Depending on the context, the word "if" as used herein may be interpreted as "when" or "while" or "in response to determining".

[0020] In this specification, a method for evaluating the furnace type state is provided. This specification also relates to an apparatus for evaluating 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.

[0021] Figure 1 The flowchart of a method for evaluating the furnace type state provided for one embodiment of this specification is as Figure 1 shown, and the method includes: 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, where the blast furnace section angle slag skin value is the slag skin value of the blast furnace section at a preset angle.

[0022] 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 divided in advance 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.

[0023] For example, Figure 2 The schematic diagram of a blast furnace section provided for one embodiment of this specification is as Figure 2 shown, the blast furnace is divided into 3 sections, which are the furnace shaft , the furnace waist and the furnace belly , each blast furnace section is further divided into 4 angles, which are the first angle from left to right , the second angle , the third angle and the fourth angle . The calculation 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.

[0024] The target historical slag skin thickness profile reference data is the historical slag skin thickness profile reference data with the highest similarity 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, obtain , , …, respectively corresponding target reference mapping degree values.

[0025] Step 102, the calculation device generates a reference mapping degree mean value based on the target reference mapping degree value.

[0026] In some embodiments, as Figure 2 shown, the calculation device will , , …, respectively corresponding target reference mapping degree values perform a mean value operation to obtain the reference mapping degree mean value.

[0027] Alternatively, when the number of target reference mapping degree values is 1, the target reference mapping degree value is used as the reference mapping degree mean value.

[0028] Step 103, the calculation device determines the blast furnace section angle furnace type grade corresponding to the blast furnace section angle slag skin value based on the fact that the reference mapping degree mean value is within the mapping standard threshold range and according to the corresponding relationship between the target historical slag skin thickness profile reference data and the furnace type grade.

[0029] In some embodiments, the mapping standard threshold range is set according to blast furnace experience. For example, the mapping threshold is set according to blast furnace experience, and the range greater than or equal to the mapping threshold is used as the mapping standard threshold range. When the reference mapping degree mean value is greater than or equal to the mapping threshold range, it indicates that the reference mapping degree mean value is within the mapping standard threshold range. At the same time, the reference mapping degree mean 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.

[0030] The computing device determines the blast furnace section angle furnace type level corresponding to the blast furnace section angle slag skin value based on the correspondence between the historical slag skin thickness profile reference data and the furnace type level, as well as the correspondence between the blast furnace section angle slag skin value and the target historical slag skin thickness profile reference data.

[0031] The blast furnace section angle furnace type levels include level 1, level 2, or level 3. The higher the blast furnace section angle furnace type level, the better the furnace type state; alternatively, the blast furnace section angle furnace type levels include excellent level, general level, or poor level. The embodiments of the present invention do not limit the furnace type levels.

[0032] Step 104: The computing device generates a full-angle operation furnace type activity index based on the blast furnace section angle furnace type level.

[0033] In some embodiments, the computing device obtains at least one blast furnace section angle furnace type level 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.

[0034] Step 105: The computing device generates a full-angle furnace type state based on the full-angle operation furnace type activity index.

[0035] 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 states include excellent state, general state, or poor state, etc.

[0036] Step 106: The computing device generates an evaluation result of the operation furnace type state based on the full-angle furnace type state and the blast furnace section angle furnace type level.

[0037] In some embodiments, the computing device modifies the full-angle furnace type state with reference to the blast furnace section angle furnace type level according to blast furnace experience, so that the modified full-angle furnace type state is more in line with the actual state. The evaluation result of the operation furnace type state includes the modified full-angle furnace type state. The evaluation result of the operation furnace type state may also include at least one of the blast furnace section angle furnace type level, the full-angle furnace type state, the full-angle operation furnace type activity index, and the blast furnace section angle slag skin value.

[0038] 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 reference mapping degree average value being 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 operating furnace type activity index is generated; based on the full-angle operating 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 operating 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 slag skin value at the blast furnace section angle and the target reference mapping degree value of the historical slag skin thickness profile reference data are relatively high, and then the blast furnace section angle furnace type grade is determined, and then the full-angle furnace type state is obtained. Based on the blast furnace section angle furnace type grade, the full-angle furnace type state is further corrected to obtain the final operating furnace type 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 type state of the blast furnace and improving the stable and smooth operation level of the blast furnace.

[0039] In this specification, Figure 2 It 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., and 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.

[0040] In a possible implementation manner, before step 103, it further includes: step 1001, the computing device generates key parameters of the furnace type state based on historical slag skin data and smelting data.

[0041] In some embodiments, the slag skin refers to the slag layer attached 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 skin. The computing device collects the historical data of the slag skin thickness at different heights and angles of the blast furnace as the historical slag skin data, and also collects data such as the historical operation data, historical state data, historical economic index data, and slag and iron quality data of the blast furnace as the smelting data.

[0042] The computing device performs data standardization processing on historical slag skin data and smelting data to generate historical slag skin standard data and smelting standard data; based on the historical slag skin standard data and smelting standard data, key parameters of the furnace type state are generated.

[0043] The computing device integrates historical slag skin data and smelting data based on time series. For abnormal phenomena such as inconsistent data frequencies, outliers, and missing values, methods such as blast furnace experience and interpolation are applied for data processing to obtain historical slag skin standard data and smelting standard data.

[0044] The key parameters of the furnace type state include at least one of parameters such as hot metal quality, slag quality, gas utilization rate, fuel ratio, slag skin stability index, and slag skin uniformity index.

[0045] Step 1002: The computing device generates grid interval values of key parameters based on the key parameters of the furnace type state.

[0046] In some embodiments, the computing device determines the grid interval values of the key parameters corresponding to the furnace type state based on the grid interval range corresponding to the key parameters of the furnace type state.

[0047] When the key parameters of the furnace type state include parameters such as hot metal quality, slag quality, gas utilization rate, fuel ratio, slag skin stability index, and slag skin uniformity index, the computing device grids the parameters of hot metal quality, slag quality, gas utilization rate, fuel ratio, slag skin stability index, slag skin uniformity index, etc. 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 skin stability index, grid interval values of slag skin 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.

[0048] Step 1003: The computing device determines the furnace type grade based on the grid interval values of key parameters through blast furnace experience.

[0049] In some embodiments, through blast furnace experience, a general grade rule for the operating furnace type is established, and the computing device determines the furnace type grade corresponding to the grid interval values of key parameters by fuzzy matching according to the general grade rule for the operating furnace type.

[0050] For example, when the hot metal quality is in interval 2, the slag quality is in interval 2, the gas utilization rate is in interval 2, the fuel ratio is in interval 2, the slag skin stability index is in interval 2, and the slag skin uniformity index is in interval 2, the computing device determines that the operating furnace type status level is level 2 based on the general applicability level rule of the operating furnace type through fuzzy matching. When the data is in the hot metal 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 computing device determines that the operating furnace type status level is level 3 based on the general applicability level rule of the operating furnace type through fuzzy matching.

[0051] Step 1004: The computing 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.

[0052] 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, and the mean value operation is performed on the historical slag skin height data of the same height of different angles to obtain the preset height slag skin mean value of different heights.

[0053] 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 shows determining the operating furnace type level according to the parameter interval, and the operating furnace type 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 type 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 type 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 type level is level 3. Figure 3 Part 2 in shows dividing the blast furnace into 3 sections, each section is further divided into 4 directions, collecting the historical slag skin thickness data of different heights in each direction, and obtaining the mean value of the historical slag skin thickness data.

[0054] As Figure 3 shown in Part 2 in , 9 preset height slag skin mean values of 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 of the same height of the furnace stack.

[0055] Step 1005: The computing device generates the historical slag skin thickness profile reference data based on the preset height slag skin mean value.

[0056] In some embodiments, the slag skin thickness profile of the blast furnace is represented by the average slag skin values at preset heights at different heights, and the historical slag skin thickness profile reference data includes multiple average slag skin values at preset heights.

[0057] As Figure 3 shown in part 3, the slag skin thickness profiles of three blast furnace sections are respectively shown. Taking the furnace shaft as an example, the furnace shaft corresponds to three average slag skin values at preset heights. Assuming that the first slag skin thickness profile from left to right is the slag skin thickness profile corresponding to the furnace shaft, the slag skin thickness profile of the furnace shaft is represented by the three average slag skin values at preset heights corresponding to the furnace shaft, 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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. Or, 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.

[0062] In a possible implementation manner, step 101 may specifically include: Step 1011: The computing device performs similarity matching on the blast furnace section angular slag skin values and the historical slag skin thickness profile reference data through the regularization mapping technology to generate a reference mapping degree value corresponding to the historical slag skin thickness profile reference data.

[0063] 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 piece of 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.

[0064] 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, so as to obtain 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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 repeats 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.

[0070] 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.

[0071] 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 furnace type grade of the blast furnace segment corresponding to the blast furnace segment angle slag skin value.

[0072] In some embodiments, as Figure 3 shown in part 4 of

[0073] In a possible implementation, step 104 may specifically include: Step 1041, the calculation device generates a single-angle operating furnace type state value based on the furnace type grade of the blast furnace segment angle.

[0074] In some embodiments, the calculation device determines the grade scores corresponding to multiple furnace type grades of the blast furnace segment angles; performs a weighted sum operation on the grade scores and the blast furnace segment weight factors corresponding to the blast furnace segments to generate a single-angle operating furnace type state value.

[0075] When the scores corresponding to the three levels of the furnace bellows position operation furnace types, 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 types, 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 types, namely level 1, level 2, and level 3, are D31, D32, and D33 respectively, and when the weight factors corresponding to the furnace bellows, furnace waist, and furnace body are set as Q1, Q2, and Q3 respectively by applying the spatial weight dynamic function, assuming that for the first angle of the furnace bellows, the first angle of the furnace waist, and the first angle of the furnace body, the scores corresponding to the operation furnace type levels at the three positions are D11, D22, and D33 respectively, based on the weighted summation operation, calculate the first product of the furnace bellows weight factor Q1 and the score D11 corresponding to the first angle of the furnace bellows, 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.

[0076] As Figure 3 shown in part 4, the blast furnace is divided into 4 angles, and the single-angle operation furnace type state values corresponding to each angle are 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.

[0077] Step 1042: The calculation device generates a full-angle operation furnace type activity index based on the single-angle operation furnace type state value.

[0078] 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, a full-angle operation furnace type activity index is generated.

[0079] 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 operation furnace type state values corresponding to 4 angles respectively and the corresponding single - angle weight factors are known. The formula for the full - angle operation furnace type activity index can be expressed as G = A1*J1 + A2*J2 + A3*J3 + A4*J4, where G represents the full - angle operation furnace type activity index, thus obtaining the activity index of the three - dimensional full - angle of the blast furnace.

[0080] In a possible implementation manner, step 105 may specifically include: Step 1051, the computing device determines the target state interval corresponding to the full - angle operation furnace type activity index.

[0081] 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 operation furnace type activity index is located is used as the target state interval.

[0082] Step 1052, the computing device determines the target furnace type state corresponding to the full - angle operation 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.

[0083] 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.

[0084] As Figure 3 shown in part 5 of , the full - angle state is obtained based on the full - angle score.

[0085] In a possible implementation manner, the operation furnace type state evaluation result 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.

[0086] 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 shift down or up appropriately.

[0087] The computing device displays the operation furnace type state evaluation result, enabling relevant personnel to know the furnace type state in real - time and more directly.

[0088] 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.

[0089] 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 fact that the mean value of the reference mapping degree is less than the mapping threshold. In addition, the correspondence relationship between the historical slag skin thickness profile reference data and the furnace type level, the state interval, the blast furnace section weight factor, the single angle weight factor, and the grade score can be updated at least one of them.

[0090] 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 of 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 furnace type level rule for blast furnace operation through fuzzy matching to make the key parameters of the grid-shaped furnace type state correspond to the furnace type level; applies statistics and spatial segmentation to establish a blast furnace operation furnace type level - slag skin thickness profile reference model; uses the spatial weight dynamic function to assign weight factors to the blast furnace sections, and through regular mapping, generates a three-segment operation furnace type level evaluation and mapping degree for a single angle of the blast furnace; 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 three-dimensional full-angle operation furnace type state evaluation for the blast furnace through angle activity; the real-time evaluation result of the blast furnace three-dimensional operation furnace type includes the three-dimensional full-angle operation furnace type state evaluation for the blast furnace. 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 of the blast furnace slag skin thickness and smelting data.

[0091] 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; the average value of the reference mapping degree is generated based on the target reference mapping degree value; based on the average value of the reference mapping degree being 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, the full-angle operating furnace type activity index is generated; based on the full-angle operating furnace type activity index, the full-angle furnace type state is generated; based on the full-angle furnace type state and the blast furnace section angle furnace type grade, the evaluation result of the operating furnace type state 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 average value of the reference mapping degree is obtained; when the average value of the reference mapping degree is within the mapping standard threshold range, the slag skin value at the blast furnace section angle and the target reference mapping degree value of the historical slag skin thickness profile reference data are relatively high, and 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 evaluation result of the operating furnace type state. 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 the operator in controlling the operating furnace type state of the blast furnace, can evaluate the operating 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.
