METHOD OF ROLLING MILL ROLLS ADJUSTMENT AND ROLLING MILL Russian patent published in 2014 - IPC B21B37/60 

FIELD: process engineering.

SUBSTANCE: invention relates to adjustment of roll space between rolls 1, 2, 3, 4 of rolling mill 5 including at least two interacting working rolls 1, 2. Rolls wear and misalignment are compensated owing to that one of working rolls 1 can displace while bottom working roll 2 can revolve without displacement in rolling in direction perpendicular to rolling surface. To set rolling line P, fixed roll position is defined before rolling at two axial end points (S_act) with the help of appropriate instruments 8 arranged at two axial end points 13 of roll body or pad. Defined magnitude (S_act) is compared with rated value (S_rated). Height of working roll 2 is changed vertically by actuator 6 so that position (S) of fixed roll 2 reaches (S_rated) to make rolling line P. Proposed device comprises appropriate equipment.

EFFECT: higher accuracy of roll space adjustment.
