Title:
SHAPE CONTROL METHOD, COMPUTATION DEVICE, INFORMATION PROCESSING PROGRAM, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/102791
Kind Code:
A1
Abstract:
Through the present invention, shape control for a rolled material, for endowing a rolled material with a good rolling shape, is realized using a numerical expression determined on the basis of a highly versatile mathematical model that can be used in common without regard to variation in the type and structure of a shape control mechanism of a multistage rolling mill. The shape control method according to the present invention includes a numerical expression determination step for determining a numerical expression on the basis of a mathematical model, and a control step for controlling the rolling shape of a rolled material using the numerical expression, a controlled variable influence term for the shape control mechanism in the mathematical model being expressed as being multiplied by a power function having the controlled variable for the shape control mechanism as the base thereof.
