Embodiment Construction

[0080] A flatness evaluation system based on the strip transverse flatness distribution proposed by the present invention can carry out flatness evaluation in different areas along the strip width direction, effectively solving the inability of the conventional strip flatness evaluation results based on the strip transverse mean property. The problem of effectively reflecting the actual flatness defects and distribution of strip steel is applied to the cold rolling flatness control system. The detailed description is as follows in conjunction with the drawings and examples:

[0081] Taking a concrete tandem cold rolling production line as an example, the whole process of applying the flatness evaluation system based on the strip transverse flatness distribution to it will be described in detail below.

[0082] The main parameters of the cold tandem rolling line selected in this example are:

[0083] Continuous rolling process section: SMS five-stand tandem cold rolling unit; ...

Abstract

The invention discloses a flatness evaluation system and a flatness evaluation method based on transverse flatness distribution of band steel, and belongs to the technical field of automatic control over cold-rolling flatness. The band steel is divided into an operation side edge region, a transmission side edge region, a 1 / 4 operation side region, a 1 / 4 transmission side region and a middle band steel region along the transverse (width) direction of the band steel, so that evaluation of the flatness on the operation side, evaluation of the flatness of the transmission side, evaluation of the flatness at the 1 / 4 position on the operation side, evaluation of the flatness at the 1 / 4 position on the transmission side and evaluation of the flatness in the middle of the band steel can be correspondingly calculated respectively. According to the flatness evaluation system and the flatness evaluation method, the problems of defective and distribution conditions of actual flatness of the band steel cannot be effectively reflected according to a conventional band steel flatness evaluation result based on the transverse mean value property of the band steel can be solved; an accurate control basis is provided for control over the flatness of the band steel; therefore, the flatness qualification rate and the yield of cold-rolled band steel are improved.

Description

technical field [0001] The invention belongs to the technical field of automatic control of cold rolling flatness, in particular to a flatness evaluation system based on the horizontal flatness distribution of strip steel. Background technique [0002] The flatness quality of cold-rolled strip steel is one of the most important quality indicators pursued by cold-rolled production, so the cold-rolled flatness control system is a key system in the cold-rolled production process. There are many factors affecting the efficient operation of the cold-rolled strip flatness control system, among which the flatness evaluation of the cold-rolled strip is the key factor of the flatness control system, which determines the control target of the cold-rolled strip flatness control system, and further determines the What kind of control means should be adopted by the cold rolling flatness control system, and how much control should be used to solve the flatness defects reflected in the col...
