The actual water addition is adjusted according to the target water addition, improving the moisture control effect. Furthermore, the material types include flux types, dust collector ash types, and other types, where "other types" refers to types other than flux types and dust collector ash types.

[0017] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application. Attached Figure Description

[0018] Various other advantages and benefits will become apparent to those skilled in the art upon reading the following detailed description of preferred embodiments. The accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, the same reference numerals denote the same parts throughout the drawings. In the drawings: Figure 1 This is a flowchart of a method for controlling the moisture content of sintering mixtures provided in an embodiment of this application; Figure 2 This is a structural block diagram of a sintering mixture moisture control device provided in an embodiment of this application. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings. It should be understood that the embodiments of this disclosure and the specific features in the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations on the technical solutions of this application. Unless otherwise specified, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0020] Figure 1 This is a flowchart of a method for controlling the moisture content of a sintering mixture provided in an embodiment of this application, such as... Figure 1 As shown, the method includes: Step S110: Obtain the material type, feed amount and moisture coefficient of each material in the mixture.

[0021] The material types include flux types, dust collector ash types, and other types, with "other types" referring to types other than flux types and dust collector ash types. The mixture contains multiple materials, each belonging to a different material type.

[0022] In the embodiments of this application, the properties of different material types are different. Due to the differences in their particle size, moisture content, and hydrophilicity, the moisture requirements of each type of material during sintering are different. Therefore, this application classifies material types into flux type, dust removal ash type, and other types based on their properties. Flux type materials are materials mixed with clinker flux. Dust removal ash type materials are solid powdery waste collected from flue gas or air by dust removal equipment (such as bag filters, electrostatic precipitators, etc.). Other types of materials include high-return ore, calcined return ore, blended ore (or single-variety mineral powder), coke powder, limestone, and dolomite.

[0023] In this embodiment, the total amount of the mixture is controlled by controlling the amount of each material fed; that is, the total amount of material fed is the sum of the amounts of all materials fed. The moisture coefficient refers to the theoretical weight of water that needs to be added per unit weight of material during sintering. The moisture coefficient of each material can be detected through tests such as hydrophilicity. Finally, the material type and moisture coefficient of each material can be stored in a knowledge base.

[0024] Step S120: Determine the amount of water to be added per material for different material types based on the material type, feed rate, and moisture coefficient.

[0025] In this embodiment, for each material type, the amount of water added per material is determined based on the corresponding feed rate and moisture coefficient; that is, the amount of water required for sintering each material. Finally, the amount of water added per material for all materials can be obtained.

[0026] Step S130: Sum of the water addition amounts of all individual materials as the target water addition amount of the mixture.

[0027] The embodiments of this application determine the amount of water added to each material based on the material type, the amount of water added to each material, and the moisture coefficient. Then, the sum of the water added to all materials is calculated to obtain the total amount of water added to the mixture. This total amount of water added is used as the target amount of water added, rather than directly determining the total amount of water added to the mixture based on the total amount of water added to the mixture. This makes the target amount of water added more closely match the composition and content of various materials in the mixture.

[0028] Step S140: Adjust the actual amount of water added to the mixture according to the target amount of water added.

[0029] In this embodiment, adjusting the actual water addition to the mixture based on the target water addition includes: if the actual water addition is less than the target water addition, and a first difference between the target water addition and the actual water addition is greater than a preset difference threshold, then the actual water addition is increased; if the actual water addition is greater than the target water addition, and a second difference between the actual water addition and the target water addition is greater than a preset difference threshold, then the actual water addition is decreased; if the actual water addition is equal to the target water addition, or the first difference is less than the difference threshold, or the second difference is less than the difference threshold, then the actual water addition is not adjusted. This ensures that the actual water addition is close to the target water addition, guaranteeing the effectiveness of moisture control.

[0030] In this embodiment of the application, the actual amount of water added to the mixture can be adjusted according to the target amount of water added using a PID (proportional-integral-derivative) algorithm.

[0031] Optionally, step S120 includes: Step S1201: If the material type is flux type, obtain the flux alkaline component content, flux coefficient and first compensation moisture coefficient of the flux type material, and determine the first single material water addition amount of the flux type material based on the feeding amount, moisture coefficient, flux alkaline component content, flux coefficient and first compensation moisture coefficient.

[0032] In this embodiment, the flux type material includes clinker flux, which contains alkaline components that require moisture during sintering. The alkaline components include calcium oxide and magnesium oxide.

[0033] The flux coefficient refers to the amount of flux (usually limestone or quicklime) required per unit weight of the main iron-containing raw material (such as iron ore) in the sintering batch to obtain sinter with a specified basicity. The first compensating moisture coefficient refers to the amount of additional water required per unit weight of dry material to achieve optimal granulation and permeability of the flux-type material.

[0034] Therefore, based on the material feed rate, moisture coefficient, basic component content of the flux, flux coefficient, and first compensation moisture coefficient, the first single-material water addition amount of the flux type can be determined.

[0035] Optionally, step S1201 includes: The first step is to determine the first theoretical water addition rate of the flux type based on the moisture coefficient and the content of basic components in the flux.

[0036] In this embodiment, the first theoretical water addition rate is the ratio of the theoretically required amount of water to the amount of material fed during sintering for flux-type materials. The parameters affecting the first theoretical water addition rate of flux-type materials are the moisture coefficient and the content of alkaline components in the flux. The content of alkaline components in the flux can be a percentage, so the first theoretical water addition rate of flux-type materials can be determined based on the moisture coefficient and the content of alkaline components in the flux.

[0037] In this embodiment, if the basic components of the flux include calcium oxide and magnesium oxide, the first theoretical water addition rate of the flux type material can be calculated according to formula (1): α1=(CaO×18 / 56+MgO×18 / 40)×K1 formula (1); Where α1 represents the first theoretical water addition rate, CaO represents the calcium oxide content in the clinker flux, MgO represents the magnesium oxide content in the clinker flux, and K1 represents the moisture coefficient.

[0038] The second step is to determine the first compensation water addition rate of the flux type material based on the content of the basic components of the flux, the flux coefficient, and the first compensation moisture coefficient.

[0039] In this embodiment, to achieve optimal granulation and permeability, a compensation water amount is required for flux-type materials. The first compensation water addition rate is the ratio of the compensation water amount required for sintering of the flux-type material to the amount of material fed. The parameters affecting the first compensation water addition rate of the flux-type material are the flux basic component content, the flux coefficient, and the first compensation water coefficient, which is pre-calibrated for flux-type materials. Therefore, the first compensation water addition rate of the flux-type material can be determined based on the flux basic component content, the flux coefficient, and the first compensation water coefficient.

[0040] Optionally, the content of the basic components of the flux includes the calcium oxide content, and the second step includes: Calculate the first product of flux coefficient and calcium oxide content; calculate the first difference between flux coefficient and the first product; calculate the sum of the first difference and a preset first constant; calculate the first ratio of the first product to the sum; and determine the first compensation water addition rate of the flux type material based on the second product of the first ratio and the first compensation moisture coefficient.

[0041] In this embodiment, since calcium oxide is the main component requiring compensation water, the first compensation water addition rate of the flux-type material can be calculated according to formula (2): β1=(K×K2×CaO) / (1+KK×CaO) formula (2); Where β1 represents the first compensation water addition rate, K2 represents the first compensation moisture coefficient (range 0-1), K represents the flux coefficient (range 0.32-0.6), and the first constant is 1.

[0042] According to formula (2), the first product is K×CaO, the first difference is KK×CaO, the sum is 1+KK×CaO, the first ratio is (K×CaO) / (1+KK×CaO), the second product is K2×(K×CaO) / (1+KK×CaO), and then the second product is used as the first compensation water addition rate.

[0043] In this embodiment of the application, the second product can also be modified according to the properties of the flux type material, and the modified second product can be used as the first compensation water addition rate.

[0044] The third step is to use the sum of the theoretical water addition rate and the compensated water addition rate as the first total water addition rate for flux-type materials.

[0045] In the embodiments of this application, the sum of the theoretical water addition rate and the compensated water addition rate can be directly used as the first total water addition rate of the flux-type material.

[0046] Step 4: Multiply the first total water addition rate by the amount of material fed, and use the first single-material water addition amount as the flux-type material.

[0047] In this embodiment of the application, the first single-item water addition amount of the flux-type material can be calculated according to formula (3): Q 水1 =Q 料 ×[(CaO×18 / 56+MgO×18 / 40)×K1+(K×K2×CaO) / (1+KK×CaO)] formula (3); Where Q represents the material feed rate, Q 水1 This indicates the amount of water added for the first batch of materials.

[0048] According to formula (3), the first single-material water addition amount of all flux types in the mixture can be calculated.

[0049] Step S1202: If the material type is dust removal ash, obtain the first saturated moisture and the second compensated moisture coefficient of the dust removal ash material, and determine the second single-material water addition amount of the dust removal ash material based on the feeding amount, moisture coefficient, first saturated moisture and second compensated moisture coefficient.

[0050] In this embodiment, the dust-collecting ash type material absorbs a large amount of moisture during sintering. However, to achieve optimal granulation and air permeability, moisture compensation is required using a second moisture compensation coefficient. This second moisture compensation coefficient is pre-calibrated for the dust-collecting ash type material and ranges from 0 to 1. The first saturated moisture is the ratio of the maximum amount of water that the dust-collecting ash type material can hold through physical adsorption (such as surface adsorption and capillary action) to the total weight of the material when it reaches a saturated moisture state. The saturated moisture state is the state in which the material holds the maximum amount of water through physical adsorption (such as surface adsorption and capillary action). Therefore, the sum of the maximum amount of water and the weight of the dry material before water absorption is equal to the weight of the material in the saturated moisture state, i.e., the weight of the wet material. Thus, the first saturated moisture is the ratio of the maximum amount of water to the weight of the wet material, and the ratio of dry material to wet material is the percentage of dry material. The first saturated moisture coefficient ranges from 0 to 1.5.

[0051] Therefore, the amount of water added to the second batch of dust removal ash can be determined based on the parameters that affect the amount of water added to the second batch, namely, the amount of material fed, the moisture coefficient, the first saturated moisture content, and the second compensated moisture coefficient.

[0052] Optionally, step S1202 includes: Step 5: The product of the first saturated moisture content and the second moisture coefficient is taken as the second theoretical water addition rate of the dust removal ash type material.

[0053] In the embodiments of this application, the first saturated moisture content and the moisture coefficient mainly affect the theoretical water addition amount of the dust removal ash type material. Therefore, the second product of the first saturated moisture content and the moisture coefficient can be directly used as the second theoretical water addition rate α2 of the dust removal ash type material.

[0054] Step 6: Based on the second ratio of the first saturated moisture content to the dry material ratio, and the second compensation moisture coefficient, determine the second compensation water addition rate of the dust removal ash type material. The dry material ratio is the second difference between the preset second constant and the first saturated moisture content.

[0055] Among them, the second constant is 1, the first saturated moisture is h, and the dry material ratio is 1-h.

[0056] In this embodiment, the first saturated moisture content and the second compensation moisture coefficient affect the amount of compensation water added to the dust-collecting ash type material. Therefore, the second compensation water addition rate can be determined based on the first saturated moisture content and the second compensation moisture coefficient.

[0057] Optional, step six includes: Calculate the second ratio of the first saturated moisture content to the dry material content; multiply the second ratio by the third product of the second compensation moisture coefficient as the second compensation water addition rate for the dust removal ash type material.

[0058] Specifically, the second compensation water addition rate can be calculated according to formula (4): β2 = K2×h / (1-h)Formula (4); Where K2 represents the second moisture compensation coefficient. The second ratio is h / (1-h), and the third product is K2×h / (1-h).

[0059] In this embodiment of the application, the third product can also be modified according to the properties of the material of the dust removal ash type, and the modified third product can be used as the second compensation water addition rate.

[0060] Step 7: The sum of the second theoretical water addition rate and the second compensated water addition rate is taken as the second total water addition rate of the dust removal ash type material.

[0061] In this embodiment of the application, the sum of the second theoretical water addition rate and the second compensated water addition rate can be directly used as the second total water addition rate.

[0062] Step 8: Multiply the amount of material fed into the second total water addition rate as the second single-material water addition amount for the dust removal ash type of material.

[0063] In this embodiment of the application, the amount of water added to the second single material can be calculated according to formula (5): Q 水2 =Q 料 ×[h×K1+K2×h / (1-h)] formula (5); Q 水2 This indicates the amount of water added for the second batch of materials.

[0064] Therefore, the second single-material water addition amount of all dust removal ash types in the mixture can be calculated according to formula (5).

[0065] Step S1203: If the material type is other types, obtain the inherent moisture and second saturated moisture of the other types of materials, and determine the third single-material water addition amount of the other types of materials based on the feed amount, moisture coefficient, inherent moisture and second saturated moisture.

[0066] Here, the inherent moisture content refers to the total moisture contained in the other types of materials, expressed as a percentage; the second saturated moisture content is the ratio of the maximum amount of water that the other types of materials can hold through physical adsorption (such as surface adsorption and capillary action) to the total weight of the materials when they reach saturated moisture content. The value of the second saturated moisture content coefficient ranges from 0 to 1.5.

[0067] In this embodiment, other types of materials do not require water compensation through a moisture coefficient during sintering. Therefore, the third single-material water addition amount for other types of materials can be determined directly based on the feed amount, moisture coefficient, inherent moisture content, and second saturated moisture content.

[0068] Optionally, step S1203 includes: The third difference between the second saturated moisture content and the inherent moisture content is used as the required moisture content for other types of materials; the fourth product of the feed amount, required moisture content, and moisture coefficient is used as the third single-material water addition amount for other types of materials.

[0069] In this embodiment of the application, the amount of water added to the third single material can be calculated according to formula (6): Q 水3 =Q 料 Formula (6) ×(h-h0)×K1; Among them, Q 水3 This indicates the amount of water added to the third batch of materials, and h0 indicates the moisture content of the materials themselves.

[0070] Therefore, the third difference is h - h0, and the fourth product is Q. 料 ×(h-h0)×K1.

[0071] Therefore, the third single-material water addition amount for all other types of materials in the mixture can be calculated according to formula (6).

[0072] In the embodiments of this application, when the material type, the amount of material fed, or the composition of the mixture changes, the target amount of water added to the mixture changes accordingly, thereby making the moisture control effect based on the target amount of water added better.

[0073] For example, the feed rate, flux coefficient, moisture coefficient, compensated moisture coefficient (including the first compensated moisture coefficient and the second compensated moisture coefficient), inherent moisture, saturated moisture, calcium oxide content, and magnesium oxide content of various materials in the mixture are shown in Table 1 below: Table 1

[0074] According to formulas (3), (5) and (6), the water addition amount of each material can be calculated, and the sum of the water addition amounts of all materials is 49.66t / h.

[0075] Based on the same concept, this invention also provides a moisture control device for sintering mixtures. Figure 2 This is a structural block diagram of a sintering mixture moisture control device provided in an embodiment of this application, as shown below.
