Abstract
During the cold rolling process of austenitic stainless steel, the product usually presents some level of transverse bending or crossbow. The flat shape is normally obtained in the final annealing process, and when required, in equipment such as temper mill or flattening leveler. However, crossbow during the annealing process is critical, specially to the product surface quality and process safety. Thus, during the cold rolling, the mechanism that causes crossbow needs to be better understood and controlled. At this work, a statistical study is performed with data of the cold rolling process, aiming to correlate the variables of the process with the crossbow obtained in manufactured coils of austenitic steels produced in Sendzimir mills at Aperam South America. The results showed no correlation of the investigated variables and the strip crossbow.
