MILL STAND FOR CALIBRATION OR REDUCING MILL WITH MULTIPLE POINTS OF PRESSURE APPLICATION Russian patent published in 2016 - IPC B21B27/02 

FIELD: metallurgy.

SUBSTANCE: invention relates to the field of rolling. Rolling stand for reducing tubes and round products comprises two or more rolls (10, 20, 30) defining the cross section of the rolling mill stand, the axis of which coincides with the axis Y of the rolling mill stand. Improved forms of products and decreasing the length of the rolling mill is provided by the fact that each roller has a respective rolling surface defining a straight line (B) of symmetry that runs along the rolling axis through the center of symmetry of the respective surface, thereby defining a first half and a second half of the corresponding surface two zones solution having a radial distance H2 from the axis of the rolling zone (1) a base gauge having radial distance H1 from the rolling axis at the intersection point of the corresponding surface with a corresponding straight line of symmetry, wherein in said corresponding rolling surface (S1, S2) Each roll is constructed with at least three zones of application of pressure. Rolling mill comprises a respective rolling stand.

EFFECT: improved forms of products and reducing the length of the rolling mill.
