THE DEVELOPMENT OF THE THEORY OF METAL ROLLING AND ITS APPLICATION TO ROLLING MILL CONTROL INTRODUCTION In the realm of process control it is the rigidness of specifica- tion upon the finished product which dictates the refinement neces- sary for adequate control. As the end product becomes more and more critical the solution to the control problem can no longer be
Steel Rolling :: Total Materia Article
Steel Rolling. Rolling is an indirect compression process. Normally the only force or stress applied is the radial pressure from the rolls. This deforms the metal and pulls it through the roll gap. The process can be compared to compression or forging but differs in two respects in that compression takes place between a pair of platens at ...
Tandem rolling mill - Wikipedia
If the Mill Stand Spring curve and the Compression Curve for the Strip are drawn against the same distance axes, then the intersection point gives the solution of expected Rolling Force F, and final Strip Thickness h, and also the required initial Screw-down position So.. In its simplest form h = S – S o – (F – F o) / M equation 4. This equation is known as the BISRA equation.

A steel rolling mill produces a sheet of uniform thickness from a slab of steel. It typically consists of several rolling stages, with rollers in each stage compressing the sheet of steel passing through it (Figure 1). In between the roller stages, looper stages maintain the tension in the sheet and prevent tearing and formation of slack.

The Calculation of Roll Force and Torque in Hot Rolling Mills
Abstract. Equations are derived for the normal roll pressure, specific roll load and torque in hot rolling mills, using the condition for plastic deformation in rolling derived by Orowan, together with von Kármán's equation of equilibrium. Although applying strictly to the rolling of ideal plastic-rigid materials, these equations may be ...

Crushing and cutting in roller mills.When the rolls move at the same speed (a), the beans are crushed by compression forces (shown by red arrows) as they are forced through the gap between the rolls. When the rolls move at different speeds (b), the particles are 'cut' by shear forces in opposing directions (shown by red arrows). Although both rolls are turning towards the centre, the ...

Rolling Process: Definition, Working Principle ...
Rolling Process Definition. The rolling process is a metalworking operation in which metal strips pass through a set of rollers to reduce sheet thickness and achieve uniform thickness throughout the sheet. The sheet is deformed along the linear axis. Typically after the rolling, metal sheets go through annealing which is done under a closed environment of nitrogen.
