Before annealing, cold rolled strips surface must be cleaned to remove surface contamination. For this purpose, individual coils are welded into a continuous strip running through the cleaning process. First, the strip is brushed with sprayed hot alkaline solution and brushed in slots, and 80 percent of the lubrication residuals from the cold rolling process are removed. Then, the following electrolytic degreasing process makes the strip clean showing metal gloss. Finally, the strip is brushed again，rinsed, dried and dried into coils weighing about 15 metric tons.
