The longitudinal wedge mill (LWM) of a new design is proposed in this article. By using the MSC.SuperForge software product which designed for the stress-strained state of the billet when rolling strips from steel S235JR on the LWM. The STD 812 plastometer analyzed the influence of temperature-deformation processing modes on the microstructure of S235JR steel which rolled on LWM, the conditions for the formation of a fine-grained structure were noted. The rational modes of hot and cold rolling and their effect on the anisotropy of sheet metals from steel S235JR have been defined. It was proved in our work that compared with cold rolling, during hot rolling of sheet billets in the sheet plane it does not appear the significant anisotropy of mechanical properties
