[0052] Many specific details are set forth in the following description in order to provide a thorough understanding of this specification. However, this specification can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the connotation of this specification. Therefore, this specification is not limited by the specific implementations disclosed below.

[0054] It should be understood that although the terms first, second, etc. may be used in one or more embodiments of this specification to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of one or more embodiments of this specification, the first may also be referred to as the second, and similarly, the second may also be referred to as the first. Depending on the context, the word "if" as used herein may be interpreted as "when" or "while" or "in response to determining".
[0055] In this specification, an evaluation method for the furnace type state is provided. This specification is also related to an evaluation device for the furnace type state, a computing device, and a computer-readable storage medium, which will be described in detail one by one in the following embodiments.
[0056] Figure 1 A flow chart of an evaluation method for a furnace type state provided for an embodiment of this specification, as Figure 1 shown, the method includes:
[0057] Step 101: Based on the historical slag skin thickness profile reference data, the computing device determines the target historical slag skin thickness profile reference data and the target reference mapping degree value corresponding to the blast furnace section angle slag skin value according to the blast furnace section angle slag skin value. The blast furnace section angle slag skin value is the slag skin value of the blast furnace section at a preset angle.
[0058] In some embodiments, the computing device includes, but is not limited to, mobile phones, servers, laptop computers, desktop computers, wearable devices, etc. The blast furnace can be pre-divided into n sections, and the blast furnace section can be one of the n blast furnace sections; each blast furnace section can be further divided into m angles to achieve multi-section and multi-angle data collection and analysis of the blast furnace, where n is an integer greater than or equal to 1, and m is an integer greater than or equal to 1.
[0059] For example, Figure 2 FIG. is a schematic diagram of a blast furnace section provided in an embodiment of this specification, as Figure 2 shown, the blast furnace is divided into 3 sections, from top to bottom are the furnace shaft , the furnace waist and the hearth , and each blast furnace section is further divided into 4 angles, from left to right are the first angle , the second angle , the third angle and the fourth angle . The computing device first generates the blast furnace section angle slag skin values corresponding to different angles of each blast furnace section according to the different angles of the blast furnace section, so as to generate , , …, respectively corresponding blast furnace section angle slag skin values.
[0060] The target historical slag skin thickness profile reference data is the historical slag skin thickness profile reference data that is most similar to the mapping degree of the blast furnace section angle slag skin value. The target reference mapping degree value is the value of the mapping degree between the blast furnace section angle slag skin value and the target historical slag skin thickness profile reference data. As Figure 2 shown, the , , …, respectively corresponding target reference mapping degree values are obtained.
[0061] Step 102: The computing device generates a reference mapping degree mean value based on the target reference mapping degree value.
[0062] In some embodiments, as Figure 2 shown, the computing device will perform a mean value operation on the , , …, respectively corresponding target reference mapping degree values to obtain the reference mapping degree mean value.
[0063] Alternatively, when the number of target reference mapping degree values is 1, use the target reference mapping degree value as the reference mapping degree average value.
[0064] Step 103: When the computing device determines that the reference mapping degree average value is within the mapping standard threshold range, based on the correspondence between the target historical slag skin thickness profile reference data and the furnace type grade, determine the blast furnace section angle furnace type grade corresponding to the blast furnace section angle slag skin value.
[0065] In some embodiments, set the mapping standard threshold range according to blast furnace experience. For example, set the mapping threshold according to blast furnace experience, and use the range greater than or equal to the mapping threshold as the mapping standard threshold range. When the reference mapping degree average value is within the range greater than or equal to the mapping threshold, it indicates that the reference mapping degree average value is within the mapping standard threshold range. At the same time, the reference mapping degree average value also reflects a relatively high mapping degree between the blast furnace section angle slag skin value and the target historical slag skin thickness profile reference data.
[0066] Based on the correspondence between the historical slag skin thickness profile reference data and the furnace type grade, as well as the correspondence between the blast furnace section angle slag skin value and the target historical slag skin thickness profile reference data, the computing device uses the furnace type grade corresponding to the target historical slag skin thickness profile reference data as the blast furnace section angle furnace type grade corresponding to the blast furnace section angle slag skin value.
[0067] The blast furnace section angle furnace type grade includes grade 1, grade 2, or grade 3. The higher the blast furnace section angle furnace type grade, the better the furnace type state; alternatively, the blast furnace section angle furnace type grade includes excellent grade, general grade, or poor grade. This embodiment does not limit the furnace type grade.
[0068] Step 104: The computing device generates a full-angle operation furnace type activity index based on the blast furnace section angle furnace type grade.
[0069] In some embodiments, the computing device obtains at least one blast furnace section angle furnace type grade based on at least one angle of at least one blast furnace section, and then combines the angle activity to set the weight factor for each angle to obtain the full-angle operation furnace type activity index.
[0070] Step 105: The computing device generates a full-angle furnace type state based on the full-angle operation furnace type activity index.
[0071] In some embodiments, the computing device can pre-divide the boundaries of the full-angle operation furnace type activity index and formulate corresponding state rules. For example, the full-angle furnace type state includes excellent state, general state, or poor state, etc.
[0072] Step 106: The computing device generates an operation furnace type state evaluation result based on the full-angle furnace type state and the blast furnace section angle furnace type grade.
[0073] In some embodiments, the computing device modifies the full-angle furnace profile state based on blast furnace experience and with reference to the blast furnace section angle furnace profile level, making the modified full-angle furnace profile state more in line with the actual state. The operating furnace profile state evaluation result includes the modified full-angle furnace profile state. The operating furnace profile state evaluation result may also include at least one of the blast furnace section angle furnace profile level, the full-angle furnace profile state, the full-angle operating furnace profile activity index, and the blast furnace section angle slag skin value.
[0074] An embodiment of this specification provides a method for evaluating a furnace profile state. Based on historical slag skin thickness profile reference data, according to the blast furnace section angle slag skin value, the target historical slag skin thickness profile reference data and the target reference mapping degree value corresponding to the blast furnace section angle slag skin value are determined. The blast furnace section angle slag skin value is the slag skin value of the blast furnace section at a preset angle; a reference mapping degree average value is generated based on the target reference mapping degree value; based on the reference mapping degree average value being within the mapping standard threshold range, according to the correspondence between the target historical slag skin thickness profile reference data and the furnace profile level, the blast furnace section angle furnace profile level corresponding to the blast furnace section angle slag skin value is determined; based on the blast furnace section angle furnace profile level, a full-angle operating furnace profile activity index is generated; based on the full-angle operating furnace profile activity index, a full-angle furnace profile state is generated; based on the full-angle furnace profile state and the blast furnace section angle furnace profile level, an operating furnace profile state evaluation result is generated. Thus, based on actual blast furnace data, without the need to add auxiliary equipment and without other cost burdens, according to the blast furnace section angle slag skin value collected in real time, by making a similarity match with the historical slag skin thickness profile reference data, the reference mapping degree average value is obtained; when the reference mapping degree average value is within the mapping standard threshold range, the target reference mapping degree value between the blast furnace section angle slag skin value and the historical slag skin thickness profile reference data is relatively high, and then the blast furnace section angle furnace profile level is determined, and then the full-angle furnace profile state is obtained. Based on the blast furnace section angle furnace profile level, the full-angle furnace profile state is further modified to obtain the final operating furnace profile state evaluation result. The evaluation result is accurate, conforms to the actual situation, has strong adaptability and interpretability, and can effectively assist operators in controlling the operating furnace profile state of the blast furnace and improving the stable and smooth operation level of the blast furnace.
[0075] In this specification, Figure 2 This is only an example of the blast furnace sections divided by the blast furnace and the angles divided by the blast furnace sections, and does not limit the number of sections and the number of angles divided by the blast furnace. For example, the blast furnace can also be divided into 5 sections, and the angles can be divided into 2, etc., which will not be listed one by one here. The number of sections and the number of angles divided by the blast furnace can be arbitrarily matched according to settings, actual needs, etc., and there is no proportional limit on the number of sections and the number of angles divided by the blast furnace.
[0076] In a possible implementation manner, before step 103, it further includes: step 1001, the computing device generates key parameters of the furnace profile state based on historical slag skin data and smelting data.
[0077] In some embodiments, the slag crust refers to the layer of slag adhering to the furnace wall, and the condensates in the high heat load area and the low heat load area can be collectively referred to as the slag crust. The computing device collects the historical data of the slag crust thickness at different heights and angles of the blast furnace as the historical slag crust data, and also collects data such as the historical operation data, the historical status data, the historical economic index data, and the slag-iron quality data of the blast furnace as the smelting data.
[0078] The computing device performs data standardization processing on the historical slag crust data and the smelting data to generate historical slag crust standard data and smelting standard data; based on the historical slag crust standard data and the smelting standard data, key parameters of the furnace shape state are generated.
[0079] The computing device integrates the historical slag crust data and the smelting data based on the time series, and applies methods such as blast furnace experience and interpolation method to process the data for abnormal phenomena such as inconsistent data frequencies, outliers, and missing values, to obtain the historical slag crust standard data and the smelting standard data.
[0080] The key parameters of the furnace shape state include at least one of the parameters such as hot metal quality, slag quality, gas utilization rate, fuel ratio, slag crust stability index, and slag crust uniformity index.
[0081] Step 1002: The computing device generates grid interval values of the key parameters based on the key parameters of the furnace shape state.
[0082] In some embodiments, the computing device determines the grid interval values of the key parameters corresponding to the furnace shape state based on the grid interval range corresponding to the key parameters of the furnace shape state.
[0083] When the key parameters of the furnace shape state include parameters such as hot metal quality, slag quality, gas utilization rate, fuel ratio, slag crust stability index, and slag crust uniformity index, the computing device grids the parameters of hot metal quality, slag quality, gas utilization rate, fuel ratio, slag crust stability index, and slag crust uniformity index respectively to obtain grid interval values of hot metal quality, grid interval values of slag quality, grid interval values of gas utilization rate, grid interval values of fuel ratio, grid interval values of slag crust stability index, grid interval values of slag crust uniformity index, etc. For example, the hot metal quality corresponds to 3 grid interval ranges of hot metal quality, and the grid interval values corresponding to the grid interval ranges of hot metal quality are 1, 2, or 3; the computing device determines the grid interval values of hot metal quality based on the grid interval range of hot metal quality corresponding to the hot metal quality and the grid interval values corresponding to the grid interval range of hot metal quality.
[0084] Step 1003: The computing device determines the furnace type grade based on the grid interval values of the key parameters through blast furnace experience.
[0085] In some embodiments, based on blast furnace experience, a general rule for the universality level of the operating furnace profile is established. The calculation device determines the furnace profile level corresponding to the key parameter grid interval value through fuzzy matching according to the general rule for the universality level of the operating furnace profile.
[0086] For example, when the molten iron quality interval is 2, the slag quality interval is 2, the gas utilization rate interval is 2, the fuel ratio interval is 2, the slag skin stability index interval is 2, and the slag skin uniformity index interval is 2, the calculation device determines that the operating furnace profile status level is level 2 according to the general rule for the universality level of the operating furnace profile through fuzzy matching. When the data is in the molten iron quality interval 3, the slag quality interval 3, the gas utilization rate interval 3, the fuel ratio interval 3, the slag skin stability index interval 3, and the slag skin uniformity index interval 3, the calculation device determines that the operating furnace profile status level is level 3 according to the general rule for the universality level of the operating furnace profile through fuzzy matching.
[0087] Step 1004: The calculation device divides the historical slag skin data based on the divided blast furnace angle segments through a statistical method to generate the preset height slag skin mean value corresponding to the blast furnace angle segments.
[0088] In some embodiments, the blast furnace sections and the angles of the blast furnace sections are pre-divided. The historical slag skin data is divided based on different heights of each angle to obtain the historical slag skin height data. The mean value operation is performed on the historical slag skin height data at the same height of different angles to obtain the preset height slag skin mean value at different heights.
[0089] Figure 3 This is an evaluation schematic diagram provided by an embodiment of this specification. As Figure 3 shown, it includes 5 parts. Figure 3 Part 1 in it shows determining the operating furnace profile level according to the parameter interval. The operating furnace profile level can include level 1, level 2, or level 3. When the interval corresponding to parameter 1 is 1, the interval corresponding to parameter 2 is 1, and the interval corresponding to parameter 3 is 1, it is determined that the operating furnace profile level is level 1; when the interval corresponding to parameter 1 is 2, the interval corresponding to parameter 2 is 2, and the interval corresponding to parameter 3 is 2, it is determined that the operating furnace profile level is level 2; when the interval corresponding to parameter 1 is 3, the interval corresponding to parameter 2 is 3, and the interval corresponding to parameter 3 is 3, it is determined that the operating furnace profile level is level 3. Figure 3 Part 2 in it shows dividing the blast furnace into 3 sections, and each section is further divided into 4 directions. The historical slag skin thickness data at different heights in each direction is collected to obtain the mean value of the historical slag skin thickness data.
[0090] As Figure 3 shown in Part 2 in it, 9 preset height slag skin mean values at different heights are obtained. For example, the first preset height slag skin mean value from top to bottom is obtained by performing a mean value operation on the historical slag skin height data at the same height of the furnace stack.
[0091] Step 1005: The computing device generates historical slag skin thickness profile reference data based on the preset average slag skin value at a preset height.
[0092] In some embodiments, the slag skin thickness profile of the blast furnace is represented by the preset average slag skin values at different heights, and the historical slag skin thickness profile reference data includes multiple preset average slag skin values.
[0093] As Figure 3 shown in Part 3 of , the slag skin thickness profiles of three blast furnace sections are respectively shown. Taking the furnace body as an example, the furnace body corresponds to three preset average slag skin values. Assuming that the first slag skin thickness profile from left to right is the slag skin thickness profile corresponding to the furnace body, the slag skin thickness profile of the furnace body is represented by the three preset average slag skin values corresponding to the furnace body, and the furnace type grade is matched with the slag skin thickness profile to obtain the furnace type grade - slag skin thickness profile reference pattern.
[0094] Step 1006: The computing device determines the corresponding relationship between the historical slag skin thickness profile reference data and the furnace type grade based on the historical slag skin thickness profile reference data and the furnace type grade.
[0095] In some embodiments, the computing device determines the furnace type grade through Steps 1001 - 1003, then determines the historical slag skin thickness profile reference data through Steps 1004 - 1005, and directly corresponds the historical slag skin thickness profile reference data with the furnace type grade.
[0096] For example, as Figure 3 shown, assuming that the operating furnace type grade is determined to be Grade 3 in Part 1, then the furnace type grade corresponding to the historical slag skin thickness profile reference data obtained in Part 3 is Grade 3.
[0097] In addition, Steps 1004 to 1005 can be executed before Step 1001, or can be executed before Step 101. Steps 1001 to 1003 can be executed before Step 1004, or can be executed before Step 103. Alternatively, Steps 1004 to 1005 are executed before Step 101, and Steps 004 to 1005 are executed before Step 103. The execution order of the steps is not limited in this specification.
[0098] In a possible implementation manner, Step 101 may specifically include:
[0099] Step 1011: The computing device performs similarity matching on the blast furnace section angular slag skin value and the historical slag skin thickness profile reference data through a regularization mapping technique to generate a reference mapping degree value corresponding to the historical slag skin thickness profile reference data.
[0100] In some embodiments, the computing device performs a similarity match between the current blast furnace section angle slag skin value and the previously generated historical slag skin thickness profile reference data, determines the similarity between the blast furnace section angle slag skin value and at least one historical slag skin thickness profile reference data, and uses the similarity between the blast furnace section angle slag skin value and the historical slag skin thickness profile reference data as the reference mapping degree value corresponding to the historical slag skin thickness profile reference data. The larger the reference mapping degree value, the higher the similarity between the blast furnace section angle slag skin value and the historical slag skin thickness profile reference data.
[0101] As Figure 3 shown in part 4 of [], the blast furnace is divided into three sections: the furnace shaft, the furnace waist, and the furnace belly. Each section is further divided into four angles. The blast furnace section angle slag skin value refers to the slag skin values at different heights corresponding to a certain angle in the blast furnace section, thereby obtaining the current slag skin thickness profile for each angle in the blast furnace section. The current slag skin thickness profile is represented by the blast furnace section angle slag skin value. The computing device performs a similarity match between the current slag skin thickness profile and multiple different historical slag skin thickness profile reference data to obtain the reference mapping degree values corresponding to the multiple historical slag skin thickness profile reference data.
[0102] Step 1012: The computing device determines the maximum reference mapping degree value based on the reference mapping degree values corresponding to the historical slag skin thickness profile reference data, and uses the maximum value as the target reference mapping degree value.
[0103] In some embodiments, the computing device compares the reference mapping degree values corresponding to the multiple historical slag skin thickness profile reference data to determine the maximum reference mapping degree value. Alternatively, when the number of reference mapping degree values is 1, the computing device uses the reference mapping degree value as the maximum reference mapping degree value.
[0104] Step 1013: The computing device determines the target historical slag skin thickness profile reference data based on the historical slag skin thickness profile reference data corresponding to the target reference mapping degree value.
[0105] In some embodiments, the computing device uses the historical slag skin thickness profile reference data corresponding to the target reference mapping degree value as the target historical slag skin thickness profile reference data.
[0106] The computing device executes steps 1011 - 1013 to generate the target historical slag skin thickness profile reference data and the target reference mapping degree value corresponding to a single angle in the blast furnace section. When the blast furnace is divided into multiple blast furnace sections and / or multiple angles are divided, the computing device repeatedly executes steps 1011 - 1013 until the target historical slag skin thickness profile reference data and the target reference mapping degree value corresponding to each angle in the blast furnace section are calculated.
[0107] In a possible implementation, step 102 may specifically include: when the number of target reference mapping degree values is multiple, it indicates that the blast furnace is divided into multiple blast furnace segments, and / or multiple angles are divided. The calculation device performs a mean operation on the multiple target reference mapping degree values to generate a reference mapping degree mean. Or, when the number of target reference mapping degree values is 1, the calculation device uses the target reference mapping degree value as the reference mapping degree mean.
[0108] In a possible implementation, step 103 may specifically include: when the reference mapping degree mean is within the mapping standard threshold range, the calculation device uses the furnace type grade corresponding to the target historical slag skin thickness profile reference data as the blast furnace segment angle furnace type grade corresponding to the blast furnace segment angle slag skin value.
[0109] In some embodiments, as Figure 3 shown in part 4 of
[0110] In a possible implementation, step 104 may specifically include:
[0111] Step 1041: The calculation device generates a single-angle operating furnace type status value based on the blast furnace segment angle furnace type grade.
[0112] In some embodiments, the calculation device determines the grade scores corresponding to multiple blast furnace segment angle furnace type grades; performs a weighted sum operation on the grade scores and the blast furnace segment weight factor corresponding to the blast furnace segment to generate a single-angle operating furnace type status value.
[0113] When the scores corresponding to the three levels of the furnace belly position operation furnace type, namely level 1, level 2, and level 3, are D11, D12, and D13 respectively, the scores corresponding to the three levels of the furnace waist position operation furnace type, namely level 1, level 2, and level 3, are D21, D22, and D23 respectively, and the scores corresponding to the three levels of the furnace body position operation furnace type, namely level 1, level 2, and level 3, are D31, D32, and D33 respectively, and when the weight factors corresponding to the furnace belly, furnace waist, and furnace body are set as Q1, Q2, and Q3 respectively by applying the spatial weight dynamic function, assuming that the scores corresponding to the operation furnace type levels at the first angle of the furnace belly, the first angle of the furnace waist, and the first angle of the furnace body are D11, D22, and D33 respectively, based on the weighted summation operation, calculate the first product of the furnace belly weight factor Q1 and the score D11 corresponding to the first angle of the furnace belly, the second product of the furnace waist weight factor Q2 and the score D22 corresponding to the first angle of the furnace waist, and the third product of the furnace body weight factor Q3 and the score D33 corresponding to the first angle of the furnace body; add the first product, the second product, and the third product to obtain the single - angle operation furnace type state value. The calculation formula for the single - angle operation furnace type state value corresponding to the first angle can be expressed as A1 = Q1 * D11+Q2 * D22+Q3 * D33, where A1 represents the single - angle operation furnace type state value corresponding to the first angle.
[0114] As Figure 3 shown in part 4, four angles are divided for the blast furnace, and the single - angle operation furnace type state value corresponding to each angle is calculated, obtaining the single - angle operation furnace type state values A1, A2, A3, and A4 corresponding to the first angle , the second angle , the third angle and the fourth angle respectively.
[0115] Step 1042: The calculation device generates the full - angle operation furnace type activity index based on the single - angle operation furnace type state value.
[0116] In some embodiments, the calculation device determines the single - angle weight factor corresponding to a single angle; through the weighted summation operation, based on the single - angle weight factor and the single - angle operation furnace type state value, the full - angle operation furnace type activity index is generated.
[0117] For example, as Figure 3 shown in part 5, angle 1 is the first angle , state A1 is the single - angle operation furnace type state value corresponding to the first angle , and weight J1 is the first angle The corresponding single - angle weight factor is J1; similarly, the single - angle operating furnace type state values corresponding to 4 angles respectively and the corresponding single - angle weight factors are known. The formula for the full - angle operating furnace type activity index can be expressed as G = A1*J1 + A2*J2 + A3*J3 + A4*J4, where G represents the full - angle operating furnace type activity index, thus obtaining the activity index of the three - dimensional full - angle of the blast furnace.
[0118] In a possible implementation manner, step 105 may specifically include:
[0119] Step 1051, the computing device determines the target state interval corresponding to the full - angle operating furnace type activity index.
[0120] In some embodiments, multiple state intervals are preset, and the state intervals correspond to the furnace type states. The state interval where the full - angle operating furnace type activity index is located is used as the target state interval.
[0121] Step 1052, the computing device determines the target furnace type state corresponding to the full - angle operating furnace type activity index based on the correspondence between the target state interval and the furnace type state, and uses the target furnace type state as the full - angle furnace type state.
[0122] In some embodiments, for example, 3 state intervals are preset, namely state interval 1, state interval 2, and state interval 3. The furnace type states include excellent state, general state, and poor state; among them, state interval 1 corresponds to the excellent state, state interval 2 corresponds to the general state, and state interval 3 corresponds to the poor state. When the current state interval is state interval 1, the full - angle furnace type state is determined to be the excellent state.
[0123] As Figure 3 shown in part 5 of , the full - angle state is obtained based on the full - angle score.
[0124] In a possible implementation manner, the evaluation result of the operating furnace type state includes the furnace type correction state. Step 106 may specifically include: the computing device corrects the full - angle furnace type state through the blast furnace section angle furnace type grade to generate the furnace type correction state.
[0125] In some embodiments, when the blast furnace section angle furnace type grade is too low or too high, the full - angle furnace type state can be appropriately corrected to make the full - angle furnace type state downshift or upshift appropriately.
[0126] The computing device displays the evaluation result of the operating furnace type state, enabling relevant personnel to know the furnace type state in real - time and more directly.
[0127] In a possible implementation manner, after step 102, it further includes: step 107, the computing device updates the mapping standard threshold range based on the fact that the mean value of the reference mapping degree is outside the mapping standard threshold range, and executes step 101.
[0128] In some embodiments, the mapping standard threshold range is a range greater than or equal to the mapping threshold. The computing device updates the mapping standard threshold range based on the mean of the reference mapping degree being less than the mapping threshold. In addition, at least one of the corresponding relationship between the historical slag skin thickness profile reference data and the furnace type grade, the state interval, the blast furnace section weight factor, the single angle weight factor, and the grade score can be updated.
[0129] Figure 4 The following is a flowchart of an online evaluation provided by an embodiment of this specification. As Figure 4 shown, the computing device collects historical data on the blast furnace slag skin thickness and smelting data to obtain key parameters of the furnace type state; obtains the key parameters of the grid-shaped furnace type state through blast furnace experience; establishes a general rule for the blast furnace operating furnace type grade through fuzzy matching to correspond the key parameters of the grid-shaped furnace type state with the furnace type grade; applies statistics and spatial segmentation to establish a blast furnace operating furnace type grade - slag skin thickness profile reference model; uses a spatial weight dynamic function to assign a weight factor to the blast furnace section, and through regular mapping, generates a blast furnace single angle three-stage operating furnace type grade evaluation and mapping degree; obtains the mean value of the mapping degree based on the mapping degree; when the mean value of the mapping degree is greater than or equal to the mapping threshold, generates a blast furnace three-dimensional full-angle operating furnace type state evaluation through angle activity; the real-time evaluation result of the blast furnace three-dimensional operating furnace type includes the blast furnace three-dimensional full-angle operating furnace type state evaluation. When the mean value of the mapping degree is less than the mapping threshold, an adaptive update mechanism is started to re-collect the historical data on the blast furnace slag skin thickness and smelting data.
[0130] An embodiment of this specification provides a method for evaluating the furnace type state. Based on the historical slag skin thickness profile reference data, according to the slag skin value at the blast furnace section angle, the target historical slag skin thickness profile reference data and the target reference mapping degree value corresponding to the slag skin value at the blast furnace section angle are determined. The slag skin value at the blast furnace section angle is the slag skin value at a preset angle of the blast furnace section. A reference mapping degree average value is generated based on the target reference mapping degree value. Based on the fact that the reference mapping degree average value is within the mapping standard threshold range, according to the corresponding relationship between the target historical slag skin thickness profile reference data and the furnace type grade, the blast furnace section angle furnace type grade corresponding to the slag skin value at the blast furnace section angle is determined. Based on the blast furnace section angle furnace type grade, a full-angle operation furnace type activity index is generated. Based on the full-angle operation furnace type activity index, a full-angle furnace type state is generated. Based on the full-angle furnace type state and the blast furnace section angle furnace type grade, an operation furnace type state evaluation result is generated. Thus, based on the actual blast furnace data, without the need to add auxiliary equipment and without other cost burdens, according to the slag skin value at the blast furnace section angle collected in real time, by making a similarity match with the historical slag skin thickness profile reference data, the reference mapping degree average value is obtained. When the reference mapping degree average value is within the mapping standard threshold range, the target reference mapping degree value of the slag skin value at the blast furnace section angle and the historical slag skin thickness profile reference data is relatively high. Then, the blast furnace section angle furnace type grade is determined, and then the full-angle furnace type state is obtained. The full-angle furnace type state is further corrected according to the blast furnace section angle furnace type grade to obtain the final operation furnace type state evaluation result. And in practical applications, usually, multiple blast furnace sections and multiple angles are analyzed. The evaluation mechanism deeply integrates intelligent technology and on-site experience. The evaluation process comprehensively considers and analyzes from a three-dimensional space. The evaluation result is accurate, conforms to the actual situation, has strong adaptability and interpretability, can effectively assist operators in controlling the operation furnace type state of the blast furnace, can evaluate the operation furnace type state dynamically and accurately for a long time, is convenient for relevant personnel to know and adjust the furnace type state, is convenient for furnace condition management, and improves the stable and smooth operation level of the blast furnace.
