Embodiment 1
[0148] Internal grade corresponding to an order: S09410;
[0149] The passing units involving thickness are: APL (normalization)-RCM (twentieth-high mill)-CA_CL2 (finished annealing)-CS_CL2 (re-rolling)
[0150] Using the forward-backward 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 from (1) to (3), the final development results of each process / unit after calculation are as follows image 3 ~attached Image 6 shown:
[0165] Internal grade corresponding to an order: S12110;
[0166] The passing units involving the amount of width are: APL (normalization) - PL_TCM (acid rolling combined unit) - CA_CL2 (finished annealing) - CS_CL2 (re-rolling)
[0167] Using the calculation method from front to back, first obtain the specified width of hot rolling according to the width of the order:
[0168] (1) Order width: 1237mm;
[0169] (2) The 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 from (1) to (6), the inlet and outlet widths of each process / unit are calculated in turn, and the final expansion results are shown in the appendix. Figure 8 ~attached Figure 11 shown:

Abstract
The invention discloses a system for dynamic design and sizing, comprising: an acquisition module for acquiring order information of strip steel and cold rolling process information; the order information includes strip type, order width and order thickness; cold rolling process information Including the preset unit, width production information and thickness production information that the strip is going to pass through; the first thickness determination module is used to determine the strip in the cold rolling process section according to the thickness production information and the production sequence of the strip from front to back in the cold rolling process section. The inlet thickness and outlet thickness of each preset unit; the first width determination module is used to determine the strip in each preset unit according to the production sequence of the strip in the cold rolling process section from front to back according to the width production information Inlet width and outlet width on. The above-mentioned system improves the accuracy of strip steel sizing calculation, and is more suitable for the order production mode with many personalized demands and small batch orders.
Description
technical field [0001] The present application relates to the technical field of cold rolling, and in particular, to a system for dynamic design and sizing. Background technique [0002] Geometry is the main indicator of strip production. In addition to good performance and surface quality, geometric dimensions that meet user needs are also a key item in product development. In the rolling process, different rolling reduction rates can produce different specifications of cold hard coils, 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 It affects the horizontal thickness difference level of the finished product and also has an important influence 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 trad...
