Process for producing a sheet steel product coated with an anticorrosion system
摘要
The present invention relates to a process which makes it possible to economically produce highly corrosion-resistant and at the same time readily workable sheet steel products provided with an anticorrosion system. The process comprises the following steps: - preheating of the steel substrate to a strip temperature under a protective gas atmosphere; - cooling of the steel substrate to a strip entry temperature; - melt dip coating of the steel substrate in a zinc bath so that a metallic anticorrosion coating which in an intermediate layer has an Al content of not more than 0.5% by weight is formed on the steel substrate; - adjustment of the thickness of the metallic anticorrosion coating applied to the steel substrate in the melt bath to values of 3-20 μm on each side by stripping off excess coating material; - cooling of the steel substrate provided with the metallic anticorrosion coating and - application of the organic coating to the metallic anticorrosion coating of the steel substrate.
