The HR coil, which is the basic raw material, is passed through the pickling line to remove the oxides or scales from strop surface to enable further reduction of thickness to desired level in cold rolling mills.This processing is required since rust in formed on the surface of the coils at room temperature whereas scales are formed at high temperature during rolling in hot strip mill.1. Ferric Oxide will form on the surface layer of the steel strip during the hot rolling, and the layer of Ferric Oxide is crisp and hard2. If it exits on the surface of the strip, it will decrease the surface quality of cold rolling strip3. Layer of Ferric Oxide must be removed before cold rolling4. Pickling processing is competent for the task5.
