Description

Technical Field

[0001] This application relates to the field of industrial control technology, and in particular to a method and related equipment for adjusting carbon content. Background Technology

[0002] The quality of sintered ore plays a crucial role in the stability of subsequent blast furnace smelting. The carbon content has a significant impact on the quality of sintered ore, and excessively high carbon content can easily cause hidden dangers in production.

[0003] Most current sintering processes use a single batching process, and the primary batching chamber is very far from the sintering machine. Foreign objects stuck in the weighing head and sensors of the primary batching belt electronic scale cause the zero point of the electronic scale to drift significantly. As a result, the staff can only detect the carbon content of the sinter material exceeding the standard in a delayed manner. Therefore, it is impossible to adjust the carbon content of the sinter material in a timely manner, which leads to a decline in the quality of the sinter. Summary of the Invention

[0004] This application provides a method and related equipment for adjusting carbon content, which can quickly adjust the carbon content in sintered materials, thereby improving the output quality of sintered ore.

[0005] The first aspect of this application provides a method for adjusting carbon content in a sintering process, the sintering process including a primary batching process and a secondary batching process, wherein a secondary batching chamber for performing the secondary batching process is closer to the sintering machine than a primary batching chamber for performing the primary batching process, the method for adjusting carbon content comprising:

[0006] Obtain the actual index value and target index value of the sinter, wherein the actual index value is related to the carbon content of the sinter.

[0007] If the first difference between the actual index value and the target index value is greater than a first preset threshold, the secondary target carbon content in the secondary batching process is adjusted so that the first difference is less than or equal to a second preset threshold, wherein the second preset threshold is less than the first preset threshold.

[0008] In some embodiments, the method for adjusting the carbon content further includes:

[0009] If the first difference between the actual index value and the target index value is less than or equal to the first preset threshold and greater than the second preset threshold, the target carbon content in the first batching process is adjusted so that the first difference is less than or equal to the second preset threshold, wherein the second preset threshold is less than the first preset threshold.

[0010] In some embodiments, the primary batching process includes: metal material, flux, and fuel.

[0011] In some embodiments, the secondary batching process includes recycled ore.

[0012] The returned ore includes self-produced returned ore and / or blast furnace returned ore.

[0013] In some embodiments, after adjusting the secondary target carbon content in the secondary batching process to make the first difference less than or equal to a second preset threshold when the first difference between the actual index value and the target index value is greater than a first preset threshold, the carbon content adjustment method further includes:

[0014] The target carbon content is adjusted, wherein the adjustment amount is related to the first difference, and the adjustment amount is used to characterize the magnitude of the adjustment of the target carbon content.

[0015] Keeping the adjusted secondary target carbon content unchanged, the ratio of the sintered material to the return ore in the secondary batching process is adjusted according to the second difference between the adjusted primary target carbon content and the adjusted secondary target carbon content, so that the ratio is restored to the preset ratio.

[0016] In some embodiments, adjusting the primary target carbon content includes:

[0017] Obtain the actual amount of carbon-containing ingredients used in the primary batching process, wherein the carbon-containing ingredients belong to the primary batching process;

[0018] If the actual dosage is inconsistent with the target dosage, the actual dosage is adjusted so that the absolute value of the third difference between the actual dosage and the target dosage is within a preset range, wherein the target dosage is related to the adjustment amount.

[0019] In some embodiments, adjusting the primary target carbon content includes:

[0020] According to the adjustment amount, the target carbon content is adjusted once every 2%, wherein the portion less than 2% is determined as 2%, and the time interval between each adjustment is greater than or equal to 1 hour.

[0021] A second aspect of this application provides a carbon content adjustment device for a sintering process, the sintering process including a primary batching process and a secondary batching process, wherein the secondary batching chamber for performing the secondary batching process is closer to the sintering machine than the primary batching chamber for performing the primary batching process, and the carbon content adjustment device includes:

[0022] An acquisition unit is used to acquire the actual index value and the target index value of the sinter, wherein the actual index value is related to the carbon content of the sinter.

[0023] The adjustment unit is used to adjust the secondary target carbon content in the secondary batching process when the first difference between the actual index value and the target index value is greater than a first preset threshold, so that the first difference is less than or equal to a second preset threshold, wherein the second preset threshold is less than the first preset threshold.

[0024] A third aspect of this application provides an electronic device comprising at least one processor and at least one memory connected to the processor, wherein the processor is configured to invoke program instructions in the memory to execute the carbon content adjustment method described in any one aspect above.

[0025] A fourth aspect of this application provides a storage medium including a stored program, wherein, when the program is executed, the device on which the storage medium is located executes the carbon content adjustment method described in any one of the first aspects.

[0026] In summary, this application provides a method for adjusting carbon content in a sintering process, which includes a primary batching process and a secondary batching process. The secondary batching chamber for performing the secondary batching process is closer to the sintering machine than the primary batching chamber for performing the primary batching process. The method for adjusting carbon content includes: obtaining an actual index value and a target index value for the sinter, wherein the actual index value is related to the carbon content of the sinter; and adjusting the secondary target carbon content in the secondary batching process when a first difference between the actual index value and the target index value is greater than a first preset threshold, so that the first difference is less than or equal to a second preset threshold, wherein the second preset threshold is less than the first preset threshold. In existing sintering processes, only a single batching process is configured, and the primary batching chamber is far from the sintering machine. In actual production, it takes more than two hours for the sintering material from the primary batching chamber to reach the sintering machine via conveyor belt or other transport devices. Therefore, when on-site personnel detect that the actual value of the carbon content-related indicators of the sinter deviates too much from the target value, which may even affect production safety, adjusting the carbon content of the sintering material through the primary batching process is severely delayed. At the same time, since there is only one opportunity to adjust the batching, there is a possibility that the operator may enter the wrong proportion when adjusting the material ratio, resulting in the sintering material quality not meeting the standards. The carbon content adjustment method proposed in this application involves setting up a secondary batching process based on the primary batching process. The secondary batching chamber is located closer to the sintering machine than the primary batching chamber. When on-site personnel detect that the actual carbon content-related index value of the sinter deviates significantly from the target index value (i.e., reaches the aforementioned first preset threshold), they can adjust the secondary target carbon content in the secondary batching process based on the first difference between the actual and target index values. This ensures that the carbon content of the sinter produced from the adjusted sinter is less than the aforementioned first threshold. With two preset thresholds, the carbon content of the sinter after the secondary batching process in the secondary batching chamber will reach the adjusted target carbon content. Moreover, since the secondary batching chamber is closer to the sintering machine than the primary batching chamber, the adjustment lag of the carbon content of the sinter is lower. Furthermore, by setting up the secondary batching process on the basis of the primary batching process, the secondary batching process can compensate for errors made by operators in the primary batching process. Therefore, the carbon content adjustment method provided in this application can reduce the defect rate of sintered ore.

[0027] Correspondingly, the carbon content adjustment device, electronic device, and computer-readable storage medium provided in this application also have the aforementioned technical effects. Attached Figure Description

[0034] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus. The technical solutions of the embodiments of this application will now be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.

[0035] The first aspect of this application provides a method for adjusting carbon content in a sintering process, the sintering process including a primary batching process and a secondary batching process, wherein the secondary batching chamber for performing the secondary batching process is closer to the sintering machine than the primary batching chamber for performing the primary batching process.

[0036] It should be noted that the sintering process refers to the process of mixing various powdered iron-containing raw materials (sintering materials), adding appropriate amounts of fuel and flux, adding appropriate amounts of water, mixing and pelletizing them, and then subjecting the materials to a series of physicochemical changes on sintering equipment to bind the mineral powder particles into blocks (sintered ore). The sintering equipment is such as the sintering machine in this application.

[0037] The method provided in this application embodiment is mainly for rapidly adjusting the carbon content in sintered material. The sintering process includes a primary batching process and a secondary batching process. The secondary batching chamber, which performs the secondary batching process, is closer to the sintering machine than the primary batching chamber, which performs the primary batching process. The sintered material needs to pass through the primary and secondary batching processes sequentially before entering the sintering machine for processing to produce sintered ore. During the primary batching process in the primary batching chamber, a primary target carbon content is established. A certain amount of primary materials is added during the primary batching process to achieve this target carbon content. After the primary batching process, the sintered material can enter the secondary batching chamber via a conveyor belt or other transport equipment. A secondary batching process is then performed in the secondary batching chamber, where a secondary target carbon content is established. This secondary batching process involves adding secondary materials to the sintered material to achieve the secondary target carbon content.

[0038] The following describes a method for adjusting carbon content proposed in an embodiment of this application.

[0039] Figure 1 A schematic flowchart illustrating a method for adjusting carbon content provided in this application embodiment; as follows: Figure 1 As shown, methods for adjusting carbon content include:

[0040] S110, obtain the actual index value and target index value of sinter, wherein the actual index value is related to the carbon content of the sinter.

[0041] For example, when sintered materials that have undergone a primary batching process and a secondary batching process are fed into a sintering machine, and sintered ore is generated after processing, the content of elements or compounds in the sintered ore is tested to obtain its actual index value. The actual index value of the sintered ore includes the actual ferrous content of the sintered ore produced by the sintering machine, and the target index value refers to the index content corresponding to the qualified conditions of the sintered ore.

[0042] It should be noted that the selected index value can also be the content value of other elements or compounds, as long as it is related to the carbon content in the sinter.

[0043] S120, when the first difference between the actual index value and the target index value is greater than the first preset threshold, the secondary target carbon content in the secondary batching process is adjusted so that the first difference is less than or equal to the second preset threshold, wherein the second preset threshold is less than the first preset threshold.

[0044] For example, the aforementioned first preset threshold and second preset threshold can be understood as deviations from the target indicator value. A second preset threshold being less than the first preset threshold indicates that when the deviation is too large and reaches the first preset threshold, the carbon content of the sinter is severely excessive and requires immediate adjustment. Conversely, when the carbon content of the sinter is less than the second preset threshold, it indicates that the current carbon content of the sinter meets the requirements.

[0045] If the difference between the actual index value and the target index value of the sinter is greater than the first preset threshold, the secondary target carbon content in the secondary batching process is adjusted so that the carbon content of the sintering material after the secondary batching process changes, thereby changing the carbon content of the sintering produced by the sintering machine.

[0046] In existing sintering processes, only a single batching process is configured, and the primary batching chamber is far from the sintering machine. In actual production, it takes more than two hours for the sintering material from the primary batching chamber to reach the sintering machine via conveyor belt or other transport devices. Therefore, when on-site personnel detect that the actual value of the carbon content-related indicators of the sinter deviates too much from the target value, which may even affect production safety, adjusting the carbon content of the sintering material through the primary batching process is severely delayed. At the same time, since there is only one opportunity to adjust the batching, there is a possibility that the operator may enter the wrong proportion when adjusting the material ratio, resulting in the sintering material quality not meeting the standards. The carbon content adjustment method proposed in this application embodiment sets up a secondary batching process based on the primary batching process. The secondary batching chamber is closer to the sintering machine than the primary batching chamber. When on-site personnel detect that the actual index value related to carbon content in the sinter deviates too much from the target index value, i.e., reaches the aforementioned first preset threshold, they can adjust the secondary target carbon content in the secondary batching process based on the first difference between the actual and target index values. This ensures that the carbon content of the sinter produced from the adjusted sinter is less than the aforementioned first threshold. With two preset thresholds, the carbon content of the sinter after the secondary batching process in the secondary batching chamber will reach the adjusted target carbon content. Moreover, since the secondary batching chamber is closer to the sintering machine than the primary batching chamber, the adjustment lag of the carbon content of the sinter is lower. Furthermore, by setting up a secondary batching process based on the primary batching process, it is possible to compensate for errors caused by operators adding incorrect materials during the primary batching process. Therefore, the carbon content adjustment method provided in this application embodiment can reduce the defect rate of sintered ore.

[0047] According to some embodiments, the above-mentioned method for adjusting carbon content further includes: adjusting the target carbon content in a primary batching process when the first difference between the actual index value and the target index value is less than or equal to a first preset threshold and greater than a second preset threshold, so that the first difference is less than or equal to the second preset threshold, wherein the second preset threshold is less than the first preset threshold.

[0048] For example, if the first difference between the actual index value of the sinter and the target index value is less than or equal to the first preset threshold and greater than the second preset threshold, it indicates that the carbon content of the current sinter does not meet the standard but the deviation is not particularly serious. Therefore, it can be adjusted through a batching process to make the carbon content adjustment of the sinter smoother.

[0049] According to some embodiments, a primary batching process includes: metal material, flux, and fuel.

[0050] For example, the aforementioned metal materials may include magnetic powder, foreign ore, solid waste, etc.; the aforementioned flux may include limestone powder, dolomite powder, high magnesium hydrate, quicklime, etc.; and the aforementioned fuel may include coke powder, coal, etc.

[0051] According to some embodiments, the secondary batching process includes return ore, wherein the return ore includes self-produced return ore and / or blast furnace return ore.

[0052] For example, the aforementioned self-produced return ore refers to the sintered ore that is not up to standard during the sintering process, and the aforementioned blast furnace return ore refers to the sintered ore, pellets, lump ore, and other unqualified semi-finished products that are not up to standard in terms of particle size before entering the blast furnace.

[0053] The concept of this application embodiment is to utilize the large difference between the carbon content of the returned ore and the carbon content of the sinter in the secondary batching process (the carbon content of the returned ore is about 0.02%, and the carbon content of the sinter is about 3.0%). The carbon content of the sinter is adjusted by adjusting the ratio between the returned ore and the secondary batching sinter.

[0054] In some examples, embodiments of this application provide a formula for calculating the carbon content of a sintering material, as shown below:

[0055]

[0056] Among them, C 混 C 返 C 燃 C 固废 Q represents the carbon content in sinter, return ore, fuel, and solid waste, respectively. 混 Q 返 Q 燃 Q 固废These represent the consumption of sintering materials, recycled ore, fuel, and solid waste, respectively.

[0057] According to some embodiments, when the first difference between the actual index value and the target index value is greater than a first preset threshold, the secondary target carbon content in the secondary batching process is adjusted so that the first difference is less than or equal to a second preset threshold. The carbon content adjustment method further includes:

[0058] The target carbon content is adjusted once, wherein the adjustment amount is related to the first difference, and the adjustment amount is used to characterize the magnitude of the adjustment of the target carbon content once.

[0059] Keeping the adjusted secondary target carbon content unchanged, the ratio of sintered material to return ore in the secondary batching process is adjusted according to the second difference between the adjusted primary target carbon content and the adjusted secondary target carbon content, so that the ratio is restored to the preset ratio.

[0060] For example, after adjusting the secondary target carbon content of the secondary batching process, considering that the production and consumption of return ore should be in a state of balance, and since adjusting the secondary target carbon content will lead to excessive (or insufficient) consumption of return ore, it is necessary to adjust it to the above-mentioned preset ratio. For example, if the ratio of sintered material to return ore before the adjustment of the return ore ratio is 7:3, then the preset ratio should be adjusted to 7:3.

[0061] To adjust the carbon content of the secondary target, the carbon content of the primary target is first adjusted. The adjustment amount is used to characterize the magnitude of the adjustment of the carbon content of the primary target and is related to the first difference. Specifically, it can be determined by the physical quality intelligent control system.

[0062] After adjusting the target carbon content once, the ratio of the sintered material to the return ore in the secondary batching process is adjusted according to the second difference between the adjusted target carbon content once and the adjusted secondary target carbon content, so that the ratio is restored to the preset ratio.

[0063] It should be noted that the adjusted secondary target carbon content is the carbon content of the sinter after the secondary batching process. At this point, the actual carbon content of the sinter produced after passing through the sintering machine meets the quality requirements. Therefore, there is no need to adjust the aforementioned secondary target carbon content; that is, the adjusted secondary target carbon content remains unchanged. Instead, the ratio of sinter to return ore in the secondary batching process is adjusted based on the second difference between the adjusted primary target carbon content and the adjusted secondary target carbon content, so that this ratio is restored to the preset proportion. This ensures that the consumption of sinter and return ore in the secondary batching process is at a suitable ratio, avoiding insufficient secondary batching supply or overflow problems due to excessive or insufficient return ore consumption.

[0064] According to some embodiments, adjusting the target carbon content includes:

[0065] Obtain the actual amount of carbon-containing ingredients used in a single batching process, wherein the carbon-containing ingredients belong to the single batching process;

[0066] When the actual dosage differs from the target dosage, the actual dosage is adjusted so that the absolute value of the third difference between the actual dosage and the target dosage is within a preset range, wherein the target dosage is related to the adjustment amount.

[0067] For example, adjusting the target carbon content in a primary batching process, and determining the target amount of carbon-containing ingredients in the primary batching, can be achieved using a physical quality intelligent control system. This system monitors the actual amount of carbon-containing ingredients in real time using a primary batching disc feeder and an electronic belt scale while simultaneously reducing or increasing the amount. If the actual amount differs from the target amount, the carbon-containing ingredients are adjusted so that the difference between the actual and target amounts is within a preset range. This prevents excessive adjustment of the primary target carbon content, which could increase the difficulty of adjusting the secondary batching process.

[0068] According to some embodiments, the above-described adjustment of the primary target carbon content includes:

[0069] The target carbon content is adjusted once every 2% of the adjustment amount, with any portion less than 2% being set at 2%. The time interval between each adjustment is greater than or equal to 1 hour.

[0070] It should be noted that after each adjustment of the target carbon content, the secondary batching can be adjusted once according to the above embodiment. After multiple adjustments, the ratio of sinter to return ore in the secondary batching can reach the preset ratio, thereby achieving a gradual transition between the ratio of primary and secondary batching.

[0071] For example, the adjustment amount is 7%, and the target carbon content is adjusted once for every 2%, with any part less than 2% determined as 2%, that is, it needs to be adjusted 4 times, and the time interval between each adjustment is greater than or equal to 1 hour.

[0072] The method for adjusting carbon content has been described above. The following describes the carbon content adjustment device in the embodiments of this application.

[0073] Please see Figure 2 This application describes one embodiment of a carbon content adjustment device in a sintering process, which includes a primary batching process and a secondary batching process. The secondary batching chamber for performing the secondary batching process is closer to the sintering machine than the primary batching chamber for performing the primary batching process. The adjustment device may include:

[0074] The acquisition unit 201 is used to acquire the actual index value and the target index value of the sinter, wherein the actual index value is related to the carbon content of the sinter.

[0075] The adjustment unit 202 is used to adjust the secondary target carbon content in the secondary batching process when the first difference between the actual index value and the target index value is greater than a first preset threshold, so that the first difference is less than or equal to a second preset threshold, wherein the second preset threshold is less than the first preset threshold.
