METHOD FOR GENERATING MODEL FOR PREDICTING OVALITY OF STEEL PIPE, METHOD FOR PREDICTING OVALITY OF STEEL PIPE, METHOD FOR CONTROLLING OVALITY OF STEEL PIPE AND DEVICE FOR PREDICTING OVALITY OF STEEL PIPE Russian patent published in 2024 - IPC B21D5/01 B21C37/08 G05B13/04 

FIELD: metal forming.

SUBSTANCE: invention can be used in production of steel pipes by bending. Steel pipe ovality prediction model is generated by performing a numerical calculation in which the input data is a set of operating conditions data, and the output data is the steel pipe ovality after expansion. Set of operating conditions is repeatedly changed and a plurality of pairs is generated from data of the set of operating conditions and data on ovality of the steel pipe after expansion, corresponding to the set of operating conditions, as training data. Ovality prediction model is generated, for which the input data is a set of operating conditions data, and the output data is the steel pipe ovality after expansion. Ovality prediction model is generated in autonomous mode by machine learning.

EFFECT: obtaining pipes with required ovality.
