ROLLING MILL WITH ROLL DEFLECTION ADJUSTED IN TWO PLANES Russian patent published in 2003 - IPC

FIELD: rolling processes and equipment, namely highly accurate rolling mills with rolls having automatic two-dimensional support for controlling their bending. SUBSTANCE: rolling mill includes housing, large number of rolls and roll chocks. Said roll chocks have mean chocks, terminal chocks capable for separating in horizontal direction and mean supporting unit arranged between said chocks. Rolling mill includes automatic two-dimensional mean supporting system having housing, chocks, first mean supporting unit arranged between them, second mean supporting unit arranged between housing and chocks, third mean supporting member arranged between housing and terminal chocks. Said mean supporting units have screw-down mechanism, horizontal supporting members, vertical supporting members and supporting members arranged between mean chocks and terminal chocks. EFFECT: improved design providing significantly reduced bending deformation of rolls, lowered fluctuations of size of rolled strips and thick sheets. 8 cl, 6 dwg
