Abstract

The invention relates to a method and a device for reducing the formation of scales on rolling stock (3) which leaves the roll stand. According to the invention, heated water, especially wet steam, is sprayed onto the rolling stock (3) when it leaves the roll stand. Said heated water, especially the wet steam, is sprayed onto the rolling stock (3) from a main direction component of spraying which is not perpendicular to the surface of the rolling stock (3).
