Abstract

The invention discloses a characteristic parameter identification method of the lateral distribution of strip steel thickness on the basis of a mechanism, and relates to the field of strip steel quality control. In the method, one function is adopted to describe the lateral distribution of the strip steel thickness in the whole width direction of the strip steel, the function consists of a basic mode based on an elastic flattening mechanism and a common polynomial, so that the function has few parameters and high precision, and strip steel edge drop can be favorably fitted. The characteristic parameter identification method has an important meaning on the aspects of identifying the section shape of strip materials, lowering influence on the plate shape of a finished product by the shape fluctuation of a material feeding section and improving the quality of the strip steel.

Description

technical field

[0001] The invention relates to a method for identifying characteristic parameters of the lateral distribution of strip steel thickness, in particular to a mechanism-based identification method for characteristic parameters of the lateral distribution of strip steel thickness, and belongs to the technical field of controlling the quality of strip steel by means of computers. Background technique

[0002] Steel rolling production is the post process of steel production, and strip rolling is a part of steel rolling production. With the development of industries such as automobile manufacturing, higher requirements are put forward for the dimensional accuracy and shape of strip steel.

[0003] In the strip rolling production process, there will be local thinning phenomenon at the edge. There are many reasons for this phenomenon, including: in the width direction of the strip, the rolling pressure is unevenly distributed, and the rolling force at the edge will be...
