Abstract：The pickling effect of the hot rolled strip in the rolling process of Ti-IF steel ferrite region was preliminarily studied and analyzed. By comparing the macroscopic morphology of the IF steel in the case of the different picking time, the pickling kinetic curves under the different processes were obtained. According to the XRD results, it can be concluded that the composition of the oxide scale under the ferrite rolling process condition was the same as that under the conventional process condition. Through the experimental analysis, it can be shown that comparing the ferrite rolling process with the conventional rolling process, the pickling time of the surface scale was reduced by about 30%, which greatly improved the pickling efficiency, and laid the foundation for improving the production efficiency and reducing the production cost for the next working procedure.
