Description

Technical Field

[0001] The present application relates to the technical field of blast furnace ironmaking, and more specifically, to a method for determining a dead material column corner angle and related equipment. Background Art

[0002] In the blast furnace smelting process, the dead material column is a key component in the furnace, and its stability and shape have a vital impact on the overall operating efficiency and life of the blast furnace. The dead material column is composed of a relatively stable coke layer below the tuyere whirlpool zone, which is immersed in slag and iron liquid for a long time. Its air permeability and liquid permeability are directly related to the smooth operation and furnace stability of the blast furnace; once these properties of the dead material column deteriorate, such as poor air permeability and liquid permeability, it is very easy to cause abnormal furnace conditions such as suspended materials and poor slag discharge, which seriously affects the production efficiency and safety of the blast furnace.

[0003] However, the accurate determination of the dead material column corner angle, as an important indicator for evaluating its shape and position, has always been a major problem in blast furnace management and maintenance. Traditional methods often rely on empirical judgment and indirect measurement, and it is difficult to directly obtain accurate angle information without stopping the furnace or during overhaul. This not only increases the difficulty and cost of blast furnace overhaul, but may also lead to incomplete cleaning of residual iron in the furnace during the overhaul process, further aggravating the damage of the carbon bricks at the bottom of the furnace and shortening the overall service life of the blast furnace.

[0004] With the continuous development of blast furnace smelting technology and the increasing requirements for blast furnace maintenance accuracy, the accurate determination of the dead material column corner angle is particularly important; it can not only guide the precise positioning and cleaning during the blast furnace overhaul process, but also estimate the furnace bottom erosion through regular measurement when no overhaul is required, providing a scientific basis for the daily maintenance of the blast furnace, thereby effectively extending the service life of the blast furnace, improving work quality and reducing maintenance costs.

[0005] At present, although some technical means have been tried to measure the dead material column corner angle, most of these methods have problems such as insufficient accuracy, complex operation or high cost, and it is difficult to meet the increasingly refined needs of blast furnace management. That is, the existing technology has a technical problem of low accuracy in determining the dead material column corner angle. Summary of the invention

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. In the following description, it is related to "some embodiments", which describes a subset of all possible embodiments, but it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0029] See also Figure 1 , Figure 1 1 is a flow chart of a method for determining a dead material column corner angle provided in an embodiment of the present application. The method may specifically include the following steps 101 to 103:

[0030] Step 101, traverse and obtain temperature data of thermocouples;

[0031] Specifically, a thermocouple is a temperature sensor that measures temperature by using the principle that when two different metals or semiconductor materials are connected together, an electromotive force (voltage) is generated at the two junctions due to the thermoelectric effect (Seebeck effect), and that the electromotive force has a certain functional relationship with the temperature.

[0032] Exemplarily, the temperature value currently recorded by each thermocouple may be read one by one in a preset order to ensure that the temperature data of the thermocouples are collected without omission for subsequent analysis.

[0033] By implementing step 101, the temperature distribution of each area in the furnace can be fully understood, providing detailed data support for subsequent analysis.

[0034] Step 102, when the acquired temperature data is greater than or equal to the preset temperature, the currently traversed thermocouple is determined as the target thermocouple and the traversal is stopped;

[0035] Specifically, the preset temperature is a pre-set temperature threshold used as a judgment standard in the temperature monitoring process. It is used to determine when to mark a thermocouple as a "target thermocouple"; when the temperature measured by the thermocouple reaches or exceeds this preset value, it indicates that the temperature of the area has reached or exceeded a certain level of concern. The target thermocouple refers to a thermocouple whose measured temperature data reaches or exceeds the preset temperature; in a series of thermocouples, the target thermocouple represents the area with the highest temperature or the area that has reached a certain process condition.

[0036] For example, during the traversal process, for each thermocouple, its current temperature data will be compared with a preset temperature threshold. If the temperature data of a thermocouple is greater than or equal to the threshold, the thermocouple will be regarded as a target thermocouple and its relevant information (such as position, temperature value, etc.) will be recorded for subsequent analysis.

[0037] By implementing step 102 and setting a preset temperature threshold, the target thermocouple associated with the corner position of the dead material column can be accurately located.

[0038] Step 103, determining the angle of the dead material column corner according to the traversal sequence number of the target thermocouple;

[0039] Specifically, the traversal sequence number refers to the order in which each thermocouple is accessed when traversing a series of thermocouples; during the traversal process, each thermocouple will be assigned a unique sequence number, usually starting from 1 and increasing in sequence. Dead material column refers to a solid material block area that is difficult to flow formed at the bottom of a smelting furnace (such as a blast furnace) due to the accumulation of material layers and the flow of molten metal; the dead material column has an important influence on the flow of molten metal in the furnace and the stability of the furnace condition. Its shape, size and position will affect the smelting efficiency and the service life of the furnace. The corner of the dead material column refers to the corner area formed by the contact between the dead material column and the bottom of the furnace.

[0040] Exemplarily, first, the serial number of the target thermocouple during the traversal process can be recorded, and this serial number reflects the position of the target thermocouple relative to other thermocouples; then, the serial number of the target thermocouple is combined with the geometric parameters of the furnace (such as radius, total number of thermocouples, etc.) using a preset algorithm or formula to calculate the position of the target thermocouple relative to the center of the furnace or a reference point; finally, based on this position information and the preset relationship or model between the dead material column corner and the thermocouple position, the angle of the dead material column corner is inferred.

[0041] By implementing step 103, a mathematical relationship is established between the traversal sequence number of the target thermocouple and the corner angle of the dead material column, thereby achieving quantitative analysis of the corner angle, avoiding the subjectivity and ambiguity in the traditional method, and improving the accuracy of angle determination.

[0042] In summary, the embodiments of the present application can obtain the detailed temperature distribution of each area in the furnace by traversing all thermocouples, which provides a solid foundation for subsequent analysis; by presetting the temperature threshold, the target thermocouple can be quickly and accurately positioned; and then a clear mathematical relationship is established between the traversal sequence number of the target thermocouple and the corner angle of the dead material column, thereby realizing the quantitative analysis of the corner angle. This quantitative analysis method avoids the subjectivity and ambiguity in the traditional method, making the angle determination more objective and accurate. In summary, the vehicle safety driving warning method provided in the embodiments of the present application realizes the efficient and accurate determination of the corner angle of the dead material column through the steps of comprehensive data collection, precise target positioning, and quantitative analysis of angles.

[0043] In some embodiments, the aforementioned step 101 may include: starting from one end of the furnace diameter line segment, traversing and acquiring temperature data of thermocouples, wherein the thermocouples are arranged in the upper surface area of ​​the furnace bottom and are evenly arranged along the furnace diameter line segment.

[0044] Specifically, the furnace diameter line segment refers to a straight line segment from one edge of the furnace to the other edge of the furnace. This line segment passes through the diameter of the furnace. The furnace diameter line segment provides a reference frame. The thermocouples arranged along this line segment can evenly cover the upper surface area of ​​the furnace bottom, thereby ensuring that the temperature of the entire area can be effectively monitored.

[0045] For example, one end of the furnace cylinder diameter segment can be first determined as the starting point of the traversal, and then according to a predetermined traversal direction (such as the direction toward the other end of the diameter segment) and step length (in this example, since the thermocouples are evenly arranged, the step length can be regarded as the distance or serial number difference between adjacent thermocouples), the temperature data of the thermocouples arranged in the upper surface area of ​​the furnace bottom and evenly arranged along the furnace cylinder diameter segment are accessed and read one by one.

[0046] Through the implementation of the above embodiments, the arrangement and traversal order of the thermocouples are clarified, that is, the traversal starts from one end of the furnace diameter segment. This arrangement ensures that the thermocouples can evenly cover the upper surface area of ​​the furnace bottom, thereby improving the accuracy and representativeness of temperature data collection; at the same time, the method of traversing from one end simplifies the data processing process, improves the execution efficiency of the method, ensures the orderliness and continuity of data acquisition, and is conducive to improving the accuracy of corner angle determination.

[0047] In some embodiments, the aforementioned step 103 may include: when the traversal number is 1, determining that the corner of the dead material column is 90 degrees; when the traversal number is not 1, determining the first length of the target thermocouple from the furnace wall according to the traversal number, the total number of thermocouples and the radius of the furnace cylinder; determining the angle of the dead material column corner according to the first length, the depth of the dead iron layer and the second length, wherein the second length is the projection length of the iron outlet channel on the furnace bottom.

[0048] Specifically, the furnace wall refers to the inner wall of the blast furnace, which is part of the blast furnace structure and is used to withstand the internal high temperature and chemical reaction environment. The first length refers to the straight-line distance from the target thermocouple position to the furnace wall (one end of the furnace diameter line segment). The second length refers to the projected length of the taphole channel at the bottom of the furnace. This length is another important parameter for calculating the corner angle of the dead material column. It represents the projection of the taphole channel on the horizontal plane. The taphole channel refers to the channel in the blast furnace used to discharge molten metal (usually molten iron).

[0049] Exemplarily, first, the first length of the target thermocouple from the furnace wall can be determined by calculation based on the traversal number, the total number of thermocouples and the radius of the furnace hearth. This usually involves mapping the traversal number to the physical position of the thermocouple, and then performing calculations based on the arrangement of the thermocouples and the geometric dimensions of the furnace hearth; then, the known dead iron layer depth and the second length (i.e., the projected length of the iron outlet channel on the furnace bottom) can be combined with the first length to determine the angle of the dead material column corner through trigonometric calculations or a preset model.

[0050] Through the implementation of the above-mentioned embodiments, parameters such as the traversal number, total number, and furnace radius of the thermocouples are introduced, and a mathematical relationship between the target thermocouple position and the corner angle of the dead material column is established. This quantitative analysis method improves the accuracy of angle determination, provides a more reliable basis for blast furnace operation, and makes the determination of the corner angle more accurate.

[0051] In some embodiments, the method for determining the corner angle of the dead material column may also include: obtaining a third length of the tap hole channel and a target angle between the tap hole channel and the horizontal plane; calculating the product of the third length and the cosine value of the target angle to obtain a second length.

[0052] Exemplarily, first, the third length of the iron outlet channel can be obtained, and the target angle between the iron outlet channel and the horizontal plane can be obtained, which angle describes the inclination of the iron outlet channel relative to the horizontal plane; then, according to the properties of trigonometric functions, the product of the third length and the cosine value of the target angle is calculated, and this product is the projection length of the iron outlet channel on the horizontal plane of the furnace bottom, which is the second length; this step of calculation is based on geometric principles and the application of trigonometric functions, and can accurately reflect the actual influence range of the iron outlet channel on the furnace bottom.

[0053] By implementing the above embodiment, the third length and target angle of the tap hole channel are obtained, and the second length is calculated, which helps to more accurately reflect the actual working conditions and further improve the accuracy of corner angle determination.

[0054] In some embodiments, the above-mentioned determining the first length of the target thermocouple from the furnace wall according to the traversal sequence number, the total number of thermocouples and the furnace radius may include: substituting the traversal sequence number, the total number of thermocouples and the furnace radius into a first length calculation formula to calculate the first length, wherein the first length calculation formula is:

[0055]

[0056] Where L1 is the first length, R is the radius of the furnace, n is the total number of thermocouples, and i is the traversal number.

[0057] For example, formula (1) can be used to calculate the first length of the target thermocouple from the furnace wall; specifically, if the furnace radius R is 5 meters, the total number of thermocouples n is 10, and the currently traversed thermocouple number i is 3, then these values ​​are substituted into formula (1) to obtain the first length L_1 of the thermocouple from the furnace wall as (25 / 10)3=3 meters. This calculation result provides key position information for the subsequent determination of the dead material column corner angle.

[0058] Through the implementation of the above embodiment, the first length is calculated by the formula, which simplifies the calculation process and improves the calculation efficiency.

[0059] In some embodiments, the above-mentioned determining the angle of the dead material column corner according to the first length, the dead iron layer depth and the second length may include: substituting the first length, the dead iron layer depth and the second length into the corner angle calculation formula to calculate the angle of the dead material column corner, wherein the corner angle calculation formula is:

[0060]

[0061] Wherein, α is the angle of the dead material column corner, h is the depth of the dead iron layer, L1 is the first length, and L2 is the second length.

[0062] For example, assuming that in a certain blast furnace, the measured first length is 3 meters, the dead iron layer depth is 2 meters, and the second length is 1 meter; substituting these values ​​into formula (2), that is, α=arctan(2 / (3-1))=arctan(1)=45°, the angle of the dead material column corner is calculated to be 45°.

[0063] Through the implementation of the above embodiment, based on the principles of geometry and trigonometric functions, the angle of the dead material column corner can be accurately calculated, thereby achieving precise calculation of the corner angle.

[0064] In some embodiments, the preset temperature is 100 degrees Celsius.

[0065] For example, if the temperature measured by a thermocouple in a certain area of ​​the blast furnace rises rapidly, when the temperature exceeds a preset 100 degrees Celsius, the thermocouple is immediately identified as a target thermocouple and the traversal process is stopped.

[0066] Through the implementation of the above embodiment, based on actual blast furnace operation experience and technical requirements, it can be ensured that the thermocouples related to the corner position of the dead material column can be identified within a reasonable range, thereby improving the practicality and operability of the method.

[0067] Below, taking the preset temperature of 100 degrees Celsius as an example, three embodiments in specific implementation scenarios are listed.

[0068] First embodiment:

[0069] The temperature measurement data of the thermocouple at the bottom of the blast furnace are as follows:

[0070] Traversal sequence number 1 2 3 4 5 6 7 8 9 Temperature(℃) 122 117 124 135 126 118 117 124 120

[0071] If the temperature of the first thermocouple (traversal number is 1) is > 100°C, the corner angle of the dead material column at the bottom of the furnace is 90°.

[0072] Second embodiment:

[0073] The temperature measurement data of the thermocouple at the bottom of the blast furnace are as follows:

[0074]

[0075] There are 9 temperature measuring points (thermocouples) in total. If the temperature of the first thermocouple is <100°C, then continue to traverse the temperature of the second thermocouple <100°C, then continue to traverse the temperature of the third thermocouple >100°C. It is clear that the first length of the temperature measuring point from the furnace wall is (2*6.8 / 9)*3=4.53m.

[0076] The length of the taphole before the blast furnace is shut down is 3.5m, and the target angle of the taphole is 9°. The projection length of the taphole channel on the furnace bottom can be calculated as taphole length * cosine value of target angle = 3.5 * COS9° = 3.46m.

[0077] It is clear that the radius of the blast furnace hearth is 6.8m, and the designed dead iron layer depth of the blast furnace is 2.6m. Then the corner angle of the dead material column at the bottom of the furnace is arctan(2.43)=67.6°.

[0078] Third embodiment:

[0079] The temperature measurement data of the thermocouple at the bottom of the blast furnace are as follows:

[0080]

[0081] There are 9 temperature measuring points in total. If the temperature of the first thermocouple is <100℃, then continue to traverse the second thermocouple temperature <100℃, then continue to traverse the third thermocouple temperature <100℃, then continue to traverse the fourth thermocouple temperature >100℃. It is clear that the distance between this temperature measuring point and the furnace wall is (2*6.3 / 9)*4=5.6m.

[0082] The length of the taphole before the blast furnace is shut down is 3.5m, and the target angle of the taphole is 9°. The projected length of the taphole channel at the bottom of the furnace can be calculated as 3.5*COS9°=3.46m.

[0083] It is clear that the radius of the blast furnace hearth is 6.3m, and the designed dead iron layer depth of the blast furnace is 2.8m. Then the corner angle of the dead material column at the bottom of the furnace is arctan(1.31)=52°.

[0084] The method for determining the dead material column corner angle provided in the embodiment of the present application can be applied to the following examples: Figure 2 The blast furnace hearth shown.

[0089] In some embodiments, the angle determination unit 203 is further used to substitute the traversal sequence number, the total number of thermocouples and the furnace radius into the first length calculation formula to calculate the first length, wherein the first length calculation formula is: Where L1 is the first length, R is the radius of the furnace, n is the total number of thermocouples, and i is the traversal number.
