ALUMINUM-SILICON-PLATED STEEL PLATE AND THERMOFORMED COMPONENT, AND MANUFACTURING METHODS THEREFOR

Document Type and Number:

WIPO Patent Application WO/2024/017394

Kind Code:

A1

Abstract:

An aluminum-silicon-plated steel plate with a coating, the aluminum-silicon-plated steel plate comprising a steel substrate and an aluminum-silicon plating plated on the surface of the steel substrate, the surface of the aluminum-silicon plating being further coated with a coating, wherein the coating contains C, H, O, N and Si and does not contain P, and the content of Si in the coating is 10-1000 mg/m2. A manufacturing method for the aluminum-silicon-plated steel plate, and a thermoformed component prepared by using the aluminum-silicon-plated steel plate. The manufacturing method for the aluminum-silicon-plated steel plate comprises the steps of steel making, hot rolling, cold rolling, hot dipping, leveling and coating with a paint to form a coating. A manufacturing method for the thermoformed component specifically comprises the steps of: (1) cutting an aluminum-silicon-plated steel plate into a blank; (2) subjecting same to a heat treatment in a furnace, wherein the heating rate of the blank from room temperature to 700ºC is controlled to be 5-30ºC/s, and the heating rate at 700ºC or higher is controlled to be 1-10ºC/s; and (3) transferring the blank into a mold for hot stamping or rolling forming.
