Basics of AC Motors-Chapter 1rev - SITRAIN LMS

For example, consider a machine that unwinds a large roll of paper. If the roll is not moving, it takes a force to overcome inertia and start the roll in motion. Once moving, it takes a force in the reverse direction to bring the roll to a stop. Any system in motion has losses that drain energy from the system.

Steel Rolling Technology Handbook (2nd Revised Edition)

The very latest plate mills incorporate hydraulic roll positioning mechanisms and, for the control of plate profile and flatness, work-roll and/or backup-roll bending systems are utilized. Computers are now generally used for the control of new plate mills, as exemplified by the two-stand 157/124-inch mill at the Hoesch Dortmund Works.

Numerical Modelling and Simulation of the Hot Rolling Mill ...

In the design of the rolling mill plants, it is fundamental to study the behaviour of the deformation process to assess the main process variables (such as torque and rolling force) in all operating conditions.In this paper, a finite element model is developed and the numerical simulations of the plastic deformation process, in the hot rolling mill of AISI 304 stainless steel, are shown.

The Calculation of Roll Force and Torque in Hot Rolling Mills

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 applied to the ...

Why and How to Use a Roller? | Les Mills

Aug 15, 2018· Sit on the floor with the roller underneath the upper part of the ankles. Lift your hips off the floor and move your body down towards the roller (so the roller is rolling towards the knee). Move so that the roller is about an inch nearer to the knee, and then rock side-to-side for 15-30 seconds. Repeat inch by inch up towards the knee.
