Date Jan. 19, 1995In a process for post-treatment of pickled steel products by rinsing with water in continuous rinsing plants, inert gas or rare gas is blown into at least one of the rinsing sections (1,2,3 or 4) of the rinsing plant. This prevents the formation of hydrolysis stains on the surface of the steel products in case of the strip standing still. The device for carrying out the process consists of several rinsing sectors 1, 2, 3, 4, with at least one feed opening 8 for liquid medium, with at least one of the rinsing sections 1,2,3 or 4 being provided with at least one feed opening 19, 20 for blowing in gases.
