Description
Technical Field
The application relates to the technical field of plate rolling, in particular to a process design method for plate rolling.
Background
In the current process of rolling and producing plate and strip, such as rolling and producing steel plates, customers obviously require the type, specification and single weight of products in orders, and the ordering requirements of the customers are more diversified. Although in the plate rolling process, the cold rolling unit can perform coil splitting and edge cutting according to the requirements of customers, in the process of producing the plate blank by continuous casting, because the production capacity determines that the specification and the weight of the raw material plate blank can not be flexibly changed, if the specification and the weight of the plate blank change frequently, not only the continuous casting and hot rolling production rhythm is seriously influenced, but also the product quality is defective. Therefore, in the production process of a steel mill, the specification and the weight of the raw material plate blank are relatively centralized and stable, so that the requirements of production capacity and orders need to be integrated, and on the premise of meeting the production principle of the steel mill, the weight and the specification of the plate blank are comprehensively determined to meet the requirements of the orders to the maximum extent.
The weight and specification of the slab are generally roughly calculated and determined manually at present, and are generally obtained by adding 100-200mm to the order width as the slab width and then manually obtaining the slab weight according to the order weight target value and the comprehensive yield estimation value of the sheet. Then, the orders are classified according to the finished product sizes and the single weight requirements of the multiple orders, then a certain type of centralized steelmaking plan is selected, no specific order is corresponding in the slab production process, and production is arranged according to the issued plan. And after the slab is produced, according to the actual weight of the slab and the specific requirements of the order, manually determining the corresponding specific customer and the order.
However, the weight and specification of the slab cannot be calculated quantitatively, accurately and stably by manual experience: the weight and specification of the slabs calculated by different personnel according to the same order are different according to the difference of experiences, and the data sources based on manual calculation are different, so that the calculation accuracy is questionable and the calculation errors are easy to generate. Inaccurate calculation of slab specification and weight will result in the slab failing to meet the order requirement, thus causing overstock of stock, or causing a great deal of economic loss due to cutting loss or transferring to spot sale in downstream processes. On the other hand, with the continuous improvement of the on-site production capacity and the expansion of the production specification, the prior experience often becomes to limit the full exertion of the production line capacity, so that the production line capacity is actually available, but the manual calculation is not considered, so that the production line capacity is wasted. In summary, a new technical design solution for rolling plates is needed to improve the calculation efficiency and calculation accuracy of the specification and weight of a plate blank, reduce economic loss caused by manual calculation errors, and improve the production capacity of a plate unit.

Detailed Description
In order to make the present application more clearly understood by those skilled in the art to which the present application pertains, the following detailed description of the present application is made with reference to the accompanying drawings by way of specific embodiments.
The method aims to solve the problems that the calculation efficiency and the calculation precision are low due to the fact that the specifications and the weights of the slabs are calculated manually by experience, estimated slabs cannot meet the order requirements easily, stock overstock is caused, or the slabs are hung in order forcibly, and then cutting damage or spot goods selling is carried out in a downstream process. In an alternative embodiment, as shown in fig. 1, the inventor proposes a process design method for rolling a plate, which obtains relevant parameters through programming in a production and marketing system, and accurately calculates the specification and weight of a plate blank according to order information, and can give consideration to order requirements and production line capacity, and accurately calculate the specification and weight requirements of the required plate blank according to the principle that the maximum cost of a product is the lowest. The whole idea is as follows:

s2: the production and marketing system confirms the plate specification control parameters corresponding to the order information according to the plate variety and the order width;
s3: the production and marketing system determines the target width range and the rated target width of the plate blank of the plate according to the order width and the plate specification control parameters;
s4: the production and marketing system determines the target weight range of the plate blank according to the target width range of the plate blank;
s5: the production and marketing system determines a slab target length range and a slab rated target length according to the slab target weight range and the slab target width range;
s6: and the production and marketing system sends the slab target weight range, the slab target width range, the slab target length range, the slab rated target width and the slab rated target length to the manufacturing execution system so that the manufacturing execution system controls the production and the manufacturing of the plates according to the parameters.
Specifically, at present, iron and steel manufacturing enterprises are all configured with a whole set of software schemes for enterprise resource planning ERP, and sales personnel can receive and manage customer orders through a production and sales system, form contract information according to the customer orders, and issue the contract information to a manufacturing and execution MES system for scheduling and executing production plans. When contract information is generated in the production and marketing system, the specification and weight of the slab need to be calculated according to the order requirements of customers. In this embodiment, the slab refers to a continuous casting slab produced by continuous casting, and the plate is a hot rolled coil or a cold rolled coil rolled in subsequent hot rolling or cold rolling. The sheet specification design capability in S1 refers to the range of production capability of the length, width and thickness of the slab and sheet determined by the continuous casting, hot rolling and cold rolling mill train, wherein the thickness of the slab is usually fixed and not calculated, and the rest specification parameters need to be calculated; the plate weight design capability refers to the weight capability range of the plate blank or the plate which can be produced by a continuous casting, hot rolling and cold rolling unit, such as the design weight range of the plate blank, the design weight bearing range of a crane for hoisting the plate blank, and the like. The sheet specification control parameters in S2 are sheet rolling production specification control amounts predetermined according to the specific sheet type and the order width, such as the amount of edge cutting, the amount of narrowing, the maximum constant width amount of hot rolling, the target constant width amount of hot rolling, the maximum widening amount of hot rolling, and the like of each process of the sheet. And when the new order enters the production and marketing system, the production and marketing system generates a product code according to the input board variety and width, and then automatically acquires the board specification control parameters corresponding to the product code. After acquiring the data in S1 and S2, the production and marketing system automatically calculates the target specification and target weight of the slab according to the steps of S3 to S5, automatically fills the calculation result in contract information, and issues the contract information to a Manufacturing Execution System (MES) for specific production planning.

The embodiment provides a process design method for rolling plates, which is used for automatically and comprehensively calculating the target weight and the target specification of a plate blank according to order information and production capacity parameters of a plate production unit by secondary development in a production and marketing system. The automatic calculation in the production and marketing system can overcome the uncertainty caused by the influence of experience on manual calculation, avoid calculation errors, ensure that the calculation data sources are uniform and reliable, and simultaneously improve the efficiency and the accuracy of slab specification and weight calculation, thereby avoiding the stock backlog and the product economic loss caused by the calculation errors.
The following describes in detail a specific slab weight and gauge calculation method, based on the same inventive concept of the previous embodiment, and in another alternative embodiment, the above-mentioned sheet gauge control parameters include: the method comprises the steps of performing whole-process trimming on a plate by q, narrowing by p, performing hot rolling by g to obtain a maximum fixed width, performing hot rolling by a target fixed width by s, and performing hot rolling by j to obtain a maximum broadening amount;
s3: the production and marketing system determines the slab target width range and the slab rated target width of the plate according to the order width and the plate specification control parameters, and specifically comprises the following steps:
s31: the production and marketing system determines the target width range W of the plate blank as W1,W2](ii) a Wherein, W1＝k+q+p-j，W2K + q + p + g; target width W of slab0∈W。
The trimming amount q is the sum of the trimming amounts of all the working procedures of the plate in the whole production process; the plate specification control parameters are predetermined according to the width change of plates of specific varieties and specifications in the plate rolling process, and the production and marketing system calls the corresponding plate specification control parameters according to the order information during calculation to comprehensively determine the target width range of the plate blank. When the target width range of the slab is determined, the calculated target width range W of the slab is required to be within the specification design capability range of the continuous casting slab, and the specification design capability of the slab is obtained from a design specification data sheet of a steelmaking process.
Optionally, nominal target width W of slab0And (5) performing slab production control according to the upper limit of the target width range of the slab as a target, and reducing the possibility of large economic loss caused by the fact that the width of the final finished product is not enough to change the spot product.
In some cases, the width of the slab needs to consider stacking of a continuous casting slab library, specific requirements are made on the rated target width of the slab, and the width promotion amount of the slab needs to be considered at the time, so that the optional plate specification control parameters further include the minimum value of the slab production width and the width promotion amount of the slab;
determining the target width W of the slab0The minimum value + i of the production width of the slab and the width promotion quantity of the slab; wherein i is such that W0≤W2The maximum integer value that holds.
That is, according to this aspect, the target slab nominal width is limited based on the width increase amount of the slabs when stacked, and when the width increase amount is satisfied, the maximum value of the target slab nominal width is set within the target slab width range.
After determining the slab width gauge, the slab target weight range should next be determined, and based on the inventive concepts of the previous embodiments, in yet another alternative embodiment, the sheet gauge design capabilities include: the thickness of the plate blank, the minimum length of the plate blank and the maximum length of the plate blank;
the plate weight design capability comprises: the method comprises the following steps of A, a slab design weight range A, a slab lifting appliance bearing range B, a slab rolling unit loading and unloading design weight range C, a slab rolling outer diameter limit slab weight range D and a slab rolling comprehensive yield e;
s4: the production and marketing system determines the target weight range of the plate blank according to the target width range of the plate blank, and specifically comprises the following steps:
s41: the production and marketing system designs the capacity according to the plate specification and determines the initial weight range of the plate blankm＝[m1,m2](ii) a Wherein m is1Slab thickness × W1× slabs producing a minimum length × steel density, m2Slab thickness × W2× maximum length of slab production × steel density;
s42: determining a slab target weight range M ═ M1,M2]Wherein M is A ∩ B ∩ C/e ∩ D ∩ M.
Specifically, the weight design capacity is determined by a unit, the weight design capacity of each process can be obtained in the design specification of each process, for example, the slab design weight range A is the weight design capacity of a slab subjected to continuous casting smelting, A ═ x ∈ R | A1 ≦ x ≦ A2}, and can be obtained in the design specification of a steel making process, the slab sling load bearing range B refers to the lifting weight design capacity of a crane for lifting the slab, C is the design weight range in the slab rolling process, and can be obtained in the steel rolling design specification, the slab weight range is converted into the weight range of the slab, the influence of the comprehensive yield e needs to be considered, the comprehensive yield e of each type of slab is comprehensively determined according to the actual specification of the slab, the head and tail cutting amount of the slab in the corresponding production process, C/e is the weight range of the slab corresponding to the upper and lower line design weight ranges of the slab, D is the allowable steel coil weight range determined according to the outer diameter limit of the upper line of the slab rolling unit, for example, when the outer diameter of the steel coil is 2.2 meters, the weight range of the slab is successfully calculated according to the lower line of the steel rolling system, and the comprehensive yield range of the slab can be calculated according to the comprehensive lower line, the comprehensive weight range of the comprehensive yield range of the steel slab.
When the target weight range of the slab is determined, the initial weight range M of the slab is calculated according to the target width range W of the slab determined in the process and the minimum value and the maximum value of the production length of the slab specified in the design specification of the steelmaking process, and then the intersection of the weight ranges A, B, C/e, D and M is taken according to the collective calculation method, namely the target weight range M of the slab should meet the requirements of the weight ranges A, B, C/e, D and M at the same time.
After the target width range W and the target weight range M of the slab are determined, since the thickness of the slab is fixed, the target length range of the slab should be confirmed next. Therefore, based on the same inventive concept of the previous embodiment, in yet another alternative embodiment, the S5: the production and marketing system determines a slab target length range and a slab rated target length according to the slab target weight range and the slab target width range, and specifically comprises the following steps:
s51: determining the target length range L of the plate blank as L1,L2]Wherein: l is1＝M1/(slab thickness × W2)；L2＝M2/(slab thickness × W1)；
S52: determining the target length L of the slab0＝M2/(slab thickness × W0)。
Wherein the target slab length is controlled according to an upper limit of the length range.
Some customers consider the requirements of their own processing line or transportation, and explicitly require the sheet weight of the coil in the order, and even the sheet weight range required by some orders is small. For such orders, the splitting treatment needs to be carried out in the production process, and in order to accurately split the small rolls with the single weight required by customers, the inventor provides a splitting principle of 'splitting with the largest coil weight after splitting' through research so as to reduce the economic loss caused by the splitting error as much as possible. Thus, based on the same inventive concept as the previous embodiment, in another alternative embodiment, the order information further includes a single roll weight range h ═ h1,h2](ii) a Wherein h is1Is the minimum weight of a single roll, h2Is the maximum weight of a single roll, h2<m1；
At S42: determining a slab target weight range M ═ M1,M2]Then, the method further comprises the following steps:
