Description

Technical Field

[0001] This invention relates to the field of ladle scheduling, and more specifically, to a ladle scheduling method based on molten iron composition. Background Technology

[0002] As competition in the steel industry intensifies, companies are paying more and more attention to the automation of steelmaking production and the optimization of converter steelmaking processes. There are many factors that affect steelmaking during the steel production process, such as the ratio of raw materials, the quality of molten iron, the quality of scrap steel, and the operation of oxygen lances. Among these, the quality of molten iron, i.e. the composition of molten iron, has the greatest impact on converter steelmaking.

If a ladle is substandard, it is usually processed to meet the standards before proceeding to the next step. Alternatively, substandard ladles are fused together based on the experience of the workers to obtain a usable ladle. However, this method of fusion based on human experience needs to be more accurate. Summary of the Invention

[0064] Extensive research by the inventors revealed that currently, molten iron ladles are only transferred to the foundry if they meet quality standards. If a ladle is substandard, it is typically processed to meet quality standards before proceeding to the next step. Alternatively, substandard ladles are fused together based on the experience of the workers to obtain a usable ladle. However, this method of fusion based on human experience lacks precision and requires improvement.

[0065] In view of the above-mentioned problems, this embodiment provides a ladle scheduling method based on molten iron composition, which can calculate and finally obtain a first target combination from unqualified ladles. Thus, qualified ladles can be obtained from unqualified ladles without having to transform unqualified ladles into qualified ladles through other processes, reducing the number of processes.

[0068] The electronic device 100 includes a ladle scheduling device 110 based on molten iron composition, a memory 120, and a processor 130.

[0069] The components of the memory 120 and processor 130 are electrically connected directly or indirectly to achieve data transmission or interaction.

[0071] Please refer to Figure 2 , Figure 2 For application Figure 1 The flowchart of an electronic device 100 based on the composition of molten iron for ladle scheduling is shown below. The method includes each step in detail.

[0072] Step 201: Obtain N defective iron bags.

[0073] Among them, N unqualified iron bags are determined to be unqualified if at least one of the following three information is unqualified: weight information, temperature information, and concentration information.

[0074] Step 202: Determine the first parameter information for each defective iron bag.

[0075] The first parameter information includes first weight information, first concentration information, and first temperature information.

[0076] It should be noted that the first concentration information can be expressed as the concentration of a single element in the iron bag, the concentration of multiple elements in the iron bag, or the concentration of all elements in the iron bag.

[0077] Step 203: Arrange and combine the N defective iron bags to obtain M first combinations of the N defective iron bags.

[0078] When N is 3, after permuting and combining N defective iron bags, the first combination {(1,2),(1,3),(2,3),(1,2,3)} is obtained.

[0079] Alternatively, by permuting and combining the N defective iron bags, the Stirling number of the second kind can be used to determine the M first combinations of the N defective iron bags.

[0080] For example, when N is 3, and the corresponding iron bags are numbered 1, 2, and 3, determine the M first combinations of the 3 defective iron bags:

[0081] {[(1),(2,3)],[(1,3),(2)],[(1,2),(3)],[(1),(2),(3)],[(1,2,3)]}.

[0082] Step 204: For each first combination, determine the second parameter information of each element in the first combination based on the first parameter information.

[0083] In one example, when the first combination is (1,2), the second parameter information in the first combination is determined based on the first parameter information of iron bag 1 and the first parameter information of iron bag 2.

[0084] In another example, when M first combinations are determined based on the second type of Stirling number, when the first combination is [(1), (2,3)], the second parameter information of each element in the first combination is determined based on the first parameter information of the 1 iron bag, the first parameter information of the 2 iron bag and the parameter information of the 3 iron bag. That is, the second parameter information of element (1) in the first combination and the second parameter information of element [(2,3)] in the first combination.

[0085] The second parameter information includes the second weight information, second temperature information, and second concentration information of each element in the first combination.

[0086] Specifically, taking the first combination [(1),(2,3)] as an example, the first parameter information of the first element (1) needs to be determined based on the first parameter information of the iron ladle 1. The first weight information of the iron ladle 1 is m1, the first concentration information is c1, and the first temperature information is t1. Then, in the second parameter information of the first element (1), the second weight information is m1, the second concentration information is c1, and the second temperature information is t1.

[0087] Determine the second parameter information of the second element (2,3) in the first combination [(1),(2,3)], determine the first parameter information of iron bag 2 and the first parameter information of iron bag 3, and determine the second parameter information of the element based on the first parameter information of iron bag 2 and iron bag 3.

[0088] Specifically, the first weight information of ladle 2 is m2, the first concentration information is c2, and the first temperature information is t2; the first weight information of ladle 3 is m3, the first concentration information is c3, and the first temperature information is t3. Therefore, the second weight information of element (2,3) is m2 + m3, and the second concentration information is... The second temperature information is

[0089] Step 205: Calculate the score for each first combination based on the second parameter information of each element in each first combination.

[0090] Determine the weight information and standard parameter information corresponding to each second parameter information, wherein the second weight information corresponds to the first weight information, the second temperature information corresponds to the second weight information, the second concentration information corresponds to the third weight information, the second weight information corresponds to the standard weight information, the second temperature information corresponds to the standard temperature information, and the second concentration information corresponds to the standard concentration information; based on each second parameter information, the corresponding weight information, and the standard parameter information, calculate the first score of each element; calculate the average of multiple first scores as the score of each first combination.

[0091] Calculate the first fraction of each element using the following formula:

[0092]

[0093] Where h1 is the first weight information, h2 is the second weight information, h3 is the third weight information, and m is the second weight information of the element. 优 For standard weight information, t represents the second temperature information of the element. 优 Here is the standard temperature information, and c is the second concentration information. 优 This is standard concentration information.

[0094] Specifically, when the first combination is [(1),(2,3)], the first score of element (1) in the first combination is calculated using the above formula, the first score of element (2,3) in the first combination is calculated using the above formula, and the average of the two first scores is taken as the score of the first combination [(1),(2,3)].

[0095] Specifically: the first fraction of element (1) in the first combination:

[0096] h1 represents the first weight information, h2 represents the second weight information, and h3 represents the third weight information. The second weight information of element (1) in the first combination, m 优 For standard weight information, The second temperature information for element (1) in the first combination, This is the second concentration information for element (1) in the first combination. The first fraction of element (1) in the first combination.

[0097] The first fraction of the (2,3) element in the first combination:

[0098] h1 represents the first weight information, h2 represents the second weight information, and h3 represents the third weight information. For the second weight information of the (2,3) element in the first combination, m 优 For standard weight information, This provides the second temperature information for element (2,3) in the first combination. This provides the second concentration information for element (2,3) in the first combination. It is the first fraction of the (2,3) elements in the first combination.

[0099] Step 206: Sort each first group according to the score in descending order, and obtain the first target group with the first number of sorted scores for use in iron bag scheduling.

[0100] In one example, when the first combination (1,2) and (1,3) are the combinations with the highest scores among the M combinations, when the preset number is 2, the two combinations with the highest scores are obtained, and the first combination (1,2) and (1,3) are determined as the first target combination.

[0101] In another example, when the M first combinations are:

[0102] {[(1),(2,3)],[(1,3),(2)],[(1,2),(3)],[(1),(2),(3)],[(1,2,3)]}, the scores of the first combination [(1),(2,3)], the first combination [(1,3),(2)] and the first combination [(1,2),(3)] are ranked first. When the preset quantity is 3, the top 3 combinations are obtained and the above 3 combinations are determined as the first target combinations.

[0103] The dispatcher can choose from the above three primary objectives.

[0104] This application obtains N defective iron ladles and determines the first parameter information of each defective iron ladle; it then arranges and combines the N defective iron ladles to obtain M first combinations of the N defective iron ladles; for each first combination, based on the first parameter information, it determines the second parameter information of each element in the first combination, wherein the second parameter information includes the second weight information, second temperature information, and second concentration information of each element in the first combination; based on the second parameter information of each element in each first combination, it calculates the score of each first combination; it sorts the first combinations according to the score and obtains a preset number of first target combinations at the top of the sorted list for use in iron ladle scheduling. This application's embodiment calculates the first target combinations based on the defective iron ladles, thus enabling the generation of qualified iron ladles from the defective iron ladles without requiring additional processes to convert them into qualified iron ladles, reducing the number of processes. Furthermore, the algorithm-based determination of the first target combinations is more accurate than manual determination methods.

[0105] To further realize ladle scheduling, in another embodiment of this application, such as Figure 3 As shown, a ladle scheduling method based on molten iron composition is provided, which specifically includes the following steps:

[0106] Step 301: Merge the defective iron bags corresponding to the elements in each first target combination to obtain multiple first target iron bags.

[0107] In one example, the first target combination is (1,2) and (1,3). Iron bag 1 and iron bag 2 in (1,2) are fused together, and iron bag 1 and iron bag 3 in (1,3) are fused together to obtain the first target iron bag after the fusion of iron bag 1 and iron bag 2, and the first target iron bag after the fusion of iron bag 1 and iron bag 3.

[0108] In another example, by combining the first target combination [(1),(2,3)] as described above, the iron bags corresponding to each element can be mixed in proportion to obtain the mixed first target iron bag. For example, iron bag 1 is fused by 1 / 2, iron bag 2 is fused by 1 / 4, and iron bag 3 is fused by 1 / 4 to obtain the fused first target iron bag.

[0109] Step 302: Remove the defective iron bags corresponding to each element in each first target combination from the N defective iron bags to obtain multiple second target iron bags.

[0110] Specifically, if there are N defective iron bags (1,2,3,4,5,6,7), and the first target combination is [(1),(2,3)], then removing iron bags 1, 2, and 3 from the N defective iron bags yields iron bags 4, 5, and 6. That is, iron bags 4, 5, and 6 are the second target iron bags.

[0111] Step 303: Obtain multiple third target iron bags from each of the second target iron bags.

[0112] Among them, the weight information of the third target iron bag meets the first preset condition.

[0113] For example, a qualified iron bag is selected from iron bags 4, 5, and 6 and designated as the third target iron bag. For instance, if the weights of iron bags 4, 5, and 6 are all qualified, then iron bags 4, 5, and 6 are designated as the third target iron bag.

[0114] Step 304: Obtain multiple fourth target iron bags from each of the first target iron bags and each of the third target iron bags.

[0115] Among them, the concentration information of the fourth target iron bag does not meet the second preset condition.

[0116] It should be noted that the second preset condition is that the concentrations of the first and third target iron packages are not up to standard.

[0117] For example, from the fused iron bags 4, 5, and 6, iron bags with unqualified concentration information are identified as iron bags 4, 5, and 6, and iron bags 4, 5, and 6 are determined as the fourth target iron bag.

[0118] Step 305: Determine the third parameter information for each fourth target iron bag.

[0119] Step 306: Arrange and combine each of the fourth target iron bags to obtain the second combination of each fourth target iron bag.

[0120] By arranging and combining iron bags 4, 5, and 6, we can obtain the second combination (4,5), (5,6), (4,6), and (4,5,6).

[0121] Alternatively, based on the Stirling number of the second kind, we can obtain:

[0122] The second combination of {[(4),(5,6)],[(4,6),(5)],[(4,5),(6)],[(4),(5),(6)],[(4,5,6)]}.

[0123] Step 307: For each second combination, based on the third parameter information, determine the fourth parameter information of each element in the second combination.

[0124] Taking the second combination [(4),(5,6)] as an example, determining the third parameter information of the first element (4) requires determining it based on the third parameter information of the ladle 4. The third weight information of the ladle 4 is m4, the third concentration information is c4, and the third temperature information is t4. Therefore, the fourth parameter information of the first element (4) is m5, the fourth concentration information is c5, and the fourth temperature information is t5. To determine the fourth parameter information of the second element (5,6) in the second combination [(4),(5,6)], the third parameter information of ladle 5 and ladle 6 must be determined. Based on the third parameter information of ladle 5 and ladle 6, the fourth parameter information of this element is then determined.

[0125] Specifically, the third weight information of ladle 5 is m6, the third concentration information is c6, and the third temperature information is t6; the third weight information of ladle 6 is m7, the third concentration information is c7, and the third temperature information is t7. Therefore, the fourth weight information of element (5,6) is m6+m7, and the fourth concentration information is... The fourth temperature information is

[0126] Step 308: Calculate the score for each second combination based on the fourth parameter information of each element in each second combination.

[0127] Determine the weight information and standard parameter information corresponding to each fourth parameter information, where the fourth temperature information corresponds to the fourth weight information, the fourth concentration information corresponds to the fifth weight information, the fourth temperature information corresponds to the standard temperature information, and the fourth concentration information corresponds to the standard concentration information; based on each fourth parameter information, the corresponding weight information and standard parameter information, calculate the second score of each element in the second combination; calculate the average of multiple second scores as the score of each second combination.

[0128] Calculate the first fraction of each element using the following formula:

[0129] Second score

[0130] Where h4 is the fourth weighting information, h5 is the fifth weighting information, and t is the fourth temperature information of the element. 优 The standard temperature information is c, and the fourth concentration information is c. 优 This is standard concentration information.

[0131] Specifically, when the second combination is [(4),(5,6)], the second score of element (4) in the second combination is calculated using the above formula, the second score of element (5,6) in the second combination is calculated using the above formula, and the average of the two second scores is taken as the score of the second combination [(4),(5,6)].

[0132] Step 309: Sort the scores of each second group in descending order, and obtain the preset number of second target groups at the top of the sorted list for use in iron bag scheduling.

[0133] After step 309, if there are still unqualified ladles among the ladles corresponding to the elements of the second target combination, the unqualified ladles can be sent directly to the foundry, or the ladles corresponding to each element in the second target combination can be mixed in proportion, and the qualified ladles can be mixed with the unqualified ladles. Then, through steps 301 to 309, the unqualified ladles can be processed into qualified ladles.
