CA1059347A Vertical edger for steel mill Google Patents
1. A modular edging mill assembly for use in removeable relation in a rolling mill, having housing means for placement in a mill pass-line; a horizontal input shaft for coupling to a horizontal drive shaft; a pair of housing head portions, each having an edging roll extending vertically therefrom; gear transmission means connecting said input shaft in driving A 200-mm-wide strip is cold rolled by a two-high mill in thickness from 2 to 1.5 mm, without any spread. The rolls are 300 mm in diameter and operate at 100 rpm. If the rolling load is 1.1 MN, determine the mill power required for this cold reduction, assuming typical value of lever arm ratio for cold rolling.Rolling SpringerLink

Basics of Rolling of Steel IspatGuru
Vertical rolls are used to control the width of the work simultaneously. Cluster mill or Sendzimir mill stand In this rolling mill stand, each of the work rolls is supported by two backing rolls. Cluster mill and Sendzimir mill are used for rolling thin strips of high strength materials and foils [0.0025 mm thick]. The work roll in theseVertical rolls are ordinarily not driven on a universal rolling mill. Therefore, when trying to apply strong pressure to the flange thickness to make H-shaped steel, etc., if the material comes into contact with the vertical roll first, it increases the possibility of faulty roll bites.Section Rolling Mill Steel Plantech

Vertical–horizontal coupling nonlinear vibration
Considering the dynamic influence of the roll vibration on the lubricant film thickness in the rolling deformation area, nonlinear dynamic rolling forces related to film thickness in the vertical and horizontal directions were obtained based on the Karman’s balance theory. Based on these dynamic rolling forces and the mechanical vibration of In [1], a mathematical model of the lateral plate motion in a roughing mill is proposed and used to analyze how the plate motion can be influenced by exerting lateral forces with edger rolls.It is further investigated how forces on the entry or exit side of the roll gap influence the stability of the plate motion. A review of models for the evolution of the Are edger rolls useful to control the plate motion and

Steel Billets, Bars, Rods Britannica
Steel Billets, Bars, Rods: Billets are the feedstock for long products of small cross section. In cases when they are not directly cast by a continuous caster, they are rolled from blooms by billet mills. One method of rolling billets, which are usually 75 to 125 millimetres square, is to use a three-high mill with box passes, as shown in A in the figure. After a rectangular Vertical roller mills offer supreme grinding with high energy-efficiency.
