Title:
METHOD FOR PRODUCING ROLLED SURFACE-TREATED STEEL SHEET, AND ROLLED SURFACE-TREATED STEEL SHEET
Document Type and Number:
WIPO Patent Application WO/2023/210822
Kind Code:
A1
Abstract:
[Problem] The present invention addresses the problem of: suppressing the occurrence of a crack even in a state where a rolled surface-treated steel sheet is stretched, while maintaining the hardness of the surface of the rolled surface-treated steel sheet; and improving the sheet passing properties during the time when the rolled surface-treated steel sheet is passed between drawing rolls or between sheet passing rolls. [Solution] The present invention provides a method for producing a rolled surface-treated steel sheet, the method comprising: an iron nickel alloy layer formation step in which an iron nickel alloy layer is formed on a steel sheet that serves as a base material; and a rolling step in which the steel sheet having the iron nickel alloy layer is rolled at a draft of 5% to 25% after the iron nickel alloy layer formation step.
