In other instances, well-known methods, devices, implementations, or operations have not been shown or described in detail to avoid obscuring aspects of the application.

I.e. these functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor means and/or microcontroller means.

For example, some operations/steps may be decomposed, and some operations/steps may be combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.
According to some embodiments, as illustrated in the flow diagram of fig. 1 and the flow 200 of fig. 2, the present application provides a hot rolled coil shear control method comprising: step 110, acquiring attribute data of hot-rolled coils on each hot-rolled coil attribute and an attribute data threshold of the hot-rolled coils on each hot-rolled coil attribute; step 130, sequentially judging whether the hot-rolled coil is qualified on each hot-rolled coil attribute according to the attribute data threshold and the attribute data; step 140, determining an unqualified area of the hot rolled coil if the hot rolled coil is unqualified in the corresponding hot rolled coil attribute; and 150, controlling a shearing device to shear the unqualified area of the hot-rolled coil, wherein the shearing value of the unqualified area of the hot-rolled coil does not exceed a first upper limit value.
Based on the above embodiment, step 130 includes step 120 before, and the hot rolled coil needs to be sheared from the head and tail because the head and tail of the hot rolled coil have fishtail or tongue-shaped defects after hot rolling, so step 120 shears the hot rolled coil according to the lower limit value before sequentially judging whether the hot rolled coil is qualified or not in each attribute of the hot rolled coil, and the lower limit value can be changed into any value according to actual needs.
As used herein, the hot rolled coil properties may include a hot rolled coil thickness property, a hot rolled coil width property, a hot rolled coil crown property, a hot rolled coil asymmetric flatness property, a hot rolled coil wedge property, and a hot rolled coil centerline offset property. Data of a hot-rolled coil thickness attribute, a hot-rolled coil width attribute, a hot-rolled coil crown attribute, a hot-rolled coil asymmetric flatness attribute, a hot-rolled coil wedge attribute, and a hot-rolled coil center line offset attribute of each hot-rolled coil in a production process of a hot-rolling process are collected. The acquisition method can comprise video image identification judgment data, sensor detection judgment data and the like.
The method comprises the steps of presetting qualified attribute data thresholds of a hot-rolled coil thickness attribute, a hot-rolled coil width attribute, a hot-rolled coil convexity attribute, a hot-rolled coil asymmetric flatness attribute, a hot-rolled coil wedge attribute and a hot-rolled coil central line deviation attribute before data acquisition, screening out unqualified hot-rolled coil attribute data according to the attribute data thresholds, and shearing off unqualified parts of the hot-rolled coil attribute data.
Such as: when the thickness attribute of the hot-rolled coil is not in the preset thickness value range, cutting off the part of the hot-rolled coil which is not in the preset thickness value range; when the width attribute of the hot-rolled coil is not in the preset width value range, cutting off the part of the hot-rolled coil which is not in the preset width value range; when the hot-rolled coil convexity attribute is not in the preset convexity value range, cutting off the part of the hot-rolled coil which is not in the preset convexity value range; when the asymmetric flatness attribute of the hot-rolled coil is not in the preset asymmetric flatness value range, cutting off the part of the hot-rolled coil which is not in the preset asymmetric flatness value range; when the wedge attribute of the hot-rolled coil is not in the preset wedge value range, cutting off the part of the hot-rolled coil which is not in the preset wedge value range; and cutting off the part of the hot-rolled coil which is not in the preset center line offset value range when the center line offset attribute of the hot-rolled coil is not in the preset center line offset value range. And the shearing value of the unqualified area of the hot rolled coil does not exceed a first upper limit value, and the first upper limit value can be changed into a value at will according to actual needs.
By setting the first upper limit value, waste of material due to excessive cutting is prevented.

The second upper limit value can be changed into any value according to actual needs. By setting the second upper limit value, waste of material due to excessive cutting is prevented. Further, after the shearing values of the head and the tail of the hot-rolled coil are calculated, the shearing values are automatically issued to a field control system according to the steel coil number identification through the calculation result, and the control system guides the PLC to complete the shearing operation of the head and the tail of the hot-rolled coil on the field. Wherein the shearing value comprises a shearing value for shearing the unqualified area of the hot rolled coil and a shearing value for shearing the defective part of the hot rolled coil.
Further, when shearing the hot rolled coil according to the defect shearing value, the shearing frequency limit can be set: when shearing is needed due to defects, the upper limit of shearing times is limited, several parts with the largest defects are selected as shearing objects, and several parts with relatively small defects can be cut without cutting, so that the waste of materials caused by excessive shearing is prevented.
According to some embodiments, a hot rolling table detector is used for data acquisition of a hot rolling roll thickness attribute, a hot rolling roll width attribute, a hot rolling roll crown attribute, a hot rolling roll asymmetric flatness attribute, a hot rolling roll wedge attribute and a hot rolling roll center line deviation attribute of each hot rolling roll in the production process of the hot rolling process, the attribute data and the defect data are detected by the hot rolling table detector, and the hot rolling table detector detects the defect data within the range of a preset threshold value according to the production stability requirement of the acid continuous rolling mill unit.
