Embodiment 1

[0035] like figure 1 As shown, a UCMW cold tandem cold mill textured roll rolling system includes a roll mode identification module, a basic setting calculation module, a textured roll constant rolling force setting module, a 5# frame reduction rate setting module, and rolling control system;

[0036] The roll mode identification module judges the roll mode;

[0037] The basic setting calculation module is connected with the roll mode identification module, selects the corresponding reduction rate constant table according to the textured roll mode judged by the roll mode identification module, obtains the required rolling parameters, and performs the setting calculation of the rolling model; The basic setting calculation module is connected with the rolling control system, and outputs the setting calculation results of the rolling model to the rolling control system;

[0038] The constant rolling force setting module of the textured roll is connected with the rolling control...

Embodiment 2

[0043] A method for rolling textured rolls of a UCMW cold tandem mill, which uses a roll mode identification module to identify the work roll mode of the 5# stand. Equip the 5# rack with textured rollers with roughness above 3.0μm (minimum roughness above 2.0μm). The basic setting calculation module obtains the required rolling parameters (used to calculate the maximum exit speed of the rolling mill, friction parameters, plate shape parameters, intermediate rolls and working roll bending and shifting amount, unit tension and initial unit tension at the taper), and then set and calculate the rolling model to determine rolling parameters such as load distribution, rolling speed, and roll gap (the specific calculation method above is It is well known in the art, and reference can be made to Chapter 5 Cold Rolling Process Control Model System of "Principles and Process Control of Strip Steel Continuous Rolling", edited by Wang Junsheng, Bai Jinlan, and Liu Xianghua, Science Press)...

Abstract

The invention relates to a texturing roll rolling system and method of a UCMW tandem cold rolling mill. The texturing roll rolling system and method of the UCMW tandem cold rolling mill comprises a rolling mode identity module, a basic setting and calculation module, a texturing roll constant-rolling-force setting module, a No.5 rack reduction ratio setting module and a rolling control system, wherein the rolling mode identity module is used for judging a roll mode; the basic setting and calculation module is used for obtaining required rolling parameters from a reduction ratio constant table corresponding to the texturing roll mode; the texturing roll constant-rolling-force setting module is used for calculating rolling force in the texturing roll mode according to the type, the width and thickness specifications and the rolling speed of strip steel; the No.5 rack reduction ratio setting module is used for selecting No.5 rack reduction ratio from the reduction ratio constant table corresponding to the texturing roll mode according to the type and the width and thickness specifications of a set steel coil. The invention additionally relates to a method using the system. The rolling system and the method provided by the invention have the advantages that the rolling mill can realize stable rolling in the texturing roll mode, the shape and dimension accuracy of finished strip steel plates can be guaranteed and especially the surface quality of the strip steel can be guaranteed.

Description

technical field [0001] The invention relates to the field of rolling process control of tandem cold rolling, in particular to a rolling system and method for textured rolls of UCMW tandem cold rolling mills. Background technique [0002] The UCMW pickling tandem mill is designed to produce medium and low-grade non-oriented silicon steel. Due to the technical requirements of the silicon steel plate, the rolls of the 5# stand are smooth rolls, and the process control model and parameter configuration use the smooth roll mode. In order to meet the market demand and plan to roll ordinary carbon steel with special requirements on the export surface, it is necessary to adjust the working roll of the 5# frame from the smooth roll to the textured roll. The surface roughness of the strip steel after cold rolling is formed by the transmission or copying of the surface microgeometric structure of the work roll of the 5# stand of the rolling mill, and the surface roughness is one of the...
