POWER IN ROLLING

POWER IN ROLLING Power is applied to the rolling mill by applying Torque to the rolls and by using roll strip total rolling load is distributed over the arc of contact. However, the total rolling load can be assumed to be concentrated at point along the arc of contact ata distance 'a' from the line of centers of the rolls. The ratio λ = [ a/Lp] = [a/√R.∆t] is used to ...

true rolling mill is first found as a sketch in the notebook of Leonardo da Vinci. There is no evidence that this was ever built. Before the end of the sixteenth century, at least two mills incorporating basic ideas of rolling are known to have been in operation.

Mathematical Modelling of Roll Cooling and Roll Surface Stress

In a rolling mill, the efficiency of roll cooling is one of the main factors on which the quality of the rolled products and the productivity of the mill depend. Improper or insuffi cient cooling of work rolls can not only lead to roll breakage due to excessive differential expansions but can also significantly affect the shape or crown of the roll and result in buckled strips. Another ...

What is Flywheel and How it Works?

Flywheel is a circular wheel attached to the crankshaft of the engine that stores the mechanical energy of the engine during power stroke and imparts that stored energy to the preparatory strokes ( suction, compression and exhaust stroke) during the engine working. It is made of steel or cast iron. It is mainly used in the engine and fabriing machines like rolling mills, punching ...
