It should be noted that, the execution body in this embodiment may be an element selection device applied to the metallurgical field, where the element selection device applied to the metallurgical field may be a computer device having a data processing function, or may be other devices that may implement the same or similar functions, which is not limited in this embodiment, and in this embodiment, a computer device is described as an example. It will be appreciated that the component-selection method applied to the metallurgical field proposed in this embodiment may be executed by the processor as a separate component-selection function module, and may also be executed by the processor as one of the component-selection function modules in the metallurgical field modeling software. The present embodiment is not limited thereto.

In an embodiment, searching for standard connection elements in a preset database based on preset rules includes: determining spatial position information and a connecting element form according to a preset rule; and searching a standard connection element conforming to a preset geometric matching connection mode in a preset database based on the space position information and the connection element form.

Specifically, the present embodiment is described taking a preset rule including spatial position information and a connection element form as an example. The preset rules can also be set according to the actual conditions of other metallurgical field process factories. For example, the geometrically adapted connection elements can be adapted in a predetermined database based on the spatial position and the connection element form. The connection element forms include, but are not limited to, tee, branch, elbow, etc. connection forms.

It should be noted that the preset database includes, but is not limited to, various types of pipes, elbows, tees, reducer pipes, caps, flanges, valves, and other elements and their attributes. Illustratively, for example, the special-shaped pipeline is provided with a pipeline code of 02-CFG 2600 multiplied by 2150, 02 is an industrial steelmaking process system which is regularly adapted from an enterprise database, the CFG is a dedusting air pipe, and the specification of 2600 multiplied by 2150 is judged to be a secondary flue gas dedusting air pipe; identifying that a rectangular pipe of 2100 x 1800 is to be connected to it, the connection standard element includes: elbow (attributes include type, angle, length x width, bend radius R, wall thickness), reducer (attributes include type, length x width before reducing/length x width after reducing, length L, wall thickness δ), tee (attributes include type, main pipe length x width, branch pipe connection angle/mode), etc.

In an embodiment, when the standard connection element is not found in the preset database, determining starting position requirement information according to the preset rule; determining a target element size based on the initial position requirement information, and generating a nonstandard connector according to the target element size; and generating an integral pipe network model according to the nonstandard connecting piece.

It will be appreciated that the preset rules include spatial position information, and the limited space causes the element size of the standard connection element not to fit the spatial position, so that the standard connection element is not found in the preset database, and at this time, starting position requirement information (including the target element size suitable for the spatial position) is determined according to the preset rules, and a nonstandard connection piece with a size conforming to the starting position requirement is generated, where the nonstandard connection piece is a size specification temporarily not existing in the standard database, and is created as a nonstandard piece. For example, for the above identified non-standard pipe CFGs 2600×2150 and 2100×1800 pipe connections, if no standard connection is found in the database, a spatial reducer connection is generated according to the spatial position, and if the spatial position connection cannot be achieved only by the reducer, the connection is completed in a matched "spatial elbow+reducer" combination. If the connection is successful, the creation of the nonstandard elbow and the nonstandard reducing pipe is completed.

In an embodiment, after determining a target element size based on the starting position requirement information and generating a nonstandard connection according to the target element size, the method further comprises: judging whether the nonstandard connecting piece is a plurality of pieces or not; when the nonstandard connectors are multiple, the nonstandard connectors are subjected to priority ranking to obtain ranking results; displaying the sorting result based on a preset display terminal; and when receiving a selection confirmation instruction fed back based on the sequencing result, determining the corresponding nonstandard connector according to the selection confirmation instruction.

It should be noted that, generating non-standard connectors with a consistent size according to the initial position requirement, when the non-standard connectors have multiple types of adaptation forms, the non-standard connectors can be ordered according to the recommended priority and displayed on a preset display terminal such as a computer, and the designer confirms to select the non-standard connectors, so that the accuracy and the uniqueness of the non-standard connector types can be improved. When a confirmation instruction fed back by a designer is not received within a certain time, the computer can select the nonstandard connection piece with the highest priority by default according to the recommended priority ranking.

In one embodiment, an integral pipe network model is generated from the nonstandard connectors. Specifically, pipeline examples for generating the pipe network model may be preset, one pipeline example may correspond to one type of pipeline, and the classification standard and the type refinement degree of the pipeline type may be set according to actual requirements. For example, pipelines of the same system and the same function can be classified into the same class, and pipeline network modeling can be realized by one pipeline instance code of the same class. Specifically, the nonstandard connectors can be connected according to a preset pipeline example to generate an integral pipe network model.

By combining the positioning of the main pipe and the branch pipe to be connected in the geometric space of the model, the angle, the length and the eccentric displacement of the connecting pipe fitting are automatically adapted according to the determined nonstandard connecting piece form, and the intelligent matching of the input limiting conditions to the optimal path is also supported. For example, the finished standard component matching connection is preferentially called for the high-temperature and high-pressure steam pipeline or the pipeline of the key system and the area; for non-standard, normal or low pressure ventilation ducts, the single, shortest path connection is preferred.

In an embodiment, under a preset design condition, performing parameter verification on the integral pipe network model includes: determining the region code of the design project based on the region information of the design land parcel model; determining an industry universal standard corresponding to a process system to which the pipeline belongs according to the region code; determining a preset rigidity range, a preset stress range and a preset resistance loss range of the pipeline according to the industry universal standard; under a preset design working condition, carrying out stress analysis and loss resistance verification on the integral pipe network model to obtain stiffness parameters, stress parameters and loss resistance parameters; comparing the rigidity parameter, the stress parameter and the resistance loss parameter with a preset rigidity range, a preset stress range and a preset resistance loss range of the pipeline respectively to obtain a comparison result; and determining whether to perform parameter compensation on the integral pipe network model according to the comparison result.

It will be appreciated that the specific items of parameter verification in this embodiment are described by taking stiffness, stress and resistance as examples. The specific item of parameter verification may also be set according to the actual conditions of other metallurgical process factories, which is not limited in this embodiment. When the integral pipe network model fails to pass the parameter verification, parameter compensation is required to be carried out on the integral pipe network model according to a preset compensation rule, wherein the preset compensation rule comprises at least one of rigidity compensation, stress compensation and loss resistance compensation.

Specifically, the connected pipe system is used as an integral pipe network model, corresponding industry universal standards, such as national standard GB and/or ASME specifications, are selected according to the region to which the project belongs and the process system to which the pipeline belongs, and the dangerous parts (such as the connection part of the pipeline and the element) of the integral pipe network model are subjected to stress analysis under the condition of reading (preset design conditions including but not limited to temperature, pressure, medium, pipeline specification, material and the like) by calculation.

Illustratively, the force analysis includes, but is not limited to, determining stress S of the pipe and element as a combination of longitudinal forces, bending moments, and torques resulting from sustained loads (e.g., pressure and gravity) and occasional loads (e.g., wind or earthquake) _1，2 ≤1.33S _h (e.g., the allowable stress of the material for the temperature can be calculated). By way of example, the support and hanger and other constraint positions and types on the pipeline are added simultaneously, material performance parameters at the working temperature are called, displacement strain and bending stress generated by load, vibration, thermal expansion and contraction and constraint of the support are calculated, and whether the comprehensive stress is smaller than the allowable stress is checked. And calculating resistance loss in the section of integral pipe network model by calling common flow velocity of the fluid medium and combining pipeline specification, pressure and the like to obtain a resistance loss parameter, and checking whether the pressure parameter at an outlet meets the process requirement.

In an embodiment, after performing parameter verification on the overall pipe network model under a preset design working condition, the method further includes: when the integral pipe network model passes parameter verification, the nonstandard connecting piece is used as a target connecting piece; and generating and displaying a pipeline three-dimensional model according to the target connecting piece.

It should be noted that, under the preset design condition, parameter verification is performed on the whole pipe network model, when the whole pipe network model passes the parameter verification, a pipeline three-dimensional model, namely the whole pipe network model, is generated according to the target connecting piece, and the whole pipe network model is subjected to drawing and discharging.

In an embodiment, when the integral pipe network model passes the parameter verification, after the nonstandard connection piece is used as the target connection piece, the method further comprises: determining a target category form and a target size of the target connection; searching a corresponding element case collection in the preset database based on the target category form; writing the target connector and the target size into the element case set to update the preset database.

If the above-mentioned parameters of rigidity, stress and resistance meet the standard and technological requirements, it may indicate that the non-standard connection piece generated intelligently meets the requirements, and the dimensions of the non-standard connection piece may be reversely written into the preset database according to the category form of the non-standard connection piece to update the preset database for the next call.

It should be noted that, referring to fig. 3, when a standard connection element is found in a preset database, the standard connection element is automatically matched and connected to generate an integral pipe network model; and under the preset design working condition, parameter verification is carried out on the integral pipe network model, and when the integral pipe network model passes the parameter verification, namely, the parameter verification calculation of rigidity, stress and resistance meets the standard and the process requirement, and the integral pipe network model carries out drawing discharging.

It will be appreciated that in the above steps, the designer may instruct the editing operation to be performed on the overall pipe network model. Among other things, editing operations include, but are not limited to, create, select, modify, delete, and move. The editing operations performed are specifically determined by designer instructions, including information determined by the needs of the designer or design project. For example, on the basis of the built integral pipe network model, the model part can be modified and added according to the instruction of a designer, so that the updated integral pipe network model can be quickly obtained, the manual workload can be effectively reduced, the modeling period can be reduced, and the integral pipe network model built by the mode has the advantages of low manufacturing cost and high accuracy.

According to the embodiment, standard connection elements are searched in a preset database based on preset rules; when the standard connecting element is not found in the preset database, determining initial position requirement information according to the preset rule; determining a target element size based on the initial position requirement information, and generating a nonstandard connector according to the target element size; generating an integral pipe network model according to the nonstandard connecting piece; under a preset design working condition, parameter verification is carried out on the integral pipe network model; and when the integral pipe network model fails to pass the parameter verification, reinforcing or compensating the nonstandard connecting piece according to a preset compensation rule to obtain a target connecting piece. In this embodiment, the standard connection element can be quickly and accurately matched based on the preset database, and the nonstandard connection element can be generated when the standard connection element is not found. And performing verification compensation and the like on the integral pipe network model to obtain nonstandard connectors meeting all standards and process requirements, improving the applicability of the nonstandard connectors, and building a complete pipe network three-dimensional model by perfecting and supplementing the nonstandard connectors so as to build the pipe network three-dimensional model according to the nonstandard connectors to realize three-dimensional visualization of metallurgical process factory data, thereby solving the technical problems of high error-prone performance and low modeling efficiency of the existing metallurgical process factory data modeling mode.

In some embodiments, as shown in fig. 4, a second embodiment of the element selection method applied to the metallurgical field according to the present invention is proposed based on the first embodiment, and the step S500 includes:

step S501: determining the region code of the design project based on the region information of the design land parcel model;

step S502: determining an industry universal standard corresponding to a process system to which the pipeline belongs according to the region code;

step S503: determining a preset rigidity range, a preset stress range and a preset resistance loss range of the pipeline according to the industry universal standard;

step S504: under a preset design working condition, carrying out stress analysis and loss resistance verification on the integral pipe network model to obtain stiffness parameters, stress parameters and loss resistance parameters;

step S505: comparing the rigidity parameter, the stress parameter and the resistance loss parameter with a preset rigidity range, a preset stress range and a preset resistance loss range of the pipeline respectively to obtain a comparison result;

step S506: and determining whether to perform parameter compensation on the integral pipe network model according to the comparison result.

Specifically, the embodiment is described by taking specific items of parameter verification including rigidity, stress and resistance loss as examples.

It can be understood that the connected pipe system is taken as an integral pipe network model after the pipe system is selected, corresponding industry universal standards, such as national standard GB and/or ASME specifications, are selected according to the region to which the project belongs and the process system to which the pipeline belongs, and the dangerous parts (such as the connection part of the pipeline and the element) of the integral pipe network model are subjected to stress analysis under the condition of reading (preset design conditions including but not limited to temperature, pressure, medium, pipeline specification, material and the like) by calculation.

Illustratively, the force analysis includes, but is not limited to, determining whether the pipe and element are loaded by constant loading (e.g., pressure and gravity) and occasional loadingStress S of combination of longitudinal force, bending moment and torque generated by load (such as wind or earthquake) _1，2 ≤1.33S _h (e.g., the allowable stress of the material for the temperature can be calculated). By way of example, the support and hanger and other constraint positions and types on the pipeline are added simultaneously, material performance parameters at the working temperature are called, displacement strain and bending stress generated by load, vibration, thermal expansion and contraction and constraint of the support are calculated, and whether the comprehensive stress is smaller than the allowable stress is checked. And calculating resistance loss in the section of integral pipe network model by calling common flow velocity of the fluid medium and combining pipeline specification, pressure and the like to obtain a resistance loss parameter, and checking whether the pressure parameter at an outlet meets the process requirement.

In an embodiment, determining whether to perform parameter compensation on the whole pipe network model according to the comparison result includes: determining that the rigidity parameter does not accord with the preset rigidity range according to the comparison result, and determining a rigidity compensation amount according to the rigidity parameter and the preset rigidity range; calling a rigidity compensation form corresponding to the rigidity compensation amount based on a case library, and performing rigidity compensation on the integral pipe network model according to the rigidity compensation form; determining that the stress parameter does not accord with the preset stress range according to the comparison result, and performing stress compensation by increasing the bending radius of the existing elbow in the pipe system or adding natural compensation such as pi-type compensation according to the stress parameter and the preset stress range; determining that the resistance parameter does not accord with the preset resistance range according to the comparison result, and determining the resistance compensation quantity according to the resistance parameter and the preset resistance range; based on the natural compensation mode, the allowable stress range still cannot be met, and the consideration that pi-type compensation can further increase the resistance loss is additionally arranged, the corresponding compensator can be called according to the comparison result based on the comparison of the comprehensive compensation amount in the case library, and the stress and resistance loss compensation verification is carried out on the integral pipe network model according to the comprehensive compensation amount parameters of the compensator.

The method includes the steps of determining that an integral pipe network model does not pass parameter verification according to a comparison result, and performing parameter compensation on the integral pipe network model. For example, if the calculation is not passed, natural compensation such as bending radius of the existing elbow or additionally arranging n-type compensation in the pipe system is increased according to the calculation result that the pass reinforcement and the thermal stress which are not passed are not met, or different types of compensators are added to compensate deformation amounts such as transverse, axial and angular displacement.
