Description

Technical Field

[0001] This invention relates to the field of ironmaking technology, and in particular to a parametric design method and apparatus for a four-channel blast furnace cooling wall. Background Technology

[0002] Cast iron cooling wall structures, as the main blast furnace coolers, can be divided into smooth cooling walls, brick-lined cooling walls, and C-type cooling walls. These three structures are suitable for different parts of the blast furnace. In different blast furnace designs, the blast furnace size varies, and therefore the size of the cooling walls used also varies, which increases the workload for designers. Summary of the Invention

[0003] In view of the above problems, the present invention provides a parametric design method and apparatus for a four-channel blast furnace cooling wall, which can reduce the amount of repetitive work in engineering and improve efficiency.

The cooling wall body, water pipe boss, and bolt boss in the initial parameter model are subjected to union processing. Then, based on the cooled wall body after union processing, the difference processing is performed with the cooling water pipe, cast-in nut, protective sleeve, and lifting lug. According to the design requirements, the cooling wall body is cut with dovetail groove and rounded corners. The cooling water pipe and protective sleeve are shelled. The cast-in nut is drilled and threaded to obtain the optimized parameter model. Create an input form for the original design parameters, and categorize and list the target high-frequency modification parameters such as cooling wall dimensions and cooling water pipe layout parameters in the input form.

Use the lofting tool to draw the sleeve entity with the cavity retained, forming the initial geometric model of 8 independent protective sleeves.

[0009] Optionally, the steps of the thermal steady-state analysis include: The system simulates the heat flux density distribution of the cooling wall and the temperature gradient in different regions during blast furnace operation. It calculates the thermal stress and strain values ​​of the cooling wall body and its components, and outputs an analysis report on the location of high-temperature regions and stress concentration points, which serves as the basis for adjusting pipe diameter parameters.

[0010] According to a second aspect of the present invention, a parametric design device for a four-channel blast furnace cooling wall is provided, characterized in that it comprises: The determination module is used to determine the original design parameters based on the design requirements regarding the blast furnace volume and furnace structure. The original design parameters include at least the number of cooling wall blocks, the outer diameter of the water pipes, the wall thickness, and the spacing. A new module is created to create a new part module and import the original design parameters. The original design parameters are used as independent variables to construct associated new parameters. Based on the constraint relationship between the original design parameters and the new parameters, initial geometric models of the cooling wall body, cooling water pipe, water pipe boss, bolt boss, cast-in nut, protective sleeve, and lifting lug are created respectively as the initial parameter models of the four-channel blast furnace cooling wall. The processing module is used to perform union processing on the cooling wall body, water pipe boss, and bolt boss in the initial parameter model. Then, based on the cooled wall body after union processing, it performs difference processing on the cooling water pipe, cast-in nut, protective sleeve, and lifting lug. According to the design requirements, the cooling wall body is cut with dovetail groove and rounded corners. The cooling water pipe and protective sleeve are shelled. The cast-in nut is drilled and threaded to obtain the optimized parameter model. A module is created to generate an input form for the original design parameters. Target high-frequency modification parameters, such as cooling wall dimensions and cooling water pipe layout parameters, are categorized and included in the input form. Parameter values ​​are modified through the input form to trigger an update of the optimization parameter model.

The adjustment module is used to adjust the cooling water pipe layout and pipe diameter parameters according to the performance evaluation results to obtain the target parameter model.

[0011] Optionally, the target platform is the Workbench platform.

[0014] The above-described one or more technical solutions in the embodiments of this specification have at least the following technical effects: This specification provides a parametric design method and apparatus for a four-channel blast furnace cooling wall. Based on the design requirements of the blast furnace volume and structure, original design parameters are determined, including the number of cooling wall blocks, the number of cooling water pipes, the outer diameter of the water pipes, the wall thickness, and the spacing. A new parts module is created, importing the original design parameters and constructing associated new parameters using these parameters as independent variables. Based on the constraint relationship between the original and new parameters, initial geometric models of the cooling wall body, cooling water pipes, water pipe bosses, bolt bosses, cast-in nuts, protective sleeves, and lifting lugs are created using extrusion, rotation, sweeping, and lofting tools, respectively, forming the initial geometric model of the four-channel blast furnace cooling wall. The initial parameter model is processed by performing a union operation on the cooling wall body, water pipe boss, and bolt boss. Then, based on the merged cooling wall body, a difference operation is performed on the cooling water pipe, cast-in nut, protective sleeve, and lifting lug. According to design requirements, the cooling wall body is cut with dovetail grooves and rounded corners. The cooling water pipe and protective sleeve are shelled, and the cast-in nut is drilled and threaded to obtain an optimized parameter model. An original design parameter input form is created, categorizing and listing the target high-frequency modification parameters such as cooling wall dimensions and cooling water pipe layout parameters. Modifying parameter values ​​through the form triggers automatic model updates. The optimized parameter model is imported into the Workbench platform to simulate the blast furnace heat load distribution, temperature field changes, and stress-strain, conducting thermal steady-state analysis and generating performance evaluation results. Based on the performance evaluation results, the cooling water pipe layout and diameter parameters are adjusted to obtain the target parameter model. In this way, it can be applied to the personalized design of blast furnace cooling walls with different volumes and furnace structures. It can automatically update the model and engineering drawings through parameter-driven operation, improve design efficiency and accuracy, and ensure the stable performance of the cooling wall under the high temperature conditions of the blast furnace.

[0027] Optionally, the steps of the thermal steady-state analysis include: The system simulates the heat flux density distribution of the cooling wall and the temperature gradient in different regions during blast furnace operation. It calculates the thermal stress and strain values ​​of the cooling wall body and its components, and outputs an analysis report on the location of high-temperature regions and stress concentration points, which serves as the basis for adjusting pipe diameter parameters.

[0028] To facilitate understanding and implementation by those skilled in the art, the following description is provided for this embodiment: First, determine the original design parameters and prepare the design calculation report. Specifically, the original design parameters can be determined based on the design requirements of the blast furnace volume and furnace structure (e.g., the height of the upper furnace shell inflection point, the radius of the lower furnace shell inflection point, the positioning dimensions of the cooling walls, etc.). The original design parameters include, but are not limited to, the basic parameters of the cooling walls, the parameters of the cooling water pipes, and the parameters of the auxiliary structures.

[0029] The basic parameters of the cooling wall include the number of cooling wall blocks, the height of the cooling wall (e.g., 1900mm), the thickness of the wall section (e.g., 235mm), the offset distance of the wall side (e.g., k1=15mm, k2=15mm), the distance between the outer surface generatrix of the cooling wall and the furnace shell generatrix (e.g., 30mm), the distance between the top of the furnace shell generatrix and the center of the blast furnace (e.g., 5500mm), the distance between the bottom of the furnace shell generatrix and the center of the blast furnace (e.g., 6000mm), the height of the furnace shell generatrix (e.g., 4000mm), and the distance between the bottom surface of the cooling wall and the bottom of the furnace shell generatrix and the center of the blast furnace (e.g., 15mm). Cooling water pipe parameters include the number of cooling water pipes (e.g., 4 independent channels), pipe outer diameter (e.g., 73mm), pipe wall thickness (e.g., 6.5mm), vertical positioning of inlet pipe, vertical positioning of outlet pipe, center distance of inlet pipe (e.g., 210mm), center distance of outlet pipe (e.g., 200mm), and distance between the centerline of the water pipe and the cold surface of the cooling wall (e.g., 80mm). Auxiliary structural parameters may include the thickness of the water pipe boss (e.g., 25mm), the major diameter of the water pipe boss (e.g., 160mm), the minor diameter of the bolt boss (e.g., 160mm for both the upper and lower rows), the distance from the boss to the top / bottom surface (e.g., 380mm), the dimensions of the dovetail groove for brick inlay (e.g., 80mm for the large end, 65mm for the small end, 75mm for the groove depth, 159mm for the groove spacing, and 12 grooves), and the installation and positioning of the lifting lugs. Based on the above parameters, a complete design calculation report is prepared to ensure that all parameters cover the design requirements of the cooling wall body, cooling water pipes, water pipe bosses, bolt bosses, cast nuts, protective sleeves, and lifting lugs, so as to provide data support for subsequent modeling.

[0030] Then, an initial parameter model of the four-channel blast furnace cooling wall was constructed.

[0031] Regarding the preparation of the software environment, the Inventor software's new part module can be used to import the previously determined original design parameters into the software parameter library. Using the original design parameters as independent variables, new parameters are constructed through constraints such as formula association and dimensional constraints (e.g., the coordinates of the center point of the water pipe boss, the taper of the bolt boss, and the layout path parameters of the protective sleeve). This ensures that all new parameters are linked with the original design parameters, reducing the number of independent variables and avoiding parameter conflicts.

[0032] The steps for creating the initial geometric model of each component may include: Cooling wall body: Draw the longitudinal view of the cooling wall, which can also be understood as drawing the longitudinal sketch of the cooling wall (including the wall outline and the reserved position of the dovetail groove). Rotate the sketch along the center line of the blast furnace by a preset angle (such as 9 degrees calculated based on the number of cooling wall blocks in the circumferential direction). Then, indent the left and right sides of the cooling wall body inward by a preset distance to form the basic structure of the cooling wall body with an arc, that is, the initial geometric model of the cooling wall body. Cooling water pipes: Determine the curved surface where the center line of the cooling water pipes is located in the cooling wall body, locate the plane, length and three-dimensional coordinates of the inlet water pipe and the outlet water pipe respectively, draw the water pipe solid with the cavity preserved by the sweep tool, and finally form the initial geometric model of 4 independent cooling water pipes. Water pipe boss: Determine the surface where the center point of the water pipe boss is located. Based on the position of the cooling water pipe and the center point of the boss, determine the center point of the boss plane. Draw a circular sketch on the center point plane (the diameter matches the major diameter of the water pipe boss). Extrude it to the outer side of the cooling wall body to form an independent boss solid. Repeat the operation to obtain the initial geometric model of 8 water pipe bosses. At the same time, determine the edge distance of the boss. Cut the boss with the edge distance that is too small (such as less than the design threshold of 15mm). Bolt boss: Determine the curved surface and horizontal plane where the center point of the bolt boss is located, draw a circular sketch on the tangent plane of the center point (the diameter matches the minor diameter of the bolt boss), and stretch it to the outer surface of the cooling wall body with a preset taper (such as 1:10) to form 4 independent bolt boss entities; Cast-in nut: Determine the plane where the cast-in nut is located by the center point of the bolt boss and the center line of the blast furnace, draw the outline sketch of the nut (matching the bolt specifications), and form an independent cast-in nut entity by rotation (without bolt holes for the time being), generating a total of 4 cast-in nut models; Protective sleeve: Based on the corresponding inlet and outlet water pipe positions, determine the plane where the protective sleeve is located, draw the outline sketch of the main body of the sleeve, determine the end face planes at both ends of the sketch and draw the end face outlines (matching the sleeve wall thickness requirements), draw the sleeve entity with the cavity retained by the lofting tool, and form 8 independent protective sleeve models. Lifting lug: Determine the plane where the lifting lug is located (avoiding the location of the cooling water pipe and protective sleeve), draw the outline sketch of the lifting lug (including the lifting hole structure), and form an independent lifting lug entity through a sweeping operation; The initial geometric models of the cooling wall body, cooling water pipes, water pipe bosses, bolt bosses, cast nuts, protective sleeves, and lifting lugs are integrated to ensure that the positions of each component meet the design constraints, thus forming the initial parameter model of the four-channel blast furnace cooling wall.

[0033] Then, the initial parameter model is optimized. First, the cooling wall body, water pipe boss, and bolt boss in the initial parameter model are merged to form an integrated cooling wall body foundation. Then, based on the merged cooling wall body, the difference is calculated with the cooling water pipe, cast nut, protective sleeve, and lifting lug (retaining the tool body) to obtain a cooling wall body entity with cavities (water pipe channel, nut mounting hole, sleeve hole, and lifting lug mounting groove). According to the design requirements, the cooling wall body is cut with dovetail grooves (matching the size of the inlay bricks, such as a groove type with a large end of 80mm and a small end of 65mm). The edges of the cooling wall body, the corners of the dovetail groove, and the edges of the lifting lugs are rounded (the radius of the rounded corners is 10mm or 5mm, depending on the structural strength requirements). The cooling water pipes and protective sleeves are subjected to shell removal (the shell removal thickness matches the design value of the water pipe wall thickness of 6.5mm and the sleeve wall thickness). Drill holes in the cast-in nuts (to match the bolt hole diameter) and thread them (e.g., M30×2 thread specification). Each optimized entity is generated into an independent component, and each component is assigned a corresponding material property. For example, the cooling wall body is made of gray cast iron (such as HT200), the cooling water pipe is made of seamless steel pipe, and the cast-in nut is made of carbon structural steel (such as Q235B).

[0034] Next, create an input form for the original design parameters and implement automatic model updates.

[0035] Specifically, an input form for original design parameters is created in Inventor software. Frequently modified parameters during the design process (e.g., cooling wall height, water pipe center distance, boss dimensions, dovetail groove depth, etc.) are categorized into basic parameters, water pipe parameters, and auxiliary structural parameters and listed in the form. The form interface supports direct input and modification of parameter values. When the designer adjusts parameter values ​​in the form, the software automatically updates the geometry and dimensions of the cooling wall 3D model based on preset parameter constraints and correlation algorithms, while simultaneously updating the relative positions of each component. This eliminates the need for manual adjustments to the model structure, ensuring the efficiency and accuracy of model modifications.

[0036] Import the optimized parameter model into the Workbench platform and add auxiliary models (such as furnace shell, filling layer, and refractory material layer) at the interface with the cooling wall. Set boundary conditions according to the actual operating conditions of the blast furnace, specifically including: Heat load conditions: Simulate the temperature distribution inside the blast furnace (e.g., the hot surface temperature of the refractory material in the belly region is 1200℃); Cooling conditions: Set the inlet temperature (e.g., 30℃), flow rate (e.g., 2.5m / s), outlet pressure of the cooling water in the cooling water pipe, and ensure that the furnace shell and air exchange heat through convection. Constraints: The displacement of the fixed cooling wall mounting surface is used to simulate the actual installation state; Thermal steady-state analysis calculations: The temperature field changes, thermal stress, and strain distribution of the cooling wall are calculated using the Workbench platform, specifically including: Temperature field analysis: Outputs the temperature gradient of key parts such as the cooling wall body, water pipes, and bosses, and identifies high-temperature areas (such as areas with temperatures exceeding 300°C). Stress-strain analysis: Calculate the equivalent thermal stress (e.g., whether it exceeds the material yield strength) and strain value of the cooling wall under thermal load, and locate stress concentration points (e.g., the connection between the bolt boss and the body). Generate an analysis report: clearly identify the location of high-temperature areas, the coordinates of stress concentration points, and their corresponding values, serving as the basis for parameter adjustments; Parameter Adjustment and Iterative Optimization: Based on the thermal steady-state analysis report, adjust the design parameters of the cooling wall, for example: If the temperature in a certain area is too high, reduce the spacing between the cooling water pipes in that area, increase the outer diameter of the water pipes, or optimize the water pipe layout. If stress concentration in a certain part exceeds the threshold, increase the radius of the fillet in that part, adjust the size of the boss, or optimize the material selection. Repeat the above steps after adjustment until the thermal steady-state analysis results meet the design requirements (such as the maximum temperature of the cooling wall being less than or equal to 350℃ and the maximum thermal stress being less than or equal to 80% of the material's yield strength), and obtain the target parameter model.

[0037] Finally, draw the engineering drawings and complete the design documents.

[0038] Creating an engineering drawing: Create a new engineering drawing in Inventor, select a drawing frame that conforms to national standards (such as A0 or A1 drawing frame), import the target parameter model, and determine the drawing scale (such as 1:20 or 1:50, to ensure the view is clear). Add engineering views: In addition to the basic views, add necessary auxiliary views, including front view, top view, left view (showing overall dimensions), sectional view (showing water pipe cavity and dovetail structure), and partial view (showing bolt boss and cast nut details). Dimensions and technical specifications: Dimensioning: Use the dimensioning tool to dimension the length (e.g., cooling wall height 1900mm), angle (e.g., wall rotation angle 9 degrees), diameter (e.g., water pipe outer diameter 73mm), radius (e.g., fillet radius 10mm), and roughness; Tolerance marking: Add tolerances (such as ±0.5mm, ±1mm) to critical dimensions (such as the center distance of water pipes 210mm, the distance of the boss from the top surface 380mm) to ensure machining accuracy; Add technical requirements to the blank areas of the drawings, including material acceptance standards, heat treatment requirements (such as normalizing treatment of the cooling wall body), and installation accuracy requirements (such as the gap between the cooling wall and the furnace shell ≤ 2mm). Bill of Materials Generation: Correct the model BOM (ensure the accuracy of component names, quantities, and material properties), insert the bill of materials into the engineering drawing, and indicate the specifications, materials, quantities, and remarks of each component (such as the carbon structural steel grade of the cooling water pipe). Design file saving: Save engineering drawings (formats such as .dwg, .idw) and target parameter models (formats such as .ipt, .iam) to form a complete design file package, facilitating subsequent production, processing, and design reuse. To further illustrate the technical solution of this invention, the following detailed explanation is provided with reference to specific implementation examples: Implementation Case: Design of a Four-Channel Cooling Wall for a 2500m³ Blast Furnace Initial parameters determined Based on the furnace parameters of the 2500m³ blast furnace (upper shell inflection point height 29850mm, inflection point radius 5750mm, lower shell inflection point height 24060mm, inflection point radius 6620mm, and the distance from the bottom of the cooling wall to the lower shell inflection point is 15mm), the original design parameters are determined as follows: Cooling wall basic parameters: number of blocks 50, height 1900mm, wall cross section thickness 235mm, wall side offset distance k1=15mm, k2=15mm, distance between cooling wall cold surface busbar and furnace shell busbar 30mm; Cooling water pipe parameters: 4 channels, outer diameter 73mm, wall thickness 6.5mm, vertical positioning of inlet / outlet pipes -100mm, center distance of inlet pipes 210mm, center distance of outlet pipes 200mm, distance of cooling water pipe centerline from the cold surface of the cooling wall 80mm; Auxiliary structural parameters: Water pipe boss thickness 25mm, major diameter 160mm; bolt boss minor diameter 160mm, distance from top / bottom surface 380mm; dovetail groove major end 80mm, minor end 65mm, depth 75mm, spacing 159mm, quantity 12.

[0039] Initial model construction Create a new part module in Inventor, import the above parameters, and construct related new parameters (such as the center point coordinates of the water pipe boss = the center coordinates of the cooling water pipe + the boss height compensation value). Use the stretch, rotate, sweep, and loft tools to create the cooling wall body (rotation angle 9°), 4 cooling water pipes (with cavity retained), 8 water pipe bosses (no cutting required after edge check), 4 bolt bosses (taper 1:10), 4 cast-in nuts, 8 protective sleeves, and 2 lifting lugs, and integrate them to form the initial parameter model.

[0040] Model optimization and form creation Perform Boolean operations on the initial model (union of the body and the boss, difference from other parts), cut dovetail grooves and round the corners (10mm edge rounding, 5mm dovetail groove rounding), shell the water pipes and sleeves (6.5mm thickness), drill holes for the nuts and machine M30×2 threads; create a parameter input form, add the cooling wall height, water pipe center distance, and boss size to the form, test parameter modifications (such as adjusting the cooling wall height to 2000mm), and the model automatically updates without errors.

[0041] Thermal steady-state analysis and parameter adjustment Import the model into Workbench, and add auxiliary models (such as furnace shell, filling layer, and refractory material layer). Set the furnace shell to convective heat exchange with air, the hot surface temperature of the refractory material to 1200℃, the cooling water inlet temperature to 30℃, and the flow rate to 2.5m / s. The calculated temperature of the cooling wall near the furnace belly reaches 400℃ (exceeding the design threshold), and the stress is concentrated at the root of the bolt boss (stress value 320MPa, the material undergoes plastic deformation). Adjust the parameters: reduce the spacing of the cooling water pipes in this area from 210mm to 190mm, change the vertical positioning of the inlet / outlet water pipes to -90mm, and increase the fillet radius of the bolt boss root from 5mm to 8mm. Reanalyze, and the temperature drops to 350℃, and the stress drops to 280MPa, meeting the design requirements.

[0042] Engineering drawing Select the A0 drawing frame, draw at a scale of 1:20, add a basic view, a sectional view (showing the water pipe cavity), and a partial view (showing the nut thread), add dimensions (including tolerances) and roughness, add technical requirements (such as HT200 material must comply with GB / T8163-2018), generate a parts list (including information on 1 cooling wall body, 4 cooling water pipes, and other components), and save the design file.

[0043] The design of the 2500m³ blast furnace cooling wall using this method shortened the design cycle from 15 days to 5 days using the traditional method, significantly improving the efficiency of parameter modification; the engineering drawings and the model were completely synchronized with no dimensional deviations; after optimization through thermal steady-state analysis, the actual operating maximum temperature of the cooling wall was 325℃, and the stress value was 275MPa, meeting the long-term operation requirements of the blast furnace, and no furnace body damage problems caused by insufficient cooling occurred.

[0044] In summary, the parametric design method for a four-channel blast furnace cooling wall provided in this specification determines the original design parameters based on the blast furnace volume and structural design requirements. These original design parameters include the number of cooling wall blocks, the outer diameter of the water pipes, the wall thickness, and the spacing. A new parts module is then created, importing the original design parameters and constructing associated new parameters using these parameters as independent variables. Based on the constraint relationship between the original and new parameters, initial geometric models of the cooling wall body, cooling water pipes, water pipe bosses, bolt bosses, cast nuts, protective sleeves, and lifting lugs are created using tools such as stretching, rotating, sweeping, and lofting, forming the initial parameter model of the four-channel blast furnace cooling wall. The initial parameter model is processed by performing a union operation on the cooling wall body, water pipe boss, and bolt boss. Then, based on the merged cooling wall body, the difference operation is performed on the cooling water pipe, cast-in nut, protective sleeve, and lifting lug. According to design requirements, the cooling wall body is cut with dovetail grooves and rounded corners. The cooling water pipe and protective sleeve are shelled, and the cast-in nut is drilled and threaded to obtain an optimized parameter model. An original design parameter input form is created, classifying and listing the target high-frequency modification parameters such as cooling wall dimensions and cooling water pipe layout parameters. Modifying parameter values ​​through the form triggers automatic model updates. The optimized parameter model is imported into the Workbench platform to simulate the blast furnace heat load distribution, temperature field changes, and stress-strain, conducting thermal steady-state analysis and generating performance evaluation results. Based on the performance evaluation results, the cooling water pipe layout and pipe diameter parameters are adjusted until a target parameter model that meets design requirements is obtained. In this way, it can be applied to the personalized design of blast furnace cooling walls with different volumes and furnace structures. It can automatically update the model and engineering drawings through parameter-driven operation, improve design efficiency and accuracy, and ensure the stable performance of the cooling wall under the high temperature conditions of the blast furnace.
