Embodiment 1
[0148] The internal grade corresponding to an order: S09410;
[0149] The units involved in the thickness measurement are: APL (normalization)-RCM (twenty-roll mill)-CA_CL2 (finished product annealing)-CS_CL2 (recoiling)
[0150] Using the forward-to-back calculation method, the following information is obtained:
[0151] (1) Designated thickness of hot rolling: 2.3mm
[0152] (2) Negative deviation rolling amount: 0
[0153] (3) Order thickness: 0.35
[0154] According to the information in (1)~(3), the final results of each process / unit after calculation are as attached image 3 ~ attached Figure 6 Shown:
[0165] The internal grade corresponding to an order: S12110;
[0166] The passing unit involving width is: APL (normalization)-PL_TCM (acid rolling unit)-CA_CL2 (finished product annealing)-CS_CL2 (heavy coil)
[0167] Using the calculation method from front to back, first obtain the specified width of hot rolling according to the order width:
[0168] (1) Order width: 1237mm;
[0169] (2) Specified width of hot rolling: 1275mm;
[0170] Then according to the above width information, further obtain other width production information:
[0171] (3) APL trimming amount: 0
[0172] (4) PL_TCM necking amount: 4
[0173] (5) PL_TCM trimming amount: 0
[0174] (6) CS_CL2 trimming amount: 34
[0175] According to the information in (1)~(6), calculate the entrance and exit widths of each process / unit in turn, and the final expanded results are as attached Figure 8 ~ attached Figure 11 Shown:

Abstract
The invention discloses a system for dynamically designing a fixed size. The system comprises an acquisition module, a first thickness determining module and a first width determining module, whereinthe acquisition module is used for acquiring order information and cold rolling process information of strip steel, the order information comprises a type, an order width and an order thickness of thestrip steel, the cold rolling process information comprises preset units which strip steel plans to pass, width production information and thickness production information, the first thickness determining module is used for determining a corresponding inlet thickness and a corresponding outlet thickness of the strip steel on each preset unit according to the thickness production information and aproduction sequence of the strip steel in a cold rolling process section from front to back, and the first width determining module is used for determining a corresponding inlet width and a corresponding outlet width of the strip steel on each preset unit according to the width production information and the production sequence of the strip steel in the cold rolling process section from front toback. According to the system, the accuracy of strip steel sizing calculation is improved, and the system is more suitable for an order production mode with many personalized demands and small-batch ordering.
Description
technical field [0001] The present application relates to the technical field of cold rolling, in particular to a system for dynamic design and sizing. Background technique [0002] Geometric dimensions are the main indicators for strip production. In addition to good performance and surface quality, geometric dimensions that meet user needs are also key items in product development. In the rolling process, different rolling reductions can produce chilled coils of different specifications, which will also affect the production capacity and product performance of the rolling mill. In each process stage of cold rolling, reasonable thickness design and width design, not only Affecting the horizontal thickness difference level of the finished product also has an important impact on the comprehensive yield. Therefore, the dynamic design of the thickness and width of cold-rolled and hot-rolled raw materials is particularly important for strip production. [0003] The traditiona...
