Abstract
A method and setup for pickling strip material which is oriented in a widthwise upright position. The method includes spraying rinse water onto the material, gauging the thickness of the material, then alternately spraying pickling acid onto the material and wiping that acid off of the material a plurality of times, then rinsing the material soon after the last acid spraying step to remove acid and drying the material. The setup and method can be used to pickle either material having an undetermined length, or strips of prescribed lengths.
