The paper presents the design of the new lengthwise-wedge rolling mill providing regulation of a longitudinal and transversal thickness deviation and flatness, as well as reduction of rolling force from one stand to another in the direction of rolling. Deflection and elastic flattening of work stands in MSC.visualNastran 4D media are calculated. The results of calculation of rolling forces applied in diff erent directions in the 1st 2-hi stand are presented, as well as the results of calculation of distribution of elastic deformation of work rolls in the same stand via finite element method. It should be mentioned that distribution of summarized elastic metal movement in three directions correlates with deformed shape of rolls. In general, the value of elastic deformation of roll components is not large in the case of usage of back-up rolls, what testifies about rather high rigidity of roll block in the work stand. It is established that rolling in the new mill with decrease of rolling force results in diminishing of elastic roll deflection and transversal thickness deviation, as well as in improvement of flatness of rolled strips. The average value of transversal thickness deviation for cold-rolled strip makes 0.017 mm and measured flatness is inside the range 2.5–4.7 mm (with decrease of this value for more thick plates).
