Backup Roll. The back up roll is a roll that supports the work roll and is the largest and heaviest roll used in rolling mills.The roll can support intermediate roll for the purpose of avoiding deflection of the work roll and affect on the yield and quality of the plate and strip rolling mill.The quality characteristics of the backup roll are high surface hardness, good hardness uniformity …

A coupled vibration model of hot rolling mill rolls under multiple nonlinear effects is established by considering the nonlinear spring force produced by the hydraulic cylinder, the nonlinear friction between the work rolls, the dynamic variation of rolling force, and the effect of external excitation as well as according to the structural constraints of a four-high hot rolling mill in the ...
The vibration model of mill rolls is shown in Fig. 2. Where m 1 is the equivalent mass of backup roll and work roll, c 1 is the equivalent damping of rolled piece, k 1 is the equivalent stiffness of the rolled piece, F l = F c o s ω t is equivalent load force, F is external excitation amplitude, ω is the angular frequency of external excitation.

Backup roll contour of a SmartCrown tandem cold rolling mill. 01/06/2008 For the SmartCrown tandem cold mill, two aspects of work have been done: one is proposing the Smart-Crown plus work roll contour based on the optimization of the SmartCrown and the other is developing the new backup roll contour (flexible shape backup roll, in short FSR).
the rolls get deflected by high rolling forces. Elastic deformation of the mill takes place. If we use stiffer rolls, namely roll material of high stiffness or elastic constant, we could avoid mill spring. Normally elastic constant for mills may range from 1 to 4 GNm-1. Roll elastic deformation may result in uneven sheet thickness across.
Hot Rolling Mill Hydraulic Gap Control (HGC) thickness . be rolled several times on a reversing mill. Rolling is done by two work rolls, each supported by backup rolls. The maximum rolling force can reach 3-40000 kN. Typically, the roll gap is determined by set point of the main screws, located on both sides of the mill stand. Get Price
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 these mills can be as small as 6 mm diameter – made of tungsten carbide.
