications can be used, but the firing time needs to be saved. Therefore, the production line needs to have high-strength firing equipment that can meet the firing temperature of 1965.80K.

The volume data of the glazed tiles is calculated based on the detected data, and the height data of the glazed tiles is used as the thickness data of the glazed tiles. The average temperature in the entire firing room is acquired, and the heat data absorbed by the glazed tiles during the firing process is calculated using the heat absorption formula; Detection module: The strength of the glazed tiles is detected and analyzed through detection methods. In the specific implementation process, the wear resistance of the glazed tiles is detected. Therefore, the detection method used is to use the wear medium to perform rotational friction on the top of the finished glazed tiles. When the finished glazed tiles are observed to be obviously damaged, the number of rotations of the wear medium on the top of the glazed tiles is obtained to calculate the amount of wear on the glazed tiles; Processing module: According to the glaze strength analysis results of glazed tiles, the difference between the analysis results and the target strength is used as the target difference, the heat data corresponding to the analysis result item is the corresponding heat data, and the target heat data is obtained according to the target difference. According to the target heat data and the heat formula, some variables are adjusted to quickly locate the target variables, and the production line is adjusted according to the target variables.
