Embodiment Construction

[0034] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0035] The present embodiment provides a rolling method of an extremely thin gauge steel strip, such as figure 1 As shown, the methods include:

[0036] S110, obtaining the initial thickness of the steel strip;

[0037] In order to better understand the technical solution of this embodiment, the rolling process of the strip is firstly introduced. The initial raw materials are independent. In order to be able to roll continuously,...

Abstract

The invention provides a rolling method, device, medium and equipment for ultra-thin strip steel, and the method comprises the steps that if it is determined that the initial thickness of the strip steel is smaller than 0.2 mm, the target thickness of the strip steel at an outlet of a fifth rack is adjusted according to a thickness adjusting strategy, and the target thickness is larger than the preset thickness of the strip steel at the outlet of the fifth rack before adjustment; correspondingly adjusting the thickness of the strip steel at the outlets of the first rack, the second rack, the third rack and the fourth rack according to the target thickness; the roll bending force compensation value of the middle roll and the working roll of the fifth rack is controlled to be zero; in this way, when extremely thin strip steel is rolled, the thickness of the strip steel at the outlet of the fifth rack is increased based on the initial thickness of the strip steel, and accumulation at the flying shear due to strip head thinning is avoided; and the compensation value of the roll bending force of the middle roll and the working roll of the fifth rack is zero, so that the roll bending force is prevented from being suddenly changed during shearing, the stability of the strip shape is ensured, and the strip head can be ensured to smoothly run into the belt wrapper for smooth threading.

Description

technical field [0001] The invention belongs to the technical field of strip steel rolling, and in particular relates to a rolling method, device, medium and equipment of ultra-thin specification strip steel. Background technique [0002] Jingtang 1420 five-stand tandem rolling unit has great difficulty in rolling extremely thin specification materials from shear threading to speed-up rolling, especially when the material thickness is less than 0.17mm, the shearing and stable threading has always been a very difficult problem. Major difficulties, such as: after cutting, the tape ends accumulate on the flying shears and pinch rollers, making it impossible to thread the tape, which affects the efficiency of the production line. Contents of the invention [0003] Aiming at the problems existing in the prior art, the embodiment of the present invention provides a rolling method, device, medium and equipment of an ultra-thin gauge steel strip, which is used to solve the problem...
