MUMBAI, India, Sept. 26 -- Intellectual Property India has published a patent application (202517081175 A) filed by Jfe Steel Corporation, Tokyo, on Aug. 27, for 'method for predicting cross-sectional dimension of shape steel, method for manufacturing shape steel, cross-sectional dimension prediction device for shape steel, and method for generating cross-sectional dimension prediction model.'
Inventor(s) include Yamaguchi Hideto; Goto Hiroto; Maeno Hayato; Katayama Takashi; and Baba Masaaki.
The application for the patent was published on Sept. 26, under issue no. 39/2025.
According to the abstract released by the Intellectual Property India: "Provided is a method for predicting a cross-sectional dimension of a shape steel, the method being applicable to shape steels having various cross-sectional dimensions without being limited to a preceding rolled material and succeeding rolled material continuously hot-rolled, as long as the shape steel is manufactured by hot-rolling with the same roll set. Provided is a cross-sectional dimension prediction method of a shape steel for predicting a cross-sectional dimension for a shape steel manufactured by hot-rolling, wherein the method involves: outputting the difference between cross-sectional dimension deviations by inputting, to a cross-sectional dimension prediction model which uses, as an input, the difference between rolling operation parameters of two shape steels manufactured by hot-rolling with the same roll set and uses, as an output, the difference between cross-sectional dimension deviations of the two shape steels, the difference between rolling operation parameters of a shape steel to be a preceding material manufactured by hot-rolling with the roll set and rolling operation parameters of a shape steel to be manufactured by hot-rolling with the roll set, the cross-sectional dimension deviations being deviations between target dimensions and actual dimensions of the shape steels; and using the output difference between the cross-sectional dimension deviations and the cross-sectional dimension of the shape steel to be the preceding material to predict the cross-sectional dimension of a shape steel to be manufactured."
The patent application was internationally filed on Mar. 05, 2024, under International application No.PCT/JP2024/008236.
