[0025] Next, the present application will be described in detail with reference to the accompanying drawings.

[0026] See also Figure 1 .

[0027] Figure 1 A simplified flow chart of a quality design method for edge trimming of a steel coil in an embodiment of the present application is shown. The method may include steps S101-S103:

[0028] Step S101, establishing a steel coil edge trimming method coding table, wherein the steel coil edge trimming method coding table includes at least one steel coil edge trimming method and a corresponding independent code.

[0029] Step S102, establishing a basic table of trimming quantities, wherein the basic table of trimming quantities includes trimming information of different steel grades in each trimming unit.

[0030] Step S103, identifying the trimming delivery contract, and determining the target trimming unit that actually performs trimming and the trimming amount corresponding to the target trimming unit according to the steel coil trimming method coding table and the trimming amount base table.

[0031] Wherein, the trimming delivery contract records at least one independent code in the steel coil trimming method coding table.

[0032] In one embodiment of the present application, the steel coil trimming method coding table may include the following steel coil trimming methods: no trimming; pickling or pickling trimming, trimming in the pickling or pickling process; post-processing line trimming, if the trimming capacity of the post-processing line unit is exceeded, it is pushed forward to the pickling or pickling process unit for trimming; both pickling or pickling and post-processing lines are trimmed, and both the pickling or pickling process and the post-processing line process are trimmed; re-coiling trimming, if the trimming capacity of the post-processing line unit is exceeded, it is pushed forward to the pickling or pickling process unit for trimming; hot-rolled cross-cutting trimming, suitable for hot-rolled products; special trimming; longitudinal cutting.

[0033] In the present application, various edge trimming methods can be standardized by establishing a steel coil edge trimming method coding table, and when determining the edge trimming delivery contract, an independent code can be determined on the edge trimming delivery contract to determine a edge trimming method.

[0034] In one embodiment of the present application, the trimming information of different steel grades in each trimming unit may include: the lower limit and upper limit of thickness of the trimming unit; the lower limit and upper limit of width of the trimming unit; the lower limit and upper limit of tolerance band of the trimming unit; and the trimming amount of the trimming unit.

[0035] In one embodiment of the present application, the method further comprises: changing and maintaining the trimming amount of each trimming unit in the trimming amount base table according to the actual trimming capacity of each trimming unit.

[0036] In this application, because each trimming unit is prone to change in trimming amount due to production wear, and as production technology improves, the trimming capacity of each trimming unit will also change accordingly. Therefore, in order to meet actual production needs as much as possible, the corresponding trimming amount can be updated according to the actual trimming capacity of each trimming unit, making the entire trimming process more reasonable.

[0037] In one embodiment of the present application, the trimming amount base table also includes index numbers corresponding to the trimming information of different steel grades in each trimming unit, and the index numbers are used to identify or distinguish the trimming information of different steel grades in each trimming unit.

[0038] In this application, in order to quickly check the trimming information of different steel grades in each trimming unit, an index number can be added to the trimming quantity base table. Technical personnel in this field can use the index number when operating the trimming process or exporting information, making the process simpler.

[0039] In the present application, the index number may be a 4-digit code, the first digit being the major category code of the same steel type, and the second to fourth digits being serial numbers to distinguish different trimming information.

[0040] Table 1 shows a basic table of trimming amounts in one embodiment of the present application.

[0046] Step S201, identifying the independent code of the trimming delivery contract, and determining the target production path according to the steel coil trimming method corresponding to the independent code.

[0047] Step S202, obtaining the trimming information corresponding to each trimming unit on the target production path.

[0048] Step S203, determining a target trimming unit from each trimming unit according to the trimming information corresponding to each trimming unit and the delivery specifications of the trimming delivery contract, wherein the target trimming unit is the trimming unit that actually performs trimming on the target production path.

[0049] Step S204: selecting a target margin trimming amount of the target margin trimming unit according to the margin trimming information of the target margin trimming unit.

[0050] In this embodiment, the method for determining the target production path according to the steel coil trimming method corresponding to the independent code may include: determining the target steel coil trimming method corresponding to the trimming delivery contract according to the independent code; and selecting, from various production paths, a target production path that meets the target steel coil trimming method according to the target steel coil trimming method.

[0051] In this application, when the sales system enters a contract, a product order code is selected. The product order code may include an independent code representing whether the contract edge delivery status is trimmed or not, and identifying which trimming method is used. Then, according to the target steel coil trimming method, a target production path that meets the target steel coil trimming method is selected from various production paths. For the thickness, width, and width accuracy entered in the contract, the quality design of each trimming unit under the target production path is performed based on the independent code and the trimming information of each trimming unit, wherein the specification design involves the processing of the trimming unit and the trimming amount data.
