Summary. The minimum achievable foil thickness is shown to be a function of the crossshear ratio, friction coefficient, deformation resistance, work roll radius, Young's modulus of work roll. As the rolling speed ratio increases, the crossshear ratio increases and the minimum achievable thickness decreases.
The roughing mill stands are used to reduce the thickness of the steel while at the same time extending the overall length. Rolling mill stand is an important part of a work stand, roll bearing chock and roller adjustment device is installed on the...

profiles, 4] Rotation of the axis of the work roll with respect to axis of backup roll in horizontal plane – results in deflection of work roll ends, producing camber. Roll flattening: There is increase in radius of curvature of rolls due to the roll pressure which causes elastic deformation of rolls. This is known as roll .

Because the roll system of the mill is symmetric on either side of the foil, only the upper half of the roll system was used for analysis (Fig. 4a).ω 0 is the WR rotation speed; rotation of the BR (at speed ω 1) is driven by contact friction force between the WR and the operation side (OS), the chock is constrained by the stand window in the horizontal direction and by the stop plate ...

To reach this thickness, the strip has to 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 340000 kN. Typically, the roll gap is determined by set point of the main screws, located on both sides of the mill stand.
