Description

Technical Field

[0001] This invention relates to the field of metallurgical cold rolling mill design, and more particularly to a method, apparatus and storage medium for creating a three-dimensional model of a cold rolling mill. Background Technology

[0002] The cold rolling mill process in the metallurgical industry is complex, involving a wide variety of equipment, numerous disciplines, and significant overlap, resulting in a complex system. Traditional two-dimensional design methods struggle to represent the spatial relationships between equipment and systems, hinder comprehensive and detailed inspections, and lead to low design efficiency, while also causing considerable challenges for subsequent construction. While the widespread application of three-dimensional design methods has alleviated these problems to some extent, they often lack effective organization, fail to extract the typical characteristics of the cold rolling mill, and rely on simple overlays and cross-referencing between different disciplines, equipment, and systems, lacking effective correlations. Equipment positioning relies on mutual references, and changes in equipment or quantity can trigger global model updates or errors, making design updates and iterations difficult and hindering the standardization of mill design. Summary of the Invention

[0003] To address the aforementioned problems in the prior art, this invention provides a method, apparatus, and storage medium for establishing a three-dimensional model of a cold rolling mill, thereby enabling the design of a parameterized three-dimensional model of a cold rolling mill that is easy to standardize and update.

[0004] To achieve the above objectives, a method for establishing a three-dimensional model of a cold rolling mill is provided, including:

[0005] S1. Establish the three-dimensional coordinate system of the unit based on the factory coordinate system and the layout and positioning of the cold rolling mill.

[0006] S2, using the three-dimensional coordinate system of the unit as a reference, establish a three-dimensional single-line diagram of the cold rolling mill based on the strip direction in the cold rolling mill process flow. The three-dimensional single-line diagram of the unit includes:

[0007] Strip passing line, used to mark the line segment of the strip direction in the process flow;

[0008] The strip is set on the strip passing line to mark the starting point, turning point and ending point of the strip process changes in the process flow;

[0009] Location markers are used to indicate the positions of the process equipment of the cold rolling mill and the auxiliary equipment of the auxiliary system of the cold rolling mill in the process flow.

[0010] S3. Based on the configuration of the cold rolling mill process equipment and the individual three-dimensional model of the process equipment, establish a first mapping relationship between the individual three-dimensional model of the process equipment and the position of the process equipment in the three-dimensional single-line diagram of the mill, and obtain a three-dimensional layout diagram of the process equipment based on the first mapping relationship and the three-dimensional single-line diagram of the mill.

[0011] S4. Based on the configuration of the auxiliary system of the cold rolling mill and the three-dimensional model of the auxiliary system, establish a second mapping relationship between the three-dimensional model of the auxiliary system and the location of the auxiliary equipment in the three-dimensional single-line diagram of the mill, and obtain a three-dimensional layout diagram of the auxiliary system based on the second mapping relationship and the three-dimensional single-line diagram of the mill.

[0012] S5. Based on the three-dimensional layout diagram of the process equipment and the three-dimensional layout diagram of the auxiliary system, establish the connection between the process equipment and the auxiliary system;

[0013] S6. Based on the three-dimensional layout diagram of the process equipment, the three-dimensional layout diagram of the auxiliary system, and the connection, a three-dimensional layout diagram of the factory facilities is established. The three-dimensional layout diagram of the process equipment, the three-dimensional layout diagram of the auxiliary system, the connection, and the three-dimensional layout diagram of the factory facilities are merged to obtain a three-dimensional model diagram of the cold rolling mill.

[0014] Furthermore, the three-dimensional single-line diagram of the unit, the three-dimensional layout diagram of the process equipment, the three-dimensional layout diagram of the auxiliary system, and the three-dimensional layout diagram of the plant facilities are each designed in a distributed manner, and in the distributed design, the three-dimensional single-line diagram of the unit, the three-dimensional layout diagram of the process equipment, the three-dimensional layout diagram of the auxiliary system, and the three-dimensional layout diagram of the plant facilities share the same coordinate origin in the three-dimensional coordinate system of the unit.

[0015] Furthermore, the unit's three-dimensional coordinate system includes the unit's coordinate origin, three-dimensional coordinate axes, column axes, and elevation lines.

[0016] Furthermore, establishing the unit's three-dimensional coordinate system includes:

[0017] Set the position with predetermined characteristics on the centerline of the unit as the origin of the unit's three-dimensional coordinate system;

[0018] The directions of the three coordinate axes are set as follows: pointing towards the unit's operating side or drive side; inlet / outlet; perpendicular to the ground.

[0019] Set the center line of the factory building's columns as the column axis;

[0020] Elevation lines are set according to locations with regional layout characteristics.

[0021] Furthermore, the locations with regional layout characteristics include the unit's zero-plane, basement, or above-ground platform.

[0022] Furthermore, the positions and dimensions of points and lines in the unit's three-dimensional single-line diagram are represented parametrically using parameters; the unit's three-dimensional single-line diagram changes as the parameters change.

[0023] Furthermore, the first mapping relationship and the second mapping relationship are established by labeling the process equipment and the auxiliary equipment with their numbers.

[0024] On the other hand, an apparatus is provided for a method of establishing a three-dimensional model of a cold rolling mill, including a memory and a processor, the memory storing at least one program, the at least one program being executed by the processor to implement the method of establishing a three-dimensional model of a cold rolling mill as described above.

[0025] In another aspect, a computer-readable storage medium is provided, the storage medium storing a computer program that, when executed by a processor, implements the steps of the method described above.

[0026] The above technical solution has the following technical effects:

[0027] The method for establishing a three-dimensional model of a cold rolling mill in this embodiment of the invention uses the cold rolling mill process flow as a reference. Based on the route of the strip passing through the mill, forming the strip passage line, a three-dimensional single-line diagram of the mill is first established. The positions of process equipment and auxiliary equipment in the auxiliary system are marked on this diagram using parameterized strip passage lines as references. Then, based on this diagram, three-dimensional layout diagrams of the process equipment, auxiliary systems, and plant facilities are established. Finally, a three-dimensional model of the cold rolling mill is created. This embodiment of the invention, through parameterized association on the three-dimensional single-line diagram, modularizes complex mills, facilitating design, implementation, and modification.

[0028] The technical solution of this invention, combined with the characteristics of a cold-rolled strip steel production line, divides the unit into several units, linking each design model with the production process flow as the hub. Each piece of equipment is based on the process flow, and only when the process flow changes will the model be updated globally. Modifications to the design or quantity of the equipment itself will not affect other equipment in the process flow, which is particularly important in large-scale and complex 3D design work. The technical solution of this invention overcomes the shortcomings of traditional 3D design methods where equipment positioning relies on mutual reference, and when equipment design modifications or changes in quantity occur, the model is updated globally or errors occur. This improves the efficiency and accuracy of 3D design for the unit, and facilitates the parameterization, productization, and serialization of cold rolling mill design. Attached Figure Description

[0038] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention, primarily used to illustrate the embodiments and to explain the operating principles of the embodiments in conjunction with the relevant descriptions in the specification. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0039] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0040] Example 1:

[0041] Figure 1 This is a flowchart illustrating the method for establishing a three-dimensional model of a cold rolling mill in this embodiment. Figure 1 The method in this embodiment includes:

[0042] S1. Establish the three-dimensional coordinate system of the unit based on the factory coordinate system and the layout and positioning of the cold rolling mill.

[0043] The unit's three-dimensional coordinate system includes an origin, three-dimensional coordinate axes, column axes, and elevation lines. The origin can be set at a predetermined location, such as the unwinding start point, the unit's center point, or the winding end point on the unit's centerline. The three coordinate axes can be oriented as follows: pointing towards the unit's operating side or transmission side, inlet / outlet, and perpendicular to the ground. The unit's three-dimensional coordinate system also includes column axes and elevation lines. The centerline of the plant's columns can be set as the column axes, and elevation lines can be set at locations or areas with regional layout characteristics, such as the unit's zero plane, basement, or above-ground platform.

[0044] Figure 3 This diagram illustrates the XY plane grid of the three-dimensional coordinate system of the unit according to an embodiment of the present invention. In this grid diagram, the numerically labeled column axes are the centerlines of the plant's columns, and the unit's centerline serves as the central straight line. Figure 3 One can take a point on the center line of the unit as the origin of the coordinate system. Figure 3 The diagram shows the origin of a coordinate system defined by the axis of column 9 and the centerline of the unit, but in practice, it is not limited to using this coordinate system. Figure 3 The coordinate system origin can be determined by using other column axes along with the unit centerline, in addition to the axis of column 9. Figure 3 In this diagram, the Y-axis points from the unit's centerline towards the unit's inlet side, the X-axis is perpendicular to the Y-axis and points towards the unit's operating side, and the Z-axis is perpendicular to the XY plane where this grid diagram is located. The selection of the X and Y axes can be based on actual needs. For example, the unit's three-dimensional coordinate system in this embodiment of the invention can be implemented using AutoCAD, which specifies a unified coordinate origin and grid diagram. The unit's three-dimensional single-line diagram is a three-dimensional sketch of the strip passing through the steel line, established using the unit's three-dimensional coordinate system as the design benchmark, completely displaying the strip's trajectory in the cold rolling process.

[0045] For example, the unit's three-dimensional coordinate system can be obtained by transforming the existing factory coordinate system.

[0046] S2, using the unit's three-dimensional coordinate system as a reference, establishes a three-dimensional single-line diagram of the cold rolling mill based on the strip's orientation in the cold rolling mill's process flow. The unit's three-dimensional single-line diagram includes:

[0047] The strip passage line is used to mark the line segment indicating the direction of the strip in the process flow. The strip passage line is marked with starting points, turning points, and ending points indicating the changes in the strip process. Positioning marks are used to mark the positions of process equipment and auxiliary equipment of the cold rolling mill in the process flow. All starting points, turning points, ending points, and positioning marks of the cold rolling mill strip included in the above-mentioned three-dimensional single-line diagram of the strip are parametrically positioned. The positions and dimensions of points and lines in the three-dimensional single-line diagram of the mill are parametrically represented using parameters, and the three-dimensional single-line diagram of the mill changes as the parameters change.

[0048] like Figure 2 The diagram shown is a partial schematic of the process flow of a cold rolling mill according to an embodiment of the present invention. The process flow includes: uncoiling, thickness measurement, shearing, welding, inlet looper, alkaline spray washing, alkaline brush washing, electrolytic cleaning, water brush washing, water spray washing, drying device, annealing furnace, coiler, etc. The process flow can be varied according to different actual conditions.

[0049] Figure 4 This is a schematic elevation view of a three-dimensional single-line diagram of the rolling mill established in an embodiment of the present invention. Only a portion of the process flow is shown as an example of the three-dimensional single-line diagram of the rolling mill. The three-dimensional single-line diagram of the rolling mill can be established for a simplified cold rolling process. The specific simplification can be based on actual needs. Figure 4 As shown in the figure, line segment 401 represents a portion of the strip's path in the entire cold rolling process, forming the strip passing line. Due to space limitations, Figure 4 Only a portion of the strip passing through the steel line is shown. Besides the strip passing through the steel line, Figure 4 The document also shows the starting and turning points of strip steel process changes, such as 403, as well as positioning lines indicating the locations of equipment such as process equipment or auxiliary equipment. Because... Figure 4 It's only a part of the complete 3D single-line diagram of the unit, so Figure 4 The endpoint was not shown. Figure 4 In the diagram, equipment positioning lines are represented by dashed lines, such as position 402 for the welding machine. The unit's 3D single-line diagram also uses positioning marks to indicate the positions of corresponding process equipment and auxiliary equipment in auxiliary systems. The unit's 3D single-line diagram can selectively indicate the positions of representative process equipment and auxiliary equipment as needed. In one implementation of the unit's 3D single-line diagram, equipment positions are indicated by displaying positioning lines on the 3D single-line diagram, while the positions and dimensions of each process equipment and auxiliary equipment are parametrically marked in the background, corresponding to the aforementioned positioning lines. Figure 4The text in the diagram is merely an illustrative description of some of the process equipment at the corresponding location and does not imply that these textual descriptions are present on the unit's 3D single-line diagram. Figure 4 The locations of the following process equipment are illustrated in text: uncoiler 1 (starting point), uncoiler 2, thickness gauge, inlet shear, welding machine, inlet looper, alkaline spray washing tank, alkaline washing brush tank, electrolytic cleaning tank, water brush washing tank, water spray washing tank, drying device, annealing furnace, etc. Other positioning lines without textual descriptions do not indicate the absence of process equipment at those locations; the corresponding positioning lines indicate the relevant process equipment and its location through parameterization in the background. Of course, in addition to these process equipment, the cold rolling process also includes straightening equipment, shearing equipment, scrap handling equipment, welding machine, pickling tank, drying equipment, industrial furnace, coating equipment, tensioning devices, steering devices, web guiding devices, conveying devices, coiling equipment, and other equipment that processes strip steel and is located in the strip steel production or transportation channels. Based on the simplified process, the locations of these devices can be selectively marked on the unit's 3D single-line diagram. Besides equipment positioning lines, other methods such as nodes can also be used to mark the locations of corresponding equipment. Regardless of the location marking method, the common feature is that it parametrically marks the name, number, location and / or size of the auxiliary equipment of the process equipment and / or auxiliary system.

[0050] For example, the 3D sketching module of software such as Inventor or SolidWorks can be used to define positional and dimensional parameters and create a 3D single-line diagram of the unit. S3, based on the configuration of the cold rolling mill's process equipment and the individual 3D models of the process equipment, a first mapping relationship is established between the individual 3D models of the process equipment and the positions of the process equipment in the unit's 3D single-line diagram. A 3D layout diagram of the process equipment is obtained based on the first mapping relationship and the unit's 3D single-line diagram. There is an assembly dimension relationship between each individual 3D diagram and the process equipment indicated in the unit's 3D single-line diagram. When individual equipment is modified, the 3D single-line diagram is modified, or the assembly relationship is modified, the 3D layout diagram of the process equipment can be modified accordingly. Figure 5 This is an elevation view of a three-dimensional layout of process equipment established in an embodiment of the present invention.

[0051] In practice, the individual 3D model of the process equipment can be a pre-built model that already exists in the equipment library, or it can be a newly designed model drawing.

[0052] As described above, the process equipment may include: uncoiling equipment, straightening equipment, shearing equipment, waste processing equipment, welding machines, loopers, cleaning tanks, pickling tanks, drying equipment, industrial furnaces, coating equipment, tensioning devices, steering devices, web guiding devices, conveying devices, coiling equipment, and other equipment used to process strip steel, located in the strip steel production or transportation channels. For example, this embodiment can use the assembly function of software such as Inventor to create a three-dimensional layout diagram of the unit's process equipment.

[0053] S4. Based on the configuration of the auxiliary system of the cold rolling mill and the three-dimensional model of the auxiliary system, establish a second mapping relationship between the three-dimensional model of the auxiliary system and the position of the auxiliary equipment in the three-dimensional single-line diagram of the mill, and obtain a three-dimensional layout diagram of the auxiliary system based on the second mapping relationship and the three-dimensional single-line diagram of the mill; for example, the numbers of the process equipment and the auxiliary equipment are marked to establish the first mapping relationship and the second mapping relationship.

[0054] In practical implementation, the auxiliary system can be presented as a concrete model or a black-box integrated model. The 3D model of the auxiliary system can be a pre-built model existing in the equipment library or a newly designed model drawing. Based on the configuration of the auxiliary system of the cold rolling mill, a second mapping relationship is established between the 3D model of the auxiliary system and the corresponding equipment on the 3D single-line diagram, and assembly and connection are performed to obtain the 3D layout drawing of the auxiliary system. There is an assembly dimension relationship between the 3D model drawing of each auxiliary system and the corresponding equipment on the 3D single-line diagram of the mill. When the auxiliary system is modified, the 3D single-line diagram is modified, or the mapping relationship is modified, the 3D layout drawing of the process equipment is modified accordingly.

[0055] For example, Figure 6 This is a schematic diagram of the three-dimensional layout of the auxiliary system established in an embodiment of the present invention; wherein, only a portion of the auxiliary system layout in the process flow is shown as an example. Figure 6 The auxiliary systems may include dust removal equipment, exhaust gas purification equipment, circulating media systems, hydraulic systems, compressed air systems, lubrication systems, electrical systems, and other equipment located outside the unit production line that provide energy input and waste treatment output for online equipment. For example, software such as Inventor, Plant3D, and Revit can be used on the unified design platform Vault, referring to the 3D layout drawing of the process equipment, to design and obtain the 3D layout drawing of the auxiliary systems.

[0056] S5. Based on the 3D layout diagram of the process equipment and the 3D layout diagram of the auxiliary system, establish the connection between the process equipment and the auxiliary system; this connection is updated according to design modifications of the group 3D single-line diagram, the 3D layout diagram of the process equipment, and the 3D layout diagram of the auxiliary system. For example, the connection includes piping connections. In specific implementations, the connection between the process equipment and the auxiliary equipment includes various media pipes, cables, cable trays, and various attached connectors, detection elements, control elements, pipe insulation layers, pipe supports, etc.

[0057] For example, Figure 7 This is a schematic diagram of a three-dimensional layout of pipe connections established in a method according to an embodiment of the present invention. The diagram also includes auxiliary systems connected to the pipes. Only a portion of the connecting pipes in the process flow are shown as an example. Exemplarily, software such as Inventor, Plant3D, and Revit can be used on the unified design platform Vault, referring to the three-dimensional layout of the process equipment, to design and obtain the three-dimensional layout of the auxiliary system.

[0058] S6. Based on the three-dimensional layout drawings of process equipment, auxiliary systems, and connections, establish a three-dimensional layout drawing of the plant facilities; merge the three-dimensional layout drawings of process equipment, auxiliary systems, connections, and plant facilities to obtain a three-dimensional model drawing of the cold rolling mill.

[0059] Figure 8 This is a schematic diagram of a three-dimensional layout of a factory facility established according to an embodiment of the present invention. In a specific implementation, the three-dimensional layout of the factory facility can be an existing three-dimensional drawing. After converting the coordinate system of the existing three-dimensional drawing to the coordinate system of the unit, it is merged with the obtained three-dimensional layout of the process equipment, the three-dimensional layout of the auxiliary system, and the connection to obtain a three-dimensional model of the cold rolling mill. Figure 9 This is a schematic diagram of a three-dimensional model of a cold rolling mill established in an embodiment of the present invention. Figure 9 As can be seen, in this example, the cold rolling mill is arranged in the entire three-dimensional space, and the route or path that the strip steel travels may not actually be on a plane, but rather three-dimensional. Figure 3 The lines shown in the diagram represent only one elevation view of the three-dimensional single-line diagram.

[0060] For example, software such as Revit can be used on a unified design platform like Vault to design the building, steel structure, and civil engineering foundation (including embedded plates, embedded pipes, and bolts) based on existing design models, resulting in a 3D model of the factory facilities. Then, software such as Navisworks can be used to integrate the 3D layout drawings of process equipment, auxiliary systems, and connections with the 3D model of the factory facilities, yielding a result such as... Figure 9 The diagram shows a three-dimensional model of the cold rolling mill.

[0061] Using the method of this invention, the three-dimensional single-line diagram of the unit, the three-dimensional layout diagram of the process equipment, the three-dimensional layout diagram of the auxiliary system, and the three-dimensional layout diagram of the plant facilities are each designed in a distributed manner, and in the distributed design, the three-dimensional single-line diagram of the unit, the three-dimensional layout diagram of the process equipment, the three-dimensional layout diagram of the auxiliary system, and the three-dimensional layout diagram of the plant facilities share the same coordinate origin in the three-dimensional coordinate system of the unit.

[0062] In the technical solution of this invention, a three-dimensional single-line diagram of the unit is first constructed based on the strip passage route of the surface strip in the cold rolling process. The entire three-dimensional model of the unit is then built based on this single-line diagram. The positions and dimensions of points and lines in the unit's three-dimensional single-line diagram are all parametrically represented using parameters; the three-dimensional single-line diagram changes with the parameters. That is, when designing or establishing a three-dimensional model of a cold rolling mill using the solution of this invention, parametric design is achieved, overcoming the shortcomings of existing technologies in achieving standardization, and improving the efficiency and accuracy of the unit's three-dimensional design.
