The development of working patterns of rolling is very important to create and update a technology of producing steel strips. In addition, it used in estimation of a possibility of equipment for producing new dimensions of steel strip. We used the invariable method to design the pattern of rolling, which based on automatic computerassistant engineering. With help of this method, for example, we have calculated rational total strain amount and rolling speed with maximum productivity for different kinds of steel grades on PLTCM 2000 (Picking Line Tandem Cold Mill). CR CAD software adjustment for the specification of PLTCM 2000 unit provided suitable matching of assessed speed modes at the combined unit with actual data as well as reduced errors of calculation of rolling effort to 0.78 MN. With adjusted software variants of PLCTM 2000, modes of rolling bands of various dimensional and grade gauge, as well as rational combinations of overall reduction and rolling speed of steel grades belonging to various strength groups at TCM 2000 mill stand were established.
