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

Jan 27, · 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. In this analytical model, the

EP0728539A1 - Method of and apparatus for removing camber

The invention relates to a method of and apparatus for removing excess longitudinal camber from MULT (multiple) strips (14, 18) cut from a rolled thin gauge steel sheet (12). Each cambered MULT strip is passed through a rolling mill (30) having rolls (32, 34) with strip-contacting surfaces (35, 33) which are vertically adjustable. One roll (32) is inclined relative to the other roll (34) so as

Sheet Camber and Cambering of Rolls | Metallurgy

The middle of roll becomes hotter than its ends and hence roll diameter in the middle of roll increases. In hot rolling mills this effect is quite pronounced and should be taken into account while calculating the roll camber. In cold rolling mills the coolant supply at different points on roll surface may be adjusted to minimize this effect.
