Roll support device for correcting the cross section of a strip due to elastic deformation of a multi-roll mill for strip material

摘要

The invention relates to a roll support device for correcting the cross-section of a strip due to elastic deformation of a multi-roll mill for strip material, having at least one set of support rollers (1 - 5) assigned to each working roll (W1, W2), which support rollers are distributed over the entire axial length of the working roll (W1) and are mounted so as to be rotatable on a carrying axle (16) which is held in the roll housing (17) of the roll mill and supported on support saddles (18 - 23) arranged between the support rollers (1 - 5) and carried by roll housings (17, 47), at least the support rollers (2 - 4) arranged between the terminal support rollers (1, 5) being adjustable by means of eccentric rings (12 - 14) to different degrees of eccentricity, the carrying axle (16, 46) being held so as to be rotationally adjustable in the roll housing (17) and the eccentric rings (12 - 14) for the individual support rollers (2 - 4) being arranged so as to be rotationally fixed on the carrying axle (16, 46), with an eccentricity of varying effectiveness on rotation of the carrying axle (16). To correct, in operation, the deflection of the working roll (W1) at low adjusting forces, eccentric rings (12 - 14) are arranged between the carrying axle (16) and the support rollers (2 - 4). IMAGE
