Abstract (en)
[origin: WO9502080A1] In a subsequent treatment process for pickled steel products which consists of rinsing the steel products with water in a flow rinsing installation, inert or noble gas is blown into at least one of the rinsing sections (1, 2, 3 or 4) of the rinsing installation. The formation of spots caused by hydrolysis on the surface of the steel products may thus be avoided in the event of a strip standstill. The device for carrying out the process consists of several rinsing sections (1, 2, 3, 4) provided each with at least one inlet (8) for a liquid rinsing medium. At least one of the rinsing sections (1, 2, 3 or 4) is provided with at least one inlet (19, 20) for blowing-in gases.
