Abstract

PURPOSE:To surely and efficiently prevent the yellowing of a steel strip after passing through a pickling tank in a pickling line, by coating the surfaces of the steel strip with a yellowing preventing soln. on the outlet side of the picking tank while the strip is travelled at a low speed. CONSTITUTION:When a steel strip 6 is pickled in a pickling tank 1, washed with water sprayed from sprayers 2 and further washed by immersion in warm water in an immersion tank 3, the surfaces of the strip 6 are coated with a yellowing preventing soln. by means of a coating device 5 on the outlet side of the pickling tank 1 while the strip 6 is travelled at a low speed between the tanks 1, 3. The yellowing preventing soln. contains a chelating agent as an essential component.
