Abstract: A flat steel product for production of a sheet metal component by hot forming includes a steel substrate consisting of a steel including 0.1-3% by weight of Mn and optionally up to 0.01% by weight of B, an aluminium-based coating disposed on at least one side of the steel substrate. A coating here has an applied layer weight of 15-30 g/m2. In addition, the coating has an Al base layer consisting of 1.0-15% by weight of Si, optionally 2-4% by weight of Fe, 0.1-5.0% by weight of alkali metals or alkaline earth metals, and optional further constituents, the contents of which are limited to a total of not more than 2.0% by weight, and aluminium as the balance.

Abstract: The invention relates to a device and a method for hot-dip coating a metal strip with a metal covering, wherein the metal strip is directed continuously through a melt bath, wherein the thickness of the metal covering present on the metal strip when it leaves the melt bath is adjusted by means of a scraping device, and wherein slag which is present on the melt bath is driven away from the metal strip leaving the melt bath by means of a gas flow. To prevent slag from coming into contact with the metal strip leaving the melt bath, the invention drives away the slag from the metal strip by means of at least one nozzle which is arranged in close proximity to the metal strip, that a gas flow which extends over the width of the metal strip is directed onto the surface of the melt bath.
