The push-pull hydrochloric acid shallow tank turbulent acid pickling process is used to remove the iron oxide layer on the surface of the hot rolled strip, and the irregular edge of the strip is cut off to provide qualified hot rolled sheet raw materials for the next process. The pickled strip is a pure iron surface that can be cold rolled or hot galvanized.
