Problems solved by technology

[0007] (1) The surface of the strip coiled by the traditional coiler is prone to creases, which affects the subsequent polishing, electroplating and other processes of the product
[0008] (2) Generally, the folded part is directly subtracted and scrapped, which will cause direct economic losses

Embodiment 1

[0110] The big data-based steel coil slitting and printing management method provided by the embodiment of the present invention includes image 3 Included content, the difference is that the roll diameter calculation method further includes:

[0111] Rolling diameter calculation method 1:

[0112] Rolling diameter calculation method two:

[0113] Among them, L is the coiled length, H is the thickness of the steel coil, r is the inner diameter of the coil, v is the line speed of the unit, i is the speed ratio, and n is the rotational speed.

Embodiment 2

[0115] The big data-based steel coil slitting and printing management method provided by the embodiment of the present invention includes image 3 The content included, the difference is that the abnormal conditions in the judgment of system abnormal conditions through the fault judgment program include:

[0116] (1) Turn on the auxiliary winding roller of the coiler, so that the drum of the coiler rotates at a speed of 2m / s. Normally, a continuous buzzing sound below 30 decibels should be heard. If you can hear three periodic clicking, clicking, and clicking sounds greater than 90 decibels every time the reel rotates, it can be preliminarily determined that the accuracy of the reel of the coiler is abnormal.

[0117] (2) Observing on the man-machine interface monitoring screen of the coiler operation table, if the pressure of the coiler auxiliary roller of the coiler reaches more than 30KN during zero adjustment, and at the same time, the coiler auxiliary roller of the zero a...

Embodiment 3

[0120] The big data-based steel coil slitting and printing management method provided by the embodiment of the present invention includes image 3 The content included, the difference is that the abnormal situation in the judgment of the abnormal situation of the system through the fault judgment program further includes:

[0121] (1) During the zero-adjustment process, listen to the sound of the contact between the coiler auxiliary roller and the reel on the spot, and observe the zero-adjustment on the man-machine interface monitoring screen of the coiler operation desk. Two to three sounds, it can be considered that the zero adjustment is abnormal, and it can be further judged that the coil accuracy of the coiler is abnormal.

[0122] (2) After the zero adjustment is completed, the auxiliary roll of the coiler is opened quickly, and the reel runs at a speed of 2M / S. Adjust the roll gap of the auxiliary roll of the programmable automation controller to -1mm. If the sound bel...

Abstract

The invention belongs to the technical field of steel coil longitudinal shear printing, and discloses a steel coil longitudinal shear printing management system and method based on big data. The steelcoil longitudinal shear printing management system comprises a coil diameter monitoring module, a steel coil cutting module, a central control module, a steel coil crimping module, a continuous rolling module, an angle adjusting module, an expansion supporting module, a pressure sensing module, a communication module, an anti-skid module, a fault judgment module, an early warning module, an emergency braking module, a data storage module, a terminal module, a power supply module, an illumination module and a display module. According to the steel coil longitudinal shear printing management system, a coil diameter error monitoring module and an automatic adjusting sub-module are arranged in a rolling unit, the problem that the tension error between the two rolling machines is large so thatthe two rolling machines cannot normally run is avoided. According to the steel coil longitudinal shear printing management system, the scrap steel accident caused by the motor fault is automaticallyjudged, the scrap steel is guaranteed to be uniformly accumulated on a roller way, the scrap steel is prevented from tipping or twisting, and a good condition is created for subsequent scrap steel treatment.

Description

technical field [0001] The invention belongs to the technical field of steel coil slitting and printing, and in particular relates to a management system and method for steel coil slitting and printing based on big data. Background technique [0002] Currently, the closest prior art: [0003] Strip coiler is an important metallurgical equipment to realize continuous, mechanized and automated strip production. Coilers are widely used in production lines such as annealing, pickling, smoothing, coiling, recoiling, welding, shearing, coating and finishing. Due to the different process requirements and installation requirements of various units, the coiler The structures are also different. [0004] Due to the ejection of force between the expansion sheet of the uncoiler and the raw material / finished product, there are folds similar to half-folded horizontally or vertically on the surface of the material, some of which are clearly visible, and there are folds similar to half-fo...
