Description

Technical Field

[0001] This invention relates to the field of rolling mill piping, and more particularly to a method for designing and covering piping in cold rolling mills. Background Technology

[0002] Cold rolling mills, as crucial equipment in the steel industry for the plastic processing of metals, involve a variety of energy media. These different energy media must be correctly connected to the equipment via pipelines to ensure normal and stable operation. However, due to the numerous types and complex structures of these energy media pipelines, the entire process, from initial pipeline design to on-site installation and commissioning, is fraught with challenges such as a large workload, tedious procedures, and the risk of installation errors. This significantly hinders production efficiency and increases costs.

[0003] Specifically, since most existing piping systems are designed based on the experience of staff, this greatly increases the limitations of the piping structure. This often results in situations such as missing piping, chaotic layout, and difficult connections, which have a significant impact on on-site pipeline construction and subsequent maintenance.

[0004] Currently, there is no effective solution to the problem that the large number of pipes in cold rolling mills leads to a large workload, complicated process, and easy assembly errors in the relevant technologies.

[0005] Therefore, this invention proposes a piping design and installation method for cold rolling mills to overcome the shortcomings of existing technologies. Summary of the Invention

[0006] The purpose of this invention is to provide a method for designing and covering piping in cold rolling mills, which can be carried out efficiently from the initial design to on-site construction according to the preset method, thereby improving construction efficiency; in addition, since each work link is traceable, clear and efficient traceability can be achieved.

Step S5: Install piping on the cold rolling mill according to the three-dimensional model of the piping structure of the cold rolling mill.

[0009] In a preferred embodiment of the present invention, in step S3, the parameter list includes: equipment drawing number, equipment name, number of pipelines corresponding to each energy medium, flow rate of each energy medium, pressure of each energy medium in the corresponding pipeline, and structural form of each pipeline.

[0010] In a preferred embodiment of the present invention, a three-dimensional pipe fitting database is established in advance before step S3; The three-dimensional pipe fittings database contains a variety of standard structural components required to establish a three-dimensional model of the piping structure of the cold rolling mill.

[0011] In a preferred embodiment of the present invention, in step S4, in the established three-dimensional model of the cold rolling mill piping structure, the structural component with the moving function is positioned at the extreme position on its travel path.

[0012] In a preferred embodiment of the present invention, step S5 includes: Step S501: Install the pipe support at the preset position on the cold rolling mill; Step S502: Set a mounting plate, and configure the pipe diameter on the mounting plate as needed, and open mounting holes on the mounting plate; Step S503: Insert each pipe into the corresponding mounting hole and secure each pipe with clamps; Step S504: Divide the cold rolling mill into multiple regions according to the different energy media in each of the pipelines; Step S505: Install piping in each of the multiple areas on the cold rolling mill.

[0013] In a preferred embodiment of the present invention, each of the pipelines and the corresponding valves are connected according to the fluid system schematic diagram of the energy medium.

[0014] In a preferred embodiment of the present invention, a splash guard is provided at the interface of the pipeline and on the side near the cold rolling mill, and the splash guard has a through hole for the pipeline to pass through.

[0015] In a preferred embodiment of the present invention, a sealing baffle is provided on the splash guard. The sealing baffle is formed by splicing together at least two plate parts. The sealing baffle is arranged around the outer periphery of the pipe passing through the splash guard to seal the gap between the pipe and the inner wall of the through hole.

[0016] In a preferred embodiment of the present invention, the piping design and installation method for cold rolling mills further includes: Step S6: Based on the installation positions of each of the pipes on the cold rolling mill, form an installation position diagram for each of the pipes; Multiple sets of diagrams are formed according to the type of energy medium, and the pipelines in each set of diagrams correspond to the same energy medium.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] like Figure 1As shown, the present invention provides a method for designing and covering piping in a cold rolling mill, which includes the following steps: Step S1: Obtain parameter data for the cold rolling mill piping according to preset conditions; wherein, the parameter data for the cold rolling mill piping includes the type and quantity of energy medium required for the cold rolling mill piping; Step S2: Based on the parameter data of the cold rolling mill piping, form the corresponding fluid system schematic diagram of the energy medium; In this process, corresponding valves are configured on each pipeline in the fluid system schematic. Different types of energy media require the design of corresponding valves, such as valves for low-pressure hydraulic systems, high-pressure hydraulic systems, emulsion systems, and air systems.

[0025] Step S3: Based on the parameter data of the cold rolling mill piping and the schematic diagram of the fluid system of the energy medium, form a parameter list; Step S4: Based on the data in the parameter list, establish a three-dimensional model of the piping structure of the cold rolling mill; in the three-dimensional model, mark the interface positions and dimensions of each pipe. Step S5: Based on the three-dimensional model of the piping structure of the cold rolling mill, install the piping on the cold rolling mill; wherein, each pipeline and corresponding valve can be connected according to the fluid system schematic diagram of the energy medium.

[0026] This application provides a detailed process for the design and installation of piping for cold rolling mills. Through standardized procedures and the guidance of a 3D model, it avoids problems such as pipe omissions, chaotic layouts, and connection difficulties that often arise from traditional experience-based designs. This significantly reduces on-site installation workload and assembly error rates. The piping design and installation method for cold rolling mills presented in this application can be efficiently implemented from initial design to on-site construction, effectively improving construction efficiency.

[0027] This application, by marking the interface locations and dimensions in the 3D model (step S4) and generating drawings according to the type of energy medium, ensures that each step is traceable, allowing on-site construction personnel to clearly understand the pipeline connection methods, and making subsequent maintenance traceability clear and efficient. In addition, by using the 3D model and fluid system schematic diagram, collision and interference problems between pipelines and between pipelines and equipment can be avoided in advance. Pipelines can be prefabricated and pre-installed on the manufacturing site based on the model, thereby enabling the early detection and resolution of assembly problems and reducing the need for on-site pipeline modifications.

[0028] In an optional embodiment of the present invention, in step S1 above, the parameter data for the cold rolling mill piping further includes: control requirements for each pipeline in the cold rolling mill piping. Specifically, in the actual design process, based on engineering needs and user requirements, staff (such as cold rolling mill designers) can summarize and organize the types, quantities, and control requirements (such as pressure fluctuation range, temperature control accuracy, flow regulation response time, valve opening and closing sequence, etc.) of the energy medium required for the cold rolling mill piping.

[0029] Furthermore, in step S1 above, problem warning records can be made. Since there may be situations where the overall consideration is not comprehensive or the user adds control requirements later, during the process of obtaining the parameter data of the cold rolling mill piping, the staff can make corresponding warning records for the problems found and the user's subsequent control requirements, so as to eliminate the corresponding warning problems before leaving the factory and avoid the possible impact during on-site construction.

[0030] In an optional embodiment of the present invention, a three-dimensional pipe fitting database is pre-established before step S3. This database contains various standard structural components required for creating a three-dimensional model of the piping structure of a cold rolling mill. By pre-setting various standard structural components (such as connector types and hose models) that may be used in the three-dimensional pipe fitting database, the corresponding structural components can be directly called during the three-dimensional model creation process, thereby improving the efficiency of three-dimensional design.

[0031] In an optional embodiment of the present invention, in step S3 above, the parameter list may include, but is not limited to: equipment drawing number, equipment name, number of pipelines corresponding to each energy medium, flow rate of each energy medium, pressure of each energy medium in the corresponding pipeline, and structural form of each pipeline. Specifically, the "equipment name" indicates the endpoint to which the energy medium needs to be supplied; the "number of pipelines corresponding to each energy medium" displays the number of equipment requiring the energy medium; the "flow rate of each energy medium," "cylinder diameter / rod diameter," and other parameters display the corresponding parameters of the equipment requiring the energy medium; the "pressure of each energy medium in the corresponding pipeline" displays the pressure of the energy medium in the corresponding pipeline; the "equipment drawing number in the cold rolling mill" (such as "intermediate pipeline diameter" and "basic pipeline number") displays the fluid system schematic diagram of the energy medium in step S2 above, along with the interface dimensions and numbers of each pipeline; and the "structural form of each pipeline" displays the type (such as threaded connection, flange connection, etc.) and interface dimensions of the energy medium equipment's interface. By configuring the parameter list, staff can select the corresponding equipment and pipelines based on the parameter list and the fluid system schematic diagram, thereby improving modeling efficiency. Furthermore, the order and / or location of energy medium interfaces and intermediate pipeline interfaces on each pipeline can be determined, ensuring that the interfaces are connected sequentially during subsequent connection processes. This not only simplifies the connection process and improves connection efficiency but also effectively avoids incorrect connections.

[0032] In an optional embodiment of the present invention, in step S4 above, in the established three-dimensional model of the cold rolling mill piping structure, the structural components with movable functions are positioned at their extreme positions along their travel paths. This design facilitates ensuring that the length of the pipeline (such as a flexible hose) can meet the normal connection requirements of the structural components within their range of motion during piping installation. Furthermore, when structural components with movable functions are present, their extreme travel range can be recorded to avoid laying pipelines within this range as much as possible, thereby preventing interference. Existing modeling methods can be used to create the three-dimensional model of the cold rolling mill piping structure; the specific steps for establishing the three-dimensional model are not limited here.

[0033] In this embodiment, due to the high complexity of the cold rolling mill's structure, a large amount of energy medium is required. Designing using two-dimensional drawings would be extremely cumbersome, time-consuming, and labor-intensive. Furthermore, the actual pipeline structure formed by connecting the two-dimensional drawings may have deviations in its routing, potentially leading to collisions and interference with other structures within the cold rolling mill. Therefore, this invention establishes a three-dimensional model of the cold rolling mill's piping structure to ensure accuracy in the actual pipeline connection process and avoid interference. Additionally, during the establishment of the three-dimensional model, some equipment (such as the mill guard, platform, front and rear guide plates, and front and rear pressure rollers) does not involve the transportation and supply of energy medium, but since these devices also occupy some piping space, they also need to be represented in the three-dimensional model.

[0034] In an optional embodiment of the present invention, such as Figure 2 As shown, step S5 above includes: Step S501: Install the pipe support 1 at the preset position on the cold rolling mill; Different pipe supports 1 can be installed according to the routing and zoning of the various pipelines on the cold rolling mill, thereby meeting different piping requirements. The pipe support 1 can be a detachable, integrated component for easy assembly and disassembly. Before leaving the factory, corresponding pipelines can be pre-assembled on the pipe support 1 for testing to ensure that there is no interference between pipeline routes. Furthermore, since each pipeline is assembled on the pipe support 1, the independent and detachable design of the pipe support 1 eliminates the need for pre-installation of pipelines after the cold rolling mill body is assembled, thus optimizing the process and saving time.

[0035] Step S502: As Figure 4 and Figure 5 As shown, a mounting plate 2 is pre-set, and the pipe diameter of the pipeline is configured on the mounting plate 2 as needed. Mounting holes 201 are opened on the mounting plate 2. Step S503: Insert each pipe into the corresponding mounting hole 201 and fix each pipe with clamps (not shown); Step S504: Divide the cold rolling mill into multiple zones according to the different energy media in each pipeline; Specifically, due to the large variety and quantity of energy media required for piping, if only one worker were to handle the piping for the entire system, the workload would be enormous, making it impossible to guarantee the rationality of the design timeline. Therefore, in this invention, the cold rolling mill can be pre-divided into multiple areas based on the characteristics of each energy media type. This allows one or more workers to handle the piping according to different areas, minimizing the possibility of mutual interference between the pipelines of different energy media. For example... Figure 3As shown, the emulsion pipeline 3 can be set at the bottom of the mill, and the hydraulic pipeline can be set at the drive side and the operating side at the top of the mill. Then, it can be connected to the high-pressure valve frame and the low-pressure valve frame located at the top of the platform through the intermediate pipeline (generally divided into high-pressure valve frame and low-pressure valve frame, one of the high-pressure valve frame and the low-pressure valve frame is set on the operating side and the other is set on the drive side. The high hydraulic pipeline 4 is connected to the high-pressure valve frame through the intermediate pipeline, while the low hydraulic pipeline 5 is connected to the low-pressure valve frame through the intermediate pipeline).

[0036] Furthermore, for the piping of the cold rolling mill, since there are fewer air lines 6, the air valve holder will be installed on the mill platform. The piping of air lines 6 and hydraulic lines can be designed together (or completed by the same worker). Because the thin oil lubrication line 7 has a larger diameter and lower system pressure, it can be designed together with the emulsion line 3 (or completed by the same worker). Through the above-described zoned piping design of the cold rolling mill based on the energy medium, piping efficiency can be maximized while minimizing interference between pipelines.

[0037] Step S505: Install piping in multiple areas of the cold rolling mill.

[0038] In one specific embodiment of the present invention, the pipe support 1 can be an emulsion pipe support. Since the emulsion pipeline has a large diameter but low system pressure, it can be clamped and fixed using clamps. When installing each pipeline, the corresponding mounting hole 201 and clamp can be selected according to the actual situation, thereby facilitating the adjustment of the pipeline assembly position and greatly increasing the flexibility of installation and adjustment.

[0039] In an optional embodiment of the present invention, a shared platform can be set up to design the three-dimensional model of the piping structure of the cold rolling mill. This allows different personnel to perform three-dimensional design on the same shared platform, with preset access permissions between them. This enables collaborative design of various pipelines, ensuring no interference occurs between pipelines carrying different energy media, thereby improving design efficiency. The piping design method of the present invention, based on a three-dimensional model of the same rolling mill assembly, divides the layout into zones according to the type of energy medium to improve design efficiency. Furthermore, a shared design platform or workstation can be established via a network, allowing for pipeline configuration for different types of energy media, or for different parts of the pipeline for the same energy medium. Through permission-based sharing, different personnel can query the pipeline routes designed by other personnel at any time, thereby optimizing their own pipeline routes and layouts, achieving collaborative design and effectively improving piping efficiency.

[0040] During the piping process, leaks may occur at pipe joints. Therefore, butt-welded joints are used as much as possible to prevent leaks; union joints are used only at pipe joints where disassembly is considered. Additionally, flexible hoses are used for connections at energy medium pipe interfaces. However, for some critical hydraulic medium interfaces (such as the inlet of bending cylinders), flexible hoses can also be used to prevent pipe deformation and leaks caused by vibrations from the cold rolling mill or installation. This provides a buffering effect, facilitating installation and disassembly while effectively protecting the pipes.

[0041] In an optional embodiment of the present invention, such as Figure 6 and Figure 7 As shown, a splash guard 8 is installed at the interface of the pipeline and near the side of the cold rolling mill. The splash guard 8 has a through hole 801 for the pipeline to pass through. The splash guard 8 can effectively prevent liquids (such as emulsions) from splashing.

[0042] Furthermore, such as Figure 6 As shown, a sealing baffle 9 is fixed to one side of the splash baffle 8 by multiple bolts. The sealing baffle 9 can be formed by splicing together at least two parts of the plate. The sealing baffle 9 is arranged around the outer periphery of the pipe passing through the splash baffle 8, so that the gap between the pipe and the inner wall of the through hole 801 can be sealed by the sealing baffle 9.

[0043] In an optional embodiment of the present invention, the piping design and installation method for cold rolling mills further includes: Step S6: Based on the installation positions of each pipeline on the cold rolling mill, create installation position diagrams for each pipeline. Multiple diagram sets are created according to the type of energy medium, with each set containing pipelines corresponding to the same energy medium. For example, hydraulic pipelines can have separate installation position diagrams, emulsion pipelines can have separate installation position diagrams, etc. Pipelines are numbered according to a pre-set parameter list in their respective installation position diagrams. This allows for pre-installation and inspection of each pipeline on the piping support 1 before shipment, effectively improving piping efficiency and reducing the possibility of piping errors. After pre-installation and inspection, each pipeline is disassembled, and each pipeline is labeled and numbered according to the drawing number or pipeline number on the drawings to ensure correctness and improve efficiency during on-site reassembly.

[0044] The features and advantages of the cold rolling mill piping design and laying method of the present invention are as follows: I. The piping design and laying method of this cold rolling mill, through the overall design of the cold rolling mill piping, not only clarifies the design steps of each pipeline, but also clarifies and accurately identifies the connection points between each pipeline, which facilitates prefabrication and pre-installation before leaving the factory, greatly reduces the possibility of interference after the pipeline is installed, effectively saves design time, and improves the efficiency and reliability of pipeline design.

[0045] Second, the piping design and laying method of this cold rolling mill has a verifiable record of the location and connection relationship of each pipeline interface (such as the energy medium interface and the intermediate pipeline interface), which facilitates traceability in subsequent assembly and maintenance processes; piping can be carried out based on the fluid system schematic diagram, parameter list and pre-established three-dimensional model, which facilitates the simultaneous development of multiple aspects (such as the production of on-machine pipelines, valve station production, etc.) and improves the efficiency of pipeline design.

[0046] Third, the piping design and laying method of this cold rolling mill can prefabricate each pipeline according to the pre-edited number or drawing number and pre-install each pipeline on the piping support 1, which can effectively improve efficiency and reduce the possible failures of on-site pipeline modification.

[0047] IV. The piping design and laying method of this cold rolling mill uses a pre-established three-dimensional model as the basis for piping, which can effectively avoid possible interference between pipelines and between pipelines and equipment, effectively reduce leakage at pipeline interfaces, and reduce the workload of on-site pipeline maintenance.

[0048] V. The piping design and laying method of this cold rolling mill uses clamps to fix the pipeline, which can be installed on site and effectively improves the flexibility of pipeline adjustment.

Furthermore, in the description of this application, unless otherwise stated, "multiple" means two or more.
