Problems solved by technology

For varying strip width tolerances, constant model control width deviation limits improvement in strip width control accuracy
Even if the operator can intervene in the width compensation value on the HMI screen, the problem cannot be solved scientifically due to the joint influence of various factors such as the width tolerance change and the inconsistency in setting the width compensation value of the operators in each team.

Embodiment 1

[0049] Get PDI width tolerance 0~10mm,

[0050] The width tolerance factor is formed by the PDI width tolerance, the middle value of the width tolerance factor=PDI width tolerance zone=(PDI width tolerance upper limit+PDI width tolerance lower limit)÷2=(0+10)÷2=5mm ,

[0051] The width tolerance factor combined with the width compensation value forms a model control width deviation, and the model control width deviation=5mm+width compensation value.

Embodiment 2

[0053] Get PDI width tolerance 0~15mm,

[0054] The width tolerance factor is formed by the PDI width tolerance, the middle value of the width tolerance factor=PDI width tolerance zone=(PDI width tolerance upper limit value+PDI width tolerance lower limit value)÷2=(0+15)÷2=7.5 mm,

[0055] The width tolerance factor combined with the width compensation value forms a model control width deviation, and the model control width deviation=7.5mm+width compensation value.

Embodiment 3

[0057] Get PDI width tolerance 0~20mm,

[0058] The width tolerance factor is formed by the PDI width tolerance, the middle value of the width tolerance factor=PDI width tolerance zone=(PDI width tolerance upper limit+PDI width tolerance lower limit value)÷2=(0+20)÷2=10mm ,

[0059] The width tolerance factor combined with the width compensation value forms a model control width deviation, and the model control width deviation=10mm+width compensation value.

Abstract

The invention provides a method for improving the strip steel width control precision and relates to a method applicable to control of the steel strip width. In order to overcome defects in the prior art, the method for improving the strip steel width control precision is provided. The method for improving the strip steel width control precision comprises the following steps: a PDI width tolerance is acquired; a width tolerance factor is formed through the PDI width tolerance; and the width tolerance factor and a width compensation value are combined to form a model control width deviation.

Description

technical field [0001] The invention relates to the technical field of hot rolling, in particular to a method suitable for controlling the width of strip steel. Background technique [0002] In order to meet the customer's requirements for the use of strip width, the width of hot-rolled strip steel is controlled by positive tolerances, for example: [0-15], [0-20], [0-25], etc. are relatively common width tolerances. [0003] The control target width of the rough rolling model of the hot rolling production line is based on the PDI target width, plus the constant width offset solidified in the model, plus the width compensation value intervened by the operator on the HMI. which is: [0004] Model control target width = PDI target width + width offset + width compensation value (1) [0005] And the model control width deviation can use the model control target width, minus the PDI target width. which is: [0006] Model Control Width Deviation = Model Control Target Width - ...
