  • Process for Producing a Sheet Steel Product Coated with an Anticorrosion System
    Publication number: 20100055344
    Abstract: Economic production of highly corrosion-resistant flat steel products with a corrosion protection system, which are at the same time easy to process further, is described. The following work steps are applied: preheating the steel substrate to a strip temperature under inert gas atmosphere; cooling the steel substrate to the strip inlet temperature; hot dip coating of the steel substrate in a zinc bath so that a metallic corrosion protection coating is formed on the steel substrate which has an Al content of max 0.5 wt. % in an intermediate layer; adjusting the thickness of the metallic corrosion protection coating applied to the steel substrate in the melt bath to values of 3 to 20 ?m per side by scraping away excess coating material; cooling the steel substrate with the metallic corrosion protection coating; and applying the organic coating to the metallic corrosion protection coating of the steel substrate.
