COMPLEX METHOD OF MANAGEMENT AND CAGE TYPES FOR MILL TANDEM FOR COLD ROLLING Russian patent published in 2009 - IPC B21B13/14 

FIELD: metallurgy.

SUBSTANCE: method includes axial deflection at least working roll and mediate rollers, interacting with facilities of axial deflection. Ability of usage uniform units of rollers for application of different control systems by rolling is provided ensured by in one multistand tandem mill for cold rolling it is combined technology CVC/CVC^plus, PC- technology (Per-Cross), with rotation of each operating and intermediate roller parallel to strip plane and technology oriented on edge of displacement strip of operating or intermediate rollers, additionally each operating or intermediate roller allows symmetric body, increased per displacement value, with cylindrical or convex grinding, rollers relative to neutral position (S_ZW=0 or S_AW=0) of displacement in the middle of cage (Y-Y) are displaced symmetric to each other in opposite directions by its axis (X-X) of rotation per the same value.

EFFECT: enhancement at control of rolling process parametres in rolling mills of stand tandem of cool rolling, containing appropriately a couple of working rolls and backup roll in case of four-high rougher and additional couple of intermediate rollers in case of six-high cluster mill.
