Abstract

A method for designing width of rough rolling strip steel includes applying short time mode of fine rolling natural broad-siding to calculate out natural broad-siding of fine rolling then confirming natural broad-siding allowance according to heat rolling width and prediction accuracy of fine rolling natural broad-siding, finally confirming design value of rough rolling width of current strip steel according to width allowance and natural broad-siding of fine rolling.

Description

technical field

[0001] The invention relates to forming processing of hot-rolled strip steel, in particular to a method for optimally setting the width of rough-rolled strip steel during the width control process of hot-rolled strip steel. Background technique

[0002] Width is an important technical index of hot-rolled products. The width requirement of hot-rolled products does not have a negative tolerance. Once the actual width of the product is smaller than the required width of the finished product, the product will be rejected.

[0003] The general hot rolling production process includes rough rolling and finish rolling two process sections. The rough rolling process section has vertical roll reduction equipment, that is, it has the control function of width reduction, so the strip width control function is mainly in rough rolling. However, after the strip steel leaves the roughing mill and enters the finishing mill, the width of the strip steel in the finishing rollin...

Embodiment Construction

[0103] In order to understand the content of the present invention more clearly, the following will be further described in detail in conjunction with the accompanying drawings and specific embodiments:

[0104] Please refer to Figure 1 to start rough rolling width setting, first read the target width, target thickness, and target reduction of the strip to be rolled from the layer data table, and read the previously rolled strip the actual natural width of the strip; read the specification data and model adaptive data of the current strip; calculate the natural width of the current strip; Statistical accuracy of width control of standard strip steel, calculated according to the statistical accuracy to calculate the additional margin of the strip width; according to the calculated natural width of the finishing rolling, the additional margin of the current strip width, the target width of finishing rolling and manual correction by the operator value, determine the rough rolling...
