  Analysis of roll stack deflection in a hot strip mill

  #0183;#32;Another roll deflection model based on the beam theory for the evaluation of the roll deflection in plate rolling was used by Ohe et al. (1994), where they assumed the pressure distribution between the rolled plate and the work roll as well as between the backup roll and the work roll to be a polynomial of fourth degree.

  should, when ordered from the mill, be noted no camber permitted. Otherwise, the mill may provide the members with a small amount of natural mill camber. g. Heat cambering should be performed only on lowcarbon steels. Application of heat to mediumand highcarbon steels increases the danger of embrittlement. ASTM A36, A572 Gr. 50,

  What is the Difference Between a 2 Hi Rolling Mill and a 4

  Different Properties of 2 Hi Rolling Mill and 4 Hi Rolling Mill . Many friends dont know what a 4 Hi Rolling Mill is. In fact, the 4 hi rolling mill is a combination of two working rolls and two supporting rolls. It is not only the drive mechanism for the backup roll, but also the work roll driven equipment.

  Design and function of CVC rolls as a flatness actuator in

  cold rolling mill is of the type where shifting of both first intermediate and inner second intermediate rolls are possible. The rolls are numbered and defined as: 1. Work roll, diameter between 5075 mm. 2. First intermediate roll (tapered), diameter between 90105 mm. 3. Inner second intermediate roll (CVC roll), diameter between 177182 mm. 4.

  Metal Rolling Manufacturing

  The camber that must be ground into a roll is very specific to a particular work width, material, and force load. A roll must usually be manufactured for only one metal rolling process. In some industrial metal rolling processes, rolls are given temporary camber by applying forces through their bearings.
