摘要

A method of predicting roundness of steel pipes according to the present invention isOne or more parameters selected from the attribute information of the steel plateOne or more parameters selected from the operating parameters of the press bend processOne or more parameters selected from the operational parameters of the seam gap reduction process are included as input data.The roundness information of steel pipe after expansion process is output data.Using a roundness prediction model learned by machine learningIt includes the step of predicting the roundness of steel pipes after the expansion process.
