[0002] Blast furnace charge distribution refers to the distribution of charge (mainly coke and ore) in the blast furnace throat during the blast furnace ironmaking process. Blast furnace charge passes through the charge tank, the center throat pipe, the chute and the blast furnace top in sequence, and finally enters the blast furnace. Among them, the throttle valve opening of the center throat pipe determines the size of the charge flow (the charge flow refers to the ratio between the charge weight and the charge distribution time). There is a positive correlation between the charge flow and the throttle valve opening. The larger the throttle valve opening, the larger the charge flow, and the smaller the throttle valve opening, the smaller the charge flow, but the charge flow and the throttle valve opening are not a simple linear relationship.

[0003] For blast furnaces that have been overhauled or newly built, the relationship between the material flow and the throttle valve opening needs to be measured. In the related art, the relationship between the material flow and the throttle valve opening corresponding to the ore distribution is measured mainly by manually setting the throttle valve opening after the furnace is opened to adjust and record the material flow, and finally the relationship between the throttle valve opening and the material flow is obtained by summarizing. However, this method has a long measurement cycle and low efficiency. Summary of the invention

[0044] The embodiment of the present application solves the technical problems of long cycle and low efficiency in determining the relationship between the material flow and the throttle valve opening of the charge distribution in the prior art by providing a blast furnace charge distribution method.

[0045] The technical solution of the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0046] A method for distributing charge to a blast furnace, the method comprising: obtaining a reference correlation relationship between a material flow corresponding to a first charge distributed in a target blast furnace and a throttle valve opening; adjusting the reference correlation relationship according to the correlation between the first charge and the second charge, and obtaining a simulated correlation relationship between a material flow corresponding to a second charge distributed in the target blast furnace and a throttle valve opening; wherein the distribution frequency of the first charge is higher than the distribution frequency of the second charge; distributing the second charge in the target blast furnace according to the simulated correlation relationship, and obtaining an actual correlation relationship between a material flow and a throttle valve opening when distributing the second charge in the target blast furnace; updating the simulated correlation relationship according to the actual correlation relationship, and using the updated simulated correlation relationship as a target correlation relationship between a material flow corresponding to the second charge distributed in the target blast furnace and a throttle valve opening, so that the target blast furnace distributes the second charge according to the target correlation relationship.

[0047] This embodiment relies on the reference association relationship of the first charge with a higher frequency of distribution, and the correlation between the first charge and the second charge, and adjusts the reference association relationship to quickly obtain the simulated association relationship of the second charge. The simulated association relationship can be used to realize automatic distribution of the second charge, thereby improving the distribution efficiency and accuracy of the second charge. The simulated association relationship is then fine-tuned according to the actual association relationship in the actual distribution process of the second charge to obtain a more accurate target association relationship. The second charge is automatically distributed according to the target association relationship, which can not only continuously improve the distribution efficiency of the second charge, but also continuously improve the distribution accuracy of the second charge, thereby ensuring the stability of the blast furnace during operation.

[0048] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0049] First of all, the term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0050] The process of blast furnace charging is as follows: the charge in the charging tank passes through the central throat of the charging pipe to the chute, and then enters the top of the blast furnace through the chute. The chute of blast furnace charging is the key equipment of blast furnace charging. The blast furnace can make the charge fall to the specified circumferential position by adjusting the different rotation angles of the chute, and can make the charge fall to the specified radial position by adjusting the tilting angle of the chute.

[0051] The charge of the chute comes from the center throat of the material discharge. The throttle valve opening of the center throat determines the size of the material flow (or material flow). Among them, the material flow is the ratio between the weight of the charge and the distribution time. There is a positive correlation between the material flow and the throttle valve opening. The larger the throttle valve opening, the larger the material flow, and the smaller the throttle valve opening, the smaller the material flow. However, the material flow and the throttle valve opening are not a simple linear relationship. In the process of blast furnace distribution, it is required to adjust the throttle valve opening to load the charge in the material tank into the specified distribution position within the specified time, so it is necessary to set an accurate throttle valve opening.

[0052] For a blast furnace that has undergone an overhaul or a newly built blast furnace, the relationship between the charge flow and the throttle valve opening needs to be measured, and the measurement method provided in the relevant technology needs to be carried out throughout the entire charging process. Before the final relationship between the charge flow and the throttle valve opening is determined, manual charging is achieved by manually setting the throttle valve opening, resulting in low charging accuracy and large errors, which reduces the operating efficiency of the blast furnace.

[0053] In order to solve the above problems, the present application provides Figure 1 A blast furnace charge distribution method is shown, and the method includes steps S11 to S14.

[0054] Step S11, obtaining a reference correlation relationship between the material flow corresponding to the first charge distribution in the target blast furnace and the throttle valve opening;

[0055] Step S12, adjusting the reference correlation relationship according to the correlation between the first charge and the second charge, and obtaining a simulated correlation relationship between the material flow corresponding to the second charge distribution in the target blast furnace and the throttle valve opening;

[0056] Step S13, performing second charge distribution in the target blast furnace according to the simulated correlation relationship, and obtaining an actual correlation relationship between the material flow and the throttle valve opening when the target blast furnace performs the second charge distribution;

[0057] Step S14, updating the simulated association relationship according to the actual association relationship, and using the updated simulated association relationship as the target association relationship between the material flow corresponding to the second charge distribution in the target blast furnace and the throttle valve opening, so that the target blast furnace distributes the second charge according to the target association relationship.

[0058] Regarding step S11, a reference correlation relationship between the material flow corresponding to the first charge distribution in the target blast furnace and the throttle valve opening is obtained.

[0059] The types of charges involved in blast furnace charging mainly include coke, ore, small-size ore, etc. The types of charges for charging may be different in different blast furnaces, and the charging frequencies of different types of charges in the same blast furnace may also be different. For example, for a certain target blast furnace, the amount of coke used after the furnace is opened is large. There may be 480 batches of coke out of 500 batches of charges, and only 20 batches of ore. This means that for the target blast furnace, the charging frequency of coke is high and the charging frequency of ore is very low, so coke can be used as the first charge of the target blast furnace. In other words, the first charge refers to the charge with a relatively high charging frequency in the target blast furnace.

[0060] For the charge with high frequency of distribution, since the distribution is often continuous batches, the distribution error has little effect on the operation of the blast furnace. Due to its high distribution frequency, the relationship between the charge flow and the throttle valve opening can be obtained based on historical data. For example, the relationship between the charge flow and the throttle valve opening of the same type of coke distribution as the target blast furnace is shown in Table 1. Then the relationship between the charge flow and the throttle valve opening corresponding to the coke distribution of the target blast furnace can be determined based on the data in Table 1. For example, when the throttle valve opening is 26.1°, the coke flow is 177.1Kg / s.

[0061] The planned coke loading in Table 1 can be determined based on the blast furnace capacity, throat diameter, furnace waist diameter and other data. It is generally calculated by filling the throat section with a height of 500±50mm. The actual weighing under the trough is obtained by weighing the under-trough weighing scale, and the weighing of the furnace top tank is obtained by weighing the furnace top material tank process.

[0062] Table 1

[0063]

[0064]

[0065] In addition, the relationship between the material flow and the throttle valve opening can also be determined for the furnace with high material distribution frequency through the material distribution process of the preset batch number after the furnace is opened, which can specifically include steps S111 to S113. Among them, the preset batch number can be set according to the actual production situation, for example, it can be about 30.

[0066] Step S111, according to N different preset throttle valve openings, N first charge distributions are implemented to the target blast furnace, and the N different preset throttle valve openings correspond to the N first charge distributions one by one, wherein N is a positive integer;

[0067] Step S112, determining the actual material flow and the actual throttle valve opening corresponding to each first charge distribution;

[0068] Step S113, determining a reference correlation relationship between the material flow corresponding to the first charge distribution in the target blast furnace and the throttle valve opening according to the actual material flow and the actual throttle valve opening corresponding to the N first charge distributions.

[0069] The N preset throttle valve openings can be set according to the actual applicable opening of the throttle valve. For example, during the throttle valve distribution process, when the opening is less than 15°, the charge cannot pass through the throttle valve, so the lower limit of the N preset throttle valve openings is 15°; if the maximum opening of the throttle valve is 55°, then the upper limit of the N preset throttle valve openings is 55°. Therefore, the N preset throttle valve openings can be set within the range of 15°-55°.

[0070] In addition, the step size of the N different preset throttle valve openings can be set according to the accuracy requirement. When the accuracy requirement is low, the step size can be set larger. When the accuracy requirement is high, the step size can be set smaller. Usually, the step size is 1° or 2°.

[0071] N different preset throttle valve openings are used to distribute the materials respectively, and the actual material flow and the actual throttle valve opening corresponding to each preset throttle valve opening in the N distribution processes are measured. According to the N groups of corresponding actual material flow and actual throttle valve openings, a reference correlation relationship can be determined. The reference correlation relationship can be a data table as shown in Table 2, or a regression curve obtained based on the scattered data in the data table. When Table 2 is a data table obtained after executing steps S111 to S113, a data regression method can be used to obtain the following: Figure 2 The data curve is shown.

[0072] Table 2

[0073]

[0074] It should be noted that although a preset throttle valve opening is set, there may be errors in the actual operation of the throttle valve, so the actual throttle valve opening needs to be measured.

[0075] The actual throttle valve opening may be 27.2°.

[0076] Regarding step S12, according to the correlation between the first charge and the second charge, the reference correlation is adjusted to obtain a simulated correlation between the material flow corresponding to the second charge distribution in the target blast furnace and the throttle valve opening. The distribution frequency of the first charge is higher than the distribution frequency of the second charge.

[0077] According to the description of step S11, the first charge refers to the charge with a relatively high charge frequency in the target blast furnace, and the second charge involved in step S12 corresponds to the first charge, and the second charge refers to the charge with a relatively low charge frequency in the target blast furnace. For example, the charge frequency of coke is high, which is recorded as the first charge, and the charge frequency of ore is very low, which is recorded as the second charge.

[0078] Since the frequency of the second charge is low and the data that can be collected is limited, if the relationship between the material flow and the throttle valve opening when the second charge is laid is determined in a similar manner to the reference association relationship of the first charge, the second charge laying accuracy will be low. In addition, since the number of batches of the second charge laid during the entire furnace opening period is small, the process of "determining the relationship between the material flow and the throttle valve opening when the second charge is laid" will continue throughout the furnace opening period, and only manual laying can be used, resulting in low laying efficiency, low efficiency in determining the relationship between the material flow and the throttle valve opening when the second charge is laid, and low laying accuracy.

[0079] In order to solve this problem, this embodiment determines the relationship between the material flow and the throttle valve opening when the second charge is distributed based on the reference association relationship corresponding to the first charge determined in step S11 and the correlation between the first charge and the second charge in terms of material properties, so as to improve the efficiency of determining the relationship between the material flow and the throttle valve opening when the second charge is distributed, the distribution accuracy and the distribution efficiency, and the specific method is:

[0080] According to the differences in bulk density and flow properties between the first charge and the second charge, the material flow data in the reference association relationship is adjusted, and the reference association relationship after the adjustment of the material flow data is used as the simulated association relationship between the material flow corresponding to the second charge distribution in the target blast furnace and the throttle valve opening.

[0081] Among them, bulk density refers to the weight per unit volume of a pile of normally stacked materials, including the volume of voids between materials, that is, the average density of materials when they are naturally stacked. Flow properties refer to the ability of materials to flow, usually expressed in flow rate.

[0082] For example, when the first charge is coke and the second charge is ore, the coke pile specific gravity is 0.54t / m 3 , ore pile specific gravity 1.75t / m 3 , then the difference in bulk density is 0.54t / m 3 and 1.75t / m 3The difference between the two can be a ratio or other value related to the ratio. Generally, the flow properties of ore are 7%-9% higher than those of coke. Therefore, when the coke flow rate is 200Kg / s, the ore flow rate can be determined to be 200*(1.75 / 0.54)*(1+10%)=713kg / s based on the difference in bulk density and flow properties between the two.

[0083] According to the difference in bulk density and flow property between the first charge and the second charge, the material flow data corresponding to different openings in the reference correlation relationship of the first charge can be adjusted, and then the simulation correlation relationship corresponding to the second charge can be obtained.

[0084] For example, Table 2 is a reference correlation relationship for the first charge, assuming that the ore flowability is 8% higher than the coke flowability, and the coke bulk density is 0.54 t / m 3 , ore pile specific gravity 1.75t / m 3 , then ore flow = coke flow * (1.75 / 0.54) * (1 + 8%), finally, ore flow = 3.5 times coke flow, and then the simulated correlation relationship of the second charge shown in Table 3 can be obtained. The curve regression of the scattered data shown in Table 3 can be obtained as follows Figure 3 It should be noted that the ore flow corresponding to each throttle valve opening in Table 2 can be calculated, or only the ore flow corresponding to multiple throttle valve openings commonly used in ore distribution can be calculated. The specific selection can be made according to actual conditions. Table 3 calculates the ore flow corresponding to all throttle valve openings in Table 2.

[0085] Table 3

[0086] Batch number Coke Flow Throttle valve opening Ore material flow rate (3.5*coke material flow rate) *10kg / s ° *10kg / s 1 17.71 26.1 61.99 2 19.08 27 66.79 3 21.17 28.9 74.10 4 11.79 22 41.26 5 15.75 24.8 55.12 6 15.86 27.9 55.52 7 22.31 29 78.07 8 27.48 32.7 96.17 9 14.16 23.7 49.57 10 10.38 20 36.34 11 18.29 26.8 64.00 12 14.39 23.8 50.37

[0087] This embodiment can determine the relationship between the material flow and the throttle valve opening when the second charge is distributed without actually distributing the second charge, thereby greatly simplifying the complexity of determining the relationship between the material flow and the throttle valve opening when the second charge is distributed, and improving the determination efficiency. Moreover, after determining the simulated correlation relationship, the automatic distribution of the second charge can be realized by relying on the simulated correlation relationship, which improves the distribution accuracy on the one hand and the distribution efficiency on the other.

[0088] Regarding step S13, the second charge distribution is performed in the target blast furnace according to the simulated correlation relationship, and the actual correlation relationship between the material flow and the throttle valve opening when the second charge distribution is performed in the target blast furnace is obtained.

[0089] Since the simulated correlation relationship is obtained based on theory, it may be different from the actual distribution of the second charge. In order to discover and correct this difference, when the second charge is automatically distributed using the simulated correlation relationship, the relationship between the material flow of the second charge and the throttle valve opening during actual distribution can be collected, which can specifically include steps S131-S132.

[0090] Step S131, distributing the second charge in the target blast furnace according to the simulated association relationship, and detecting the actual material flow and the actual throttle valve opening during the second charge distribution process;

[0091] Step S132, determining the actual correlation between the material flow and the throttle valve opening of the target blast furnace during the second charge distribution process according to the actual material flow and the actual throttle valve opening during the second charge distribution process.

[0092] The execution time of step S131 and step S132 can match the actual distribution of the second charge. For example, when the target blast furnace is expected to distribute 500 batches, the 50th batch, the 75th batch, etc. are ore distribution. When the target blast furnace carries out the 50th batch distribution (corresponding to the throttle valve opening of 28°), step S131 and step S132 are executed, and the actual ore flow rate is measured to be 554kg / s; when the target blast furnace carries out the 75th batch distribution (corresponding to the throttle valve opening of 33°), step S131 and step S132 are executed, and the actual ore flow rate is measured to be 950kg / s.

[0093] Regarding step S14, the simulated correlation relationship is updated according to the actual correlation relationship, and the updated simulated correlation relationship is used as the target correlation relationship between the material flow corresponding to the second charge distribution in the target blast furnace and the throttle valve opening, so that the target blast furnace distributes the second charge according to the target correlation relationship.

[0094] When the material flow corresponding to the same throttle valve opening in the actual association relationship and the simulated association relationship is different, the material flow corresponding to the throttle valve opening in the actual association relationship is updated to the simulated association relationship, and the updated simulated association relationship is used as the target association relationship between the material flow corresponding to the second charge distribution in the target blast furnace and the throttle valve opening.

[0095] The same throttle valve opening refers to: if the difference between the two corresponding throttle valve openings in the two relationships is less than or equal to a preset threshold, then the two throttle valve openings can be considered to be the same throttle valve opening. The preset threshold can be set according to actual conditions, such as 0.3°. For example, if the actual association relationship is 27° and the simulated association relationship is 27.3°, then 27° and 27.3° can be considered to be the same throttle valve opening.

[0096] As shown in Table 4, when the throttle valve opening in the actual correlation relationship is 28° (the corresponding throttle valve opening in the simulated correlation relationship is 27.9°), the ore flow rate in the actual correlation relationship is 600kg / s, while the ore flow rate in the simulated correlation relationship is 555.2kg / s. There is a difference between the two, and 600kg / s should be used instead of 555.2kg / s to obtain the updated simulated correlation relationship.

[0097] Table 4

[0098]

[0099] It should be noted that, in actual operation, step S13 and step S14 can be repeatedly executed alternately. For example, after executing step S14, the target association relationship is determined, and step S13 is executed using the target association relationship as a new simulation association relationship, and then step S14 is executed, and the cycle is repeated in sequence. In this way, the relationship between the material flow and the throttle valve opening during the second charge distribution process can be fine-tuned to make the target association relationship more accurate, thereby improving the distribution accuracy and distribution efficiency.

[0100] To summarize, this embodiment relies on the reference association relationship of the first charge with a higher frequency of distribution, and the correlation between the first charge and the second charge, and adjusts the reference association relationship to quickly obtain the simulated association relationship of the second charge. The simulated association relationship can be used to realize automatic distribution of the second charge, thereby improving the distribution efficiency and accuracy of the second charge. The simulated association relationship is then fine-tuned according to the actual association relationship in the actual distribution process of the second charge to obtain a more accurate target association relationship. The second charge is automatically distributed according to the target association relationship, which can not only continuously improve the distribution efficiency of the second charge, but also continuously improve the distribution accuracy of the second charge, thereby ensuring the stability of the blast furnace during operation.

[0101] Based on the same inventive concept, this embodiment provides Figure 4 A blast furnace charge distribution device is shown, the device comprising:

[0102] A reference correlation relationship acquisition module 41 is used to acquire a reference correlation relationship between a material flow corresponding to a first charge distribution in a target blast furnace and a throttle valve opening;

[0103] The simulation correlation determination module 42 is used to adjust the reference correlation according to the correlation between the first charge and the second charge, and obtain the simulation correlation between the material flow corresponding to the second charge distribution in the target blast furnace and the throttle valve opening; wherein the distribution frequency of the first charge is higher than the distribution frequency of the second charge;

[0104] An actual correlation determination module 43 is used to distribute the second charge in the target blast furnace according to the simulated correlation, and obtain the actual correlation between the material flow and the throttle valve opening when the target blast furnace distributes the second charge;
