Description

Technical Field

[0001] The present invention belongs to the field of intelligent production of steel enterprises, and specifically relates to a device and method for matching multiple plate types of composite / stack-rolled billet substrates with coordinated sub-plates. Background Art

[0002] In the production process of steel enterprises, when the finished product contract sub-plate is thin and single-layer billet rolling is difficult, the enterprise solves this problem by stacking the composite / stacked billet substrate. Currently, some steel enterprises have launched this business, but the composite / stacked billet substrate contract matching is manually designed, and its disadvantage is low efficiency. It is not only difficult to reduce costs and increase efficiency, but also difficult to solve the problem of large business volume.

[0003] At present, domestic steel enterprises use the MES system developed by Baosight and the Posco MES system of South Korea. The old version of the former does not have this patent function, and the new version has limited plate types and requires manual initial cutting points. The old version of the latter only has manual design functions, and the new version implements technical blockade. Therefore, it is necessary to develop the composite / stacked rolling billet design function of the MES system of steel enterprises, which can well meet the needs of enterprises. Summary of the invention

[0004] In view of the technical problem that the existing MES system of steel enterprises lacks the function of coordinated contract matching of multiple plate types of composite / laminated billet substrates, the present invention proposes a composite / laminated billet multiple plate type coordinated contract sub-plate matching device and method to realize the intelligent matching function of composite / laminated billet substrates in the MES system of steel enterprises, so as to solve the problems of artificial substrate contract matching and imperfect functions in the design of composite / laminated billets.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A composite / laminated billet substrate multi-plate type collaborative contract sub-plate matching device comprises a pool collection unit for composite / laminated billet, substrate and its matching contract, a contract sub-plate matching unit for composite / laminated billet substrate, a command generation unit, an operation terminal and a server; the operation terminal is connected to a server in an MES system via a data line, the pool collection unit for composite / laminated billet, substrate and its matching contract, the contract sub-plate matching unit for composite / laminated billet substrate and the command generation unit are all connected to the server via a network interface, and when the pool collection unit for composite / laminated billet, substrate and its matching contract is started, several composite / laminated billets, substrates and their matching contracts to be designed are written into corresponding memories and displayed on a terminal interface, and when the contract sub-plate matching unit for composite / laminated billet substrate is started, the contract sub-plate matching unit for composite / laminated billet substrate is performed to match the optimal solution for the contract sub-plate of each composite / laminated billet substrate and an initial cutting position is calculated, and the command generation unit comprises a sample adding and secondary calculation component, a process heat treatment code adding component and a command generation component, so as to realize sample adding and secondary calculation for each matching solution, and finally generate and release commands.

[0007] Furthermore, the pool collection unit for the composite / laminated slab, substrate and its matching contract includes a pool collection program and a memory.

[0008] Furthermore, the contract sub-plate matching unit of the composite / laminated slab substrate includes a matching program, a base table and rule memory, and a solution memory.

[0009] The method for matching multiple plate types of composite / battery-rolled blank substrates with coordinated sub-plates using the above device comprises the following steps:

[0010] S1. "Pool Collection" Step: Receive the pool collection instruction issued by the designer from the operation terminal, the server executes the pool collection program, obtains the composite / laminated billets, base materials and their matching contracts that meet the conditions from the MES, writes them into the corresponding memory respectively, and displays them on the operation terminal interface, selects the composite / laminated billets for material confirmation, determines their base materials and their matching contracts, or selects the contract for contract confirmation, determines the composite / laminated billets and base materials associated with the selected contract, and stores the confirmed composite / laminated billets, base materials and their matching contracts into the memory;

[0011] S2. "Cooperative board type decision" step: decompose the symmetrical or quasi-symmetrical contract into two identical contract subsets, call the "board type decision method" to determine the collaborative board type matching the substrate contract, that is, a combination of A1-A2, S1-S2 or G, and the contract sub-board matching schemes of several substrates have the same initial cutting point, and store them in the scheme memory;

[0012] S3. "Base material contract matching scheme optimization design" step: for the composite / lap-rolled billet base material and its contract, based on the given plate type, the super-inspired base material contract collaborative optimization method is used to design the optimal matching scheme, and the initial cutting position of the large plate after rolling is calculated;

[0013] S4. Accurately calculate the sample for the optimal matching solution, add process detection and heat treatment, generate 5 major command information (command composite / laminated billet information, command substrate information, command large plate information, command small plate information, command parameter information), and then transmit it to the production site through the MES system.

[0014] Furthermore, if an exception occurs during the design process, the "intelligent error handling" is called to display the cause of the failure and related information on the front end for the designer to perform base table maintenance and exception handling.

[0015] Furthermore, the analysis and judgment method of symmetry and quasi-symmetry in S2 specifically includes the following steps:

[0016] (1) Symmetry means that the base material thickness of the composite / battery-rolled billet is the same, the base material matches all the contract shortfalls and can at least equally divide the base material number, and the yield rate meets the given requirements;

[0017] (2) Quasi-symmetry means that when the base material thickness of the composite / bamboo billet is the same, the base material matching does not satisfy the symmetry, or when the base material thickness of the composite / bamboo billet is different, the optimal solution obtained by base material matching meets the yield requirement and has the same initial cutting point;

[0018] (3) If the first condition in (1) does not hold, then separate the corresponding contract subsets according to all contracts associated with the substrate. If the third condition in (1) does not hold, separate the associated contract subsets of each substrate according to the operator's preference. If only the second condition in (1) does not hold, then merge the contracts within a given threshold range based on the volume ratio.

[0019] Furthermore, the board type decision method in S2 specifically includes the following steps:

[0020] (a) For each base material of the composite / battery-rolled billet, the infinite norm, infinitesimal norm and 1 norm of the width component of the contract subset are calculated, and the ratio of the base material length to the infinite norm and 1 norm of the width component of the contract subset is calculated respectively;

[0021] (b) Given two integers of different sizes, divide the horizontal axis into three adjacent intervals, including the left interval, the middle interval, and the right interval;

[0022] (c) If the ratio of the length of the substrate to the width of the contract subset falls within the left interval and the infinite norm is equal to the infinitesimal norm, the plate type is A1; if the maximum and minimum norms are not equal, the plate type is A2;

[0023] (d) If the ratio of the length of the substrate to the width component of the contract subset falls in the middle interval and the infinite norm is equal to the infinitesimal norm, the plate type is S1; if the maximum and minimum norms are not equal but the number of contract outstanding is not less than the given number, the plate type is S2;

[0024] (e) If the ratio of the base material length to the contract subset width component falls in the right interval, or in the middle interval and the number of contract shortages is less than the given number, the board type is G.

[0025] Furthermore, the super-inspired substrate contract collaborative optimization method in S3 specifically includes the following steps:

[0026] (i) Analyze whether the substrate contract match is a symmetrical match or a quasi-symmetrical match. If it is a symmetrical match, divide the number of outstanding contracts of the several substrate matches by the number of substrates. Otherwise, perform quasi-symmetrical processing on the contracts and obtain the matched contracts one by one.

[0027] (ii) calling the plate type decision method to determine the plate type that matches the current substrate with the contract, and using the plate type and the contract attributes to obtain the head cut, tail cut, side cut, thickness addition, and sample length;

[0028] (iii) According to different plate types, the corresponding hyper-heuristic construction method is called to construct the optimal matching solution, and the size of the rolled product is calculated using the obtained head and tail cutting amount, side cutting amount, thickness addition amount and sample length, and the slab size and yield rate of the matching substrate are reversely calculated using the substrate cross section;

[0029] (iv) If it is a symmetric match, the obtained slab plan will be copied to other substrates. If it is a quasi-symmetric match, the matching plans for other substrates will be calculated block by block in turn. The initial cutting position when the length of the rolled piece is greater than the threshold will be determined according to the plate type and added to the plan. Finally, the matching plan will be stored in the plan memory.

[0030] Furthermore, the hyper-heuristic construction method in (iii) constructs the optimal matching solution, which means that when a substrate can be matched with multiple contracts and each contract has enough missing parts to match the substrate, the optimal solution can be selected by satisfying the number of contracts and achieving the optimal yield rate, so as to meet the designer's requirements and achieve the optimal yield rate.

[0031] Furthermore, "intelligent error handling" includes: when a certain base material does not match the contract during pool collection, the specific reason is inferred through the contract attributes; when obtaining parameters, no records that meet the conditions are found, and the designer is guided to perform base table maintenance and exception handling by providing solutions and matching contract related information; when the optimal matching solution does not meet the designer's requirements, the system reminds the designer to draw a panel assembly solution diagram, and constructs the optimal solution that meets the designer's requirements by identifying the solution diagram.

[0032] The beneficial effects of the present invention are:

[0033] The present invention can realize the composite / laminated slab design function of the MES system of steel enterprises, and at the same time solve the problems of artificial base material contract matching and imperfect functions in the composite / laminated slab design, thereby improving the design efficiency and automation level and reducing enterprise costs.
