Roll Camber Design for Cold Rolling Mills - ScienceDirect

01/09/1976  COMMENTS AND CONCLUSIONS A 4-high mill stand rolling a given order has a characteristic shape variation wi th strip width. The optimum roll camber, for a particular strip width, can be predicted using a shape analysis algorithm with a modified convergence equation. Drawing the optimum roll cambers for a range of strip widths on a common width axis enables a compromise ground camber

4 High Rolling Mill - Element

Rolling mill consisting of four rolls or known as a 4 High rolling mill is used for reducing material to extremely small thicknesses. Through the use of larger backup rolls, the issues of roll deflection can be avoided and smaller work rolls can be used. This reduction in work roll diameter: Reduces overall separating force required for reductions; Reduces overall energy

Roll Shape Design for Foil Rolling of a Four‐High Mill ...

27/01/2011  In this paper, a mathematical model for a four‐high mill is proposed to analyze the elastic deformation of its back‐up and work rolls, including their respective axial deflections and surface flatness. The contact pressure between the back‐up and work rolls and that between the work roll and foil are functions of the roll’s position in the axial direction.

Rolling of hot strip and strip defects – IspatGuru

14/01/2017  Mill spring causes the thickness of the strip exiting from the rolling mill to be greater than the roll gap set under no-load conditions. Precise thickness rolling requires the elastic constant of the mill. Calibration curves are needed. The elastic constants are usually in the range of 1 GNm-1 to 3 GNm-1 for screw-loaded rolling mills and around 4 GNm-1 for hydraulically loaded mills.

AISTECH 2019 Primetals Technologies

08/05/2019  In order to meet these trends, new mill stand technology allows producers to adapt the last finishing mill stand by efficiently switching from a 4-high mode to a 6-high mode with small work roll diameter based on production needs. A smaller work roll diameter allows for higher reductions, resulting in thinner hot-strip gauges with metallurgical benefits.

Hot Cold Working and the Rolling Process

Another method to reduce or eliminate elastic roll deflection is to use materials of high elastic modulus, such as sintered carbide, for the work rolls. A more common method to counter the effects of roll bending is the usage of cambered rolls. The degree of cambering depends on the width of the metal piece, flow stress of the material and the reduction per pass. However
