20 high mill intermediate roller cone

Abstract

The invention relates to a middle roller cone of a twenty high rolling mill. The cone is a cone of multi-stage conicity and a double-stage conicity or third-stage conicity. The cone part of one middle roller of a twenty high rolling mill is improved by the invention, namely, the originally universal single conicity is improved into the double-stage conicity or the third-stage conicity; as the situation that part of a roller system is stressed too much is improved, the situation of uneven deformation of the corresponding position of a foil is lightened; a double-rib wave detect is eliminated; and the quality of the plate shape is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of rolling mills, in particular to a cone of a twenty-high rolling mill-intermediate roll. Background technique [0002] The thinner the rolled strip, the more pronounced its susceptibility to uneven deformation, so the shape is more difficult to control. For 20-high mills, the flatness defects that are prone to occur are edge waves and second rib waves, which are the most common defects in the shape control of almost all 20-high rolling mills. The 20-high reversing cold rolling mill in Sendzimir, USA has the hydraulic adjustment of the back-up roll profile and the axial twitch adjustment means of an intermediate roll with a taper in terms of strip shape control. The side wave has obvious effect, but the improvement effect on the second rib wave is not significant. Twenty-high rolling mills have always lacked effective means to control the second rib wave. The thinner the thickness of the strip, the more o...

Problems solved by technology

The 20-high reversing cold rolling mill in Sendzimir, USA has the hydraulic adjustment of the back-up roll profile and the axial twitch adjustment means of an intermediate roll with a taper in terms of strip shape control. There is a significant effect on side waves, but the improvement effect on second-rib waves is not significant

Twenty-high rolling mills have always lacked effective means to control the second rib wave. The thinner the thickness of the strip, the more obvious the second rib wave defect, such as figure 1 shown
