Abstract
This disclosure relates to a method of producing a hot-dip-coated steel sheet and to a hot-dip-coated steel sheet.
Claims14
A method of producing a hot-dip-coated steel sheet, the method comprising:
- providing a cold-rolled steel substrate, having a deterministic surface structure on one or both sides;
- subsequent to the providing, coating on the cold-rolled steel substrate having a deterministic surface structure on one or both sides with a zinc-based coating by hot dip coating, in order to obtain the hot-dip-coated steel sheet, wherein the deterministic surface structure is applied to the steel substrate prior to the hot dip coating to influence a crystallization nuclei density of the zinc-based coating during solidification;
- and
- subjecting the hot-dip-coated steel sheet to skin pass rolling.
