Document Type and Number:
WIPO Patent Application WO/2023/286441
Kind Code:
A1
Abstract:
To provide a steel sheet dehydrogenation device, a system for manufacturing a steel sheet, and a method for manufacturing a steel sheet, whereby it is possible to manufacture a steel sheet having exceptional hydrogen embrittlement resistance characteristics without changing the mechanical characteristics of the steel sheet. Provided is a dehydrogenation device having an accommodation unit for accommodating a steel sheet coil obtained by winding a steel strip into a coil, and a vibration-applying device for applying vibration to the steel sheet coil accommodated in the accommodation unit so that the frequency of vibration of the steel sheet coil is 100-100,000 Hz and the maximum amplitude of the steel sheet coil ranges from 10 nm to 500 μm.
