Title:
HOT-ROLLED H-SHAPED STEEL AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/262580
Kind Code:
A1
Abstract:
Disclosed in the present invention is hot-rolled H-shaped steel, which comprises a web plate, a first flange plate and a second flange plate, wherein a thickness difference |T1-T2| between the first flange plate and the second flange plate is greater than 0, the ratio of an area difference |S1-S2| between the first flange plate and the second flange plate to an area S1 of the first flange plate is not greater than 1, or the ratio of the area difference |S1-S2| between the first flange plate and the second flange plate to an area S2 of the second flange plate is not greater than 1. The hot-rolled H-shaped steel of the present invention can satisfy the production requirements of different thicknesses of flanges of various specifications on two sides, and can also prevent lateral bending in a rolling process, and the difference of metal flow per second of the flanges on two sides in the rolling process is controlled within a certain range, such that the hot-rolled H-shaped steel with different thicknesses of flanges on two sides is stably produced. Further disclosed in the present invention is a production method for the hot-rolled H-shaped steel.
