Abstract:
Pickling apparatus for pickling steel strip traveling substantially horizontally at high speed comprising a plurality of acid-containing sections in series for contacting said strip with acid, each of said acid-containing sections comprising an upstream end and a downstream end, said acid-containing sections comprising (a) means for maintaining a desired level of strip therein while permitting acid to contact both the top and bottom of said strip, (b) an exit for said strip in said downstream end including an arcuate deflector for acid flowing with said strip and on top thereof, said arcuate deflector being shaped so as to scoop at least a portion of said flowing acid and reverse its direction of flow at a level higher than that of said acid on said strip, and (c) an inclined separator panel for receiving acid from said arcuate deflector in said reverse direction of flow and guiding said acid to said upstream end of said section.
